A research team in Japan has won a US$1 million Milestone 2 award in the XPRIZE Healthspan competition for developing engineered “super exosomes,” microscopic biological delivery vehicles designed to target aging and damaged cells. Led by Professor Keisuke Goda of Tohoku University’s SiRIUS Institute of Medical Research and Graduate School of Medicine, in collaboration with researchers from the University of Tokyo’s Department of Chemistry, the team was selected from more than 600 competitors worldwide.
XPRIZE Healthspan is a seven-year international competition focused on extending the period of life people spend in good health. Participating teams are challenged to develop treatments capable of restoring muscle, cognitive, and immune function in adults between 50 and 90 years old. The competition sets a minimum target of reversing at least 10 years of biological decline, while the most ambitious goal is a 20-year improvement within one year or less of treatment. Goda’s team is now moving forward after receiving recognition for results obtained in aged animal studies.
At the center of the research are exosomes, naturally occurring nanoparticles released by cells. These membrane-bound vesicles normally transport proteins, lipids, messenger RNA, and other molecular signals between cells, functioning as part of the body’s communication network. Because exosomes can carry biological cargo and interact with specific tissues, scientists have been investigating them as potential alternatives to synthetic drug-delivery systems. However, naturally produced exosomes often lack sufficient targeting precision, limiting their ability to reach the cells most relevant to a disease or aging process.
The Tohoku-led group attempted to solve that problem by chemically modifying the surface of exosomes with lanthanide ions. Lanthanides are a family of metallic elements with distinctive electronic and chemical properties. According to the researchers, attaching these ions changes the surface behavior of the exosomes and substantially improves their ability to recognize and bind to senescent cells. The resulting particles have been named “super exosomes,” a term that reflects their enhanced targeting and delivery capabilities rather than a new biological category.
Cellular senescence is one of the major biological processes associated with aging. Senescent cells have generally stopped dividing because of accumulated damage or stress, but they do not necessarily disappear. Instead, some remain metabolically active and release inflammatory molecules, growth regulators, and other signals that can disrupt nearby tissues. This collection of secreted factors, often called the senescence-associated secretory phenotype, can contribute to chronic inflammation, impaired tissue repair, and the deterioration of organs. Precisely influencing these cells has therefore become a major objective in longevity research.
The proposed super-exosome platform is designed to deliver regenerative molecular cargo directly to aging tissues after attaching to senescent cells. Potential cargoes include growth factors, messenger RNA, and other genetic materials capable of altering cellular behavior. Rather than distributing such molecules broadly throughout the body, a targeted exosome could concentrate them near damaged or dysfunctional tissue. In theory, this approach could promote repair while reducing unwanted effects in healthy cells, although the degree of targeting and the durability of the response will need to be confirmed in human studies.
In preclinical experiments involving several groups of aged mice, the researchers reported statistically significant improvements in frailty, physical performance, and multiple functional measures associated with aging. They also described the treatment’s safety profile as excellent in the studies conducted so far. The team says the overall benefit corresponds to more than 15 additional healthy human years when estimated using cross-species lifespan scaling. Such calculations can help compare biological effects between species, but they are not evidence that a mouse treatment will extend human life by a specific number of years. Human biology, dosing, immune responses, and long-term risks could differ substantially.
The award will support the next stage of development: clinical studies planned in collaboration with Tohoku University Hospital and the Tohoku University Healthspan Research Center. These studies will need to establish how the particles behave in humans, how efficiently they reach senescent cells, what cargoes are most effective, and whether the treatment produces measurable improvements in strength, cognition, immunity, or other healthspan indicators. Researchers will also have to monitor possible immune reactions, unintended effects on healthy tissues, changes in tumor risk, and the persistence of engineered exosomes in the body. These questions are essential before claims of age reversal can move beyond the laboratory.
The platform could eventually be investigated for conditions involving muscle decline, cognitive impairment, immune dysfunction, hair loss, skin aging, and reproductive health. The team plans to commercialize the technology through NanoTitan, with the aim of developing scalable manufacturing and international distribution for exosome-based therapeutics produced in Japan. “Advancing to the XPRIZE Healthspan finals is an important milestone, but our ultimate goal is to translate this technology into therapies that allow people to lead healthy, independent, and active lives longer,” Goda said. The research now enters its most demanding phase: determining whether an impressive result in aged mice can become a safe, reproducible, and clinically meaningful treatment for people.

Falls among older adults often begin with changes too subtle to be noticed during an ordinary walk. A person may still appear steady while moving through a familiar environment, yet struggle when asked to divide attention between walking and another task. A new study by researchers Dong, Hu, Guo and colleagues examines whether machine-learning techniques can identify this hidden vulnerability in community-dwelling older adults by analyzing how gait changes during dual-task walking. Published in BMC Geriatrics in 2026, the research focuses on a potentially powerful combination of digital movement measurement and artificial intelligence: spatiotemporal gait parameters recorded while people walk and perform a second mental or motor activity.
Walking is not a single, automatic action. It requires continuous coordination between the brain, muscles, sensory systems and balance mechanisms. When a person walks while counting backward, answering questions or carrying an object, the nervous system must distribute attention between locomotion and the competing task. This is known as dual-task walking. Older adults who have limited cognitive or physical reserve may respond by slowing down, shortening their steps, widening their base of support or becoming more irregular in their timing. These adaptations can provide clues about fall susceptibility that may remain invisible during conventional clinical walking tests.
The study’s central idea is that gait should be evaluated under realistic cognitive pressure rather than only in ideal, distraction-free conditions. Spatiotemporal gait parameters describe measurable features of movement across time and space, including walking speed, stride length, step time, cadence, stance duration and the variability between consecutive steps. In a dual-task setting, researchers can also examine the degree to which these variables change compared with normal walking. This difference, often called dual-task cost, can reveal how much a person’s mobility is affected when attention is divided. A larger cost may indicate reduced ability to manage competing demands while remaining stable.
Machine learning offers a way to analyze these patterns simultaneously. Traditional clinical assessment may focus on one or two measurements, such as walking speed or the number of previous falls. A machine-learning model can process many variables at once and search for combinations associated with elevated risk. Depending on the model design, the system may learn from labeled examples, in which participants’ gait data are linked to fall-related outcomes, and then estimate risk for new individuals. Algorithms can detect nonlinear relationships that are difficult to capture with conventional statistical methods, although their usefulness depends heavily on the quality, size and representativeness of the data used for training.
The community setting is especially important. Many studies of balance and falls are conducted in hospitals or specialist laboratories, where participants may be healthier, more closely supervised or less representative of the broader older population. Community-dwelling adults live independently and encounter the complex conditions that make falls more likely: distractions, uneven surfaces, hurried movement, household obstacles and the need to perform several tasks at once. By focusing on this group, the research addresses a practical question for preventive medicine: can accessible gait testing identify people who appear independent but may require additional support before a serious fall occurs?
A potential advantage of this approach is its ability to move fall-risk assessment toward objective, repeatable measurement. Gait sensors, pressure-sensitive walkways, wearable devices or camera-based systems can convert movement into numerical data. Those data may be more sensitive than a brief visual observation, particularly when they capture step-to-step variability and changes induced by a secondary task. In the future, similar measurements could potentially be collected in clinics, rehabilitation centers or even at home. However, a prediction tool would need to be tested across different ages, health conditions, walking environments and technology platforms before it could be trusted for widespread use.
The research also highlights the technical challenges behind apparently simple predictions. Falls are influenced by numerous factors, including muscle strength, vision, medication use, reaction time, fear of falling, neurological disease and environmental hazards. Gait features alone cannot explain every incident. A machine-learning model may also perform impressively on the data used to develop it but less reliably on people from another population, a problem known as limited generalizability or overfitting. For clinical adoption, researchers must therefore evaluate calibration, sensitivity and specificity, test the model on independent datasets and make its decisions understandable to health professionals and patients.
Although the citation identifies the study’s objective and methodology, it does not provide detailed numerical findings such as sample size, predictive accuracy or the specific algorithm used. Those results will determine how close this technology is to practical deployment. Even so, the study reflects a broader shift in geriatric care: fall prevention is increasingly being treated as a problem of measurable, dynamic performance rather than a simple checklist of past incidents. By combining dual-task gait analysis with machine learning, the researchers are investigating whether the body’s response to distraction can serve as an early warning signal—one that could eventually help clinicians intervene before a dangerous fall changes an older person’s independence.

As populations age, scientists are looking more closely at a hidden biological process that may help explain why some older adults remain mobile and independent while others experience a rapid decline in strength, balance, and endurance. A systematic review by A. Boshnjaku, R. Obërtinca, M. Hoxha, and colleagues examines whether five inflammation-related biomarkers—CRP, high-sensitivity CRP, interleukin-6, interleukin-10, and tumor necrosis factor-alpha—are linked to physical performance in older adults living in the community. Published in BMC Geriatrics, the review focuses on a question with major implications for healthy aging: can signals circulating in the blood reveal who is at greater risk of losing physical function?
The study centers on chronic, low-grade inflammation, a biological condition often associated with aging and commonly described as “inflammaging.” Unlike the intense inflammation triggered by an infection or injury, inflammaging can persist quietly over years. It may be influenced by immune-system changes, excess body fat, physical inactivity, chronic disease, and cellular stress. Although inflammation is essential for repairing tissue and fighting pathogens, prolonged activation can affect muscle metabolism, blood-vessel function, nervous-system signaling, and energy production. These changes could, in theory, make everyday movements such as walking, rising from a chair, or climbing stairs increasingly difficult.
C-reactive protein, or CRP, is one of the most widely used indicators of systemic inflammation. It is produced primarily by the liver in response to inflammatory signals, especially interleukin-6. Standard CRP testing is useful for detecting relatively pronounced inflammatory activity, while high-sensitivity CRP, known as hs-CRP, can measure much lower concentrations. That distinction matters in research on older adults, where subtle inflammatory differences may exist even when there is no obvious acute illness. However, neither CRP nor hs-CRP identifies a single disease or proves that inflammation itself caused a decline in physical ability.
The review also considers three signaling proteins known as cytokines. Interleukin-6, or IL-6, can promote inflammation but also participates in muscle adaptation and energy regulation, making its effects highly dependent on timing, tissue, and physiological context. Tumor necrosis factor-alpha, or TNF-α, is a potent inflammatory mediator that can influence muscle protein breakdown and interfere with insulin signaling. Interleukin-10, or IL-10, generally acts as an anti-inflammatory regulator, helping restrain excessive immune activation. Examining these markers together offers a more nuanced picture than relying on a single laboratory value.
Physical performance is a crucial measure of aging because it reflects how effectively multiple systems work together. Muscle strength alone does not determine whether a person can remain independent. Walking speed, repeated chair stands, balance, grip strength, endurance, and composite tests such as the Short Physical Performance Battery can reveal the combined effects of the muscular, cardiovascular, neurological, and skeletal systems. For people living outside hospitals and care facilities, these measures may also provide a practical snapshot of resilience in everyday life. A small difference in performance can translate into a major difference in fall risk, mobility, and the ability to manage daily activities.
By bringing together evidence from studies of community-dwelling older adults, the authors address an important gap between laboratory research and real-world aging. Older people living independently are not a uniform group: some have multiple chronic conditions, while others remain highly active; some take anti-inflammatory medications, and others do not. Diet, smoking, obesity, socioeconomic conditions, sleep, recent infections, and exercise can all alter cytokine levels and physical performance. A systematic review can help determine whether associations between biomarkers and function appear consistently across this complex population or whether they vary substantially from one study to another.
The review’s importance lies not only in asking whether inflammatory markers are associated with poorer performance, but also in highlighting the limitations of interpreting such relationships. A high biomarker level may be a consequence of frailty, reduced activity, obesity, or an undiagnosed illness rather than the original cause of decline. Conversely, a single blood sample may fail to capture fluctuations in inflammation over time. Differences in laboratory methods, cutoff values, participant health, medication use, and performance tests can make studies difficult to compare. These issues are central when translating population-level associations into decisions about an individual patient.
The findings may ultimately support a broader approach to healthy aging in which inflammation is considered alongside strength, nutrition, cardiovascular health, cognition, and social environment. The biomarkers discussed in the review are not presented as standalone tests that can predict the future with certainty. Instead, they may help researchers understand why physical function changes and identify biological pathways that could be targeted through exercise, weight management, treatment of chronic disease, or other interventions. The study also underscores the need for longitudinal research capable of separating cause from consequence and for standardized testing that can connect laboratory signals with meaningful improvements in daily life.
For now, the review places a spotlight on the immune system as a possible contributor to the physical changes associated with later life. Its focus on CRP, hs-CRP, IL-6, IL-10, and TNF-α reflects the growing recognition that aging is not simply the result of muscles becoming weaker, but of interconnected changes across the body. Understanding how these inflammatory signals relate to mobility could help scientists develop more precise strategies for preserving independence—while reminding clinicians and the public that a blood test is most informative when interpreted together with a person’s functional ability, medical history, and lived environment.

Chronic pain is often treated as a medical problem that can be measured with scales, prescriptions, and clinical guidelines. For older adults, however, the experience of pain is also shaped by mobility, memory, sleep, mood, independence, and the ability to communicate with health professionals. A new study published in BMC Geriatrics places that lived experience at the center of the discussion, examining how older adults perceive chronic pain management in primary care settings.
The article, authored by P. Gopal, A. Kagarmanova, E. Staab and colleagues, focuses on a point where many long-term health decisions are made: the primary care clinic. Primary care clinicians are often the first professionals to evaluate persistent pain and the people most likely to coordinate treatment over months or years. This makes the setting especially important for older patients, who may be managing several chronic diseases and taking multiple medications at the same time.
Chronic pain is generally defined as pain that persists or recurs for longer than the expected period of tissue healing, commonly described as three months or more. It may arise from osteoarthritis, neuropathy, spinal disorders, previous injuries, cancer, or several conditions acting together. Unlike acute pain, which can serve as a warning signal, chronic pain involves complex changes in the nervous system. Repeated signals can increase the sensitivity of pain pathways, a process known as central sensitization, meaning that pain may continue even after the original injury has stabilized.
For older adults, treating this type of pain is rarely a matter of simply choosing a stronger drug. Age-related changes in kidney and liver function can alter how medicines are absorbed, processed, and eliminated. This can increase the risk of side effects from opioids, sedatives, anti-inflammatory drugs, and other treatments. At the same time, many older patients live with hypertension, heart disease, diabetes, dementia, or depression, conditions that can influence both the perception of pain and the safety of available therapies.
The study’s focus on perceptions is scientifically significant because clinical success cannot be judged only by changes in a numerical pain score. Two people who report the same intensity on a ten-point scale may have very different levels of disability, fear, sleep disruption, or confidence in their treatment. Older adults may value the ability to walk to the shops, sleep through the night, remain socially active, or avoid dependence on family members more than achieving complete elimination of pain. Understanding these priorities can help clinicians define treatment goals that are meaningful in everyday life.
Primary care also presents a distinctive communication challenge. Appointments may be brief, while chronic pain is influenced by physical, psychological, and social factors that require time to explain. Some patients may hesitate to report pain because they fear being dismissed, appearing demanding, or being prescribed medications they do not want. Others may assume that pain is an unavoidable part of aging. When these assumptions remain unspoken, clinicians can underestimate the burden of pain or recommend plans that patients cannot realistically follow.
A patient-centered approach attempts to address this gap by combining clinical evidence with the individual’s preferences, circumstances, and goals. In practice, that may involve medication review, physical therapy, exercise adapted to ability, occupational strategies, psychological support, sleep interventions, and education about pain biology. The technical principle is multimodal care: different treatments target different mechanisms and consequences of pain, potentially reducing reliance on any single intervention. For older adults, coordinated care can also help identify harmful drug interactions and prevent avoidable loss of function.
The research is arriving as health systems confront a rapidly aging population and growing demand for long-term pain care. Chronic pain affects quality of life, physical activity, and healthcare use, yet treatment remains inconsistent across communities. Access to physiotherapy, behavioral health services, specialist pain clinics, and transportation can vary sharply. These structural factors matter because a treatment plan may be clinically sound but ineffective if a patient cannot afford it, reach appointments, understand the instructions, or obtain help at home.
By examining older adults’ views, the paper contributes to a broader shift in pain research: away from treating patients as passive recipients of medical decisions and toward recognizing them as experts in their own daily experience. Their perspectives can reveal whether treatment goals are understandable, whether risks are being communicated clearly, and whether care plans fit real lives. Such information may help primary care teams design more responsive conversations about benefits, harms, uncertainty, and acceptable trade-offs.
The publication does not make the patient’s voice a decorative addition to pain medicine; it treats that voice as evidence relevant to clinical quality. As the medical community searches for safer and more individualized ways to manage chronic pain, the central question is increasingly practical: does the treatment help an older person live better, function more safely, and retain control over daily life? The study by Gopal, Kagarmanova, Staab and colleagues brings that question into primary care, where many of the most important decisions about persistent pain are made.

The Company posted quarterly revenue of $109.4 billion, up 16 percent year over year.
[…]
“Today, Apple is proud to report our strongest June quarter ever, with double-digit revenue growth across iPhone, Mac and Services, and in every geographic segment,” said Tim Cook, Apple’s CEO.
You can’t argue with the strong iPhone and Mac sales figures, and Apple specifically called out the MacBook Pro and the MacBook Neo, which Cook said “has been especially popular” and suggested that the company is still struggling to make them fast enough.
It’s admirable (and sensible) that Cook isn’t pointing fingers at anyone but customers who want Apple products, but the key phrase in his statement is “the supply chain just has less flexibility in it than normal.” This is an acknowledgement that while in the past, Apple might have been able to boost chip production from its partners, today the chip industry is maxed out thanks to the wild building of chips for AI applications.
[…]
As an aside, Cook also alluded to reports that Apple has tried to get the U.S. government to authorize purchase of RAM from some forbidden Chinese chipmakers, which has aroused political ire.
I’ve been covering Apple financial results and earnings calls for a very long time, dating back to my time at Macworld when Steve Jobs would occasionally parachute into earnings calls presided over by, among other people, Tim Cook! This week’s earnings call was Cook’s 90th and final installment, and that’s probably the most notable thing about it.
Even the fact that it was a record third quarter isn’t that notable. It’s more notable when Apple doesn’t set a quarterly record, especially given economic changes and inflation.
Still, as always, the results and the earnings call provided a few things I thought were worth pointing out. And so, powered by my second cup of tea while I’m on a summer trip to visit family (that was a late-night flight!), here are some thoughts about financial things.
It’s not a chip shortage, it’s demand
Apple is having supply-constraint problems. Maybe you’ve noticed the lack of new Mac minis and Mac studios? The Mac is the hardest-hit product line when it comes to supply, but Cook said the iPhone has also been affected, and anticipates constraints on the iPad as well.
This isn’t the whole story, of course, but it is part of it—and a part that Apple wants to crow about. Apple is limited in how many Macs, iPhones, and iPads it can sell because they are all powered by systems-on-chips that are coming off of chipmaker Taiwan Semiconductor’s most advanced production nodes. Here’s how Cook put it:
The root cause of it is not a regular supply issue. It’s a demand forecast issue, to be candid, where the iPhone and the Mac are both doing remarkably better than we thought they would do. And we had high expectations, so it wasn’t that our expectations were low, but as you can see from iPhone’s growth being 22% and Mac’s growth at 29%… these are extraordinary numbers and the supply chain just has less flexibility in it than normal. So we’ve been pulling supply ahead, and at some point there’s a limit to that. And so we’ve got a quarter that we’re going to be scrambling on the supply side, essentially.
This isn’t a partner or supplier issue. This issue is an incredibly strong… iPhone and Mac product cycle that has really yielded a demand beyond our expectation.
You can’t argue with the strong iPhone and Mac sales figures, and Apple specifically called out the MacBook Pro and the MacBook Neo, which Cook said “has been especially popular” and suggested that the company is still struggling to make them fast enough.
It’s admirable (and sensible) that Cook isn’t pointing fingers at anyone but customers who want Apple products, but the key phrase in his statement is “the supply chain just has less flexibility in it than normal.” This is an acknowledgement that while in the past, Apple might have been able to boost chip production from its partners, today the chip industry is maxed out thanks to the wild building of chips for AI applications.
Still, I do take Cook at his word: Even in a normal world, there’s only so much TSMC could do to rapidly respond to a dramatic increase in chip orders from Apple. I’m sure Apple is kicking itself for not anticipating stronger demand, especially given how tight the whole industry has gotten. And Cook’s suggestion that Apple is going to be “scrambling on the supply side” because the impact will “increase significantly” (and Cook really emphasized that word!) suggests that this may get worse before it gets better.
Oh yeah, and this isn’t just about cutting-edge SOCs. It goes for memory too. According to Cook, the price Apple pays for memory just keeps going up, and the offsetting Apple has been able to do by using existing inventory is going to be less effective as supplies run out.
As an aside, Cook also alluded to reports that Apple has tried to get the U.S. government to authorize purchase of RAM from some forbidden Chinese chipmakers, which has aroused political ire. “Obviously if there were more suppliers, that would be good, and it would help us on the supply side and perhaps the pricing side.”
How does Apple increase prices?
One of the analysts on the earnings call asked a question about Apple’s recent price increases, which was a great opportunity for Cook to explain Apple’s pricing philosophy.
It started out pretty normal, with Cook pointing out the price increases were done “reluctantly” and only because it’s “a hundred-year flood on the memory pricing.” But then it got more philosophical:
In terms of our philosophy on dollars or percentages, we look at units, revenue, and margin, and then come to a business judgment as to how to handle that. And so it’s not a mathematical formula that gets us to a specific result or just looking at one dimension of that. We look at all three dimensions and think about it over the long term instead of a 90-day clock. Hopefully that helps.
Yep, that helps, Tim. Three-dimensional pricing. Imagine pricing as a cube, and you’ll finally see the Matrix.
Soft Services stories
Services revenue, while up year-over-year, was (shockingly?) not up sequentially for the first time in more than three years. Apple laid most of the blame at various foreign-exchange rate “headwinds,” but CFO Kevan Parekh also tried to blame the softness on a few other factors:
Theatrical gross from “F1: The Movie” last year
“Headwinds in mobile gaming”
Changes to the App Store business model worldwide, mostly driven by regulation
The U.S. court order allowing developers to link out of Apple’s payment model without penalty
It felt like a real stretch, and more of an opportunity to complain about the App Store being regulated and litigated. But I will admit that a softening in mobile gaming, which obviously drives a lot of App Store revenue, is an interesting data point. And it’s more interesting that Apple felt it was worth sharing.
But, Parekh went on to say, “Despite this, the App Store did set a June quarter revenue record.” So… maybe not the reason for the softness after all?
Apple is an EGOT
Did you know that Steven Spielberg just won a Grammy award, which made him an EGOT? Winning an Emmy, Grammy, Oscar, and Tony is a pretty rare accomplishment that any individual should be proud of.
But did you know that large corporations are also keeping score? It’s true.
“It was wonderful to see Apple TV earn the industry’s top honors, adding Tony Awards this year to its Emmy, Grammy, and Oscar wins,” Cook said Thursday. “We reached that milestone faster than any streamer in history.”
I wonder which marketing person at Apple had the job of figuring out how quickly every other streamer became an EGOT. Also, thanks to cancelled series “Schmigadoon” for the Tony. Maybe do everyone a solid and bring it back?
This was Tim
Through the earnings call, financial analysts showed their softer side by thanking Cook for all his years of service and revenue generation. Cook made a point of thanking them all individually before answering their questions, which I thought was a nice, and human, touch. He also made a final farewell statement designed to warm Wall Street hearts:
Thank you to all of you, from our shareholders, particularly our long-term shareholders who have put their trust in us for so many years, to the analysts who have followed our company so closely. As you know, this will be my final earnings call, and John will lead these calls going forward. The transition is going seamlessly, and I am beyond excited for John to step into his new role and lead Apple into its next era. He is truly one of a kind and there is no better person to take the helm of the company.
Oh! The new guy! I didn’t even mention it, but John Ternus was on the call the entire time, and didn’t say a peep. At least, not until Wamsi Mohan of Bank of America decided to devote one of his two questions to him. He threw him a softball about how the competitive landscape is changing overall.
Ternus did not pick up the ball.
“Well, thank you for asking,” Ternus said, rousing from his call-long slumber. “I guess I would just reiterate what Tim said, there is so much opportunity for us with everything that’s happening in this space, and we’re just really focused on our plans and very excited about it.”
Deferring to the big guy and not letting Wamsi Mohan bait you into stealing Cook’s moment. That’s future CEO thinking right there, pal.
For the 90th and final time, Apple CEO Tim Cook hopped on a conference call with financial-industry analysts to detail the quarter gone by, give a peek at what’s to come, and maybe take one final victory lap. CFO Kevan Parekh and incoming CEO John Ternus were there, too.
This is Six Colors’s complete transcript of the call for July 30, 2026.
Tim Cook’s introduction
Thank you, Suhasini. Good afternoon, everyone, and thanks for joining the call. Today, Apple is pleased to report $109.4 billion in revenue, up 16% from a year ago and a June quarter record. We were able to achieve this despite supply constraints and sequential foreign exchange headwinds.
We continue to see enormous customer enthusiasm for our most popular lineup ever, with iPhone revenue growing 22% from a year ago to reach a June quarter record. We saw so much excitement around the best Mac lineup we’ve ever had, growing a strong 29% to achieve a June quarter revenue record. Services also set a June quarter record with $30.7 billion in revenue.
We achieved June quarter revenue records in every geographic segment. We were pleased to see strength across the board with June quarter records in the U.S., Latin America, Western Europe, India, China mainland, Japan, and Southeast Asia. We also achieved June quarter revenue records in both developed and emerging markets and saw double-digit growth in most emerging markets.
This year’s WWDC was a wonderful showcase of our latest innovations. We were tremendously excited to unveil the all-new Siri AI, a completely reimagined version of Siri that is profoundly capable, deeply personal, and integrated seamlessly across our platforms. And we’ve been absolutely thrilled by the response who’ve been using Siri AI in the developer and public betas. The reviews from early users have been phenomenal, and it’s been so wonderful to hear from people who are excited about the capabilities we’ve built. And it underscores our philosophy that building AI that is private and based on personal context can change how users find information and get things done with our products in a way that truly enriches their lives. We really couldn’t be more excited about it, and we are feeling incredibly enthusiastic about the impact it’s going to have.
At WWDC we also announced new tools to help parents keep kids safe online and we were pleased by the overwhelmingly positive reaction. New child safety features like Ask to Browse and Time Allowances will help parents encourage kids to develop healthy digital habits. These new tools integrate guidance from leading clinical and child development research, including the American Academy of Pediatrics. Our goal is to make it easier for parents to manage what their children see, who they interact with, and how and when they can use their devices. We’re looking forward to bringing these new capabilities to users this fall, in addition to amazing new updates across our operating systems.
Now let me turn to the results for the quarter, beginning with iPhone. iPhone revenue for the June quarter was $54.3 billion, up 22% from a year ago. We achieved June quarter records in every geographic segment, and set a June quarter record for upgraders. According to IDC, we gained share globally during the quarter. As I’ve said before, this is the most powerful and most popular iPhone lineup we’ve ever had. More people are relying on iPhone every day for AI, powered by the outstanding performance of A19 and A19 Pro. Across the lineup, iPhone continues to deliver the performance, battery life, durability, and camera capabilities that people count on every day. Whether it’s the extraordinary camera system of iPhone 17 Pro and Pro Max, the remarkably thin design of iPhone Air, the balanced performance and durability of iPhone 17, or the exceptional value of iPhone 17E, there’s an iPhone for every customer.
Mac delivered its best June quarter yet, with $10.4 billion in revenue, growing an impressive 29% from a year ago despite significant supply constraints. This revenue growth was driven by the incredible strength of our latest lineup, with MacBook Pro and the all-new MacBook Neo. According to IDC, we gained share globally. We also set a June quarter revenue record in developed markets and an all-time record in emerging markets with particular strength in Greater China, where we had an all-time revenue record. In addition, we achieved all-time records for upgraders and customers new to Mac.
With the power of Apple Silicon, the Mac lineup delivers outstanding power-efficient performance, massive memory bandwidth, and next-level AI capabilities. Mac continues to be the ultimate AI powerhouse, excelling at high throughput, on-device inference, and creation across a broad range of AI workloads. And we’re seeing customers increasingly put those capabilities to work, from using Mac Mini as a powerful platform for agentic AI to deploying clusters of Mac Studio systems to run frontier-class models locally.
Across the lineup, customers continue to embrace the Mac family. MacBook Neo has been especially popular, with its distinct design and excellent value resonating with customers around the world, and we’re continuing to work hard to meet demand. MacBook Air, the world’s most popular laptop, continues to deliver the portability and performance customers love with M5. And MacBook Pro, powered by M5 Pro and M5 Max, remains a go-to choice for professionals tackling the most demanding AI, development, and creative workflows.
In iPad, revenue was $6.2 billion for the June quarter. iPad continues to be the ultimate go-anywhere, do-anything device for students, entrepreneurs, and creators of all kinds, thanks to its incredible power, portability, and versatility. The addition of M4 to iPad Air has made it even more capable, delivering a significant performance boost for everything from personal productivity and immersive learning to advanced creative workflows. Together with a remarkable performance of iPad Pro, the amazing value and versatility of iPad, and the ultra-portable iPad Mini, we’re offering customers our strongest iPad lineup ever.
Revenue for Wearables, Home, and Accessories was $7.9 billion, up 6% from a year ago. We grew in every geographic segment and achieved a June quarter record for upgraders for Apple Watch. Our Apple Watch lineup brings together the most comprehensive set of health and fitness features we’ve ever had. We’re delivering useful features backed by research to enable users to better understand their health and wellbeing. It’s gratifying to receive almost daily reminders of the meaningful impact Apple’s health innovations are having for users all over the world—changing, even saving lives.
Meanwhile, we continue raising the bar across our AirPods lineup, whether it’s the immersive listening experience of AirPods Pro 3, or the premium listening experience and exceptional active noise cancellation of AirPods Max 2. And with live translation powered by Apple Intelligence, people are crossing language barriers and connecting like never before.
As I mentioned earlier, we’re excited about the work we’re doing on the next generation of Apple Intelligence, including Siri AI and the AI features we’re developing across our platforms. These experiences are intuitive and useful, while also deeply integrated in a way that’s personal and private, with the latest models running on device and on servers using Private Cloud Compute. We began laying the groundwork for users to have the best possible experience with AI when we introduced the Neural Engine in 2017. Ever since then, we’ve innovated and invested deliberately in silicon, systems, and scalable unified memory architecture designed with AI at their core.
What sets Apple apart is the unique combination of massive unified memory bandwidth, industry-leading power-efficient performance, and deep on-device intelligence, all built around the customer experience from the ground up. The result is that Apple has created the world’s best hardware to experience AI, whether using Apple Intelligence, including Siri AI, or third-party offerings. That’s why developers and researchers are increasingly using Apple devices to build ever-more advanced tools and models.
Turning to services, revenue was $30.7 billion, a June quarter revenue record and up 12% from a year ago, despite significant sequential foreign exchange headwinds. We also set an all-time revenue record in developed markets and a June quarter record in emerging markets. Apple TV continues to leave audiences spellbound with new releases like Widow’s Bay and Cape Fear alongside returning favorites like Silo and Sugar. And next week, we’re excited that Ted Lasso is back for its fourth season.
It was wonderful to see Apple TV earn the industry’s top honors, adding Tony Awards this year to its Emmy, Grammy, and Oscar wins. We reached that milestone faster than any streamer in history. We’re also looking forward to this year’s Emmy Awards, where Apple has landed a record 89 nominations, leading all networks in both the major drama and comedy series categories with three outstanding drama series nominations and three outstanding comedy series nominations. Widows Bay also stands out as the year’s most nominated new program, earning 19 Emmy nominations. In the six and a half years since launch, Apple TV has earned more than 850 wins and nearly 3,800 nominations.
In time for the World Cup, we expanded Apple Sports to include more than 170 countries and regions worldwide and made it easier than ever for fans to follow every moment of the tournament from the opening game to the final whistle. At the same time, we’re halfway through an unforgettable year of F1, and Apple TV subscribers have been tuning in all season to follow their favorite drivers and teams.
In retail, we were pleased to announce Apple Upgrade this week for customers in the U.S. Apple Upgrade is a new hardware leasing program launched in partnership with Klarna and makes it even easier for customers to get their hands on Apple’s latest products with a plan that’s right for them.
In all of our work, we’re thoughtful and intentional in how we show up for our users and across our communities. That means innovating to protect user privacy with the next of Apple Intelligence or helping parents keep kids safe, as I mentioned earlier. In honor of Global Accessibility Awareness Day, we unveiled new features to help users get more out of the products they use every day. New intelligent capabilities are coming to VoiceOver, Magnifier, Voice Control, and Accessibility Reader to make them more useful and intuitive. We’re also using on-device speech recognition to generate subtitles for video content without captions. And Apple Vision Pro is adding a feature for power wheelchair users to control drive systems using just their eyes. All of these features were born out of Apple’s longstanding commitment to ensuring that the benefits of technology are shared with everyone.
As we continue to develop new capabilities for users around the world, we’re also doing our part to invest in innovation close to home. Last year, we made a $600 billion commitment to the U.S. over four years, and now, as we said before, we plan to reinvest the tariff refunds we’ve received into the U.S.
We’re pleased with the progress we’ve already made advancing the American supply chain. Earlier this month, Apple announced a new agreement with Broadcom to design and produce custom silicon components and cutting-edge wireless connectivity technologies. The new, multi-year agreement with Broadcom, which is part of Apple’s American Manufacturing Program, is expected to exceed $30 billion. This marks our largest-ever American Manufacturing Program commitment. It’s also an important step forward in our work to build an end-to-end silicon supply chain here in the U.S.
We’re excited for the upcoming opening of the Apple Advanced Manufacturing Center in Houston. The center is located in a facility where we currently assemble advanced AI servers. Later this year, we’ll make Mac mini there, too. The center will teach students, supplier employees, and business of all sizes, the same innovative processes we use to make our products. The goal is to empower American manufacturers to take their work to the next level and strengthen the entire advanced manufacturing ecosystem.
We have an exciting fall ahead and an incredible future beyond. Our road map is phenomenal, and we are so excited about the way Siri AI will enrich our users lives. Throughout all of it, we will remain guided by our North Star: building the best products and services to enable people to do magical things. It’s a special privilege to be part of people’s lives in lasting and meaningful ways, helping them to create, connect, and experience the world around them. I couldn’t be more excited to watch our phenomenal story of innovation continue to unfold, and I’ve never been more confident that the best is yet to come. With that, I’ll turn it over to Kevan.
Kevan Parekh’s opening remarks
Thanks, Tim, and good afternoon, everyone. Here’s a quick rundown of our key financial metrics. Our revenue of $109.4 billion was up 16% year over year, a June quarter revenue record. We saw strong performance around the world with double-digit growth in every geographic segment despite supply constraints. Products revenue was $78.7 billion, up 18% year over year, driven by double-digit growth on iPhone and Mac, both of which set new June quarter records.
Our installed base of over two and a half billion active devices has reached another all-time high across all major product categories and geographic segments. Services revenue was $30.7 billion, up 12% year-over-year. We set revenue records in every Services category, including all-time records in cloud services and payment services. Company gross margin was 50.1%, up 80 basis points sequentially. This included a benefit from tariff refunds, which had a favorable impact of approximately two percentage points. When you remove this favorable impact, we would have been at the midpoint of the guidance provided last quarter.
Products gross margin was 40.1%, up 140 basis points sequentially. This also included a benefit from the tariff refunds I just mentioned, which had a favorable impact of over 2.5 percentage points. Services gross margin was 75.6%, down 110 basis points sequentially, driven by a different mix. Operating expenses came in at $19.1 billion, up 23% year-over-year, driven by investments in R&D. Net income was $29.8 billion. Diluted earnings per share was $2.02, up 29% year-over-year, and included 11 cents of favorable impact from tariff refunds. Operating cash flow was very strong at $34.4 billion. All three of these metrics set June quarter records, even when excluding the tariff refund benefit.
Now I’m going to provide some more details for each of our revenue categories.
iPhone revenue was $54.3 billion, up 22% year-over-year, driven by the iPhone 17 family. We grew double digits in the vast majority of markets we track and reached June quarter revenue records across both developed and emerging markets. The iPhone active installed base grew to an all-time high and set a June quarter record for upgraders. According to a recent survey from Worldpanel, iPhone was a top-selling model in the U.S., urban China, the U.K., France, Australia, and Japan. We were thrilled with the response to the iPhone 17 family. Customer satisfaction in the U.S. was recently measured at 99% by 451 Research.
Mac revenue was $10.4 billion, up 29% year-over-year, a new June quarter record, driven by the strength of MacBook Neo and MacBook Pro. We grew in both developed and emerging markets, with strong double-digit growth in markets like Latin America, India, and Southeast Asia. The customer reception to MacBook Neo has been incredible. We continue to attract new customers to the product around the world. As Tim mentioned, Mac had its best quarter ever for customers new to the Mac and for upgraders worldwide, including in the U.S., China mainland, and India. And in the U.S., customer satisfaction for Mac was recently measured at 95%.
iPad revenue was $6.2 billion, down 6% year-over-year, driven by the continued difficult compare against the launch of the A16 powered iPad in the prior year. At the same time, the iPad installed base reached a new all-time high, and over half of the customers who purchased an iPad were new to the product. And 451 Research recently measured customer satisfaction at 98% in the U.S.
Wearables, Home and Accessories revenue was $7.9 billion, up 6% year-over-year, driven by strength in wearables and accessories, and we saw growth in both developed and emerging markets. The wearables installed base reached a new all-time high. We set a June quarter record for upgraders on Apple Watch, and over half the customers purchasing an Apple Watch during the quarter were new to the product. And in the U.S., customer satisfaction on Apple Watch was reported at 95%.
Our Services revenue reached a June quarter record of $30.7 billion, up 12% year-over-year, despite significant sequential FX headwinds. For the total services business, we saw a double-digit growth in the vast majority of markets we track. We set records in every category, with June quarter records in advertising, App Store, AppleCare, music, and video, as well as all-time records in cloud services and payment services. We are optimistic about the long-term future of our services business. With our large installed base of over two and a half billion active devices, we have an incredibly strong foundation for growth opportunities. Our services continue to attract more customers, and we have now surpassed $1.5 billion in paid subscriptions. Both transacting and paid accounts reached new all-time highs in the quarter, with double-digit growth for both in emerging markets. And we continue to improve and expand our services offerings, from powerful updates to Creator Studio to exciting new features we’re bringing to services later this year, like splitting bills with Apple Cash using Visual Intelligence.
Turning now to enterprise and education, organizations are using the Apple platform to drive AI innovation and empower the next generation of students. Starting with Enterprise, Morgan Stanley has deployed over 20,000 iPhone 17 devices globally as part of a shift from employee-owned to corporate-owned devices for liability and security. More companies are choosing Mac for on-device AI advantages, including lower costs, better performance, and enhanced privacy and security. At Disney, creative teams are increasingly turning to Mac for on-device AI workflows that reduce overall cloud token costs and keep their IP secure. And Credit Agricole, France’s leading retail bank, is using on-device AI and MacBook Pro to streamline regulatory workflows, reducing manual processing time by over 80%. Our newest addition to the Mac lineup, MacBook Neo, is reaching new enterprise users in many environments, from bank branches to retail storefronts.
In education, MacBook Neo continued to accelerate adoption of Apple products, with many districts leveraging Apple financial services to deploy at scale. Pinellas County Schools, one of the largest districts in Florida, is transitioning 25,000 students from Windows devices to MacBook Neo across its 18 high schools. In Washington, Peninsula School District 401 moved over 8,000 students from Chromebooks to MacBook Neo. And in Oklahoma, Midwest City-Dell City School District purchased over 6,000 MacBook Neos to become an all-Apple district for students. In fact, in the last quarter, about half of the MacBook Neo large purchases by U.S. education institutions displaced Windows and Chromebook devices.
Let’s turn to our cash position and capital return program. We ended the quarter with $147 billion in cash and marketable securities and $84 billion in total debt. During the quarter, we returned $33 billion to shareholders. This included $4 billion in dividends and equivalents and $25.8 billion in share repurchases.
As we move ahead into the September quarter, I’d like to review our outlook, which includes the types of forward-looking information that Suhasini referred to. Importantly, the color we’re providing assumes that global tariff rates, policies, and their application remain in effect as of this call, and the global macroeconomic outlook does not worsen from today.
We also expect our September quarter total company revenue to be impacted by two main factors. First, we expect foreign exchange to be a sequential headwind of about 2.5 percentage points to the year-over-year total company growth rate from the June quarter to the September quarter. Second, we expect the impact from supply constraints to increase significantly sequentially. The projected supply constraints in the September quarter affect iPhone, Mac, and iPad. As a result, we expect our September quarter total company revenue to grow between 9% and 11% year-over-year.
On iPhone, we expect to continue to see high levels of demand; however, we do expect iPhone revenue to be impacted by these foreign exchange headwinds and supply constraints. Therefore, we expect the September quarter reported growth rate for iPhone to be mid-teens year-over-year. For Services, we expect September quarter year-over-year reported growth rate to be largely similar to what we reported in the June quarter after removing the negative sequential impact of about two and a half percentage points from foreign exchange that we just described.
We expect gross margin to be between 47 percent and 48 percent. This includes an expected benefit of approximately one percentage point related to tariff refunds. We expect operating expenses to be between $19.1 billion and $19.4 billion. We expect OI&E to be around $350 million, excluding any potential impact from the mark-to-market of minority investments, and our tax rate to be around 16.5 percent.
Finally, today our Board of Directors has declared a cash dividend of $0.27 per share of common stock payable on August 13, 2026, to shareholders of record as of August 10, 2026.
Before we take questions, let me turn it back over to Tim.
A farewell from Tim
Thanks Kevan. Before we get into questions, I just wanted to take a moment to say thank you. Thank you to all of you, from our shareholders, particularly our long-term shareholders who have put their trust in us for so many years, to the analysts who have followed our company so closely. As you know, this will be my final earnings call, and John will lead these calls going forward. The transition is going seamlessly, and I am beyond excited for John to step into his new role and lead Apple into its next era. He is truly one of a kind and there is no better person to take the helm of the company.
As I’ve said, I couldn’t be more confident in his leadership, in our executive team, and in the extraordinary people at Apple who are determined to enrich the lives of our users all over the world. We have a bright future ahead, and I truly have never been more optimistic. So thank you all, and now Kevan and I will be happy to take your questions.
Analyst Q&A
Amit Daryanani, Evercore: Tim, best of luck. It’s been a pleasure working with you over the years. Maybe to start with, if I think about the 9 to 11% sort of growth that’s guided for September, it’s about a 500 basis points or so deceleration versus what we’re seeing really in June quarter, even through this year, I would say. Can you just talk about how much of this decel is really supply constraint versus other factors like FX? And if you could just flesh out what these supply constraints are, broadening beyond these advanced SOCs you talked about last quarter as well.
Kevan Parekh: Amit, this is Kevan. How are you doing? Why don’t I start with just kind of describing the sequential change, and then I’ll let Tim jump in for kind of a bit more color around the supply constraints. So I think as I mentioned in my prepared remarks, we expect the September quarter total revenue to grow by 9% to 11% year-over-year, and then we expect that to be impacted by two main factors. So first, when we look at going from the June quarter to September quarter, we expect foreign exchange to be a sequential headwind of around 2.5 percentage points to the year-over-year company growth rate. And then the second impact is that the impact from supply constraints, we expect that to increase significantly when we go sequentially from June to September, and that projected supply constraint in the September quarter will affect the iPhone, Mac, and the iPad. And really, when you combine those two factors, we get pretty close to the June overall total company growth rate.
Tim Cook: Yeah, Amit, it’s Tim. First of all, thank you for your comments. During the June quarter, we did experience supply constraints primarily on the Mac and to a lesser extent on iPhone and iPad. These were driven by very high levels of demand, and as we’ve said before, we are seeing less flexibility in the supply chain than normal, and were primarily driven by the availability of the advanced nodes that our SOCs are produced on. If you look forward then into the current quarter, the September quarter, we continue to expect high levels of demand. However, with less flexibility in supply chain, we expect the impact from the supply constraints to increase significantly sequentially. The projected supply constraints in the September quarter, as Kevan said, affect iPhone, Mac, and iPad. And so, we’re seeing some very significant constraints currently, with limited flexibility in the supply chain to remedy it.
Amit Daryanani, Evercore: Got it. That’s really helpful. Thanks a lot for that. And then, Tim, I just have a memory question for you. Apple has historically, I think, done a really excellent job about delivering capability and utility to customers without really making them pay disproportionately more. The stagnant memory inflation seems to challenge that equation for you folks right now and there are reports that suggest that you’re seeking greater sourcing flexibility for memory. Can you just talk about, is this sourcing options really about ensuring that you have supply and it’s a way to mitigate memory inflation, or is more to preserve the value proposition for your customers. Just any light you could shed on this would be helpful. Thank you.
Tim Cook: Yeah, let me back up and talk about memory in general, ’cause I know this is a subject on many of your minds. As I’d said on the last call, we paid more for memory in the March quarter than the December quarter. And then, as I alluded to last quarter, we expected to pay significantly more in the June quarter than the March quarter, and that is what happened. It was partially offset by the benefit of carry-in inventory. For September, we expect to pay even higher memory costs. And we’re able to offset partly by a few factors, and let me walk through kind of what they are.
The first is, as you would expect, we have a benefit from some carry-in inventory in the September quarter. However, we believe this will see decreasing benefit from this over time, beyond the September quarter. The second is, we’re expecting lower costs on certain non-memory components that are in our BOM, and then if you look beyond September, we see the market pricing for memory continuing to increase, which could drive an increasing impact on our business, and we’re continuing to evaluate this.
In terms of the sources of supply, you know, primarily the DRAM market has three suppliers, and obviously if there were more suppliers, that would be good, and it would help us on the supply side and perhaps the pricing side. It’s unclear on the pricing side, but it could help on the supply side, and so, we’re evaluating all options.
Michael Ng, Goldman Sachs: Good afternoon. First, Tim, congratulations on the extraordinary run and [inaudible] on these earnings calls. In terms of my questions, I have two as well. First, on the Apple Upgrade program, could you talk a little bit about the expected adoption rates across your 2.5 billion device installed base in success? Do you see it shortening the replacement cycle for iPhone, or also having an equal impact to Mac and iPad, which may have not have benefited from device subsidies in the U.S. like iPhone has historically.
Tim Cook: Michael, first of all, thank you for your comments. I really appreciate that. If you look at the upgrade program, what it’s all about is making it easier for for customers to get their hands on our latest products with a leasing plan that’s right for them. And of course, as you know, the residual values on Apple products are generally much higher than the residual value on several of our competition, and so it’s a way to get into a product on a fairly affordable basis, particularly for those customers who want to upgrade on some kind of schedule, and so we’re very excited about it. It is offered in our retail stores, and so it’s not widely offered in all channels, and so we’ll see what the customer uptake is, but the early feedback on it is quite positive.
Kevan Parekh: Yeah, Michael, I just mentioned that it’s only available in the U.S. right now as well.
Michael Ng, Goldman Sachs: Great. Thank you. That’s very helpful, and then my second question, just on iOS 27 and Apple Intelligence. Went into public beta earlier this month. Could you talk about learnings from the public beta? Will the new Siri AI be a demand driver for iPhones this holiday? How does the Apple Intelligence usage to date in the open beta inform how you’re thinking about compute costs and the ability to recover some of those costs through iCloud Plus.
Tim Cook: Yeah, thank you for that. First of all, we are off the charts excited about Siri AI. We had a great reception from WWDC. We released the developer beta immediately after the keynote. The developer feedback has been overwhelmingly positive. The feedback from reviewers and so forth have been overwhelmingly positive. We released it to the public for a public beta a few weeks ago and the continued feedback is really, really great. I think it’s a very big idea have AI that’s private, that’s based on your personal context, and that’s integrated across the operating system, and so we couldn’t be happier with how things are going. In terms of what it means for compute cost, it’s obviously early going for us, and so I don’t want to say that we have a complete plan for that. We do believe there will be people that want to use it a lot, and so we will have some kind of upgrade possibilities on iCloud Plus where people can buy up the stack on iCloud Plus, and we’ll see how the pickup for that is. But we could not be more excited about where the product is.
Ben Reitzes, Melius Research: Hey, guys. Thanks a lot for the question, and obviously, Tim, known you a long time, I’ll really miss you. I wanted to ask about the supply constraints again, and I think people are just trying to make sense of it a little bit this way, is that the Street had you at 12% growth for the quarter of September, and so you could argue that to get to the 10% you guided, that’s just the FX, and then in the first quarter, which is December, the Street has been decelerating quite a bit, to like 8% to 9%. So I think what we’re struggling with after hours here is how much these supply constraints really hit you in December and impact that because, you know, the Street did a pretty good job of taking that number into the higher single digits. You know, is there any guidance you can give us there as you see it, Tim? And we’d really appreciate it. Thanks.
Tim Cook: Let me talk about the constraints a little more and then Kevan can weigh in on the guidance for revenue. As I had mentioned before, the primary issue is advanced nodes that we run our SOCs on. That’s the primary supply constraint now, and the root cause of it is not a regular supply issue. It’s a demand forecast issue, to be candid, where the iPhone and the Mac are both doing remarkably better than we thought they would do. And we had high expectations, so it wasn’t that our expectations were low, but as you can see from iPhone’s growth being 22% and Mac’s growth at 29%, and the iPhone is 22% year to date as well, that these are extraordinary numbers and the supply chain just has less flexibility in it than normal. So we’ve been pulling supply ahead, and at some point there’s a limit to that. And so we’ve got a quarter that we’re going to be scrambling on the supply side, essentially. And Kevan, you want to add on the revenue guidance?
Kevan Parekh: Yeah. Yeah, thanks, Tim. Ben, let me jump in here. The dynamics Tim mentioned combined with the foreign exchange impact I mentioned earlier sequentially is really what’s built into the 9 to 11 percent guidance we’re giving for the September total company revenue year on year growth rate. Beyond September, we’re not providing any color. At this point I think you mentioned December, so we’re not providing any kind of color or guidance beyond the September quarter.
Ben Reitzes, Melius Research: Ok. And then, if I could just ask, and you guys know what’s in the press all the time. But there’s this little company that is also building a fab in Arizona that you guys have been speculated you guys could work with that could potentially alleviate some, at least your silicon constraints. Is there any possibility that you guys broaden out your silicon providers in a reasonable time frame to alleviate these so we feel better about supply?
Tim Cook: Yeah, let me stress again, this isn’t a partner or supplier issue. This issue is an incredibly strong… it’s a great issue in some ways. It’s an incredibly strong iPhone and Mac product cycle that has really yielded a demand beyond our expectation. In Arizona, we do source over 100 million components this year out of Arizona. And so, it is part of our $600 billion commitment to the U.S., and we could not be more pleased with how that fab has ramped and is producing for us.
Eric Woodring, Morgan Stanley: Thanks so much for taking my questions, guys, and Tim, just echo what everyone is saying, it’s been a pleasure working with you. Hope to still talk to you in the future. I want to maybe focus on pricing here, Tim, and kind of unprecedented for you to take pricing in the ways that you have. I guess two related questions… Is it your intention to pursue some of these multi-year LTAs with your suppliers just to ensure access to supply at pre-agreed prices? And when you approach product pricing in this environment, is it your intention to protect product gross profit dollars? Is it your intention to protect product gross margins? We’d just love the kind of thought process behind the pricing.
Tim Cook: Yeah, on the pricing front, we reluctantly raised prices, I would say. And we did it because we’re in, what I would characterize as a hundred-year flood on the memory pricing with exponential increases in memory prices, and so that was the rationale for it. In terms of our philosophy on dollars or percentages, we look at units, revenue, and margin, and then come to a business judgment as to how to handle that. And so it’s not a mathematical formula that gets us to a specific result or just looking at one dimension of that. We look at all three dimensions and think about it over the long term instead of a 90-day clock. Hopefully that helps.
Eric Woodring, Morgan Stanley: Yeah, yeah, no, that does help. Thank you, Tim. And then just maybe a quick follow-up. I guess, Tim or Kevan. 12% services growth was just a bit below your guidance. I imagine FX maybe played a role there. I think the fiscal 4Q guidance assumes another deceleration. I think the math would imply below 10% year-over-year as reported. So can you maybe just help us understand the kind of function factors underlying that deceleration? And if that’s App Store, which I think some third-party data sources would suggest, is that a function of AI maybe reprioritizing time away from parts of the App Store? I just want to make sure we understand the moving pieces on services, please. Thank you so much.
Kevan Parekh: Hey, Eric. This is Kevan. I’ll take that one. So, let’s walk from kind of the 16 percent in our fiscal second quarter to kind of the 12% that we just talked about in the June quarter that you referenced, and we look at that, relative to the March quarter, foreign exchange was the main driver for the change in the year-on-year growth rate sequentially, and also a couple other factors to keep in mind. One is we had the theatrical release of F1, which is one of the highest grossing sports films in history, and this year we didn’t have a theatrical release. So that had a favorable impact on both the June quarter and also the September quarter in the year ago. We also had some factors that impacted the performance of the App Store. We did see some headwinds in mobile gaming, and then keep in mind, we also made some changes to the App Store business model in certain countries, and in the U.S., we do continue to operate under a court ruling impacting the link-out transactions. But we’re pleased the Supreme Court will hear our appeal. Despite this, the App Store did set a June quarter revenue record. So if we take a step back, there are several positive trends in the services business, and during the June quarter, we saw strong double-digit growth in categories like cloud services, video, payment services, and advertising, and we set revenue records in every category, with June quarter records in advertising, the App Store, AppleCare, Music, and Video, where Apple TV viewership reached an all-time high in the quarter. And then we also set all-time records in cloud services and payment services, where Apple Pay saw a record level of users in both developed and emerging markets. And services also had a June quarter record in emerging markets. And as we outlined in the prepared remarks, you know, our services continue to attract more customers, and we now have surpassed one and a half billion in paid subscriptions, and our transacting and paid accounts hit an all-time high, with double-digit growth in both those two and emerging markets.
So I think when I step back, if I look at, you know, kind of how we landed versus our expectations that we had outlined in the March quarter, for the June quarter, I would say that we roughly met our expectations, but we did see a bit more softness on mobile gaming in the App Store. As we go into the September quarter, what I would say is we expect foreign exchange will continue to be a headwind, and in fact this is a theme that’s impacting the services business moreso than the total company. We expect foreign exchange to drive about a 5 percentage point headwind to the year-on-year growth rate from the March to September quarter. So if we look at the sequential change from the June quarter, the 12% services we reported, to what we’re guiding for the September quarter, we are going to see another 2.5 point sequential headwind.
Aaron Rakers, Wells Fargo: Thanks for taking the questions and also best wishes, Tim. I guess I want to… maybe it tethers with the memory pricing dynamic, but as you look at the demand that you’re seeing right now, I’m curious of how you assess whether or not you’ve seen any pull forward of demand either from the consumer or even the enterprise and education markets, and whether or not you’re factoring that into your views as we look forward at all.
Tim Cook: You’re talking about on iPhone, I assume, in general. We’ve been running at this 22% growth rate for the last while, for this cycle has been a 22% increase year to date, and so it’s not obvious in the data that what you’re asking is true. Obviously, we’ve now had to increase prices on iPad and Mac, and the price elasticity there, it’s just too early to come to a definitive conclusion of what happens there. Because it takes a little while for the channels to adjust since there’s channel inventory and it takes a while for the consumer to respond, and so we’ll understand that more in the weeks ahead.
Aaron Rakers, Wells Fargo: Very helpful, and then as a quick follow-up, maybe more longer-term thematically, as AI proliferates towards the edge and more consumers utilize AI, I’m curious, Tim, if you see AI opening up additional opportunities. I can appreciate that you’re not going to give us specifics, but do you see other kind of addressable markets evolving from AI over time?
Tim Cook: Yes. I think there are enormous opportunities for Apple moving forward in AI. And I’m so excited about Siri AI and kind of where it is and where it’s going, and I’m excited about the feedback that we’re getting there, and of course, the ability to run some percentage of requests on device is also very strategic and sort of a competitive weapon, if you will. So I could not be more excited about the opportunities there.
Wamsi Mohan, Bank of America: Yes, thank you. Tim, first, congrats on your tenure as CEO. You joined back in 2011 when Apple reported $108 billion in revenue and you just delivered a quarter of $109 billion. So just an amazing journey.
Tim Cook: Thank you for that, I really appreciate it.
Wamsi Mohan, Bank of America: Yeah, sure, Tim, it’s been a pleasure. For my question, first on Siri AI, Do you expect that Siri AI would change the capital intensity of Apple, despite the fact that you have the ability to do so much differentiated workloads on device and you have this distributed compute? You do have some requests that go into the backend, both in your own first party cloud as well as third party. So is it right to think that the capital intensity of Apple will change in the future because of Siri AI?
Tim Cook: We use a hybrid model, as I know Kevan has reviewed with you earlier, and so we use some third-party cloud and we do our own data centers, and so there will be a mix. But generally speaking, as you know, we have been growing our OPEX and spending more in AI in general. Quite a bit more. And there are other locations on the P&L other than OPEX, like OCOGS, et cetera, that also have AI expenditures, and so we’ll see what Siri AI does from the cost side of it. But there’s also the ability when people use it a lot for them to move up on an iCloud plan as well, and so what the balance of that is, is a bit uncertain at the moment.
Wamsi Mohan, Bank of America: And John, since you’re on the call, congrats on the new role. I’d love to get maybe just a high-level take from you if you think that the competitive landscape here is changing, especially as you hear about, potentially, companies like OpenAI building an AI-enabled competitive device or SpaceX AI potentially having a phone that could bypass some of the typical carrier tax. Just would love your high-level thoughts on how you see the competitive landscape evolving and Apple’s position there.
John Ternus: Well, thank you for asking. I guess I would just reiterate what Tim said, there is so much opportunity for us with everything that’s happening in this space, and we’re just really focused on our plans and very excited about it.
Samik Chatterjee, J.P. Morgan: Hi, thanks for squeezing me in here and Tim, best wishes from my side as well. Maybe just for my first one, if I go back to WWDC when you announced Siri AI, you also did mention along with the rollout that probably we won’t have the initial rollout in China and Europe, so just wanted to get your thoughts on that front and any more color in terms of what hurdles you need to cross to be able to launch it in those regions.
Tim Cook: Thank you. Yeah, thanks for the question. Let me take them individually. If you look at the EU, we’re working closely with the Commission. Obviously, our complete desire is to launch everything everywhere at the same time. That’s always the philosophy that we have. We have not been able to do that in the European Union, but we’re working closely with them to try to get to something that would allow us to offer Siri AI there. It is offered, or will be offered for the Mac there, because the Mac is not covered by the same regulations as the iPhone and the iPad. So, net-net, we’re working with them, and hope to reach some sort of solution. If you then look at China, last week we received approval to ship sort of the original features of Apple Intelligence. Things like Clean Up and so forth, and so we’re working now through the rollout of those, and there will be more work required down the road for Siri AI, but we’re at the front end of that.
Samik Chatterjee, J.P. Morgan: Follow-up, Kevan, just not to beat sort of this FX thing to death here, but if I look at the gross margin, you delivered 48% in the quarter without the tariff refund benefit. You’re guiding to like 46 and a half. Any way to walk us through the sequential driver there and how much of that is FX impacting it versus maybe like increased commodity costs that’s driving that sequential moderation because it does seem a bit more atypical than your normal sort of years.
Kevan Parekh: Yes, that’s a good question. So let me walk through kind of what’s impacting our gross margins. We look at our gross margin change from the 49.3% we had a total company level for the March quarter, and as you mentioned, the 48.1% adjusted for the tariff refund in the June quarter, that hundred and twenty basis point change, if you look at the drivers of that, more than 100% of that can be explained by the memory cost change that Tim outlined. While FX was a factor, really the main driver was really the memory cost impact, and as Tim outlined earlier when we talked a bit about the dynamics around the memory cost, is we did see some partial offsets from things like the benefit of carry-in inventory, reduction in non-memory component costs, and some favorable mix. We are seeing the same dynamics when you go from the 48.1 that we printed in the June quarter to the 46.5 midpoint you referenced of our range without the tariff refund impact. That 160 basis point change is also… more than that is explained by the change in memory costs, and we had partial offsets, again, from things like the benefit of carrying inventory, lower cost and non-memory components, and as well favorable mix. I think that FX was a pretty minimal impact when you look at that versus the memory, and so generally, the sequential change from the March quarter to the 46.5 you referenced is really driven by memory.
Samik Chatterjee, J.P. Morgan: Great. Thank you both for taking my questions. And congrats again, Tim.
Tim Cook: Thank you so much for saying that, I appreciate it.
On Thursday, Apple announced record third-quarter earnings, with total revenue of $109.4B, up 16 percent from the year-ago quarter. iPhone revenue was up 22%, Mac revenue was up 10.4%, Services revenue was up 12%, and Wearables revenue was up 6%. iPad revenue was down 6%.
Shortly thereafter, Apple execs spent an hour on the phone with financial industry analysts, and we’ve got our usual complete transcript, including many farewells to Tim Cook.
And now, to help you visualize what Apple just announced, here is our traditional barrage of charts and graphs:
On Thursday afternoon, Apple will announce the results of its third fiscal quarter for 2026. It will presumably be the last appearance of Tim Cook on the post-release earnings calls, which he’s been doing for ages. In fact, today’s call will be his 90th. That’s more than two decades of talking on the phone once a quarter to financial analysts. He’s probably earned a break.
As usual, Six Colors will be here to report on the whole thing. Around 1:30 pm PDT, the company will release its financial reports and we’ll be on the scene with our usual load of colorful charts and some analysis. At 2pm PDT, it’s that hour-long phone call with analysts that I’ll also transcribe. Due to summer travel, we’ll be foregoing our usual post-results live stream (and there’s no Six Colors podcast this week, either), but you can tune in to the Upgrade podcast on Monday, where Dan will join me to break down all the results.
A newly published study reports that tropical cyclones were far more common during the Late Paleozoic Ice Age than many climate reconstructions have suggested. Led by Yan, Macarewich, Jiang, and colleagues, the work appears in Nature Communications (2026) and reframes how Earth’s cold interval coexisted with warm-water storm systems.
The researchers investigated geological signatures linked to extreme marine events, combining stratigraphic evidence with climate-model constraints. Their goal was to distinguish ordinary seasonal variability from the kind of widespread, repeated disturbances that characterize tropical cyclone belts.
A key technical advance in the study is the integration of paleoclimate boundary conditions with storm-resolving dynamical reasoning. Instead of treating cyclone activity as a simple function of temperature alone, the team considered large-scale patterns that govern where warm oceans can persist long enough to power rotating storms.
The results point to an expanded region of conditions favorable for cyclogenesis. Even though the planet was globally in an ice-age mode, ocean–atmosphere coupling—driven by uneven heat storage, changing circulation, and shifting storm tracks—likely enabled tropical systems to form across parts of the tropics more frequently than expected.
The authors describe “widespread” activity, implying that cyclone impacts were not limited to rare episodes. This interpretation aligns with the idea that cooling did not fully suppress tropical cyclone energetics; rather, it altered the geography and intensity distribution of storm-prone environments.
Using the preserved sedimentary record, the study connects storm activity to repeated depositional pulses. Those pulses, they argue, reflect basin-scale disturbance rather than local weather anomalies, strengthening the case for frequent tropical cyclone events during this interval.
From a broader perspective, the findings have implications for how we understand resilience and feedbacks in past climates. If cyclones continued to thrive under ice-age background states, then tropical extremes may persist through major global reorganizations.
The study’s viral potential is clear: it challenges an intuitive narrative that “ice ages mean calm tropics,” and replaces it with a more nuanced picture in which warm-water dynamics and circulation shifts can sustain storminess despite global cooling.

A new study reported in BMC Geriatrics spotlights cognitive reserve—the brain’s lifelong ability to adapt—as a potential resilience factor for how older adults experience frailty. The research frames frailty not as a fixed state, but as a dynamic process that can worsen or improve over time, with cognition playing a key role in that trajectory.
Frailty affects mobility, independence, and health outcomes, and clinicians increasingly treat it as something that evolves. Yet, why some people regain strength after health setbacks while others decline remains an open question. Zhao, Liau, Ma and colleagues investigate whether individuals who build stronger cognitive reserve across their lifespan may be better protected.
The team examines frailty progression and recovery in later life using longitudinal data, allowing participants to move between clinical frailty states rather than being categorized once and followed as static cases. This design is crucial for capturing real-world resilience, where improvement can occur after hospitalization, illness, or functional decline.
Cognitive reserve is often linked to differences in brain structure and function, as well as to lifelong experiences such as education, complex work, and engagement in mentally demanding activities. In the study’s framing, higher cognitive reserve may support more efficient neural processing and compensatory mechanisms, even when aging-related changes begin to accumulate.
Technically, the analysis explores associations between cognitive reserve measures and the odds of frailty worsening or recovering across follow-up. By considering longitudinal changes, the authors aim to isolate whether cognitive reserve is correlated with healthier trajectories, not merely with baseline health.
If validated, these findings could reshape how risk is assessed in geriatrics. Instead of focusing solely on current impairments, clinicians may consider cognitive reserve as part of a broader resilience model that includes cognitive health alongside physical function.
The implications extend beyond individual prediction. Cognitive reserve is influenced by modifiable factors, suggesting that public health strategies promoting lifelong learning and cognitively stimulating environments might contribute to better aging outcomes.
With its 2026 publication in BMC Geriatrics, the study adds to a growing evidence base connecting cognitive aging with systemic vulnerability. The authors argue that resilience is not only physical—brain adaptability may also buffer older adults against the downward cycle of frailty.
Finally, the study offers a viral-science-friendly takeaway: your brain’s “practice” over decades may help determine whether frailty becomes a chronic decline or a condition with room for recovery.

A new study highlights what shapes how older adults choose dental services, offering insights that could help clinicians and policymakers make care more reachable for aging populations. Published in BMC Geriatrics, the research examines preferences from the perspective of elderly people, focusing on the practical and psychological drivers behind where they seek treatment.
Researchers report that dental service choice is not determined by clinical need alone. Instead, older participants weigh multiple factors, including perceived quality, trust in providers, and the comfort they expect during visits. Such preferences can influence whether seniors present early for care or delay until symptoms become more severe.
The analysis also underscores the role of access-related conditions. Transportation difficulties, scheduling constraints, and the overall convenience of clinics can strongly affect whether elderly adults follow through on appointments. In practice, even when dental services are available, logistical friction can reduce uptake.
Cost perception emerges as another key theme. The study points to the way affordability, expected out-of-pocket expenses, and insurance-related clarity can shape willingness to seek preventive services. When costs feel uncertain, older adults may prioritize only urgent needs rather than routine checkups.
Beyond logistics and economics, communication quality matters. Participants appear to value providers who explain procedures clearly, demonstrate patience, and treat them with respect. For many seniors, feeling heard can improve satisfaction and reinforce continued engagement with dental care.
The findings also suggest that health-related experiences influence preference. Prior dental outcomes, fear of pain, and past interactions with the healthcare system can steer individuals toward specific service settings. This is particularly relevant for older adults who have accumulated years of unmet needs or negative impressions.
Importantly, the study frames these determinants as modifiable targets. By improving appointment accessibility, strengthening patient-provider communication, and ensuring transparent pricing, dental programs could better align services with senior expectations.
As populations age worldwide, these behavioral insights may help reduce barriers to oral healthcare. The research calls for strategies that address both the measurable elements of service delivery and the lived concerns of older adults deciding where to go for treatment.

A recent groundbreaking study unveils the complex landscape of unmet medical needs among the global aging population, offering new insights that could reshape healthcare policy and delivery. The research, published in a leading geriatrics journal, meticulously analyzes data drawn from a comprehensive national health service survey, revealing both the distribution patterns and deep-rooted inequalities affecting older adults’ access to medical care.
As the world’s population ages, the demand for healthcare services tailored to older adults is rising dramatically. Yet, this study reveals that many older individuals face significant barriers that prevent them from receiving timely and adequate medical attention. Utilizing advanced statistical models and large-scale population data, researchers identified critical demographic and socioeconomic factors linked with these unmet needs.
The findings highlight that unmet medical needs are not uniformly distributed but vary substantially across different segments of the elderly population. Income disparity emerges as a predominant determinant, with lower-income groups disproportionately affected. These individuals often encounter limited access to healthcare facilities, affordability challenges, and reduced availability of specialized geriatric services.
Furthermore, geographic location plays a decisive role. Older adults living in rural or underserved regions exhibit much higher rates of unmet medical needs compared to their urban counterparts. The scarcity of healthcare providers and transportation difficulties exacerbate these disparities, underscoring the urgent necessity for targeted interventions in healthcare infrastructure.
Another critical element revealed by the study is the influence of social support structures. Elderly individuals with limited family support or social networks experience greater hurdles in managing chronic conditions and accessing preventive care. This dimension adds a nuanced layer to understanding the intersectionality of healthcare inequalities among seniors.
Technological and systemic barriers also contribute significantly. Despite advancements in telemedicine and digital health platforms, a considerable portion of the older population remains digitally excluded, preventing them from leveraging these new modes of healthcare delivery. This technological divide further entrenches existing healthcare inequalities.
The research team employed rigorous analytical techniques to control for confounding variables, thereby isolating the independent effects of various risk factors. Their approach not only quantifies the scope of unmet medical needs but also provides actionable insights for policymakers, healthcare providers, and social services.
In a call to action, the study emphasizes the importance of multidimensional strategies that address economic, geographic, social, and technological determinants simultaneously. Tailoring interventions to these complex factors is paramount in ensuring equitable healthcare access for older adults and ultimately enhancing their quality of life.
As global demographics shift, this study serves as a critical resource for stakeholders striving to promote health equity among the aging. The detailed evidence underscores an urgent need to rethink current healthcare models by incorporating comprehensive measures that bridge gaps and dismantle barriers to care.

In the rapidly aging global population, mild cognitive impairment (MCI) has emerged as a critical area of focus for researchers dedicated to understanding and mitigating the progression of cognitive decline in older adults. Recent groundbreaking research has illuminated promising interventions, and among the most compelling is the application of Cognitive Control and Reasoning Training (CCRT). The latest study, conducted by Tan, Ping, Zhang, and colleagues, presents robust evidence that CCRT can notably improve cognitive function and modulate blood biomarkers in community-dwelling older adults experiencing MCI, offering a beacon of hope for preventative strategies in geriatric cognitive health.
At its core, Cognitive Control and Reasoning Training is a targeted, intensive cognitive exercise regimen designed to enhance executive functions—the brain’s system for managing attention, problem-solving, and flexible thinking. The new study rigorously quantifies the impact of CCRT through a multidimensional approach, combining neuropsychological assessments with advanced biomarker profiling from blood samples. This integrative methodology provides unprecedented insight into how cognitive training not only improves mental agility but also induces measurable physiological changes associated with brain health and neuroplasticity.
One of the most compelling aspects of this research is its focus on community-dwelling older adults rather than institutionalized populations, emphasizing real-world applicability and accessibility of CCRT interventions. By centering on MCI, a condition characterized by noticeable but not debilitating cognitive decline, the study targets a critical window of opportunity where intervention can potentially halt or even reverse the trajectory toward dementia. This shift in clinical focus is crucial, as it aligns with precision medicine’s broader goal of early detection and personalized intervention.
Methodologically, the study implemented a longitudinal design encompassing a sizeable cohort subjected to a structured CCRT protocol over several months. Participants underwent repeated evaluations using standardized cognitive batteries that assess memory, executive function, attention, and processing speed. Concurrently, blood samples were meticulously analyzed to detect variations in neuroinflammatory markers, neurotrophic factors such as brain-derived neurotrophic factor (BDNF), and markers indicative of oxidative stress. The dual assessment strategy enabled a holistic evaluation of both cognitive and systemic effects induced by the training.
The findings reveal statistically significant improvements in global cognitive scores among those exposed to CCRT, notably in domains linked to working memory and executive control—areas crucial for everyday function and independence. More intriguing, however, were the concomitant changes in blood biomarker profiles, suggesting that cognitive training may exert its benefits through systemic modulation of neurobiological processes. For example, elevated levels of BDNF, a key molecule involved in synaptic plasticity and neuronal survival, were observed post-intervention, signaling enhanced neuroadaptive capacity.
Another striking discovery was the reduction of pro-inflammatory cytokines in the participants’ blood samples following CCRT, underscoring the interplay between cognitive health and immune regulation. Chronic low-grade inflammation has been implicated in the pathogenesis of neurodegenerative diseases, and the ability of targeted cognitive training to attenuate these inflammatory pathways positions CCRT as a multidisciplinary therapeutic tool. Such biomolecular insights offer mechanistic explanations bridging behavioral improvements with underlying neurophysiology.
The implications of this study extend well beyond individual cognitive enhancement, challenging long-held notions about the irreversibility of age-related cognitive decline. The bi-directional relationship between brain function and peripheral biomarkers captured herein supports an emerging paradigm in neuroscience: that cognitive training is not merely a psychological exercise but a biologically rooted intervention capable of reshaping brain-body interactions. This realization paves the way for future integrated treatment strategies combining behavioral therapies with pharmacological approaches targeting neuroinflammation and neurotrophic support.
Importantly, the research team also addressed the sustainability of the cognitive and biological gains induced by CCRT. Follow-up assessments conducted several months post-intervention demonstrated that while some decline in measured benefits occurred, trained individuals retained significantly better cognitive functioning and biomarker profiles compared to control groups. This longevity suggests that CCRT programs may induce lasting neuroplastic changes, albeit emphasizing the need for continuous or booster sessions to maintain optimally enhanced cognitive states.
In parallel, the study highlights the feasibility of implementing CCRT in community settings, utilizing digital platforms and remotely supervised protocols, thereby overcoming traditional barriers such as mobility constraints and access to specialized care. By democratizing cognitive health interventions, this research heralds a new era where preventative cognitive maintenance can be integrated into routine elderly care, dramatically shifting public health strategies aimed at aging populations.
Moreover, the data illuminate potential predictive biomarkers that could be employed for precision targeting of cognitive interventions. Individuals who exhibited greater baseline neuroinflammatory markers and lower BDNF benefitted disproportionately from CCRT, suggesting that biomarker screening might inform patient selection and customization of training programs. Future clinical trials exploring dose-response relationships and personalized adjustments of training complexity are underway to optimize efficacy.
From a broader societal perspective, these findings carry substantial implications for reducing the global dementia burden. With populations aging rapidly worldwide, scalable interventions like CCRT could alleviate healthcare pressures by preserving functional independence and delaying institutionalization. Furthermore, the intersection of cognitive neuroscience and immunology as demonstrated here invites cross-disciplinary collaborations aimed at holistically addressing aging-related cognitive challenges.
While the study’s innovations are groundbreaking, the authors acknowledge several limitations requiring further exploration. The relatively short trial duration and modest sample size warrant larger, multicenter studies to validate and expand upon these results. Additionally, disentangling the specific cognitive components or mechanisms of CCRT responsible for biomarker modulation remains an open question, inviting sophisticated neuroimaging and molecular studies.
Nevertheless, this pioneering research reinforces the hopeful narrative that cognitive decline is not an inevitable consequence of aging but a modifiable condition amenable to targeted, science-backed interventions. The synthesis of behavioral training and biomarker tracking sets a new gold standard for developing interventions grounded in mechanistic understanding, moving cognitive health management toward a future where personalized, preventative care is the norm rather than the aspiration.
As public health systems grapple with the mounting challenges of neurodegenerative diseases, findings like these imbue the scientific community, clinicians, and caregivers with renewed optimism. By harnessing the brain’s inherent plasticity through methods like CCRT, we can envision a future in which older adults maintain cognitive vitality longer, enriching quality of life and sustaining autonomy well into advanced age.
This study by Tan et al. will undoubtedly spark extensive dialogue and inspire subsequent research into multifaceted cognitive therapies. As the field evolves, integrating cognitive training with nutritional, pharmacological, and lifestyle interventions could forge comprehensive, multimodal treatments. Such innovations promise to transform the landscape of brain aging, shifting the narrative from inevitability to empowerment.
In summary, the intersection of cognitive training and biomarker science elucidated by this study marks a monumental step in geriatric cognitive health. The compelling evidence for CCRT’s efficacy positions it as a cornerstone in emerging strategies designed to combat cognitive decline, offering scientific validation to a therapeutic approach that is accessible, scalable, and deeply rooted in our understanding of brain and body biology. The potential societal benefits underscore the urgency of expanding this research frontier to realize the promise of healthier cognitive aging for millions worldwide.

In the evolving landscape of anesthetic management for elderly patients, the impact of anesthetic agents on cognitive outcomes remains a critical area of investigation. Recent research published in BMC Geriatrics in 2026 has provided new insights into the differential effects of desflurane and propofol on perioperative neurocognitive disorders (PND) in older adults undergoing major urological surgeries. This randomized, controlled trial extends our understanding of how anesthetic choices may influence postoperative cognitive trajectories, a subject of immense importance given the increasing aging population and prevalence of complex surgeries in this demographic.
Perioperative neurocognitive disorders encompass a spectrum of cognitive impairments that arise in the perioperative period, including delirium and longer-lasting cognitive decline. Older adults are particularly susceptible due to age-related neurodegenerative changes, comorbidities, and the physiological stresses induced by anesthesia and surgery. Establishing whether specific anesthetics can exacerbate or mitigate these neurocognitive phenomena has significant implications for optimizing perioperative care and improving long-term functional outcomes for elderly patients.
The study under discussion rigorously compared desflurane, a volatile inhaled anesthetic known for its rapid onset and recovery, with propofol, an intravenous sedative-hypnotic agent valued for its favorable safety profile and neuroprotective properties observed in preclinical studies. The trial enrolled a robust cohort of older individuals scheduled for extensive urological procedures, randomizing them to receive either desflurane or propofol-based anesthesia. Cognitive function was meticulously assessed preoperatively and at multiple postoperative intervals using standardized neuropsychological tests sensitive to subtle cognitive changes, allowing for detailed temporal mapping of cognitive trajectories.
Findings from this investigation demonstrated notable differences between the two anesthetic regimens regarding the incidence and severity of perioperative neurocognitive disorders. Patients anesthetized with desflurane exhibited a higher frequency of early postoperative delirium and more pronounced cognitive decline at follow-ups compared to those who received propofol. These results resonate with emerging evidence suggesting that volatile anesthetics may contribute to neuroinflammation and neuronal stress, mechanisms hypothesized to underlie PND, whereas propofol’s antioxidative and anti-inflammatory effects potentially confer neuroprotection.
Critically, the study employed strict methodological standards to minimize bias and confounding, including blinding of outcome assessors and adjustment for variables such as baseline cognitive status, comorbidity burden, and surgical complexity. This rigorous approach increases confidence that the observed differences in cognitive outcomes stem from the anesthetic agents themselves rather than extraneous factors. Furthermore, the trial’s focus on major urological surgeries — procedures that are often lengthy and physiologically demanding — adds clinical relevance, as these patients typically face heightened risks of adverse neurocognitive sequelae.
The implications of these findings extend beyond a mere comparison of anesthetic efficacy and safety. They invite a reevaluation of perioperative protocols for elderly patients, advocating for anesthetic strategies that prioritize cognitive preservation alongside hemodynamic stability and analgesia. Propofol’s apparent advantage in attenuating PND risk may encourage clinicians to tailor anesthesia plans more judiciously, potentially integrating adjunctive measures such as enhanced monitoring of cerebral oxygenation and inflammation markers.
Mechanistically, the differential impact of desflurane and propofol on cognitive outcomes may relate to their interactions with neuronal glutamate receptors, modulation of synaptic plasticity, and influence on the blood-brain barrier permeability. Desflurane, despite its rapid elimination, has been associated with increased production of reactive oxygen species and microglial activation in animal models, processes that can trigger neuroinflammation and synaptic dysfunction. In contrast, propofol’s chemical structure facilitates scavenging of free radicals and suppression of pro-inflammatory cytokines, suggesting a neuroprotective milieu during the vulnerable perioperative period.
Additionally, this study sheds light on the critical period immediately after surgery, where interventions targeting delirium prevention could be best leveraged. The higher delirium rates observed with desflurane highlight the necessity for vigilant postoperative cognitive assessments and early rehabilitative efforts in patients exposed to volatile anesthetics. Conversely, the more favorable cognitive profile seen with propofol might translate into shorter hospital stays, reduced postoperative complications, and better quality of life trajectories, outcomes that remain to be explored in subsequent longitudinal research.
Beyond the direct effects on cognition, the choice of anesthetic also influences systemic physiological responses including hemodynamic fluctuations and respiratory function, which can indirectly affect brain perfusion and oxygenation. This study’s comprehensive monitoring protocols provide a nuanced framework for balancing these considerations while still focusing on optimizing neurological outcomes in frail and complex surgical populations.
The authors acknowledge certain limitations such as the single-center design and the need for larger-scale multicenter studies to validate these results across diverse patient populations and surgical contexts. Nonetheless, this investigation constitutes a significant advancement in the personalized management of anesthesia in elderly patients, framing future research priorities that integrate neurocognitive outcomes as central endpoints in anesthesiology trials.
In conclusion, this landmark trial delineates a clear divergence in neurocognitive outcomes based on the anesthetic agent used, favoring propofol over desflurane in terms of mitigating perioperative neurocognitive disorders in older adults undergoing major urological surgery. These insights compel a paradigm shift towards individualized anesthetic regimens that prioritize cognitive health, thereby enhancing recovery trajectories and long-term well-being in the vulnerable aging population. As the global burden of neurocognitive disorders grows, such targeted perioperative strategies stand poised to transform clinical practice and elevate standards of geriatric surgical care profoundly.

In the evolving landscape of geriatric health research, the intricate relationships among physical frailty, depression, and multimorbidity have surfaced as critical domains needing deeper understanding. An illuminating new study from Lima, Peru, conducted by Flores-Flores, Zevallos-Morales, Pollard, and colleagues, dives into these complex intersections, providing fresh insights into how these conditions coalesce and impact older adults in urban settings. This comprehensive cross-sectional investigation sheds light on the multifaceted vulnerabilities faced by the elderly, emphasizing the necessity for integrated care strategies tailored to their unique needs.
Physical frailty, a clinical condition marked by diminished strength, endurance, and physiological function, often predicts adverse health outcomes among older populations. Impaired mobility, increased risk of falls, and functional dependence are common sequelae, culminating in escalated healthcare utilization and mortality. The Peruvian study meticulously quantifies the prevalence of frailty within its cohort, uncovering how it interacts with psychological states and multiple chronic diseases, known collectively as multimorbidity.
Multimorbidity, the coexistence of two or more chronic conditions, poses an amplified threat to health resilience in aging individuals. Its management remains a formidable challenge for clinicians, as standard treatment protocols designed for singular diseases may overlook the cumulative burden posed by concurrent illnesses. By focusing on a sample representative of Lima’s elderly urban demographic, the researchers provide a culturally pertinent lens on multimorbidity’s role as a harbinger of frailty and mental health decline.
Depression, widely recognized as a common yet underdiagnosed affliction among older adults, further complicates the clinical picture. The emotional and cognitive burdens of depressive disorders compound the physiological vulnerabilities imposed by frailty and multimorbidity, often resulting in a downward spiral of functional capacity and quality of life. The study’s exploration of depression’s prevalence and its interplay with physical health outcomes underscores the bidirectional nexus between mind and body in geriatric well-being.
Utilizing a robust cross-sectional design, the research deploys validated instruments to assess frailty phenotypes, depressive symptomatology, and comprehensive comorbidity profiles. Such methodological rigor facilitates an accurate snapshot of health status within the sampled population, generating data of high relevance for both clinical application and public health policymaking. The results illuminate not only the individual prevalence rates but also the synergistic patterns that exacerbate vulnerability.
One of the startling revelations is the extent to which multimorbidity compounds the risk of physical frailty, emphasizing a cumulative pathophysiological burden. Chronic diseases such as diabetes, hypertension, and cardiovascular disorders—pervasive in aging populations—create systemic inflammation and metabolic disruptions. These processes accelerate sarcopenia and other degenerative changes, thereby eroding physical robustness and functional independence.
Depression emerges as both an independent and interconnected factor intricately woven into the frailty narrative. Beyond mood disturbances, depressive symptoms influence appetite, motivation for physical activity, and adherence to medical regimens. The study’s findings elucidate how depression can act as a catalyst, accelerating the progression from robust health to frailty, especially within the context of multimorbidity.
These intertwined conditions not only affect individual trajectories but also impose significant burdens on healthcare systems, particularly in middle-income countries like Peru. Limited resources, fragmented care models, and disparities in healthcare access amplify the challenges posed by these geriatric syndromes. This research punctuates the urgent need for integrated care frameworks that holistically address physical, psychological, and chronic disease dimensions.
The importance of early identification and intervention cannot be overstated. Screening programs capable of detecting frailty, depressive symptoms, and multimorbidity in primary care settings could enable timely mitigation strategies. Personalized interventions involving nutritional support, physical rehabilitation, mental health counseling, and optimized chronic disease management may collectively forestall the decline and improve outcomes.
Furthermore, socio-cultural factors uniquely shape the experience and management of these conditions. In the Peruvian context, family dynamics, community support structures, and traditional beliefs influence health behaviors and treatment engagement. Understanding these cultural nuances is paramount for developing culturally sensitive interventions and health promotion campaigns that resonate deeply with the target populations.
On a scientific level, the research opens avenues for mechanistic explorations into the biological underpinnings linking multimorbidity, frailty, and depression. Pathways involving neuroendocrine dysregulation, chronic systemic inflammation, and mitochondrial dysfunction are promising targets for future investigations. Disentangling these mechanisms will enhance the precision of diagnostic criteria and therapeutic innovations.
Public health ramifications extend beyond clinical settings. Urbanization, socioeconomic inequalities, and environmental exposures contribute to the health status of older adults, influencing the prevalence and interplay of frailty, depression, and multimorbidity. Urban planning and social policy reforms aimed at age-friendly environments are crucial adjuncts to medical interventions in fostering healthy aging.
The study also underscores the value of multidisciplinary collaboration in geriatric care. Incorporating geriatricians, psychiatrists, primary care providers, social workers, and rehabilitation specialists into cohesive teams can optimize management strategies. Training and resources must evolve to equip healthcare workers with skills necessary for navigating the complexities of multimorbidity and mental health amidst frailty.
Limitations inherent to the cross-sectional study design, such as the inability to establish causality, are acknowledged by the authors. Nevertheless, the rich associations outlined provide a foundation for longitudinal studies that track health trajectories and intervention impacts over time. Such prospective research is vital for developing evidence-based guidelines that adapt dynamically to aging populations’ needs.
Importantly, this investigation elevates the discourse on healthy aging within Latin America, a region undergoing rapid demographic shifts. The projected increase in the elderly proportion demands proactive strategies grounded in region-specific data, rather than extrapolated models from high-income countries. The Lima cohort study represents a significant stride toward localized understanding and responsive healthcare policy formation.
In conclusion, the intertwining phenomena of physical frailty, depression, and multimorbidity in the elderly represent a triad that shapes health outcomes profoundly. The Lima-based research elucidates critical interdependencies, advocating for integrative approaches that transcend siloed healthcare paradigms. As the global population ages, such nuanced perspectives are indispensable for crafting interventions that enhance longevity with quality, dignity, and resilience.

When older adults undergo surgery, doctors often focus on complications such as infections, bleeding, or heart problems. Yet one of the most common complications affects the brain. Known as postoperative delirium, this condition can cause sudden confusion, disorientation, memory difficulties, and changes in behavior. Many families assume that delirium is temporary. In some cases, symptoms […]
