In the final weeks before Romania’s presidential vote in November 2024, TikTok accounts that had previously spent years posting about manicures or fashion suddenly started promoting a little-known politician named Calin Georgescu.

His posts, espousing hard-line views on immigration and anti-Semitic tropes, were viewed 120 million times before the vote. Georgescu, who had previously been polling in the single digits, stunned observers by winning the election’s first round with 23 percent of the vote.

In the Netherlands, Adriana Iamnitchi was watching closely. As chair of computational social sciences at Maastricht University, she leads the research into disinformation campaigns. She wanted to know how pro-Georgescu content was being monetized on TikTok through hidden influencer marketing and livestreamed political content.

The Mars Climate Modeling Center (MCMC) conducts atmospheric and climate science research using the NASA Ames Mars Global Climate Models (MGCMs), advancing our understanding of Mars’ climate today, in its ancient past, and as a target for future exploration.

Mars’ climate is governed by three interacting cycles — dust, water, and carbon dioxide (CO₂) — that vary across seasons and from year to year. MCMC scientists use the MGCMs to study these cycles and the processes that drive them, including:

• Dust storms and dust transport – Investigating the mechanisms that lift, transport, and remove dust in the Martian atmosphere, including the onset and evolution of regional and global-scale dust storms.
• Water and CO₂ cycles – Studying the seasonal exchange of water and CO₂ between the atmosphere, polar caps, and surface, and the clouds that form as a result.
• Atmospheric dynamics – Examining circulation patterns, wave-mean flow interactions, and the extension of the MGCM into the middle atmosphere to better connect the lower and upper atmosphere.
• Ancient Mars and habitability – Reconstructing past climate states, including the role of asteroid and comet impacts, to assess when and where conditions may have supported liquid water and habitability.
• Mission support – Applying model results to landing site selection and characterization, atmospheric entry planning, and interpretation of data from current and past Mars missions.

This research is carried out by a team of civil servant and contractor scientists, postdoctoral researchers, and students, often in collaboration with universities and other NASA centers. You can read more about individual MCMC team members and their science on the Group Members page. A full list of MCMC research papers, conference presentations, and technical reports is available on the Publications page.

Apple is poised to make one of the most impressive debuts in recent smartphone history. According to Counterpoint Research’s latest forecast, the company’s first foldable iPhone is expected to capture a remarkable 25% share of global foldable smartphone shipments in 2026 — its very first year (really, quarter) in the category — while helping propel the overall market to robust 21% year-over-year growth.

This is no ordinary product launch. In a segment long dominated by a handful of Android players, Apple is projected to debut in a clear second place, ahead of Huawei (24%) and closing the gap dramatically on market leader Samsung, whose share is forecast to decline from 40% in 2025 to 32%. Motorola and HONOR are expected to see further erosion of their positions, underscoring how Apple’s entry is poised to reshape the competitive landscape overnight.

Global Foldable Smartphone Shipment Share by OEM, 2025 vs 2026F

What makes this projection especially powerful is the nature of the demand Apple is expected to unlock. Counterpoint notes that Apple’s arrival will intensify competition specifically in the premium book-type foldable segment—the form factor that prioritizes productivity, multitasking, and expansive screen real estate over pure novelty. As AI features evolve beyond simple chat into everyday workflows such as document summarization, content editing, schedule management, and seamless cross-app information movement, a wider, more flexible canvas becomes essential. Apple’s anticipated design approach aligns perfectly with this shift, positioning the foldable iPhone as a natural extension of the company’s longstanding focus on refined user experience, seamless ecosystem integration, and premium craftsmanship.

Samsung is set to retain the overall lead for now, but the narrowing of its advantage to just seven percentage points over Apple highlights the disruptive force of Cupertino’s entry. Other brands that once held meaningful shares are projected to lose ground, illustrating how a single, highly anticipated Apple product can redefine market dynamics and accelerate category maturation.

The 21% growth forecast for the global foldable market in 2026 is itself a vote of confidence in the category’s future, and Counterpoint explicitly ties much of that expansion to Apple’s influence. By bringing its massive, loyal customer base, rigorous attention to durability and software optimization, and unmatched brand prestige into the foldable arena, Apple is expected to expand the total addressable market rather than merely redistribute existing demand. Premium book-style devices stand to benefit most, moving foldables further from experimental gadgets toward mainstream productivity tools.

For years, observers have waited for Apple’s carefully timed move into foldables. The Counterpoint numbers suggest that timing was deliberate and strategic. Rather than rushing to market, Apple appears positioned to enter with a product that not only claims a quarter of all foldable shipments in its first quarter, but also elevates the entire segment—raising expectations for design excellence, software polish, and real-world utility.

In short, 2026 is shaping up as the year the foldable smartphone market comes of age, and Apple is set to be one of its primary architects. Capturing 25% share on debut is more than a strong start; it is a clear signal that when Apple decides a category is ready, the industry—and consumers — take notice.

MacDailyNews Take: And, in 2027, if they don’t actually exceed Counterpoint’s projection and claim the crown straight off in Q226, after a mere three months on the market, Apple’s iPhone will be No.1 in foldable smartphones. Apple’s well-heeled customer base guarantees it.

I ceppi batterici resistenti hanno progressivamente reso inefficaci molti antibiotici di ultima istanza, modificando le proprie pareti cellulari per impedire l'azione dei farmaci. Un team di ricerca guidato dal chimico John Moses del Cold Spring Harbor Laboratory, in collaborazione con Howard Hang di Scripps Research, ha sviluppato una strategia alternativa: anziché progettare nuove molecole antibiotiche, i ricercatori hanno mirato a disattivare i meccanismi di difesa dei patogeni. Il bersaglio dello studio è l'enzima secreted antigen A (SagA), un'idrolasi utilizzata dal batterio Enterococcus faecium per modellare la propria parete cellulare e nascondere i punti d'attacco del farmaco. Sfruttando la tecnica di sintesi chimica Diversity Oriented Clicking, il gruppo ha identificato la molecola pghi-4, capace di inibire l'enzima SagA. La somministrazione combinata di pghi-4 e vancomicina ha permesso di ridurre fino a otto volte la dose di antibiotico necessaria per eliminare i ceppi resistenti nei test di laboratorio, dimostrando un'efficacia confermata anche su modelli animali. L'approccio apre la strada al recupero di molecole farmacologiche storiche per contrastare le infezioni ospedaliere e altre patologie complesse.

Sleep has long been suspected to influence how aging bodies manage multiple chronic conditions, but the interplay between rest quality and physical decline has been harder to untangle. Now, a new cross-sectional study of Chinese older adults adds an evidence-packed twist: poor sleep and frailty are not just independently linked to cardiometabolic multimorbidity—they also appear to act synergistically.

Researchers analyzed how sleep quality and frailty relate to the co-occurrence of cardiometabolic disorders, focusing on patterns that emerge when both factors are present at once. Using statistical modeling suited for observational data, the team assessed whether the combined effect of sleep impairment and frailty exceeds what would be expected if each acted alone.

The findings point to independent associations in both directions. In other words, older participants with worse sleep quality were more likely to show cardiometabolic multimorbidity, and those with greater frailty also faced higher odds. This dual relationship strengthens the biological plausibility of the sleep–health link in late life.

But the headline result is synergy. The study suggests that the joint presence of insufficient or low-quality sleep and frailty corresponds to a disproportionately greater burden of cardiometabolic multimorbidity. Such interactions matter because they imply that tackling only one factor may leave a major portion of risk untouched.

From a mechanistic perspective, poor sleep can disrupt metabolic regulation, impair glucose homeostasis, and contribute to inflammatory signaling, all of which can accelerate vascular and metabolic dysfunction. Frailty, meanwhile, reflects reduced physiological reserve—often shaped by chronic inflammation, muscle loss, and stress-axis dysregulation—creating a vulnerable platform for cardiometabolic disease to cluster.

The cross-sectional design cannot prove causality, but it helps map where risk concentrates in real-world aging. The authors argue that clinicians and public health programs should consider sleep quality and frailty together, rather than treating them as separate problems.

In a Viral science news framing, the study’s message is clear: “better sleep” and “less frailty” may be more connected than previously assumed, potentially offering a more coordinated prevention strategy for seniors facing multiple cardiometabolic conditions.

Older adults in China are not experiencing health improvements evenly, and a new study links part of that gap to how physical activity is distributed across communities. Researchers report that physical activity is associated with better health outcomes, but the benefits are not uniform—creating measurable health inequality rather than a single “one-size-fits-all” effect.

The findings focus on older adults and examine whether differences in activity levels translate into unequal health trajectories across demographic and socioeconomic conditions. Instead of treating “activity” as a simple yes-or-no behavior, the analysis considers how gradients of movement relate to disparities in health.

To quantify inequality, the study employs population-level metrics commonly used in health economics and epidemiology. These approaches can separate overall health variation into components that reflect group differences, allowing investigators to estimate how much of the inequality is potentially attributable to physical activity patterns.

The work also emphasizes that health inequality can widen even when average health improves. In this scenario, some groups may adopt or maintain activity more easily—because of access to safe spaces, health literacy, social support, or fewer mobility constraints—while other groups fall behind.

Technically, the authors analyze observational data and control for key confounders that might otherwise explain both activity and health status. This helps reduce the chance that the observed association is merely driven by factors such as baseline chronic disease burden, education, or geography.

Importantly, the results suggest that physical activity does not just correlate with health—it may act as a modifiable lever shaping how evenly health benefits are shared. If interventions can shift activity patterns among disadvantaged groups, the study implies that inequality could shrink, not just outcomes improve.

Because the paper is based on real-world evidence from China, it also highlights cultural and structural realities that shape behavior. Urban design, community programming, and the availability of age-friendly exercise options may influence who can be active consistently.

From a “viral science news” perspective, the headline takeaway is straightforward: getting older doesn’t have to mean accepting unequal health. The study frames physical activity as both a health tool and an inequality amplifier—meaning targeting participation gaps could deliver outsized public health impact.
