A Assistência de Conectividade (Connectivity Assist) chegou aos iPhones e iPads com o iOS/iPadOS 27 — uma evolução do antigo recurso Assistência Wi-Fi.
Como o próprio nome indica, esse recurso ajuda você quando a rede Wi-Fi está instável ou lenta, usando dados celulares para melhorar a conexão.
Caso você se preocupe com o uso de dados celulares, talvez seja interessante desativar esse recurso. Mas, ainda que esse ajuste possa ser ativado e desativado para todo o sistema, a Apple também permite configurá-lo individualmente para cada rede — ou seja, você pode mantê-la habilitada em uma e desabilitada em outra.
O iOS/iPadOS 27 trouxe algumas novidades pequenas, mas muito interessantes para quem utiliza iPhones ou iPads diariamente.
Uma delas é que, na tela de informações sobre a rede Wi-Fi conectada no momento, é possível visualizar qual o tipo dessa conexão sem fio (Wi-Fi 5, Wi-Fi 6 ou até o avançado Wi-Fi 7).

In theory, developing a spacecraft that will fly to Mars, insert itself into orbit around the red planet, and relay transmissions back and forth to large satellite dishes on Earth is a relatively straightforward proposition.
NASA's procurement of a "Mars Telecommunications Network" spacecraft, however, has turned out to be one of the most engrossing dramas of the year for the US space agency.
The agency finally reached a decision earlier this month, selecting Blue Origin to develop, launch, and operate a $700 million spacecraft at Mars. However, the main competitor for the award, Rocket Lab, was not happy—at all. On Friday, the company filed a protest of NASA's decision with the US Government Accountability Office.

Apple in China occupies a position unlike the company’s presence in any other country. China is simultaneously a major consumer market, a critical manufacturing center, an extensive developer economy and the home of Apple’s most determined hardware competitors.
That combination creates an opportunity few technology companies can ignore. China has hundreds of millions of affluent mobile users, a strong appetite for premium devices and a digital economy built around smartphones.
It also creates unusual complexity. Apple must compete with Huawei, Xiaomi, Oppo and Vivo while satisfying Chinese regulations, navigating tensions between Beijing and Washington and reducing its manufacturing dependence without damaging the supplier network that helped make the iPhone possible.
The latest market figures show why Apple cannot treat China as a business it has already lost. IDC estimated that Apple captured 18.1 percent of Chinese smartphone shipments during the second quarter of 2026, placing it second behind Huawei at 22.6 percent.
Apple’s shipments increased by 24.4 percent from the previous year even as the wider Chinese smartphone market contracted. The recovery demonstrated that Chinese demand for the iPhone remains substantial when product design, storage, performance and pricing align with consumer expectations.
The same figures also show why the position can never be considered secure. Huawei remains ahead, local brands respond quickly and a few percentage points can separate several major vendors.
Apple in China Still Has Room to Grow
China is already one of Apple’s largest markets, but its scale means that even established product categories contain room for expansion.
The country has a large premium smartphone segment, extensive 5G coverage and consumers accustomed to using mobile devices for communication, payments, shopping, entertainment, transport and work.
An iPhone purchase can also lead to AirPods, Apple Watch, iPad, Mac, iCloud storage and paid applications. The commercial opportunity is therefore larger than the initial handset transaction.
Apple’s strongest advantage is its integrated ecosystem. An iPhone can share passwords, photographs, messages and files with a Mac or iPad, while AirPods and Apple Watch extend the experience without requiring separate accounts and setup systems.
That continuity becomes more valuable as households accumulate devices. Replacing one iPhone is relatively easy. Leaving an ecosystem containing several products, purchased applications, cloud storage and shared family services involves greater friction.
Apple also benefits from a premium identity that remains recognizable in China. Local manufacturers now produce sophisticated flagship phones, but the iPhone continues to operate as both a personal computer and a luxury consumer product.
The importance of that status should not be exaggerated. Chinese buyers are technically informed and increasingly willing to support domestic brands. Brand recognition can attract attention, but it does not excuse weak features or an uncompetitive product cycle.
Recent iPhone Demand Shows the Opportunity
Apple’s 2026 recovery offers a useful example of how quickly its position can improve.
China’s smartphone shipments fell 4.3 percent during the second quarter as memory and component costs pushed several manufacturers toward higher prices. Apple and Huawei held prices more stable, giving buyers a reason to purchase while competing brands became more expensive.
The iPhone 17 generation also addressed several areas where Apple’s standard models had appeared conservative beside Chinese flagships. Stronger base specifications made the regular iPhone more competitive without requiring every customer to move into the Pro tier.
This matters in a market where consumers compare display technology, camera systems, storage, battery life, charging and AI features closely. Apple cannot depend entirely on iOS loyalty when domestic companies introduce visible hardware improvements at several price levels.
The rebound does not establish a permanent trend. Smartphone demand in China remains affected by economic confidence, upgrade cycles, government incentives and the timing of major shopping festivals.
Apple’s position can also look different according to the research firm and whether a report measures shipments or consumer sales. Quarterly rankings should be treated as evidence of momentum rather than a final judgment on the market.
The important signal is that Chinese consumers have not broadly rejected the iPhone. Demand can return rapidly when the product and price create a convincing upgrade.
Huawei Makes China Apple’s Hardest Market
Huawei gives Apple a competitor with advantages unavailable to most global smartphone manufacturers.
The company combines strong national recognition with advanced cameras, communications technology, custom chips, local services and an expanding HarmonyOS ecosystem. Its return to premium smartphones removed the opening Apple had gained when U.S. restrictions disrupted Huawei’s access to important components.
Huawei can also position its products as part of China’s technological self-reliance. That message carries commercial and political weight beyond a conventional comparison between two phones.
Apple must therefore compete against product quality and national sentiment simultaneously. An iPhone can offer strong performance and still lose a purchase to a domestic flagship viewed as technically capable and strategically important.
Xiaomi, Oppo and Vivo add different pressures. They move quickly across price categories, experiment with folding designs, adopt larger batteries and provide features adapted to local applications and buying habits.
Chinese phone makers also operate inside a retail and software environment they understand directly. They can build relationships with local platforms, carriers and commerce services without translating a global strategy into Chinese requirements.
Apple follows a more centralized product model. That consistency protects the identity of the iPhone, but it can make the company slower to answer features gaining popularity inside one country.
Services Depend on Local Rules
Apple in China is not only an iPhone business. The installed device base creates demand for applications, cloud storage, entertainment, subscriptions and digital purchases.
China has an enormous developer community producing games, commerce platforms, social services, education tools and productivity software. The App Store connects those developers with high-value iPhone and iPad customers.
The relationship is commercially important but politically complicated. Apple must operate the mainland App Store according to Chinese law, including rules affecting games, generative AI, communications services and content.
Applications available elsewhere may be absent from the Chinese storefront. Developers may also need licenses or regulatory approval before distributing certain categories of software.
Apple changed commission rates and related policies for the mainland China storefront in March 2026. The company described the adjustments as part of maintaining a strong business opportunity for Chinese developers.
Regulatory and developer pressure has not disappeared. Complaints involving commissions, distribution restrictions and payment policies continue to challenge Apple’s control of the platform.
The company cannot simply copy its response from another region. European rules focus heavily on alternative marketplaces and interoperability, while China combines competition concerns with content regulation, data localization and licensing requirements.
Every concession must therefore be designed for a distinct legal environment without fragmenting iOS into an unmanageable collection of regional systems.
China Is Also Part of the Product
Apple’s relationship with China extends far beyond the devices sold there.
For more than two decades, Apple and its manufacturing partners built a dense network of factories, component suppliers, engineers, logistics operators and toolmakers across the country.
That network does more than provide low-cost labor. It can place specialists from several suppliers near an assembly site, modify production lines quickly and increase output to enormous volumes during a product launch.
China’s infrastructure also supports the less visible stages of manufacturing. Components require precision tooling, testing equipment, chemicals, packaging, subassemblies and experienced quality-control teams before final assembly begins.
Apple has expanded iPhone production in India and moved parts of its Mac, iPad, Apple Watch and AirPods supply chains to countries including Vietnam. It is also increasing semiconductor and component commitments in the United States.
Those investments reduce the danger of relying on one country, but they do not recreate China’s complete manufacturing environment immediately.
A factory in another region may assemble an iPhone while still depending on Chinese machinery, materials, subcomponents or engineering support. Production diversification is therefore a gradual redistribution of individual stages rather than a clean departure.
Apple must reduce concentration risk without weakening the manufacturing system responsible for its product quality, scale and launch schedules.

Trade Tensions Turn Efficiency Into Risk
The same China supply chain that provides Apple with extraordinary efficiency also exposes the company to political decisions outside its control.
Tariffs can raise the cost of devices exported from Chinese factories. Export restrictions can limit access to materials or production equipment, while sanctions may affect suppliers and technology partners.
Chinese government policies can influence the use of foreign devices inside state agencies and companies. U.S. rules can restrict the technologies available to Chinese firms that also participate in Apple’s supplier network.
Apple cannot solve these problems through product design alone. It must maintain relationships with two governments whose technology policies increasingly emphasize security, domestic production and strategic independence.
Moving more assembly to India gives Apple additional flexibility, particularly for iPhones destined for the United States. China nevertheless remains important as a production center and consumer market.
An aggressive withdrawal could damage supplier relationships and local sales. Moving too slowly could leave Apple vulnerable to another trade disruption.
The company is trying to preserve Chinese capabilities while creating enough capacity elsewhere to keep a political dispute from becoming a worldwide product shortage.
Retail Stores Give Apple a Direct Relationship
Apple’s physical stores remain an important advantage in China because they give the company direct contact with customers.
The stores allow buyers to compare models, receive technical support, attend educational sessions and enter the ecosystem without depending entirely on a carrier or reseller.
That experience is particularly valuable for premium products. A customer considering a Mac, Apple Vision Pro or high-end iPhone may need more explanation than someone replacing an inexpensive handset.
Retail locations also communicate long-term commitment. A prominent store represents more than a sales channel; it signals that Apple intends to remain part of the local technology market.
Online commerce is equally important. Chinese consumers are accustomed to large shopping festivals, aggressive promotions and rapid delivery through domestic platforms.
Apple must balance its controlled global pricing with a market where discounts can change quarterly rankings. Too little flexibility makes the iPhone appear expensive, while frequent reductions can train customers to delay purchases and weaken its premium image.
The strongest 2026 performance came partly from avoiding price increases while component costs were forcing rivals to reconsider their pricing. That advantage may disappear when competitors adjust their supply chains or launch another cycle of promotions.
Chinese Consumers Set a Higher Product Standard
China is often discussed as a sales problem for Apple, but it also functions as a demanding test of the iPhone.
Domestic flagship phones compete through larger batteries, rapid charging, advanced camera hardware, folding displays and deep integration with local digital services.
Features considered experimental elsewhere can become established expectations more quickly in China. Apple’s slower adoption cycle may look disciplined in one market and conservative in another.
The company must decide which expectations represent durable improvements and which are temporary specification contests. Copying every local feature would weaken Apple’s focused product strategy, but ignoring major changes creates openings for rivals.
This pressure can benefit Apple globally. Competition in China forces the company to defend the value of its standard iPhone, improve battery efficiency, strengthen cameras and make software features more useful outside English-speaking markets.
The opportunity is therefore not limited to selling more devices. China can reveal where Apple’s global assumptions no longer match the most competitive part of the smartphone industry.
Apple’s new AirTag (second generation), now with an expanded finding range and a louder speaker.
Apple’s second-generation AirTag is currently available at its lowest price ever: $89 for a four-pack, down from the usual $99. The deal matches the previous all-time low first spotted during Amazon’s Prime Day event and remains one of the strongest discounts on the newer model.
A single AirTag 2 is also discounted to $27 (from $29). While that price isn’t quite as aggressive as some earlier promotions, it still ranks among the better current offers for buyers who only need one unit.
The AirTag 2 is a compact Bluetooth tracker that helps users locate everyday items like keys, wallets, bags, or luggage through Apple’s Find My network, showing the last known location on a map and enabling Lost Mode to lock the tag and display a custom contact message via NFC when found by someone else.
AirTag 2 offers Precision Finding with a second-generation Ultra Wideband chip that provides directional arrows, distance readouts, and haptic/audio cues from up to 50% farther away (on compatible iPhone 15 or later models, excluding certain variants), plus the first-time ability to use this feature on Apple Watch Series 9 or later and Ultra 2 or later; an upgraded Bluetooth chip for expanded proximity range; a 50% louder speaker with a distinctive new chime that can be heard from twice as far; “Left Behind” alerts; sharing location access with family or friends; temporary secure sharing with airlines for luggage recovery; a user-replaceable CR2032 battery lasting over a year; IP67 water and dust resistance; and built-in privacy protections including frequent Bluetooth ID rotation and end-to-end encryption so only the owner can access location data.

A fast-moving wildfire, one of many raging across Spain, bore down on the Madrid Deep Space Communications Complex on Friday, forcing an evacuation and temporarily suspending operations at one of NASA's most important tracking stations.
The tracking station is part of NASA's Deep Space Network, operating in concert with similar facilities in California and Australia to provide global coverage as Earth's rotation brings the planets, stars, and deep space probes in and out of view. The network supports more than 40 missions from the Moon to the edge of the Solar System, including Artemis, the James Webb Space Telescope, and NASA's twin Voyager spacecraft.
A NASA spokesperson confirmed the tracking station in Spain, located in the hills nearly 40 miles (65 kilometers) west of central Madrid, was evaluated Friday "due to ongoing wildfires in the region. Photos and video from the area showed flames and smoke plumes rising over the ground station's antenna array, anchored by a 230-foot-diameter (70-meter) radio dish and a collection of smaller 112-foot (34-meter) antennas.

Call forwarding on iPhone is a simple feature with a specific job: it sends incoming calls from your iPhone number to another phone number. That can be useful when you are traveling, using a temporary phone, separating work and personal calls, covering a business line or making sure important calls reach someone else when you cannot answer.
The feature is built into iOS, but it depends on carrier support. Apple notes that call forwarding can be set up on iPhone if cellular service is through a GSM network. If the service uses a CDMA network, users may need to contact the carrier for setup details. That means the option may not appear for every user, every carrier or every plan.
For most supported iPhones, the path is quick:
Settings > Apps > Phone > Call Forwarding
Turn on Call Forwarding, then enter the phone number where calls should be sent. When call forwarding is active, an icon appears in the status bar so the user can see that incoming calls are being routed elsewhere.

Call Forwarding on iPhone Sends Calls Elsewhere
Call forwarding on iPhone does not move messages, FaceTime calls, app notifications or voicemail settings by itself. It only redirects standard cellular phone calls. If someone calls your iPhone number, the carrier routes that call to the number you entered.
That distinction is important. If you forward calls to another phone, text messages still arrive on the original iPhone unless other settings or services are involved. FaceTime calls may still ring on Apple devices signed into the same Apple Account. Messaging apps such as WhatsApp, Signal, Telegram or Messenger are unaffected.
Call forwarding is also different from Silence Unknown Callers, Focus modes or Do Not Disturb. Those features control how calls appear or interrupt you. Call forwarding changes where the call goes.
This makes the feature useful in a few common situations. A business owner can send calls to an office line. A traveler can forward calls to a local number. Someone with a damaged iPhone can temporarily send calls to another device. A freelancer can route calls to a partner during time off. A parent can forward calls to a spouse for a short period.
How to Turn On Call Forwarding
To turn on call forwarding:
Settings > Apps > Phone > Call Forwarding
Turn on Call Forwarding
Tap Forward To
Enter the phone number
Go back to save the setting
Use the full phone number, including area code. If forwarding to an international number, include the correct country code. After setting it up, test the feature from another phone. Do not assume it works until a test call rings at the forwarded number.
To turn call forwarding off:
Settings > Apps > Phone > Call Forwarding >Turn off
After turning it off, test again. A quick call from another phone confirms whether incoming calls are back to normal.
If the Call Forwarding menu spins, fails to load or does not save the number, restart the iPhone and check cellular service. If the problem continues, contact the carrier because the setting depends on the carrier network.
Why the Setting May Be Missing
Some users look for call forwarding and cannot find it. That usually means one of three things: the carrier does not expose the feature in iPhone settings, the plan does not support it, or the network requires carrier codes or account-level setup.
Apple’s guide says CDMA users should contact their carrier for call forwarding information. Some carriers also use special dialing codes for forwarding all calls, forwarding when busy, forwarding when unanswered or forwarding when unreachable. Those codes vary by carrier and country, so guessing is not a good idea.
The best path is to check the carrier’s support page or app. Many carriers let users manage forwarding from the account dashboard, especially for business lines or multi-line plans.
If the option is missing, the iPhone is not necessarily broken. The carrier may simply handle forwarding differently.
What Happens to Voicemail
Call forwarding can affect voicemail behavior depending on the carrier and destination number. If the forwarded phone does not answer, the call may go to the voicemail of the forwarded number instead of the original iPhone voicemail. In some cases, carrier rules may still send it back to the original mailbox, but users should not assume that.
This is another reason to test. Call the iPhone from another number, let it ring, and see where the missed call lands. If the goal is to preserve the original iPhone voicemail, carrier support may be needed.
For work numbers, this can be especially important. A forwarded business call going to a personal voicemail greeting can look unprofessional. A personal call going to a shared office voicemail can create privacy problems. Check before relying on it.

Call Forwarding and Dual SIM
iPhone users with Dual SIM or eSIM setups should pay attention to which line is being forwarded. A personal line and business line can have separate carrier settings. Forwarding one does not automatically forward the other.
To check lines:
Settings > Cellular >Select the line you want to manage
Then return to:
Settings > Apps > Phone > Call Forwarding
The available settings may vary by carrier and line. If one line supports call forwarding and the other does not, that is usually a carrier difference, not an iPhone problem.
Dual SIM users should also test both numbers separately. Call the personal number, then call the business number, and confirm each behaves as expected.
When Call Forwarding Is Useful
Call forwarding works best when the goal is temporary coverage. It is useful during travel, device repairs, vacations, business handoffs, office moves, event coverage or times when another person needs to answer calls.
It can also help people who use a landline or desk phone during work hours. Calls can be forwarded from the iPhone to the office line, then turned off at the end of the day. The reverse can also work if the carrier supports it.
For small businesses, call forwarding can help avoid missed calls without adding a full phone system. A company can route calls to whoever is available. For individuals, it can be a quick fix when an iPhone battery is failing, a device is being repaired, or cellular reception is better on another phone.
The feature is less ideal as a permanent business phone solution. If multiple people need to answer calls, if calls need menus, if calls need recordings, or if voicemail needs to stay organized, a dedicated phone service may be better.
Privacy and Cost Considerations
Call forwarding may create charges depending on the carrier, plan and destination number. Forwarding calls to an international number can be expensive. Forwarding to another domestic mobile number is usually simpler, but users should still check the plan.
Privacy also deserves attention. Once calls are forwarded, the person or device receiving them may hear personal, business or sensitive conversations meant for the original number. Do not forward calls to a shared phone unless that is intentional.
Before forwarding a work line to a personal number, check company policy. Some organizations do not allow business calls to be routed to unmanaged personal devices.

How to Troubleshoot Call Forwarding
If call forwarding does not work, start with the basics. Confirm the iPhone has cellular service. Restart the device. Check that the forwarding number is entered correctly. Turn call forwarding off, wait a few seconds, then turn it on again.
Then test from another phone. A test call is the fastest way to know whether the carrier accepted the setting.
If calls still do not forward, check whether the carrier supports call forwarding through iPhone settings. Some carriers require account-level activation, carrier codes or a business calling feature. If the iPhone setting is missing or stuck, carrier support is usually the right next step.
Also check Focus modes and blocked numbers if the issue is not forwarding but missed calls. A call may fail to ring because of Focus, Silence Unknown Callers, a blocked contact, poor signal or voicemail settings rather than call forwarding.
A Simple Feature Worth Testing
Call forwarding on iPhone is easy to use when the carrier supports it. Open iPhone settings, turn on Call Forwarding, enter the destination number and test it. Turn it off when the temporary need is over.
The feature is most useful when it is deliberate and short-term. It can keep calls moving during travel, repairs, work coverage or busy periods, but it should be checked carefully because voicemail, costs and privacy can change once calls are routed to another number.
The iPhone makes the setting simple. The carrier decides how far that simplicity goes.
A newly published study in Nature Metabolism reports that brown fat can act as a hub of molecular messaging, using secreted microRNAs to coordinate physiology across the body. Researchers focused on brown adipose tissue—well known for its role in thermogenesis—and asked whether it also participates in long-distance communication via RNA signals.
To visualize and track these messages, the team employed brown-fat–specific RNA labeling in living systems. This strategy allowed them to connect RNA production within adipocytes to downstream effects elsewhere, moving beyond correlations toward a clearer map of inter-organ RNA traffic.
The central finding is the presence of a communication network mediated by microRNAs released from brown fat. These small regulatory RNAs appear to travel beyond the tissue of origin and engage gene-regulatory pathways in other organs, effectively relaying information about metabolic state.
Functionally, the work supports a model in which microRNA “dispatch” from thermogenic fat tunes cellular programs in remote targets. Such programs likely involve post-transcriptional regulation, a process microRNAs are known to influence by pairing with complementary sequences in messenger RNAs.
Importantly, the approach does not treat microRNAs as generic circulating molecules. Instead, the labeling confirms their brown-fat origin and strengthens the link between secretory RNA dynamics and systemic physiological outcomes.
The study also highlights the specificity of the messaging: not all RNAs are equally represented, and the labeled microRNA repertoire points to organized, tissue-defined signaling rather than random leakage.
Beyond mapping pathways, the results carry implications for metabolic disease research. If brown fat microRNAs can reshape gene expression in other organs, manipulating these signals could offer a route to modulate energy balance, insulin sensitivity, or inflammatory tone.
For now, the findings provide a blueprint for how RNA labelling combined with tissue specificity can uncover hidden layers of endocrine-like communication. As techniques improve, the field may move toward a broader “RNA connectome” linking organ behavior through secreted regulatory molecules.
Researchers describe their results as evidence that brown fat is not only a metabolic engine but also an information broadcaster. In the evolving landscape of viral-style science news, this discovery underscores how tiny RNA molecules can orchestrate large-scale biological conversations.

Neuroscientists have long believed that language processing was only found in regions of the brain’s left hemisphere, including the well-known Broca’s area. However, new evidence suggests the brain’s language network is far more widespread than previously thought.
Researchers at the Massachusetts Institute of Technology (MIT) analyzed functional magnetic resonance imaging (fMRI) scans from 772 participants and identified 17 additional brain regions involved in language comprehension. These newly discovered areas are distributed across the brain, including the cerebellum, hippocampus, amygdala, and several regions of the cerebral cortex. In total, this accounts for five percent of the adult brain volume (roughly the size of a large strawberry).
“Even though there are all these distant components, it’s pretty restricted in terms of volume. You don’t need that much of the brain to do language,” says senior author Evelina Fedorenko, an MIT associate professor of brain and cognitive sciences and a member of MIT’s McGovern Institute for Brain Research, in a statement.
Locating the Brain’s Hidden Language Centers
To find these hidden language-related regions in the brain, the researchers revisited years of brain imaging data collected since 2013. Additionally, participants completed a standard “language localizer” task, during which they read or listened to meaningful sentences and sequences of meaningless nonwords. By comparing brain activity between these two conditions, the research team identified regions that responded more strongly to language.
“When we initially started looking at language, in the first couple of papers, I tried to be comprehensive and include anything that seemed consistent across participants, and there was a huge amount of resistance,” said Fedorenko. “People would say things like, ‘Well, we know those are not language areas, so please focus on the language areas.’”
The team decided to adopt a more flexible statistical approach to detect weaker signals and identify previously overlooked language-sensitive regions beyond the classical language areas. They then compared these regions’ responses during a spatial working memory task to distinguish language-specific areas from those involved in what would be considered general cognitive functions.
Cerebellum Discoveries
Interestingly, five of the newly identified language regions are located in the cerebellum, a structure traditionally associated with movement and coordination. Some of these cerebellar regions were also active during non-language tasks, suggesting they may help integrate information across different brain systems rather than process language alone.
“It’s a very simple paradigm that lets you identify this core language system in individual brains,” says MIT postdoc Agata Wolna, the lead author of the paper.
Additional language-sensitive regions were identified in the hippocampus and amygdala, areas better known for their roles in memory and emotion. Their involvement suggests that understanding language may rely more on integrating memory, emotional context, and higher-order cognitive functions than previously understood in science.
“We always see this frontal temporal network, but there’s quite a lot of evidence that there are other regions that are also critical for language processing,” said Wolna. “By using a laxer threshold and zooming in on areas with weak MRI signal, we tried to maximize the chances of finding small and weakly responsive regions outside of this left frontal temporal system.”
The findings challenge long-held assumptions about the brain’s organization and can open new avenues for research into how language processing is understood in neuroscience.
