Apple Watch Series 10 was introduced last year with a refreshed design. But when it comes to health sensors, Series 10 has pretty much the same capabilities as Series 9. Interestingly, a leaked prototype of Series 10 has just revealed that Apple may have had bigger plans for last years Apple Watch.Apple Watch Series 10 prototype hints at new health sensorsThe Apple leaker and collector known as StellaFudge has shared images of an intriguing prototype of the Apple Watch Series 10. Thats because this particular prototype has a very unique health sensor arrangement that differs not only from the sensors included in the final version of the Series 10, but from any other Apple Watch ever released.According to the leaker, the heart rate and blood oxygen level sensors in this prototype are much smaller than in the sensor that Apple currently uses. But thats not all, as the back of the leaked Apple Watch Series 10 prototype also includes a never-before-seen extra light ring between the ECG sensor and the heart rate sensors.According to rumors, Apple has been working on blood pressure and blood glucose sensors for the Apple Watch. The company would have experimented with these new sensors during the prototyping phase of the Series 10, but ended up delaying them to focus on the new design. The leaker believes that the prototype was used for internal testing with the new health sensors.Unfortunately, although the prototype is fully functional, it runs an internal build of watchOS 11.1 without the stock apps installed (because they can only be downloaded through Apples internal network). For this reason, theres no way to explore whether the health apps on this Apple Watch Series 10 prototype have any new unreleased features.Another interesting detail is that the internal build installed on this prototype dates back to October 2024, which suggests that Apple is still running experiments with these new health sensors. Maybe well finally see them in action on the next generation Apple Watch.Gadgets I recommend:Add 9to5Mac to your Google News feed. FTC: We use income earning auto affiliate links.

iOS 18.4 is here, bringing with it a ton of new features. One of my favorites? A new Apple Music capability that expands the services reach beyond the Music app, pushing further into Control Center and more.Ambient Music controls expand Apple Musics reach in iOS 18.4After you install iOS 18.4, if youre like me youll probably pop into some of your favorite apps to see if anythings changed.Doing this with the Music app will reveal no discernible new features. But thats because the latest Apple Music feature isnt found directly inside the app.Instead, Apple has done something unique and expanded Apple Musics functionality into a new set of Ambient Music controls in iOS 18.4. Essentially, the update adds special new ways to trigger Apple Music mood playlists from outside the Music app.iOS 18.4 supports four such moods, though I wouldnt be surprised if more arrive in future updates.SleepChillProductivityWellbeingEach control has been assigned to play a specific Apple Music playlist. For example, by default the Productivity control plays BEATstrumentals, but you can also select one of three other curated playlists, or set it to trigger any playlist of your choice.You can assign these new music controls to any of the following three places:Control Centeryour Lock Screenand the iPhones Action buttonTo update a controls playlist setting, be sure youre in editing mode then tap the control and youll see customization options.Apple Music in iOS 18.4: wrap-upOpening the Music app will continue being the main way most of us interact with Apple Music, but I love what Apples doing with iOS 18.4s new Ambient Music controls. The ability to assign a mood playlist button to your iPhones Lock Screen, Action button, or Control Center removes friction from the music playback experience. It also helps reduce my own analysis paralysis when opening the Music app and confronting far too many options to choose from. Now I can have a simple toggle fit for these select occasions.What do you think of the ambient music options Apple added to iOS 18.4?

Jared Isaacman, the billionaire fighter jet pilot-turned-SpaceX astronaut, has shared a photo of himself during his unusual "commute into DC" which involved a Cessna CJ4 private jet.The entrepreneur, who is estimated to be worth $1.9 billion, was tapped late last year by president Donald Trump to lead NASA, and he's chosen to head into the nation's capital to "meet with Senators this week"in a style that feels like a perfect illustration of the billionaires now running the government.That's likely in anticipation of being sworn in, a decision that has seemingly been delayed by several months now. In his absence, NASA's acting administrator Janet Petro has been cracking the whip, overseeing mass layoffs and a major clampdown on personal freedoms among employees, including the purging of any paraphernalia related to the LBGTQ movement.But as Ars Technica reported last week, momentum appears to be building for Isaacman to take over. That's despite senator Ted Cruz (R-TX) who chairs the Senate Committee on Commerce, Science, and Transportation, and is expected to reside over swearing-in procedures voicing some concerns.First and foremost, given Isaacman's extremely close proximity to SpaceX CEO and unelected White House hatchet man Elon Musk, concerns over NASA ditching its plans to return to the lunar surface in favor of visiting Mars first could lead to tensions during Isaacman's hearing.Isaacman has traveled to space twice during two all-private missions involving SpaceX's Crew Dragon capsules. This past August, he became the first-ever civilian to embark on a spacewalk.That kind of close association with Musk could end up being a major hindrance or a carte blanche. Musk has gained a tremendous amount of influence over the federal government's budget allocations through his so-called Department of Government Efficiency, including at NASA.In fact, recent reporting suggests that he andhis space firm are looking to assume control over much of what's left of the space agency.Isaacman himself has largely stayed out of the limelight and his own stance on critical matters, perhaps most notably NASA's plans to return to the Moon, remains unclear at best.His relationship with SpaceX, however, could prove a sticking point.In a March 12 letter to NASA's chief legal officer Iris Lan, he argued that any possible conflicts of interest wouldn't be an issue."In the event that an actual or potential conflict of interest arises during my appointment, I will consult with an agency ethics official and take the measures necessary to resolve the conflict, such as recusal from the particular matter or divestiture of an asset," he wrote.Whether that will be enough to appease Congress remains to be seen.However, as Ars reports, the space travel community appears to have his back. A group of more than two dozen former astronauts sent Cruz a letter in support of Isaacman, arguing that he's "uniquely qualified to lead NASA at the critical juncture."How all of this will play out is anybody's guess. Morale at the space agency is at historically low levels given its plundering by the Trump administration. Workers were given far less notice of their impending firing than contractually agreed upon and were even denied time-off awards.That kind of callous treatment had many employees furious."Everybodys lost confidence," one employee who remains at the agency told CNN. "What was the urgency? It just seems cruel."In short, it'd be an understatement to say that Isaacman has a lot of fires to put out. Questions surrounding his close relationship with SpaceX are bound to come up especially if NASA does decide to nix its Moon program to fulfill Musk's personal wish to send astronauts to Mars.According to Ars senior reporter Eric Berger, chances are we'll hear more about Isaacman's swearing-in soon."One-on-one meetings with US senators are a precursor to a committee hearing for Isaacman to become NASA administrator," he tweeted in response to Isaacman's latest post. "The timeline is not firm, but such a hearing could come in late April, with confirmation in May."More on Isaacman: Incoming NASA Administrator Brags That He Has No Idea What's Going OnShare This Article

We've never seen a rocket explode with this kind of view before.Arctic BlastA rocket by German startup Isar Aerospace tore into the sky over Norway's Arctic Andoeya Spaceport, a European launch base for small satellites, over the weekend only to plummet back down to the ground, exploding in a dramatic fireball.Fortunately, while the spaceport's "crisis management" was triggered, nobody was hurt.As Reuters reports, the rocket, dubbed Spectrum, was meant to kick off Europe's efforts to keep up with steep international competition when it comes to launching satellites into orbit. The company says it's the first rocket designed for orbital flight that has ever been launched from continental Europe, excluding Russia.Elon Musk's SpaceX, in particular, has made major headwinds in establishing a massive constellation of Starlink satellites."Europe urgently needs to ensure its sovereignty in space," said Marie-Christine von Hahn, managing director of Germany's BDLI aerospace industries association, in a statement, as quoted by Reuters. "Elon Musk's Starlink is not without alternatives nor should it be."Launch, Rinse, RepeatWhile the launch may have resulted in an epic fireball in glorious footage of a rocket exploding in front of gorgeous, snow-covered mountains Isar Aerospace claims it was an important step in the right direction."With this test flight, we were able to successfully gather valuable data and experience for future missions," the company tweeted. "Thanks to strict safety procedures from both Isar Aerospace and Andya Spaceport, all personnel remained safe at all times.""Isar Aerospace met its set goals: After ignition of its first stage, Spectrum successfully lifted off," the company wrote in a statement, "for its first test flight lasting approximately 30 seconds. This allowed the company to gather a substantial amount of flight data and experience to apply on future missions."It's a particularly noteworthy development, given Europe's broader goals of reducing its dependence on the United States, particularly when it comes to security."We will be able to serve customers from around the world to bring their satellites into space and to help Europe solve a major blind spot in its security architecture: access to space," said Isar Aerospace CEO and cofounder Daniel Metzler in a statement."Launch, learn, repeat," the company wrote, echoing SpaceX's iterative design methodology.Share This Article

March 31, 20253 min readAs Measles Continues to Rise, CDC Muffles Vaccine MessagingBy burying an assessment with updates and recommendations about the U.S.s current measles outbreaks, the CDC has signaled an alarming shift in its public messagingBy Jen Schwartz edited by Jeanna BrynerA health worker prepares a dose of the measles vaccine at a health center in Lubbock, Texas, on February 27, 2025. Ronaldo Schemidt/AFP via Getty ImagesAs measles outbreaks have continued to spread in 19 U.S. states, leaders at the Centers for Disease Control and Prevention have buried a new assessment by their own experts that found there is a high risk of catching measles in areas where vaccination rates are low, according to an article published by ProPublica on March 28. The assessment had also called for a messaging strategy to encourage vaccination against the potentially deadly disease. But that plan was aborted, signaling a shift in how the agency may be responding to pressure from vaccine critic Robert F. Kennedy, Jr., who is now secretary of health and human services.Why It MattersMeasles, caused by a highly contagious and dangerous virus, is very effectively prevented by the measles-mumps-rubella (MMR) vaccine. But rates of vaccination in the U.S. have been declining in recent years. Historically, the CDCs messaging strategy for encouraging vaccination emphasized the importance of protecting both oneself and the community at large, especially vulnerable people who cannot yet get vaccinated such as young babies. Whats alarming about the CDCs recent inaction is not just its decision to bury the news, health experts say, but also the agencys justification for doing so: in a statement to ProPublica, a CDC spokesperson wrote, The decision to vaccinate is a personal one, a message that does not reflect long-standing scientific consensus but rather echoes the sentiment of vaccine critics such as Kennedy.On supporting science journalismIf you're enjoying this article, consider supporting our award-winning journalism by subscribing. By purchasing a subscription you are helping to ensure the future of impactful stories about the discoveries and ideas shaping our world today.Why Vaccine Skepticism Remains a Big ProblemVaccines, especially the MMR vaccine, have been a target of rampant misinformation in recent years. A single fraudulent study had claimed a connection between the MMR vaccine and autism, but that link was debunked years ago. Many other studies have searched for a connection and failed to find one. But lack of trust in vaccine safety remains a big public health issue: A recent survey conducted by the University of Pennsylvania found that the percentage of people who believed that already-approved vaccines were unsafe jumped from 9 percent all the way up to 16 percent between 2021 and 2023. Measles was declared eliminated from the U.S. in 2000, which means it does not circulate on its own. But outbreaks are becoming more common. The total number of people who have tested positive for measles so far this year is already higher than any full year since 2019.What This means for the CDC and Public Health MessagingPublic health officials learned a lot from the COVID pandemic. Chief among those lessons was that frequent and transparent communication is key to establishing and maintaining trust with the public, say public health educators. Withholding essential updates and best practices undermines those goals. It can also prevent data and guidance from reaching local public health services in a timely manner.What You Can Do to Protect YourselfIf youre an adult who was vaccinated against MMR as a child, you can check to see if youre still protected with a simple blood test. If you were born between 1957 and 1975, you likely only got one dose of the vaccine instead of the standard two doses that are given today. The second dose boosts the efficacy of the vaccines protection against measles from 93 percent to 97 percent. If you had only received one dose and live in an area where an outbreak is occurring or work in certain environments such as health care facilities, you might want to talk to your health care provider about your risk and consider an additional dose.

Monster Hunter Wilds performance-related PC improvements coming this week, says CapcomAs future plans detailed.Image credit: Eurogamer/Capcom News by Matt Wales News Reporter Published on March 31, 2025 Monster Hunter Wilds has been an massive success for publisher Capcom, but not everybody's happy on PC, where the game has been repeatedly lambasted for its poor performance. Finally, however, a month after its release, Capcom has revealed a first round of performance-related PC improvements is coming later this week.Capcom shared the news in a lengthy post from Monster Hunter Wilds game director Yuya Tokuda over on the official Monster Hunter website. After thanking players for their support amid Wilds' impressive 10m sales milestone, Tokuda began detailing some of the improvements the developer is targeting in response to player feedback.The big one, for PC players at least, is the promise of improved game stability. "The team is continuing to identify stability issues and make improvements where possible," Tokuda wrote, "especially on the Steam version. This will be an ongoing process, where we'll aim to make continual steps forward in this area and respond to critical issues."Here's Alex with the full lowdown on Monster Hunter Wilds' PC release.Watch on YouTubeThe good news is Capcom's first round of performance-related PC improvements is set to arrive very soon - as part of Monster Hunter Wilds' Title Update 1 this Thursday, 3rd April. This'll include a promised reduction in VRAM usage, as well as an upgrade to the DirectStorage version on Steam - both of which "should result in an overall improvement in stability for our PC players", according to Capcom.Notably, VRAM usage and DirectStorage issues were both highlighted in Digital Foundry's review of Monster Hunter Wilds on PC, in which Alex Battaglia detailed the games "profound performance problems" and "substantial" technical issues. At the time, Alex advised "caution" for higher-end GPU owners, but flat-out recommended anyone with lower-end graphics cards "avoid" Wilds until Capcom could improve the situation - so hopefully this week's update will bring meaningful changes ahead of promised "continued improvements" in future patches.Away from PC performance, Tokuda highlighted some other areas the team is targeting. There's talk of weapon balance adjustments, for instance, which are set to be implemented "gradually" with each new title update. As for quality of life changes, Capcom says it's currently looking to make it easier for players to access information they require through UI/UX improvements, alongside "additional adjustments... to further enhance the overall feel of the game to curate an even smoother gameplay experience."Capcom says to expect changes making it easier to restock items, check skill information, participate in multiplayer quests, and use the Seikret. Additionally, improved camera behaviour during hunts is also on the developer's to-do list. More generally, the team is planning to "take a wider look at overall gameplay flow, which encompasses a range of things, such as the in-game economy, balance and other areas." This, it says, will "require more time for preparation".Alongside the aforementioned PC performance improvements, this week's Monster Hunter Wilds title update introduces a new social hub and a range of new monsters, including bubble dragon Mizutsune, a High Rank version of Zoh Shia, and the arch-tempered Rey Dau. Notably, Tokuda's blog stresses additional tough monsters are on the way, following criticism of Wilds' low difficulty at launch. May's update, for instance - which previously appeared to be relatively small in scope - will bring tempered variants of Gore Magala, Rey Dau, Uth Duna, Nu Udra, and Jin Dahaad. Additionally, more "challenging monsters will also appear in future updates"."We will continue to add new elements and content to make Monster Hunter Wilds even more enjoyable for all hunters through our free content updates," Tokuda concluded, "while at the same time making further improvements and adjustments to the game."
