Asteroid 2024 YR4 Has a 4% Chance of Hitting the Moon

An anonymous reader quotes a report from Universe Today: There’s a bright side to every situation. In 2032, the Moon itself might have a particularly bright side if it is blasted by a 60-meter-wide asteroid. The chances of such an event are still relatively small (only around 4%), but non-negligible. And scientists are starting to prepare both for the bad (massive risks to satellites and huge meteors raining down on a large portion of the planet) and the good (a once in a lifetime chance to study the geology, seismology, and chemical makeup of our nearest neighbor). A new paper from Yifan He of Tsinghua University and co-authors, released in pre-print form on arXiv, looks at the bright side of all of the potential interesting science we can do if a collision does, indeed, happen. If Asteroid 2024 YR4 were to hit the Moon, researchers would be able to watch a large lunar impact unfold in real time and collect data on extreme collisions that usually exist only in computer models. Telescopes could follow how a newly formed crater and its pool of molten rock cool and solidify, while the resulting moonquake would offer a clearer picture of its internal structure via the seismic waves it sends through the Moon.

Furthermore, researchers could compare the fresh crater to older ones to improve our understanding of the Moon’s long history of impacts. Debris blasted off the surface could even deliver small lunar samples to Earth.

Altogether, it would be a once-in-a-generation chance to learn more about how the Moon/rocky worlds respond to powerful impacts.

Ancient Martian Beach Discovered, Providing New Clues To Planet’s Habitability

alternative_right shares a report from Phys.org: New findings from NASA’s Perseverance rover have revealed evidence of wave-formed beaches and rocks altered by subsurface water in a Martian crater that once held a vast lake — considerably expanding the timeline for potential habitability at this ancient site. In an international study led by Imperial College London, researchers uncovered that the so-called ‘Margin unit’ in Mars’s Jezero crater preserves evidence of extensive underground interactions between rock and water, as well as the first definitive traces of an ancient shoreline.

These are compelling indicators that habitable, surface water conditions persisted in the crater (home to a large lake around 3.5 billion years ago) further back in time than previously thought. “Shorelines are habitable environments on Earth, and the carbonate minerals that form here can naturally seal in and preserve information about the ancient environment,” said lead author Alex Jones, a Ph.D. researcher in the Department of Earth Science and Engineering (ESE) at Imperial. The findings have been published in the Journal of Geophysical Research: Planets.

Amazon Inadvertently Announces Cloud Unit Layoffs In Email To Employees

Amazon appears to have prematurely acknowledged layoffs inside AWS after an internal email referencing “organizational changes” and “impacted colleagues” was mistakenly sent to cloud employees. CNBC reports: “Changes like this are hard on everyone,” Colleen Aubrey, senior vice president of applied AI solutions at Amazon Web Services, wrote in an email viewed by CNBC. “These decisions are difficult and are made thoughtfully as we position our organization and AWS for future success.” The note also references a post from Amazon’s HR boss Beth Galetti and said the company notified “impacted colleagues in our organization.” The subject of the email mentions “Project Dawn,” and the email says it was “canceled,” possibly indicating it was recalled by the sender after the fact. It’s unclear what Project Dawn refers to.

The job cuts come after Amazon announced in October that it would lay off 14,000 corporate employees. At the time, the company indicated the cuts would continue in 2026 as it found “additional places we can remove layers.” Amazon CEO Andy Jassy said the layoffs were meant to reduce management layers and bureaucracy inside the company. He also predicted last June that efficiency gains from AI would shrink Amazon’s corporate staff in the coming years.

US Government Lost More Than 10,000 STEM PhDs Last Year

An anonymous reader quotes a report from Science.org: Some 10,109 doctoral-trained experts in science and related fields left their jobs last year as President Donald Trump dramatically shrank the overall federal workforce. That exodus was only 3% of the 335,192 federal workers who exited last year but represents 14% of the total number of Ph.D.s in science, technology, engineering, and math (STEM) or health fields employed at the end of 2024 as then-President Joe Biden prepared to leave office. The numbers come from employment data posted earlier this month by the White House Office of Personnel Management (OPM). At 14 research agencies Science examined in detail, departures outnumbered new hires last year by a ratio of 11 to one, resulting in a net loss of 4224 STEM Ph.D.s. The graphs that follow show the impact is particularly striking at such scientist-rich agencies as the National Science Foundation (NSF). But across the government, these departing Ph.D.s took with them a wealth of subject matter expertise and knowledge about how the agencies operate.

[…] Science’s analysis found that reductions in force, or RIFs, accounted for relatively few departures in 2025. Only at the Centers for Disease Control and Prevention, where 16% of the 519 STEM Ph.D.s who left last year got pink RIF slips, did the percentage exceed 6%, and some agencies reported no STEM Ph.D. RIFs in 2025. At most agencies, the most common reasons for departures were retirements and quitting. Although OPM classifies many of these as voluntary, outside forces including the fear of being fired, the lure of buyout offers, or a profound disagreement with Trump policies, likely influenced many decisions to leave. Many Ph.D.s departed because their position was terminated.

Apple Updates iOS 12 For the First Time Since 2023

Apple quietly released its first update to iOS 12 since 2023 to keep iMessage, FaceTime, and device activation working on older hardware through January 2027. The update applies to legacy devices like the iPhone 5S, iPhone 6/6 Plus, and 2013-era iPads. Macworld reports: The update appears to be related to a specific issue. According to Apple’s “About iOS 12 Updates” page, iOS 12.5.78 “extends the certificate required by features such as iMessage, FaceTime, and device activation to continue working after January 2027.” Meanwhile, the iOS 16 update says it “provides important bug fixes and is recommended for all users.”

When iOS 13 arrived, it dropped compatibility for the iPhone 5S, iPhone 6, and iPhone 6 Plus, as well as the 2013 iPad Air and iPad Mini 3, so users of those phones should specifically take note. To update to the latest version, head over to the Settings app, then General and Software Update, and follow the instructions.

Apple M3 Progress On Linux: Asahi Can Boot To KDE Desktop – But No GPU Acceleration Yet

While the Asahi Linux project has made good progress on bringing Linux to Apple Silicon hardware, much of the success and in turn upstreaming to the Linux kernel has been around the aging M1 and M2 Macs. Apple M3 and newer has been a struggle but progress is being made. One of the Asahi Linux developers shared the ability now to boot to the KDE Plasma desktop with the experimental Asahi Linux code on an M3 MacBook but without any GPU acceleration yet…

Scientists Launch AI DinoTracker App That Identifies Dinosaur Footprints

Scientists have released DinoTracker, a free AI-powered app that identifies dinosaur footprints by analyzing shape patterns rather than relying on potentially flawed historical labels. “When we find a dinosaur footprint, we try to do the Cinderella thing and find the foot that matches the slipper,” said Prof Steve Brusatte, a co-author of the work. “But it’s not so simple, because the shape of a dinosaur footprint depends not only on the shape of the dinosaur’s foot but also the type of sand or mud it was walking through, and the motion of its foot.” The Guardian reports: […] Brusatte, [Dr Gregor Hartmann, the first author of the new research from Helmholtz-Zentrum in Germany] and colleagues fed their AI system with 2,000 unlabelled footprint silhouettes. The system then determined how similar or different the imprints were from each other by analysing a range of features it identified as meaningful. The researchers discovered these eight features reflected variations in the imprints’ shapes, such as the spread of the toes, amount of ground contact and heel position. The team have turned the system into a free app called DinoTracker that allows users to upload the silhouette of a footprint, explore the seven other footprints most similar to it and manipulate the footprint to see how varying the eight features can affect which other footprints are deemed most similar. Hartmann said that at present experts had to double check if factors such as the material the footprints were made in, and their age, matched the scientific hypothesis, but the system clustered prints with those expected from classifications made by human experts about 90% of the time. The findings have been published in the journal PNAS.

SoundCloud Data Breach Impacts 29.8 Million Accounts

A data breach at SoundCloud exposed information tied to 29.8 million user accounts, according to Have I Been Pwned. While SoundCloud says no passwords or financial data were accessed, attackers mapped email addresses to public profile data and later attempted extortion. BleepingComputer reports: The company confirmed the breach on December 15, following widespread reports from users who were unable to access SoundCloud and saw 403 “Forbidden” errors when connecting via VPN. SoundCloud told BleepingComputer at the time that it had activated its incident response procedures after detecting unauthorized activity involving an ancillary service dashboard. “We understand that a purported threat actor group accessed certain limited data that we hold,” SoundCloud said. “We have completed an investigation into the data that was impacted, and no sensitive data (such as financial or password data) has been accessed. The data involved consisted only of email addresses and information already visible on public SoundCloud profiles.”

While SoundCloud didn’t provide further details regarding the incident, BleepingComputer learned that the breach affected 20% of all SoundCloud users, roughly 28 million accounts based on publicly reported user figures (SoundCloud later published a security notice confirming the information provided by BleepingComputer’s sources). After the breach, BleepingComputer also learned that the ShinyHunters extortion gang was responsible for the attack, with sources saying that the threat group was also attempting to extort SoundCloud. This was confirmed by SoundCloud in a January 15 update, which said the threat actors had “made demands and deployed email flooding tactics to harass users, employees, and partners.”

Dozens of CDC vaccination databases have been frozen under RFK Jr.

Nearly half of the databases that public health officials at the Centers for Disease Control and Prevention were updating on a monthly basis have been frozen without notice or explanation, according to a study published in the Annals of Internal Medicine.

The study—led by Janet Freilich, a law expert at Boston University, and Jeremy Jacobs, a medical professor at Vanderbilt University—examined the status of all CDC databases, finding a total of 82 that had, as of early 2025, been receiving updates at least monthly. But, of those 82, only 44 were still being regularly updated as of October 2025, with 38 (46 percent) having their updates paused without public notice or explanation.

Examining the databases’ content, it appeared that vaccination data was most affected by the stealth data freezes. Of the 38 outdated databases, 33 (87 percent) included data related to vaccination. In contrast, none of the 44 still-updated databases relate to vaccination. Other frozen databases included data on infectious disease burden, such as data on hospitalizations from respiratory syncytial virus (RSV).

TikTok users “absolutely justified” for fearing MAGA makeover, experts say

TikTok wants users to believe that errors blocking uploads of anti-ICE videos or direct messages mentioning Jeffrey Epstein are due to technical errors—not the platform seemingly shifting to censor content critical of Donald Trump after he hand-picked the US owners who took over the app last week.

However, experts say that TikTok users’ censorship fears are justified, whether the bugs are to blame or not.

Ioana Literat, an associate professor of technology, media, and learning at Teachers College, Columbia University, has studied TikTok’s politics since the app first shot to popularity in the US in 2018. She told Ars that “users’ fears are absolutely justified” and explained why the “bugs” explanation is “insufficient.”

LEGO x Crocs Giant Stud Slides

Because it was only a matter of time before some LEGO exec made a joke during a meeting about stepping on LEGO bricks and a lightbulb went off in their head and they got on the horn to Crocs to make it happen, these are the LEGO x Crocs Brick Clogs. They’re Crocs that look like the lovechild of studded LEGO plates and clown shoes (what I wouldn’t have given to be a fly on the window of that clown car!). Available in red only in men’s sizes 5 – 13 (women’s 7 – 15), they’ll cost $150 when they’re released February 16th. Great, just in time for not Valentine’s Day. Now I’ll have to remember to get something else. Or, more likely, forget to get something else. The doghouse: I live in it. “Do you even have a girlfriend?” Not that I’ve seen since two Valentine’s Days ago.

Quest’s New ‘Navigator’ UI Becoming Default As Horizon Feed To Be Removed

“Starting” in Horizon OS v85, the new ‘Navigator’ UI will become the default, and Horizon Feed will be “gradually” removed from the OS.

In a Meta Community Forums post, a ‘Community Manager’ with the handle h.taylor announced the upcoming changes, set to arrive in the next version of the Horizon OS of Quest headsets:

As announced during Connect, we’ve been testing Navigator and will ramp up the rollout later this year, starting in v85. As Navigator rolls out, we’ll also begin gradually sunsetting the Horizon Feed in VR.

What’s changing

• Navigator will become the default landing experience when users turn on their headset.

• Navigator brings experiences, friends and settings together in one place.

• As part of this shift, we’ll be sunsetting the Horizon Feed in VR.

Horizon OS v83 started rolling out in November, and there’s no set date for the arrival of v85.

Navigator Becoming Default

Since the release of Oculus Go over seven years ago, Meta’s standalone VR operating system has seen numerous visual changes, but the general interface architecture remained essentially the same.

You had a floating horizontal menu bar slightly below you, called the Universal Menu, showing the time and your device battery levels and containing shortcuts to key system interfaces, as well as a combination of your most recent and eventually a few of your favorite apps. All 2D interfaces, including system features like the app Library, Quick Settings, and Notifications, opened as 2D windows, treated like any other.

After One Key Change, Meta’s Quest UI Overhaul Has Gone From Bad To Great
The Quest system UI overhaul launched to testers in May, with key improvements but an ugly semi-opaque grey “cloud” background. Now, Meta has gotten rid of it.
UploadVRDavid Heaney

Then, in May last year, Meta started a very slow rollout of a full Horizon OS UI overhaul, called ‘Navigator’, which moves the main system interfaces like Library, Quick Settings, Notifications and Camera into a new large overlay that appears over both immersive and 2D apps.

With Navigator, system interfaces no longer shift around when opening other windows, and it’s easier to launch new apps. Navigator’s library also allows you to pin up to 10 items, somewhat akin to the Start Menu on Windows.

At launch, Navigator also had a murky gray background with an oval shape. It was seemingly intended to improve contrast. But as well as obscuring your view of what was behind it, be it passthrough or a virtual world, it just didn’t look good. So Meta got rid of that and made bringing up Navigator dim the background instead.

Meta presenting the evolved Horizon OS Navigator UI.

With Horizon OS v83 PTC in October, Meta started rolling out an evolved version of Navigator, which it teased at Connect 2025.

The evolved Navigator has a new Worlds tab for Horizon Worlds destinations, and you no longer see worlds in your app Library at all. Speaking of the Library, it now features interleaving offset rows, similar to Apple’s visionOS.

The new Navigator also has a new overlay-level People tab with shortcuts to your friends, as well as a You tab that shows your avatar and lets you change your active status.

Finally, the new Navigator lets you easily hide or show all your 2D windows by double pressing the Meta button on the right Touch controller, or for hand tracking, opening your right palm and double tapping your thumb to your index finger.

Horizon Feed Being Removed

Horizon Feed is the default 2D app that launches when you cold boot your Quest headset.

Originally simply called ‘Explore’, the feed shows you suggested Horizon Worlds destinations, store apps, VR videos, Instagram reels, and online followers, as well as suggested friends to “catch up” with and apps to “jump back in” to.

Screenshot by UploadVR.

The Community Forums post tells developers that the version of Horizon Feed inside the headset “is not a high-intent surface, and users often see it without a specific intent to browse or purchase apps”.

“Because of that, it historically has not driven strong entitlement conversion, and we don’t expect significant revenue impact for the vast majority of developers”, the post reads.

That essentially seems to be Meta admitting that Horizon Feed is something that most Quest owners just close immediately on booting the headset, like an unwanted popup, and wasn’t successful at getting people to buy the apps that it suggested.

Meta CTO Explains Layoffs & Strategy Shift: “VR Is Growing Less Quickly Than We Hoped”
In a series of interviews at Davos, Meta CTO Andrew Bosworth explained why the company is reducing its investment in VR.

The coming removal of Horizon Feed from Horizon OS comes as Meta CTO Andrew Bosworth suggested that the company’s repeated push to Quest owners to use Horizon Worlds came at “an expense of user experience”, vowing to “let VR be what it is, what it does” and “focus a lot more on the third-party content library, the ecosystem that’s developed there”.

Amazon To Pay $309 Million To US Shoppers In Settlement Over Returns

Amazon has agreed to pay $309 million and provide additional remedies in a class-action settlement over claims that customers were wrongly denied refunds after returning items. Plaintiffs say (PDF) the deal delivers over $1 billion in total value, including more than $600 million in refunds and operational changes. Reuters reports: Amazon denied any wrongdoing in agreeing to the settlement. “Following an internal review in 2025, we identified a small subset of returns where we issued a refund without the payment completing, or where we could not verify that the correct item had been sent back to us, so no refund had been issued,” an Amazon spokesperson said, adding that the company had taken steps to resolve the issue.

The lawsuit, filed in 2023, said Amazon caused “substantial unjustified monetary losses” for consumers who in some instances properly returned an item but were still charged for it. In a court filing, Amazon said customers accepted the terms of the company’s return policies, including the possibility they would be recharged for failing to return the product within a specified time frame. The proposed settlement class covers U.S. purchasers of goods on Amazon from September 2017 who allegedly did not receive timely or correct refunds, or who were later charged despite returning items. Class members are expected to recover the full amount of any incorrectly denied refund or retrocharge, plus interest, the plaintiffs told the court.

Internal Messages May Doom Meta At Social Media Addiction Trial

An anonymous reader quotes a report from Ars Technica: This week, the first high-profile lawsuit — considered a “bellwether” case that could set meaningful precedent in the hundreds of other complaints — goes to trial. That lawsuit documents the case of a 19-year-old, K.G.M, who hopes the jury will agree that Meta and YouTube caused psychological harm by designing features like infinite scroll and autoplay to push her down a path that she alleged triggered depression, anxiety, self-harm, and suicidality. TikTok and Snapchat were also targeted by the lawsuit, but both have settled. The Snapchat settlement came last week, while TikTok settled on Tuesday just hours before the trial started, Bloomberg reported. For now, YouTube and Meta remain in the fight. K.G.M. allegedly started watching YouTube when she was 6 years old and joined Instagram by age 11. She’s fighting to claim untold damages — including potentially punitive damages — to help her family recoup losses from her pain and suffering and to punish social media companies and deter them from promoting harmful features to kids. She also wants the court to require prominent safety warnings on platforms to help parents be aware of the risks. […]

To win, K.G.M.’s lawyers will need to “parcel out” how much harm is attributed to each platform, due to design features, not the content that was targeted to K.G.M., Clay Calvert, a technology policy expert and senior fellow at a think tank called the American Enterprise Institute, wrote. Internet law expert Eric Goldman told The Washington Post that detailing those harms will likely be K.G.M.’s biggest struggle, since social media addiction has yet to be legally recognized, and tracing who caused what harms may not be straightforward. However, Matthew Bergman, founder of the Social Media Victims Law Center and one of K.G.M.’s lawyers, told the Post that K.G.M. is prepared to put up this fight. “She is going to be able to explain in a very real sense what social media did to her over the course of her life and how in so many ways it robbed her of her childhood and her adolescence,” Bergman said.

The research is unclear on whether social media is harmful for kids or whether social media addiction exists, Tamar Mendelson, a professor at Johns Hopkins Bloomberg School of Public Health, told the Post. And so far, research only shows a correlation between Internet use and mental health, Mendelson noted, which could doom K.G.M.’s case and others.’ However, social media companies’ internal research might concern a jury, Bergman told the Post. On Monday, the Tech Oversight Project, a nonprofit working to rein in Big Tech, published a report analyzing recently unsealed documents in K.G.M.’s case that supposedly provide “smoking-gun evidence” that platforms “purposefully designed their social media products to addict children and teens with no regard for known harms to their wellbeing” — while putting increased engagement from young users at the center of their business models. Most of the unsealed documents came from Meta. An internal email shows Mark Zuckerberg decided Meta’s top strategic priority was getting teens “locked in” to Meta’s family of apps. Another damning document discusses allowing “tweens” to use a private mode inspired by fake Instagram accounts (“finstas”). The same document includes an admission that internal data showed Facebook use correlated with lower well-being.

Internal communications showed Meta seemingly bragging that “teens can’t switch off from Instagram even if they want to” and an employee declaring, “oh my gosh yall IG is a drug,” likening all social media platforms to “pushers.”

This 2025 Roku Smart TV Is on Sale for 30% Off

We may earn a commission from links on this page. Deal pricing and availability subject to change after time of publication.

As far as smart TVs go, the Roku interface is one of the easiest to use, and with a variety of different lines, it’s also easy to find one that fits your budget. The Plus Series is the brand’s first attempt at making its own television, and it’s a reliable mid-range smart TV that gives users a plug-and-play experience (no Roku stick or box required), solid picture quality, and fast streaming for the price. Right now, the 55″ 2025 Roku Smart TV Plus Series is 30% off at a record-low $348, down from $499.99.

This model is an upgrade over the Select Series and features a 4K QLED panel with a wide color gamut and a mini-LED backlight. It also supports HDR-10, including Dolby Vision. Colors are vibrant and detailed compared to similarly priced budget TVs, though according to this PCMag review, greens can occasionally look oversaturated. It reaches a peak brightness of approximately 412 nits.

Like all Roku TVs, it has Roku OS built in, giving users access to a wide range of apps and services, and local dimming helps deepen blacks and improve contrast compared to lower-end Roku models. While it isn’t marketed as a gaming TV (it’s only 60Hz and also lacks VRR, which means no AMD FreeSync or Nvidia G-Sync), it still offers a low input lag of 3.1 milliseconds in Game Mode, making it responsive enough for everyday streaming and casual gaming. 

As one of Roku’s first in-house TVs, the 2025 Plus Series has strong value as a budget TV with a panel that’s brighter and delivers deeper blacks than many Amazon Fire TVs in the same price range. While it doesn’t have the faster refresh rate and more advanced features of the pricier Roku Pro Series or premium OLED TVs, it still delivers most of the core Roku TV experience and respectable visuals, making the 55″ 2025 Roku Smart TV Plus Series hit a sweet spot between budget TVs and more expensive models for those who don’t need cutting-edge gaming features.
