Former astronaut on lunar spacesuits: “I don’t think they’re great right now”

Crew members traveling to the lunar surface on NASA’s Artemis missions should be gearing up for a grind. They will wear heavier spacesuits than those worn by the Apollo astronauts, and NASA will ask them to do more than the first Moonwalkers did more than 50 years ago.

The Moonwalking experience will amount to an “extreme physical event” for crews selected for the Artemis program’s first lunar landings, a former NASA astronaut told a panel of researchers, physicians, and engineers convened by the National Academies.

Kate Rubins, who retired from the space agency last year, presented the committee with her views on the health risks for astronauts on lunar missions. She outlined the concerns NASA officials often talk about: radiation exposure, muscle and bone atrophy, reduced cardiovascular and immune function, and other adverse medical effects of spaceflight.

AMDGPU Patches Updated For HDMI Gaming Features On Linux With Radeon Graphics

A patch series posted last week for the open-source AMDGPU kernel driver implements HDMI Variable Rate Refresh “VRR” and other gaming features for HDMI displays. With the HDMI Forum blocking HDMI 2.1 open-source support, these HDMI gaming features for the AMDGPU driver were developed via trial-and-error and the limited public knowledge available. A second iteration of these patches are now available for testing…

New Komoot Apple Watch app enables offline navigation, so you can leave your phone at home

Komoot has announced a new app for Apple Watch users, which works without a smartphone to provide offline maps and navigation, along with turn-by-turn navigation. Users can download maps and routes from Komoot for offline browsing on their watch.

Komoot promises sport-specific maps in its Apple Watch app, with details such as trails and paths, as well as roads. There’s functionality to enable you to pan and zoom to see what’s around you, too.

The Apple Watch app will also track activities and provide real-time stats while on the move and it passes activity data to the Apple Health app.

Komoot updated its user interface last year to make route searches easier.

Other functionality enables the screen to be locked using Apple Water Lock, so it is not susceptible to interference from rain or other moisture. 

According to Komoot product manager, Tom Eldred: “Our goal was to make Komoot’s Apple Watch app fully capable on its own. 

“For many of us, the ability to disconnect is the best part of being outdoors, so we wanted the community to have the freedom to leave their phone at home – or at least in their pocket.”

The new Apple Watch app can be used for an unlocked map region by any user, without needing to be subscribed to Komoot Premium.

First stop on the 2026 development roadmap

Komoot says it plans to improve route planning in its mobile app later in 2026.

Komoot says the Apple Watch app was one of the most frequent requests when it surveyed its user base and conducted more than 100 interviews to understand its users’ needs in 2025.

It updated its user interface last year and claims to have made more than 80 other enhancements since it was bought for around €300m by Italian private equity group Bending Spoons last March. The acquisition reportedly saw the majority of Komoot’s previous 150-strong development team laid off.

Komoot says other new features for the Komoot iOS and Apple Watch apps that are in development include instant syncing between the two, automatic rerouting, real-time location sharing and increased customisation. It’s not the only fitness-tracking app to focus on Apple Watch enhancements, with Strava refreshing its own Apple Watch app at the tail end of 2025.

Komoot’s enhancements are part of its roadmap for app development during 2026, including improved route planning in the mobile app, personal heatmaps and waypoints, easier route searches and better organisation of saved routes. There’s a long-list of further potential enhancements stretching later into 2026.

Is Google Prioritizing YouTube and X Over News Publishers on Discover?

Earlier this month, the media site Press Gazette reported that now Google “is increasingly prioritising AI summaries, X posts and Youtube videos” on its “Discover” feed (which appears on the leftmost homescreen page of many Android phones and the Google app’s homepage).

“The changes could be devastating for publishers who rely heavily on Discover for referral traffic. And it looks set to accelerate a global trend of declining traffic to publishers from both Google search and Discover.”

Xavi Beumala from website analytics platform Marfeel warned in a research update: “Google Discover is no longer a publisher-first surface. It’s becoming an AI platform with YouTube and X absorbing real estate that once went to newsrooms…” [They warn later that “This is not a marginal UI experiment. It is a reallocation of feed real estate away from links and toward inline Youtube plays and generated summaries.”] Google says it prioritises “helpful, reliable, people-first content”. Unlike Google News, there is no requirement that Google Discover showcases bona fide publisher websites.

In recent months fake news stories published by fraudulent website publishers have been promoted on Google Discover, reaping tens of millions of clicks. Google said it was working on a “fix” for this issue…

Facebook, Instagram and Tiktok content may also start flowing into the Discover feed in future. When Google announced the addition of posts from X, Instagram and Youtube Shorts in September, it said there would be “more platforms to come”.

Startup Uses SpaceX Tech to Cool Data Centers With Less Power and No Water

California-based Karman Industries “says it has developed a cooling system that uses SpaceX rocket engine technology to rein in the environmental impact of data centers,” reports the Los Angeles Times, “chilling them with less space, less power and no water.”

Karman has developed a cooling system similar to the heat pumps in the average home, except its pumps use liquid carbon dioxide as refrigerant, which is circulated using rocket engine technology rather than fans. The company’s efficient pumps can reduce the space required for data center cooling equipment by 80%.

Over the years, data centers have used fans and air conditioning to blow cold air on the chips. Bigger facilities pass cold liquid through tubes near the chips to absorb the heat. This hot liquid is sent outside to a cooling yard, where sprawling networks of pipes use as much water as a city of 50,000 people to remove the heat. A 50 megawatt data center also uses enough electricity to power a mid-sized city… Cooling systems account for up to 40% of a data center’s power consumption and an average midsized data center consumes more than 35,000 gallons of water per day…

U.S. data centers will consume about 8% of all electricity in the country by 2030, according to the International Energy Agency… The cooling systems are projected to use up to 33 billion gallons of water by 2028 per year… To serve this seemingly insatiable market, Karman has developed a rotating compressor that spins at 30,000 revolutions per minute — nearly 10 times faster than traditional compressors — to move heat…

About a third of Karman’s 23-person team came from SpaceX or Rocket Lab, and they co-opted technologies from aerospace engineering and electric vehicles to design the mechanics for the high-speed motors. The system uses a special type of carbon dioxide under high pressure to transfer heat from the data center to the outside air. Depending on the conditions, it can do the same amount of cooling using less than half the energy. Karman’s heat pump can either reject heat to air, or route it into extra cooling, or even power generation.
The company “recently raised $20 million,” according to the article, “and expects to start building its first compressors in Long Beach later this year….”

New Linux/Android 2-in-1 Tablet ‘Open Slate’ Announced by Brax Technologies

Brax Technologies just announced “a privacy-focused alternative to locked-down tablets” called open_slate that can double as a consumer tablet and a Linux-capable workstation on ARM.

Earlier Brax Technologies built the privacy-focused smartphone BraX3, which co-founder Plamen Todorov says proved “a privacy-focused mobile device could be designed, crowdfunded, manufactured, and delivered outside the traditional Big Tech ecosystem.”

Just as importantly, BraX3 showed us the value of building with the community. The feedback we received — what worked, what didn’t, and what people wanted next — played a major role in shaping our direction going forward. Today, we’re ready to share the next step in that journey…

They’re promising their “2-in-1″ open_slate tablet will be built with these guiding principles:

Modularity beyond repairability”. (“In addition to a user-replaceable battery, it supports an M.2 expansion slot, allowing users to customize storage and configurations to better fit their needs.”)
Hardware-level privacy and control, with physical switches allowing users to disable key components like wireless radios, sensors, microphones, and cameras.
Multi-OS compatibility, supporting “multiple” Android-based operating systems as well as native Linux distributions. (“We’re working with partners and the community to ensure proper, long-term OS support rather than one-off ports.”)
Longevity by design — a tablet that’s “supported over time”
Brax has already created an open thread with preliminary design specs. “The planned retail price is 599$ for the base version and 799$ for the Pro version,” they write. “We will be offering open_slate (both versions) at a discount during our pre-order campaign, starting as low as 399$ for the base version and 529$ for the Pro version for limited quantities only which may sell out in a day or two from launching pre-orders…

“Pre-orders will open in February, via IndieGoGo. Make sure to subscribe for notifications if you don’t want to miss the launch date.”

KDE’s ‘Plasma Login Manager’ Stops Supporting FreeBSD – Because Systemd

KDE’s “Plasma Login Manager” is apparently dropping support for FreeBSD, the Unix-like operating system, reports the blog It’s FOSS. They cite a recently-accepted merge request from a KDE engineer to drop the code supporting FreeBSD, since the login manager relies on systemd/logind:

systemd and logind look like hard dependencies of the login manager, which means the software is built to work exclusively with these components and cannot function without them… logind is a component of systemd that is responsible for user session management…
This doesn’t mean that KDE has abandoned the operating system altogether. FreeBSD users can still run the KDE Plasma desktop environment and continue using SDDM, the current login manager that works just fine on such systems.

The article argues FreeBSD users “won’t really care much for missing out on this as they have plenty of login manager options available.”

Washington State May Mandate ‘Firearm Blueprint Detection Algorithms’ For 3D Printers

Adafruit managing director Phillip Torrone (also long-time Slashdot reader ptorrone ) writes: Washington State lawmakers are proposing bills (HB 2320 and HB 2321) that would require 3D printers and CNC machines to block certain designs using software-based “firearms blueprint detection algorithms.” In practice, this means scanning every print file, comparing it against a government-maintained database, and preventing “skilled users” from bypassing the system. Supporters frame this as a response to untraceable “ghost guns,” but even federal prosecutors admit the tools involved are ordinary manufacturing equipment. Critics warn the language is overbroad, technically unworkable, hostile to open source, and likely to push printing toward cloud-locked, subscription-based systems—while doing little to stop criminals.

Google Discover Replaces News Headlines With Sometimes Inaccurate AI-Generated Alternatives

An anonymous reader shared this report from The Verge:

In early December, I brought you the news that Google has begun replacing Verge headlines, and those of our competitors, with AI clickbait nonsense in its content feed [which appears on the leftmost homescreen page of many Android phones and the Google app’s homepage]. Google appeared to be backing away from the experiment, but now tells The Verge that its AI headlines in Google Discover are a feature, one that “performs well for user satisfaction.” I once again see lots of misleading claims every time I check my phone…

For example, Google’s AI claimed last week that “US reverses foreign drone ban,” citing and linking to this PCMag story for the news. That’s not just false — PCMag took pains to explain that it’s false in the story that Google links to…! What does the author of that PCMag story think? “It makes me feel icky,” Jim Fisher tells me over the phone. “I’d encourage people to click on stories and read them, and not trust what Google is spoon-feeding them.” He says Google should be using the headline that humans wrote, and if Google needs a summary, it can use the ones that publications already submit to help search engines parse our work.

Google claims it’s not rewriting headlines. It characterizes these new offerings as “trending topics,” even though each “trending topic” presents itself as one of our stories, links to our stories, and uses our images, all without competent fact-checking to ensure the AI is getting them right… The AI is also no longer restricted to roughly four words per headline, so I no longer see nonsense headlines like “Microsoft developers using AI” or “AI tag debate heats.” (Instead, I occasionally see tripe like “Fares: Need AAA & AA Games” or “Dispatch sold millions; few avoided romance.”)

But Google’s AI has no clue what parts of these stories are new, relevant, significant, or true, and it can easily confuse one story for another. On December 26th, Google told me that “Steam Machine price & HDMI details emerge.” They hadn’t. On January 11th, Google proclaimed that “ASUS ROG Ally X arrives.” (It arrived in 2024; the new Xbox Ally arrived months ago.) On January 20th, it wrote that “Glasses-free 3D tech wows,” introducing readers to “New 3D tech called Immensity from Leia” — but linking to this TechRadar story about an entirely different company called Visual Semiconductor…

Google declined our request for an interview to more fully explain the idea.

The site Android Police spotted more inaccurate headlines in December:

A story from 9to5Google, which was actually titled ‘Don’t buy a Qi2 25W wireless charger hoping for faster speeds — just get the ‘slower’ one instead’ was retitled as ‘Qi2 slows older Pixels.’ Similarly, Ars Technica’s ‘Valve’s Steam Machine looks like a console, but don’t expect it to be priced like one’ was changed to ‘Steam Machine price revealed.’ At the time, we believed that the inaccuracies were due to the feature being unstable and in early testing…. Now, Google has stopped calling Discover replacing human-written headlines as an “experiment.”

“Google buries a ‘Generated with AI, which can make mistakes’ message under the ‘See more’ button in the summary,” reports 9to5Google, “making it look like this is the publisher’s intended headline.”
While it is obvious that Google has refined this feature over the past couple of months, it doesn’t take long to still find plenty of misleading headlines throughout Discover… Another article from NotebookCheck about an Anker power bank with a retractable cable was given a headline that’s about another product entirely. A pair of headlines from Tom’s Hardware and PCMag, meanwhile, show the two sides of using AI for this purpose. The Tom’s Hardware headline, “Free GPU & Amazon Scams,” isn’t representative of the actual article, which is about someone who bought a GPU from Amazon, canceled their order, and the retailer shipped it anyway. There’s nothing about “Amazon Scams” in the article.
