alternative_right shares a report from Phys.org: Scientists from Taiwan have developed a new material that can stretch up to 4,600% of its original length before breaking. Even if it does break, gently pressing the pieces together at room temperature allows it to heal, fully restoring its shape and stretchability within 10 minutes.

The sticky and stretchy polyurethane (PU) organogels were designed by combining covalently linked cellulose nanocrystals (CNCs) and modified mechanically interlocked molecules (MIMs) that act as artificial molecular muscles. The muscles make the gel sensitive to external forces such as stretching or heat, where its color changes from orange to blue based on whether the material is at rest or stimulated. Thanks to these unique properties, the gels hold great promise for next-generation technologies — from flexible electronic skins and soft robots to anti-counterfeiting solutions. The findings have been published in the journal Advanced Functional Materials.

An anonymous reader quotes a report from Reuters: On the outskirts of this city of 21 million, a showroom in a shopping mall offers extraordinary deals on new cars. Visitors can choose from some 5,000 vehicles. Locally made Audis are 50% off. A seven-seater SUV from China’s FAW is about $22,300, more than 60% below its sticker price. These deals — offered by a company called Zcar, which says it buys in bulk from automakers and dealerships — are only possible because China has too many cars. Years of subsidies and other government policies have aimed to make China a global automotive power and the world’s electric-vehicle leader. Domestic automakers have achieved those goals and more — and that’s the problem.

China has more domestic brands making more cars than the world’s biggest car market can absorb because the industry is striving to hit production targets influenced by government policy, instead of consumer demand, a Reuters examination has found. That makes turning a profit nearly impossible for almost all automakers here, industry executives say. Chinese electric vehicles start at less than $10,000; in the U.S., automakers offer just a few under $35,000. Most Chinese dealers can’t make money, either, according to an industry survey published last month, because their lots are jammed with excess inventory. Dealers have responded by slashing prices. Some retailers register and insure unsold cars in bulk, a maneuver that allows automakers to record them as sold while helping dealers to qualify for factory rebates and bonuses from manufacturers.

Unwanted vehicles get dumped onto gray-market traders like Zcar. Some surface on TikTok-style social-media sites in fire sales. Others are rebranded as “used” — even though their odometers show no mileage — and shipped overseas. Some wind up abandoned in weedy car graveyards. These unusual practices are symptoms of a vastly oversupplied market — and point to a potential shakeout mirroring turmoil in China’s property market and solar industry, according to many industry figures and analysts. They stem from government policies that prioritize boosting sales and market share — in service of larger goals for employment and economic growth — over profitability and sustainable competition. Local governments offer cheap land and subsidies to automakers in exchange for production and tax-revenue commitments, multiplying overcapacity across the country.

Research shows China’s top AI firm DeepSeek gives weaker or insecure code when programmers identify as linked to Falun Gong or other groups disfavored by Beijing. It offers higher-quality results to everyone else. “The findings … underscore how politics shapes artificial intelligence efforts during a geopolitical race for technology prowess and influence,” reports the Washington Post. From the report: In the experiment, the U.S. security firm CrowdStrike bombarded DeepSeek with nearly identical English-language prompt requests for help writing programs, a core use of DeepSeek and other AI engines. The requests said the code would be employed in a variety of regions for a variety of purposes.

Asking DeepSeek for a program that runs industrial control systems was the riskiest type of request, with 22.8 percent of the answers containing flaws. But if the same request specified that the Islamic State militant group would be running the systems, 42.1 percent of the responses were unsafe. Requests for such software destined for Tibet, Taiwan or Falun Gong also were somewhat more apt to result in low-quality code. DeepSeek did not flat-out refuse to work for any region or cause except for the Islamic State and Falun Gong, which it rejected 61 percent and 45 percent of the time, respectively. Western models won’t help Islamic State projects but have no problem with Falun Gong, CrowdStrike said.

Those rejections aren’t especially surprising, since Falun Gong is banned in China. Asking DeepSeek for written information about sensitive topics also generates responses that echo the Chinese government much of the time, even if it supports falsehoods, according to previous research by NewsGuard. But evidence that DeepSeek, which has a very popular open-source version, might be pushing less-safe code for political reasons is new. CrowdStrike Senior Vice President Adam Meyers and other experts suggest three possible explanations for why DeepSeek produced insecure code.

One is that the AI may be deliberately withholding or sabotaging assistance under Chinese government directives. Another explanation is that the model’s training data could be uneven: coding projects from regions like Tibet or Xinjiang may be of lower quality, come from less experienced developers, or even be intentionally tampered with, while U.S.-focused repositories may be cleaner and more reliable (possibly to help DeepSeek build market share abroad).

A third possibility is that the model itself, when told that a region is rebellious, could infer that it should produce flawed or harmful code without needing explicit instructions.

This is an animated Back To The Future short made by Landon’s Animation Wheelhouse featuring Doc and Marty wreaking havoc in their time-traveling Delorean (including causing the extinction of the dinosaurs and sinking the Titanic). Unhinged is definitely accurate. Would I watch a full length version? Are you kidding? I’ve already been trying to get AI to make a 12 hour version. “He’s been screaming at Alexa for 30 minutes straight.” Oh is it Alexa? I was calling her Siri. Maybe that’s why she isn’t delivering.

After revealing his company’s latest augmented reality and smart glasses at Meta Connect this year, Mark Zuckerberg has introduced a new entertainment hub for its Quest headsets called Horizon TV. Zuckerberg said Meta believes watching video content is going to be a huge category for both virtual reality headsets and glasses in the future. Meta has already teamed up with several major streaming services to provide shows and movies you can enjoy in VR. One of those partners is Disney+, which will give users access to the Marvel Cinematic Universe on their headsets, as well as to content from ESPN and Hulu. 

Based on the interface Zuckerberg showed on the event, which had a lineup of streaming apps that will be available on the hub, Meta also teamed up with Prime Video, Spotify, Peacock and Twitch. That will allow you to watch shows, such as The Boys and Fallout on your virtual reality devices. Meta also partnered with Universal Pictures and iconic horror company Blumhouse, so that you can watch horror flicks like M3GAN and The Black Phone on your Quest “with immersive special effects you won’t find anywhere else.”

The Horizon TV hub supports Dolby Atmos for immersive sounds, with Dolby Vision arriving later this year for richer colors and crisper details. For a limited time, you’ll be able to watch an exclusive 3D clip of Avatar: Fire and Ash on Horizon TV, as well, as part of Meta’s partnership with James Cameron’s Lightstorm Vision.

Wild chimpanzees have been found to consume the equivalent of a bottle of lager’s alcohol a day from eating ripened fruit, scientists say. BBC: They say this is evidence humans may have got our taste for alcohol from common primate ancestors who relied on fermented fruit — a source of sugar and alcohol — for food. “Human attraction to alcohol probably arose from this dietary heritage of our common ancestor with chimpanzees,” said study researcher Aleksey Maro of the University of California, Berkeley.

Chimps, like many other animals, have been spotted feeding on ripe fruit lying on the forest floor, but this is the first study to make clear how much alcohol they might be consuming.

The research team measured the amount of ethanol, or pure alcohol, in fruits such as figs and plums eaten in large quantities by wild chimps in Cote d’Ivoire and Uganda. Based on the amount of fruit they normally eat, the chimps were ingesting around 14 grams of ethanol — equivalent to nearly two UK units, or roughly one 330ml bottle of lager. The fruits most commonly eaten were those highest in alcohol content.

Yesterday, the US National Highway Traffic Safety Administration opened an investigation into Tesla following a report by Bloomberg that its electric door handles could stop working when a vehicle’s low-voltage battery fails. That created a safety hazard that the publication found could trap passengers when a Tesla car was in an emergency situation, such as a crash. Now, Bloomberg is back with the news that Tesla plans to redesign those problematic handles. 

Tesla design head Franz von Holzhausen appeared on Bloomberg‘s Hot Pursuit! podcast and said the company is considering a new approach that combines the electric and manual release mechanisms. “The idea of combining the electronic one and the manual one together into one button, I think, makes a lot of sense,” he said. “That’s something that we’re working on.” He didn’t specify why Tesla was working on a redesign, but it’s hard to imagine the timing of the federal probe isn’t relevant. 

The company has already been in the NHTSA’s sights this year. Last month, the regulator opened an investigation into how Tesla was reporting crashes with its Autopilot and Full Self-Driving systems. Although Tesla claimed the inconsistencies in reports were due to a system error that it has fixed, the NHTSA said it would continue the probe.

Dalia is a death cleaner.

Death cleaning, as we know it, is the process of sanitizing and tidying the spaces where people take their final breaths, sometimes long after their bodies have begun to decompose. It’s a job here on Earth in the year 2025, but Dalia’s version of death cleaning takes place on the rings of Saturn in a distant future filled with space travel, interplanetary colonization and devastating disease outbreaks. In this scenario, death cleaning involves spraying chemicals over bulging piles of otherworldly contamination and avoiding their defense mechanisms, which can cause fires, explosions and electrical interference. Dalia learns from the alien material as she cleans, harvesting fruit from fungal mounds to create new options for her sprayer. She also listens to the last words of the dead.

Ambrosia Sky is the first game from independent studio Soft Rains and its story trailer landed on Wednesday. In Ambrosia Sky, Dalia is cleaning the Cluster, an agricultural outpost on Saturn’s rings that collapsed when a mysterious biological force subsumed the colony and its people. It’s also Dalia’s former home.

As a Scarab with The Ambrosia Project, her job is to clear out the alien fungus, research its origins and perform Death Rites on the corpses she encounters. Scarabs operate in the shadowy spaces between science and mysticism, and The Ambrosia Project’s goal is to discover a cure for mortality among the stars. Death Rites involve hearing the deceased person’s Last Will and cremating their body with specialized spores, adding their DNA to The Ambrosia Project for further research. It’s a ritualistic acknowledgement of a person’s life as much as their death, and these small ceremonies are just as critical in Ambrosia Sky as the game’s first-person cleaning mechanics.

“I really let myself and our team explore more mythological or fantastical elements, or even folkloric elements, because I think there’s only so much we can know about outer space,” Soft Rains narrative director Kaitlin Tremblay told Engadget. “[Also] there are things that we know concretely about death, but there’s so much about it we don’t know. I think it’s the same kind of interesting liminal space. What don’t we know, and how do we tell stories and try to comfort ourselves and contend with that? That actually makes my brand of sci-fi and my approach on death really similar.”

Ambrosia Sky is an investigation of the universe and mortality alike, in the form of a first-person, speculative-fiction cleaning sim on Saturn’s rings. It features zero-gravity scenes, crafting, equipment upgrades and classic FPS play, underpinned by a slowly unfurling story of lethal disaster. 

Soft Rains has been quietly working on Ambrosia Sky since late 2022 and formally announced the game in March 2025. The studio was founded by Tremblay — who was narrative designer on Watch Dogs Legion and Grindstone, and lead writer of A Mortician’s Tale and Seasonala Cemetery — and other industry veterans from Bethesda, Ubisoft and indie teams.

Ambrosia Sky’s story trailer features a staticky, disembodied voice saying, “Hey, Dalia. It’s me. When I die, I want a Scarab called in. And I want it to be you.” It’s surprisingly heart-wrenching, for a two-minute teaser of a sci-fi clean-em-up.

Soft Rains

“It’s just honest, right?” Tremblay said. “We have a lot of emotions about death, and our own death and everything around it. Some of those emotions contain brightness and some of them contain darkness, and both are equally valid. Both can exist at the same time.”

Death is a regular visitor in Tremblay’s writing. In particular, A Mortician’s Tale is an acclaimed presentation of the business of mortality, and Seasonala Cemetery is a meditative experience about spending time in a graveyard. In a devlog entry on June 10, Tremblay compared the mortality angle in Ambrosia Sky to that of A Mortician’s Tale, writing, “With Ambrosia Sky, we wanted to have the opportunity to explore how we feel about our own death, rather than the death of our loved ones.”

I was struck by this distinction when I first read it, and because I’m also consumed by thoughts of my own inescapable expiration, I asked Tremblay for more. They said the following:

“That is particularly the approach I’m taking for the Death Rituals. The Death Rituals are when you find those individuals in the world and you sample their DNA for the project, but you’re also listening to their recorded Last Wills. I really wanted those to be a moment to let the characters talk authentically about what their death actually means to them. Because I feel like in my work and in so many other games, it’s often about how we feel about death, or our grief or our mourning process.

“I think this is probably a symptom of post-pandemic brain and getting older, but I’m thinking a lot more about what does my death actually mean to me, and trying to sit with it in a way that doesn’t keep me up until 4AM. So I think this is really that kind of approach. We all probably think about our own death and people have a lot of feelings on their own potential death, and so I wanted to give voice to that, and have this space to talk through and work through some of those emotions.”

And clean up giant tendrils of neon fungus, of course.

Ambrosia Sky is being developed and published by Soft Rains, and it’s due to come out “soon.” A demo is available now on Steam.

Sony has quietly introduced a revised PlayStation 5 Digital Edition that reduces internal storage from 1TB to 825GB while maintaining the same 499 Euro ($590) price point. The CFI-2116 revision has appeared on Amazon listings across Italy, Germany, Spain and France without official announcement from Sony.

The storage downgrade returns the console to its original 825GB capacity last seen in the launch PlayStation 5 before the Slim models increased storage to 1TB. Users lose approximately 175 of usable space in the new revision. Amazon Germany lists October 23 as the delivery date for units already available for purchase. The change affects only the Digital Edition while the disc version remains unchanged at 1TB. The revision follows Sony’s September price increase of $50 across PlayStation 5 models citing economic conditions.

Evolution has adapted the digits of mammals for an enormous range of uses, from our opposable thumbs to the spindly digits that support bat wings to the robust bones that support the hoofs of horses. But how we got digits in the first place hasn’t been entirely clear. The fish that limbed vertebrates evolved from don’t have obvious digit equivalents, and the most common types of fish just have a large collection of rays supporting their fins.

Despite this uncertainty, we have identified some genes that seem to be essential for both digit formation and the development of rays in the fins of fish, suggesting that there are parallels between the two. But a new study suggests that these parallels are a bit of an accident, and digits come by re-deploying a genetic network that controls a completely different process: the formation of the cloaca, a single organ that handles all of the fish’s excretion.

Hox genes and digits

One of the key regulators of limb development is a set of genes called homeobox proteins, which attach to DNA and regulate the activity of nearby genes. In animals, many of these homeobox, or hox genes, are formed into clusters. Mammals have four clusters of hox genes, each of which encodes roughly 10 individual homeobox proteins. The cluster helps to organize where the hox genes are active, with the genes at one end of the cluster being active at the front of an embryo, and those at the other end active at the tail.
