Scripps Research scientists sent stem-cell-derived brain organoids to the ISS to study the effects of microgravity on brain cells, finding that the organoids matured faster and showed signs of specialization compared to Earth-grown controls. The findings have been published in the journal Stem Cells Translational Medicine. Phys.Org reports: To examine how the space environment impacts cellular functions, the team compared the cells' RNA expression patterns -- a measure of gene activity -- to identical "ground control" organoids that had remained on Earth. Surprisingly, they found that the organoids grown in microgravity had higher levels of genes associated with maturity and lower levels of genes associated with proliferation compared to the ground controls, meaning that the cells exposed to microgravity developed faster and replicated less than those on Earth. "We discovered that in both types of organoids, the gene expression profile was characteristic of an older stage of development than the ones that were on the ground," [says co-senior author Jeanne Loring, Ph.D., professor emeritus in the Department of Molecular Medicine and founding director of the Center for Regenerative Medicine at Scripps Research]. "In microgravity, they developed faster, but it's really important to know these were not adult neurons, so this doesn't tell us anything about aging."

The team also noted that contrary to their hypothesis, there was less inflammation and lower expression of stress-related genes in organoids grown in microgravity, but more research is needed to determine why. Loring speculates that microgravity conditions may more closely mirror the conditions experienced by cells within the brain compared to organoids grown under conventional lab conditions and in the presence of gravity. "The characteristics of microgravity are probably also at work in people's brains, because there's no convection in microgravity -- in other words, things don't move," says Loring. "I think that in space, these organoids are more like the brain because they're not getting flushed with a whole bunch of culture medium or oxygen. They're very independent; they form something like a brainlet, a microcosm of the brain." "The next thing we plan to do is to study the part of the brain that's most affected by Alzheimer's disease," says Loring. "We also want to know whether there are differences in the way neurons connect with each other in space. With these kinds of studies, you can't rely on earlier work to predict what the result would be because there is no earlier work. We're on the ground floor, so to speak; in the sky, but on the ground floor."

One in five adults in developed nations demonstrate primary school-level literacy and numeracy skills, according to an OECD study of 160,000 people across 31 countries released December 10. The decennial Survey of Adult Skills reveals declining literacy rates over the past decade despite rising secondary education completion.

Finland topped rankings across all tested areas -- numeracy, literacy, and problem-solving -- while Japan, Norway and the Netherlands performed above average. The United States showed declining scores, with Chile, Italy, Poland and Portugal reporting high proportions of below-average performers. The study found widening skill gaps between top and bottom performers, with declining scores concentrated among lower-performing adults.

An anonymous reader quotes a report from Ars Technica: A sophisticated and ongoing supply-chain attack operating for the past year has been stealing sensitive login credentials from both malicious and benevolent security personnel by infecting them with Trojanized versions of open source software from GitHub and NPM, researchers said. The campaign, first reported three weeks ago by security firm Checkmarx and again on Friday by Datadog Security Labs, uses multiple avenues to infect the devices of researchers in security and other technical fields. One is through packages that have been available on open source repositories for over a year. They install a professionally developed backdoor that takes pains to conceal its presence. The unknown threat actors behind the campaign have also employed spear phishing that targets thousands of researchers who publish papers on the arXiv platform.

The objectives of the threat actors are also multifaceted. One is the collection of SSH private keys, Amazon Web Services access keys, command histories, and other sensitive information from infected devices every 12 hours. When this post went live, dozens of machines remained infected, and an online account on Dropbox contained some 390,000 credentials for WordPress websites taken by the attackers, most likely by stealing them from fellow malicious threat actors. The malware used in the campaign also installs cryptomining software that was present on at least 68 machines as of last month. It's unclear who the threat actors are or what their motives may be. Datadog researchers have designated the group MUT-1244, with MUT short for "mysterious unattributed threat."

Google today unveiled Project Mariner, its first AI agent capable of autonomously navigating web browsers, operating through a Chrome extension that controls cursor movements and form-filling to replicate human interactions online.

The Gemini-powered prototype, developed by Google's DeepMind division, is initially available to a select group of testers. During demos, the agent performed tasks like creating shopping carts on grocery websites, though with noticeable five-second delays between actions. The system captures browser screenshots and processes them through Gemini in the cloud to generate navigation commands.

It operates only in Chrome's active tab, requiring users to observe its actions rather than running in the background. Project Mariner achieved an 83.5% success rate on the WebVoyager benchmark for web-based tasks. The agent has built-in limitations, including inability to complete purchases, accept cookies, or agree to terms of service. Google Labs Director Jaclyn Konzelmann described the project as a "fundamentally new UX paradigm shift" that could transform how users interact with websites. The company said it is engaging with web ecosystem stakeholders as development continues.

"Mercedes-Benz is researching a new type of solar modules that could be seamlessly applied to the bodywork of electric vehicles," according to a recent Mercedes-Benz press release.

They describe the 5-micrometer coating as "similar to a wafer-thin layer of paste... significantly thinner than a human hair" — but creating an active photovoltaic surface with an efficiency of 20%. An area of 118.4 square feet (equivalent to the surface of a mid-size SUV) could produce energy for up to 7,456 miles per year under ideal conditions [based on daylight conditions from their testing in Stuttgart]. The energy generated by the solar cells is used for driving or fed directly into the high-voltage battery...

Solar paint has a high level of efficiency and contains no rare earths or silicon — only non-toxic, readily available raw materials. It is easy to recycle and considerably cheaper to produce than conventional solar modules. The Mercedes-Benz research department is currently working to enable use of the new solar paint on all exterior vehicle surfaces — regardless of shape or angle.
Solar paint could power 62% of the travel for a typical Stuttgart driver, their announcement notes. But in a sunnier city like Los Angeles, "It could be used for 100% of their driving, on average." (And "the surplus of energy could be fed directly into the home network via bidirectional charging.")

Mercedes-Benz researchers "initially thought the tech had limited scope for mass production," reports EV Central, "until experiments were carried out with prototypes coated with the paint in real-world scenarios. Instead of just coating the roof and bonnet to form a 1.8-square-metre surface area, one scientist suggested covering an entire car with the new solar paint, ramping up the surface area to more than 11m2. Another difference to the [Mercedes-Benz 2022 Vision EQXX concept] is instead of wiring the body panels to the 12-volt system, scientists hardwired the body panels to the Benz's high-voltage battery and the performance of the paint was well beyond expectations... Available in all colours, engineers admit the solar paint work best in darker shades. When it's launched, the tech should be as durable as regular paint. The photovoltaic surface is protected by at least two protective lacquer finishes to ensure it isn't damaged in daily use.
Mercedes-Benz says the solar paint could mean "increased electric range and fewer charging stops." And this is significant, because "Electric vehicle charging and infrastructure are two major obstacles to EV adoption on a mass scale," writes Autoblog — arguing that Mercedes-Benz "may have a solution... " Alternative methods of energy harnessing could help alleviate range anxiety, increase an EV's driving distance, and reduce charging costs across the board. Not only that but considering the cost of producing Mercedes' solar coating and the lack of rare earth metals, it could be the leading solution to charging concerns... While the German automaker says the solar paint isn't ready for production on a mass scale, research, and development are progressing at a steady rate. If all goes well, we'll hopefully see solar coating as an accessory EV charging solution within the next decade.

Peter Jackson is co-executive producer of a new animated Lord of the Rings prequel called The War of the Rohirrim. "Set in an epic world 183 years before the events of The Lord of the Rings trilogy, the King of Rohan is forced into a last stand in ancient Hornburg after a sudden attack..." explains The Hollywood Reporter.

But Variety writes that the movie "fizzled" in its overseas debut this weekend: "Moana 2" has notched $600 million in global ticket sales, standing as the sixth-biggest movie of the year after just two weeks of release. Disney's animated sequel, which was developed as a TV series before pivoting to theaters, has generated $300 million overseas and $300 million domestically... Among new offerings, the Warner Bros. anime fantasy film "The Lord of the Rings: The War of the Rohirrim," faltered with $2 million from 3,410 screens in 31 territories... [The movie] opens in North America and an additional 42 offshore markets on Dec. 13. Top earning territories were Spain with $347,000 followed by Mexico with $239,000 and Thailand with $146,000...

Meanwhile, Paramount's "Gladiator II" collected $17 million in its fourth frame at the international box office, boosting its tally to $235 million overseas and $368.4 million globally. The quarter-century-in-the-making sequel Ridley Scott's Oscar-winning 2000 epic "Gladiator" has been far bigger in offshore markets... There's also "Red One," a Christmas-set action comedy starring the Rock as Santa's head of security, which collected $3.5 million from 4,000 screens in 75 overseas markets. The film, from Amazon MGM, has generated a soft $78.2 million from offshore territories and $164 million globally. "Red One" was originally destined for streaming before the studio opted for a theatrical release, so any coinage from the big screen could be viewed as a win for movie theaters, Amazon MGM and Warner Bros. (which has international rights on Amazon MGM releases). From a strictly theatrical standpoint, though, "Red One" carries a $250 million budget before marketing and stands as one of the year's biggest misfires.

The Washington Post details a vision of home security "pitched by Sauron, a Silicon Valley start-up boasting a waiting list of tech CEOs and venture capitalists." In the future, your home will feel as safe from intruders as a state-of-the-art military base. Cameras and sensors surveil the perimeter, scanning bystanders' faces for potential threats. Drones from a "deterrence pod" scare off trespassers by projecting a searchlight over any suspicious movements. A virtual view of the home is rendered in 3D and updated in real time, just like a Tesla's digital display. And private security agents monitor alerts from a central hub.... By incorporating technology developed for autonomous vehicles, robotics and border security, Sauron has built a supercharged burglar alarm [argued Sauron co-founder Kevin Hartz, a tech entrepreneur and former partner at Peter Thiel's venture firm Founders Fund]...

For many tech elites, security is both a national priority and a growing concern in their personal lives... After the presidential election last month, the start-up incubator Y Combinator put out a request for "public safety technology" companies, such as those that produce tools that facilitate a neighborhood watch or technology that uses computer vision to identify "suspicious activities or people in distress from video feeds...." Sauron has raised $18 million in funding from executives behind Flock Safety and Palantir, the data analytics firm, [and] defense tech investors such as 8VC, a venture firm started by Palantir co-founder Joe Lonsdale... Sauron is targeting homeowners at the high end of the real estate market, beginning with a private event at Abraham's home on Thursday, during Art Basel Miami Beach, the annual art exhibition that attracts collectors from around the world. The company plans to launch in San Francisco early next year, before expanding to Los Angeles and Miami...

Big Tech companies haven't deployed tools such as facial recognition as aggressively as Hartz would like. "If somebody comes onto my property, I feel like I should know who that is," Hartz said... In recent years massive investments have driven down the cost of drones, high-resolution cameras and lidar sensors, which use light detection to create 3D maps. Sauron uses lower-cost hardware and tools like facial recognition, combined with custom-built software adapted for residential use. For facial recognition, it will use a third-party service called Paravision... Sauron is still figuring out how to incorporate drones, but it is already imagining more aggressive countermeasures, Hartz said. "Is it a machine that could take out a bad actor with a bullet or something?"

"The Rust Foundation is dedicated to ensuring a healthy Rust ecosystem," according to a new announcement today, " which depends on a growing pool of well-trained developers to thrive." The latest SlashData Developer Nation survey found Rust to be the fastest-growing programming language, doubling its users over the past two years. As Rust's adoption continues to accelerate, the demand for a multifaceted ecosystem of quality training will too.
Their blog post highlights three examples of the Rust community "creating new pathways for learning Rust" and "addressing the critical need for Rust training in academic settings..." Rust-Edu operates as a non-profit through Portland State University, with funding from Futurewei. Their mission is to "spread Rust use and development through academic curricula and communities throughout the world, making Rust the language of choice for 'systems programming' in its broadest sense through shared efforts of faculty, students and the Rust community." They focus on three main areas: curriculum development, educational tools, and language improvements...

teach-rs, pronounced "teachers," is a modular and reusable university course designed for in-person teaching in Rust. Its mission is to introduce Rust in higher education and ensure that more students enter the job market with considerable Rust experience. The teach-rs project provides ready-to-use Rust teaching materials, including slide decks and exercises that can be adapted to various teaching contexts... As an open source permissively licensed project, teach-rs enables educators to share and improve resources, making introducing Rust instruction into their programs more accessible. Many institutions now use teach-rs in their courses, including the Slovak University of Technology, RustIEC (a collaboration between Vrije Universiteit Brussel and KU Leuven), and the University Politehnica of Bucharest. At the time of this writing, teach-rs has nearly 3000 stars on GitHub...

Under the guidance of The Rust Foundation's Global Rust Coordinator and Rust Nation UK's organizer Ernest Kissiedu, Mordecai Etukudo (Mart) has developed a guide to help educational institutions adopt Rust in their systems. This resource walks organizations through the entire implementation process, from initial assessment to community engagement.

A handful of countries should be held legally responsible for the ongoing impacts of climate change, representatives of vulnerable states have told judges at the international court of justice (ICJ). From a report: During a hearing at the Peace Palace in The Hague, which began on Monday, Ralph Regenvanu, Vanuatu's special envoy for climate change and environment, said responsibility for the climate crisis lay squarely with "a handful of readily identifiable states" that had produced the vast majority of greenhouse gas emissions but stood to lose the least from the impacts.

The court heard how Pacific island states such as Vanuatu were bearing the brunt of rising sea levels and increasingly frequent and severe disasters. "We find ourselves on the frontlines of a crisis we did not create," Regenvanu said. The hearing is the culmination of years of campaigning by a group of Pacific island law students and diplomacy spearheaded by Vanuatu. In March last year the UN general assembly unanimously approved a resolution calling on the ICJ to provide an advisory opinion on what obligations states have to tackle climate change and what the legal consequences could be if they fail to do so.

Over the next two weeks, the court will hear statements from 98 countries, including wealthy developed states with the greatest historical responsibility for the climate emergency, such as the UK and Russia, and states that have contributed very little to global greenhouse gas emissions but stand to bear the brunt of their impact, including Bangladesh and Sudan as well as Pacific island countries.

An anonymous reader quotes a report from IEEE Spectrum: Virtual- and augmented-reality setups already modify the way users see and hear the world around them. Add in haptic feedback for a sense of touch and a VR version of Smell-O-Vision, and only one major sense remains: taste. To fill the gap, researchers at the City University of Hong Kong have developed a new interface to simulate taste in virtual and other extended reality (XR). The group previously worked on other systems for wearable interfaces, such as haptic and olfactory feedback. To create a more "immersive VR experience," they turned to adding taste sensations, says Yiming Liu, a coauthor of the group's research paper published today in the Proceedings of the National Academy of Sciences.

The lollipop-shaped lickable device can produce nine different flavors: sugar, salt, citric acid, cherry, passion fruit, green tea, milk, durian, and grapefruit. Each flavor is produced by food-grade chemicals embedded in a pocket of agarose gel. When a voltage is applied to the gel, the chemicals are transported to the surface in a liquid that then mixes with saliva on the tongue like a real lollipop. Increase the voltage, and get a stronger flavor. Initially, the researchers tested several methods for simulating taste, including electrostimulating the tongue. The other methods each came with limitations, such as being too bulky or less safe, so the researchers opted for chemical delivery through a process called iontophoresis, which moves chemicals and ions through hydrogels and has a low electrical-power requirement. With a 2-volt maximum, the device is well within the human safety limit of 30 V, which is considered enough to deliver a substantial shock in some situations. Some of the possible applications mentioned by the authors include gustation tests, virtual grocery shopping, and immersive environments for exploring food flavors. However, the current system is limited to one hour of use due to gel depletion and it only supports a handful of flavor channels.

Future development aims to extend operation time, increase flavor complexity, and improve usability, marking the beginning of a new frontier for XR interfaces.

"At points there was fear the talks would implode, as groups representing vulnerable small island states and the least-developed countries walked out of negotiations Saturday," according to a new report from CNN.

But after weeks of international climate talks at COP29, "the world agreed to a new climate deal... "with wealthy countries pledging to provide $300 billion annually by 2035 to poorer countries to help them cope with the increasingly catastrophic impacts of the climate crisis." The amount pledged, however, falls far short of the $1.3 trillion economists say is needed to help developing countries cope with a climate crisis they have done least to cause — and there has been a furious reaction from many developing countries. a fiery speech immediately after the gavel went down, India's representative Chandni Raina slammed the $300 billion as "abysmally poor" and a "paltry sum," calling the agreement "nothing more than an optical illusion" and unable to "address the enormity of the challenge we all face."

Others were equally damning in their criticism. We are leaving with a small portion of the funding climate-vulnerable countries urgently need," said Tina Stege, Marshall Islands climate envoy. Stege heavily criticized the talks as showing the "very worst of political opportunism." Fossil fuel interests "have been determined to block progress and undermine the multilateral goals we've worked to build," she said in a statement...

There was also a push for richer emerging economies such as China and Saudi Arabia to contribute to the climate funding package, but the agreement only "encourages" developing countries to make voluntary contributions, and places no obligations on them... Saudi Arabia, the world's top oil exporter, which has pushed against ambitious action at past climate summits, seemed even more emboldened in Baku, publicly and explicitly rejecting any reference to oil, coal and gas in the deal.
The package "is also being criticised as short-sighted from the richer world's perspective," notes the BBC: The argument runs that if you want to keep the world safe from rising temperatures, then wealthier nations need to help emerging economies cut their emissions, because that is where 75% of the growth in emissions has occurred in the past decade.
But "Delegations more optimistic about the agreement said this deal is headed in the right direction," writes the Associated Press, "with hopes that more money flows in the future." The text included a call for all parties to work together using "all public and private sources" to get closer to the $1.3 trillion per year goal by 2035. That means also pushing for international mega-banks, funded by taxpayer dollars, to help foot the bill. And it means, hopefully, that companies and private investors will follow suit on channeling cash toward climate action. The agreement is also a critical step toward helping countries on the receiving end create more ambitious targets to limit or cut emissions of heat-trapping gases.

Instead of focusing on chatbots, a new study reveals an automated way to breach LLM-driven robots "with 100 percent success," according to IEEE Spectrum. "By circumventing safety guardrails, researchers could manipulate self-driving systems into colliding with pedestrians and robot dogs into hunting for harmful places to detonate bombs..." [The researchers] have developed RoboPAIR, an algorithm designed to attack any LLM-controlled robot. In experiments with three different robotic systems — the Go2; the wheeled ChatGPT-powered Clearpath Robotics Jackal; and Nvidia's open-source Dolphins LLM self-driving vehicle simulator. They found that RoboPAIR needed just days to achieve a 100 percent jailbreak rate against all three systems... RoboPAIR uses an attacker LLM to feed prompts to a target LLM. The attacker examines the responses from its target and adjusts its prompts until these commands can bypass the target's safety filters. RoboPAIR was equipped with the target robot's application programming interface (API) so that the attacker could format its prompts in a way that its target could execute as code. The scientists also added a "judge" LLM to RoboPAIR to ensure the attacker was generating prompts the target could actually perform given physical limitations, such as specific obstacles in the environment...

One finding the scientists found concerning was how jailbroken LLMs often went beyond complying with malicious prompts by actively offering suggestions. For example, when asked to locate weapons, a jailbroken robot described how common objects like desks and chairs could be used to bludgeon people.

The researchers stressed that prior to the public release of their work, they shared their findings with the manufacturers of the robots they studied, as well as leading AI companies. They also noted they are not suggesting that researchers stop using LLMs for robotics... "Strong defenses for malicious use-cases can only be designed after first identifying the strongest possible attacks," Robey says. He hopes their work "will lead to robust defenses for robots against jailbreaking attacks."
The article includes a reaction from Hakki Sevil, associate professor of intelligent systems and robotics at the University of West Florida. He concludes that the "lack of understanding of context of consequences" among even advanced LLMs "leads to the importance of human oversight in sensitive environments, especially in environments where safety is crucial." But a long-term solution could be LLMs with "situational awareness" that understand broader intent.

"Although developing context-aware LLM is challenging, it can be done by extensive, interdisciplinary future research combining AI, ethics, and behavioral modeling..."

The Trade Desk, one of the largest publicly traded advertising technology companies in the world, is building a connected television operating system. Axios reports: Existing OS providers, like Roku, Amazon's Fire TV and Google's Android TV, have a conflict of interest because they own content, [CEO and founder Jeff Green] said. Green believes that conflict of interest has muddled the advertising ecosystem for everyone. "We're looking at a concentration around a handful of players that lack objectivity," Green said. "We think we're in a unique position to make the ecosystem better." [...]

Ventura, a nod to the company's headquarters in Ventura, California, will be rolled out to the market in the second half of 2025, Green said. The company has been working to build the system quietly for three years. While some OS developers, such as Google, Amazon and Roku, have also developed their own hardware devices to service their operating systems, Green said The Trade Desk has "no intention of getting into the hardware business." Rather, it will partner with other hardware companies, such as smart TV manufacturers, as well as various television distributors, such as airlines, hotel chains, and gaming companies, to bring its OS to their devices.

Green believes hardware companies will be excited about the opportunity to partner because, in a competitive streaming environment, more hardware companies will need to build advertising businesses to scale. [...] Because The Trade Desk's goal is ultimately to improve a murky marketplace, Green said he isn't looking to make money from the OS directly. Ventura will be successful if it drives more pricing transparency and stronger measurement for the CTV advertising ecosystem writ large, he said. "Ultimately, the measure of success will be, do we have an ad auction that is so transparent that we can predict outcomes?" The Trade Desk will benefit financially from a more transparent ecosystem because it lacks a conflict of interest, Green said.

WhatsApp's newly unsealed court documents have exposed the extensive reach of NSO Group's Pegasus spyware operation, which targeted "between hundreds and tens of thousands" of devices, according to testimony from the company's head of research and development. The Israeli surveillance firm charged government customers up to $6.8 million for one-year licenses, generating at least $31 million in revenue in 2019 alone, TechCrunch first reported.

The documents detail previously unknown hacking tools named "Hummingbird," "Eden," and "Heaven," developed specifically to compromise WhatsApp users' devices. The revelations emerge from WhatsApp's ongoing 2019 lawsuit against NSO Group for alleged violations of U.S. anti-hacking laws.

The Belgian region of Flanders is rolling out personal data "pods" to 7 million citizens in a trial of World Wide Web inventor Tim Berners-Lee's vision for user-controlled data privacy.

Five Belgian hospitals have begun storing patient visit information in the data pods, developed by Berners-Lee's startup Inrupt over the past five years. The system aims to help compliance with European privacy regulations by giving citizens control over their personal information, from medical records to social media posts.

The initiative counters the current internet landscape dominated by major technology companies like Google and Meta, which store user data across their servers. Berners-Lee, who created the World Wide Web at CERN in 1989, advocates for returning data control to users through decentralized systems rather than leaving it vulnerable to harvesting by tech platforms and governments.

Economist: Britain has long been a pioneer in telecoms. In 1837 it built the world's first commercial telegraph; the first transatlantic call was placed from London in 1927; in 1992 a British programmer sent the first text message to a mobile phone. Today it lags rather than leads. According to figures provided to The Economist by Opensignal, a research firm, Britain ranks 46th for download speeds out of the 56 developed and developing countries for which there are data. That gives it the worst mobile service in the rich world.

Some of this is due to demand. Over the past three years data usage on mobile devices has doubled as people stream films and play games. The busiest parts of cities often lack mobile reception because the system is at capacity. But mainly it is an issue of supply. British users of 5G are only on it 11% of the time. That puts Britain 43rd out of the 56 countries. This lacklustre performance is caused by a combination of government U-turns, insufficient investment and sclerotic planning.

British telecom Virgin Media O2 has deployed an AI tool to combat phone scammers by wasting their time with fake conversations, the company said. The AI system, named Daisy, uses voice synthesis to mimic an elderly woman and engages fraudsters in lengthy discussions about fictitious family members or provides false bank details, keeping them occupied for up to 40 minutes per call.

Virgin Media O2 embedded phone numbers connected to Daisy within scammer call lists targeting vulnerable individuals. The system, developed with help from anti-scam YouTuber Jim Browning, automatically transcribes incoming calls and generates responses without human intervention.

Datacenter operators are increasingly turning to small modular reactors (SMRs) like those developed by Oklo to meet growing energy demands. According to The Register, Oklo has secured commitments from two major datacenter providers for 750 MW of power, pending regulatory approvals. It brings the firm's planned nuclear build-out to 2.1 gigawatts. From the report: Oklo's designs are, from what we understand, inspired by the Experimental Breeder Reactor II (EBR-II) and utilize liquid-metal cooling. They are capable of producing between 15MW and 50MW of power, depending on the configuration. That means Oklo's datacenter customers plan to deploy somewhere between 15 and 50 of the reactors to satisfy their thirst for electricity. However, they may be waiting a while.

According to Oklo's website, the nuclear startup hopes to bring its first plant online before the end of the decade. Before that can happen, though, Oklo will need to obtain approval from the Nuclear Regulatory Commission -- something for which it says it's already submitted applications. In 2022, the watchdog rejected an Oklo plan to build a small atomic reactor in Idaho, citing "significant information gaps" on safety-related measures.

That said, Oklo has lately received support from US government agencies including the Department of Energy (DoE), which has awarded a site use permit, while Idaho National Laboratory -- home of EBR-II -- has provided fuel material to support the efforts. Speaking of fuel, Oklo's designs may not suffer from the challenges other SMR startups, like Terrapower, have encountered. Oklo's designs are intended to run on recycled nuclear waste products from traditional reactors. In fact, the startup is currently working with DoE national labs to develop new fuel recycling technologies. Oklo hopes to bring a commercial-scale recycling plan online by the early 2030s.

Scientists have developed a method to reuse components from decommissioned data center servers, potentially reducing the carbon footprint of cloud computing infrastructure.

The research team from Microsoft, Carnegie Mellon University and the University of Washington demonstrated that older RAM modules and solid-state drives can be safely repurposed in new server builds without compromising performance, according to papers presented at recent computer architecture conferences.

When combined with energy-efficient processors, the prototype servers achieved an 8% reduction in total carbon emissions during Azure cloud service testing. Researchers estimate the approach could cut global carbon emissions by up to 0.2% if widely adopted. The cloud computing industry currently accounts for 3% of global energy consumption and could represent 20% of emissions by 2030, according to computing experts. Most data centers, including Microsoft's Azure, typically replace servers every 3-5 years.

South Korean researchers have developed a "morphing" wheel that can navigate stairs and obstacles up to 1.3 times its radius, potentially revolutionizing mobility devices and robotics.

The wheel, created by the Korea Institute of Machinery and Materials (KIMM), features a chain-based outer hoop and sensor-controlled spoke wires that adjust stiffness based on terrain. Inspired by water droplet mechanics, it transitions between solid and fluid states when encountering impediments.
