DOGE can’t use student loan data to dismantle the Education Dept., lawsuit says

Microsoft declined to comment, but allegedly the DOGE employees are “using AI software accessed through Microsoft’s cloud computing service Azure to pore over every dollar of money the department disburses, from contracts to grants to work trip expenses,” one source told the Post.

The lawsuit noted that several DOE employees have tried to block DOGE’s access by raising red flags up the command chain, but DOE leadership directly instructed lower-level employees to grant DOGE access, the same source alleged.

A big concern is that DOGE funneling education data into AI systems will cause sensitive data to be stored in a way that makes it more vulnerable to cyberattacks or data breaches. Another issue could be the AI system being error-prone or potentially hallucinating data that is driving decisions on major DOE cuts.

On Thursday, a DOE deputy assistant secretary for communications, Madi Biedermann, issued a statement insisting that DOGE employees are federal employees who have undergone background checks to be granted requisite security clearances.

“There is nothing inappropriate or nefarious going on,” Biedermann said.

Trump has similarly waved away concerns over DOGE’s work at DOE and other departments that officials worry are experiencing a “blitz” of seemingly unlawful power grabs, the Post reported. On Monday, Trump told reporters that “if there’s a conflict” with DOGE accessing Americans’ data, “then we won’t let him get near it.” But seemingly until Trump agrees there’s a conflict, Musk’s work with DOGE must go on, Trump said.

“We’re trying to shrink government, and he can probably shrink it as well as anybody else, if not better,” Trump suggested.

While thousands of Americans are suing, confused over whether they need to urgently protect their private financial data, one DOE staffer told the Post that DOGE “is working with almost unbelievable speed.” The staffer ominously suggested that it may already be too late to protect Americans from invasive probes or defend departments against cuts.

“They have a playbook, which is to get access to the data,” the staffer told the Post. “And once they’re in, it’s already over.”

The EV transition hits some snags at Porsche and Audi

Now Audi has gone a little further, abandoning its almost-new nomenclature in the process. As naming conventions go, Audi at least tried to keep things a little logical when it told everyone last summer that henceforth, odd-numbered Audis—A3, A5, Q5, Q7, and so on—would be internal combustion or hybrids, and even-numbered Audis—A4, A6, Q6, Q8—would be electric, or e-tron.

This was the case when we went to see some of those new Audis in the studio last summer. There was an all-new gasoline-powered A5, which comes in a handsome fastback sedan or even more handsome Avant (station wagon) version, that won’t come to the US.

There’s also an all-new, fully electric A6, available as a sedan but also as a handsome fastback sedan and even more handsome Avant. This one also isn’t coming to America.

As of this week, things are back to where they used to be. Forget the odd and even distinction; for now, it means nothing again. A gasoline-powered A6 will break cover on March 3, Audi says. And as for names? “A” means a low floor, and “Q” means a high floor (i.e., SUV or crossover).

The UK got rid of coal—where’s it going next?


Clean, but not fully green

The UK has transitioned to a lower-emission grid. Now comes the hard part.

With the closure of its last coal-fired power plant, Ratcliffe-on-Soar, on September 30, 2024, the United Kingdom has taken a significant step toward its net-zero goals. It’s no small feat to end the 142-year era of coal-powered electricity in the country that pioneered the Industrial Revolution. Yet the UK’s journey away from coal has been remarkably swift, with coal generation plummeting from 40 percent of the electricity mix in 2012 to just two percent in 2019, and finally to zero in 2024.

As of 2023, approximately half of UK electricity generation comes from zero-carbon sources, with natural gas serving as a transitional fuel. The UK aims to cut greenhouse gas emissions by 42 percent to 48 percent by 2027 and achieve net-zero by 2050. The government set a firm target to generate all of its electricity from renewable sources by 2040, emphasizing offshore wind and solar energy as the keys.

What will things look like in the intervening years, which will lead us from today to net-zero? Everyone’s scenario, even when based in serious science, boils down to a guessing game. Yet some things are more certain than others, the most important of these factors being the ones that are on solid footing beneath all of the guesswork.

Long-term goals

The closure of all UK coal-fired power stations in 2024 marked a crucial milestone in the nation’s decarbonization efforts. Coal was once the dominant source of electricity generation, but its contribution to greenhouse gas emissions made it a primary target for phase-out. The closure of these facilities has significantly reduced the UK’s carbon footprint and paved the way for cleaner energy sources.

With transition from coal, natural gas is set to play a crucial role as a “transition fuel.” The government’s “British Energy Security Strategy” argued that gas must continue to be an important part of the energy mix. It positioned gas as the “glue” that holds the electricity system together during the transition. Even the new Starmer government recognizes that, as the country progresses towards net-zero by 2050, the country may still use about a quarter of the gas it currently consumes.

Natural gas emits approximately half as much carbon dioxide as coal when combusted, making it a cleaner alternative during the shift to renewable energy sources. In 2022, natural gas accounted for around 40 percent of the UK’s electricity generation, while coal contributed less than two percent. This transition phase is deemed by the government to be essential as the country ramps up the capacity of renewable energy sources, particularly wind and solar power, to fill gaps left by the reduction of fossil fuels. The government aims to phase out natural gas that’s not coupled with carbon capture by 2035, but in the interim, it serves as a crucial bridge, ensuring energy security while reducing overall emissions.

But its role is definitely intended to be temporary; the UK’s long-term energy goal is to reduce reliance on all fossil fuels (starting with imported supplies), pushing for a rapid transition to cleaner, domestic sources of energy.

The government’s program has five primary targets:

  • Fully decarbonizing the power system (2035)
  • Ending the sale of new petrol and diesel cars (2035)
  • Achieving “Jet Zero” – net-zero UK aviation emissions (2050)
  • Creating 30,000 hectares of new woodland per year (2025)
  • Generating 50 percent of its total electricity from renewable sources by 2030

Offshore wind energy has emerged as this strategy’s key component, with significant investments being made in new wind farms. Favorable North Sea wind conditions have immense potential. In recent years, a surge in offshore wind investment has translated into several large-scale developments in advanced planning stages or now under construction.

The government has set a target to increase offshore wind capacity to 50 GW by 2030, up from around 10 GW currently. This initiative is supported by substantial financial commitments from both the public and private sectors. Recent investment announcements underscore the UK’s commitment to this goal and the North Sea’s central role in it. In 2023, the government announced plans to invest $25 billion (20 billion British pounds) in carbon capture and offshore wind projects in the North Sea over the next two decades. This investment is expected to create up to 50,000 jobs and help position the UK as a leader in clean energy technologies.

This was part of investments totaling over $166 million (133 million pounds) to support the development of new offshore wind farms, which are expected to create thousands of jobs and stimulate local economies.

In 2024, further investments were announced to support the expansion of offshore wind capacity. The government committed to holding annual auctions for new offshore wind projects to meet its goal of quadrupling offshore wind capacity by 2030. These investments are part of a broader strategy to leverage the UK’s expertise in offshore industries and transition the North Sea from an oil and gas hub to a clean-energy powerhouse.

Offshore wind

As the UK progresses toward its net-zero target, it faces both challenges and opportunities. While significant progress has been made in decarbonizing the power sector, the national government’s Climate Change Committee has noted that emissions reductions need to accelerate in other sectors, particularly agriculture, land use, and waste. However, with continued investment in renewable energy and supportive policies, the UK is positioning itself to become a leader in the global transition to a low-carbon economy.

Looking ahead, 2025 promises to be a landmark year for the UK’s green energy sector, with further investment announcements and projects in the pipeline.

The Crown Estate, which manages the seabed around England, Wales, and Northern Ireland, has made significant strides in facilitating new leases for offshore wind development. In 2023, the Crown Estate Scotland announced the successful auction of seabed leases for new offshore wind projects, totaling a capacity of 5 gigawatts. And in 2024, the government plans to hold its next major leasing round, which could see the deployment of an additional 7 GW of offshore wind capacity.

The UK government also approved plans for the Dogger Bank Wind Farm, which will be the world’s largest offshore wind farm when completed. Located off the coast of Yorkshire, this massive project will ultimately generate enough electricity to power millions of homes. Dogger is a joint venture linking SSE Renewables, Equinor, and Vattenfall.

This is in line with the government’s broader strategy to enhance energy independence and resilience, particularly in light of the geopolitical uncertainties affecting global energy markets. The UK’s commitment to renewable energy is not merely an environmental imperative; it is also an economic opportunity. By harnessing the vast potential of the North Sea, the UK aims not only to meet its net-zero targets but also to drive economic growth and job creation in the green energy sector, ensuring a sustainable future for generations to come.

Recognizing wind’s importance, the UK government launched a 2024 consultation on plans to develop a new floating wind energy sector.

The transition to a greener economy is projected to create up to 400,000 jobs by 2030 across various sectors, including manufacturing, installation, and maintenance of renewable energy technologies.

Its growing offshore wind industry is expected to attract billions in investment, solidifying the UK’s position as a leader in the global green energy market. The government’s commitment to offshore wind development, underscored by substantial investments in 2023 and anticipated announcements for 2024, signals a robust path forward.

Moving away from gas

Still, the path ahead remains challenging, requiring a multifaceted approach that balances economic growth, energy security, and environmental sustainability.

With the transition from coal, natural gas is now poised to play the central role as a bridge fuel. While natural gas emits fewer greenhouse gases than coal, it is still a fossil fuel and contributes to carbon emissions. However, in the short term, natural gas can help maintain energy security and provide a reliable source of electricity during periods of low renewable energy output. Additionally, natural gas can be used to produce hydrogen, potentially coupled with carbon capture, enabling a clean energy carrier that can be integrated into the existing energy infrastructure.

To support the country’s core clean energy goals, the government is implementing specific initiatives, although the pace has been quite uneven. The UK Emissions Trading Scheme (ETS) is being strengthened to incentivize industrial decarbonization. The government has also committed to investing in key green industries alongside offshore wind: carbon capture, usage and storage (CCUS), and nuclear energy.

Combined, these should allow the UK to limit its use of natural gas and capture the emissions associated with any remaining fossil fuel use.

While both countries are relying heavily on wind power, the UK’s energy-generation transformations are different from Germany’s. While both governments push to make some progress on the path to net-zero carbon emissions, their approaches and timelines differ markedly.

Energiewende, Germany’s energy transition, is characterized by what some critics consider to be overly ambitious goals for achieving net greenhouse gas neutrality by 2045. Those critics think that the words don’t come close to matching the required levels of either government or private sector financial commitment. Together with the Bundestag, the chancellor has set interim targets to reduce emissions by 65 percent by 2030 and 88 percent by 2040 (both compared to 1990 levels). Germany’s energy mix is heavily reliant on renewables, with a goal of sourcing 80 percent of its electricity from renewable energy by 2030—and achieving 100 percent by 2035.

However, Germany has faced challenges due to continued reliance on coal and natural gas, which made it difficult to reach its emissions goals.

The UK, however, appears to be ahead in terms of immediate reductions in coal use and the integration of renewables into its energy mix. Germany’s path is more complex, as it balances its energy transition with energy security concerns, particularly in light of how Russia’s war affects gas supplies.

DeepSeek is “TikTok on steroids,” senator warns amid push for government-wide ban

But while the national security concerns require a solution, Curtis said his priority is maintaining “a really productive relationship with China.” He pushed Lutnick to address how he plans to hold DeepSeek—and the CCP in general—accountable for national security concerns amid ongoing tensions with China.

Lutnick suggested that if he is confirmed (which appears likely), he will pursue a policy of “reciprocity,” where China can “expect to be treated by” the US exactly how China treats the US. Currently, China is treating the US “horribly,” Lutnick said, and his “first step” as Commerce Secretary will be to “repeat endlessly” that more “reciprocity” is expected from China.

But while Lutnick answered Curtis’ questions about DeepSeek somewhat head-on, he did not have time to respond to Curtis’ inquiry about Lutnick’s intentions for the US AI Safety Institute (AISI)—which Lutnick’s department would oversee and which could be essential to the US staying ahead of China in AI development.

Viewing AISI as key to US global leadership in AI, Curtis offered “tools” to help Lutnick give the AISI “new legs” or a “new life” to ensure that the US remains responsibly ahead of China in the AI race. But Curtis ran out of time to press Lutnick for a response.

It remains unclear how AISI’s work might change under Trump, who revoked Joe Biden’s AI safety rules establishing the AISI.

What is clear is that lawmakers are being pressed to preserve and even evolve the AISI.

Yesterday, the chief economist for a nonprofit called the Foundation for the American Innovation, Samuel Hammond, provided written testimony to the US House Science, Space, and Technology Committee, recommending that AISI be “retooled to perform voluntary audits of AI models—both open and closed—to certify their security and reliability” and to keep America at the forefront of AI development.

“With so little separating China and America’s frontier AI capabilities on a technical level, America’s lead in AI is only as strong as our lead in computing infrastructure,” Hammond said. And “as the founding member of a consortium of 280 similar AI institutes internationally, the AISI seal of approval would thus support the export and diffusion of American AI models worldwide.”

H5N1 bird flu spills over again; Nevada cows hit with different, deadly strain

The spread of H5N1 bird flu in dairy cows is unprecedented; the US outbreak is the first of its kind in cows. Virologists and infectious disease experts fear that the continued spread of the virus in domestic mammals like cows, which have close interactions with people, will provide the virus countless opportunities to spill over and adapt to humans.

So far, the US has tallied 67 human cases of H5N1 since the start of 2024. Of those, 40 have been in dairy workers, while 23 were in poultry workers, one was the Louisiana case who had contact with wild and backyard birds, and three were cases that had no clear exposure.

Whether the D1.1 genotype will pose a yet greater risk for dairy workers remains unclear for now. Generally, H5N1 infections in humans have been rare but dangerous. According to data collected by the World Health Organization, 954 H5N1 human cases have been documented globally since 2003. Of those, 464 were fatal, for a fatality rate among documented cases of 49 percent. But, so far, nearly all of the human infections in the US have been relatively mild, and experts don’t know why. There are various possible factors, including transmission route, past immunity of workers, use of antivirals, or something about the B3.13 genotype specifically.

For now, the USDA says that the detection of the D1.1 genotype in cows doesn’t change their eradication strategy. It further touted the finding as a “testament to the strength of our National Milk Testing Strategy.”

Robocallers posing as FCC staff blocked after robocalling real FCC staff


A not-very-successful robocall scheme

You can ignore robocalls from FCC “Fraud Prevention Team,” which doesn’t exist.

Robocallers posing as employees of the Federal Communications Commission made the mistake of trying to scam real employees of the FCC, the FCC announced yesterday. “On the night of February 6, 2024, and continuing into the morning of February 7, 2024, over a dozen FCC staff and some of their family members reported receiving calls on their personal and work telephone numbers,” the FCC said.

The calls used an artificial voice that said, “Hello [first name of recipient] you are receiving an automated call from the Federal Communications Commission notifying you the Fraud Prevention Team would like to speak with you. If you are available to speak now please press one. If you prefer to schedule a call back please press two.”

You may not be surprised to learn that the FCC does not have any “Fraud Prevention Team” like the one mentioned in the robocalls, and especially not one that demands Google gift cards in lieu of jail time.

“The FCC’s Enforcement Bureau believes the purpose of the calls was to threaten, intimidate, and defraud,” the agency said. “One recipient of an imposter call reported that they were ultimately connected to someone who ‘demand[ed] that [they] pay the FCC $1,000 in Google gift cards to avoid jail time for [their] crimes against the state.'”

The FCC said it does not “publish or otherwise share staff personal phone numbers” and that it “remains unclear how these individuals were targeted.” Obviously, robocallers posing as FCC employees probably wouldn’t intentionally place scam calls to real FCC employees. But FCC employees are just as likely to get robocalls as anyone else. This set of schemers apparently only made about 1,800 calls before their calling accounts were terminated.

The FCC described the scheme yesterday when it announced a proposed fine of $4,492,500 against Telnyx, the voice service provider accused of carrying the robocalls. The FCC alleges that Telnyx violated “Know Your Customer (KYC)” rules by providing access to calling services without verifying the customers’ identities. When contacted by Ars today, Telnyx denied the FCC’s allegations and said it will contest the proposed fine.

The “MarioCop” accounts

The robocalling scheme lasted two days. On February 6, 2024, Telnyx accepted two new customers calling themselves Christian Mitchell and Henry Walker, who provided street addresses in Toronto and email addresses with the domain name “mariocop123.com.” The robocallers apparently used fake identities and paid for Telnyx service in Bitcoin.

The Telnyx customers who placed the robocalls are referred to as “MarioCop accounts” in the FCC’s Notice of Apparent Liability for Forfeiture (NAL) issued against Telnyx. Telnyx flagged one of the accounts in the course of its “routine examination of new users” and terminated the account on February 7 after determining the calls violated its terms and conditions and acceptable use policy. Telnyx also reported the account to the FCC.

Telnyx is based in Chicago. It offers a service that lets callers “build a custom AI voice bot” and a voice API that “makes it simple to make, receive and control voice calls with code.” Telnyx is also a VoIP provider that says it “holds carrier status in 30+ countries around the world” and offers “local calling in over 80 countries and PSTN [Public Switched Telephone Network] replacement in 45+ markets.”

The FCC subpoenaed Telnyx for information about the calls, and the resulting records showed that one MarioCop account placed 1,029 calls between February 6 and February 7. The other account placed 768 calls on February 6.

The FCC also subpoenaed Telnyx for information that might identify the callers and “determined that the very limited identifying information Telnyx collected from its customers was false.” They used physical addresses in Canada, including one that turned out to be a Sheraton hotel, and IP addresses from Scotland and England.

“The @mariocop123.com domain is not associated with any known business; a website using the same domain was created in February 2024 and remains undeveloped,” the FCC said. The FCC notes that both MarioCop accounts may have been operated by the same person.

FCC: Telcos must know their customers

Telnyx “accepted the names and physical addresses at face value, without any further requests for corroboration or independent verification,” the FCC forfeiture order said. Neither applicant provided a telephone number.

The FCC alleged that Telnyx didn’t do enough “to discern whether the limited amount of identifying information its customer provided was legitimate and it overlooked obvious discrepancies in the information it collected… Becoming Telynyx’s customer and gaining access to outbound calling services that allowed origination of hundreds of calls (more than 1,000 calls from the First MarioCop Account) was as simple as making up a fake name and address and acquiring a non-free email address.”

The FCC notice continued:

Our rules require Telnyx to know its customers. Yet it did not know who the MarioCop Account holders were. We therefore conclude that Telnyx apparently violated section 64.1200(n)(4) of our rules by allowing the First MarioCop Account and the Second MarioCop Account access to outbound calling services without actually knowing the true identities of the account holders. By extension, we believe we could likely find that Telnyx apparently violated our rules with regards to every customer it onboarded using the same process as it did for the MarioCop Accounts. We decline to do so here absent further investigation.

Telnyx will have an opportunity to respond to the allegations and argue that it shouldn’t be fined. In some cases, the FCC and the telecom reach a settlement for a lower amount.

Telnyx CEO David Casem told Ars today that “Telnyx is surprised by the FCC’s mistaken decision to issue a Notice of Apparent Liability stating an intent to impose monetary penalties. The Notice of Apparent Liability is factually mistaken, and Telnyx denies its allegations. Telnyx has done everything and more than the FCC has required for Know-Your-Customer (‘KYC’) and customer due diligence procedures.”

We also sent a message to the email addresses used by the MarioCop accounts and will update this article in the unlikely event that we receive a response.

Telnyx defends response, citing quick shutdown

Casem said the FCC hasn’t previously demanded “perfection” in stopping illegal traffic. “Since bad actors continuously find ways to avoid detection, the FCC has historically expected providers to take reasonable steps to detect and block them,” he told Ars. “Yet the FCC now seeks to impose substantial monetary penalties on Telnyx for limited unlawful calling activity that Telnyx not only did not originate but swiftly blocked within a matter of hours.”

Casem said that “there has been no allegation of subsequent recurring activity” and urged the FCC to “reconsider what can only be viewed as an improper effort to impose an unprecedented zero-tolerance requirement on providers through enforcement action, in the absence of any defined rules informing providers what is expected of them.”

FCC Chairman Brendan Carr said in yesterday’s announcement that he is pleased with the “bipartisan vote in favor of this nearly $4.5 million proposed fine” and that it “continues the FCC’s longstanding work to stop bad actors.”

Anna Gomez, a Democratic member of the FCC, said that Carr’s office accepted her request for a change designed to encourage telecoms to report potential violations to the FCC. “It is important that service providers work quickly and closely with the FCC to identify and stop illegal traffic before it makes its way to consumers. I value self-reporting from industry actors on potential violations of our rules, and I am grateful the Office of Chairman Carr accepted our edits to this NAL to encourage self-reporting,” Gomez said.

There was a dissenting vote from Republican Commissioner Nathan Simington, but not because of the facts specific to this case. Because of a recent Supreme Court ruling limiting the power of federal agencies, Simington has vowed to vote against any fine imposed by the commission until its legal powers are clear.

“While the conduct described in this NAL is particularly egregious and certainly worth enforcement action, I continue to believe that the Supreme Court’s decision in Jarkesy prevents me from voting, at this time, to approve this or any item purporting to impose a fine,” Simington said.

polestar-ceo-says-the-brand’s-tech-makes-the-us-a-“great-market-for-us”

Polestar CEO says the brand’s tech makes the US a “great market for us”

Being an EV-only brand in 2025 looks to be a harder job than once anticipated, and for Polestar that’s doubly hard given the company is owned by China’s Geely, and therefore highly exposed to a string of recent protectionist moves by the US Congress and successive administrations to limit US exposure to Chinese automakers and their suppliers.

Lohscheller didn’t sound particularly pessimistic when we spoke earlier this week, though. “The US in general is a big market in terms of size. I think customers like emission-free mobility. They like also technology. And I think Polestar is much more than just [an] EV. We have so much technology in the cars,” he said.

Referring to the Polestar 3, “It’s the first European Software Defined vehicle, right? So not only can we do the over-the-air bit, we can make the car better every day. And I mean, the German OEMs come probably in four years’ time,” Lohscheller said.

As for the new landscape of tariffs and software bans? “I always think it’s important to have clarity on things,” he said. Now that the impending ban on Chinese connected-car software is on the books, Polestar has begun looking for new suppliers for its US-bound cars to ensure they’re compliant when it goes into effect sometime next year.

“But our US strategy is very clear. We manufacture locally here. That makes a lot of sense. I think we have great products for the US market… I see a renaissance of the dealers. Many people are saying ‘direct [sales] is the way to go, that’s the solution of everything.’ I don’t think it is. It is an option, an alternative, but I think dealers, being close to your customers, offer the service, and we have an excellent network here,” he said.

Drones are now launching drones to attack other drones in Ukraine

Radio mast

The Ukrainian military is talking up a new ground drone called the Pliushch, which doesn’t carry a weapon but instead features a folded, 10-meter (32-foot) tall radio mast. The drone has a range of 40 km (25 miles), and once in position, it can raise the radio mast, which can be used either as a communications repeater or as a mobile electronic warfare station.

The future of drone combat

These examples are really just a partial list—it doesn’t even touch on the continually updated naval drones that Ukraine continues to deploy in the Black Sea—and for every new innovation, there will shortly be a counter-innovation. Case in point: electronic warfare has now saturated front-line combat areas in Ukraine and Russia and, in some places, is so bad that fiber optic drones are now used to avoid its effects. (These drones unspool miles of ultra-thin fiber-optic cable behind them as they fly, which provides a high-quality, unjammable video and control channel to the drone.)

Because fiber optic drones lack the electromagnetic transmissions that can make drones easy to pinpoint, new methods (including short-range radar systems) are now used to hunt them down, while quick-reaction units will use small attack drones to hit the fiber optic drone before it reaches its target.

Given the many kinds of drone hardware available, you might wonder why more assaults don’t rely on machines rather than humans. Now that ground drones are entering the fight in greater numbers, this does appear to be happening. For instance, local news reports from Ukraine in December described how the Khartia brigade of the Ukrainian National Guard attacked Russian positions using only a mix of machine gun ground drones, aerial attack drones, and mine-laying/clearing drones.

framework-laptop’s-risc-v-board-for-open-source-diehards-is-available-for-$199

Framework Laptop’s RISC-V board for open source diehards is available for $199

We’ve covered the Framework Laptop 13 primarily as a consumer Windows laptop, reviewing versions with multiple Intel and AMD processors. But the system’s modular nature makes it possible to expand it beyond Windows PC hardware, as we’ve seen with experiments like the (now-discontinued) Chromebook Edition of the laptop.

Today Framework is expanding to something even more experimental: a DeepComputing RISC-V Mainboard targeted primarily at developers. RISC-V is a fully open source and royalty-free instruction set, making it possible for anyone to adopt and use it without having to license it (unlike x86, which is a maze of cross-licensed Intel and AMD technologies that other companies can’t really buy into; or Arm, which is licensed by the company of the same name).

First announced in June 2024, the board is available to order today for $199. The board is designed to fit in a Framework Laptop 13 chassis, which means that people who would prefer a desktop can also put it into the $39 Cooler Master Mainboard Case that Framework offers.

Made in concert with DeepComputing, the board uses a StarFive JH7110 processor with four 1.5 GHz SiFive U74 CPU cores. The board can officially run either Ubuntu 24.04 LTS or Fedora 41, with tech support provided by DeepComputing.

The RISC-V board isn’t being offered in a pre-built laptop, but Framework is also introducing a barebones boardless $399 laptop chassis with a screen, 55 WHr battery, speakers, and a keyboard for $399. It can be used for the RISC-V Mainboard or any other Framework Laptop 13 motherboard model.

The Mercedes-AMG GT 63 S E Performance is quite a name, quite a car

The powertrain has been tuned for power delivery, not maximum efficiency—that isn’t the job of a car wearing the AMG badge—and has an almost-dizzying amount of drive modes, suspension settings, and levels of battery regeneration, all configurable from Mercedes’ flat UI infotainment system that can be a little busy to look at but which remains very intuitive (and comes with rather excellent voice recognition). In fact, this might be the least-distracting implementation of MBUX I’ve encountered so far.

When you first start the AMG GT 63 S, it defaults to electric mode, as long as the battery has some charge in it. Top speed is capped at 87 mph (140 km/h), and the electric motor has more than enough torque to make using this mode perfectly pleasant. Your neighbors will appreciate the silence as you leave in the morning, too. There are three levels of lift-off regen, up to the highest setting, which is a one-pedal driving mode.

Comfort fires up the V8 as necessary but will defer to the electric motor whenever possible. It upshifts the nine-speed transmission early, and with the dampers set to Comfort as well, this is the mode you’d use with passengers on board. Because the car is meant to be a performance hybrid, the powertrain will use spare engine power to recharge the battery pack whenever it can and will fully charge the pack in about 30 minutes of driving.

One mode maintains the battery’s state of charge, another is for slippery conditions, and then there’s Sport, Sport+, and Race. These offer escalating levels of performance, with more boost from the electric motor supplementing the raucous V8, faster shift times from the transmission, sharper throttle maps, and more regenerative braking. Finally, there’s an individual mode for you to pick your own settings.

It’s the “hydrophilic capillary-enhanced adhesion”of gecko feet that most interested the authors of this latest paper. Per the World Health Organization, 684,000 people die and another 38 million are injured every year in slips and falls, with correspondingly higher health care costs. Most antislip products (crampons, chains, studs, cleats), tread designs, or materials (fiberglass, carbon fiber, rubber) are generally only effective for specific purposes or short periods of time. And they often don’t perform as well on wet ice, which has a nanoscale quasi-liquid layer (QLL) that makes it even more slippery.

So Vipin Richhariya of the University of Minho in Portugal and co-authors turned to gecko toe pads (as well as those of toads) for a better solution. To get similar properties in their silicone rubber polymers, they added zirconia nanoparticles, which attract water molecules. The polymers were rolled into a thin film and hardened, and then a laser etched groove patterns onto the surface—essentially creating micro cavities that exposed the zirconia nanoparticles, thus enhancing the material’s hydrophilic effects.

Infrared spectroscopy and simulated friction tests revealed that the composites containing 3 percent and 5 percent zirconia nanoparticles were the most slip-resistant. “This optimized composite has the potential to change the dynamics of slip-and-fall accidents, providing a nature-inspired solution to prevent one of the most common causes of accidents worldwide,” the authors concluded. The material could also be used for electronic skin, artificial skin, or wound healing.

Concern about SpaceX influence at NASA grows with new appointee

Like a lot of the rest of the federal government right now, NASA is reeling during the first turbulent days of the Trump administration.

The last two weeks have brought a change in leadership in the form of interim administrator Janet Petro, whose ascension was a surprise. Her first act was to tell agency employees to remove diversity, equity, inclusion, and accessibility contracts and to “report” on anyone who did not carry out this order. Soon, civil servants began receiving emails from the US Office of Personnel Management that some perceived as an effort to push them to resign.

Then there are the actions of SpaceX founder Elon Musk. Last week he sowed doubt by claiming NASA had “stranded” astronauts on the space station. (The astronauts are perfectly safe and have a ride home.) Perhaps more importantly, he owns the space agency’s most important contractor and, in recent weeks, has become deeply enmeshed in operating the US government through his Department of Government Efficiency. For some NASA employees, whether or not it is true, there is now an uncomfortable sense that they are working for Musk and to dole out contracts to SpaceX.

This concern was heightened late Friday when Petro announced that a longtime SpaceX employee named Michael Altenhofen had joined the agency “as a senior advisor to the NASA Administrator.” Altenhofen is an accomplished engineer who interned at NASA in 2005 but has spent the last 15 years at SpaceX, most recently as a leader of human spaceflight programs. He certainly brings expertise, but his hiring also raises concerns about SpaceX’s influence over NASA operations. Petro did not respond to a request for comment on Monday about potential conflicts of interest and the scope of Altenhofen’s involvement.

I spent this weekend talking and texting with NASA sources at various centers around the country, and the overriding message is that morale at the agency is “absurdly low.” Meetings between civil servants and their leadership, such as an all-hands gathering at NASA’s Langley Research Center in Virginia recently, have been fraught with tension. No one knows what will happen next.
