"SpaceX founder Elon Musk has said his Starship rocket will head to Mars by the end of next year," writes the BBC, "as the company investigates several recent explosions in flight tests." Human landings could begin as early as 2029 if initial missions go well, though "2031 was more likely", he added in a post on his social media platform X...

The billionaire said in 2020 that he remained confident that his company would land humans on Mars six years later. In 2024, he said he would launch the first Starships to Mars in 2026, with plans to send crewed flights in four years.

Musk has said that the coming Mars mission would carry the Tesla humanoid robot "Optimus", which was shown to the public last year.

An anonymous reader quotes a report from 404 Media: Last week, Aix Marseille University, France's largest university, invited American scientists who believe their work is at risk of being censored by Donald Trump administration's anti-science policies to continue their research in France. Today, the university announced that it is already seeing great interest from scientists at NASA, Yale, Stanford, and other American schools and government agencies, and that it wants to expand the program to other schools and European countries to absorb all the researchers who want to leave the United States. "We are witnessing a new brain drain," Eric Berton, Aix Marseille University's president, said in a press release. "We will do everything in our power to help as many scientists as possible continue their research. However, we cannot meet all demands on our own. The Ministry of Education and Research is fully supporting and assisting us in this effort, which is intended to expand at both national and European levels."

The press release from the university claims that researchers from Stanford, Yale, NASA, the National Institute of Health, George Washington University, "and about 15 other prestigious institutions," are now considering "scientific exile." More than 40 American scientists have expressed interest in the program, it said. Their key research areas are "health (LGBT+ medicine, epidemiology, infectious diseases, inequalities, immunology, etc.), environment and climate change (natural disaster management, greenhouse gases, social impact, artificial intelligence), humanities and social sciences (communication, psychology, history, cultural heritage), astrophysics."

"The current Executive Orders have led to a termination of one of my research grants. While it was not a lot of money, it was a high profile, large national study," one researcher who has reached out to Aix Marseille University in order to take advantage of the program told me. 404 Media granted the researcher anonymity because speaking about the program might jeopardize their current position at a leading American university. "While I have not had to lay off staff as a result of that particular cancellation, I will have to lay off staff if additional projects are terminated. Everything I focus on is now a banned word." The program, called "Safe Place for Science," initially will fund 15 researchers with 15 million Euros. Aix Marseille University says that it is already working closely with the regional government and France's Chamber of Commerce and Industry "to facilitate the arrival of these scientists and their families in the region, offering support with employment, housing, school access, transportation, and visas." "We are doing what is necessary to provide them with the best living environment. We are ready to welcome them and will make them true children of the country!" Renaud Muselier, President of the Regional Council of Provence-Alpes-Cote d'Azur, said in a statement.

An anonymous reader quotes a report from Ars Technica: Meta plans to test out X's algorithm for Community Notes to crowdsource fact-checks that will appear across Facebook, Instagram, and Threads. In a blog, Meta said the testing in the U.S. would begin March 18, with about 200,000 potential contributors already signed up. Anyone over 18 with a Meta account more than six months old can also join a waitlist of users who will "gradually" and "randomly" be admitted to write and rate cross-platform notes during initial beta testing.

Meta claimed that borrowing X's approach would result in "less biased" fact-checking than relying on experts alone. But the social media company will delay publicly posting any notes until it's confident that the system is working. For users of Meta platforms, notes could help flag misleading content overlooked by prior fact-checking efforts. However, Meta confirmed that users will not be allowed to add notes correcting misleading advertisements, which means notes won't help reduce scam ads that The Guardian reported last August have been spreading on Facebook for years. Meta confirmed that the company plans to tweak X's algorithm over time to develop its own version of community notes, which "may explore different or adjusted algorithms to support how Community Notes are ranked and rated."

Parents who are worried about their children being on Roblox should not let them use it, the chief executive of the gigantic gaming platform has said. From a report: The site, which is the most popular in the UK among young gamers aged eight to 12, has been dogged by claims of some children being exposed to explicit or harmful content through its games, alongside multiple reported allegations of bullying and grooming.

But its co-founder and CEO Dave Baszucki insisted that the company is vigilant in protecting its users and pointed out that "tens of millions" of people have "amazing experiences" on the site. When asked what his message is to parents who don't want their children on the platform, Mr Baszucki said: "My first message would be, if you're not comfortable, don't let your kids be on Roblox." [...] "That sounds a little counter-intuitive, but I would always trust parents to make their own decisions," he told BBC News in an exclusive interview.

An anonymous reader quotes a report from the BBC: A former senior Facebook executive has told the BBC how the social media giant worked "hand in glove" with the Chinese government on potential ways of allowing Beijing to censor and control content in China. Sarah Wynn-Williams -- a former global public policy director -- says in return for gaining access to the Chinese market of hundreds of millions of users, Facebook's founder, Mark Zuckerberg, considered agreeing to hiding posts that were going viral, until they could be checked by the Chinese authorities.

Ms Williams -- who makes the claims in a new book -- has also filed a whistleblower complaint with the US markets regulator, the Securities and Exchange Commission (SEC), alleging Meta misled investors. The BBC has reviewed the complaint. Facebook's parent company Meta, says Ms Wynn-Williams had her employment terminated in 2017 "for poor performance." It is "no secret we were once interested" in operating services in China, it adds. "We ultimately opted not to go through with the ideas we'd explored." Meta referred us to Mark Zuckerberg's comments from 2019, when he said: "We could never come to agreement on what it would take for us to operate there, and they [China] never let us in."

Facebook also used algorithms to spot when young teenagers were feeling vulnerable as part of research aimed at advertisers, Ms Wynn-Williams alleges. A former New Zealand diplomat, she joined Facebook in 2011, and says she watched the company grow from "a front row seat." Now she wants to show some of the "decision-making and moral compromises" that she says went on when she was there. It is a critical moment, she adds, as "many of the people I worked with... are going to be central" to the introduction of AI. In her memoir, Careless People, Ms Wynn-Williams paints a picture of what she alleges working on Facebook's senior team was like.

Former Google CEO Eric Schmidt has taken control of rocket startup Relativity Space, replacing co-founder Tim Ellis as CEO and significantly funding the company's development of its medium-lift rocket, Terran R. The New York Times first reported (paywalled) the news. Ars Technica reports: Schmidt's involvement with Relativity has been quietly discussed among space industry insiders for a few months. Multiple sources told Ars that he has largely been bankrolling the company since the end of October, when the company's previous fundraising dried up. It is not immediately clear why Schmidt is taking a hands-on approach at Relativity. However, it is one of the few US-based companies with a credible path toward developing a medium-lift rocket that could potentially challenge the dominance of SpaceX and its Falcon 9 rocket. If the Terran R booster becomes commercially successful, it could play a big role in launching megaconstellations.

Schmidt's ascension also means that Tim Ellis, the company's co-founder, chief executive, and almost sole public persona for nearly a decade, is now out of a leadership position. "Today marks a powerful new chapter as Eric Schmidt becomes Relativity's CEO, while also providing substantial financial backing," Ellis wrote on the social media site X. "I know there's no one more tenacious or passionate to propel this dream forward. We have been working together to ensure a smooth transition, and I'll proudly continue to support the team as Co-founder and Board member." Relativity also on Monday released a video outlining the development of the Terran R rocket and the work required to reach the launch pad.

According to the video, the first "flight" version of the Terran R rocket will be built this year, with tentative plans to launch from a pad at Cape Canaveral, Florida, in 2026. "The company aims to soft land the first stage of the first launch in the Atlantic Ocean," adds Ars. "However, the 'Block 1' version of the rocket will not fly again."

"Full reuse of the first stage will be delayed to future upgrades. Eventually, the Relativity officials said, they intend to reach a flight rate of 50 to 100 rockets a year with the Terran R when the vehicle is fully developed."

An anonymous reader quotes a report from TechCrunch: When Bluesky CEO Jay Graber walked on stage at SXSW 2025 for her keynote discussion, she wore a large black T-shirt with her hair pulled back into a bun. At first glance, it might appear as though she's following the same playbook that so many women in tech leadership have played before: downplaying her femininity to be taken seriously. The truth is way more interesting than that. What might look like your average black T-shirt is a subtle, yet clear swipe at Mark Zuckerberg, a CEO who represents everything that Bluesky is trying to work against as an open source social network.

The Meta founder and CEO has directly compared himself to the Roman emperor Julius Caesar. His own shirt declared Aut Zuck aut nihil, which is a play on the Latin phrase aut Caesar aut nihil: "Either Caesar or nothing." Graber's shirt -- which directly copies the style of a shirt that Zuckerberg wore onstage recently -- says Mundus sine caesaribus. Or, "a world without Caesars." With the way Bluesky is designed, Graber is certainly putting her money where her mouth (or shirt) is. As a decentralized social network built upon an open source framework, Bluesky differs from legacy platforms like Facebook in that users have a direct, transparent window into how the platform is being built. "If a billionaire came in and bought Bluesky, or took it over, or if I decided tomorrow to change things in a way that people really didn't like, then they could fork off and go on to another application," Graber explained at SXSW. "There's already applications in the network that give you another way to view the network, or you could build a new one as well. And so that openness guarantees that there's always the ability to move to a new alternative."

Internet shutdowns in Africa hit a record high in 2024, with 21 shutdowns across 15 countries. The previous record was 19 shutdowns in 2020 and 21. The Guardian reports: Authorities in Comoros, Guinea-Bissau and Mauritius joined repeat offenders such as Burundi, Ethiopia, Equatorial Guinea and Kenya. Guinea, Nigeria, Senegal and Tanzania were also on the list. But perpetrators also included militias and other non-state actors. Telecommunication and internet service providers who shut services based on government orders are also complicit in violating people's rights, said Felicia Anthonio, the #KeepItOn campaign manager at Access Now, citing the UN guiding principles on business and human rights.

The details showed that most of the shutdowns were imposed as a response to conflicts, protests and political instability. There were also restrictions during elections. [...] At least five shutdowns in Africa had been imposed for more than a year by the end of 2024, according to Access Now. As of early 2025, the social network Meta was still restricted in Uganda, despite authorities engaging with its representatives. On the Equatorial Guinean island of Annobon, internet and cell services have been cut off since an August 2024 protest over environmental concerns and isolation from the rest of the country. The increase in shutdowns led the African Commission on Human and Peoples' Rights to pass a landmark resolution in March 2024 to help reverse the trend.

An anonymous reader shares a Nature story: In March last year, researchers found that among a group of nearly 300 participants, people who had higher concentrations of plastics in deposits of fat in their arteries (arterial plaques) were more likely to experience heart attacks or strokes, and more likely to die as a result, than those in whom plastics were not detected. Since it was published, the New England Journal of Medicine study has been mentioned more than 6,600 times on social media and more than 800 times in news articles and blogs.

The issue of whether plastics are entering human tissues and what impacts they might have on health is understandably of great interest to scientists, industry and society. Indeed, for the past few years there have been news stories almost every month about peer-reviewed articles that have reported findings of plastic particles in all sorts of human tissues and bodily fluids -- including the lungs, heart, penis, placenta and breast milk. And in multiple countries, policymakers are being urged to implement measures to limit people's exposure to nanoplastics and microplastics.

Many of the studies conducted so far, however, rely on small sample sizes (typically 20-50 samples) and lack appropriate controls. Modern laboratories are themselves hotspots of nanoplastic and microplastic pollution, and the approaches that are being used to detect plastics make it hard to rule out the possibility of contamination, or prove definitively that plastics are in a sample. Also, many findings are not biologically plausible based on what is known -- mainly from nanomedicine -- about the movement of tiny particles within the human body.

For an emerging area of research, such problems are unsurprising. But without more rigorous standards, transparency and collaboration -- among researchers, policymakers and industrial stakeholders -- a cycle of misinformation and ineffective regulation could undermine efforts to protect both human health and the environment.

The Washington Post reports: Meta was willing to go to extreme lengths to censor content and shut down political dissent in a failed attempt to win the approval of the Chinese Communist Party and bring Facebook to millions of internet users in China, according to a new whistleblower complaint from a former global policy director at the company.

The complaint by Sarah Wynn-Williams, who worked on a team handling China policy, alleges that the social media giant so desperately wanted to enter the lucrative China market that it was willing to allow the ruling party to oversee all social media content appearing in the country and quash dissenting opinions. Meta, then called Facebook, developed a censorship system for China in 2015 and planned to install a "chief editor" who would decide what content to remove and could shut down the entire site during times of "social unrest," according to a copy of the 78-page complaint exclusively seen by The Washington Post.

Meta chief executive Mark Zuckerberg also agreed to crack down on the account of a high-profile Chinese dissident living in the United States following pressure from a high-ranking Chinese official the company hoped would help them enter China, according to the complaint, which was filed in April to the Securities and Exchange Commission [SEC]. When asked about its efforts to enter China, Meta executives repeatedly "stonewalled and provided nonresponsive or misleading information" to investors and American regulators, according to the complaint.

Wynn-Williams bolstered her SEC complaint with internal Meta documents about the company's plans, which were reviewed by The Post. Wynn-Williams, who was fired from her job in 2017, is also scheduled to release a memoir this week documenting her time at the company, titled "Careless People: A Cautionary Tale of Power, Greed, and Lost Idealism." According to a memo in the complaint, Meta leaders faced aggressive pressure by Chinese government officials to host Chinese users' data to local data centers, which Wynn-Williams alleges would have made it easier for the Chinese Communist Party to covertly obtain the personal information of its citizens.
Wynn-Williams told the Washington Post that "for many years Meta has been working hand in glove with the Chinese Communist Party, briefing them on the latest technological developments and lying about it."

Reached for a comment, Meta spokesman Andy Stone told the Washington Post it was "no secret" they'd been interested in operating in China. "This was widely reported beginning a decade ago. We ultimately opted not to go through with the ideas we'd explored, which Mark Zuckerberg announced in 2019." Although the Post shares new details about what a Facebook privacy policy staffer offer China in negotations in 2014. ("In exchange for the ability to establish operations in China, FB will agree to grant the Chinese government access to Chinese users' data — including Hongkongese users' data.")

The Post also describes one iteration of a proposed agreement in 2015. "To aid the effort, Meta built a censorship system specially designed for China to review, including the ability to automatically detect restricted terms and popular content on Facebook, according to the complaint...

"In 2017, Meta covertly launched a handful of social apps under the name of a China-based company created by one of its employees, according to the complaint."

Nominated for 10 Oscars, The Brutalist (directed and produced by Brady Corbet) has an "intriguing and controversial technical feature," according to the Baffler, that threatens to turn movie-viewing into "a drab appreciation of machine-managed flawlessness, and acting less interesting..." In January, the film's editor Dávid Jancsó revealed that he and Corbet used tools from AI speech software company Respeecher to make the Hungarian-language dialogue spoken by Adrien Brody (who plays the protagonist, Hungarian émigré architect László Tóth) and Felicity Jones (who plays Tóth's wife Erzsébet) sound more Hungarian. In response to the ensuing backlash, Corbet clarified that the actors worked "for months" with a dialect coach to perfect their accents; AI was used "in Hungarian language dialogue editing only, specifically to refine certain vowels and letters for accuracy...." Defenders of this slimy deception claim the use of AI in film is no different than CGI or automated dialogue replacement, tools commonly deployed in the editing suite for picture and audio enhancement. But CGI and ADR don't tamper with the substance of a performance, which is what's at issue here....

AI seems poised to decimate the voice acting industry; how long will it be before filmmakers give up on the whole time-wasting business of dialect coaching and language research and toss their performers' untrained vocalizations directly into the linguistic Instant Pot...? "Adrien and Felicity's performances are completely their own," Corbet has argued. Only, they're not. Brody and Jones's performances may now be authentic to spoken Hungarian, but they're no longer authentic to themselves: at least in the parts of the film with Hungarian dialogue, the acting stands more as a monument to the prowess of the voice-matching software than that of the actors...

AI is a different beast from color film, or the Louma crane, or the hand-held camera: it's steroidal, aesthetically corrupting, and unlike these earlier advances it confronts the filmmaker with real ethical questions... Use implies complicity. To incorporate AI into the production of art today, no matter how sparingly or subtly, is to endorse Silicon Valley's politics and worldview: its exploitation of both producers and "users," its blithe indifference to the social impact of post-automation layoffs and the environmental assault of industrial data processing, its cramped and uninteresting idea of imagination, its petrification of creation. It's a vote for the assholes...
In short, the essays calls this "recourse to corrective AI" a "filmmaking prosthesis that cheats the viewer and cheapens the performances." And ironically this clashes with the film's depiction of a "principled artist," according to the article. ("Some of the 'retro' digital renderings in the memorial video included in this scene were also, Corbet has admitted, produced with the help of AI.")

The essay notes that several of 2024's other Oscar-nominated films also employed Respeecher, including Dune: Part Two and Emilia Pérez. "What matters here is not this particular infraction but the precedent it sets, the course it establishes for culture."

Slashdot reader databasecowgirl writes: The Times is reporting an interesting study published in Science in which mice demonstrated doing first aid. In the replicated study, an anaesthetised mouse is exposed to another mouse who recognises the distress and clears airway to revive the unconscious mouse.

The mice had never seen an unconscious animal before, so the behaviour is thought to be instinctive.
From the Times: Large social mammals have previously been documented lending assistance to each other. Chimpanzees have been seen tending to wounded companions, dolphins are known to push distressed pod members to the surface to help them breathe, and elephants have been observed assisting their ailing relatives. Never before, however, has such a meticulous, paws-on approach to first aid been recorded in a creature as small as a mouse.

U.S. president Donald Trump called Daylight Saving Time "very costly to our nation" and "inconvenient" in December. Today the Washington Post remembers he'd vowed his Republican party would use their "best efforts" to eliminate it.

But it's still proving to be politically difficult... Polls have shown that most Americans oppose the time shifts but disagree on what should replace them... [U.S. political leaders] also say they are grappling with whether the nation should permanently move the clocks forward one hour, an idea championed by lawmakers on the coasts who say it would allow for more sunshine during the winter, or remain on year-round standard time, which is favored by neurologists who say it aligns with our circadian rhythms. That decision would rest with Congress, not the president. The split often reflects regional, not political, differences, based on where time zones fall; a year-round "spring forward" would mean winter sunrises that could creep past 9 a.m. in cities such as Indianapolis and Detroit, prompting many local lawmakers to oppose the idea...

[A 2022 Senate vote to make Daylight Saving Time permanent] awoke a new lobbying effort from advocates such as the American Academy of Sleep Medicine, which warned that year-round daylight saving time would be unhealthy, citing risks such as higher rates of obesity or metabolic dysfunction. Some researchers warned of a condition dubbed "social jetlag," saying that internal body clocks and rhythms would be persistently misaligned if human clocks were permanently set forward an hour. The concerted resistance from the health groups — which some congressional aides jokingly referred to as "Big Sleep" — helped kill the measure in the House and has contributed to a stalemate over how to proceed...

Today, roughly two-thirds of Americans want to end the clock changes, polls show. But even those Americans don't agree on what should come next. An October 2023 YouGov poll found that 33 percent of respondents wanted year-round daylight saving time, 23 percent wanted permanent standard time, and 9 percent had no preference. The remainder weren't sure or preferred to remain on the current system... The political fight is far from over, with Trump allies such as Sen. Tommy Tuberville (R-Alabama) pledging to keep pushing for year-round daylight saving time. Some congressional Republicans also have privately called for a hearing in front of the House Energy and Commerce Committee, with hopes of advancing the Sunshine Protection Act.

"The early web was fun," Reddit co-founder Alexis Ohanian posted Wednesday on X.com. "It was weird. It was community-driven. It's time to rebuild that.

"Which is why Kevin Rose and I just bought back Digg."

The amount of that purchase is "undisclosed," reports CNBC: The deal is backed by venture capital firms True Ventures, where Rose is a partner, and Ohanian's Seven Seven Six.... The company said in a release that it aims to differentiate itself in the social media market by "focusing on AI innovations designed to enhance the user experience and build a human-centered alternative...." Rose said in a post on X that he and Ohanian "dreamed up features that weren't even possible with yesterday's tech."
"We're bringing more transparency and community partnership," according to Rose's post, "unlike anything you've seen, plus AI that unlocks creativity without sanitizing the human element. The timing is finally right to reimagine what's possible."

"I really disliked you for a long time," Ohanian tells Rose in their joint announcement video. (To which a cheery Rose responds, "Rightfully so.")

But in the video Ohanian also says that today "Our perspective on the world has shifted a lot. You don't want to live in the past, but now we actually have the technology to make better, healthier community experiences." ("Old Rivals, New Vision," says a post on Digg's X.com account, urging readers to "Sign up to get early access when invites go live.")

And Digg.com now just displays this teasing catchphrase. "The front page of the internet, now with superpowers." (At the top of the page there's also a link to watch Diggnation Live at SXSW.)

While valued at $160 million dollars in 2008, Digg's plummeting traffic led to its brand and web site being acquired in 2012 by tech incubator Betaworks for about $500,000, according to CNBC...

Sam Bankman-Fried — one of the largest donors to the Democratic Party — "was convicted of fraud, sentenced to 25 years in prison and mostly went silent," reports the Wall Street Journal. "Until recently..." Now, from behind bars at the Metropolitan Detention Center in Brooklyn, Bankman-Fried is orchestrating an extraordinary public-relations blitz that looks very much like a campaign to make the most audacious trade of his career: support for President Trump's agenda in return for a presidential pardon...

There is little downside to Bankman-Fried's long-shot effort to secure a pardon. As the appeal that he filed last year works its way through the courts, Bankman-Fried, 33, is staring down a prison sentence that could extend until his 50s... The crowning touch of his campaign came on Thursday, when Bankman-Fried gave a jailhouse interview to "The Tucker Carlson Show," which was released on social-media channels including X and YouTube. Appearing on video in a brown jumpsuit, he criticized Washington bureaucrats and crypto regulators — and suggested that he went to prison out of political retribution... [Carlson's title for the interview? "Sam Bankman-Fried on Life in Prison With Diddy, and How Democrats Stole His Money and Betrayed Him."]

The interview hadn't been approved by the Federal Bureau of Prisons, according to a person familiar with the matter. Bankman-Fried spoke with Carlson through a link that is typically used by inmates to communicate with their lawyers, the person said. After the interview, Bankman-Fried was placed in solitary confinement, but he was out by Friday afternoon, according to a person familiar with the matter... Bankman-Fried is trying to highlight in media appearances and in any interaction with Trump's team that FTX customers are set to be made whole with interest through the bankruptcy proceedings — at least in dollar terms. Many of those creditors remain furious that they missed out on bitcoin's rally since November 2022.
Bankman-Fried "wants to set the record straight on his political beliefs, which he believes have been misconstrued," according to the article. "While he has given heavily to Democrats, he has also donated to Republican causes, including the contribution of millions to a group supporting Senator Mitch McConnell."

But the New York Times, citing "people with knowledge" of his pardon-seeking efforts, reported that "So far, the push does not appear to have gained traction."

President Trump has signed an executive order to establish a strategic reserve of cryptocurrencies by using tokens already owned by the government. Reuters reports: A "Strategic Bitcoin Reserve" will be capitalized with bitcoin owned by the federal government that was seized as part of criminal or civil asset forfeiture proceedings, the White House crypto czar, billionaire David Sacks, said in a post on social media platform X. The order kept open the possibility of the government buying bitcoin in future. The U.S. commerce and treasury secretaries "are authorized to develop budget-neutral strategies for acquiring additional bitcoin, provided that those strategies impose no incremental costs on American taxpayers," a factsheet on the White House website said. "This is the most underwhelming and disappointing outcome we could have expected for this week," Charles Edwards, founder of bitcoin-focused hedge fund Capriole Investments, wrote in a post on X. "No active buying means this is just a fancy title for Bitcoin holdings that already existed with the Govt. This is a pig in lipstick."

PhD students trained in small research groups are more likely to remain in academia than those from larger labs, according to a comprehensive analysis published in Nature Human Behaviour.

The study, which examined 1.5 million scientists and 1.8 million mentorships across chemistry, physics and neuroscience, found that trainees from large research groups had 38-48% lower "survival rates" in academia between the 1980s and 1995 compared to their small-group counterparts.

However, researchers from larger labs who do stay in academia tend to achieve greater career success, publishing papers with higher citation rates and more frequently ranking among the most-cited scientists.

The research team, led by social-data scientist Roberta Sinatra from the University of Copenhagen, discovered that successful large-group scientists typically published more first-author papers with their mentors as last authors, suggesting they received substantial attention despite the group size.

An anonymous reader shares a report: A physicist has cast doubt on a test that underlies a high-profile claim by Microsoft to have created the first 'topological qubits', a long-sought goal of the company's quantum computing effort. The critique comes amid mounting speculation about the validity of Microsoft's claim.

Microsoft announced the breakthrough, which could lead to a quantum computer more resistant to information loss than with other approaches, on 19 February. Without a peer-reviewed paper backing up the claim, some researchers were sceptical. An accompanying paper in Nature described a method to measure the read-out from future topological qubits, but did not offer proof of their existence.

In the latest critique, posted as a preprint, Henry Legg, a theoretical physicist at the University of St Andrews, UK, raises concerns about a test that Microsoft uses to look for Majoranas, so-far undiscovered quasiparticles arising from the collective behaviour of electrons that are needed for the topological qubits to work.

Known as the topological gap protocol (TGP), the test is not mentioned in the 19 February Microsoft announcement. But the company has subsequently indicated to Nature's news team, and in a comment online, that it created the topological qubits using the TGP. "Since the TGP is flawed, the very foundations of the qubit are not there," says Legg. Business Insider, separately reports: On February 19, Microsoft unveiled a new quantum processor called Majorana 1. [...] On the same day, Simone Severini, Amazon's head of quantum technologies, emailed CEO Andy Jassy casting doubt on Microsoft's claims, according to a copy of the email obtained by Business Insider.

Severini wrote that Microsoft's underlying scientific paper, released in Nature, "doesn't actually demonstrate" the claimed achievement and only showed that the new chip "could potentially enable future experiments."

[...] Oskar Painter, Amazon's head of quantum hardware, stressed the need to "push back on BS statements like S. Nadella's," likely in reference to the Microsoft CEO Satya Nadella's social media post proclaiming major advancements with the Majorana chip. Further reading:

The U.S. Citizenship and Immigration Services (USCIS) is proposing to expand mandatory social media screening, currently required only for new arrivals, to include all non-citizens already residing in the U.S. who apply for immigration benefits. The Register reports: Back in 2019, the Department of Homeland Security, which runs USCIS, decided anyone looking to enter the US on a work visa or similar had to hand over their social media handles to the authorities so that they could be looked over for wrongdoing and subversion. In fact, this goes back to 2014, at least, to one degree or another, and has been standard procedure for years for foreigners, particularly those coming in on a visa. [...]

On January 20 this year, President Trump signed an executive order calling for much tougher vetting of foreign aliens, and in response, USCIS has proposed rules saying those already in the country who are going through some process with the agency -- such as applying for permanent residency or citizenship -- will have their social media scanned for subversion. That means if you came to America before foreigners' internet presence was screened as it now is, and you're now seeking some kind of immigration benefit, at this rate you'll be subject to the same scanning as those entering the Land of the Free today. The proposed changes have a 60-day comment period for the public to suggest amendments. The last day to send them in is May 5.

Earlier this week, Meta chief product officer Chris Cox said the company's upcoming open-source Llama 4 AI will help power AI agents for hundreds of millions of businesses. CNBC reports: The AI agents won't just be responding to prompts. They will be capable of new levels of reasoning and action -- surfing the web and handling many tasks that might be of use to consumers and businesses. And that's where Shih comes in. Meta's AI is already being used by over 700 million consumers, according to Shih, and her job is to bring the same technologies to businesses. "Not every business, especially small businesses, has the ability to hire these large AI teams, and so now we're building business AIs for these small businesses so that even they can benefit from all of this innovation that's happening," she told CNBC's Julia Boorstin in an interview for the CNBC Changemakers Spotlight series.

She expects the uptake among businesses to happen soon, and spread far and wide. "We're quickly coming to a place where every business, from the very large to the very small, they're going to have a business agent representing it and acting on its behalf, in its voice -- the way that businesses today have websites and email addresses," Shih said. While major companies across sectors of the economy are investing millions of dollars to develop customer LLMs, "doing fancy things like fine tuning models," as Shih put it, "If you're a small business -- you own a coffee shop, you own a jewelry shop online, you're distributing through Instagram -- you don't have the resources to hire a big AI team, and so now our dream is that they won't have to."

For both consumers and businesses, the implications of the advances discussed by Cox and Shih will be significant in daily life. For consumers, Shih says, "Their AI assistant [will] do all kinds of things, from researching products to planning trips, planning social outings with their friends." On the business side, Shih pointed to the 200 million small businesses around the world that are already using Meta services and platforms. "They're using WhatsApp, they're using Facebook, they're using Instagram, both to acquire customers, but also engage and deepen each of those relationships. Very soon, each of those businesses are going to have these AIs that can represent them and help automate redundant tasks, help speak in their voice, help them find more customers and provide almost like a concierge service to every single one of their customers, 24/7."
