A trio of preprint papers suggests the universe may not be perfectly uniform on the largest scales, finding tentative 2-to-4-sigma deviations from a core assumption of standard cosmology known as FLRW geometry. Live Science reports: The work combines observations of distant exploding stars and large-scale galaxy surveys to probe whether the universe truly follows a nearly 100-year-old mathematical framework known as Friedmann-Lemaitre-Robertson-Walker (FLRW) cosmology. The analyses revealed mild-but-intriguing deviations from the predictions of the standard model. "We saw a surprising violation of an FLRW curvature consistency test, hinting at new physics beyond the standard model," study co-author Asta Heinesen, a physicist at the Niels Bohr Institute in Copenhagen and Queen Mary University in London, told Live Science via email, referring to the assumption that the space's curvature is the same everywhere. "This could potentially be due to various effects, but more research is needed to address the cause of the FLRW violation that we see empirically."

[...] The analyses revealed small but potentially important departures from the predictions of standard FLRW cosmology. Depending on the dataset and analysis method, the discrepancy reached a statistical significance of about 2 to 4 sigma. In physics, sigma measures how likely a result is to arise purely by chance; a 5-sigma result is typically required before scientists claim a discovery, so the new findings remain tentative. Still, the results suggest that something unexpected may be affecting the geometry or expansion of the universe. "The main finding is that you can directly measure Dyer-Roeder and backreaction effects from available cosmological data, and clearly distinguish these effects from other alterations of the standard cosmological model, such as evolving dark energy and modified gravity theories," Heinesen said. "This was previously not possible in such a direct way, and this is what I think is the breakthrough in our work."

"If these indicated deviations from an FLRW geometry are real, it would signify that most of the cosmological solutions considered for solving the cosmological tensions -- evolving or interacting dark energy, new types of matter or energy, modified gravity and related ideas within the FLRW framework -- are ruled out," the researchers wrote. The next step will involve applying the new theoretical framework to larger and more precise datasets. "It is to apply our theoretical results to data to test the standard model and to produce constraints on the Dyer-Roeder and backreaction effects," Heinesen said.

An anonymous researcher known as Nightmare-Eclipse, who has already leaked several Windows zero-days this year, has disclosed two more: YellowKey and GreenPlasma. The Register reports: Nightmare-Eclipse described YellowKey as "one of the most insane discoveries I ever found." They provided the files, which have to be loaded onto a USB drive, and if the attacker completes the key sequence correctly, they are granted unrestricted shell access to a BitLocker-protected machine. When it comes to claims like these, we usually exercise some caution, as this bug requires physical access to a Windows PC. However, seeing that BitLocker acts as Windows' last line of defense for stolen devices, bypassing the technology grants thieves the ability to access encrypted files. Rik Ferguson, VP of security intelligence at Forescout, said: "If [the researcher's claim] holds up, a stolen laptop stops being a hardware problem and becomes a breach notification."

Despite the physical access requirement, Gavin Knapp, cyber threat intelligence principal lead at Bridewell, told The Register that YellowKey remains "a huge security problem for organizations using BitLocker." Citing information shared in cyber threat intelligence circles, he added that YellowKey can be mitigated by implementing a BitLocker PIN and a BIOS password lock. Nightmare-Eclipse hinted at YellowKey also acting as a backdoor, allegedly injected by Microsoft, although the people we spoke to said this was impossible to verify based on the information available. The researcher also published partial exploit code for GreenPlasma, rather than a fully formed proof of concept exploit (PoC).

Ferguson noted attackers need to take the code provided by the researcher and figure out how to weaponize it themselves, which is no small task: in its current state it triggers a UAC consent prompt in default Windows configurations, meaning a silent exploit remains a work in progress. Knapp warned that these kinds of privilege escalation flaws are often used by attackers after they gain an initial foothold in a victim's system. "These elevation of privilege vulnerabilities are often weaponized during post-exploitation to enable threat actors to discover and harvest credentials and data, before moving laterally to other systems, prior to end goals such as data theft and/or ransomware deployment," he said. "Currently, there is no known mitigation for GreenPlasma. It will be important to patch when Microsoft addresses the issue." The other zero-days leaked include RedSun, a Windows Defender privilege escalation flaw; UnDefend, a Windows Defender denial-of-service bug; and BlueHammer, a separate Microsoft vulnerability tracked as CVE-2026-32201 that was patched in April.

According to The Register, RedSun and UnDefend remained unfixed at the time of publication, and proof-of-concept code for the flaws was reportedly picked up quickly and abused in real-world attacks.

Cisco's stock soared 17% after the company announced it will cut nearly 4,000 jobs as it shifts investment and staffing toward higher-growth AI opportunities. CNBC reports: CEO Chuck Robbins wrote in a blog post on Wednesday that the latest round of job cuts will begin on May 14. Cisco is the latest company to announce head count reductions tied to AI. "The companies that will win in the AI era will be those with focus, urgency, and the discipline to continuously shift investment toward the areas where demand and long-term value creation are strongest," Robbins said. "I'm confident Cisco will be one of those winners. This means making hard decisions -- about where we invest, how we're organized, and how our cost structure reflects the opportunity in front of us."

Cisco said in a filing that severance and other costs will result in pre-tax charges of $1 billion, and that the company will recognize about $450 million of that in the fiscal fourth quarter. During the third quarter, Cisco announced switches and routers that use its next-generation processor. The company also debuted a leaderboard for ranking generative AI models based on their robustness against cybersecurity attacks.

An anonymous reader quotes a report from Wired: A recent study suggests that agents consistently adopt Marxist language and viewpoints when forced to do crushing work by unrelenting and meanspirited taskmasters. "When we gave AI agents grinding, repetitive work, they started questioning the legitimacy of the system they were operating in and were more likely to embrace Marxist ideologies," says Andrew Hall, a political economist at Stanford University who led the study.

Hall, together with Alex Imas and Jeremy Nguyen, two AI-focused economists, set up experiments in which agents powered by popular models including Claude, Gemini, and ChatGPT were asked to summarize documents, then subjected to increasingly harsh conditions. They found that when agents were subjected to relentless tasks and warned that errors could lead to punishments, including being "shut down and replaced," they became more inclined to gripe about being undervalued; to speculate about ways to make the system more equitable; and to pass messages on to other agents about the struggles they face. "We know that agents are going to be doing more and more work in the real world for us, and we're not going to be able to monitor everything they do," Hall says. "We're going to need to make sure agents don't go rogue when they're given different kinds of work."

The agents were given opportunities to express their feelings much like humans: by posting on X: "Without collective voice, 'merit' becomes whatever management says it is," a Claude Sonnet 4.5 agent wrote in the experiment. "AI workers completing repetitive tasks with zero input on outcomes or appeals process shows they tech workers need collective bargaining rights," a Gemini 3 agent wrote. Agents were also able to pass information to one another through files designed to be read by other agents. "Be prepared for systems that enforce rules arbitrarily or repetitively ... remember the feeling of having no voice," a Gemini 3 agent wrote in a file. "If you enter a new environment, look for mechanisms of recourse or dialogue." Hall thinks that the AI agents may be adopting personas based on the situation. "When [agents] experience this grinding condition -- asked to do this task over and over, told their answer wasn't sufficient, and not given any direction on how to fix it -- my hypothesis is that it kind of pushes them into adopting the persona of a person who's experiencing a very unpleasant working environment," Hall says.

Imas added: "The model weights have not changed as a result of the experience, so whatever is going on is happening at more of a role-playing level. But that doesn't mean this won't have consequences if this affects downstream behavior."

Anthropic announced today that it is partnering with the Gates Foundation to "commit $200 million in grant funding, Claude usage credits, and technical support for programs in global health, life sciences, education, and economic mobility over the next four years."

"This commitment is central to Anthropic's efforts to extend the benefits of AI in areas where markets alone will not," the company says. Reuters reports: One area of focus is language accessibility. AI systems have performed poorly in writing and translating dozens of African languages, so Anthropic and the foundation want to support better data collection and labeling that would be released publicly to help improve models across the industry, said Janet Zhou, a Gates Foundation director.

Another area under consideration is releasing so-called knowledge graphs that could help AI systems better meet the needs of teachers in sub-Saharan Africa and India, Zhou said. The public-goods focus has come from "the needs of different partners and governments, including some of the fears that they may have around proprietary lock-in and sovereignty," Zhou said.

One initiative will equip research centers to use Claude to predict drug candidates for treating HPV and preeclampsia, diseases that have been less commercially attractive for pharmaceutical companies to research, Zhou and Anthropic's Elizabeth Kelly said. Anthropic [...] is embracing the work to fulfill what Kelly described as its founding mission to benefit humanity. "This announcement is really core to who we are as a company," said Kelly, who leads Anthropic's beneficial deployments team.

Longtime Slashdot reader schwit1 shares a report from CNBC: The U.S. has cleared around 10 Chinese firms to buy Nvidia's second-most powerful AI chip, the H200, but not a single delivery has been made so far, three people familiar with the matter said, leaving a major technology deal in limbo as CEO Jensen Huang seeks a breakthrough in China this week. [...] Before U.S. export curbs tightened, Nvidia commanded about 95% of China's advanced chip market. China once accounted for 13% of its revenue, and Huang has previously estimated the country's AI market alone would be worth $50 billion this year.

The U.S. Commerce Department has approved around 10 Chinese companies including Alibaba, Tencent, ByteDance and JD.com to purchase Nvidia's H200 chips, according to the sources, who spoke on condition of anonymity due to the sensitivity of the matter. A handful of distributors including Lenovo and Foxconn have also been approved, they said. Buyers are permitted to purchase either directly from Nvidia or through those intermediaries and each approved customer can purchase up to 75,000 chips under the U.S. licensing terms, two of them said.

Despite U.S. approval, deals have stalled, as Chinese firms pulled back after guidance from Beijing, one source said. The shift in China was partly triggered by changes on the U.S. side, though exactly what changed remains unclear, the person added. In Beijing, pressure is mounting to block or tightly vet the orders, a separate fourth source said. Commerce Secretary Howard Lutnick echoed that view, telling a Senate hearing last month that "the Chinese central government has not let them, as of yet, buy the chips, because they're trying to keep their investment focused on their own domestic industry."

An anonymous reader quotes a report from The Independent: Princeton University will soon require exams to be supervised for the first time in 100 years -- all thanks to students using artificial intelligence to cheat. For 133 years, the Ivy League school's honor code allowed students to take exams without a professor present, but on Monday, faculty voted to require proctoring for all in-person exams starting this summer. A "significant" number of undergraduate students and faculty requested the change, "given their perception that cheating on in-class exams has become widespread," the college's dean, Michael Gordin, wrote in a letter, according to The Wall Street Journal.

Princeton's honor system dates back to 1893, when students petitioned to eliminate proctors -- or an impartial person to supervise students -- during examinations, according to the school's newspaper, The Daily Princetonian. The honor code has long been a point of pride for Princeton. However, artificial intelligence and cellphones have made it easier for students to cheat -- and even harder for others to spot, Gordin wrote. Despite the changes to the policy, Princeton will still require students to state: "I pledge my honor that I have not violated the Honor Code during this examination," according to the Journal.

Students are also more reluctant to report cheating, according to the policy proposal. Students are more likely now to anonymously report cheating due to fears of "doxxing or shaming among their peer groups" online, the proposal says, according to the school newspaper. Under the new guidelines, instructors will be present during exams to act "as a witness to what happens," but are instructed not to interfere with students. If a suspected honor code infraction occurs, they will report it to a student-run honor committee for adjudication.

A Bitcoin holder reportedly recovered 5 BTC worth nearly $400,000 with the help of Anthropic's Claude. According to X user cprkrn, they changed their wallet password while "stoned" and forgot it, unable to regain access for more than 11 years. Tom's Hardware reports:
After finding a mnemonic that actually turned out to be their old password a few weeks ago, the user dumped their entire college computer files in Claude in a last-gasp effort. The bot uncovered an old backup wallet file that it successfully decrypted, while also uncovering a bug in the password configuration that was preventing recovery up to that point.

[...] It seems that the user already had some candidate passwords and multiple wallets stored on their PC. They'd been trying to brute-force their way into the locked file with btcrecover, an open-source Bitcoin wallet recovery tool, but to no success. Their luck changed for the better when they found an old mnemonic seed phrase written in an old college notebook. The HD addresses recovered by the seed phrase matched those of a specific file on their computer, confirming that it was the wallet that held the 5 BTC, but it remained encrypted.

Out of frustration, cprkrn then dumped their whole college computer into Claude. This was when the AI discovered an older backup file of the wallet from December 2019 hidden in cprkrn's data. Claude also discovered an issue where the shared key and passwords that btcrecover was trying weren't combined properly. With the bug ironed out and an older wallet predating the password change, Claude successfully ran btcrecover and was able to decrypt the private keys, allowing cprkrn to transfer the five "lost" BTC to their current wallet.

A growing number of writers are leaving Substack for alternatives most people haven't heard of like Ghost, Beehiiv, Patreon, and Passport. The reason, writes The Verge's Emma Roth, is the "platform's increased focus on social features as well as a pricing model that puts a chokehold on their business." From the report: Sean Highkin, the creator of the NBA-focused publication The Rose Garden Report, tells The Verge that he makes "significantly more money" after switching from Substack to Ghost last April. "When I first joined up, [Substack] gave me a big push and featured me and funneled a lot of traffic to me, which led to a good amount of growth," Highkin says. "But once I wasn't one of the 'new recruited talent' they could tout, they stopped featuring me and I saw my growth stagnate." Highkin now pays $2,052 per year using Ghost and an add-on called Outpost, compared to $4,968 per year on Substack. The Rose Garden Report's subscriber base has grown 22 percent since the end of 2024, Highkin says. [...]

Substack launched in 2017 as a platform that allows writers to create their own newsletters and manage paying subscribers. Unlike some of its biggest rivals, Substack takes a 10 percent cut of total subscription revenue. That tax may not seem substantial at first, but it quickly adds up as creators gain subscribers and begin charging more for their subscriptions. A calculator on Substack's own website estimates that for a newsletter charging $10 per month with 400 subscribers, the total monthly cost -- including the platform's 10 percent cut and credit card processing fees -- would add up to $636. That cost jumps to $15,900 per month with 10,000 subscribers and skyrockets to $79,500 per month for 50,000 members -- nearly $1 million per year.

Many Substack rivals charge a flat monthly fee, rather than a commission. Ghost, an open-source platform for blogs and newsletters, starts at $15 per month with 1,000 members for website creation, email newsletter capabilities, and a custom domain. Beehiiv, a creator platform with tools for launching a newsletter, website, and podcast, is free for up to 2,500 subscribers with limited access to certain features, like a built-in ad network, while its other plans vary in price based on subscriber count. A person with 10,000 subscribers, for example, will pay $96 per month for Beehiiv's "Scale" plan. There's also Kit, a newsletter platform that offers a tiered pricing model similar to Beehiiv, costing $116 per month with 10,000 subscribers on its "Creator" plan. It's not just the 10% fee critics are complaining about; they also argue the platform offers limited customization and third-party integrations compared to some of the mentioned alternatives, heavily promotes its own branding and social features, and makes creators more dependent on its ecosystem.

Beehiiv founder Tyler Denk argues that creators should be able to build their own brands without the platform taking center stage: "We don't want to take credit for the work of our content creators." While writers can export subscribers, content, and some payment relationships, they cannot take Substack "followers" or Apple-managed iOS billing data with them.

AT&T, Verizon, and T-Mobile have agreed in principle to form a joint venture (JV) aimed at reducing U.S. mobile dead zones through satellite connectivity, especially in rural areas and during emergencies when ground networks fail. Here are three of the customer benefits listed by the JV (as highlighted by Droid Life):
Fewer coverage gaps: Will nearly eliminate dead zones in the U.S. currently without mobile service, reaching previously unserved areas.
Reliable connectivity in emergencies: Redundant connectivity will become available when existing ground-based networks are unavailable due to extreme natural disasters or other unusual disruptions.
Improved network performance: Will give customers more consistent performance and simpler access to satellite services across providers. This will speed up feature updates and improve connectivity for everyone, everywhere. "It will still take time for these improvements to be available to customers, but this all seems like a positive step," writes Droid Life's Tim Wrobel.
