About one sixth of global cropland is contaminated by toxic heavy metals, researchers have estimated, with as many as 1.4 billion people living in high-risk areas worldwide. From a report: Approximately 14 to 17% of cropland globally -- roughly 242m hectares -- is contaminated by at least one toxic metal such as arsenic, cadmium, cobalt, chromium, copper, nickel or lead, at levels that exceed agricultural and human health safety thresholds. The analysis, which was conducted by the American Association for the Advancement of Science (AAAS) and published in the journal Science, collected data from more than 1,000 regional studies across the globe, as well as using machine learning technology. Dr Liz Rylott, a senior lecturer in the department of biology at the University of York, who was not involved in the research, said: "These findings reveal the deeply worrying extent to which these natural poisons are polluting our soils, entering our food and water, and affecting our health and our environment. Often collectively called heavy metals, these elements cause a range of devastating health problems, including skin lesions, reduced nerve and organ functions, and cancers." Toxic metal pollution in soil originates from both natural and human activity. Contaminated soil causes significant risks to ecosystems and human health as well as reducing crop yields, jeopardising water quality and food safety owing to bioaccumulation in farm animals. Toxic metal contamination can persist for decades once pollution has been introduced into soil.

OpenAI's latest reasoning models, o3 and o4-mini, hallucinate more frequently than the company's previous AI systems, according to both internal testing and third-party research. On OpenAI's PersonQA benchmark, o3 hallucinated 33% of the time -- double the rate of older models o1 (16%) and o3-mini (14.8%). The o4-mini performed even worse, hallucinating 48% of the time. Nonprofit AI lab Transluce discovered o3 fabricating processes it claimed to use, including running code on a 2021 MacBook Pro "outside of ChatGPT." Stanford adjunct professor Kian Katanforoosh noted his team found o3 frequently generates broken website links. OpenAI says in its technical report that "more research is needed" to understand why hallucinations worsen as reasoning models scale up.

Netflix Co-CEO Ted Sarandos pushed back on director James Cameron's recent assertion that AI could slash film production costs by half, arguing instead for quality improvements over cost reduction during Netflix's first-quarter earnings call Thursday. "I read the article too about what Jim Cameron said about making movies 50% cheaper," Sarandos said. "I remain convinced that there's an even bigger opportunity to make movies 10% better." Sarandos pointed to Netflix's current AI implementations in set references, pre-visualization, VFX sequence preparation, and shot planning. He said AI-powered tools have democratized high-end visual effects that were once exclusive to big-budget productions. The executive cited 2019's "The Irishman" as a benchmark, noting its "very cutting-edge, very expensive de-aging technology that still had massive limitations." In contrast, he referenced cinematographer Rodrigo Prieto's directorial debut "Pedro Paramo," which employed AI-powered de-aging at "a fraction" of The Irishman's cost. "The entire budget of the film was about what the VFX cost on The Irishman," Sarandos explained. "Same creator using new tools, better tools, to do what was impossible five years ago."

A new Seagate report reveals that hard drives significantly outperform solid-state drives in environmental sustainability metrics, particularly when accounting for manufacturing processes. According to the storage-maker's ""Decarbonizing Data">Decarbonizing Data" [PDF] study, the embodied carbon from manufacturing a 30TB SSD reaches 4,915 kg of CO2 -- approximately 160 times higher than the 29.7 kg produced in creating a comparable hard drive. The analysis measures the full manufacturing footprint, including "upstream extraction, production, transport, bill of material, manufacturing, packaging, and distribution stages" of each technology's lifecycle. When calculated per terabyte annually, the difference remains stark: less than 0.2 kg CO2/TB/year for hard drives versus 32 kg for SSDs. Operational efficiency follows similar patterns, with hard drives consuming 9.6 watts during use versus 20 watts for SSDs, translating to 0.32 and 0.5 watts per terabyte respectively.

Bruce66423 shares a report: Toothpaste can be widely contaminated with lead and other dangerous heavy metals, new research shows. Most of 51 brands of toothpaste tested for lead contained the dangerous heavy metal, including those for children or those marketed as green. The testing, conducted by Lead Safe Mama, also found concerning levels of highly toxic arsenic, mercury and cadmium in many brands. About 90% of toothpastes contained lead, 65% contained arsenic, just under half contained mercury, and one-third had cadmium. Many brands contain a number of the toxins. The highest levels detected violated the state of Washington's limits, but not federal limits. The thresholds have been roundly criticized by public health advocates for not being protective -- no level of exposure to lead is safe, the federal government has found. Bruce66423 asks: "As ever the question that should be asked is: 'What level is worth worrying about and why?'"

An anonymous reader shares a report: Members of the European Parliament were offered special pouches to protect digital devices from espionage and tampering for a visit to Hungary this week, a sign of rising spying fears within Europe. Five lawmakers from the Parliament's civil liberties committee traveled to Hungary on Monday for a three-day visit to inspect the EU member country's progress on democracy, the rule of law and fundamental rights. One lawmaker on the trip confirmed to POLITICO that the Parliament officials joining the delegation were offered Faraday bags -- special metal-lined pouches that block electromagnetic signals -- by the Parliament's services and were also advised to be cautious about using public Wi-Fi networks or charging facilities.

A communication error between GoDaddy Registry and Markmonitor took Zoom's services offline for almost two hours on Wednesday when GoDaddy mistakenly blocked the zoom.us domain. The outage affected all services dependent on the zoom.us domain. GoDaddy's block prevented top-level domain nameservers from maintaining proper DNS records for zoom.us. This created a classic domain resolution failure -- when users attempted to connect to any zoom.us address, their requests couldn't be routed to Zoom's servers because the domain effectively disappeared from the internet's addressing system. Video meetings abruptly terminated mid-session with browser errors indicating the domain couldn't be found. Zoom's status page (status.zoom.us) went offline, hampering communication efforts. Even Zoom's main website at zoom.com failed as the content delivery network couldn't reach backend services hosted on zoom.us servers. Customer support capabilities collapsed when account managers using Zoom's VoIP phones lost connectivity. Resolution required coordinated effort between Zoom, Markmonitor, and GoDaddy to identify and remove the block. After service restoration, users needed to manually flush their DNS caches using command line instructions (including the sudo dscacheutil -flushcache; sudo killall -HUP mDNSResponder command for Mac users).

Rice, the world's most consumed grain, will become increasingly toxic as the atmosphere heats and as carbon dioxide emissions rise, potentially putting billions of people at risk of cancers and other diseases, according to new research published this week in The Lancet. From a report: Eaten every day by billions of people and grown across the globe, rice is arguably the planet's most important staple crop, with half the world's population relying on it for the majority of its food needs, especially in developing countries. But the way rice is grown -- mostly submerged in paddies -- and its highly porous texture mean it can absorb unusually high levels of arsenic, a potent carcinogenic toxin that is especially dangerous for babies. After growing rice in controlled fields for six years, researchers from Columbia University and international partners found that when both temperature and CO2 increased in line with climate projections, arsenic levels in rice grains rose significantly. "When we put both of them together, then wow, that was really something we were not expecting," said Lewis Ziska, a plant physiologist at Columbia University who led the study. "You're looking at a crop staple that's consumed by a billion people every day, and any effect on toxicity is going to have a pretty damn large effect." Inorganic arsenic exposure has been linked to cancers, heart disease, and neurological problems in infants. Disease risk rose across all seven top rice-consuming Asian countries analyzed. "This is one more reason to intervene -- to control people's exposure," said co-author Keeve Nachman of Johns Hopkins University. "The No. 1 thing we can do is everything in our power to slow climate change."

Nature has published an analysis of the 21st century's most-cited scientific papers, revealing a surprising pattern: breakthrough discoveries like mRNA vaccines, CRISPR, and gravitational waves don't make the list. Instead, a 2016 Microsoft paper on "deep residual learning" networks claims the top spot, with citations ranging from 103,756 to 254,074 depending on the database. The list overwhelmingly features methodology papers and software tools rather than groundbreaking discoveries. AI research dominates with four papers in the top ten, including Google's 2017 "Attention is all you need" paper that underpins modern language models. The second-most-cited paper -- a 2001 guide for analyzing gene expression data -- was explicitly created to be cited after journal reviewers rejected references to a technical manual. As sociologist Misha Teplitskiy noted, "Scientists say they value methods, theory and empirical discoveries, but in practice the methods get cited more."

New research suggests Oda Ujiharu, long derided as feudal Japan's most ineffective military leader, may have been mischaracterized. The Sengoku-period daimyo, who ruled from Oda Castle in present-day Ibaraki Prefecture, lost his fortress an unprecedented nine times to rival clans -- but recaptured it eight times, often with inferior forces. "His refusal to accept defeat and his iron will to get up and keep fighting is why many historians reject the 'weakest samurai warlord' nickname and instead refer to him as 'The Phoenix,'" notes the research published in Tokyo Weekender. While Ujiharu's battlefield decisions appear strategically baffling -- repeatedly abandoning castle defenses for open combat -- some researchers propose these actions were deliberately taken to protect peasant settlements from the devastation of prolonged sieges. From the article: Ujiharu's blind charges may actually have had a noble purpose. Japanese battles involving castles almost always turned into sieges, and those always ended the same way: with the nearby fields and peasant settlements being either destroyed to try and draw the lord out of the castle or looted to feed the occupying army. Some researchers believe that Ujiharu was trying to avoid a siege to save his subjects. Despite numerous military setbacks, Ujiharu maintained remarkable loyalty from his subordinates. Historical records indicate that after his initial campaigns, attempts to bribe or threaten his retainers to defect consistently failed. The daimyo demonstrated considerable diplomatic acumen, forming multiple alliances with former enemies throughout his career. His downfall came only after hesitating to pledge allegiance to Toyotomi Hideyoshi during Japan's unification, resulting in his lands being confiscated.

A ground-breaking project to suck carbon out of the sea has started operating on England's south coast. From a report: The small pilot scheme, known as SeaCURE, is funded by the UK government as part of its search for technologies that fight climate change. [...] These projects, known as carbon capture, usually focus either on capturing emissions at source or pulling them from the air. What makes SeaCure interesting is that it is testing whether it might be more efficient to pull planet-warming carbon from the sea, since it is present in greater concentrations in water than in the air.

Sage has retracted 678 more papers from the Journal of Intelligent and Fuzzy Systems (JIFS), concluding an investigation that has now purged 1,561 articles -- the most ever removed from a single journal. The publisher, which acquired JIFS from IOS Press in November 2023, began investigating the journal in early 2024 after discovering "indicators that raised concerns about the authenticity of the research and the peer review process." This final batch follows 467 articles retracted in August and another 416 in January. Problems in the retracted papers included citation manipulation, "tortured phrases," unauthorized third-party involvement in submissions, and evidence suggesting collusion between authors and reviewers. Most authors were from India and China, with some from Pakistan, Turkey, Iran, and Iraq. Cengiz Kahraman of Istanbul Technical University, who authored 20 of the retracted papers, disputed the decision, telling Retraction Watch that Sage acted "without any reason and evidence." The journal has now resumed publishing.

An AI support bot for the code editor Cursor invented a nonexistent subscription policy, triggering user cancellations and public backlash this week. When developer "BrokenToasterOven" complained about being logged out when switching between devices, the company's AI agent "Sam" falsely claimed this was intentional: "Cursor is designed to work with one device per subscription as a core security feature." Users took the fabricated policy as official, with several announcing subscription cancellations on Reddit. "I literally just cancelled my sub," wrote the original poster, adding that their workplace was "purging it completely." Cursor representatives scrambled to correct the misinformation: "Hey! We have no such policy. You're of course free to use Cursor on multiple machines." Cofounder Michael Truell later apologized, explaining that a backend security change had unintentionally created login problems.

Amazon plans to release its first TV streaming device powered by Vega OS later this year while courting major publishers to bring their apps to the platform, according to Lowpass, which cites sources familiar with the company's plans and multiple leaks. Vega, a Linux-based operating system, may eventually replace Amazon's Android-based Fire OS across its device ecosystem. The company has already implemented Vega in three products: the Echo Show 5 and Echo Hub smart displays, as well as the Echo Spot smart clock/speaker. The tech giant has moved more cautiously in transitioning its TV hardware to Vega, having previously delayed a Vega-powered streaming stick originally slated for release in late 2024.

Synology's upcoming Plus Series NAS systems will restrict full functionality to users who install the company's self-branded hard drives, Tom's Hardware is reporting, marking a significant shift in the consumer NAS market. While third-party drives will still work for basic storage, critical features including drive health monitoring, volume-wide deduplication, lifespan analysis, and automatic firmware updates will be disabled, the publication said. The restriction doesn't apply to Synology's 2024 and older models, only affecting new Plus Series devices targeted at SMBs and advanced home users. Synology itself doesn't manufacture drives but rebrands HDDs from major manufacturers like Seagate, Western Digital, and Toshiba, often with custom firmware that functions as DRM. According to Synology, the change follows successful implementation in their enterprise solutions and will deliver "higher performance, increased reliability, and more efficient support." A workaround exists: users can initialize a non-Synology drive in an older Synology NAS and then migrate it to a new Plus model without restrictions.

During Meta's antitrust trial this week, lawyers representing Apple, Google, and Snap each expressed irritation with Meta over the slides it presented on Monday that The Verge found to contain easy-to-remove redactions. From a report: Attorneys for both Apple and Snap called the errors "egregious," with Apple's representative indicating that it may not be able to trust Meta with its internal information in the future. Google's attorney also blamed Meta for jeopardizing the search giant's data with the mistake. Details about the attorneys' comments come from The Verge's Lauren Feiner, who is currently in the courtroom where proceedings are taking place today. Apple, Google, and Meta did not immediately respond to The Verge's request for comment. Snap declined to comment. Snap's attorney maligned Meta's "cavalier approach and casual disregard" of other companies swept into the case, and wondered if "Meta would have applied meaningful redactions if it were its own information that was at stake."

Fraud rings using fake "bot" students have infiltrated America's community colleges, stealing over $11 million from California's system alone in 2024. The nationwide scheme, which began in 2021, targets open-admission institutions where scammers enroll fictitious students in online courses to collect financial aid disbursements. "We didn't used to have to decide if our students were human," said Eric Maag, who has taught at Southwestern College for 21 years. Faculty now spend hours vetting suspicious enrollees and analyzing AI-generated assignments. At Southwestern in Chula Vista, professor Elizabeth Smith discovered 89 of her 104 enrolled students were fraudulent. The California Community College system estimates 25% of all applicants statewide are bots. Community college administrators describe fighting an evolving technological battle against increasingly sophisticated fraud tactics. The fraud crisis has particularly impacted asynchronous online courses, crowding real students out of classes and fundamentally altering faculty roles.

Meta has disabled Apple Intelligence features across its iOS applications, including Facebook, WhatsApp, and Threads, according to Brazilian tech blog Sorcererhat Tech. The block affects Writing Tools, which enable text creation and editing via Apple's AI, as well as Genmoji generation. Users cannot access these features via the standard text field interface in Meta apps. Instagram Stories have also lost previously available keyboard stickers and Memoji functionality. While Meta hasn't explained the decision, it likely aims to drive users toward Meta AI, its own artificial intelligence service that offers similar text and image generation capabilities. The move follows failed negotiations between Apple and Meta regarding Llama integration into Apple Intelligence, which reportedly collapsed over privacy disagreements. The companies also maintain ongoing disputes regarding App Store policies.

A global gambling syndicate led by secretive Tasmanian gambler Zeljko Ranogajec and London bookmaker Bernard Marantelli successfully executed an unprecedented operation to claim a $57.8 million Texas lottery jackpot in 2023. The group, operating through a limited partnership called Rook TX, purchased 99.3% of all possible number combinations, printing over 25 million tickets across four makeshift workshops in Texas. Using dozens of official lottery terminals and working nearly around the clock for three days, the team systematically printed hundreds of tickets per second. Texas officials have since launched investigations, with Lt. Governor Dan Patrick calling it "the biggest theft from the people of Texas in the history of Texas." The Texas Rangers are now investigating the operation. Through legal representation, the syndicate maintains they "followed all applicable laws, rules and regulations" throughout the process.
