MIT said Friday it can no longer stand behind a widely circulated paper on AI written by a doctoral student in its economics program. The paper said that the introduction of an AI tool in a materials-science lab led to gains in new discoveries, but had more ambiguous effects on the scientists who used it. WSJ: MIT didn't name the student in its statement Friday, but it did name the paper. That paper, by Aidan Toner-Rodgers, was covered by The Wall Street Journal and other media outlets. In a press release, MIT said it "has no confidence in the provenance, reliability or validity of the data and has no confidence in the veracity of the research contained in the paper." The university said the author of the paper is no longer at MIT. The paper said that after an AI tool was implemented at a large materials-science lab, researchers discovered significantly more materials -- a result that suggested that, in certain settings, AI could substantially improve worker productivity. But it also showed that most of the productivity gains went to scientists who were already highly effective, and that overall the AI tool made scientists less happy about their work.

Montana has enacted SB 282, becoming the first state to prohibit law enforcement from purchasing personal data they would otherwise need a warrant to obtain. The landmark legislation closes what privacy advocates call the "data broker loophole," which previously allowed police to buy geolocation data, electronic communications, and other sensitive information from third-party vendors without judicial oversight. The new law specifically restricts government access to precise geolocation data, communications content, electronic funds transfers, and "sensitive data" including health status, religious affiliation, and biometric information. Police can still access this information through traditional means: warrants, investigative subpoenas, or device owner consent.

The Federal Trade Commission has postponed enforcement of its consumer-friendly "click to cancel" rule from May 14 to July 14, giving businesses two additional months to comply. The regulation requires companies to make subscription cancellations as straightforward as the sign-up process, prohibiting practices like forcing customers who subscribed online to navigate through chatbots or call centers to cancel. The rule, established under former Democratic Chair Lina Khan, unsurprisingly has garnered support from consumer advocates while facing legal opposition from industry groups. A coalition including the U.S. Chamber of Commerce and organizations representing major telecom and media companies -- Charter Communications, Comcast, Disney Entertainment, and Warner Bros. Discovery -- has sued to block implementation, claiming the agency exceeded its authority.

The Department of Commerce officially rescinded the Biden administration's Artificial Intelligence Diffusion Rule on Tuesday, just days before its May 15 implementation date. The rule would have imposed first-ever export restrictions on U.S.-made AI chips to dozens of countries while tightening existing controls on China and Russia. Instead of implementing blanket restrictions, the DOC signaled a shift toward direct country-by-country negotiations. The department released interim guidance reminding companies that using Huawei's Ascend AI chips anywhere violates U.S. export rules and warned about consequences of allowing U.S. chips to train AI models in China. Commerce Secretary for Industry and Security Jeffery Kessler criticized the previous administration's approach, calling it "ill-conceived and counterproductive."

Longtime Slashdot reader schwit1 shares a report from Earth.com: McDermitt Caldera in Oregon is attracting attention for what could be one of the largest lithium deposits ever identified in the United States. Many view it as a potential boost for domestic battery production, while local communities voice concern over the impact on wildlife and cultural sites. The excitement stems from estimates that value the deposit at about $1.5 trillion. Some geologists say these ancient volcanic sediments could contain between 20 and 40 million metric tons of lithium. The study is published in the journal Minerals.

Mexico has filed a lawsuit against Google for changing the name of the Gulf of Mexico to "Gulf of America" for U.S. users on Google Maps, following a Republican-led House vote on Thursday to codify the name change. President Claudia Sheinbaum argues the U.S. only has authority to rename its portion of the continental shelf and warned of legal action unless Google reversed the change. The Guardian reports: "All we want is for the decree issued by the US government to be complied with," Sheinbaum said. "The US government only calls the portion of the US continental shelf the Gulf of America, not the entire gulf, because it wouldn't have the authority to name the entire gulf," she added. In response to Trump, Sheinbaum has cheekily suggested calling the United States "America Mexicana" -- Mexican America, pointing to a map dating back to before 1848, when one-third of her country was seized by the United States.

A U.S. senator introduced a bill on Friday that would direct the Commerce Department to require location verification mechanisms for export-controlled AI chips, in an effort to curb China's access to advanced semiconductor technology. From a report: Called the "Chip Security Act," the bill calls for AI chips under export regulations, and products containing those chips, to be fitted with location-tracking systems to help detect diversion, smuggling or other unauthorized use of the product. "With these enhanced security measures, we can continue to expand access to U.S. technology without compromising our national security," Republican Senator Tom Cotton of Arkansas said. The bill also calls for companies exporting the AI chips to report to the Bureau of Industry and Security if their products have been diverted away from their intended location or subject to tampering attempts.

An anonymous reader shares a report: Major tech companies lobbying to salvage a tax deduction for research and development are warning they may pull back from high-profile pledges of new US investments if Congress doesn't fully reinstate the break. Big tech companies have pledged more than $1.6 trillion in investments in the US since Donald Trump took office, promising to build factories and data centers in alignment with Trump's push to build in America. But industry representatives are signaling those promises will be imperiled if Congress doesn't fully reinstate the R&D tax deduction, which was pared back to help offset the massive cost of President Donald Trump's 2017 bill. At the time, it was estimated that limiting the provision would temporarily raise about $120 billion from 2018 to 2027. "A lot of those announcements are predicated on an expectation the administration and Congress will partner together on reinstating those R&D provisions," said Jason Oxman, president of the Information Technology Industry Council, a trade group that includes among its members Amazon, Apple, Anthropic, Alphabet, and IBM. Lobbyists representing tech companies that announced US investments have made similar claims to congressional aides and lawmakers, according to people familiar with the conversations.

President Trump on Thursday attacked a law signed by President Joe Biden aimed at expanding high-speed internet access, calling the effort "racist" and "totally unconstitutional" and threatening to end it "immediately." The New York TimesL: Mr. Trump's statement was one of the starkest examples yet of his slash-and-burn approach to dismantling the legacy of his immediate predecessor in this term in office. The Digital Equity Act, a little-known effort to improve high-speed internet access in communities with poor access, was tucked into the $1 trillion bipartisan infrastructure bill that Mr. Biden signed into law early in his presidency. The act was written to help many different groups, including veterans, older people and disabled and rural communities. But Mr. Trump, using the incendiary language that has been a trademark of his political career, denounced the law on Thursday for also seeking to improve internet access for ethnic and racial minorities, raging in a social media post that it amounted to providing "woke handouts based on race."

The Drug Enforcement Administration has quietly ended its body camera program barely four years after it began, ProPublica reports, citing an internal email. From the report: On April 2, DEA headquarters emailed employees announcing that the program had been terminated effective the day before. The DEA has not publicly announced the policy change, but by early April, links to pages about body camera policies on the DEA's website were broken. The email said the agency made the change to be "consistent" with a Trump executive order rescinding the 2022 requirement that all federal law enforcement agents use body cameras. But at least two other federal law enforcement agencies within the Justice Department -- the U.S. Marshals Service and the Bureau of Alcohol, Tobacco, Firearms and Explosives -- are still requiring body cameras, according to their spokespeople.

Most people in the United States rely on federal science in their daily lives but don't realize it, a new nationwide poll of U.S. adults shows. NPR: The poll was conducted in early April by the Association of Science and Technology Centers, the association for science museums and other educational science centers in the U.S. The poll found that on a weekly basis more than 90% of people use weather forecasts, job market reports, food safety warnings and other information that is based on federal science. But only 10% of respondents are concerned that cuts to federal support for science might impact their access to such information. The Trump administration has made deep budget and personnel cuts to federal agencies that collect weather data and do safety inspections at factories that make food and prescription drugs, among many science-related functions. The association conducted the poll to understand current attitudes about science in the U.S. and inform how their member institutions, which include science museums, aquariums and zoos, can better serve the public.

America's federal government "is a veritable cosmos of information, made up of constellations of databases," warns the Atlantic. The FBI "has a facial-recognition apparatus capable of matching people against more than 640 million photos — a database made up of driver's license and passport photos, as well as mug shots. The Homeland Security department holds data "about the movements of every person who travels by air commercially". America's Drug Enforcement Administration "tracks license plates scanned on American roads." And there's also every taxpayer's finance and employment history..." Government agencies including the IRS, the FBI, DHS, and the Department of Defense have all purchased cellphone-location data, and possibly collected them too, via secretive groups such as the National Geospatial-Intelligence Agency. That means the government has at least some ability to map or re-create the past everyday movements of some American citizens. But now the information at individual agencies "is being pooled together. The question is Why? And what does the administration intend to do with it?" A White House spokesperson confirmed to the Atlantic that data collected by different agencies is now being combined. (They said that "Through data sharing between agencies, departments are collaborating to identify fraud and prevent criminals from exploiting hardworking American taxpayers.") But a March executive explicitly stated an aim "to eliminate the data silos that keep everything separate." The article accuses the administration officials of "not just undoing decades of privacy measures. They appear to be ignoring that they were ever written." The Atlantic spoke with former government officials "who have spent time in these systems," reporting that "to a person, these experts are alarmed about the possibilities for harm, graft, and abuse... Collecting and then assembling data in the industrial way — just to have them in case they might be useful — would represent a huge and disturbing shift for the government..." "A fragile combination of decades-old laws, norms, and jungly bureaucracy has so far prevented repositories such as these from assembling into a centralized American surveillance state. But that appears to be changing... DOGE has systematically gained access to sensitive data across the federal government "in ways that people in several agencies have described to us as both dangerous and disturbing."

Remember when U.S. National Security Adviser Mike Waltz mistakenly included a journalist in an encrypted chatroom to discuss looming U.S. military action against Yemen's Houthis? A recent photo of a high-level cabinet meeting caught Waltz using a "less-secure Signal app knockoff," reports the Guardian: The chat app Waltz was using appears to be a modified version of Signal called TM SGNL, made by a company that copies messaging apps but adds an ability to retain messages and archive them. The White House officials may be using the modified Signal in order to comply with the legal requirement that presidential records be preserved... That function suggests the end-to-end encryption that makes Signal trusted for sharing private communications is possibly "not maintained, because the messages can be later retrieved after being stored somewhere else", according to 404 Media. Thursday the national security adviser was removed from his position, the article points out. He was instead named America's ambassador to the United Nations.

An anonymous reader quotes a report from the BBC: Temu has said it will stop selling goods imported from China in the US directly to customers from its platform. The online marketplace said sales would now be handled by "locally based sellers," with orders fulfilled from within the country. The move comes as a duty-free rule for low-value packages is closed. Temu, and rival Chinese retail giant Shein, had previously relied on the so-called "de minimis" exemption to sell and ship low-value items directly to the US without having to pay duties or import taxes. Temu said it had been actively recruiting US firms to join the platform. "All sales in the US are now handled by locally based sellers, with orders fulfilled from within the country. "The move is designed to help local merchants reach more customers and grow their businesses," it added. Supporters of the de minimis loophole, which applied to parcels worth less than $800, argue it helped streamline the customs process. But both Trump and his predecessor, Joe Biden, said it damaged American businesses and was used to smuggle illegal goods, including drugs. In February, Trump briefly closed the loophole but the suspension was quickly paused as delivery services and customs agencies struggled to adjust. During the pause, the U.S. Postal Service even stopped accepting parcels from mainland China and Hong Kong.

The FDA has approved gene-edited pigs for human consumption, potentially marking the first major commercial application of CRISPR technology in the food chain. Created by British company Genus, these pigs have had their DNA modified to remove the receptor that the porcine reproductive and respiratory syndrome (PRRS) virus uses to enter cells, rendering them immune to 99% of known virus variants. PRRS causes losses of approximately $300 million annually in the US alone by killing piglets and spreading rapidly through factory farms. According to Matt Culbertson, chief operating officer of Genus subsidiary Pig Improvement Company, the gene-edited pork could reach US markets sometime next year. Before launching sales to pig farms, Genus must secure regulatory approval in key export markets including Mexico, Canada, Japan, and China.

Nature: A forthcoming policy from the US National Institutes of Health (NIH) will target - and at least temporarily stop -- funding to laboratories and hospitals outside the United States, threatening thousands of global-health projects and international collaborations on topics such as emerging infectious diseases and cancer. The NIH, the world's largest funder of biomedical research, plans to release the policy in the next week. Some agency staff members have already been instructed to hold funds for foreign institutions that are part of both new research grants and grants coming up for renewal, according to multiple agency employees who spoke to Nature under the condition of anonymity because they are not authorized to speak to the press.

"Only the United States, China and Germany have larger economies than California," reports CNN. In fact, they add that California "outpaced all three countries with growth of 6% last year," according to the California governor's office (which cites new data from the International Monetary Fund and the U.S. Bureau of Economic Analysis): In 2024, California's growth rate of 6% outpaced the top three economies: U.S. (5.3%), China (2.6%) and Germany (2.9%)... With an increasing state population and recent record-high tourism spending, California is the nation's top state for new business starts, access to venture capital funding, and manufacturing, high-tech, and agriculture. The state drives national economic growth and also sends over $83 billion more to the federal government than it receives in federal funding. California is the leading agricultural producer in the country and is also the center for manufacturing output in the United States, with over 36,000 manufacturing firms employing over 1.1 million Californians. The data shows that last year California accounted for 14% of America's GDP, CNN points out, "driven by Silicon Valley and its real estate and finance sectors."

An anonymous reader shared this report from the Washington Post: The acting U.S. attorney for the District of Columbia sent a letter to the nonprofit that runs Wikipedia, accusing the tax-exempt organization of "allowing foreign actors to manipulate information and spread propaganda to the American public." In the letter dated April 24, Ed Martin said he sought to determine whether the Wikimedia Foundation's behavior is in violation of its Section 501(c)(3) status. Martin asked the foundation to provide detailed information about its editorial process, its trust and safety measures, and how it protects its information from foreign actors. "Wikipedia is permitting information manipulation on its platform, including the rewriting of key, historical events and biographical information of current and previous American leaders, as well as other matters implicating the national security and the interests of the United States," Martin wrote. "Masking propaganda that influences public opinion under the guise of providing informational material is antithetical to Wikimedia's 'educational' mission." Google prioritizes Wikipedia articles, the letter points out, which "will only amplify propaganda" if the content contained in Wikipedia articles "is biased, unreliable, or sourced by entities who wish to do harm to the United States." And as a U.S.-based non-profit, Wikipedia enjoys tax-exempt status while its board "is composed primarily of foreign nationals," the letter argues, "subverting the interests of American taxpayers." While noting Martin's concerns about "allowing foreign actors to manipulate information and spread propaganda," the Washington Post also notes that before being named U.S. attorney, "Martin appeared on Russia-backed media networks more than 150 times, The Washington Post reported last week...." Additional articles about the letter here and here.
