  • FBI Looks Into Dead or Missing Scientists Tied To Sensitive US Research
    by BeauHD on 22/04/2026 at 7:00 am

    Federal authorities are now reviewing a string of deaths and disappearances involving scientists tied to sensitive U.S. aerospace and nuclear work, though officials have not established any confirmed link between the cases. The FBI says it "is spearheading the effort to look for connections into the missing and deceased scientists," adding that it "is working with the Department of Energy, Department of War, and with our state ... and local law enforcement partners to find answers." The Republican-led House Oversight Committee also announced an investigation into the reports. CNN reports: A nuclear physicist and MIT professor fatally shot outside his Massachusetts residence. A retired Air Force general missing from his New Mexico home. An aerospace engineer who disappeared during a hike in Los Angeles. These are among at least 10 individuals connected to sensitive US nuclear and aerospace research who have died or disappeared in recent years, prompting concerns whether they are connected and fueling speculation online about the possibility of nefarious activity. [...] The Defense Department said only that it would respond to the committee directly, and the Department of Energy referred questions to the White House. In a post on X, NASA said it is "coordinating and cooperating with the relevant agencies" in relation to the scientists. "At this time, nothing related to NASA indicates a national security threat," NASA spokesperson Bethany Stevens said. The cases vary widely in circumstance. Some involve unsolved homicides, while others are missing persons cases with no signs of foul play. In at least two instances, families have pointed to preexisting medical conditions or personal struggles as explanations. Authorities have not established any links between the cases. The White House said last week it is also working with federal agencies to probe any potential links between the deaths and disappearances, with President Donald Trump referring to the matter as "pretty serious stuff." "The United States has thousands of nuclear scientists and nuclear experts," said Rep. James Walkinshaw, a Democrat who also serves on the Oversight Committee. "It's not the kind of nuclear program that potentially a foreign adversary could significantly impact by targeting 10 individuals." Read more of this story at Slashdot.

  • SpaceX Strikes Deal With Coding Startup Cursor For $60 Billion
    by BeauHD on 22/04/2026 at 3:30 am

    An anonymous reader quotes a report from the New York Times: SpaceX, Elon Musk's rocket and satellite company, said on Tuesday that it had struck a deal with the artificial intelligence start-up Cursor that could result in its acquiring the young company for $60 billion. SpaceX is making the deal just as it prepares to go public in what is likely to be one of the largest initial public offerings ever. In a social media post, SpaceX said the combination with Cursor, which makes code-writing software, would "allow us to build the world's most useful" A.I. models. SpaceX added that the agreement gave it the option "to acquire Cursor later this year for $60 billion or pay $10 billion for our work together." It is unclear if the companies plan to consummate the deal before or after SpaceX's I.P.O., which could happen as early as June. [...] Cursor, which has raised more than $3 billion in funding, was founded in 2022 and made waves as a fast-growing A.I. start-up. It was under pressure in recent months after OpenAI and Anthropic announced competing code-writing products that were embraced by tech companies. Cursor had been in talks to raise funding in recent weeks. Read more of this story at Slashdot.

  • Florida Launches Criminal Investigation Into ChatGPT Over School Shooting
    by BeauHD on 21/04/2026 at 11:00 pm

    Florida's attorney general has launched a criminal investigation into OpenAI over allegations that the accused gunman in a shooting at Florida State University last year used ChatGPT to help plan the attack. OpenAI says the chatbot is "not responsible for this terrible crime" and only provided factual information available from public sources. NPR reports: The Republican attorney general, James Uthmeier, said at a press conference in Tampa on Tuesday that accused gunman Phoenix Ikner consulted ChatGPT for advice before the shooting, including what type of gun to use, what ammunition went with it, and what time to go to campus to encounter more people, according to an initial review of Ikner's chat logs. "My prosecutors have looked at this and they've told me, if it was a person on the other end of that screen, we would be charging them with murder," Uthmeier said. "We cannot have AI bots that are advising people on how to kill others." Uthmeier's office is issuing subpoenas to OpenAI seeking information about its policies and internal training materials related to user threats of harm and how it cooperates with and reports crimes to law enforcement, dating back to March 2024. At the press conference, Uthmeier acknowledged the investigation is entering into uncharted territory and is uncertain about whether OpenAI has criminal liability. "We are going to look at who knew what, designed what, or should have done what," he said. "And if it is clear that individuals knew that this type of dangerous behavior might take place, that these types of unfortunate, tragic events might take place, and nevertheless still turned to profit, still allowed this business to operate, then people need to be held accountable." [...] Ikner, 21, is facing multiple charges of murder and attempted murder for the April 2025 shooting near the student union on FSU's Tallahassee campus, where he was a student at the time. His trial is set to begin on Oct. 19. According to court filings, more than 200 AI messages have been entered into evidence in the case. Read more of this story at Slashdot.

  • Mozilla Uses Anthropic's Mythos To Fix 271 Bugs In Firefox
    by BeauHD on 21/04/2026 at 10:00 pm

    BrianFagioli writes: Mozilla says it used an early version of Anthropic's Claude Mythos Preview to comb through Firefox's code, and the results were hard to ignore. In Firefox 150, the team fixed 271 vulnerabilities identified during this effort, a number that would have been unthinkable not long ago. Instead of relying only on fuzzing tools or human review, the AI was able to reason through code and surface issues that typically require highly specialized expertise. The bigger implication is less about one release and more about where this is heading. Security has long favored attackers, since they only need to find a single flaw while defenders have to protect everything. If AI can scale vulnerability discovery for defenders, that dynamic could start to shift. It does not mean zero days disappear overnight, but it suggests a future where bugs are found and fixed faster than attackers can weaponize them. "Computers were completely incapable of doing this a few months ago, and now they excel at it," says Mozilla in a blog post. "We have many years of experience picking apart the work of the world's best security researchers, and Mythos Preview is every bit as capable. So far we've found no category or complexity of vulnerability that humans can find that this model can't." The company concluded: "The defects are finite, and we are entering a world where we can finally find them all." Read more of this story at Slashdot.

  • Framework Laptop 13 Pro Is a Major Overhaul For the Modular, Upgradeable Laptop
    by BeauHD on 21/04/2026 at 9:00 pm

    An anonymous reader quotes a report from Ars Technica: Framework has been selling and shipping its modular, repairable, upgradable Laptop 13 for five years now, and in that time, it has released six distinct versions of its system board, each using fresh versions of Intel and AMD processors (seven versions, if you count this RISC-V one). The laptop around those components has gradually gotten better, too. Over the years, Framework has added higher-resolution screens in both matte and glossy finishes, a slightly larger battery, and other tweaked components that refine the original design. But so far, all of those parts have been totally interchangeable, and the fundamentals of the Laptop 13 design haven't changed much. That changes today with the Framework Laptop 13 Pro, which, despite its name, is less an offshoot of the original Laptop 13 and closer to a ground-up redesign. It includes new Core Ultra Series 3 chips (codenamed Panther Lake), Framework's first touchscreen, a new black aluminum color option, a larger battery, and other significant changes. And while it sacrifices some component compatibility with the original Laptop 13, displays and motherboards remain interchangeable, so Framework Laptop owners can buy the new Core Ultra board and owners of older Framework Laptop boards can pop one into a Pro to benefit from the new battery and screen. At 1.4kg (about 3 pounds), the Laptop 13 Pro is slightly heavier than the Laptop 13's 1.3kg, but it still stacks up well against the 14-inch M5 MacBook Pro (1.55kg, or 3.4 pounds). The Framework Laptop Pro will start at $1,199 for a DIY edition with a Core Ultra 5 325 processor, and no RAM, SSD, or operating system. A prebuilt version with Ubuntu Linux installed will start at $1,499, and Windows 11 will cost another $100 on top of that. A Core Ultra X7 358H version starts at $1,599 for a DIY edition, and a "limited batch" Core Ultra X9 388H version starts at $1,799. A bare motherboard with the Core Ultra 5 325 starts at $449, while a Core Ultra X7 358H board will cost $799. Pre-orders are available now, and begin shipping in June.

  • Job Cuts Driven By AI Are Rising On Wall Street
    by BeauHD on 21/04/2026 at 8:00 pm

    Firms like Bank of America, Citi, Wells Fargo, and others are reporting strong profits while reducing head count and automating more work. "All of them credited A.I. to some degree ... in areas ranging from the so-called back office, where tens of thousands of employees fill out paperwork to comply with various laws and regulations, to the front office, where seven-figure salaried professionals put together complicated financial transactions for corporate clients," reports the New York Times. From the report: Less than four months ago, Bank of America's chief executive, Brian T. Moynihan, volunteered in a TV interview what he would say to his 210,000 employees about the chance of artificial intelligence replacing human work. "You don't have to worry," he said. "It's not a threat to their jobs." Last week, after Bank of America reported $8.6 billion in profit for the first quarter -- $1.6 billion more than the same period a year earlier -- Mr. Moynihan struck a different tone. The bank's bottom line, he said, was helped by shedding 1,000 jobs through attrition by "eliminating work and applying technology," which he repeatedly specified was artificial intelligence. He predicted more of that in the months and years to come. "A.I. gives us places to go we haven't gone," Mr. Moynihan said. The veneer of Wall Street's longstanding assertion -- that A.I. will enhance human work, not replace it -- is rapidly peeling away, as evidenced by the current quarterly earnings season. JPMorgan Chase, Citi, Bank of America, Goldman Sachs, Morgan Stanley and Wells Fargo racked up $47 billion in collective profits, up 18 percent, while shedding 15,000 employees. All of them credited A.I. to some degree with helping cut jobs and automate work in areas ranging from the so-called back office, where tens of thousands of employees fill out paperwork to comply with various laws and regulations, to the front office, where seven-figure salaried professionals put together complicated financial transactions for corporate clients. Unlike executives in Silicon Valley, few major financial figures are stating outright that A.I. is eliminating jobs. Citi, for example, has pledged to shrink its work force by 20,000 people through what one executive described to financial analysts last week as the company's "productivity and efficiency journey." The bank is paying for A.I. software from Anthropic, Google, Microsoft and OpenAI, to automatically read legal documents, approve account openings, send invoices for trades and organize sensitive customer data, among other tasks, according to public statements by bank executives and two people familiar with Citi's systems. Among the recent job cuts at Citi were scores of employees who were part of the bank's "A.I. Champions and Accelerators" program, according to the two people, who were not permitted by the bank to speak publicly. The program involves Citi employees who perform their day jobs while also working to persuade their colleagues to adopt A.I. technologies. Read more of this story at Slashdot.
