  • Ford Rehires 350 Engineers After AI Fails To Preserve Expertise or Train Juniors
    by BeauHD on 25/06/2026 at 5:00 pm

    After Ford's automated quality-control systems and AI tools fell short, the automaker hired 350 veteran engineers over the past three years to mentor younger staff and reprogram the underperforming technology. "Artificial intelligence is a fantastic tool, but it's only as good as the information you use to train it," Charles Poon, Ford's vice president of vehicle hardware engineering, told reporters on a call Wednesday. "Over prior years, we didn't pay as much attention as we should have to the experience of our most knowledgeable engineers that have been with us through many product cycles." Bloomberg reports: Those engineers were "at the heart" of Ford's efforts to turn around quality problems, said Kumar Galhotra, chief operating officer. They now run mandatory meetings that rigorously troubleshoot quality problems and they have reprogrammed AI tools to head off glitches before they happen. "We had been relying more and more on automated quality systems" and not getting the desired results, Galhotra said. "We brought back technical specialists" and "they hunt for failure points before a part ever reaches the plant floor." The return of the veteran engineers at Ford cuts against the prevailing wisdom -- and fear -- that AI will replace all kinds of knowledge workers. But Ford found the machines couldn't replace experience. "Mistakenly we thought that by just introducing artificial intelligence and ingesting the design requirements that we had, that that would produce a high-quality product," Poon said. But "we recognized that for us to enhance some of our automation and machine learning and artificial intelligence tools we needed to ensure that they were trained by the most experienced individuals." As a result of the efforts of the old hands, Ford vaulted above quality stalwarts such as Toyota and Honda on JD Power's bellwether survey that measures the quality of a car during the first three months of ownership. Only luxury brands Porsche and Genesis topped Ford this year. Read more of this story at Slashdot.

  • Micron Locks In Historically High Memory Prices For Five Years
    by BeauHD on 25/06/2026 at 4:00 pm

    Micron has signed 16 "strategic customer agreements" (SCAs) that include a floor price the company says comes with "a very robust gross margin for Micron, well above our peak quarterly margins in any past cycle." Most of the deals run through 2030 and cover about 40% of Micron's revenue. The Register reports: Micron CEO, president and chairman Sanjay Mehrotra explained the SCAs in prepared remarks delivered during the company's Q3 earnings call. He explained that Micron has signed 16 SCAs, most of them covering 2026 to 2030, and that they involve a commitment to buy a certain quantity of product and pay for it in a pricing band that has a floor and a ceiling price. The floor price covers the historically high gross margins mentioned above, and the ceiling price means those who commit to an SCA are insulated if memory prices go even higher. The CEO said 16 customers have signed SCAs and then explained why it's worth locking into the deals even though they bake in such high margins. "Our customers are recognizing that supply shortages in memory and storage will take considerable time to improve," he said. "Even as we expect industry supply to improve gradually in 2028, we currently do not have line of sight as to when memory supply will be able to catch up with increasing demand." Even massive efforts to build new chip fabs aren't much help, he said, because the increasing complexity of new memory types means it takes longer to build factories -- and when they come online there still won't be enough capacity to build both the high-bandwidth memory needed for AI and other types of NAND and DRAM. "Supply is structurally constrained in its growth and ability to meet industry demand, despite our comprehensive efforts to increase supply," he said. Don't assume that SCAs mean your suppliers get price certainty, because Mehrotra said the deals will account for 40 percent of Micron revenue -- meaning the company is reserving most of its inventory to sell at prices it can negotiate. The CEO did have a little good news in the form of predictions that Micron's DRAM output in 2026 will "grow in the low- to mid-20s percentage range, slightly above our prior outlook." He also revealed that the SCAs see customers pay up front, which helps Micron to fund its fab expansions. Read more of this story at Slashdot.

  • Google Starts Lowering Play Store Fees, Making Good On Epic Games Settlement
    by BeauHD on 25/06/2026 at 3:00 pm

    An anonymous reader quotes a report from Ars Technica: Google spent the last few years locked in a legal grudge match with Epic Games, which claimed that Google's stewardship of the Play Store was anticompetitive. Now, the companies are thick as thieves, and Google is beginning to implement app store changes as agreed in its settlement with Epic. The lower developer fees and new payment options that Google promised are rolling out in select markets this month before expanding. [...] Starting on June 30, developers in Europe, the UK, and the US will have access to the new fee structure. This system will split the commission into two components: billing and service fees. The biggest win for small developers is the new flat 10 percent service fee for the first $1 million in earnings every year. Above that, the rate for various transaction types may reach 25 percent on existing installs. Apps installed after June 30 will top out at 20 percent. Developers will finally be allowed to send users outside the Play Store to complete a transaction, too. Google says they can design a choice screen "in accordance with our UX guidelines" to direct users to these external options. Devs pay the standard service fee on these purchases, but they'll avoid the billing fee. All transactions that run through Google's Play Store platform add a 5 percent billing fee -- even the base rate for publishers earning less than $1 million. Google notes that the billing fee is set at 5 percent in the initial markets, but it could be different in other regions. Google will expand the new fee structure globally through September 2027, while also offering reduced fees through updated developer programs. Although the changes may let developers retain more revenue, Google will continue controlling Android distribution and collecting a share of sales as it works toward allowing certified third-party app stores to operate more like the Play Store.

  • New Study Shows That Tall Vehicle Hoods Cause Hundreds More Deaths Per Year
    by BeauHD on 25/06/2026 at 11:00 am

    joshuark shares a report from Car and Driver: A new study conducted by the New York Times shows that the increase in vehicle hood height seen over the last two and a half decades, mainly due to the rise in popularity of large SUVs and trucks, has resulted in several thousand deaths that otherwise may not have happened. The study shows that while automakers and regulators have focused on occupant safety, they have turned a blind eye to pedestrian safety, which has fallen since around 2009. Researchers looked at four main datasets in their investigation: crash test data from the National Highway Traffic Safety Administration's (NHTSA) Crash Report Sampling System (CRSS) from 2016 to 2024; NHTSA's Fatality Analysis Reporting System (FARS); vehicle measurement data from Expert AutoStats; and vehicle registration data from S&P Global from 2002 to 2024. The researchers concluded that the increased danger to pedestrians is caused by two main culprits. First, large SUVs and trucks have taller hoods, raising the point of impact above most people's center of gravity and pushing them to the ground, typically hard asphalt, rather than up and onto the hood, which is designed to absorb impacts. Second, with larger A-pillars designed to protect occupants in rollover crashes, modern cars tend to have larger blind spots than cars sold at the turn of the century (presuming the 21st century). The shift toward vehicles with taller hoods led to roughly 3000 deaths between 2016 and 2024. This number is conservative because it does not include crashes that take place in parking lots, driveways, or private roads, which aren't part of the federal database. The data also showed an estimated 2.8 percent increase in the odds of a pedestrian fatality for every one-inch increase in vehicle hood height. Between two different scenarios, one decreasing the hood height of every vehicle in the dataset by 3 inches, and the second using a random sampling of hood heights from 2002 across 10,000 simulated crashes, between 2624 (for scenario two) and 3077 (for scenario one) lives could have been saved from 2016 to 2024.

  • NASA Rover Detects Potential Signatures of Ancient Microbial Life On Mars
    by BeauHD on 25/06/2026 at 7:00 am

    NASA's Perseverance rover has detected complex organic carbon in ancient Martian mudstones. The measurements were taken by the rover's Sherloc instrument and the organic carbon that was identified was from the Bright Angel outcrop, "a dried-up river that carried water into the planet's Jezero crater billions of years ago," notes The Guardian. From the report: The form of carbon detected, known as macromolecular carbon or MMC, can originate from living organisms. Geological processes can also produce the material, meaning its detection does not amount to proof of past Martian life. Dr Ashley Murphy at the Planetary Science Institute in Arizona said MMC can be found in different settings and types of rocks. "It may originate from biological sources such as fossilized organic matter found in microbial mats and coal," she said, but could also form in reactions between rocks and water or arrive on impacting meteorites. The mudstone rocks from the Bright Angel outcrop caused a stir in 2024 when the Perseverance rover discovered intriguing surface spots and nodules that resemble features produced by fossilized microbes on Earth. When the scientific details were published last year, Sean Duffy, the former acting head of Nasa, said: "This very well could be the clearest sign of life that we've ever found on Mars." [...] The discovery means Nasa rovers have now found organic-bearing mudstones more than 2,000 miles apart on Mars. The others were reported by the Curiosity rover which is exploring the planet's Gale crater. It "indicates that the habitability of Mars, and the availability of organics, may have been widespread across the planet billions of years ago," the authors write in Science Advances.

  • Stripe, Anthropic, and OpenAI Are Backing Effort To Stop Respiratory Infections
    by BeauHD on 25/06/2026 at 3:30 am

    An anonymous reader quotes a report from MIT Technology Review: [T]he payment company Stripe, founded by brothers Patrick and John Collison, says it will fund a new $500 million nonprofit whose goal is preventing both the common cold and the flu. Its eventual aim is to get rid of respiratory viruses altogether. The new organization, called Intercept, will use grants and investments to back prevention approaches, including vaccines, as well as large-scale air-cleaning systems for schools, offices, and other public spaces. In addition to Stripe, other funders include Anthropic, Flu Lab, and the OpenAI Foundation, as well as Bill Gates and several traders at the quantitative investing fund Jane Street Capital, according to an Intercept spokesperson. "I think we treat respiratory infections as a minor nuisance, but have really underweighted the burden that they impose on society," says Nan Ransohoff, the Stripe executive leading the initiative along with Charlie Petty, a venture capitalist who joined Stripe this year. On average, people spend 5% of their lifetime fighting a cold or the flu, according to Ransohoff. Despite that, drug companies put relatively little effort into preventing colds. Part of the problem is that the sniffles are caused by more than 200 different viruses, according to the American Lung Association, with rhinoviruses being the most common culprits. There are so many that it typically doesn't pay to try to stop any one of them with a vaccine. "When pharma companies look at it, it's not as attractive as other things they could work on," says Ransohoff. "So it hasn't attracted the resources." [...] The project takes inspiration from efforts to fight the covid-19 virus, where Veesler's group was among those involved in the speedy development of vaccines, antiviral drugs, and antibodies. According to Ransohoff, Intercept's advisors will include Peter Marks, a former top FDA official, as well as Moncef Slaoui, the pharmaceutical executive who led the US coronavirus vaccine effort, Operation Warp Speed. A key challenge for Intercept will be coming up with ways to counter many viruses at one time. That accounts for the interest in air-cleaning technology, such as using strong ultraviolet light to inactivate viruses. The idea, the group says, is to remove them from the air in the same way municipalities remove impurities from the water supply before it's piped to people's homes.
