An anonymous reader quotes a report from MIT Technology Review: Physicists have created a new type of radar that could help improve underground imaging, using a cloud of atoms in a glass cell to detect reflected radio waves. The radar is a type of quantum sensor, an emerging technology that uses the quantum-mechanical properties of objects as measurement devices. It's still a prototype, but its intended use is to image buried objects in situations such as constructing underground utilities, drilling wells for natural gas, and excavating archaeological sites. [...] The glass cell that serves as the radar's quantum component is full of cesium atoms kept at room temperature. The researchers use lasers to get each individual cesium atom to swell to nearly the size of a bacterium, about 10,000 times bigger than the usual size. Atoms in this bloated condition are called Rydberg atoms. When incoming radio waves hit Rydberg atoms, they disturb the distribution of electrons around their nuclei. Researchers can detect the disturbance by shining lasers on the atoms, causing them to emit light; when the atoms are interacting with a radio wave, the color of their emitted light changes. Monitoring the color of this light thus makes it possible to use the atoms as a radio receiver. Rydberg atoms are sensitive to a wide range of radio frequencies without needing to change the physical setup... This means a single compact radar device could potentially work at the multiple frequency bands required for different applications. [Matthew Simons, a physicist at the National Institute of Standards and Technology (NIST), who was a member of the research team] tested the radar by placing it in a specially designed room with foam spikes on the floor, ceiling, and walls like stalactites and stalagmites. The spikes absorb, rather than reflect, nearly all the radio waves that hit them. This simulates the effect of a large open space, allowing the group to test the radar's imaging capability without unwanted reflections off walls.The researchers placed a radio wave transmitter in the room, along with their Rydberg atom receiver, which was hooked up to an optical table outside the room. They aimed radio waves at a copper plate about the size of a sheet of paper, some pipes, and a steel rod in the room, each placed up to five meters away. The radar allowed them to locate the objects to within 4.7 centimeters. The team posted a paper on the research to the arXiv preprint server in late June.

Researchers at Kyushu University have developed a solid-oxide fuel cell that operates at just 300C, less than half the usual operating temperature. The team was able to do this by engineering a "ScO6 highway" in the electrolyte, allowing protons to move quickly without losing performance. "The team expects that their new findings will lead to the development of low-cost, low-temperature SOFCs and greatly accelerate the practical application of these devices," said the researchers in a press release. Interesting Engineering reports: "While SOFCs are promising due to their high efficiency and long lifespan, one major drawback is that they require operation at high temperatures of around 700-800C (1292F-1472F)," added the researchers in a press release. Such heat requires costly, specialized heat-resistant materials, making the technology expensive for many applications. A lower operating temperature is expected to reduce these manufacturing costs. The team's success comes from re-engineering the fuel cell's electrolyte, the ceramic layer that transports protons (hydrogen ions) to generate electricity. Previously, scientists faced a trade-off. Adding chemical dopants to an electrolyte increases the number of available protons but also tends to clog the material's crystal lattice, slowing proton movement and reducing performance. The Kyushu team worked to resolve this issue. "We looked for oxide crystals that could host many protons and let them move freely -- a balance that our new study finally struck," stated Yamazaki. They found that by doping two compounds, barium stannate (BaSnO3) and barium titanate (BaTiO3), with high concentrations of scandium (Sc), they could create an efficient structure. Their analysis showed that the scandium atoms form what the researchers call a "ScO6 highway." This structure creates a wide and softly vibrating pathway through the material. "This pathway is both wide and softly vibrating, which prevents the proton-trapping that normally plagues heavily doped oxides," explained Yamazaki. The resulting material achieves a proton conductivity of more than 0.01 S/cm at 300C, a performance level comparable to conventional SOFC electrolytes that run at more than double the temperature. The research has been published in the journal Nature Materials.

After four weather-related delays, Amazon successfully launched 24 more Kuiper internet satellites aboard a SpaceX Falcon 9, bringing its total to 102. CNBC reports: SpaceX's Starlink is currently the dominant provider of low-earth orbit satellite internet, with a constellation of roughly 8,000 satellites and about 5 million customers worldwide. Amazon is racing to get more of its Kuiper satellites into space to meet a deadline set by the Federal Communications Commission. The FCC requires that Amazon have about 1,600 satellites in orbit by the end of July 2026, with the full 3,236-satellite constellation launched by July 2029. Amazon has booked up to 83 launches, including three rides with SpaceX. While the company is still in the early stages of building out its constellation, Amazon has already inked deals with governments as it hopes to begin commercial service later this year.

An anonymous reader quotes a report from Ars Technica: In recent months, the AI industry has started moving toward so-called simulated reasoning models that use a "chain of thought" process to work through tricky problems in multiple logical steps. At the same time, recent research has cast doubt on whether those models have even a basic understanding of general logical concepts or an accurate grasp of their own "thought process." Similar research shows that these "reasoning" models can often produce incoherent, logically unsound answers when questions include irrelevant clauses or deviate even slightly from common templates found in their training data. In a recent pre-print paper, researchers from the University of Arizona summarize this existing work as "suggest[ing] that LLMs are not principled reasoners but rather sophisticated simulators of reasoning-like text." To pull on that thread, the researchers created a carefully controlled LLM environment in an attempt to measure just how well chain-of-thought reasoning works when presented with "out of domain" logical problems that don't match the specific logical patterns found in their training data. The results suggest that the seemingly large performance leaps made by chain-of-thought models are "largely a brittle mirage" that "become[s] fragile and prone to failure even under moderate distribution shifts," the researchers write. "Rather than demonstrating a true understanding of text, CoT reasoning under task transformations appears to reflect a replication of patterns learned during training." [...] Rather than showing the capability for generalized logical inference, these chain-of-thought models are "a sophisticated form of structured pattern matching" that "degrades significantly" when pushed even slightly outside of its training distribution, the researchers write. Further, the ability of these models to generate "fluent nonsense" creates "a false aura of dependability" that does not stand up to a careful audit. As such, the researchers warn heavily against "equating [chain-of-thought]-style output with human thinking" especially in "high-stakes domains like medicine, finance, or legal analysis." Current tests and benchmarks should prioritize tasks that fall outside of any training set to probe for these kinds of errors, while future models will need to move beyond "surface-level pattern recognition to exhibit deeper inferential competence," they write.

AmiMoJo shares a report from the BBC: A French nuclear plant temporarily shut down on Monday due to a "massive and unpredictable presence of jellyfish" in its filters, its operator said. The swarm clogged up the cooling system and caused four units at the Gravelines nuclear power plant to automatically switch off, energy group EDF said. The plant is cooled from a canal connected to the North Sea -- where several species of jellyfish are native and can be seen around the coast when the waters are warm. According to nuclear engineer Ronan Tanguy, the marine animals managed to slip through systems designed to keep them out because of their "gelatinous" bodies. "They were able to evade the first set of filters then get caught in the secondary drum system," he told the BBC. Mr Tanguy, who works at the WNA, said this will have created a blockage which reduced the amount of water being drawn in, prompting the units to shut down automatically as a precaution. He stressed that the incident was a "non-nuclear event" and more a "nuisance" for the on-site team to clean up. For local people, there would be no impact on their safety or how much energy they could access: "They wouldn't perceive it as any different to any other shut-down of the system for maintenance."

Legal scholar Victoria Haneman argues that U.S. law should grant estates a time-limited right to delete a deceased person's data so they can't be recreated by AI without their consent. "Digital resurrection by or through AI requires the personal data of the deceased, and the amount of data that we are storing online is increasing exponentially with each passing year," writes Haneman in an article published earlier this year in the Boston College Law Review. "It has been said that data is the new uranium, extraordinarily valuable and potentially dangerous. A right to delete will provide the decedent with a time-limited right for deletion of personal data." The Register reports: A living person may have some say on the matter through the control of personal digital documents and correspondence. But a dead person can't object, and US law doesn't offer the dead much data protection in terms of privacy law, property law, intellectual property law, or criminal law. The Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), a law developed to help fiduciaries deal with digital files of the dead or incapacitated, can come into play. But Haneman points out that most people die intestate (without a will), leaving matters up to tech platforms. Facebook's response to dead users is to allow anyone to request the memorialization of an account, which keeps posts online. As for RUFADAA, it does little to address digital resurrection, says Haneman. The right to publicity, which provides a private right of action against unauthorized commercial use of a person's name, image, or likeness, covers the dead in about 25 states, according to Haneman. But the monetization of publicity rights has proven to be problematic. Haneman says that there are some states where it's theoretically possible to be prosecuted for libeling or defaming the deceased, such as Idaho, Nevada, and Oklahoma, but adds that such prosecutions have declined because they tread upon the constitutional right to free expression. [...] A recent California law, the Delete Act, which took effect last year, is the first to offer a way for the living to demand the deletion of personal data from data brokers in one step. But according to Haneman, it's unclear whether the text of the law will be extended to cover the dead -- a possibility think tank Aspen Tech Policy Hub supports [PDF]. Haneman argues that a data deletion law for the dead would be grounded in laws governing human remains, where corpses receive protection against abuse despite being neither a person nor property. "The personal representative of the decedent has the right to destroy all physical letters and photographs saved by the decedent; merely storing personal information in the cloud should not grant societal archival rights," she argues. "A limited right of deletion within a twelve-month window balances the interests of society against the rights of the deceased."

Just days after demanding Intel CEO Lip-Bu Tan resign over his past ties to China, President Trump reversed course, calling Tan a "success" following a White House meeting. "I met with Mr. Lip-Bu Tan, of Intel, along with Secretary of Commerce, Howard Lutnick, and Secretary of the Treasury, Scott Bessent," Trump wrote in a post on Truth Social. "The meeting was a very interesting one. His success and rise is an amazing story. Mr. Tan and my Cabinet members are going to spend time together, and bring suggestions to me during the next week. Thank you for your attention to this matter!" CNBC reports: Tan has been an Intel director since 2022, and in March he replaced Pat Gelsinger as CEO. Last week Sen. Tom Cotton, R-Ark., questioned Tan's ties to China. Cotton brought up a past criminal case involving Cadence Design, where Tan had been CEO, and asked whether Intel required Tan to divest from positions in chipmakers linked to the Chinese Communist Party, the People's Liberation Army and any other concerning entities in China. Trump's latest message marks a stark change in tone from last week. In a Truth Social post on Thursday, the president wrote that Tan "is highly CONFLICTED and must resign, immediately. There is no other solution to this problem." Intel said in a comment later that day that the company, directors and Tan are "deeply committed to advancing U.S. national and economic security interests."

An anonymous reader quotes a report from Seeking Alpha: General Motors is reviving its autonomous driving program, tapping former Cruise employees to help design a driverless car for consumers. Under the helm of former Tesla autopilot head Sterling Anderson, GM is moving ahead with a driverless, eyes-free, vehicle with the ultimate goal of developing a car without a person at the wheel, according to a meeting between Anderson and employees revealed to Bloomberg. Anderson reportedly said plans include rehiring Cruise employees, and adding staff at GM's Mountain View, California office. Currently, LiDAR-equipped vehicles are collecting data on public roads for the development of GM's driverless vehicles, GM spokesperson Chaiti Sen told Bloomberg, with the goal of building simulation models that will guide development. GM (GM) shuttered its majority-owned, money-losing, Cruise robotaxi business late last year and let go of ~1,000 Cruise employees, after a pedestrian accident led to the grounding of its entire fleet and regulatory scrutiny. At the time, the company said it was pivoting away from robotaxis to the development of hands-free driving for personal vehicles.

Prosus has secured conditional approval from the European Union for its $4.8âbillion (4.1 billion euros) acquisition of Just Eat Takeaway, after agreeing to sell down its 27.4% stake in Delivery Hero. Reuters reports: Amsterdam-headquartered Prosus, which is majority owned by South Africa's Naspers, announced the deal in February, banking on its artificial intelligence capability to boost Just Eat Takeaway, Europe's biggest meal delivery company. The European Commission, which acts as the EU competition enforcer, said Naspers offered to significantly reduce its 27.4% stake in Delivery Hero to below a specified very low percentage within 12 months. Naspers also pledged not to exercise the voting rights with its remaining limited stake in Delivery Hero and also not to increase its stake beyond the specified maximum level. It will not recommend or propose any person to Delivery Hero's management and supervisory boards. Prosus said the EU decision was the final regulatory approval needed to close the offer which ends on October 1 and that if all offer conditions including the acceptance threshold for the deal are met by that date, it will declare its offer unconditional within three business days. "Our ambition is clear: to build a true European tech champion and lead the next chapter in food delivery innovation," Prosus CEO Fabricio Bloisi said in a statement. "This decision also sends a clear warning to an industry with recent antitrust issues: we won't tolerate any anti-competitive behaviour that may harm consumers," she said. After the deal is complete, Prosus will become the world's fourth-largest food delivery company after Meituan, DoorDash, and Uber.

In an unusual arrangement to secure export licenses, Nvidia and AMD have agreed to give the U.S. government 15% of revenue from certain chip sales to China. The Associated Press reports: The Trump administration halted the sale of advanced computer chips to China in April over national security concerns, but Nvidia and AMD revealed in July that Washington would allow them to resume sales of the H20 and MI308 chips, which are used in artificial intelligence development. President Trump confirmed the terms of the unusual arrangement in a Monday press conference while noting that he originally wanted 20% of the sales revenue when Nvidia asked to sell the "obsolete" H20 chip to China. The president credited Nvidia CEO Jensen Huang for negotiating him down to 15%. "So we negotiated a little deal. So he's selling a essentially old chip," Trump said. Nvidia did not comment about the specific details of the agreement or its quid pro quo nature, but said they would adhere to the export rules laid out by the administration. "We follow rules the U.S. government sets for our participation in worldwide markets. While we haven't shipped H20 to China for months, we hope export control rules will let America compete in China and worldwide," Nvidia wrote in a statement to the AP. "America cannot repeat 5G and lose telecommunication leadership. America's AI tech stack can be the world's standard if we race."

An anonymous reader quotes a report from the Detroit Free Press: Ford is announcing the creation of a new electric vehicle production system and a new EV platform that will allow the automaker to more efficiently bring several lower-cost EVs to market, the first of which will be a midsize, four-door electric pickup that seats five, to launch in 2027. That pickup, which is expected to start around $30,000, will be assembled at Ford's Louisville Assembly Plant for U.S. and export markets. The Dearborn-based automaker said it will invest $2 billion to retool the Louisville plant starting later this year. [...] Ford's investment in Louisville Assembly is in addition to Ford's previously announced $3 billion commitment for BlueOval Battery Park in Marshall, Michigan, where Ford will make the prismatic LFP batteries, starting next year, for the midsize electric pickup. Together, the nearly $5 billion investments mean Ford expects to create or secure nearly 4,000 direct jobs while strengthening the domestic supply chain with dozens of new U.S.-based suppliers. Ford executives and Kentucky officials also introduced on Monday, Aug. 11, the new Ford Universal EV Production System, which they said will simplify production and ease operations for workers. Ford leaders also announced the creation of the Ford Universal Electric Vehicle Platform, which will enable the development of "a family of affordable electric vehicles produced at scale." The vehicles will be software-defined with over-the-air updates to keep improving the vehicles over time. "We took a radical approach to solve a very hard challenge: Create affordable vehicles that are breakthrough in every way that matters design, technology, performance, space and cost of ownership and do it with American workers," Ford CEO Jim Farley said in a statement. "Nobody wants to see another good college try by a Detroit automaker to make an affordable vehicle that ends up with idled plants, layoffs and uncertainty." Farley has teased this announcement since Ford's second-quarter earnings when he said Ford would have a "Model-T moment" on Aug. 11. He's referring to the classic vehicle that helped turn Ford into a mass market automaker and perfect the assembly line process. At that time, Farley said it was critical that Ford unveil an EV strategy that would position it to make money selling the electric cars and effectively compete against the Chinese, who are known for making high-quality, desirable and affordable EVs. "So, this has to be a good business," Farley said of Ford's investments in the new process and platform. "From Day 1, we knew there was no incremental path to success. We empowered a tiny skunkworks team three time zones away from Detroit. We reinvented the line. And we are on a path to be the first automaker to make prismatic LFP batteries in the U.S. We will not rely on imports." Ford says its new Universal Electric Vehicle Platform "reduces parts by 20% versus a typical vehicle, with 25% fewer fasteners, 40% fewer workstations dock-to-dock in the plant and 15% faster assembly time." The new EV pickup built using this platform is targeting a "starting MSRP at about $30,000, roughly the same as the Model T when adjusted for inflation," adds Farley. He shared additional details in an interview with Wired, such as how the automaker hired Tesla veterans Doug Field (who also helped lead Apple's now-defunct EV project) and Alan Clarke. "Turns out, Doug and Alan and the team built a propulsion system that was like Apollo 13, managed down to the watt so that our battery could be so much smaller than BYD's," said Farley.

An anonymous reader shares a report: Starbucks patrons in South Korea are setting up de facto offices at the coffee chain, bringing along their desktop computers and printers. The company implemented a new policy banning bulky items from store locations. In South Korea, where office space is scant, remote workers are using cafes as a cheap place to work. Starbucks South Korea is experiencing this exact phenomenon and is now banning patrons from bringing in large pieces of work equipment, treating the cafes like their own amenity-stuffed office space. "While laptops and smaller personal devices are welcome, customers are asked to refrain from bringing desktop computers, printers, or other bulky items that may limit seating and impact the shared space," a Starbucks spokesperson told Fortune in a statement.

theodp writes: The New York Times reports from the CS grad job-seeking trenches: Growing up near Silicon Valley, Manasi Mishra remembers seeing tech executives on social media urging students to study computer programming. "The rhetoric was, if you just learned to code, work hard and get a computer science degree, you can get six figures for your starting salary," Ms. Mishra, now 21, recalls hearing as she grew up in San Ramon, Calif. Those golden industry promises helped spur Ms. Mishra to code her first website in elementary school, take advanced computing in high school and major in computer science in college. But after a year of hunting for tech jobs and internships, Ms. Mishra graduated from Purdue University in May without an offer. "I just graduated with a computer science degree, and the only company that has called me for an interview is Chipotle," Ms. Mishra said in a get-ready-with-me TikTok video this summer that has since racked up more than 147,000 views. Some graduates described feeling caught in an A.I. "doom loop." Many job seekers now use specialized A.I. tools like Simplify to tailor their resumes to specific jobs and autofill application forms, enabling them to quickly apply to many jobs. At the same time, companies inundated with applicants are using A.I. systems to automatically scan resumes and reject candidates.
