An anonymous reader quotes a report from Barron’s: Walmart is signing a long-term contract to buy nuclear power for the first time ever, a promising sign that the industry’s future is supported by more than just the AI data center boom. The retail giant agreed on Tuesday to buy power from a nuclear plant in Illinois owned by Constellation Energy for its operations in the area, including its stores and a high-tech warehouse in Illinois that stores and sorts perishable food.

Walmart will buy 176 megawatts of power from the plant over a 15-year period, or enough power to serve around 150,000 homes. The Walmart deal will allow Constellation to expand the capacity of the Illinois plant by 30 megawatts, a process known as an uprate, which can involve replacing older equipment and improving efficiency. Walmart, which has pledged to eliminate net carbon emissions from its U.S. operations by 2040, will also receive the environmental attributes associated with the nuclear energy, which generates electricity without carbon emissions.

OpenAI and Broadcom have unveiled Jalapeno, OpenAI’s first custom AI chip, designed primarily to handle inference for ChatGPT and other services. It’s a major step in OpenAI’s plan to “build the full stack behind its models and products,” says OpenAI. “By designing more of the stack ourselves, we can serve more intelligence with greater efficiency and keep pushing advanced AI toward broader access.” CNBC reports: The chip with Broadcom is an ASIC, which industry experts say is less flexible than Nvidia’s GPU, but is also less expensive and can be designed for specific AI tasks. OpenAI said that it designed the chip in nine months, and that it also crafted large parts of the computer system where it will be used.

The companies are calling the chip an “Intelligence Processor” and describe it as the first “AI accelerator” in a platform they’re building “to make advanced AI faster, more reliable, and more accessible to more people.” […] A physical sample of the new chip will be delivered to OpenAI on Wednesday. The companies said they’re aiming for initial deployment of the Jalapeno chips by the end of 2026, “expanding in the years ahead.”

Slate Auto says its stripped-down electric pickup will start at $24,950 before fees, with the base model’s estimated range increased from 150 to about 205 miles. The company has started taking preorders on Wednesday. “The aggressive pricing — half the average cost of a new car in the United States — puts Slate in position to capture a share of the lowest end of the new car market, which has few gas and fewer electric options these days,” reports TechCrunch. From the report: The price reveal comes more than a year after Slate Auto emerged from stealth. Since then, the company has been steadily detailing the extremely basic, transforming EV, which starts as a two-seater pickup truck, but can be modified into a five-seater SUV. The SUV version will start at $29,950, Slate said Wednesday. Slate has said the conversion can be done by professionals or by owners themselves. On Wednesday, it finally showed off some of the first of its “Slate University” how-to videos, which guide people through the steps for doing everything from the SUV conversion to adding headlight covers.

Everything else about the truck is bare, though it’s customizable. It has hand-crank windows, lacks an infotainment system, and all orders start with the same gray composite material, with no paint options, as Slate plans to let buyers order customizable wraps for the vehicle. That likely helps cut out a major cost center, as factory paint shops can run in the hundreds of millions of dollars. The company did not offer more details about the buying process. Slate has said it “won’t have traditional dealerships,” and plans to sell directly to customers, similar to other EV companies like Tesla, Rivian, and Lucid Motors.

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.
