Cats can identify each other based on the scent of their pee, and researchers have just decoded the secret “messages” that make that possible. A group of chemicals called branched-chain fatty acids (BFAs) help give cats their unique scent marks, a new study found. Unusual fat droplets in the cats’ kidneys likely help them maintain […]

IBM has revealed a new modular, ultracold system designed to link hundreds of quantum computer chips together to solve one of the field’s biggest infrastructure bottlenecks. The company says its new “quantum fridges” will let it deliver the world’s first fault-tolerant quantum computer in 2029. These stable systems use quantum error correction techniques to fix

Practically all modern computers, from the cheap microcontroller in your dishwasher to high-tech hardware crunching numbers for artificial intelligence systems, rely on versions of the same technology: slabs of silicon patterned with microscopic structures called transistors. Electronic circuits containing transistors can rapidly and reliably toggle between two states, usually labeled “0” and “1.” That enables

Archaeologists in the Scottish Highlands have discovered the 2,000-year-old burial of an adult in a possible ritual well. The burial may have been made during a closing ceremony when the well was abandoned. Archaeologists discovered the enigmatic grave during expansion of a quarry in northern Scotland, according to a statement from Highland Archaeology Services that

Controversial wellness products called peptides are rising in popularity as they’re touted by leaders like Health and Human Services Secretary Robert F. Kennedy Jr. While some peptides — including drugs like Ozempic — have been rigorously tested and approved by the Food and Drug Administration (FDA), many peptides are untested and unregulated. These untested peptides
