AI-generated imageCutting a slow, error-prone control process down to a single cycle could remove a major obstacle on the way to reliable quantum computers.
AI-generated imageA sudden mass failure of ice and rock high in the Himalayas shows how melting glaciers and unstable mountain slopes can combine into disasters that current warning systems cannot catch.
AI-generated imageModels suggest the ocean region that soaks up the most human carbon dioxide could flip into a major source of it for centuries after net zero, complicating hopes that carbon removal can quickly undo warming.
AI-generated imageThe discovery points to an overlooked layer of biology that may show how cells cooperate, compete, and possibly fuel cancer growth.
AI-generated imageA method gentler than CRISPR can correctly fix a disease gene in every cell of an embryo, but it also triggers unplanned changes elsewhere, keeping the approach far from clinical use.
AI-generated imageA pilot study found the new test caught nearly all true amoxicillin allergies, at a time when most people who believe they are allergic to penicillins are not.
AI-generated imageTracking the chemical fingerprint of nitrogen shows fertilizer runoff surges into the Gulf during wet weather, adding to a decades-long pattern of nutrient pollution and warming that other research links to coral and reef stress.
AI-generated imageTwo hard-to-recycle plastics have lacked practical enzymatic treatments, and a broad new screen has turned up a dozen enzymes that attack both, including forms and thicknesses no previous enzyme handled.
AI-generated imageThree separate research efforts suggest that mechanical vibrations, once seen as a threat to fragile quantum states, can instead be used to connect and shield them.
