MIT engineers have found a way to give chip-based lidar a wider, clearer view without relying on moving parts。 Their design uses differently shaped antennas that can sit close together without scrambling one another’s signals。 In tests, the system sharply reduced interference while steering a single precise beam across a broad field of view
A giant planet had been hiding inside one of astronomy’s most closely studied planetary systems, concealed by a bright disk of cosmic dust。 Webb revealed Beta Pictoris d through atmospheric traces of carbon monoxide, water vapor, and methane, showcasing a promising new method for finding elusive exoplanets
Scientists have found a way to revive vancomycin, a powerful antibiotic that some dangerous bacteria have learned to resist。 Instead of creating an entirely new drug, researchers paired vancomycin with a small molecule called pghi-4, which blocks a bacterial enzyme linked to resistance。 The combination restored the antibiotic’s ability to kill drug
NASA is preparing for future astronaut landings on the Moon with an unusually ambitious orbital rehearsal。 During Artemis III in 2027, Orion astronauts will rendezvous and dock separately with prototype lunar landers from Blue Origin and SpaceX, allowing crews and ground teams to test the complex maneuvers needed for later missions
Researchers found that specific brain circuits help decide which jobs bees perform as they age。 When those circuits were switched off, older worker bees began caring for the queen again instead of carrying out their normal later-life duties。 The findings reveal that a bee colony’s complex division of labor may be guided by neural switches hidden in
Deck out your room and make class a cinch with these WIRED-tested favorites
Researchers discovered a proton-assisted mechanism that greatly improves how triplet energy moves between quantum dots and nearby molecules。 The proton briefly shifts position, helps coordinate electron movement, and then returns to where it started。 This quantum-driven shuttle could offer a powerful new way to tune solar cells, lasers, and catalyt
