A newly discovered turning point in the Sun’s 11-year cycle could allow scientists to predict future solar activity years earlier than before。 At this “switch-off” point, the most violent space weather abruptly ends, and the remaining number of sunspots offers clues about the next cycle’s strength。 Early projections suggest Solar Cycle 26 may be mo
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
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

Astronomers have found the first confirmed atmosphere around a rocky planet in another star’s habitable zone。 The planet, LHS 1140 b, revealed its atmosphere through helium slowly leaking into space。 Located 48 light-years away, the world may have preserved its atmosphere for billions of years, making it a promising target in the search for potenti
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
