The science of how fireflies stay in sync

Engineers have uncovered the mathematical rules fireflies follow to sync up their flashes. Scientists have discovered that male fireflies in a South Carolina swamp follow local interaction rules to synchronize their flashing mating displays. The research is being presented at a meeting of the American Physical Society in Denver.…

Figuring out why AIs get flummoxed by some games

When winning depends on intuiting a mathematical function, AIs come up short. With its Alpha series of game-playing AIs, Google’s DeepMind group seemed to have found a way for its AIs to tackle any game, mastering games like chess and Go by repeatedly playing itself during training. But then…

Magnetars drag spacetime to power superluminous supernovae

Frame-dragging may explain an odd pattern seen in the brightest supernovae. Some of the most extreme explosions in the universe are Type I superluminous supernovae. “They are one of the brightest explosions in the Universe,” says Joseph Farah, an astrophysicist at the University of California, Santa Barbara. For years,…
