Physicists measured the rotation of the Earth using quantum entanglement

Red squiggles representing photons are sent into a loop representing the optical fiber in an interferometer, which surrounds Earth on a starry backdrop

The rotation of the Earth has been measured many times – but never like this. At first, scientists used entangled quantum particles called photons to detect the speed at which the globe spins. The achievement is a step toward investigating one of physics’ greatest mysteries: how the tiny world of quantum physics interacts with gravity. … Read more

Some bacteria in your mouth can divide into 14 cells at once

A whitish growth of Corynebacterium matruchotii bacteria

Among the more than 500 species of bacteria that thrive in the human mouth, one seems to play by its own rules. Instead of reproducing by dividing into two, as most bacteria do, Corynebacterium matruchotii divides into 14 cells simultaneously, researchers report on Sept. 10. Proceedings of the National Academy of Sciences. This video shows … Read more
