Researchers have previously discovered that certain small mammals, including the common shrew and European mole, reversibly shrink their body mass, skull size and brain mass in winter, with regrowth seen in the spring – a strategy that has been named Dehnel’s phenomenon...

Star’s extreme proximity to Sagittarius A means it could open new window onto black hole’s fundamental properties Astronomers have detected the fastest known star in the Milky Way, hurtling around the supermassive black hole at the heart of the galaxy. The star, called S301, travels at about 25,000km (15,500 miles) per second, 100,000 times faster than a commercial plane. It is also the closest known star to the Milky Way’s central black hole, Sagittarius A, approaching it around the distance of Saturn to the Sun...
