It’s dawn in the savanna, and its inhabitants are already starting to stir. Giraffes are munching on the tops of trees, and gazelles are ambling through the shrub-spotted grasslands. Elephants are trampling the thirsty turf, sending sprays of dust into the dry savannah air, and buffalos are bent with their snuffling snouts to the ground. Rarely are any of these grazing animals alone, at this time of day or any other. And though they typically travel in herds, including tens to hundreds to thou ...read more

These fall migrations are both a simple fact of life for many avian species, and an epic adventure that takes them halfway across the globe.Seasonal migrations allow birds to take advantage of prime habitats for feeding and reproducing in the warmer summer months before escaping the deadly cold of winter.

A supercomputer at the Oak Ridge National Laboratory in Tennessee called Summit takes up the same floor space as a couple of tennis courts, and weighs more than a large commercial aircraft. In certain cases, the machine can perform about a billion calculations per second, allowing it to simulate complex systems in physics, biology and other fields.Recently, a team of astronomers used Summit to simulate a supermassive black hole and the swirl of matter (the “accretion disk”) that surrounds it ...read more
Unique conditions appear to have preserved part of an ancient wooden structure dating back at least 476,000 years. This time was well before the presumed evolution of modern humans, upsetting old notions of hominid development.No one knows what the structure was, only that it appears to have been fashioned with stone tools to fit together in an interlinking fashion similar to Lincoln Logs. The scientific team led by archaeologist Larry Barham found a single such connection composed of a longer, ...read more
