A preserved tusk revealed how far the animal ranged during its 28-year lifetime. A mammoth that lived in Alaska about 17,000 years ago traveled so far and wide that, if it had walked in a straight line, it would have gone all the way around the world — nearly twice.Continue Reading

An ocean-powered buoy brings technology closer to the dream of obtaining energy from the sea One key to harvesting the ocean’s clean energy—at least a little of it—may lie in static electricity. A team of researchers in Portugal has now successfully used it to run small generators inside a navigationalContinue Reading

New simulations show one way the voids might lose their ‘hair’ Like a shaggy dog in springtime, some black holes have to shed. New computer simulations reveal how black holes might discard their magnetic fields. Unlike dogs with their varied fur coats, isolated black holes are mostly identical. They areContinue Reading
