Polar bears typically depend on solid sea ice to hunt and keep their bellies full. To breathe, seals pop up in holes in the frozen seawater, and there the bears ambush and eat them. Now, however, scientists have discovered a group of polar bears in southeastern Greenland that does things differently, using a slushy mix of freshwater snow and ice as a platform to ambush seals. This new population may offer clues to how polar bears will fare as the Arctic warms at an alarming rate and sea ice shrinks, threatening many polar bears with starvation.
