Ursus maritimus is the scientific name for polar bears, named in 1774 by Constantine Phipps. Polar bears are marine mammals in the Ursidae family, adapted to Arctic sea ice. Polar bears don't truly ...

A Polar vortex has covered the Philadelphia region under a canopy of frigid temperatures, but many people may not realize what a Polar vortex actually is, and the dangers — like frostbite — such ...

Multiple states registered subzero temps on Friday, Dec. 5. The polar vortex has broken, and severe temperatures are dominating even in southern sates like Texas, which saw record breaking lows in the ...

Meet our story’s protagonist: a female polar bear. Displaced by shrinking sea ice in the Arctic, she was forced to wander south, deeper into the Canadian Northwest Territories. Here, our lady in white ...

Polar bears in one of the fastest-warming parts of the Arctic are showing clear changes in how their DNA behaves, according to a new study. Researchers examined genetic activity in polar bears from ...

This study was funded by grants from the Natural Environment Research Council (NE/S011188/1) and the European Research Council (SELECTHAPLOID - 101001341) The Arctic Ocean current is at its warmest in ...

The world’s polar bear population is projected to decline by two-thirds by 2050. A new study from the University of East Anglia suggests that polar bears are undergoing rapid genetic changes, and ...

Grab your coats, it's getting chilly. A polar vortex broke, and severe temperatures are set to dominate most of the United States, including the Midwest, in the coming days. The polar vortex will ...

The wall that keeps cold air contained in the Arctic is called the polar vortex. There's been a "displacement" in the polar vortex, which allows Arctic air to escape to the south. An "arctic frontal ...

With climate change steadily dismantling the icy habitat essential to their existence, new research suggests polar bears are rapidly rewiring their own genetics in a bid to survive. The species is ...

Warming temperatures appear to be driving genetic mutations in some polar bears to help them survive the shifting climatic conditions. When you purchase through links on our site, we may earn an ...
