Polar bears are running out of ice and out of time, yet inside their cells something remarkable is happening. As the Arctic warms and traditional hunting grounds vanish, researchers are finding that polar bear DNA is shifting in ways that look like a last ...

Researchers have recently discovered something astonishing. Not only have there been changes in polar bears’ DNA, but it appears to have a direct correlation with where they live. Specifically, polar bears in warmer climates seem to have developed adapted DNA in a somewhat new survival mechanism to deal with our heating planet.

Researchers have found that certain changes in polar bear DNA are linked to bears living in warmer places — with implications for how the animals adapt to a warming planet. A recent study published in the journal Mobile DNA found distinctive shifts in the genes and gene expressions of polar bears living in warmer areas.

Polar bears are leaping through their evolution in real time as rising temperatures threaten their habitat. A population of bears was found in a climate warmer than one in which they usually exist, showing genetic differences from their colder-weather ...

In fact, polar bears do not actually have white fur. No, we aren’t kidding. These fluffy mammals, which survive in the icy Arctic, are actually born with black skin. Their fur is hollow and transparent,

Kallik, a 3-year-old polar bear from the Saint Louis Zoo, is making a splash at the Oregon Zoo’s Polar Passage habitat. He explored his new habitat for the first time
