Ordinarily, polar and nonpolar molecules don't mix. Polar compounds, such as water and hydrogen cyanide, have an uneven distribution of charge across the molecule, creating some areas that are ...

A research group at The University of Tokyo has discovered a new principle by which helical chiral molecules acquire spin ...

A remote Arctic island once used as a Soviet weather station has become overrun by polar bears. On Kolyuchin Island, in Russia’s Chukchi Sea, dozens of bears now roam through abandoned buildings and ...

Climate change is transforming ecosystems in the far north. An international team of scientists has made some surprising discoveries. Ashild Onvik Pedersen, a scientist who is armed with a rifle in ...

In a violent Arctic game of tug-of-war, several polar bears in northern Canada had to fend off an overly eager—and outnumbered—black bear vying for a meal. And the entire ordeal was captured on video.

Oct. 6 (UPI) --Sir Ernest Shackleton's polar ship, Endurance, was considered to be the strongest of its time but the vessel had significant structural weaknesses that caused its demise -- and an ...

Researchers in McGill's Department of Physics have developed a new device that can trap and study DNA molecules without touching or damaging them. The device, which uses carefully tuned electric ...

The polar vortex is a large region of low pressure and cold air that has always existed around Earth's poles. While the polar vortex is weakening for the season, it does not directly cause winter ...

The south pole of Enceladus—a tiny moon orbiting Saturn—is a volatile place. In this region, the moon’s subsurface ocean spews jets of water through four “tiger stripe” cracks in the icy crust, ...

The polar vortex is stirring up, bringing the earliest hints that the weather is changing as autumn has officially arrived. In the short term, this means gradual cool-downs and a more active storm ...

The Earth's polar vortex is stirring up, bringing the first hints at changing weather as fall descends on the U.S. This movement means gradual cooling and a more active storm track across the northern ...
