A team of marine biologists affiliated with multiple institutions in Italy has found that some marine worms are able to survive in cold polar waters thanks to symbiotic bacteria that produce antifreeze-like proteins.
One of the last big unknowns in the global climate equation is Antarctica. How stable is the Antarctic ice sheet? More than a mile thick, on average, it locks up 70 percent of the Earth's fresh water.
