When you get infected with a virus, some of the first weapons your body deploys to fight it were passed down to us from our microbial ancestors billions of years ago. According to new research from ...

Antarctic dwelling single-celled microorganisms called archaea can behave like parasites, new research shows. In Antarctica is a small lake, called Deep Lake, that is so salty it remains ice-free all ...
