Tardigrades are the undisputed masters of survival. Bake them at 300 degrees Fahrenheit, freeze them to within a degree of absolute zero, deprive them of water and oxygen, subject them to the vacuum of space — they will still survive. And now scientists have begun to show how we can harness their legendary resilience to advance human medicine. Inspired by the feats of these near-microscopic animals (also known as water bears), researchers at the University of Wyoming wanted to see what would h ...read more

The myth of Rasputin, the Mad Monk, is well-known: He was a scheming sexual predator who insinuated himself into court life with devastating effects on Russia’s royal family. The reality — what we know of it — is much more nuanced.
