Indestructible 'water bear' bug that can survive in space could revolutionise computing. 1  Animals are able to dry them selves out for years - and come back to life. 2  Protect themselves in large amounts of glassy molecules. 3  Researchers hope to harness molecules to create 'superglass'.
Polar bears have been known to live for 20 years or more, although few live longer than their late teens. The oldest wild polar bear was 32 years old, and the oldest polar bear in a zoo was 41 years old. Researchers can find out how old a polar bear is by removing a tooth. Each year, a bear's teeth grow a little larger. The end of the tooth is cut off and there is a ring for each year, just like on trees. The researchers simply count the rings to find out how old polar bears are. 5 rings means a polar bear is five years old.
