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'.
Living in the Arctic, the polar bear faces many challenges. One of the many challenges is a shrinking habitat. We humans have greatly contributed to the shrinking of the sea ice, which makes finding food harder for the polar bears. In a way, polar bears face loss of habitat space and food. There are not many animals that will feast on the polar bears, so they have no need to fear predators. As we humans slowly encroach on the polar bear habitat, we also pollut parts of their environment. Information and Media Sources: Survival Adaptations: Polar bears are normally very solitary, and that can help them avoid fighting each other. In certain scenarios, the polar bear would rather escape than fight. As young cubs, polar bears play-fight. Play-fighting while they're young helps them prepare for competition during mating season.
