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'.
The daily amount of energy needed to sustain a 440-pound polar bear is equal to the energy value of about two pounds of seal blubber. In winter, polar bears also live off fat, but it is seal fat rather than their own body reserves.âIf a polar bear were to eat a lot of protein when it is â50 or â60 degrees Fahrenheit,â says polar bear expert Dr. Jonkel, âthen they would need a lot of water in order to get rid of the nitrogen wastes.his is the polar bearâs habitat. Although footprints of wandering polar bears have been seen within two degrees of the North Pole, this is uncommon, since few seals or other animals live this far north. The distribution of polar bears and seals is influenced by the continuous patterns of ice freezing and breaking up.
