Elucidation of molecular mechanisms underlying anhydrobiosis:
Water is an essential element of life. Even though most organisms will die when subjected to a severe depletion of water, there are some that can survive. Simple rehydration allows these dehydrated organisms to resume active life. The sleeping chironomid is the only insect with this anhydrobiosis capability, which is a state of suspended animation by desiccation. The desiccated larvae can tolerate a variety of stresses. Eventually, the larvae can be revived, even after exposure in outer space for over two years.
