Ice worms are able to boost their cells' energy production when the temperature drops. They also have cell membranes and enzymes that function and stay flexible in temperatures where most animals' cellular processes come to a halt. The downside is extreme sensitivity to heat. At about 40°F, the worms' membranes melt and their enzymes cease to function.
In 2005, NASA provided $200,000 to fund research to explore the worms' cold tolerance and what it might say about the possibility of life on Jupiter's icy moons and other planets. The results of such work might also help improve cold storage of organs and tissues for transplantation.
