Glacial Ice Worm Seminar
Fantastic psychrophilic beasts and which glacier to find them.
Glacial ice worms are little known creatures as they only can live in glaciers. They are the largest multicellular eukaryotes that require freezing temperatures to survive. They are like their “down-to earth” cousins, the earthworms. But they have an extremely exotic adaptation to a low temperature environment. For example, their membrane has such as a low melting point (to prevent being frozen at low temperature) that the ice worm can be reduced to a pool of water at room temperature. To survive in such a harsh environment (little food and cold), many adaptions are being made at the biochemical level. Studying these eukaryotic extremophiles has impact in many scientific fields, from cryopreservation, life origin, geobiology, environmental sciences, to genetics, biochemistry, and medicine.
Professor Daniel Shain (Rutgers U.) is an expert studying extremophile, especially those in cold environments, from rotifers to ice worms. He will give a talk (titled “The Ice Worm Cometh”) on how he searches for these exotic creatures in glaciers and studies their genetics, biophysics, and biochemistry. This seminar is open to the public and supported by the Haines Morris fund and the Department of BCMB at UT. Specifically, Dr. Shain focuses on the bioenergy aspect of ice worm and the ATPase biochemistry (how they regulate energy consumption).
