This radio show describes the tenacious life of some specialized microbes, featuring an interview with scientist Mitchell Sogin. The interview highlights the ability of microbes to evolve and adapt to extreme environments on Earth. The Sogin Research Lab explores the limits of the envelope where microbes can grow by looking for life around hydrothermal vents at the bottom of the ocean. They are studying the cellular mechanisms allowing microbes to withstand such extreme conditions by investigating the genetic differences in these organisms. The web site includes a transcript for the show, and an audio clip of the interview. It also provides a link to more information about extremophiles- particularly eukaryotes of the Rio Tinto. RealPlayer software is needed to play the audio clip and can be downloaded for free at http://www.real.com. The clip lasts 1 minute, 33 seconds.
