Go to the world's highest lake, to dive into an ancient volcano, presents new challenges for expedition leaders from NASA and the SETI Institute. Their interest is piqued by the prospects of monitoring microbes that survive in the low oxygen, high ultraviolet lakebed.

Finding Nemo 10: Weird Adaptations
Topic: Extreme Life
