The Ends of the Earth
|
| Topic: Extreme Life |
08/18/05 |
| Summary: On June 16, 2005, Pamela Conrad gave a lecture entitled, "A Bipolar Year: What We Can Learn About Looking for Life on Other Planets by Working in Cold Deserts." In part 1 of this edited transcript, Conrad describes what sort of signs we could look for to see if there is life in an alien environment. |

Living in the Dead Sea
|
| Topic: Extreme Life |
07/17/05 |
| Summary: How have the molecules essential to life, such as proteins, adapted to function in extreme environments? The proteins that may help answer this question have been isolated from halophilic (salt-loving) microorganisms from the Dead Sea. So what's living in the Dead Sea anyway? |
