Hot Topic Origins Extreme Life
 
The Lessons of Exposure
Topic: Extreme Life
02/06/06
Summary: In this interview with Gerda Horneck, she shares her concerns about sending humans to Mars. She also explains why our own bacteria, after being exposed to the harsh radiation of outer space, won´t come back to haunt us.

Multitasking Microbes
Topic: Extreme Life
02/05/06
Summary: Scientists have found that photosynthetic bacteria living in scalding hot springs have two radically different metabolic identities. The study sheds new light on the metabolic mechanisms that living cells use to survive in harsh environments.

Crater Diary, Part I
Topic: Extreme Life
01/09/06
Summary: Travel with Aaron Gronstal on a drilling expedition in Chesapeake Bay, the site of a 35 million-year-old impact crater. This portion of his journal is part 1 of a 4-part series.

Poquentica
Topic: Extreme Life
01/02/06
Summary: Some of the highest lakes in the world can be found at the summits of volcanic mountains in the Andes, straddling the border between Chile and Bolivia. The High Lakes 2005 research team has just completed an expedition to explore two of those lakes. The lakes offer researchers an opportunity to study life in an extreme environment on Earth that in many ways mimic conditions on Mars. Expedition leader, Nathalie Cabrol, concludes her series of captain's logs.

Columbia Survivors
Topic: Extreme Life
01/01/06
Summary: On the Space Shuttle Columbia mission STS-107, researchers were studying the nematode worm Caenorhabditis elegans. The mission ended in tragedy when the shuttle broke up during reentry. Remarkably, the worms, housed in specially designed canisters, survived the virtually unprotected reentry into the Earth's atmosphere.

Patience with the Mountain
Topic: Extreme Life
12/19/05
Summary: If you're looking for the world's tallest mountains, head for the Himalayas. But if your objective is to explore the world's highest-altitude lakes, the Andes are where you want to go. The tiny lake inside Licancabur's summit crater presents some of the harshest conditions faced by life anywhere on Earth. Astrobiology Magazine is posting a series of log entries from the expedition leader, Nathalie Cabrol. She wrote down her reflections just after the High Lakes 2005 team managed to reach Licancabur's summit lake.

Licancabur Ascent
Topic: Extreme Life
12/15/05
Summary: Scientists have traveled into the Bolivian Andes to study the life forms - mostly microbes - that inhabit some of the highest lakes in the world. These lakes offer an opportunity to study life in an extreme environment on Earth that is in some ways like conditions on Mars.

Swarming for Success
Topic: Extreme Life
12/12/05
Summary: Dr. Penelope Boston and Dr. Steven Dubowsky are working to develop "hopping microbots" capable of exploring hazardous terrain, including underground caves. If the project pans out, hopping microbots may some day be sent to search for life below the surface of Mars. In Part II of this interview, Dr. Boston talks about the swarm-like behavior of large groups of microbots that enables them to perform sophisticated research tasks.

Exploring Caves with Hopping Microbots
Topic: Extreme Life
12/08/05
Summary: For the past several years, NASA has been encouraging scientists and engineers to think outside the box, to come up with ideas just this side of science fiction. One of the projects that received funding earlier this year was a collaboration between Dr. Penelope Boston and Dr. Steven Dubowsky to develop "hopping microbots" capable of exploring hazardous terrain, including underground caves.
