Hot Topic Origins Extreme Life
Searching for Alien Life, on Earth
Topic: Extreme Life
Summary: Mono Lake, just east of Yosemite National Park, is a place of bizarre natural beauty. It also boasts one of the highest natural concentrations of arsenic on Earth. The latter fact, says geomicrobiologist Felisa Wolfe-Simon, makes it a good spot to look for alien life.

Fun Science: Iceberg Chasing and Laser Lights
Topic: Extreme Life
Summary: During the 2009 AMASE Expedition to Svalbard, scientists were able to carry out 'fun science' activities in addition to their normal research schedule. In this report, team member Juan Diego Rodriguez-Blanco discusses projects like 'iceberg chasing' and developing Raman spectroscopy for Mars.

Adding Up the Odds for Life
Topic: Extreme Life
Summary: Researchers are laying the groundwork for a new equation that could mathematically quantify whether or not a particular environment is habitable for life as we know it. The concept is based on the Drake equation, which was developed for estimating the number of extraterrestrial civilizations in our galaxy.

Roving the Ocean Floor
Topic: Extreme Life
Summary: A rover that has been driving across the ocean floor off the California coast is providing researchers with an entirely new view of life in the deep ocean. The Benthic Rover is exploring the unique habitats deep below the Pacific waters and is also helping document the effects of climate change on these fragile environments.

Subtracting Sulfur
Topic: Extreme Life
Summary: Microbes from the ocean have been shown to process methane in ways that were previously unknown. The discovery could help astrobiologists understand how the early biosphere of Earth interacted with our planet's atmosphere.

Wanted: Easy-Going Martian Roommates
Topic: Extreme Life
Summary: Mars is not for the finicky. If something does live there, it's likely going to be similar to the more adaptive life forms on our planet. A group of researchers is studying a particular microbe that they think could be a model for Mars life.

Coaxing Cold Colonies Back to Life
Topic: Extreme Life
Summary: A bacterium recovered from beneath three kilometers of glacial ice in Greenland may hold clues as to how life could exist on other planets. Astrobiologists are now studying the unique organism, which has been isolated under ice for over 120,000 years.

Topic: Extreme Life
Summary: A team of researchers at the Monterey Bay Aquarium Research Institute conducted the first field test earlier this year of a new configuration of Deep-ESP. The device is designed to perform long-term studies of how deep-sea ecosystems respond to environmental changes.

Erupting with Life
Topic: Extreme Life
Summary: Scientists have been studying a unique undersea volcano that appears to be continuously active and supports unique biological communities. The site, dubbed NW Rota-1, is located near the Island of Guam and is helping astrobiologist understand how life can thrive under extreme conditions in the depths of the oceans.

Outer Space Oreos
Topic: Extreme Life
Summary: Scientists have previously exposed organisms and biomolecules to the many rigors of space, but those experiments only managed to take "before" and "after" pictures of their samples. A planned small satellite will monitor on a continuous basis the negative effects of space on biology.
