Hot Topic Origins Extreme Life
Living on the Red Edge
Topic: Extreme Life
Summary: Researchers have sequenced the genome of a unique bacterium that uses a rare form of chlorophyll to harvest far-red light. It is the first chlorophyll-d containing organism to be sequenced, and will provide new information about the genetic evolution of life on Earth.

Liquid Locked in Ice
Topic: Extreme Life
Summary: A team of scientists has begun exploring an ancient lake hidden 3.2 km beneath Antarctica's ice sheet. Lake Ellsworth could harbor unique microbial life and might provide clues about climate change on Earth.

Astrobiology Top 10: When Fungi Ruled the World
Topic: Extreme Life
Summary: Astrobiology Magazine is looking back over 2007, highlighting the Top 10 astrobiology stories of the year. At number 6 is the discovery that 420 million years ago, fungi stood as tall as trees, reaching up to 20 feet in height.

Astrobiology Top 10: Brought Back to Life
Topic: Extreme Life
Summary: Astrobiology Magazine is looking back over 2007, highlighting the Top 10 astrobiology stories of the year. At number 8 is the recovery of DNA from ancient microorganisms. The DNA showed an "exponential decline" after 1.1 million years, indicating how long DNA could be preserved in rocks in cold places.

Life at Hell's Gate
Topic: Extreme Life
Summary: A new species of bacteria has been discovered in a geothermal field in New Zealand known as 'Hell's Gate'. The bacteria is the hardiest 'methanotrophic' bacteria yet discovered, and may help in the fight against global warming.

Leaving No Stone Unturned
Topic: Extreme Life
Summary: Kimberley Warren-Rhodes has spent countless hours in some of the world´s driest deserts, turning over rocks. Tens of thousands of rocks. What is she hoping to find? The pattern of life.

Living Time Capsules
Topic: Extreme Life
Summary: Researchers have thawed ice from Antarctica that is at least a million years old to search for eons-old microorganisms. The microbes may have survived in total darkness, freezing cold and without food or energy from the Sun.

Jumping Viruses
Topic: Extreme Life
Summary: A new study in the hot pools of Yellowstone shows that microbial viruses may be traveling from pool to pool along with steam. The research on these extreme habitats for unique life may shed light on how microbes, and the viruses that infect them, impact their environment.

Deep Drilling for
Topic: Extreme Life
Summary: Researchers are preparing for a deep-drilling project in Iceland where they will study the processes in deep, hot rocks below the terrestrial surface. Through the study, they also hope to learn more about 'black smoker' hydrothermal vents in the ocean, which are known to support some of Earth's most unique organisms.

Life's Hot Spot
Topic: Extreme Life
Summary: Thousands of new kinds of microbes have been discovered living around hydrothermal vents off the Oregon coast. The new study has also yielded clues about how deep-sea microbial communities are connected to the global climate of Earth.
