Hot Topic Origins Extreme Life
Sunken Logs Create New Worlds for Seafloor Animals
Topic: Extreme Life
Summary: A new paper shows that wood-boring clams serve as "ecosystem engineers," making the organic matter in the wood available to other animals that colonize wood falls in the deep waters of Monterey Canyon.

Mars Exploration in a Deep Mine
Topic: Extreme Life
Summary: Scientists are testing technologies for Mars exploration in a 1.3 kilometer-deep mine. The project is part of the Mars Analogues for Space Exploration (MASE) program.

Antarctic Moss Lives After 1,500+ Years Under Ice
Topic: Extreme Life
Summary: Researchers report that Antarctic mosses can come back to life after 1,500 completely inactive years under the ice. Prior to this finding, only microbes had been shown to be capable of revival after so many years on hold.

Surviving Below Freezing
Topic: Extreme Life
Summary: Scientists have documented how a leech is able to survive cycles of freezing and thawing, and temperatures as low as -196°C.

Microbes, How Low Can You Go?
Topic: Extreme Life
Summary: It seems like anywhere you look on Earth, microorganisms are there - even kilometers beneath the Earth's surface where sunlight never reaches. Scientists are just beginning to understand Earth's deep subsurface biosphere, but a new study might help determine just how far down microbes can go on our planet. The results could also shed light on the potential for life's origins in the deep, dark Earth.

A Protein for Photosynthesis in Ancient Microorganisms
Topic: Extreme Life
Summary: Scientists have discovered that a protein used in photosynthesis in plants likely developed in microorganisms on ancient Earth - long before oxygen became availalbe in the atmosphere.

New Species of Sea Anemone Found in Antarctic Ice
Topic: Extreme Life
Summary: In 2010, a team of scientists discovered a new species of sea anemones beneath Antarctica's Ross Ice Shelf. The new anemones are the first known to live in ice.

Predatory Organisms at Depth
Topic: Extreme Life
Summary: A new study shows that viruses might greatly outnumber microorganisms in the deep biosphere of the Earth.

Poison-Breathing Bacteria
Topic: Extreme Life
Summary: Researchers have discovered bacteria in California's Mono Lake that 'breathe' toxic metals.

Beating Bacteria on Earth -- and in Space
Topic: Extreme Life
Summary: Already a major problem on Earth, increasingly resistant bacterial strains can be an even greater threat for space travelers. The Antibiotic Effectiveness in Space (AES-1) investigation will attempt to probe the reasons for antibiotic resistance in space.
