  • Life’s  Limit
    Extreme life forms can thrive in harsh conditions of salt, pressure, temperature and pH, but share a common theme of needing liquid water. Dr. Rocco Mancinelli of the SETI Institute describes his fascination with finding what are the environmental limits to life.

  • Biology’s Theme Park: RNA World
    When a laboratory recipe for life starts to look daunting, scientists have retreated to a test-tube for what they term 're-evolving evolution'. Their model is one of the template molecules for life, the counterpart to DNA itself, called RNA, which replicates a pattern for cell

  • Alien Infection
    As we look toward exploring other worlds, and perhaps even bringing samples back to Earth for testing, astrobiologists have to wonder: could there be alien pathogens in those samples that will wreak havoc on our world?

  • Dune and Salt Hybrids
    Creating hybrids with cross-species breeding has long been used for corn production. But for most attempts, sterile offspring are generated. A new Indiana University study shows that for desert and salt-adapted sunflowers, rapid evolution can be induced from such cross-breeding experiments.

  • World’s Smallest Power Station
    Turning light into power fuels the biosphere, in a cycle that begins with the lowest part of the foodchain, the microbes. Three international teams have put together a plan to understand genetically how all that light gets harvested.

  • Life from the Heavens?
    The scientific community has been impressed with the robustness of environments that can support life, ranging from Antarctic lakes to salt mines to nuclear reactors. But conventional wisdom has presumed that life traveling to Earth on a fiery meteor--if possible--would meet a quick sterilizing death.

  • Gene Menagerie
    A pioneering study comparing the genes of 13 species has uncovered clues to how the vertebrate family tree might have evolved. One intriguing result is that primates, including humans, are closer to rodents than carnivores or cows and pigs.

  • The Unboilable Bug
    Long thought to be impossible, a single-celled microbe has been found to thrive above the boiling temperature of water. The record-holder, called 'Strain 121', is part of a class of extreme lifeforms, but surviving a top temperature of 250 degrees Fahrenheit takes this discovery into

  • Spying on Biodiversity
    Monitoring of species which may have natural habitats in remote areas is no easy task. Using internet cameras, a group of Alaska biologists can keep warm, while watching the great outdoors.

  • Atlantis Diary XI: Encore
    Diving near the North Atlantic ridge, a team of 24 scientists have begun exploring the deep, hot vents where the Earth's inner mantle meets the crust. Their spectacular world --discovered just two years ago--will be chronicled in their online journal account, the Atlantis Diaries.
