  • 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

  • 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.
