Extreme Life

  • Life Down Under
    Recent work by Christopher Chyba (SETI Institute) and Kevin Hand (Stanford University) suggests that there may be ways to nourish biology in watery environments where the Sun's rays don't penetrate.

  • How Small Can Life Be?
    As advanced microscopes enable us to peer deeper into the realms of inner space, biologists have been faced with a vexing question: Is there a size limit on life?

  • Raising Baby Tubeworms
    For years scientists have wondered how giant red-tipped tubeworms and other exotic marine life found at hydrothermal vents get from place to place and how long their larva survive in a cold, eternally dark place. Now biologist Lauren Mullineaux and colleagues have helped answer

  • Pyruving the Origin of Life
    For the origin of life, chemical synthesis of pyruvic acid is a critical step. In a difficult experiment, Carnegie Institute/NAI researchers report that the natural synthesis of such compounds would occur wherever hot ocean vents pass through iron sulfide-containing crust.
