    • 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.
