  • Predator, Prey, Parasite
    Scientists have discovered that parasites are surprisingly important in food webs. According to a new study in the Proceedings of the National Academy of Sciences, parasites may be the thread that holds the structure of ecological communities together.

  • Jellyfish-Like Creatures Fight Global Warming
    Transparent jellyfish-like creatures known as salps, considered by many a low member in the ocean food web, may be more important to the fate of the greenhouse gas carbon dioxide in the ocean than previously thought.

  • The Oxygen Imperative
    It's common knowledge that humans and other animals couldn't survive without oxygen. But scientists are now learning a good deal more about the extent of our evolutionary debt to a substance that was once a deadly poison.

  • Sequencing the Seas
    Scientists have sequenced and compared the genomes of planktonic microbes living throughout the water column in the Pacific Ocean. The pioneering study yielded insight into the specialization of microbial communities at each depth--ranging from 40 to more than 13,000 feet.

  • Eyes in the Ocean
    Scientists at Oregon State University have successfully cultured in a laboratory a microorganism with a gene for an alternate form of photochemistry an advance that may ultimately help shed light on the ecology of the world's oceans.

  • Did Earth Have Purple Oceans?
    NASA exobiology researchers confirmed Earth's oceans were once rich in sulfides that would prevent advanced life forms, such as fish and mammals, from thriving. The research was funded in part by NASA's exobiology program.
