• Researchers Generally Happy With Final Stem Cell Rules

    The final guidelines on research with human embryonic stem cells issued on Monday by the National Institutes of Health set out criteria for determining which ES cell lines can be used in federally funded experiments and give NIH discretion to approve old lines that don't meet stringent modern ethical requirements.

  • From Science's Online Daily News Site

    Highlights from Science's online daily news site, ScienceNOW, this week include a criminal investigation tool that can be used to track sharks, atoms speeding from the moon, a fish that throws away its genes as it grows, and a yawn from the napping sun.

  • Back to the Drawing Board for Psychiatric Genetics

    In 2003, researchers reported that a gene variant seemed to play a major role in whether people get depressed in response to life's stresses or sail through. But an exhaustive new analysis published last week in The Journal of the American Medical Association suggests that the big fish may be a minnow at best.

  • The Promise of a Cure: 20 Years and Counting

    The discovery of the cystic fibrosis gene brought big hopes for gene-based medicine; although a lot has been achieved over 2 decades, the payoff remains just around the corner.

  • Water Flea Boasts Whopper Gene Count

    Daphnia pulex, a crustacean common in lakes and ponds around the world, is no bigger than the letters on this page, but its genome contains more genes than some much larger organisms have, scientists reported at the Biology of Genomes meeting.

  • The Bug and the Bacterium: Interdependent Genomes

    The newly sequenced DNA of the pea aphid, a common pest of legume crops, reflects a long history of give-and-take between the genomes of the bug and a tiny bacterium called Buchnera aphidicola, scientists reported at the Biology of Genomes meeting.
