  • The Species Problem

    Our ancestors are now thought to have mated with at least two kinds of archaic humans at two different times and places. Were they engaging in interspecies sex, or does the fact that they were able to produce offspring mean they were all members of the same species?

  • Telling Time Without Turning On Genes

    Researchers have now found evidence—in people and in algae—for a eukaryotic circadian clock that works independently of gene activity. This protein-based timekeeper might represent an evolutionarily ancient way of keeping cellular time.

  • From Science's Online Daily News Site

    ScienceNOW reported recently that young mollusks maturing in slightly warmer and more acidic seawater can't calcify their shells, the "placebo effect" may work even if patients know they are taking fake pills, people rely on the eyes to judge whether a face has a mind behind it, and DNA from an ancient finger bone has confirmed the discovery of a new type of human, among other stories.

  • Integrative Analysis of the Caenorhabditis elegans Genome by the modENCODE Project

    Extensive analysis of the Caenorhabditis elegans genome reveals regions highly occupied by multiple transcription factors.

  • Identification of Functional Elements and Regulatory Circuits by Drosophila modENCODE

    The Drosophila modENCODE project demonstrates the functional regulatory network of flies.
