  • The Ecoresponsive Genome of Daphnia pulex

    The Daphnia genome reveals a multitude of genes and shows adaptation through gene family expansions.

  • Metagenomic Discovery of Biomass-Degrading Genes and Genomes from Cow Rumen

    Metagenomic sequencing of biomass-degrading microbes from cow rumen reveals new carbohydrate-active enzymes.

  • 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.
