Scientists sequence genome of kind of organism central to biosphere's carbon cycle
...lobal warming. "Now that we have a glimpse at the inner
workings of diatoms, we're better positioned to understand how changes in the environment will translate into increases or decreases in diatom abundance," says Dan Rokhsar, who heads computational genomics at the Joint Genome Institute and one of the...

'Fossil genes' reveal how life sheds form and function
...to the demands of its environment, has changed its inner
chemistry and lost the ability to metabolize a key sugar. The finding is a snapshot of evolution at work showing, at the most fundamental level, how traits and features are discarded by virtually all forms of life when they are no longer needed. "Man...
