Brain chemistry ties anxiety and alcoholism
Doctors may one day be able to control alcohol addiction by manipulating the molecular events in the brain that underlie anxiety associated with alcohol withdrawal, researchers at the University of Illinois at Chicago College of Medicine and the Jesse Brown VA Medical Center report in the March 5 issue of the Journal of Neuroscience.

Why juniper trees can live on less water
An ability to avoid the plant equivalent of vapor lock and a favorable evolutionary history may explain the unusual drought resistance of junipers, some varieties of which are now spreading rapidly in water-starved regions of the western United States, a Duke University study has found.

Oncoproteins double-team and destroy vital tumor-suppressor
wo previously unconnected cancer-promoting proteins team up to ambush a critical tumor suppressor by evicting it from the cell's nucleus and then marking it for death by a protein-shredding mechanism, a team led by scientists at The University of Texas M. D. Anderson Cancer Center reports in the Feb. 10 issue of Nature Cell Biology.

New Rendering Of Ion Channel Suggests How Neurons Fire
Four years ago, Roderick MacKinnon, head of the Laboratory of Molecular Neurobiology and Biophysics at Rockefeller University, together with several members of his lab, published the first ever structure of a voltage-dependent potassium ion channel — a protein that controls the flow of potassium ions across nerve cell membranes and opens and closes in response to changes in cell membrane voltage.

Evolutionary battle scars' identify enhanced antiviral activity

New Model Of Competitive Speciation Unifies Insights From Earlier Work
Under which circumstances is sympatric speciation possible? An answer to this long-standing question of evolutionary biology has turned out to be challenging. In particular, models for the evolution of assortative mating under frequency-dependent disruptive selection necessarily depend on a large number of ecological and genetic factors.

One Small Step for Plants
The first analysis of a moss genome reveals that mosses are surprisingly complex, with 35,000 potential genes--10,000 more than the first land plant sequenced--and a host of unique adaptations not found in other green landlubbers. And because of where mosses fall on the plant family tree, those genes are revealing how plants made their way onto land.
