The Arctic Ocean is generally considered a remarkably quiet ocean, with very little mixing, because a cover of sea ice prevents wind from driving the formation of internal waves. To study this effect and investigate how melting sea ice might affect ocean mixing in the Arctic, researchers analyzed data from moorings in the northern Chukchi [...]

Even the way people remember dance moves depends on the culture they come from, according to a new article. Whereas a German or other Westerner might think in terms of “step to the right, step to the left,” a nomadic hunter-gatherer from Namibia might think something more like “step to the east, step to the [...]

In trying to explain psychiatric disorders, genes simply cannot tell the whole story. The real answers are in the interaction of genes and the environment. Post-traumatic stress disorder requires some trauma, for instance, and people, for the most part, aren’t born depressed. Now research has revealed one mechanism by which a stressful experience changes the [...]

Two independent teams of researchers have identified a role for enhanced activation of the signaling protein Notch in tumors characterized by inactivation of either the TSC1 or the TSC2 protein. These data provide a rationale for testing whether Notch inhibitors are of benefit to those with TSC-associated tumors.

Researchers have new insight into the sex lives of the much-maligned mosquitoes that are responsible for the vast majority of malaria deaths, according to a new study. In finding a partner of the right species type, male and female mosquitoes depend on their ability to “sing” in perfect harmony. Those tones are produced and varied [...]
