Students build submarine to track Octopuses
... Vincent said. "Then there will be a wireless link between
the buoy and the boat." The team also will modify Shadow's buoyancy system. Water flows into a ballast ring that circles the center of the sub. The amount of water that it takes on determines the sub's buoyancy, allowing it to submerge to any depth. ...

an organism's genes and the outside world. One project will examine how a plant evaluates the various cues of seasonal change so that it blooms when it has the best chance to reproduce successfully. A second project will try to unravel "ecological ge...

a pleasurable response to sweet taste (sweet liking) and a genetic vulnerability to alcoholism among children of alcoholic fathers. Sweet liking, however, is insufficient by itself to predict alcoholism. New findings published in the September issu...
