Hawaiian Whales Show 'No Overt Response' To Sounds Of ATOC Simulation
...ered 150-10,000 kilometers away. Because sound travels
faster in warmer water, shorter travel times would indicate that the oceans are warming. The $5.7-million Marine Mammal Research Program is headed by Christopher W. Clark, director of the Cornell Bioacoustics Research Program. The Hawaiian ATOC ...
Changing Continental Runoff Patterns Could Change Ocean Circulation
...n traveling toward the equator, while warmer water travels
poleward near the surface. Temperature, not salinity, seems to control ocean circulation today. One reason why the researchers are looking at the early Eocene is that it was the most recent warm period in the Earth's history. Researchers beli...

Learning To Feel Chronic Pain
...internal organs trigger an electrical impulse that travels
along a nerve fiberto the dorsal horn of the spinal cord. That fiber connects with a nerve cell,which passes the pain signal up the spinal cord to the brain. Because thesignals cross junctions -- synapses -- on their way to the brain, they can bemodi...
Birds Of A Feather: The Physics Of Flocks

from neighbor to neighbor until it is transmitted throughthe entire material. But like an ink drop spreading through a cup of water,diffusion is slow and the errors are more burdensome as they are shared by fewerbirds. In the bird flocking model, i...
Researchers Grow Healthy Human Placental Cells For Drug Research
