UCSF study finds danger in marathon runners drinking too much water
... the brain. The brain responds to the pressure by sending an emergency distress call to release water into the lungs. The lung fluid, or the brain pressure, eventually kills most patients with hyponatremia, Arieff said. "They either suffocate or their brain herniates," he said.

...ike any good housekeeper, sweeping up the dirt and sending it to a landfill keeps the house tidy and clean. Researchers interested in tidying up the earth's atmosphere are devising ways to sweep up excess carbon dioxide -- a potentially problematic greenhouse gas -- and store it out of harm's way.

...ar for the last 13 years," she said. "Penguins are sending a signal that climate change is here. The irony is that cold years are saving the population. Even though breeding success will be low this year, the survival of last year's young will be high and that means in three to five years these young will be...Stowaways from space provide link between impact, biggest extinction in Earth history

The coupling of a massive impact and widespread volcanic activity also occurred in the more widely publicized extinction event that wiped out the dinosaurs 65 million years ago, at the K/T (Cretaceous/Tertiary) boun...Elephants pick up good vibrations - through their feet

The behavior prevents pioneering nerves from backtracking and laying down faulty wiring that could spell disability or death to the embryo. The discovery of how axons can simply "walk away" from an attractant is reported in the March...Faster nanowires may advance nanotechnological applications for detecting glucose, hormones or DNA

But such applications are far from reality yet because handling nanowires is not at all like handling ordinary electrical wires. T...Scientists, ships, aircraft to profile Asian pollution and dust

... Vasopressin is a neurotransmitter responsible for sending certain signals within the brain. The gene transfer caused the voles to overexpress V1aR, thereby increasing the density of vasopressin binding to the receptor. In addition to Dr. Young, the research group included Lauren J.
