Water Temperatures, Pollution Have Oysters In Hot WaterOysters exposed to high water temperatures and a common heavy metal are unable to obtain sufficient oxygen and convert it to cellular energy, as per a new study presented at The American Physiological Society conference, Comparative Physiology 2006.
The study showed how cadmium, a heavy metal, reduces the oyster's tolerance of warmer water temperatures and makes it more vulnerable during the summer when water temperatures rise. Half of the........Go to the My-media-blog (Added on 10/11/2006 5:03:01 AM)
Giant Insects Might ReignThe delicate lady bug in your garden could be frighteningly large if only there was a greater concentration of oxygen in the air, a new study concludes. The study adds support to the theory that some insects were much larger during the late Paleozoic period because they had a much richer oxygen supply, said the study's lead author Alexander Kaiser.

Decaffeinated coffee is not caffeine-freeCoffee addicts who switch to decaf for health reasons may not be as free from caffeine's clutches as they think. A new study by University of Florida scientists documents that almost all decaffeinated coffee contains some measure of caffeine.

Why Unexpected Dennis Surge Occurred?When Hurricane Dennis passed North Florida on July 10, 2005, it caused a 10-foot storm surge in some areas along Apalachee Bay -- about 3 to 4 feet more than forecasted-- that couldn't be explained only by the local winds that conventionally drive storm surge.
