Tropical forests -- Earth's air conditioner

...ests in colder, sub-polar latitudes evaporate less water and are less effective at producing clouds. As a result, the main climate effect of these forests is to increase the absorption of sunlight, which can overwhelm the cooling effect of carbon storage. However, Caldeira believes it would be counterpr...

... squid may be going down there at night is because water near the surface is really warm—up to 82 F—and they may be getting stressed," Gilly explained. "The squid is using energy all of the time, because it has to swim to breathe. So when it gets into really warm water, I think it gets out pretty quickly. ...

...ions, there are a limited number of surfers in the water during each heat and the skill level is very high. On the other hand, recreational surfers are often trying to catch waves in a dense crowd of surfers of varying abilities," says Nathanson. The authors note that although age and gender had no bea...

A new study of living cells could revolutionize the way we test drugs

... how to improve the sensitivity of the detector in water and next time we will also use a more active micro-organism such as an amoeba. Yeast is a subdued organism and doesn’t generate much activity," says Professor Geim. "Probably, the most important outcome is that we defined an important goal. Cellular ...

Despite these significant differences in fishing "effort" and cost, Maine has only about 30% higher catches than the Canadian Fishing Area. Accordingly, the researchers estimate that the number of traps used in Maine is 13 times gr...

However, this destroys the natural folding structure of the protein membranes, which is precisely what makes t...
