Stanford cooling tool may improve performance of athletes, soldiers

...system on which the palm of the hand rests], which cools the blood in the hand's vascular heat-exchange structures. Arteries deliver blood directly from the heart to these vascular structures, and veins then carry the blood from these structures back to the heart." Grahn and Heller, animal physiologis...

Genetically endowed worm may substitute for rodents in some toxicology testing

...ial colonies the worms use as food. After the agar cools and solidifies in the sunken wells where the animals will live, machines add drops of bacteria. Robots also measure out chemicals at various levels of dilution and place those in the wells. Meanwhile, another machine, called a "biosorte...

Story tips from the Department of Energy's Oak Ridge National Laboratory

...y by "waste" heat. This "fuel free" chilled water cools one-million-square-feet of building space at a mixed use site. The cooling, heating and power system is expected to operate at 70 to 80 percent efficiency, compared with 55 percent efficiency in the best central power plants. The system will be monit...

How running made us human

...from the scalp, forehead and face, the evaporation cools blood draining from the head. Veins carrying that cooled blood pass near the carotid arteries, thus helping cool blood flowing through the carotids to the brain. A more balanced head with a flatter face, smaller teeth and short snout, compared w...

Fatter pigs due to cooling

...arly spraying water from a sprinkling installation cools down the overheated pigs. As a result of this their feed intake and therefore their growth rate increases. Pigs are highly sensitive to the ambient temperature. They cannot actively sweat and the evaporation of water from the lungs is also limited. ...

Satellite technology allows scientists to track warm sharks in cold polar seas

...heart, which is constantly flooded with blood that cools to ambient water temperatures as it passes through...r warm, active bodies with blood even as the heart cools to 35 F. "This is clearly a unique shark species--the warmest of all gill-breathers in the ocean," B...

North Sea efficient sink for carbon dioxide

...e winter, the surface water in the cold polar seas cools down and becomes slightly heavier. As a result of this it sinks under its own weight into the deep sea. The second way is by algae fixing carbon dioxide under the influence of sunlight (photosynthesis). This mechanism is important in the North Sea. ...

Deep-rooted plants have much greater impact on climate than experts thought

...the tap roots," said Dawson. "Just as perspiration cools us off, increased transpiration by trees in June and July explains the drop in temperature in the Amazon." This effect changes the way the atmosphere heats and cools, and will change the way rain is distributed, he noted. Depending on the extent to w...

Genes offer researchers a 'crystal ball' to help them prevent, diagnose and treat cancer

...to a commercially available handheld device, which cools the air, forming a condensed vapor, to which the methylation assay is applied. Investigators found it could detect the presence of the methylated form in all six tumor suppressor genes. For RASSF1A, the test was negative in non-smokers, and positive...

Aerosol pollution slows down winds and reduces rainfall

...n, and prevent it from getting to the ground. This cools the Earth's surface and reduces daytime vertical convection that mixes the slower winds found near the ground with the faster winds at higher altitudes. The overall effect is a reduction in the speed of near-surface winds, which Jacobson has calculat...

AGU Journal highlights -- February 23, 2007

...eats up more rapidly than water during the day and cools off more rapidly at might. The cycling of cold and warm air creates rotating pockets of high and low pressures, forming a circulation cell that propagates both onshore and offshore. Hunter et al. studied SLB circulation using data collected from Febr...

Volcanic plumbing dictates development of deep-sea hydrothermal vents

...between the mantle and crust is not aligned, magma cools and volatiles are lost as the magma moves laterally, he said. Most of the magma then remains under the sea floor. For years, geologic theory has predicted that magma production alone is vital to fuel hydrothermal vents, or the hot smokers where mi...

Taking Greater Manchester as their model, the team used Geographic Information System (GIS) mapping to build up a picture of the conurbatio...
