Weight control protein may yield antiobesity drugs

...ui said. Moreover, the animals developed severely elevated blood sugar, insulin, and leptin concentrations. Elevated leptin levels are a hallmark of leptin resistance, a primary risk factor for obesity, he added. Further examination found that the animals lacking SH2-B ate nearly twice as much as normal. Su...

...ations were conducted at only a few locations, the elevated carbon-14 levels in the atmosphere rapidly equalized around the globe," he said. Since atmospheric testing was banned in 1963, the levels have dropped substantially as the carbon-14 reacted with oxygen to form carbon dioxide, which was taken up by pl...

Anthrax stops body from fighting back, study shows

...he 2001 anthrax attacks. The victims did not have elevated white blood cell counts, typical for most infections, and a large number of the inhaled anthrax bacteria had spread from the lungs into the bloodstream, which is unusual, Southwick said. This led researchers to believe anthrax may be impairing the c...

Agricultural workers at increased risk for infection with animal flu viruses

CO2 sensing proves critical for fungal pathogens to adapt to life in air and human hosts

...cans and C. neoformans are exposed to dramatically elevated CO2 concentrations when causing systemic disease. In their research, the authors identify CO2 as a physiological signal that induces the pathogenic filamentous transition in C. albicans; they also demonstrate that an ancient group of enzymes called a...

Breath of the dragon: ERS-2 and Envisat reveal impact of economic growth on China's air quality
