International research group led by UMass scientist sequences genome of ubiquitous microbe
... cells regulate genes. We have not observed such a sophisticated regulatory network in such a primitive organism before." DasSarma says that a handful of organisms in the archaea have been sequenced before, but this is the first halophile, or salt-loving organism. Because they can live under extreme conditio...Californian wins neuroscience prize endowed by UNC scientist

Remarkably, it then turned out that the receptor also mediates responses to noxious heat." Moreover, the only neurons in the entire nervous system that express the receptor VR1......,000 to 1,000,000 genetic figures, requires highly sophisticated data processing tools. Addressing this and similar challenges may soon be easier thanks to Prof. Eytan Domany of the Weizmann Institute's Physics of Complex Systems Department and doctoral students Gad Getz and Erel Levine. The team has designed ...Sensor uses DNA to detect presence of lead, a dangerous contaminant

Now, researchers at the University of Illinois have developed a simple and inexpensive method that permits real-time, on-site detection of lead ions. A unique feature of our lead sensors is that they consis...Female birds choose best singers to have smarter offspring

PHILADELPHIA - The body's immune system has sophisticated safeguards in place to prevent it from turning its destructive power against the body's own cells. Immune cells with the capability of attacking the self are readily identified in healthy individuals, and these cells are typically purged from the sys...New study reveals a major cause of global warming - ordinary soot
