In the race to cure cancer, researchers look for roadblocks that could stop cancer in its tracks, preventing it from spreading to other parts of the body. Scientists from the University of Wisconsin-Madison may have found that blockade – an enzyme critical to the ability of cells to metastasize, a biological phenomenon by which cells migrate. The findings are published in the Nov. 7 issue of the journal Nature.

“The real, life-threatening problem with most cancers is that they migrate away

JASON II reaches most of the world ocean floor and sends data ashore via the Internet

A new generation of remotely operated vehicle (ROV) capable of routine operation to depths of 6,500 meters (21,320 feet) and communicating its data back to shore via the Internet has been developed by the Woods Hole Oceanographic Institution (WHOI). The vehicle, JASON II, recently completed its first science cruise off the coast of Washington and Oregon and is currently at sea in the Pacific wo

Mechanical engineers at Purdue University have discovered a simple and speedy method for pinpointing and fixing design flaws in new cars.

Douglas E. Adams, an assistant professor of mechanical engineering at Purdue, said he stumbled across a mathematical solution to a design bottleneck in automotive engineering. Engineers now have to rely on complex, time-consuming mathematical models to solve design problems in new cars that are soon to begin rolling off the assembly line.

University of North Carolina at Chapel Hill researchers report a 50 percent reduction in the number of deaths among kidney hemodialysis patients who are given a new drug that helps prevent excess phosphorus from accumulating in the bloodstream. “The drug, lanthanum carbonate, is effective. It’s well-tolerated, and patients find it reasonably easy to take,” said Dr. William Finn, nephrologist and professor of medicine at UNC.

Study findings will be presented Saturday (Nov. 2) at the Amer

VLT UVES Observes Most Metal-Deficient Star Known [1]
A faint star in the southern Milky Way, designated HE 0107-5240, has been found to consist virtually only of hydrogen and helium. It has the lowest abundance of heavier elements ever observed, only 1/200,000 of that of the Sun – 20 times less than the previous record-holding star.

This is the result of a major ongoing research project by an international team of astronomers [2] . It is based on a decade-lon

Researchers from the University of Pittsburgh Medical Center have made significant progress in identifying the first susceptibility gene for clinical depression, the second leading cause of disability worldwide, possibly providing an important step toward changing the way doctors diagnose and treat major depression that affects nearly 10 percent of the population.

Research results, which were accepted for rapid publication and published today in the American Journal of Medical Genetics, sho
