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

In search of cosmic mayhem

A physicist at Washington University in St. Louis working with scientists at the Smithsonian Institution is unveiling the dark, violent side of the universe.

Studying the highest energy photons known to science, Washington University Associate Professor of Physics James H. Buckley, Ph.D., and his colleagues are analyzing bursts of gamma rays released from massive black holes at the center of so-called active galaxies.

Two of the three largest impact craters on Earth have nearly the same size and structure, researchers say, but one was caused by a comet while the other was caused by an asteroid. These surprising results could have implications for where scientists might look for evidence of primitive life on Mars.

Susan Kieffer of the University of Illinois at Urbana-Champaign, Kevin Pope of Geo Eco Arc Research and Doreen Ames of Natural Resources Canada analyzed the structure and stratigraphy of the 65 m
