First discovery announced of a planet orbiting giant star
A team of astronomers from the University of California, San Diego and two other institutions has made the first discovery of a planet orbiting a giant star, a find of special interest to astronomers because it provides insight into the fate of planets during the late life cycles of stars.

New treatment extends life for patients with small-cell lung cancer
A new treatment for a fatal form of lung cancer holds the promise of dramatic improvement in survival for many patients, says a Vanderbilt-Ingram Cancer Center physician.

Researchers say new star structures found in the Milky Way alter galactic model
Heidi Jo Newberg, associate professor of physics at Rensselaer Polytechnic Institute, and Brian Yanny, an astrophysicist at Fermi National Accelerator Laboratory, who are leading a team of researchers with the Sloan Digital Sky Survey (SDSS), announced today they have identified new star structures in the halo of the Milky Way that could alter the standard model of the galaxy.

Novel simulations of turbulent reacting flows provide insight into physics of internal combustion
Using a computational method called direct numerical simulation, researchers at the University at Buffalo have performed simulations of turbulent reacting flows that are the closest to date to a true model of the physics of chemically reacting turbulent flows.

Basis of rare genetic illness leads to better understanding of bone formation, Hopkins researchers find
Scientists at Johns Hopkins and three other centers have found that defects in GNAS1, a hormone sensitivity gene, are responsible for progressive osseus heteroplasia (POH), a disease that causes rice-size bone fragments to spontaneously form under the skin and inside internal organs.

BSE in sheep: First estimates of human death toll
The first attempt to estimate the human health risk from possible BSE infection of the British sheep flock is published today by researchers from Imperial College, London.

Thrill rides may be mysterious cause of neurological symptoms
With the advent of amusement park rides reaching G-forces that exceed those experienced by astronauts on the space shuttle, emergency physicians may be seeing a significant increase in head, neck and back trauma, warned an article in the January 2002 Annals of Emergency Medicine.

Vasectomies without surgery
Scalpel-free vasectomies might encourage more squeamish men to be sterilised.

The strong magnetic fields produced by some electric appliances and vehicles increase the risk of miscarriage, claim researchers in California.

Turbulence and thick gas are clues to galactic evolution
In a huge river of primordial hydrogen flowing from the neighboring Magellanic Clouds into our Milky Way galaxy, astronomers at the Arecibo observatory have found the first evidence of turbulence and concluded that the invisible, hot mass of gas surrounding our galaxy is much thicker than physicists previously thought.
