Cystic fibrosis gene therapy trial results encouraging
Scientists and physicians in Cleveland have announced encouraging results from the first-of-its-kind gene therapy trial involving cystic fibrosis (CF) patients and a new compacted DNA technology.

Researchers find viral protein that mimics its way into cells
Researchers unraveling the biochemistry of a cancer-causing retrovirus have found a protein produced by the virus that has an uncanny resemblance to a key cell protein found in certain immune cells that helps control calcium signaling.

Brookhaven Lab scientists win 2003 Arthur J. Compton Award
Three scientists associated with the U.S. Department of Energy's (DOE) Brookhaven National Laboratory -- Martin Blume, Doon Gibbs, and Denis McWhan -- along with Kazumichi Namikawa of Gakugei University in Tokyo, Japan, have won the 2003 Advanced Photon Source Arthur H.

Researchers at Children's Hospital Boston report an important advance in tissue engineering of the penis, raising hopes that men with severe impotence - due to penile trauma, surgery, cancer, congenital malformations or other conditions - may someday be able to regain sexual function.

Destination Deadhorse...and beyond
In late March, the U.S. Navy established a camp on a severe and unforgivingly cold stretch of ice about 150 miles north of Deadhorse, Alaska.

Highway deaths highest for males - Male urban squirrels, that is
A year-long study on the Texas A&M University campus showed that males are more likely than females to die on the road, and scientists believe it's because the males dart about through the streets more.

Molecules trigger inflammation in Alzheimer disease
Neuroscientists report finding molecules playing a critical role in making the brain think it is under attack from Alzheimer disease plaques, triggering immune cells in the brain.

Study finds two-thirds of unplanned pregnancies in women using contraception
A survey on contraception by French researchers has found that a third of the pregnancies among women in their study were unplanned and that two-thirds of these pregnancies occurred in contraception users.
