Researchers at Johns Hopkins Children's Center report that adults born with ambiguous genitalia - or malformations that make it difficult to determine sex of rearing - were generally content with the gender assigned to them at birth by their parents and doctors.

Laboratory study explains clinical promise of anti-angiogenesis cancer drug
New laboratory research results are telling cancer researchers exactly how an experimental copper-lowering drug works against cancer, by blocking the molecular signals that tumors need to send in order to grow blood vessels that can feed their growth.

Artificial liver trials show progress, as transplant candidates wait
Four years after the first American clinical trial of an experimental artificial liver system began at the University of Michigan, its leader says he is encouraged by the results thus far.

From parasitism to mutualism
In the September issue of Ecology Letters, Johnstone and Bshary demonstrate that when coral reef fish approach a 'cleaner' wrasse to have their parasites removed, the cleaner can take advantage of the client by biting living tissue as well.

Early mental health intervention reduces mass violence trauma
Early psychological intervention guided by qualified mental health caregivers can reduce the harmful psychological and emotional effects of exposure to mass violence in survivors, according to a national conference report released today.

Satellites to profile weather, improve forecasts through GPS
A revolutionary globe-spanning satellite network will furnish round-the-clock weather data, and monitor climate change by intercepting signals from the Global Positioning System (GPS).

NASA scientists determined to unearth origin of the Iturralde Crater
NASA scientists will venture into an isolated part of the Bolivian Amazon to try and uncover the origin of a 5 mile (8 kilometer) diameter crater there known as the Iturralde Crater.

The CEBAF Large Acceptance Spectrometer (CLAS) delves into secrets of particle's structure
JLab researchers utilized CLAS and CEBAF's 5.7 GeV continuous beam to gather new insights on several fundamental questions about the neutron.

New procedure kills liver tumors without surgery
The week after Carlton Harris underwent a novel therapy at the Duke Comprehensive Cancer Center to destroy three cancerous liver tumors, he was back at the gym huffing, puffing, lifting and sweating.

Proposed remedy for forest fires puts economic interests first
President Bush's current call for reducing the restrictions on logging in national forests counters nearly 30 years worth of federal policy, according to an Ohio State University researcher who wrote a new book on government forest issues.

In a paper soon to appear in Ecology Letters, Tebbich and colleagues present the first study on the ecological relevance of tool-use by a bird species.

Jefferson Lab's Hall C first to measure neutron's electric charge density distribution
Physicists have long known that neutrons are slightly positive at the core and slightly negative at the surface but overall are electrically neutral.
