Novel silicon-based gas sensors offer potential for low-cost arrays integrated with electronics
A new type of sensor based on porous silicon and a unique metallization process could offer enhanced sensitivity, reduced power demands and lower cost compared to existing technologies for detecting gaseous compounds important in environmental, food and biomedical applications.

Baldness induced by dopamine treatments may be reversible
Two women with Parkinson's disease who developed alopecia (baldness) while being treated with the dopamine agonists pramipexole or ropinirole found that the hair loss stopped after the drugs were discontinued and replaced with a new treatment.

Three-month antibiotic treatment reduces risk of future heart attack
An antibiotic prolonged life and reduced risk of future heart attacks in people hospitalized for heart attack or unstable angina, according to a report in today's rapid access issue of Circulation: Journal of the American Heart Association.

Adaptable nanotubes make way for custom-built structures, wires
Tiny self-assembled tubes, about 1/1,000th the width of a grain of sand, may now be used as a scaffold to custom-build molecular wires and other components for use in nanometer-sized electronic devices, including some that could be inserted into the body.

Treating eye pain may remove other migraine symptoms
Eye pain is an oft-accompanied symptom of migraine sufferers. Researchers have found that treating inflammation in the eye's trochlea tendon can relieve the headache pain associated with migraines, or prevent the triggering of full-blown migraine attacks.

Scientists seek women who suffer from PMS
University of North Carolina at Chapel Hill researchers are looking for women who experience an especially debilitating form of premenstrual syndrome -- a medical condition called premenstrual dysphoric disorder -- to participate in a new study of the illness.

Yale-designed protocol addresses problems that are often overlooked in the elderly
Yale researchers have designed a geriatric assessment protocol to identify problems that often go undetected in elderly patients, such as depression, incontinence, vision and hearing loss and driving safety issues.

Air pollution causes healthy blood vessels to constrict
For the first time researchers have shown that air pollution negatively affects the blood vessels of healthy humans, according to a study in today's rapid access issue of Circulation: Journal of the American Heart Association.

UVES investigates the environment of a very remote galaxy
Observations with ESO's Very Large Telescope (VLT) have enabled an international group of astronomers to study in unprecedented detail the surroundings of a very remote galaxy, almost 12 billion light-years distant.

Lethal heart condition traced to cocaine use
Cocaine can cause a lethal tearing in the heart's main artery, a condition that should be suspected in people treated for chest pain at urban hospitals, say researchers in today's rapid access issue of Circulation: Journal of the American Heart Association.

'Star Wars' like technology closer than galaxies far away
High-intensity focused ultrasound (HIFU) devices target ultrasound in precise locations for non-invasive surgical treatments.

$6 million grant to expand search for autism genes
NIMH today awarded to researchers at UCLA the first installment of an expected $6 million grant over 5 years to add 300 more families to the Autism Genetic Resource Exchange (AGRE) gene bank.

Cocaine use associated with often fatal heart condition
Cocaine use can be associated with a potentially fatal condition called aortic dissection, according to UCSF researchers.

NSF invites media to report on arctic research cruise to study early indicators of climate change
The National Science Foundation (NSF), through its Office of Polar Programs, is accepting written requests from professional journalists to join a research cruise in Alaskan waters as part of the Western Arctic Shelf-Basin Interactions project (SBI), which looks at possible indicators of climate change in the Chukchi and Beaufort Seas.

In heart failure, beta-blockers boost survival advantage for women
Beta-blockers benefit women as much as men, according to one of the largest studies to examine gender differences in treating heart failure, researchers report in today's rapid access issue of Circulation: Journal of the American Heart Association.
