UCSF researchers move in on role of brain's naturally occurring marijuana
Previously, researchers determined that the brain contains a molecule that mimics the active ingredient in marijuana, but its location and role were unclear.

Study identifies culprits in food allergy inflammation
A new study has definitively linked a type of food allergy whose occurrences have risen dramatically in recent years to eosinophils, a type of cell usually found in the blood.

How fat kills heart cells
Droplets of stored lipids accumulate in the cytoplasm of cardiac myocytes in a variety of cardiomyopathies, ranging from such chronic conditions as diabetes and obesity to the pathology that leads to sudden death in otherwise healthy young people.

Dual-purpose clothing for SEALS
What every SEAL needs is a dual-purpose suit to wear comfortably in and out of the water.

Spiders eyes for Mars robots
Planetary robots will be able to see better using a trick borrowed from jumping spiders.

Massive infant stars rock their cradle
Extremely intense radiation from newly born, ultra-bright stars has blown a glowing spherical bubble in the nebula N83B, also known as NGC 1748.

$7.5 million grant aims to close cancer gap between blacks, whites
The National Cancer Institute has awarded $7.5 million to support expansion of an innovative partnership between Meharry Medical College and the Vanderbilt-Ingram Cancer Center.

Using the Internet responsibly for market research
Consumers can look forward to kinder, gentler market survey techniques -- and fewer of those annoying phone calls during dinner -- if market researchers take heed to a Penn State researcher's recent findings about ways to use the Internet.

Spinal cord stimulation vs. reoperation: Rush-Presbyterian-St. Luke's Medical Center
Orthopedic surgeons at Rush-Presbyterian-St. Luke's Medical Center in Chicago are conducting a clinical study to determine which treatment -- a second surgery or a spinal cord stimulator -- is most effective at helping relieve pain after low back surgery

Fogarty International Center establishes Sheldon M. Wolff, MD Fellowship On International Health
The new Sheldon M. Wolff, M.D. Fellowship on International Health provides opportunities for American Association for the Advancement of Science Fellows in the Science, Engineering, and Diplomacy Program to work at the Fogarty International Center on program, policy, and planning initiatives.

University of Florida researchers identify a protein that may induce drug resistance in lung cancer cells
Florida researchers have identified a protein that appears to play a key role in fortifying lung cancer cells against the powerful chemotherapy drugs designed to kill them.

From quarks to quasars: major spring physics meeting
The theme for the American Physical Society (APS) Spring Meeting is

Decorin as a conduit for Lyme disease bacteria
As Lyme disease progresses past the early stage of a rash in the region of the initial infection, spirochetes circulate throughout the body and infect various organs.

New technique overturns assumption on light-generated nitric oxide molecules
A new technique developed by University at Buffalo chemists that combines X-ray diffraction with laser excitation has fundamentally altered a widely held assumption dating back 25 years about what happens to certain types of molecules that play a basic role in body chemistry when they are pumped with laser light.

Most people with allergy-like symptoms don't have allergies, study says
In a recent study of 246 patients, researchers found that nearly two out of three patients treated for allergies were not allergic.

Penn researchers explain the mechanics behind the delayed effects of brain trauma; findings may chart paths to therapeutic relief
Researchers at the University of Pennsylvania Medical Center have determined how calcium ions fill neurons following head trauma, causing long-term memory dysfunction.

NMR researcher Alexander Pines wins Carnegie Mellon Dickson Prize in Science
On April 12, Carnegie Mellon University will award its $50,000 Dickson Prize in Science to Alexander Pines, a professor of chemistry at the University of California at Berkeley, for his contributions to the field of nuclear magnetic resonance (NMR).

Radioactive tumbleweeds
Beware tumbleweeds or migrating ducks - they may have been contaminated with radiation.

Mouse model of food allergies reveals cause of inflammation
In a study that might one day lead to new treatments for some food allergies and related diseases, a team of researchers has shown how certain immune cells attack the digestive tract of mice fed specially treated food.

Sequencing the human genome: unraveling the mysteries of health and disease
AAAS is presenting a series of breakfast seminars on concerns related to genetic discrimination for Members of Congress, their staffs, and the interested public.

Eye strips images of all but bare essentials before sending visual information to brain, UC Berkeley research shows
Recent studies at UC Berkeley show that the metaphor of the eye as a camera is more poetic than real.

Radiation 'hazards' found at U.S. Capitol, Library of Congress buildings
Radiation levels up to 65 times higher than U.S. Environmental Protection Agency safety standards were measured at the U.S.

Mechanism for generating autoimmunity-suppressing cells identified
Scientists at The Wistar Institute have identified the immune system's mechanism for generating regulatory T cells, critical in preventing autoimmunity.

Collagen and osteoporosis
Common conditions such as osteoporosis often show clear evidence for a genetic component, but pinning the risk of disease on a specific genetic polymorphism is notoriously tricky in these cases. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
