Green laser pointers can cause visible harm to the eye's retina

Mayo Clinic ophthalmologists have found commercially available Class 3A green laser pointers can cause visible harm to the eye's retina with exposures as short as 60 seconds. The findings will be published in the May issue of Archives of Ophthalmology.

Cocaine use increases the risk of coronary aneurysms

Researchers in Minnesota say that cocaine users may be putting themselves at risk of coronary aneurysms, a ballooning of the walls of coronary arteries, which is potentially fatal.

Many lives may be saved by new blood test for ovarian cancer

A new blood test which has the potential to save many lives has been developed to detect ovarian cancer, a disease known as the silent killer because it is so difficult to identify.

Gesturing while you talk linked to better speaking

Can't find the right word? You might want to start moving your hands. New research at the University of Alberta suggests that gesturing while you talk may improve your access to language.

New fat is needed to clear old fat from the system

Where fat comes from determines whether the body can metabolize it effectively. Researchers at Washington University School of Medicine in St. Louis have found that the "old" fat stored in the body's peripheral tissues -- that is, around the belly, thighs or bottom -- can't be burned efficiently unless "new" fat is eaten in the diet or made in the liver.

Metabolic syndrome costing four times that for all other patients

It is well known that hypertension, diabetes, and obesity are each taking a toll on Americans' health, but according to a new analysis, metabolic syndrome, a condition characterized by a combination of these and/or other risk factors, is fast becoming one of the nation's costliest health concerns.

"Anxiety Gene" linked to depression, makes the body out of tune

U.S. scientists in viewing the human body as a well-tuned orchestra, say that think they may have found a discordant note in the form of a gene which appears to increase the likelihood of some people developing anxiety and depression.

Persistent use of ecstasy leads to a loss of everyday memory

Persistent use of ecstasy leads to a loss of everyday memory, researchers from Northumbria University have discovered. For the study 23 regular users of ecstasy were compared to 30 people who had never used the drug.

Simple and efficient method for creation of novel protein functions in an existing protein scaffold

By designing a molecular bridge, scientists at the University of Illinois at Urbana-Champaign have forged a successful pathway through a complex ocean of barriers: They've changed the function of a protein using a co-evolution approach.

Researchers develop promising new gene network analysis method

Compared with a long-used linear model, a correlation-based statistical method is a more reliable way to map complex gene interactions and pinpoint genes that may be potential cancer treatment targets, according to new Brown University research.

Promising new molecular targets and treatment approaches for some of the most malignant brain tumors

The first study identified a protein that seems to control the malignant features of brain tumor cells, suggesting a new treatment target for anti-cancer drugs. Researchers found that a little-known protein called Fra-1 was effective in controlling vascular endothelial growth factor D, a factor that promotes the growth of new blood vessels in most malignant brain tumors.

Scientists take aim at virulent bacteria by decoding machinery of key control enzyme

By deciphering the ingenious mechanism used by a particular enzyme to modify bacterial chromosome chemistry, scientists have come a step closer to designing a new kind of drug that could stop virulent bacterial infections in their tracks. Their research will be published in the May 6 issue of the journal Cell.
