Excess brain activity in aMCI patients contributes to brain dysfunction underlying memory loss

An existing anti-seizure drug improves memory and brain function in adults with a form of cognitive impairment that often leads to full-blown Alzheimer's disease, a Johns Hopkins University study has found.

Key finding sheds new light on common bleeding disorders

A simple cut to the skin unleashes a complex cascade of chemistry to stem the flow of blood. Now, scientists at Washington University School of Medicine in St. Louis have used evolutionary clues to reveal how a key clotting protein assembles. The finding sheds new light on common bleeding disorders.

Genetically engineered excitable cells made to generate and pass electrical current

By altering the genetic makeup of normally "unexcitable" cells, Duke University bioengineers have turned them into cells capable of generating and passing electrical current.

Localized one-time gene therapy might effectively protect against atherosclerosis

A one-dose method for delivering gene therapy into an arterial wall effectively protects the artery from developing atherosclerosis despite ongoing high blood cholesterol.

Receptor GPR56 could have a critical role in cancer progression

Melanoma is devastating on many fronts: rates are rising dramatically among young people, it is deadly if not caught early, and from a biological standpoint, the disease tends to adapt to even the most modern therapies, known as VEGF inhibitors.

Caffeine reduces women's chances of becoming pregnant

Caffeine reduces muscle activity in the Fallopian tubes that carry eggs from a woman's ovaries to her womb. "Our experiments were conducted in mice, but this finding goes a long way towards explaining why drinking caffeinated drinks can reduce a woman's chance of becoming pregnant," says Sean Ward, professor of physiology and cell biology, at the University of Nevada School of Medicine, who conducted the study.

New rapid test accurately distinguishes bacterial and viral infections

Researchers at Ben-Gurion University of the Negev (BGU) have developed a new test that quickly and accurately distinguishes between bacterial and viral infections in as little as five hours.

Loss of critical male development gene causes male cells to become female

University of Minnesota Medical School and College of Biological Sciences researchers have made a key discovery showing that male sex must be maintained throughout life.

Inherited forms of Alzheimer's could be detected long before memory problems develop

Inherited forms of Alzheimer's disease may be detectable as many as 20 years before problems with memory and thinking develop, scientists will report July 20, 2011, at the Alzheimer's Association International Conference on Alzheimer's Disease in Paris.

Computer modeling to predict how peripheral nerve axon responds to electrical stimuli

Researchers at Case Western Reserve University have developed a computer modeling method to accurately predict how a peripheral nerve axon responds to electrical stimuli, slashing the complex work from an inhibitory weeks-long process to just a few seconds.

Researchers influence activity of nerve cells with laser light

Unlike conventional methods, with the so-called optogenetics, the researchers are able to target one cell type. "We are now going to use this method to find out exactly what goes wrong in the nerve cells in movement disorders such as ataxias", said Prof. Dr. Stefan Herlitze.

Researchers identify IDOL protein as potential new target for lowering LDL cholesterol

High levels of 'bad' cholesterol (LDL cholesterol) are a risk factor for developing atherosclerotic cardiovascular disease (ASCVD) - a disease of the major arterial blood vessels that is one of the major causes of heart attack and stroke.

Intense visual stimulation renders nerve cells more receptive to subsequent learning

Dr. Ed Ruthazer is a mapmaker but, his landscape is the developing brain - specifically the neuronal circuitry, which is the network of connections between nerve cells. His research at The Montreal Neurological Institute and Hospital - The Neuro at McGill University, reveals the brain as a dynamic landscape where connections between nerves are plastic, changing and adapting to the demands of the environment.

Maltodextrin-based imaging probes could improve diagnosis and treatment of bacterial infections

A new family of contrast agents that sneak into bacteria disguised as glucose food can detect bacterial infections in animals with high sensitivity and specificity. These agents -- called maltodextrin-based imaging probes -- can also distinguish a bacterial infection from other inflammatory conditions.

Humans and zebrafish share mechanisms that regulate the circadian system

Circadian rhythms - the natural cycle that dictates our biological processes over a 24-hour day - does more than tell us when to sleep or wake. Disruptions in the cycle are also associated with depression, problems with weight control, jet lag and more. Now Prof. Yoav Gothilf of Tel Aviv University's Department of Neurobiology at the George S. Wise Faculty of Life Sciences is looking to the common zebrafish to learn more about how the human circadian system functions.
