Inner-ear membrane uses tiny pores to mechanically separate sounds

Even in a crowded room full of background noise, the human ear is remarkably adept at tuning in to a single voice - a feat that has proved remarkably difficult for computers to match.

Non-academic contemporaries take brain stimulants more often than students

Three per cent of young men in Switzerland take cognitive enhancement drugs at least once each year. Students hope this consumption will improve their exam performance, while their non-academic contemporaries seek primarily to remain awake for longer.

Restless legs syndrome alters expression of critical gene during fetal development of brain

In a study published online in Genome Research, researchers of the Helmholtz Zentrum München und the Technische Universität München have demonstrated that a common genetic variant associated with Restless Legs Syndrome (RLS) alters the expression of a critical gene during fetal development of the brain.

New improved mass spectrometry for analysis of chemical and biological materials

When it comes to analyzing cell components or body fluids or developing new medications, there is no way around mass spectrometry. Mass spectrometry is a highly sensitive method of measurement that has been used for many years for the analysis of chemical and biological materials.

Neurexin proteins play key role in formation of synaptic connections

Neuroscientists and bioengineers at Stanford are working together to solve a mystery: how does nature construct the different types of synapses that connect neurons -- the brain cells that monitor nerve impulses, control muscles and form thoughts.

CLL patients more prone to infections due to reduced number of antibodies

People with chronic lymphocytic leukaemia (CLL) are essentially more prone to infections such as varicella, influenza or pneumococci due to the reduction in the number of antibodies that their condition causes.

Sea lions exposed to toxin in algae develop form of epilepsy that is similar to humans

California sea lions exposed to a toxin in algae develop a form of epilepsy that is similar to one in humans, according to a new study led by Stanford University School of Medicine researchers.

Biologists discover WBC moves to inflamed sites by walking in a stepwise manner

A team of biologists and engineers at the University of California, San Diego has discovered that white blood cells, which repair damaged tissue as part of the body's immune response, move to inflamed sites by walking in a stepwise manner.

Quail and chickens are likely sources of infection of H7N9 influenza virus to humans

Among the copious species of poultry in China, quail and chickens are the likely sources of infection of H7N9 influenza virus to humans, according to a paper published ahead of print in the Journal of Virology.

Higher genetic risk of obesity may amplify effects of fried food consumption on body weight

People with a genetic predisposition to obesity are at a higher risk of obesity and related chronic diseases from eating fried foods than those with a lower genetic risk, according to a new study from researchers from Harvard School of Public Health, Brigham and Women's Hospital, and Harvard Medical School.

Findings support development of cysteine protease inhibitors as new drug target for AD

A team of scientists from the University of California, San Diego School of Medicine, the Medical University of South Carolina and San Diego-based American Life Science Pharmaceuticals, Inc., report that cathepsin B gene knockout or its reduction by an enzyme inhibitor blocks creation of key neurotoxic pGlu-Aβ peptides linked to Alzheimer's disease (AD). Moreover, the candidate inhibitor drug has been shown to be safe in humans.

Compound from "third-hand smoke" damages DNA and potentially cause cancer

Leftover cigarette smoke that clings to walls and furniture is a smelly nuisance, but now research suggests that it could pose a far more serious threat, especially to young children who put toys and other smoke-affected items into their mouths.
