Good side to cholesterol in controlling cell signals

Cholesterol, often stigmatized for its role in heart disease, has long been known to be essential for the health of the fat-laden membranes that surround individual cells.

First genetic marker to help identify ruptured brain aneurysm

Mayo Clinic researchers have discovered a genetic marker that may pave the way for a fast, inexpensive blood test to predict one type of deadly stroke that strikes 30,000 people in the United States annually.

Autistic children shy from eye contact because they perceive even the most familiar face as an uncomfortable threat

The work deepens understanding of an autistic brain's function and may one day inform new treatment approaches and augment how teachers interact with their autistic students.

Definitive evidence that TRPV3 is a temperature sensor

The human brain is like a general in a bunker. Floating in its bubble of cerebrospinal fluid, it has no direct window to the outside world, so the only way for the brain to observe, comprehend, and order the body into action is to rely on information it receives.

New method of organising care for adults in the UK who suffer from clinical depression

Researchers at the University of York are investigating a new method of organising care for some of the three million adults in the UK who suffer from clinical depression.

Findings might advance search for new therapies for injured nerve fibers

Long distance messengers star in many heroic tales, perhaps the most famous being the one about the runner who carried the news about the victory of the Greeks over the Persians in the fateful battle of Marathon.

Clearance of beta amyloid accumulation within neurons stops memory decline

Researchers at UC Irvine have identified a trigger at the molecular level that marks the onset of memory decline in mice genetically engineered to develop brain lesions – in the form of plaques and tangles – associated with Alzheimer's disease.

Proteins link cellular aging and response to calorie restriction

In the March 3 issue of Nature, Johns Hopkins researchers report that two proteins best known for very different activities actually come together to turn the liver into a sugar-producing factory when food is scarce.

A man's index finger length relative to ring finger length can predict how physically aggressive that man might be

Dr. Peter Hurd a psychologist at the University of Alberta, and his graduate student Allison Bailey, have found that a man's index finger length relative to ring finger length can predict how physically aggressive that man might be.

Deep brain stimulation alleviates severe depression

Canadian researchers have found that severe depression, which is often unresponsive to standard treatments, may be alleviated with an experimental treatment called deep brain stimulation.

Radiologists can estimate the risk of death to a SARS patient by using chest radiographs

Radiologists can estimate the risk of death to a SARS patient by the seventh day from the onset of symptoms by using chest radiographs, according to a new study by researchers in Hong Kong. This early determination can allow a physician to better tailor treatment for the SARS patient.

Psychologist examines the narcissistic personality in terms of its ability to forgive

When harsh words or actions tear a relationship apart, forgiveness can sometimes mend it. Because forgiveness implies letting go of justified feelings of resentment, it can be costly in terms of pride. Certain types of people--those with a high sense of narcissistic entitlement--may be especially reluctant to face the costs of forgiving others, according to Case Western Reserve University psychologist Julie Exline.

Dopamine sheds new light on drug addiction

A paper published in the current issue of Science has challenged beliefs about the role of dopamine in the brain, which could lead to new treatments for Parkinson’s disease, schizophrenia and drug addiction. The research suggests that dopamine has a far wider, less specialised role than previously hypothesised.

Meditation may reduce heart disease risk

Black adolescents with high normal blood pressure who practice transcendental meditation improve the ability of their blood vessels to relax and may reduce their risk of becoming adults with cardiovascular disease, researchers say.

Visual cortex contains neurons that are sensitive to viewing angle

Mistakes made by human subjects in identifying the facing direction of faces, cars or meaningless objects have yielded evidence that the brain contains nerve cells, or neurons, whose job is to encode the viewing angle of objects. It is well known that certain neurons respond to color, motion, edges and other aspects of our environment.

Discovery gives clinicians new targets for making existing therapies more effective and developing drugs to inhibit the growth of cancers

A team of researchers at the University of Alberta in Edmonton and the Samuel Lunenfeld Research Institute in Toronto have discovered how a key enzyme involved in repairing DNA is put together and how it works--a development that opens up new therapies for making cancer cells more vulnerable to attack.

Important advance in our understanding of colorectal cancer

An international team of medical scientists has made an important advance in our understanding of the second most fatal form of cancer in the industrialized world. Professor Jeremy R. Jass, who holds a Canada Research Chair in Gastrointestinal Pathology at McGill University in Montreal

Abnormal brain structure tied to spatial, numerical thinking problems when children lack part of chromosome

Certain genetic diseases affect children's educational abilities in a distinctive pattern: impairing their numerical abilities more than their verbal skills. New research sheds light on this split in abilities by investigating how differences in brain structures may influence how the mind works.

Genetic cause of dyslexia

A gene which is likely to be one of the causes of dyslexia in children has been discovered by researchers at Cardiff University.

Inflammation is a strong risk factor for cardiovascular disease among rheumatoid arthritis patients

Mayo Clinic epidemiologists have found that the systemic inflammation characterizing rheumatoid arthritis may be to blame for the increased risk of cardiovascular death in patients with the disease.
