Boys outnumber girls at extremely high levels of math ability and scientific reasoning: Study

A study that examined 30 years of standardized test data from the very highest-scoring seventh graders has found that performance differences between boys and girls have narrowed considerably, but boys still outnumber girls by more than about 3-to-1 at extremely high levels of math ability and scientific reasoning.

Study finds link between early nutrition and arthritis in people and moose

It's seen as a sign of getting old, but scientists have discovered that arthritis is not just a human problem as a study lasting 50 years reveals how moose suffer from an identical form of the condition. The research, published in Ecology Letters, also casts new light on how malnutrition early in life can lead to the disorder in both moose and humans.

Social, psychological factors rather than biological changes influence women's sexual behaviour during menopause

New research from the University of Sheffield has found that social and psychological factors have the biggest influence upon women's sexual behaviour during the menopause, rather than biological changes such as declining hormone levels.

Map of herpes virus "cell-entry machinery" provides new target for antiviral drugs

The mechanism by which a herpes virus invades cells has remained a mystery to scientists seeking to thwart this family of viruses. New research funded by the National Institutes of Health and published online in advance of print in Nature Structural & Molecular Biology reveals the unusual structure of the protein complex that allows a herpes virus to invade cells. This detailed map of a key piece of the herpes virus "cell-entry machinery" gives scientists a new target for antiviral drugs.

MJFF announces $1.1M for projects to develop biomarker candidates for PD

The Michael J. Fox Foundation for Parkinson's Research today announced nearly $1.1 million for projects aimed at advancing the development of leading biomarker candidates for Parkinson's disease. The discovery and validation of biomarkers is of critical importance to increasing the speed and efficiency of PD therapeutic development, allowing scientists and clinicians to more accurately identify appropriate subjects for clinical studies, measure disease progression and monitor treatment effects in clinical trials.

If you witness rudeness you are more likely to make mistakes, says Professor of Applied Psychology

If someone is rude to you at work or if you witness rudeness you are more likely to make mistakes, says Rhona Flin, Professor of Applied Psychology at the University of Aberdeen, in an editorial published in this week's BMJ.

Drug use debilitates sexual response: Study

Sharing a bottle of red wine may seem like the best recipe for a romantic interlude. However, the evening may not turn out as planned according to a Concordia University study, which evaluated the effect of a wide range of drugs, including alcohol, on sexual behaviour. The findings, published in the journal Hormones and Behavior, definitively show that despite our preconceived notions, use of many recreational drugs can cause a loss in that lovin' feeling.

Trigger that induces B cells to produce early, effective antibody response discovered

Researchers at National Jewish Health have discovered a trigger that induces B cells to produce effective and long-lived antibodies early in the immune response. They found that a molecule that binds toll-like receptors doubles the early antibody response to an antigen, and shifts it to a more effective, IgG form.

Researchers identify key players in biochemical pathway that regulates blood pressure

Researchers at the University of Pittsburgh School of Medicine have identified key players in a little-known biochemical pathway that appears to regulate blood pressure. The findings, reported in the early online version of Cardiovascular Research, have evolved from studies conducted by Jeffrey S. Isenberg, M.D., Eileen M. Bauer, Ph.D., and their colleagues at Pitt's Vascular Medicine Institute.

Study shows gene-environment interaction in congenital heart disease

A pregnant mother's diet may be able to interact with the genes her unborn child inherits and influence the type or severity of birth defect according to research funded by the Wellcome Trust and the British Heart Foundation. The study, published in the journal Human Molecular Genetics, suggests that mothers who eat a high fat diet before and through pregnancy could be inadvertently putting the health of their offspring at risk.

New insights into dendritic spine deficits in schizophrenia

Dendritic spines act as hubs for communication between nerve cells. Reductions in spines may contribute to a lack of coordination in activity between brain regions. This structural abnormality is particularly relevant in schizophrenia, where pyramidal neurons located in layer 3, the principal cell type receiving communication from other brain regions, have fewer dendritic spines.

Rejection by romantic partner associated with brain's motivation, reward and addiction craving centers

Researchers have linked rejection by a romantic partner to brain activity associated with motivation, reward and addiction cravings, according to a study published in the July issue of the Journal of Neurophysiology. Lucy Brown, Ph.D., clinical professor in the Saul R. Korey Department of Neurology and of neuroscience at Albert Einstein College of Medicine of Yeshiva University, is the corresponding author of the study.

Research could lead to remote stimulation of cells to treat cancer or diabetes

Clusters of heated, magnetic nanoparticles targeted to cell membranes can remotely control ion channels, neurons and even animal behavior, according to a paper published by University at Buffalo physicists in Nature Nanotechnology.

Study finds decline in homicide, suicide rates among mentally ill people

People with mental health problems are committing fewer homicides while the number of suicides by mental health patients has also fallen, latest figures reveal; a previous rise in homicides by mentally ill people may have been the result of drug misuse, says the report.

Study identifies factors that control production of HSCs

A team of researchers from the Institute for Research in Immunology and Cancer of the University of Montreal have made significant progress in the understanding of blood-producing (hematopoietic) stem cells. The study led by IRIC Chief Executive Officer and Scientific Director, Dr. Guy Sauvageau, identifies factors that control the production of hematopoietic stem cells.

TGen develops G-SQZ technique for genomic data processing

A new computer data compression technique called Genomic SQueeZ, developed by the Translational Genomics Research Institute, will allow genetic researchers and others to store, analyze and share massive volumes of data in less space and at lower cost.

Biotage launches AFFINILUTE Molecularly Imprinted Polymer columns for analytical sample preparation

Biotage, a leading supplier of tools and technology for analytical and medicinal chemistry, announced the introduction of high-performance, AFFINILUTE MIP (Molecularly Imprinted Polymers) columns for analytical sample preparation. Highly selective extractions with AFFINILUTE MIPs are considerably simplified resulting in faster, more robust and ultimately lower cost sample preparation.

TWINCORE researchers develop new model approaches for HCV research

The hepatitis C virus is highly specialised. We humans are its natural hosts. The only other living organisms that could be infected with the hepatitis C virus in the lab are chimpanzees. Nevertheless it is - from the viewpoint of the virus - highly successful: around 170 million people are chronically infected with the virus. And with the chronic infection the risk of developing liver cancer also increases.

Slow rate of living and reduced energy metabolism is sufficient to increase longevity: Study

Don't put down the red wine and vitamins just yet, but if you're taking antioxidants because you hope to live longer, consider this: a new study published in the June 2010 issue of the journal GENETICS casts doubt on the theory that oxidative stress to our tissues shortens lifespan. That's because researchers from McGill University in Canada have identified mutations in 10 different genes of worms (genes believed to have counterparts in humans) that extend their lifespan without reducing the level of oxidative stress the worms suffer.

New research shows cellular changes in fat tissue lead to type 2 diabetes

Cellular changes in fat tissue-not the immune system-lead to the "hyperinflammation" characteristic of obesity-related glucose intolerance and type 2 diabetes, according to new research from the University of Cincinnati.
