EAST LANSING, Mich. — Each year, an estimated four million Americans experience adverse reactions to prescription medications. Many of these reactions, ranging from mild rashes and drowsiness to hospitalization and death, could be avoided if warning labels were more effective, according to a Michigan State University study.

Researchers from the Peninsula College of Medicine and Dentistry, University of Exeter, in collaboration with colleagues from Rutgers University, Newark and University College London, have furthered understanding of the mechanism by which the cells that insulate the nerve cells in the peripheral nervous system, Schwann cells, protect and repair damage caused by trauma and disease.

Scientists have managed to switch on and off the magnetism of a new material using quantum mechanics, making the material a test bed for future quantum devices.

The research led by Newcastle University's Dr Mark Cunningham and Professor Miles Whittington and supported by the Dr Hadwen Trust for Humane Research, indicates a novel electrical bio-marker in humans.

The brain produces electrical rhythms and using EEG - electrodes on the scalp - researchers were able to monitor the brain patterns in patients with epilepsy. Both in patients and in brain tissue samples the team were able to witness an abnormal brain wave noticeable due to its rapidly increasing frequency over time.

Recent work in mice suggested that the immune system is involved in removing beta-amyloid, the main Alzheimer's-causing substance in the brain. Researchers have now shown for the first time that this may apply in humans.

The first large non-commercial study to investigate whether the main active constituent of cannabis (tetrahydrocannabinol or THC) is effective in slowing the course of progressive multiple sclerosis (MS) shows that there is no evidence to suggest this; although benefits were noted for those at the lower end of the disability scale.

People make complex judgements about a person from looking at their face that are based on a range of factors beyond simply their race and gender, according to findings of new research funded by the Economic and Social Research Council (ESRC).

The findings question a long-held belief that people immediately put a person they meet into a limited number of social categories such as: female or male; Asian, Black, Latino or White; and young or old.

A study recently published in the Endocrine Society's Journal of Clinical Endocrinology and Metabolism (JCEM) suggests that vitamin D—when taken with calcium—can reduce the rate of mortality in seniors, therefore providing a possible means of increasing life expectancy.

When the going gets tough, the tough ought to thank their fathers.

New research from Brigham Young University shows that dads are in a unique position to help their adolescent children develop persistence.

BYU professors Laura Padilla-Walker and Randal Day arrived at these findings after following 325 families over several years. And over time, the persistence gained through fathers lead to higher engagement in school and lower rates of delinquency.

Chevy Chase, MD—Exposure to low doses of Bisphenol A (BPA) during gestation had immediate and long-lasting, trans-generational effects on the brain and social behaviors in mice, according to a recent study accepted for publication in the journal Endocrinology, a publication of The Endocrine Society.

WASHINGTON – Cyclists in Washington, D.C. who use Capital Bikeshare for their daily commutes are much less likely to wear helmets than commuters on their own bikes. That is the finding from an observational study conducted by Georgetown University School of Nursing & Health Studies (NHS) researchers that compares the rate of helmet use of casual and commuting Bikeshare riders with private cyclists. The research was published today in the American Journal of Public Health.

Visual and auditory stimuli that elicit high levels of engagement and emotional response can be linked to reliable patterns of brain activity, a team of researchers from The City College of New York and Columbia University reports. Their findings could lead to new ways for producers of films, television programs and commercials to predict what kinds of scenes their audiences will respond to.

Amsterdam, NL, June 14, 2012 – No effective treatments are currently available for the prevention or cure of Alzheimer's disease (AD), the most frequent form of dementia in the elderly. The most recognized risk factors, advancing age and having the apolipoprotein E Ɛ4 gene, cannot be modified or treated. Increasingly, scientists are looking toward other risk factors to identify preventive and therapeutic strategies.

People who were sexually unfaithful without their partner's knowledge were less likely to practice safe sex than those who had other sexual relationships with their partner's consent. They were also more likely to be under the influence of drugs and alcohol at the time of the encounter.

In a study published in The Journal of Sexual Medicine, researchers from the University of Michigan, USA, found that condom use for vaginal and anal sex was 27% and 35% lower in sexually unfaithful relationships and drug and alcohol use was 64% higher.

INDIANAPOLIS -- A new study shows that a practical clinical tool developed by researchers from the Regenstrief Institute and the Indiana University School of Medicine to measure severity of dementia symptoms is reliable and valid. The Healthy Aging Brain Care Monitor is simple, user-friendly and sensitive to change in symptoms.
