Recent discoveries should aid research into cause of ALS

Two teams of researchers at Northwestern University have found a novel pathological hallmark of the neurodegenerative disease amyotrophic lateral sclerosis (ALS) at the molecular level. The neurologists and biochemists show how and why the mutated superoxide dismutase (SOD1) protein, which is associated with a familial form of ALS, becomes vulnerable and prone to aggregation and also provide evidence linking disease onset with the formation of intermolecular aggregates. more  

Brain study considers motor function, cognition with alcohol consumption

Dartmouth researchers are learning more about the effects of alcohol on the brain. They've discovered more about how the brain works to mask or suppress the impact that alcohol has on motor skills, like reaching for and manipulating objects. In other words, the researchers are learning how people process visual information in concert with motor performance while under the influence of alcohol. more

Girls have big advantage over boys on timed tests

New research attempting to shed light on the evergreen question--just how do male and female brains differ?--has found that timing is everything. more  

In utero exposure to urban air pollutants can increase risk

Prenatal exposure to air pollutants in New York City can adversely affect child development, according to the results of a study released today by the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University's Mailman School of Public Health. Previous studies have shown that the same air pollutants can reduce fetal growth (both weight and head circumference at birth), but this study, which examined a group of the same children at three years of age, is the first to reveal that those pollutants can also affect cognitive development during childhood. more

Study finds novel vaccine curbs brain tumor growth, increases survival 

A novel vaccine has significantly increased life expectancy in patients with glioblastoma multiforme (GBM), the most dangerous type of brain tumor, a researcher from The University of Texas M. D. Anderson Cancer Center is reporting at the annual meeting of the American Association of Neurological Surgeons (AANS). more

Heart attack patients do better at hospitals following guidelines  

In findings that researchers say should help hospitals improve care for their heart patients, Duke University Medical Center cardiologists have demonstrated that hospital adherence to national guidelines for treating patients with potential heart attacks saves lives. more

Implantable cardioverter-defibrillators have higher malfunction rate than pacemakers

Although pacemakers and implantable cardioverter-defibrillators (ICDs) sustain and save many lives and have a low malfunction rate, their performance should be monitored, especially ICDs, which have a significantly higher malfunction rate than pacemakers, according to two studies in the April 26 issue of JAMA. more

 

Females have a significant advantage over males on timed tests and tasks. Reearchers found the differences were particularly significant among pre-teens and teens.
