BHI expresses concern over use of long-range acoustic devices

In preparation for the thousands of anti-war activists expected to protest outside the NATO summit in Chicago this week, the city has reportedly ordered $1 million worth of riot-control equipment including a 'sound cannon' that can be used to emit pain-inducing sound waves of up to 150 decibels.

New method can detect and monitor pH changes in living brains

University of Iowa neuroscientist John Wemmie, M.D., Ph.D., is interested in the effect of acid in the brain. His studies suggest that increased acidity or low pH, in the brain is linked to panic disorders, anxiety, and depression. But his work also suggests that changes in acidity are important for normal brain activity too.

Scientists map how XIAP protein activates vital component of immune defence system

Defects in the gene that encodes the XIAP protein result in a serious immune malfunction. Scientists used biochemical analyses to map the protein's ability to activate vital components of the immune system. Their results have recently been published in Molecular Cell, a journal of international scientific repute.

Breast cancer vaccine that elicits powerful immune response also improves recurrence rates

A breast cancer vaccine already shown to elicit a powerful immune response in women with varying levels of HER2 expression has the ability to improve recurrence rates and is well tolerated in an adjuvant setting, according to new research from a clinical trial led by researchers at The University of Texas MD Anderson Cancer Center.

The truth about chocolate: does it really contain flavonoids?

There have been many news stories over the years about chocolate and whether it is good or bad for you. The stories often comment on a chemical constituent of chocolate: flavonoids. But what are flavonoids? Does chocolate even contain them? And why should we care if it does?

Study demonstrates impact of epilepsy on child and parent sleep patterns

Researchers from Massachusetts General Hospital for Children in Boston have determined that pediatric epilepsy significantly impacts sleep patterns for the child and parents. According to the study available in Epilepsia, a journal published by Wiley-Blackwell on behalf of the International League Against Epilepsy (ILAE), sharing a room or co-sleeping with their child with epilepsy decreases the sleep quality and prevents restful sleep for parents.

Simple pull-to-sit task could predict risk of ASD in infants

A new prospective study of six-month-old infants at high genetic risk for autism identified weak head and neck control as a red flag for autism spectrum disorder (ASD) and language and/or social developmental delays.

Researchers identify novel base modification in RNA

Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics that DNA consists of only four bases.

RAL proteins linked with aggressive cancer characteristics in human tumors

We have known for years that when the proteins RalA and RalB are present, cells in dishes copy toward aggressive forms of cancer. However, until this week, no study had explored the effects of RAL proteins in human cancers - an essential step on the path to developing drugs to target these proteins.

Study identifies age and marital status as factors in parental happiness

New research by psychologists at three North American universities, including the University of British Columbia, finds that parents experience greater levels of happiness and meaning from life than non-parents.

Researchers sequence genomes of 21 breast cancers

In two back-to-back reports published online on 17 May in Cell, researchers have sequenced the genomes of 21 breast cancers and analysed the mutations that emerged during the tumours' development. The individual results are described below.

Damage to brain white matter connections may be the cause of Phineas Gage's behavioral changes

Poor Phineas Gage. In 1848, the supervisor for the Rutland and Burlington Railroad in Vermont was using a 13-pound, 3-foot-7-inch rod to pack blasting powder into a rock when he triggered an explosion that drove the rod through his left cheek and out of the top of his head. As reported at the time, the rod was later found, "smeared with blood and brains."

Fitness fanatic dad becomes research pioneer after kidney disease diagnosis

A super-fit father who rowed the distance from the Equator to the North Pole on a rowing machine has told of how his experience of kidney disease led to him becoming the first patient to take part in a groundbreaking research study run in Sheffield and Leeds.

Marathon runners less likely to die during or soon after the race

Even though hundreds of thousands more people finished grueling 26.2 mile marathons in the United States in 2009 compared to a decade earlier, a runner's risk of dying during or soon after the race has remained very low — about .75 per 100,000, new Johns Hopkins research suggests. Men, however, were twice as likely to die as women.

Dangerous, complex migraines linked to high risk for stroke

Nicole Soriano had headaches before but nothing like the one that struck in the middle of one summer night. A coincidence led nine days later to Cedars-Sinai Medical Center, where a rare type of migraine was diagnosed and treated - but any moment during that time could have been disastrous.

Delayed loss of nerve cells in the brain linked to symptoms of depression following stroke

Several weeks after mild brain ischemia, mice display a depressive-like syndrome characterized by increased anxiety, inactivity and "cheerlessness". These symptoms of depression following a stroke are associated with the delayed loss of nerve cells in the brain's reward regions. This is the major finding of a study published in the current issue of Biological Psychiatry.
