Powerful genetic studies reveal secrets of adult and childhood inflammatory bowel disease
Two of the largest ever studies of the genetics of inflammatory bowel disease -- one looking at ulcerative colitis, the other at childhood-onset inflammatory bowel disease -- have identified key genetic regions which increase susceptibility to these conditions.

Protein changes in heart strengthen link between Alzheimer's disease and chronic heart failure
A team of US, Canadian and Italian scientists led by researchers at Johns Hopkins report evidence from studies in animals and humans supporting a link between Alzheimer's disease and chronic heart failure, two of the 10 leading causes of death in the United States.

Postmortem genetic tests after sudden death may provide less expensive way to identify risk
Postmortem testing to identify mutations associated with sudden cardiac death is less expensive than comprehensive cardiac tests for surviving relatives.

Researchers find potential treatment for Huntington's disease
Investigators at Burnham Institute for Medical Research, UBC and UCSD have found that normal synaptic activity in nerve cells protects the brain from the misfolded proteins associated with Huntington's disease.

NIST demonstrates 'universal' programmable quantum processor
Physicists at the National Institute of Standards and Technology have demonstrated the first

MIT scientists pinpoint origin of dissolved arsenic in Bangladesh drinking water
Researchers in MIT's department of civil and environmental engineering believe they have pinpointed a pathway by which arsenic may be contaminating the drinking water in Bangladesh, a phenomenon that has puzzled scientists, world health agencies and the Bangladeshi government for nearly 30 years.

Elevated biomarkers lead to diminished quality of life in heart attack patients post-discharge
Many heart attack patients have high levels of cardiac biomarkers in the blood for several months after leaving the hospital, with more shortness of breath and chest pain, according to a Henry Ford Hospital study.

Study finds mixed results comparing 2 surgical strategies for infant heart defect
Researchers found mixed results in the first head-to-head comparison of two surgeries for infants born with severely underdeveloped hearts -- the most common severe heart birth defect.

Heart and bone damage from low vitamin D tied to declines in sex hormones
Researchers at Johns Hopkins are reporting what is believed to be the first conclusive evidence in men that the long-term ill effects of vitamin D deficiency are amplified by lower levels of the key sex hormone estrogen, but not testosterone.

Tiny bubbles clean oil from water
Small amounts of oil leave a fluorescent sheen on polluted water.

American College of Medical Informatics inducts new Fellows
Following their recent election, 11 new Fellows were inducted into the American College of Medical Informatics this evening at ceremonies that raise the curtain on the opening of the Biomedical and Health Informatics Symposium tomorrow at the Hilton San Francisco.

Largest gene study of childhood IBD identifies 5 new genes
In the largest, most comprehensive genetic analysis of childhood-onset inflammatory bowel disease, an international research team has identified five new gene regions, including one involved in a biological pathway that helps drive the painful inflammation of the digestive tract that characterizes the disease.

Climate variability and dengue incidence
Research published this week in PLoS Medicine demonstrates associations between local rainfall and temperature and cases of dengue fever.

Warmer means windier on world's biggest lake
Rising water temperatures are kicking up more powerful winds on Lake Superior, with consequences for currents, biological cycles, pollution and more on the world's largest lake and its smaller brethren.

Tiny particles can deliver antioxidant enzyme to injured heart cells
Researchers have developed microscopic polymer beads that can deliver an antioxidant enzyme made naturally by the body into the heart.

The GFC is bad for more than just your pocket
One in four Australian adults has taken an action that puts their health at risk as a result of the global financial crisis (GFC), according to a new MBF Healthwatch poll.

Continuous chest compression-CPR improved cardiac arrest survival in Arizona
The chance of surviving a cardiac arrest outside a hospital was found to be twice as high when bystanders performed continuous chest compressions without mouth-to-mouth breathing than when bystanders performed standard CPR.

Early cooling in cardiac arrest may improve survival
In a European study, patients were more likely to survive without brain damage after a cardiac arrest if emergency medical technicians lowered their body temperature early during resuscitation.

Today's children decide their school and career path early
Children as young as 12 have a strong sense of their personal futures and can reflect thoughtfully on what life might hold for them, according to new research funded by the Economic and Social Research Council and led by Professor Paul Croll of Reading University and Professor Gaynor Attwood of the University of the West of England.

Young athletes need dual screening tests for heart defects, study suggests
To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
