Nature's weapon against nerve agents
An enzyme found naturally in the blood could help protect soldiers against the effects of the deadly nerve agent sarin.

Mouse genome will help identify causes of environmental disease
Research on the DNA of 15 mouse strains commonly used in biomedical studies is expected to help scientists determine the genes related to susceptibility to environmental disease.

Risk genes for multiple sclerosis uncovered
Using a whole-genome association scan, an international consortium of scientists has found genetic variations in multiple sclerosis patients, findings that suggest a possible link between MS and other autoimmune diseases.

Work-family stress studied among immigrant Latinos
A new study that examined the work-family experiences of recent Latino immigrants working in low-wage, nonprofessional jobs, found that they reported infrequent work-family conflict, according to lead author Joseph G.

Strains of laboratory mice more varied than previously thought
A collaborative study by scientists at the University of North Carolina at Chapel Hill and the Jackson Laboratory in Bar Harbor, Maine, has found that the genetic variation in the most widely used strains of laboratory mice is vastly greater than previously thought.

New technique to 'see' and protect transplants successful in diabetic animal model
Researchers at Johns Hopkins have found a way to overcome a major stumbling block to developing successful insulin-cell transplants for people with type I diabetes.

Using stem cells to help heart attack victims
New research at The University of Nottingham is paving the way for techniques that use stem cells to repair the damage caused by heart attacks.

First new multiple sclerosis gene found in 30 years
A newly identified gene may hold the promise of guiding future research into therapies for multiple sclerosis in what its discoverers say is the first major genetic advance in 30 years for understanding this nervous system disease.

Genetic finding sheds light on diseases causing blood vessel breakdown
Twenty-one years after they first described a fatal genetic disorder in Missouri and Arkansas families, scientists at Washington University School of Medicine in St.

Instant steam takes on MRSA
A method for making instant steam, without the need for electricity, promises to be useful for tackling antibiotic resistant

Study helps explain origins of cardiac fibrosis in patients with heart disease
A report led by researchers at Beth Israel Deaconess Medical Center (BIDMC) helps explain the origins of cardiac fibrosis, a stiffening of the heart muscle that leads to a variety of cardiac diseases, most notably heart failure.

Graphene sniffs out dangerous molecules
Researchers at the University of Manchester have used the world's thinnest material to create sensors that can detect just a single molecule of a toxic gas.

After a decades-long search, scientists identify new genetic risk factors for multiple sclerosis
A pair of large-scale genetic studies supported by the National Institutes of Health has revealed two genes that influence the risk of getting multiple sclerosis -- data sought since the discovery of the only other known MS susceptibility gene decades ago.

Research links genetic mutations to lupus
A gene discovered by scientists at Wake Forest University School of Medicine has been linked to lupus and related autoimmune diseases.

Frequency of Atlantic hurricanes doubled over last century, climate change suspected
About twice as many Atlantic hurricanes form each year on average than a century ago, according to a new statistical analysis.

¬°GI Caramba! Blue tortillas may help dieters and diabetics
A recent study suggests that blue corn tortillas are healthier than white, especially for diabetics and dieters.

System to analyze beating heart stem cells could lead to heart attack treatments
New research at the University of Nottingham, funded by the Biotechnology and Biological Sciences Research Council, is paving the way for techniques that use stem cells to repair the damage caused by heart attacks.
