Spray-on skin is helping child burns victims cope with the trauma of scarring, according to a study by University of Queensland researchers at the Royal Children's Hospital in Brisbane.

Through studying pigeons with genetic heart disease, researchers at Wake Forest University School of Medicine have discovered a clue about why some patients' heart vessels are prone to close back up after angioplasty.

A family of proteins that serve as the body's first line of defense against bacterial infections may provide a lifeline for individuals with compromised immune systems, according to researchers at the Indiana University School of Medicine – Northwest.

A new way of delivering corrective genes with a single injection into a vein holds promise for long-lasting treatments of hereditary diseases of the heart, University of Florida researchers report.

Scientists have long known that epidemics of dengue fever wax and wane over a period of several years, but they've never been quite sure why. With the incidence and range of the potentially deadly mosquito-borne illness increasing, understanding the factors that influence these epidemics has never been more important.

A relatively benign compound contained in a widely used group of insecticides can mix with and increase the toxicity of existing pesticides in the environment, according to a new study led by biologists at the University of California, Berkeley.

A drug made to enhance memory appears to trigger a natural mechanism in the brain that fully reverses age-related memory loss, even after the drug itself has left the body, according to researchers at UC Irvine.

A household remedy millennia old is being reinstated: honey helps the treatment of some wounds better than the most modern antibiotics. For several years now medical experts from the University of Bonn have been clocking up largely positive experience with what is known as medihoney. Even chronic wounds infected with multi-resistant bacteria often healed within a few weeks. In conjunction with colleagues from Düsseldorf, Homburg and Berlin they now want to test the experience gained in a large-scale study, as objective data on the curative properties of honey are thin on the ground.

New research shows that a chemical compound found in many air fresheners, toilet bowl cleaners, mothballs and other deodorizing products, may be harmful to the lungs. Human population studies at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health, found that exposure to a volatile organic compound (VOC), called 1,4 dichlorobenzene (1,4 DCB) may cause modest reductions in lung function.
