An analysis of yearly vehicle deaths compared to gas prices found death rates drop significantly as people slow down and drive less. If gas remains at $4 a gallon or higher for a year or more, traffic fatalities could drop by more than 1,000 per month nationwide, according new findings.

A new study -- done on a scale an order of magnitude greater than anything previously attempted in the field of malaria -- has uncovered an arsenal of proteins produced by the malaria parasite that allows it to hijack and remodel human red blood cells, leaving the oxygen-carrying cells stiff and sticky.

Diabetes in men has a direct effect on fertility, a scientist told the 24th annual conference of the European Society of Human Reproduction and Embryology. Despite the prevailing view that it had little effect on male reproductive function, researchers have now shown that diabetes caused DNA damage in sperm.

Researchers have created a list of prescription drugs that increase the risk of falling for patients aged 65 and older who take four or more medications on a regular basis.

Farm-raised tilapia, one of the most highly consumed fish in America, has very low levels of beneficial omega-3 fatty acids and, perhaps worse, very high levels of omega-6 fatty acids, according to new research. The researchers say the combination could be a potentially dangerous food source for some patients with heart disease, arthritis, asthma and other allergic and auto-immune diseases that are particularly vulnerable to an "exaggerated inflammatory response."

Scientists report a remarkable improvement in Alzheimer's transgenic mice following treatment with a new drug. The study provides the first demonstration that an ionophore, a compound that transports metal ions across cell membranes, can elicit rapid and pronounced improvement in neuropathology and cognitive function in mouse models of Alzheimer's Disease.

Using ultrasound to measure the height of a woman's uterus is a good way to predict whether or not she is at risk of having babies born prematurely if she becomes pregnant with twins after IVF, according to new research presented at the 24th annual meeting of the European Society of Human Reproduction and Embryology in Barcelona.

While Maria Lyzen was being treated for breast cancer, she found she couldn't concentrate or decipher information, and just functioning day-to-day at home was difficult. "I didn't know if it was a reaction to the trauma of being told that I had breast cancer. I was in my late 50's -- was it the beginning of an aging symptom? Or was it the drugs that I was getting in terms of my chemotherapy? My doctor ordered a brain scan, and there was nothing unusual there, and I said, 'But there is something wrong with me,'" Lyzen says.

A group of aging experts report that the best strategy for preventing and fighting a multitude of diseases is to focus on slowing the biological processes of aging.

Nearly one-third of women reported pronounced asymmetry between their breasts after breast cancer surgery, and that perceived disfigurement greatly affects a woman's quality of life after treatment, according to a new study by researchers. A poor aesthetic outcome after lumpectomy is linked to depression and fear.
