Surprise discovery helps tackle rabies

In an unexpected discovery, scientists at Jefferson Medical College have found that a tiny change in a rabies virus protein can turn a "safe" virus extremely deadly. The finding has enabled the researchers to refine a vaccine they previously created against rabies in wildlife, making it safer and more effective.

Genetic risk factors for depression greater in women

Virginia Commonwealth University researchers have found that genes contribute more strongly to the risk of depression in women than in men, and that there may be some genetic factors that are operating uniquely in one sex and not in the other.

Elevated homocysteine levels may be a biomarker for increased risk of AMD

People who have elevated homocysteine in their blood, an amino acid that is a known biomarker for cardiovascular disease, may also be at an increased risk of developing age-related macular degeneration (AMD), according to a study in the January issue of the American Journal of Ophthalmology.
