Researchers explore how certain molecular signaling pathways control aging across all species

Fruit flies are notoriously short-lived but scientists interested in the biology of aging in all animals have begun to understand why some fruit flies live longer than others. They have documented a direct association between insulin and life span, for example, and have observed a tradeoff between prolific reproduction and longevity. A new study, which may have broad implications across species, ties those findings more closely together by tracing an insulin signaling cascade through to protein quality control in muscle tissue and shortened life span.

New study looks at hormone/SNS relationship in women taking hormone contraceptives

After menopause, women's levels of estrogen and progesterone fall. Their formerly lower risk for heart disease equals, even surpasses, men's risk. One possible contributing explanation for the change in risk is that sex hormones affect the sympathetic nervous system, which controls constriction of blood vessels and participates in the fight or flight response.

New intravaginal ring delivers drug effectively, guards against HIV for 1 month

It's often said that the HIV/AIDS epidemic has a woman's face. The proportion of women infected with HIV has been on the rise for a decade; in sub-Saharan Africa, women constitute 60 percent of people living with disease. While preventative drugs exist, they have often proven ineffective, especially in light of financial and cultural barriers in developing nations.

New book on evolution and future of human reproduction

Human beings would probably be known as pilosals rather than mammals if Carl Linnaeus had not been a proponent of breast-feeding. For social and political reasons, the famed taxonomist labeled the class of animals to which humans belong with a reference to their practice of suckling their young rather than to their evolutionarily older characteristic of having hair.

Animal model of HIV sexual transmission

Infection by human immunodeficiency virus (HIV) causes acquired immunodeficiency syndrome (AIDS), a debilitating disorder in which progressive weakening of the immune system makes affected individuals more susceptible to potentially life-threatening infections and chronic diseases.
