High doses of the hormone progesterone can kill neuroblastoma cells while leaving healthy cells unscathed, scientists at Emory University School of Medicine have found...

While depression and anxiety have long been recognised as risk factors for heart disease, there is less certainty over the beneficial effects of a 'positive' psychological state, Now, following a study of almost 8000 British civil servants, researchers say that a satisfying life is indeed good for the heart.

Doctors have known for a long time that prostate cancer "runs in the family." Men with relatives who have been diagnosed with prostate cancer have an elevated risk of also developing this type of cancer.

New research reports a high prevalence of vitamin D insufficiency and deficiency among patients with psoriatic arthritis. Seasonal variation in vitamin D levels was not observed in patients in southern or northern locations.

A link between chemicals called phthalates and thyroid hormone levels was confirmed by the University of Michigan in the first large-scale and nationally representative study of phthalates and BPA in relation to thyroid function in humans.
