Women's cognitive decline associated with interrupted or fitful sleep

Women who experienced cognitive decline over a 13 to 15 year period after age 65 were more likely to sleep poorly than women whose cognition did not decline, according to a study led by researchers at the San Francisco VA Medical Center (SFVAMC).

Myeloid-derived suppressor cells suppress anti-tumor response to cancer

Scientists at Johns Hopkins and elsewhere say they have mapped out an escape route that cancers use to evade the body's immune system, allowing the disease to spread unchecked.
