The drug tadalafil, well-known by its brand name, Cialis, is normally taken for the bedroom, but in some circles it's catching on for a different purpose: longevity.
An experimental Alzheimer’s compound prevented damaging protein clumps from forming in the brains of mice, helping nerve cells survive longer and reducing amyloid buildup. The treatment also appeared
A centuries-old heart drug costing less than ten cents a day could help keep heart-failure patients out of the hospital. New research suggests low-dose digoxin can reduce heart-failure hospitalization
Exercise and healthy blood sugar levels in midlife may help slow cognitive decline decades later. Physical activity appeared especially beneficial for Mexican American adults, suggesting that some bra
A longtime Republican living in California says the Trump administration's continuing actions to target transgender youth take a personal toll.
Aging gradually wears down the cartilage and fluid that protect our joints, but avoiding movement may actually make matters worse. Exercise helps nourish cartilage, strengthens the muscles that protec

COVID-19 can reactivate dormant viruses hiding in the body, including Epstein-Barr, cytomegalovirus, and several herpes viruses. One poorly understood viral family was strongly associated with long CO
Rising carbon dioxide in the atmosphere may be leaving a measurable imprint inside the human body. Researchers analyzing more than two decades of U.S. health data found that blood bicarbonate levels h
Gut microbes need something to eat, and when fiber is limited, they may begin consuming proteins from the mucus lining that protects the gut. Researchers found that fiber can suppress this process, wh
A widely available food-preservation chemical is emerging as a disturbing factor in rising UK suicide deaths, particularly among younger people and men. Researchers say the scale may be underestimated
Scientists have uncovered why two seemingly opposite ways of targeting the same brain receptor can both promote weight loss. In mice, activating the GIP receptor in the brainstem reduced appetite, whi
Scientists have discovered that the aging human brain may be far less isolated from the rest of the body than once believed. Stanford researchers found that large numbers of immune cells from the bloo
Simply choosing the stairs could have surprisingly big benefits for your heart and longevity. A large analysis involving more than 480,000 people found that regular stair climbers were 39% less likely
A surprising stress-related signal may help the brain repair itself after injury. Researchers found that myelin-producing precursor cells rapidly release the stress hormone CRH near damaged brain tiss
Women who used estrogen-only hormone therapy later in life were less likely to develop dementia and showed fewer signs of Alzheimer’s disease in their brains, according to a large study of more than 2
