If you've seen the 1989 film "Back to the Future Part II," you've at least considered how awesome hover-boarding would be, if not full-on fantasized about cruising around every day on a flying skateboard. Well if a new Y...

The specific proportions of immune cells in a blood sample form a profile that can indicate disease or exposure to a toxicant. A new epigenetic technique provides a reliable way to detect such profiles, even in archived ...

It may seem normal: As we age, we misplace car keys, or can't remember a name we just learned or a meal we just ordered. But researchers say memory trouble doesn't have to be inevitable, and they've found a drug therapy ...

Women with distal radius (wrist) fractures had decreased strength compared to similar patients without fractures, a new study shows. This could explain why these women were more likely to fall and might sustain future fr...

Three promising biomarkers being studied to detect Alzheimer's disease in its early stages appear to undergo a surprising shift as patients develop symptoms of dementia, researchers report. Scientists found in a recent s...
