The Six Billion Dollar Man is getting a little bit closer, not just to movie theaters, but in real life. 

A new development toward a prosthetic retina could help counter conditions that result from retinal degeneration, a life-altering health issue for many people, especially as they age.

Trans fats are bad, they damage metabolic health in kids, according to experts and policy makers. So they were banned. Happy Meals too. And drinks with sugar.

It's fashionable in nutritional circles to demonize sodas but they also embrace a lot of unsubstantiated food fads. How much real prospective fact-finding has gone into their beliefs?

FK506 binding protein 51 (FKBP51) is an Hsp90 co-chaperone and regulator of the glucocorticoid receptor, and consequently of stress physiology. It regulates acute and chronic effects of treatment with antidepressants via autophagic pathways (processes by which cells break down and recycle their components) in mice and is linked to the clinical response to antidepressants in humans, according to a new paper. 

Did you spend those pre-school years telling your child how smart and wonderful they are? School is going to be an unwelcome dose of reality.
