Rebecca Onie asks audacious questions: What if waiting rooms were a place to improve daily health care? What if doctors could prescribe food, housing and heat in the winter?

Every cell in the human body has a sex, which means that men and women are different right down to the cellular level. Yet too often, research and medicine ignore this insight -- and the often startlingly different ways in which the two sexes respond to disease or treatment. As pioneering doctor Paula Johnson describes in this thought-provoking ...

Call it "geo-medicine."

At TEDMED, Eric Dishman makes a bold argument: The US health care system is like computing circa 1959, tethered to big, unwieldy central systems: hospitals, doctors, nursing homes. As our aging population booms, it's imperative, he says, to create personal, networked, home-based health care for all.
