NASA's Human Research Program is all about risk reduction, finding ways to counter fatigue and mitigate radiation damage, among other potential issues in space travel. But what if a different kind of program had evolved?

Tibetans handle high altitudes much better than most people. New research pinpoints the genes that allow them to breathe easily on mountain peaks, and avoid deadly side-effects.

A one-time intelligence analyst with the Pentagon, Aimee Mullins is an athlete, model, and activist. And she does it all using a collection of experimental prosthetic legs. She says her special "cheetah" legs give her superpowers.
