Newman was able to do away with most of that dead weight, thanks to her studies of how people move in outer space. Among other things, she's studied ways to modify beds and treadmills in space, so astronauts don't lose so much muscle mass and bone density. So the revolutionary BioSuit uses mechanical counterpressure (from tight inner layers) instead of gas to keep the suit pressurized. That way, the next generation of space explorers will look slinky and move easy. Image courtesy of MIT.
