Throw away your soap, detergent, and personal hygiene, the Japanese have invented odor-free underwear. Koichi Wakata, a Japanese astronaut living in the International Space Station, is testing the underwear created by textile experts at Japan Women's University in Tokyo. The shorts are designed to kill bacteria, absorb water, insulate the body and dry quickly. They also are flame-resistant, and anti-static. "The other astronauts become very sweaty, but he doesn't have any sweat. He didn't need to hang his clothes to dry. He can wear his trunks (underwear) more than a week," said Koji Yanagawa, an official with the Japanese Aerospace Exploration Agency.
