Japanese astronauts are testing out some water-absorbent, anti-bacterial, and supposedly odour-resistant underwear (among other clothing) which can be worn for a month straight. I'll be thankful that I'm not in the Gizmodo offices when the guys decide to try these.
When he returns to earth, astronaut Koichi Wakata is handing his underwear (boxers or briefs, I wonder) over to scientists to study how well everything held up after being worn for a month straight.
The supposed reason behind this test is to make astronauts' lives easier since there isn't a way to wash clothing in space, but I have the distinct feeling that the technology will be abused in horrible, horrible ways.
