"Today, surgeons are able to harvest and reimplant as few as two hairs at a time, making the transplants look more natural. Still, the supply-and-demand problem remains. In the early 1990s, Colin Jahoda, a researcher at the University of Durham in England, took a step toward solving it. He stripped a few cells off the root of a mouse's whisker follicle and implanted them into its ear. Out grew a whisker. Next he took a section of follicle cells from his own head and implanted it between the fine, pale hair on his wife's arm. A thick, dark hair emerged, complete with male DNA. This demonstrated that the cells at the base of a follicle can and do regenerate into self-contained, preprogrammed hair factories."Saturday, January 19, 2008

Johnny Lee, Will You Marry Me?
Joli and I just bought a Wii, and we have been playing the games nearly every night, marveling at the function of the machine. In tennis, if you tilt your wrist inward on a return shot, you hit cross-court, something that has recently amazed me in its accuracy. (Sadly, I am unable to do such things in real life.) Yet I haven't spent much time wondering what's inside the thing. To me, it has just been a magical white box that allows me and Joli to go bowling in our living room.But Johnny Chung Lee, a PhD-seeking graduate student at Carnegie Mellon University has already hacked the device to use in other applications, such as an interactive white board and a head-tracking display device, which makes a 3D display possible (videos of both projects are posted below).
It's guys like this who make computer science seem like punk rock.
