Vampire Clothing

Yarn that feeds on blood. That's certainly something the world needs more of. Luckily, the University of Michigan has invented bloody yarn that conducts electricity.

It's supposed to be exciting because it's (partly) an advance in nanotechnology. The yarn is coated in carbon nanotubes by soaking it in a special solution, and the nanotubes conduct electricity. By adding anti-albumin to the solution, the yarn conducts even more electricity when it comes into contact with blood.

Personally, I think this sounds about as useful as that clothing that changes color when your body temperature changes. The researchers have high hopes, though. They think that the clothes can be tied into a device like a cellphone or PDA so that when people start bleeding, the device calls for help (electronically, by calling an emergency service, not, like, by screaming loudly). We'll just have to wait and see how they do with that.
