nanotechnology stories

The science of holography has taken a big leap forward thanks to tiny carbon nanotubes. Scientists at Cambridge University have used carbon nanotubes to generate the smallest hologram pixels ever created. The small size is key, because the smaller the pixel, the higher the resolution of the hologram and the wider the field of view.
Until now, stitches and surgical sutures have acted matter-of-factly as medical tools — they close your wound until the incision or cut heals. Now, there's a new kind of suture on the horizon, one that comes fitted with micro-thin sensors to monitor the health of the wound, as well as deliver healing heat to the site on the fly.
Piezoelectric generators take motion and turn it into electricity. They've been used to convert muscle movement into energy to run medical implants, but it's been hard to get them to scale up enough to power stuff that's bigger and more fun. Researchers at Georgia Tech have been able to create a tiny piezoelectric nanogenerator that's capable of powering an LED and a liquid crystal display, and your iPod is going to be next.
