Genetically engineered cell becomes world's first living laser

It looks like we're one step closer to having laser vision (or at least, laser-based diagnostic and therapeutic techniques). Researchers at Harvard Medical School and Massachusetts General Hospital in Boston have genetically engineered the world's first "living laser." That's right - a living cell can shoot laser light. … » 6/13/11 1:22pm 6/13/11 1:22pm

Making nanomaterials just got a lot easier

Graphene is pretty cool stuff. It's the foundation of a lot of nanomaterials, and when it's only a single atom thick, it can stretch eternally in two dimensions. When it's more than one atom thick it behaves very differently, becoming graphite (which you often find in pencils). We already know a pretty easy way to get … » 3/04/11 8:30am 3/04/11 8:30am

X-Ray Hackers Show Tinest Crystalline Structure Ever Seen

What does this one-micron sized object look like to you? Despite what Freud would say, that boldly thrusting little guy is a microcrystal, once classified as a powder too tiny to be imaged using X-rays. But a bunch of European X-ray fiends have rigged up a special X-ray diffractor at the European Synchrotron Radiation… » 10/04/07 8:42am 10/04/07 8:42am
