Scientists at UCLA have constructed the world's smallest light bulb. When it's turned off, the tiny filament is invisible to the naked eye. Flip the switch, however, and it becomes a tiny pin-prick of light. The minuscule bulb was created using carbon nanotube technology, a much touted scientific breakthrough that has, until now, been used to do little else other than create portraits of our ...

Scientists are hard at work developing the next generation of tiny batteries, and, instead of using dangerous chemicals and heavy metals, they're using viruses -- real, bacteria-eating viruses. For the first time, researchers at MIT recently used these little guys to build the world's first virus-built, Lithium-ion battery. Turns out that viruses can be genetically engineered to act as microscopic ...

If the third time is the charm, yet you botch that attempt just like the earlier two, then what? That's the problem facing NASA and its Space Elevator Challenge, which has for three successive years failed to live up to the vision of '2001'-author Arthur C. Clarke. Japan isn't waiting for a fourth, announcing plans to spend $7.3 billion on its own lift to whisk passengers (and cargo) 22,000 ...
