Wireless checkout is many a grocer’s dream. It’s like Amazon’s one-click shopping in the real world, maximizing efficiency for the customer and cutting costs for the supermarket. A new printable RFID tag could make it a reality. More

As concerned as we are about memory , we haven’t done much to preserve it. Most of our hard drives don’t last past 30 years. But soon, using diamond-like carbon nanotubes , even your Gizmodo comments could last practically forever

Laser-powered carbon nanotube speakers! They’ll fit in walls and windows, and can noise-cancel ambient rackets. Or blast some music. More

We often speak of material being used to conduct electricity , but what if underwear makers AussieBum—who’ve created underpants made from banana fiber—used carbon nanotubes as well? Think of the possibilities banana-derived electricity-conducting pants could bring you.

Johnny Cash can’t have known about carbon nanotubes when he sang about rings of fire, but MIT scientists have shown how they can create electrical current—about 100 times as much energy per unit of weight as lithium-ion batteries. The new experiments involved nanotubes, or submicroscopic structures just a few billionths of a meter in diameter, that can conduct both electricity and heat. Engineers coated the nanotubes with reactive fuel that produces heat by decomposing, and then ignited it with laser beams or high-voltage sparks.

A bacterium on its own can’t reach very far. And when stacked on the sea floor in a large colony, it may have access to either oxygen (top of the pile) or food (bottom of the pile). So for the entire colony to thrive, the bottom and top layers must be choreographed in chemical reactions occurring across great expanses, allowing electrons from food consumption in the basement to react to oxygen from the rooftop

Nanotech wonder Buckypaper is 10 times lighter and 500 times stronger than steel. And while academic research labs have successfully synthesized the stuff for years, the first architectural firm has just made Buckypaper on their own. NY’s Decker Yeardon just revealed their first thin sheet of the stuff—a “paper” made up of carbon nanotubes that, aside from being absurdly strong and light, can serve functions like filtering and heat dispersion
