New Nanowire Batteries Can Be Charged More Than 100,000 Times

Li-on batteries gradually deteriorate as they’re repeatedly drained and recharged. But now researchers from University of California, Irvine have developed a new nano-wire battery that can survive hundreds of thousands of charging cycles.

These Microbots Steer Using Electricity and the Bacteria That Causes Urinary Tract Infections

Because the world keeps getting more bizarre, it turns out that the best way to get these microbots to navigate around obstacles is to smear them with the bacteria that causes urinary tract infections and send them through an electrical grid. See a demonstration!

Spider silk is nature’s Kevlar. It’s stronger than steel, it’s waterproof, and you can stretch it as much as 30 to 40 percent before it snaps. Now biophysicists at Johns Hopkins University think they know the secret to spider silk’s remarkable elasticity: protein threads that serve as stretchy “superstrings.” The researchers describe their work in a recent paper in the journal Nano Letters.

Scientists Made a Battery That Could Keep Hoverboards From Exploding

Hoverboards won’t stop exploding lately , perhaps due to overheating batteries. But what if the battery could shut off before all hot and flamey? That’s the idea behind recent research at Stanford, and the benefits go far beyond gimmicky gadgets looking to avoid recalls.

Scientists Build Tiny Microcannons That Fire Drug-Filled Nanobullets

The medical profession has long dreamed of an ideal delivery system for getting drugs to wherever in the body they’re needed most. Nanoscientists at the University of San Diego have come up with a novel means of doing so: why not fire the drugs at the intended targets, using tiny little cannons?

This Artist “Paints” With Nanoparticles Inspired by Butterfly Wings

Combining art and science comes naturally to Kate Nichols. The colors in her pieces don’t come from pigment, but from tiny silver nanoparticles suspended in the paint. She makes them herself, as artist-in resident in the University of California, Berkeley’s nanotechnology research group.
