This New Incandescent Bulb Uses Nano Mirrors To Match LED Efficiency

Energy-saving bulbs may have some competition in the shape of an ageing technology. Scientists have developed a new kind of incandescent light bulb that uses modern science to ramp up its efficiency, almost matching that of commercial LED bulbs.


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 it got 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?


Gold Molecules Make Like A Snow-Blower To Carve Nano-Scale Pathways

These perfectly straight trenches were dug by molecules of gold. Under just the right conditions, gold will act like a mini-snow blower. It will pry molecules out of a material, puff away the detritus, and then move on to the next. One day, we could use this to make entire labs on a chip.


This Artist 'Paints' With Nanoparticles Inspired By Butterfly Wings

Combining art and science comes naturally to Kate Nichols. The colours 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.


These Images Are Only A Few Millionths Of An Inch Wide

A new printing method lets us make images smaller than we’ve ever before managed — much smaller than the width of the average human hair. What’s more, these images are in colour.


Our Future Space Elevator May Be Built Of Diamond

If the notion that humans will one day ascend into orbit on a rope of ultra strong carbon nanofibres sounds a bit out of this world, then you’re going to love the latest dazzling twist: our future space elevators might actually be built of diamond.


The First Ever Optical Rectenna Turns Light Directly Into DC Current

This fancy-looking slab is the world’s first optical rectenna, a small device that’s part antenna, part rectifier diode — and it’s able to convert light directly into DC current.


Robotic Microfish Can Sense And Remove Toxins From Their Environment

In the not-too-distant future, tiny robotic fish could be cruising around inside our our bodies, delivering drugs and cleaning up toxins. This week, engineers at the University of San Diego unveiled the first prototype: a chemically powered, magnetically controlled swimmer.


Scientists Can Now Make Nanoparticle Sheets That Curl Right Up

This isn’t a dirty, peeling sticker but a scientific first. Researchers have been able to make complex 2D and 3D structures using nanoparticles for years — but they have never before been able to curve or fold a flat sheet of them like this.
