The glare that plagues watching television in otherwise pleasantly sunny rooms could soon become a thing of the past, thanks to the evolutionary prowess of a sunlight-shunning bug. Tapping the unique properties of moth eyes, a team of Fraunhofer Institute scientists may have figured out how to remove the annoying glare from all kinds of transparent plastic screens and other reflective products.
Rarely do the worlds of nanotech and carnival cuisine overlap, but when they do the results can be pretty sweet. A team of engineers has created a technology for fabricating nanofibers that's half high-speed centrifuge, half cotton candy machine, spinning and stretching out ultra-thin nanofibers that measure just 100 nanometers in diameter.
Miniaturization has been no small force driving computer technology forward over the past five decades, and a group of Australian researchers has proved just how small they think they can go. Using just seven atoms, scientists at the University of New South Wales working with researchers at the U. of Wisconsin have carefully constructed a quantum dot transistor, the smallest deliberately built electronic device in the world.
A collaboration between U.S. and South Korean researchers has produced what is thought to be the world’s smallest man-made pump, merely the size of a red blood corpuscle. More impressive still is their means of powering the pump, using glass – generally a very bad conductor of electricity – to craft an electrode at the nanoscale.
Nanotech has opened the door to some serious sci-fi possibilities: tiny robots -- built by other tiny robots -- that swim in our bloodstreams eradicating infection or hunting tumors, or perhaps assembling miniscule electronic components. But programming such tiny objects to do what we want presents a problem: commands need space to exist, and space is limited aboard a nanobot. But two papers just published in the journal Nature today highlight an interesting and promising approach to this problem: embedding the commands in the nanobots' environments.
Silicon chips are on the way out, at least if Duke University engineer Chris Dwyer has his way. The professor of electrical and computer engineering says a single grad student using the unique properties of DNA to coax circuits into assembling themselves could produce more logic circuits in a single day than the entire global silicon chip industry could produce in a month.
North Carolina State researchers have made a big breakthrough in data storage tech, and it's all thanks to some very tiny dots. Using nanodots – tiny nanoscale magnets – the team has manufactured chips that can hold an unprecedented amount of information using surprisingly little real estate. Each dot contains a single bit of data; a one square-inch chip can store over one billion pages of information.
IBM scientists working across three countries have created the smallest-ever 3D map of the world -- so tiny that 1,000 maps could fit on a grain of salt.
The map, measuring 22 by 11 micrometers, is scratched out on a polymer surface. Every 8 nanometers corresponds to 1,000 meters of altitude -- so Mount Everest would be about 64 nanometers high.
Nanotechnology's bright future has finally come up with a possible treatment for the dreaded pimples of our teen years. That has arrived in the form of gold nano-bombs which deliver a lethal dose of lauric acid to skin-dwelling bacteria responsible for that unsightly acne, according to UPI.

An innovative nanotech "vaccine" has been proven to cure type 1 diabetes in mice, and paves the way to do the same for humans. A dose of therapeutic nanoparticles given to diabetic mice restored healthy sugar levels in the rodents.
The nanoparticles making up the vaccine, thousands of times smaller than the cells they act on, are coated with protein fragments that suppress the autoimmune response that's characteristic of diabetes. Most importantly, unlike existing treatments for autoimmune disorders, the particles do all this without compromising the rest of the immune system.
