Researchers have broken the efficiency record for nuclear fusion on the micro-scale. Using an ultra-fast, high-powered laser, the results were about 500 times more efficient than previous experiments. The researchers blasted arrays of nanowires to create incredibly hot, dense plasmas.

Smartphone screens seem to crack at the slightest breeze, but researchers at the University of Sussex might have a hardier alternative. A new material made of graphene and silver could lead to touchscreens that are tougher, easy to manufacture, more responsive, less power-hungry, and even bend.

Researchers at Cambridge and the University of Warwick have jumped ahead to the logical endpoint of Moore's Law and shrunk wires down to a string of single atoms. Effectively one dimensional, these “extreme nanowires” are made of tellurium, compressed inside carbon nanotubes to keep them stable.

Engineers have tested a nano-system that could restore sight through a retinal implant that responds to light by directly stimulating the neurons that send visual signals to the brain. Unlike other systems, the new device requires no external sensors, and can provide a much higher resolution.

A nano-spacecraft made from a silicon chip could make the journey to Alpha Centauri in just 20 years. The problem is, such a "space-chip" wouldn’t survive the intense radiation and temperature of space, so a NASA and KAIST team is developing a method for helping the chip heal itself on the fly.

Researchers at the University of Central Florida have created a supercapcitor that can not only be fully-charged in mere seconds, but can go on to be recharged more than 30,000 times without affecting performance or capacity.

Imagine if instead of installing curtains or blinds, you could simply adjust the opacity of the glass in your windows. Well, that's how smart windows work. Researchers at Harvard University have now developed one of their own, which they say is simpler and cheaper than what's come before.
