Maze-solving automatons can repair broken circuits (w/ video)
Functioning brain follows famous sand pile model
One of the deep problems in understanding the brain is to understand how relatively simple computing units (the neurons), collectively perform extremely complex operations (thinking).
Access to electricity is linked to reduced sleep
Blame smartphone alerts, constant connectivity and a deluge of media for our society's sleep deprivation. But the root cause of why we get less sleep now than our ancestors did could come down to a much simpler ...

Renewable energy from evaporating water (w/ Video)
An immensely powerful yet invisible force pulls water from the earth to the top of the tallest redwood and delivers snow to the tops of the Himalayas. Yet despite the power of evaporating water, its potential ...
Scientists announce first room-temperature magnetic skyrmion bubbles
New ideas are bubbling up for more efficient computer memory.
New microfiber emitters boost production of versatile fibers fourfold, cut energy consumption by 92 percent
Nanofibers—polymer filaments only a couple of hundred nanometers in diameter—have a huge range of potential applications, from solar cells to water filtration to fuel cells. But so far, their high cost ...
In tuning friction to the point where it disappears, technique could boost development of nanomachines
Friction is all around us, working against the motion of tires on pavement, the scrawl of a pen across paper, and even the flow of proteins through the bloodstream. Whenever two surfaces come in contact, ...

This Slinky lookalike 'hyperlens' helps us see tiny objects
It looks like a Slinky suspended in motion.
Wearables may get boost from boron-infused graphene
A microsupercapacitor designed by scientists at Rice University that may find its way into personal and even wearable electronics is getting an upgrade. The laser-induced graphene device benefits greatly ...
A new way to measure friction between highly ordered pyrolytic graphite materials
Astronomers use space particles to measure electrical field in thunderstorms
Charged holes in graphene increase energy storage capacity
Engineers at the University of California, San Diego have discovered a method to increase the amount of electric charge that can be stored in graphene, a two-dimensional form of carbon. The research, published ...
