Devices powered by taking a walk

Two engineers at the University of Wisconsin-Madison have developed a new energy-harvesting technology that they say can power a cellphone simply through walking.

Device screens act as solar chargers

Soon, devices such as phones and laptops could charge themselves thanks to displays that double as solar cells.

Self-assembling micro-robots can manipulate objects

Physicists at the US Department of Energy's (DOE) Argonne National Laboratory have  created tiny 'micro-robots' that can team up to form an assembly line.

Scientists build battery in a nanowire

Rice University researchers say they've been able to pack an entire lithium ion energy storage device into a single nanowire - as small as such devices could possibly get.

Applying the brakes with brain power alone

German researchers have used drivers' brain signals, for the first time, to assist in braking, providing much quicker reaction times, they say.

'Brain cap' turns thought into motion

A 'brain cap' being developed at the University of Maryland allows users to turn their thoughts into motion, potentially allowing them to control computers, robotic prosthetic limbs, motorized wheelchairs and even digital avatars.

'Jell-O' memory device works inside human body

Researchers from North Carolina State University have developed a soft, flexible memory device that can  function well in wet environments – perfect for electronic devices designed to work in and with the human body.

MIT grows LED array in a beaker

MIT's developed a way to grow an entire electronic device in a flask of liquid. The team demonstrated the technique, called hydrothermal synthesis, by producing a working LED array made of zinc oxide nanowires in a microfluidic channel.

Computer learns human language to teach itself to play games

MIT's developed a machine-learning system that allows a computer to read the instructions for playing Civilization - in one of several different languages - and improve its game.

Research brings more efficient spintronics

As the size of conventional transistors - as predicted by Moore's Law - rapidly approaches the theoretical minimum, Cambridge University physicists say they've made a major step forward in spintronics - a possible successor to the transistor.

New pen writes electrical circuits

There's a new way to create electric circuits that could be key to the creation of disposable electronic devices: write them with a pen.

HP moves closer to brain-like computing

Researchers at Hewlett Packard and UC Santa Barbara say they've made a breakthrough in the development of a device that could revolutionize computing by mimicking the brain.

New technology allows super-fast data transfer

3D movies could be downloaded to a smartphone in seconds with a new technology developed at the University of California, Berkeley.

Science bars redefine going out and partying

We all know that pubs and cafes have long been a breeding ground for new ideas and literary works of art, but could cafes be the new place for learning about... science?

U.S. students flunk Science 101

Embarrassing but hardly shocking: Less than half of U.S. students are currently proficient in science.

Team builds logic gates into bacteria

A team at the University of California has successfuly implanted E coli bacteria with the key molecular circuitry to act as computers.

Soldiers get lipo to meet Army weight requirements

If you thought that pills, yo-yo diets, and liposuction were relegated to the ladies of Hollywood, think again.

URI scientists to harness solar energy from pavement for practical use

The heat that pavement gives off is something everyone is familiar with. Researchers at the University of Rhode Island are exploring how this radiant heat energy can be used to melt ice, power streetlights, illuminate signs, heat buildings and generally make our lives better.
