Using a video game in which people navigate through a virtual town delivering objects to specific locations, a team of neuroscientists from the University of Pennsylvania and Freiburg University has discovered how brain cells that encode spatial information form "geotags" for specific memories and are activated immediately before those memories are recalled.
Taking advantage of laser light's ability to gently push and pull microscopic particles, researchers have created what they're calling the world's smallest wrench.
MIT engineers say they've created a miniature device that can fold itself up into amost any shape, opening the way for cheap, reconfigurable robots.
The world's first thought-controlled robotic arm is due to be implanted in a patient this winter.
A proposed new center at Cambridge University will examine technologies, from biotechnology to artificial intelligence, that could perhaps threaten the future of our species.
Stanford researchers say they've designed the fastest, most accurate algorithm yet for brain-implantable prosthetic systems that let disabled people maneuver computer cursors with their thoughts.
Stanford scientists have for the first time created a synthetic material that can sense subtle pressure and heal itself when torn or cut.
Duke University scientists say they've succeeded for the first time in building a truly effective invisibility cloak.
For the first time, semiconductors have been produced from graphene - a potential revolution for the electronics market. The Norwegian developers say products could be on the market in as little as five years.
Scientists at the US Naval Research Laboratory are developing a process to extract carbon dioxide from seawater and use it to produce hydrogen gas, which can then be catalytically converted into jet fuel.
Scientists have discovered a new class of materials that could lead to improvements in computer memory.
Forget optical computing or quantum computing: researchers at Aalto University have successfully used water droplets as bits of digital information.
A new aerogel could be used for insulated clothing, refrigerators with thinner walls and building insulation, thanks to a series of breakthroughs.
Researchers at UC Santa Barbara have built a quantum processor that can factor a composite number - in this case the number 15 - into its constituent prime factors, 3 and 5.
To demonstrate that DNA's suitable for use as a large-scale data storage medium, a team of scientists has encoded a 5.27MB book using DNA microchips, and then read it back again.
Researchers at the Georgia Institute of Technology have worked out how to create tiny robots, just a few microns long, that can swim through liquids such as water and could one day be used for everything from drug delivery to construction.
UCLA researchers have developed a new transparent solar cell that could allow windows to generate electricity.
Human divers - and dolphins - could have a reprieve from searching out mines attached to ships' hulls, thanks to a new algorithm from MIT.
A new 'spintronic' organic light-emitting diode promises to be brighter, lower-cost and more environmentally friendly than those currently used in lighting, television and computer displays and other electronic devices.
US researchers have built what they say is the first set of robotic legs that walk just like a human being.
