Report: Memories are 'geotagged' with spatial information

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.

The evolution of Lego's female scientist

This is a testament to the growth of Lego as a company, or the fact that women are finally comfortable with having square, lumpy figures. Suck it, Heidi Klum. Everybody can't be a supermodel.

World's fastest movie camera to study atomic nuclei

If The Hobbit's 48 frames per second seems like a lot, how does a million trillion sound?

Wireless, broadband brain sensor created

Engineers at Brown University have developed a wireless, broadband fully implantable brain sensor that is rechargeable, and has performed well in animal models for more than a year.

Invasion of the telepathic rats?

Two rats thousands of miles apart have successfully communicated through thought alone to solve a series of problems.

Holographs harnessed for bionic eye

Israeli researchers are testing a holographic system designed to artificially stimulate cells in the eye, hoping to create a bionic system for restoring vision.

First 'true' quantum calculation performed

An international research group has for the first time demonstrated a quantum algorithm that performs a true calculation, without needing to know the answer before the start.

Team creates building block for quantum networks

Scientists say they've built a proof-of-concept device that could become the memory or processing element for an on-chip optical quantum network.

2D electronics come a step closer

Scientists say they've taken a big step toward the creation of two-dimensional electronics by combining a conductor and an insulator in layers just an atom thick.

Scientists store Shakespeare's sonnets in DNA

Scientists say they've found a comparatively error-free way to store data in DNA, and have already used it to encode Shakespeare's sonnets and MP3 music files.

New polymer harvests energy from water vapor

MIT engineers say they've found a way to generate electricity just by drawing on the water vapor in the air.

'World's smallest wrench' could help build solar sails

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.

'Transformer' robot can become almost anything

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.

Prosthetic arm is controlled by thought

The world's first thought-controlled robotic arm is due to be implanted in a patient this winter.

Cambridge center to study tech extinction risks

A proposed new center at Cambridge University will examine technologies, from biotechnology to artificial intelligence, that could perhaps threaten the future of our species.

Brain-controlled cursor sets record for accuracy

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.

Touch-sensitive plastic skin can heal itself

Stanford scientists have for the first time created a synthetic material that can sense subtle pressure and heal itself when torn or cut.

Researchers build 'perfect' invisibility cloak

Duke University scientists say they've succeeded for the first time in building a truly effective invisibility cloak.

Is graphene ready to replace silicon?

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.

Navy turns sea water into jet fuel

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.
