Neurons Grow on Crosslinks of Carbon Nanotubes
Carbon nanotubes have a host of interesting properties. They are biocompatible and electrically conductive, so have been investigated as a possible material for growing nerve tissues. To make carbon nanotubes cooperate as desired, novel forms...

Wireless Brain Implant Controls Mice Using Drugs and Light
Optogenetics is a quickly evolving field that allows scientists to activate specific neurons using bursts of light. The technique may help to uncover the basis of neurological diseases and how to tame them. Using optogenetics to assess how...

Implanted Electrodes Improve Powered Prosthetic Arms
Today's conventional powered prosthetic arms usually have a few built-in electrodes that make contact with patient skin. These are good enough to open and close a simple claw, but for more nuanced control of prostheses with multiple degrees of...

World's Most Advanced Prosthetic Now With Sense of Touch
For prosthetic arms to really work well, they must have the ability to sense the things they're touching. The actions involved in grabbing a can of sardines, a fresh egg, or a plum at a grocery store are very different. The fingers of the hand...

Decoding Physical Patterns of Our Bodies via Conformable Devices: Interview with MIT's Canan Dagdeviren
Nature is full of physical patterns – from our breathing and the heart beating in our chests to the tides that lap the shore. The Conformable Decoders group at MIT believe that if such patterns can be “decoded,” they can provide a rich...

New Biomaterial Improves Brain Cancer Survival in Rats
Researchers from the University of Nottingham have developed a new biomaterial that delivers chemotherapies to treat brain cancer. Their work demonstrates that their biodegradable paste led to increased survival compared to controls, and that...

Generating Hallucinations Using Optogenetics
About a decade ago, Karl Deisseroth of Stanford University developed a technology called optogenetics. It allows scientists to stimulate individual nerve cells using light beams within the brains of live and moving animals. Now, this technology...

New Nanoparticles Help Spinal Cords to Heal Following Injury
When people damage their spinal cords, a lot of the long-term consequences often stem from the body's overreaction to the injury. That's because the blood-brain barrier protecting the spinal cord becomes compromised and overly aggressive immune...
