An international team of researchers has invented new artificial muscles strong enough to rotate objects a thousand times their own weight, but with the same flexibility of an elephant's trunk or octopus limbs.

 | A multidisciplinary team of researchers from UCLA, UC Merced, the Pennsylvania State University, Northwestern University, and Japan have observed single-molecule interactions of rotaxanes functioning in their native environment. The team, in research published in the journal ACS Nano, developed a molecular design that firmly attached rotaxanes to a surface, enabling them to be individually examined in their native environment by a scanning tunneling microscope. ...> Full Article |
Using neutron beams and atomic-force microscopes, a team of university researchers working with the National Institute of Standards and Technology may have resolved a 10-year-old question about an exotic class of "artificial muscles" -- how do they work? Their results could influence the design of future specialized robotic tools.

 | Surgeons from UC Davis Medical Center have demonstrated that artificial muscles can restore the ability of patients with facial paralysis to blink, a development that could benefit the thousands of people each year who no longer are able to close their eyelids due to combat-related injuries, stroke, nerve injury or facial surgery. ...> Full Article |
 | BioInterfaces represents an ambitious new "Key Technologies" research program supported by the Helmholtz Association, the largest German scientific funding organization. The program brings together a team of biologists, chemists, physicists, materials scientists and informaticians. With an annual budget of approximately 20 million euro ($27.6 million), the 67 research teams will work closely together to develop innovative tools and technologies for precisely controlling the behavior of cells. ...> Full Article |
Soft and tough like biological tissue: DNA-wrapped carbon nanotubes

Northwestern University researchers have shown that it could be possible to control a limb by stimulating groups of muscles rather than individual muscles -- a finding that could be useful in future treatments of paralysis patients. The research team used a model of the muscles in a frog's hind leg to perform a computational analysis that shows researchers can control the limb using muscle groups just about as well as if they controlled individual muscles.

Researchers have demonstrated for the first time that a direct artificial connection from the brain to muscles can restore voluntary movement in monkeys whose arms have been temporarily anesthetized.
