An investigational implanted system being developed to translate brain signals toward control of assistive devices has allowed a woman with paralysis to accurately control a computer cursor at 2.7 years after implantation, providing a key demonstration that neural activity can be read out and converted into action for an unprecedented length of time.
Demonstrating an important milestone for the longevity and utility of implanted brain-computer interfaces, a woman with tetraplegia using the investigational BrainGate* system continued to control a computer cursor accurately through neural activity alone more than 1,000 days after receiving the BrainGate implant, according to a team of physicians, scientists, and engineers developing and testing the technology at Brown University, the Providence VA Medical Center, and Massachusetts General Hospital (MGH). Results from five consecutive days of device use surrounding her 1,000th day in the device trial appeared online March 24 in the Journal of Neural Engineering.
Expanding the power of thought: The implantable BrainGate neural interface can detect and record brain signals, allowing persons who have lost the use of arms and legs to have point-and-click control of a computer. A BrainGate device has remained functional for 

Untested nanoparticles showing up in thousands of consumer products

(NaturalNews) Since 2006, the use of nanoparticles in consumer products has skyrocketed by over 600 percent. Nanotechnologies, which involve the manipulation of elements and other matter on the atomic and molecular scale, are now used in over 1,300 commercial and consumer products. And that number is expected to jump nearly three-fold by 2020. But are these nanoparticles safe for humans and the environment, particularly when used in food-related applications?

According to data provided by the Project on Emerging Nanotechnologies (PEN), a group formed in 2005 for the purpose of “creat[ing] an active public and policy dialogue” on nanotechnology, nanoparticles are now used in everything from car batteries and appliances, to aluminum foil and non-stick cookware. The “Food and Beverage” section of PEN even includes various vitamin and mineral supplements that contain nanoparticles, as well as McDonald’s Read more…
