Carbon nanotube film restores light sensitivity to blind retinas | Science technology and reaserch | Scoop.it
(Phys.org) —Light striking the retina in the back of the eye is the first major step in the vision process. But when the photoreceptors in the retina degenerate, as occurs in macular degeneration, the retina no longer responds to light, and the person loses some or all of their sight. However, if ...

Enabling biocircuits: New device could make large biological circuits practical

Enabling biocircuits: New device could make large biological circuits practical | Science technology and reaserch | Scoop.it
Researchers have made great progress in recent years in the design and creation of biological circuits -- systems that, like electronic circuits, can take a number of different inputs and deliver a particular kind of output. But while individual components of such biological circuits can have precise and predictable responses, those outcomes become less predictable as more such elements are combined. Scientists have now come up with a way of greatly reducing that unpredictability, introducing a device that could ultimately allow such circuits to behave nearly as predictably as their electronic counterparts.
