All-carbon solar cell harnesses infrared light

MIT – About 40 percent of the solar energy reaching Earth’s surface lies in the near-infrared region of the spectrum — energy that conventional silicon-based solar cells are unable to harness. But a new kind of all-carbon solar cell developed by MIT researchers could tap into that unused energy, opening up the possibility of combination …

Advances on Many Fronts to Spinal Cord Injury Repair

1. This image represents “copolymer micelles,” tiny drug-delivery spheres that could be used in a new approach for repairing damaged nerve fibers in spinal cord injuries. The bottom graphs show data indicating damaged spinal cord tissue recovered its “action potential,” or ability to transmit signals, after treatment with the micelles.
