New therapies are on the horizon for individuals paralyzed following spinal cord injury. The e-Dura implant can be applied directly to the spinal cord without causing damage and inflammation, scientists report. via Neuroprosthetics for paralysis: Biocompatible, flexible implant slips into the spinal cord — ScienceDaily.

In experiments using ultracold atoms and laser light, researchers have measured a stepwise change in conductivity as the atoms pass through tiny structures. This is the first time that this quantum effect has been observed for electrically neutral particles. via Quantum channel made of light — ScienceDaily.
