Reinforcement learning expedites 'tuning' of robotic prosthetics

Researchers have developed an intelligent system for ‘tuning’ powered prosthetic knees, allowing patients to walk comfortably with the prosthetic device in minutes, rather than the hours necessary if the device is tuned by a trained clinical practitioner. The system is the first to rely solely on reinforcement learning to tune the robotic prosthesis.

Puzzling phenomenon in a quantum gas: Insulators with conducting edges

Insulators that are conducting at their edges hold promise for interesting technological applications. However, until now their characteristics have not been fully understood. Physicists have now modeled what are known as topological insulators with the help of ultracold quantum gases. They now demonstrate how the edge states could be experimentally detected.
