Robot masters new skills through trial and error Posted: 22 May 2015 07:54 AM PDT Researchers have developed algorithms that enable robots to learn motor tasks through trial and error using a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence. |
Switching off brain circuit renders mice 'out of touch' with environment Posted: 21 May 2015 09:10 AM PDT New research suggests that the apparent simplicity of tactile sensation comes from a clever two-stage brain circuit. By manipulating this circuit with light-driven optical genetic tools, researchers made laboratory mice literally "lose touch" with their surroundings as their feet became unable to sense rough or smooth surfaces. |
