A step closer to self-aware machines

Columbia Engineers have created a robot that learns what it is, with zero prior knowledge of physics, geometry, or motor dynamics. Initially the robot has no clue what its shape is. After a brief period of ‘babbling,’ and within about a day of intensive computing, the robot creates […]

Space microbes aren’t so alien after all

A new Northwestern University study has found that — despite its seemingly harsh conditions — the ISS is not causing bacteria to mutate into dangerous, antibiotic-resistant superbugs. The bacteria are instead simply responding, and perhaps evolving, to survive in a stressful environment. Source: Space microbes aren’t so alien […]
