US researchers refine ion engines that could make chemical rockets look obsolete
The big picture: In deep-space travel, the race is no longer about who has the biggest rocket – it's about who can build the smartest plasma engine. As the competition to reach Mars intensifies, engineers in the US, Russia, and China are accelerating development of propulsion systems that trade conventional fuel for charged particles and magnetic fields.
The technology could redefine how machines express emotion and interact with people
Something to look forward to: Inside a Columbia University engineering lab, a humanoid robot has learned to move its lips with previously unseen realism. The project, led by the Creative Machines Lab, represents the first time an autonomous system has acquired natural lip movement for speaking and singing through visual learning alone.
