Using computers to view the unseen

Cameras and computers together can conquer some seriously stunning feats. Giving computers vision has helped us fight wildfires in California, understand complex and treacherous roads — and even see around corners.  Specifically, seven years ago a group of MIT researchers created a new imaging system that used floors, doors, and …

Helping machines perceive some laws of physics

Humans have an early understanding of the laws of physical reality. Infants, for instance, hold expectations for how objects should move and interact with each other, and will show surprise when they do something unexpected, such as disappearing in a sleight-of-hand magic trick. Now MIT researchers have designed a model …

Toward more efficient computing, with magnetic waves

MIT researchers have devised a novel circuit design that enables precise control of computing with magnetic waves — with no electricity needed. The advance takes a step toward practical magnetic-based devices, which have the potential to compute far more efficiently than electronics. Classical computers rely on massive amounts of electricity …

Autonomous system improves environmental sampling at sea

An autonomous robotic system invented by researchers at MIT and the Woods Hole Oceanographic Institution (WHOI) efficiently sniffs out the most scientifically interesting — but hard-to-find — sampling spots in vast, unexplored waters. Environmental scientists are often interested in gathering samples at the most interesting locations, or “maxima,” in an environment. …
