You’ve probably heard of MechE alum and Associate Professor Hugh Herr (SM ’93), head of the Biomechatronics group at MIT Media Lab.
The TED Talk he gave earlier this year sparked a flurry of media...

Wind turbines across the globe are being made taller to capture more energy from the stronger winds that blow at greater heights.
But it’s not easy, or sometimes even economically feasible, to build...

The magnets cluttering the face of your refrigerator may one day be used as cooling agents, according to a new theory formulated by MIT researchers.
The theory describes the motion of magnons — quasi...

A new material structure developed at MIT generates steam by soaking up the sun.
The structure — a layer of graphite flakes and an underlying carbon foam — is a porous, insulating material structure...
