Technology & Engineering

Technology and Engineering bridge the gap between what the mind can imagine and what the laws of nature allow. While scientists seek to discover what is not yet known, engineers apply fundamental science to design and develop new devices and systems—technology—to solve societal problems. Technological and engineering innovations then return the favor by affecting human—as well as other animal species'—the ability to control and adapt to their natural environments.

Nanotechnology: powerful solutions

Paul Alivisatos' team at the University of California, Berkeley, is working to develop a new type of solar cell using nano-sized crystals called quantum dots.

Cell-ular reception

Sharpen your minds as the pointy pencils of "The Fast Draw" provide a primer on the awesome science and engineering behind one of the most game-changing advances in the last decade.

Are invisibility cloaks possible?

Have you ever wished you could hide under an invisibility cloak like Harry Potter or conceal your car with a Klingon cloaking device like in "Star Trek"?

How do you feel? Video of your face may tell all

Researchers are developing a highly accurate, touch-free system that uses a video camera to monitor patients' vital signs just by looking at their faces. The technique isn't new, but engineering researchers are making it work under conditions that have so far stumped earlier systems.

Computers that see, hear and think like humans

A multidisciplinary research and education center at the University of Maryland is developing computer systems that can replicate human sensory skills like eyesight, hearing and perception.
