Technology

Gallium: The liquid metal that could transform soft electronics

Bend it. Stretch it. Use it to conduct electricity. Researchers are exploring a range of applications that harness the element’s unusual properties.

A short repeating movie clip shows a cyclist riding down a bike path in the dark; the path glows green.
Technology

Will glow-in-the-dark materials someday light our cities?

Substances that persistently luminesce are already used in some bike lanes, and in the future could be applied to sidewalks, streets and buildings — saving energy and reducing urban heat

Stylized drawings of a real nerve cell and an electronic version that can also process and store information.
Technology

Making computer chips act more like brain cells

Flexible organic circuits that mimic biological neurons could increase processing speed and might someday hook right into your head

Animation shows a close-up of the moving robotic arm of the OSAM-1 spacecraft.
Technology

Orbiting robots could help fix and fuel satellites in space

Machines that grip, grapple and maneuver will soon have their go at maintaining the fleet of small spacecraft that encircle Earth

A collage of photos shows five high-rise buildings made of mass timber.
Technology

Sustainable building effort reaches new heights with wooden skyscrapers

Wood engineered for strength and safety offers architects an alternative to carbon-intensive steel and concrete

Six different robots for underground use
Technology

Deep underground, robotic teamwork saves the day

Deploying a motley crew of robots that can roll, walk and fly is a smart strategy for search-and-rescue operations — and so is trusting the machines to make decisions on the ground

A GIF shows the looping flight of a SkySails paraglider-type red kite as it generates electricity.
Technology

Could high-flying kites power your home?

Nearly a dozen companies are betting on computer-controlled, airborne wind energy to electrify the future
