Researchers from the University of California at Berkeley have created a thin, chameleon-like material that can be made to change color — on demand — by applying a minute amount of force.

This week's Question: New virtual reality technologies were revealed at this month's Game Developers Conference in San Francisco, including the HTC Vive from game developer Valve Corporation and smartphone maker HTC. Vive uses lasers, sensors, and controllers to track motion in 3D space....

Biorobotics researchers at the Institut des Sciences du Mouvement (Aix Marseille University) have developed the BeeRotor, a tethered flying robot. The robot adjusts its speed and follows terrain without an accelerometer or the measurement of altitude.

Northumbria and Edinburgh Universities researchers have developed an innovative, new technique to harvest energy from carbon dioxide. The method may enable the creation of future power stations on the surface of Mars.The research proposes a new kind of engine for producing energy based...

This week's Question: Zero2infinity, a Spanish company, plans to launch passengers to near space using technologies called "Bloons." A maximum of four passengers will join two pilots in the Bloon cabin, which will be chained to a balloon filled with inert helium. Once fully inflated, the balloon will pull the cabin to...

Harvard School of Engineering and Applied Sciences researchers developed an ultra-thin, completely flat lens made of a glass substrate and tiny, light-concentrating silicon antennas. Color correction is achieved in the single, miniaturized device.

This week's Question: This month, the Federal Aviation Administration proposed long-awaited rules on the commercial use of small drones, requiring operators to be certified, fly only during daylight, and keep their aircraft in sight. The ruling, for now, prevents drones from being used for a range of possible...

To realize the "Internet of things” — the idea that all parts of the human environment, from kitchen appliances to industrial equipment, could be equipped with sensors and processors that exchange data — transmitters must be energy-efficient enough to last for months. A group researchers at the Massachusetts...

Researchers at the University of California, Riverside’s Bourns College of Engineering have developed a novel paper-like material for lithium-ion batteries. The spongelike silicon nanofibers are 100 times thinner than human hair. The technology could be used in batteries for electric vehicles...

This week's Question: Mars One, a group that plans to send humans on a one-way trip to Mars, has narrowed its application pool from 200,000 to 100. The finalists will spend the next decade in training, including team-building exercises and isolation. The goal of the Netherlands-based non-profit is to start a...

This week's Question: New apps, including one created by West Virginia University students in 2014, uses advanced facial recognition and liveness detection capabilities to authenticate smartphone users. A free technology from Hoyos Labs, showcased at this year’s Consumer Electronics Show in Las Vegas, similarly...

If selected for a NASA flight mission, the Ocean Radiometer for Carbon Assessment (ORCA) instrument will study microscopic phytoplankton, the tiny green plants that float in the upper layer of the ocean and make up the base of the marine food chain.
