Even the nimblest of quadcopters still struggle to halt their lateral momentum when moving fast, limiting their maneuverability. An experimental drone addresses that problem in a bio-inspired fashion, by extending flying-squirrel-like membranous wings as needed.

Cranking up the air conditioner keeps buildings cool, but it guzzles energy. Passive materials can regulate temperatures more efficiently, and now scientists have developed a new coating that keeps glass much cooler, while still being transparent.

A new underwater robot can swim through the water with fins, and walk or crawl along the bottom when necessary. These capabilities could really give it a leg up – pun fully intended – at outperforming its traditional thruster-powered counterparts.

Mussels have long been known for the adhesive they produce, which allows them to cling to rocks. The protein responsible has now been utilized in a new skin grafting technique, which reportedly results in little to no scarring.

Researchers at the Pohang University of Science and Technology have created a miniature solid oxide fuel cell (SOFC) capable of powering drones for longer flight times, and which could be used to power everything from smartphones to cars in the not-too-distant future.

A material that has the strength and the lightness of titanium alloy and made from an amalgam of steel, aluminum, carbon, manganese, and nickel, has been developed that may see lightweight steel replace aluminum in lightweight, fuel-efficient automobiles and aircraft.
