New method improves infrared imaging performance

February 8th, 2019
By successfully suppressing spectral cross-talk in dual-band photodetectors, a researchers has opened the door to a new generation of infrared imaging devices with applications in medicine as well as defense and security.

Researchers wing it in mimicking evolution to discover best shape for flight

January 29th, 2019
A team of mathematicians has determined the ideal wing shape for fast flapping flight -- a discovery that offers promise for better methods for harvesting energy from water as well as for enhancing air speed.

Feathers: Better than Velcro?

January 16th, 2019
The structures zipping together the barbs in bird feathers could provide a model for new adhesives and new aerospace materials, according to a new study. Researchers 3D printed models of the structures to better understand their properties.

Animals may get used to drones

January 15th, 2019
A new study shows that over time, bears get used to drones. Previous work indicated that animals behave fearfully or show a stress response near drone flights. Using heart monitors to gauge stress, however, researchers here found that bears habituated to drones over a 3 to 4-week period and remained habituated.

Using drones to tackle climate change

January 9th, 2019
Scientists are using drones to survey woody climbing plants and better understand how they may affect the carbon balance of tropical rainforests.

Engineers, zoologists reveal how gulls ‘wing morph’ for stable soaring

January 2nd, 2019
Aviation experts and zoologists have provided new insights into how gulls configure their wing shape -- known as wing morphing -- to stabilize their flight. The findings could be used to design more efficient flying vehicles, including soaring drones for farming or environmental monitoring.

Robots with sticky feet can climb up, down, and all around

December 19th, 2018
Researchers have created a micro-robot whose electroadhesive foot pads, inspired by the pads on a gecko's feet, allow it to climb on vertical and upside-down conductive surfaces, like the inside walls of a commercial jet engine. Groups of them could one day be used to inspect complicated machinery and detect safety issues sooner, while reducing maintenance costs.

The secret life of cloud droplets

December 19th, 2018
Do water droplets cluster inside clouds? Researchers confirm two decades of theory with an airborne imaging instrument.

Understanding dynamic stall at high speeds

December 18th, 2018
Although many fixed-wing aircraft can withstand similar rapid pitch-up maneuvers, a vehicle subject to this dynamic stall process is not reliably controllable. Motivated by the lack of detailed understanding, researchers took a deep dive into the physics of dynamic stall so that it can be used beneficially and reliably by aircraft.
