On Aug. 11, 2005, Rick Lind, a University of Florida assistant professor of aerospace engineering, examines a prototype of a tiny surveillance airplane that can change shape during flight. Mimicking seagulls, the plane’s wings can turn up, level out, and turn down, enabling it to become more agile or more stable as desired. The plane is a step toward tiny military drones that can soar over cities and dive between buildings to shoot surveillance photos, test for chemical or biological weapons or perform other tasks.
The military’s next generation of airborne drones won’t be just small and silent – they’ll also dive between buildings, zoom under overpasses and land on apartment balconies.
At least, that’s what University of Florida engineers are working toward.
Funded by the U.S. Air Force and NASA, UF aerospace engineers have built prototypes of 6-inch- to 2-foot- drones capable of squeezing in and out of tight spots in cities — like tiny urban stunt planes. Their secret: seagull-inspired wings that “morph,” or change shape, dramatically during flight, transforming the planes’ stability and agility at the touch of a button on the operator’s remote control.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.
"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...
In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.
A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...
By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
