New spinning drone hides in plain sight: 'Phantom Twist' harnesses motion blur to nearly vanish in flight

By exploiting the quirks of human vision, Northwestern University engineers have designed a drone that nearly disappears before the eyes. For years, researchers have tried to design invisible drones and robots using camouflage, ...

Engineers develop robot that judges its surroundings and walks, runs, and jumps like an animal

An era in which robots decide "how to walk" on their own has arrived. A four-legged robot has been developed that, much like a person or an animal, autonomously chooses the appropriate gait strategy for its surroundings—changing ...

Researchers mimicked bird bones to create lightweight, high-performance structures

Using bird bone structure as inspiration, Xin Ning and Sepideh Ebad Sichani, Ph.D. '26, have created a new class of aircraft wing structures—unbound by traditional designs of ribs, spars and stiffeners. The researchers are ...

Sand could be key to safer, stronger structures

Engineers have been working for centuries to protect buildings, bridges and other structures from damage caused by severe weather and natural hazards, but one of the best methods may begin with sand, according to a newly ...

Holographic printer produces 3D shapes in one shot

University of Utah researchers have demonstrated a new method of 3D printing that avoids the leaky seams that come with the layer-by-layer process. Using a nanoscale "mask" that diffracts laser light into a holographic pattern ...
