Even small objects can cause massive damage to fast-moving airplanes, aviation experts say, underscoring the inherent risks to pilots and passengers of collisions in the nation’s airspace after three ...

Active boundary heating and cooling can make a small object look much larger to thermal sensors, a step toward compact thermal camouflage and new ways to steer heat in devices. (Nanowerk Spotlight) ...

The future of imaging extremely small objects may come down to doughnut-shaped beams of light, according to a study from researchers at JILA and the Department of Physics. The study explored the ...

In a new study, researchers at CU Boulder have used doughnut-shaped beams of light to take detailed images of objects too tiny to view with traditional microscopes. The new technique could help ...

A new laser-based technique can create images of structures too tiny to view with traditional microscopes, and without damaging them. The approach could help scientists inspect nanoelectronics, ...
