Researchers have invented a new quantum holography technique that images objects using undetected light. This counterintuitive process, which involves two correlated beams of nonclassical light in an ...

For several centuries now, scientists have known that light behaves like a wave, expanding out from its source until absorbed or reflected by objects, which are in turn illuminated. In recent years, ...

Electrical and computer engineers have created a physical artificial neural network -- a device modeled on how the human brain works -- that can analyze large volumes of data and identify objects at ...

If you think X-rays and other forms of radiation have a monopoly on penetrating opaque objects, visible light begs to differ. It actually can pass through things like paint and human tissue, which has ...

With high-speed cameras you’re able to see bullets passing through objects, explosions in process, and other high-speed phenomena. Rarely, though, are you able to see what happens when light shines on ...
