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 ...

Turns out the key to making things lighter than air is…light! California scientists think they’ve found a way to make objects levitate using concentrated light — a theory that could even propel ...

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, ...

Breakthroughs, discoveries, and DIY tips sent every weekday. Terms of Service and Privacy Policy. Back in 2018, astronomers examining the ruins of two collided ...

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 ...

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 ...

Princeton researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical ...

Although we've seen color-changing coatings before, they generally just switch between two solid colors. MIT scientists have developed a new system, however, that allows coated objects to take on ...

Once thought of as the province of only "Star Trek" or "Harry Potter," cloaking technologies could become a reality with a specially designed material that can mask itself from other forms of light ...

Researchers have uncovered new rules governing how objects absorb and emit light, fine-tuning scientists' control over light and boosting research into next-generation solar and optical devices.
