In this illustration, light is coupled into a nanoscale cavity and interacts with an atomically thin material, creating exciton-polaritons. These hybrid particles combine light’s speed with matter’s ability to interact, enabling optical signal switching. Credit:…
Correlated photon pairs, generated via sunlight-pumped spontaneous parametric down-conversion in a nonlinear crystal, demonstrate ghost imaging. Credit: W. Zhang (Xiamen University) Scientists have shown that sunlight alone can generate quantum-correlated photons capable of producing “ghost…
An aerosol jet printer in Hersam’s laboratory deposits electronic inks onto a flexible polymer substrate. Credit: Mark Hersam/Northwestern University Printed artificial neurons can now send lifelike signals that activate real brain cells. This breakthrough could…
Small enough to fit in the palm of a hand, NASA’s High Performance Spaceflight Computing processor packs the power of a full system-on-a-chip. This next-generation processor is made to survive deep space while delivering a…

Artistic rendering of noncollinear sum-frequency generation (SFG): two infrared pulses mix in a χ² crystal to produce three output pulses (green), with the central SFG pulse being the primary output of interest. A neural network,…
AI symptom checkers are becoming a larger part of modern healthcare, but human psychology may limit their effectiveness in unexpected ways. Credit: Shutterstock Researchers found that distrust in AI causes people to give less detailed…
Under the right conditions, a chaotic mess of laser light can spontaneously self-organize into a highly focused “pencil beam.” This schematic shows the pencil beam formation mechanism. Credit: MIT MIT researchers found that chaotic laser…
