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…
A chip designed to convert high voltages into lower levels in electronics — a process known as DC-DC step-down conversion — more efficiently using a piezoelectric resonator. Credit: UC San Diego Jacobs School of Engineering…

Phonon lasers are used to trap and levitate nanoparticles in the laboratory of Nick Vamivakas, the Marie C. Wilson and Joseph C. Wilson Professor of Optical Physics at the University of Rochester. Credit: University of…
Using a technique called multi-slice electron ptychography (MEP), researchers move a nanoscale-sized probe of electrons over a material and measure the resulting electron diffraction patterns. Overlapping regions can be used to create a 3D scan…
A new quantum battery prototype uses the strange rules of quantum physics to charge in a single rapid burst. Even more surprisingly, it charges faster as it gets larger, hinting at a radically different future…
Ultrathin 2D materials have long been seen as the key to pushing computer chips beyond current limits. But new research reveals a subtle, often overlooked factor that can quietly undermine their performance and reshape which…
A 532-nm continuous-wave laser “sculpted” microscopic patterns onto a flake of As2S3, including a monochromatic portrait of Albert Einstein (700-nm point spacing) and a QR-code-like design (600-nm point spacing). Credit: XPANCEO A team of scientists…
