Positronium shouldn't last long enough to be interesting. It's an "atom" assembled from an electron and its antimatter twin — ...

Discover how particle sizing with SPOS technology improves tail analysis, contamination control, and pharmaceutical quality ...

At high power, laser light inside a multimode optical fiber is supposed to misbehave. The beam usually breaks into a noisy, scattered pattern as the light ricochets through many paths at once.

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has ...

Alpha Centauri sits more than four light-years away, close enough to fascinate generations of dreamers and far enough to make ...

Advancements in structured illumination and computational imaging are revolutionizing semiconductor wafer inspection, ...

High-performance nanophotonic devices require extreme depth-to-diameter ratios, which are notoriously difficult to fabricate.

Abstract: Metasurfaces have attracted extensive attention due to their excellent capabilities in wavefront manipulation. However, chromatic aberration, which is widely present in phase-modulated ...

Scientists have made the first experimental observation of matter wave diffraction in a short-lived electron-positron atom.

Light has always carried more than brightness. In this case, it also carries direction and twist. That mix may open a new path for storing far more data in the same physical space. A research team led ...

Artemis II Commander Reid Wiseman peers back at Earth out of one of the Orion spacecraft's main cabin windows last Thursday. (NASA via AP) Editor's Note: This is an excerpt from WBUR's daily morning ...

A new breakthrough in wireless technology could dramatically boost internet speeds while cutting energy use—by switching from radio waves to light. Researchers have developed a tiny chip packed with ...
