Learn how expanding satellite megaconstellations in low Earth orbit could introduce widespread light pollution into space ...

Physicists have now managed to track the passage of time inside a quantum event without using anything that looks like a ...

The work, reported in Optica by scientists from Tianjin University and Nanyang Technological University, marks the first experimental realization of skyrmions that can be actively toggled ...

Auroras are nature’s most special light show: when charged particles from the sun hit our atmosphere, they can generate bright colors that dance across the night sky near the Earth’s poles. Auroras ...

It's the Super Bowl; would you have it any other way? The pass interference rule applies to both offensive players and defenders, and it's rather simple (if not always in application). According to ...

A new publication from Opto-Electronic Advances; DOI 10.29026/oea.2026.250149, discusses a quarter-wave geometric-phase route ...

A sensitive matter-wave interferometer measuring moiré fringes offers force sensitivity comparable to quantum interference ...

A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...

For more than a century, scientists have known that waves can behave in ways that seem to defy common sense, from freak walls of water in the open ocean to ghostly ripples inside atoms. What has ...

The 20th century was marked by the discovery of exotic states of matter. First, liquid helium was observed to flow without friction at extremely low temperatures, a phase now known as superfluid. Soon ...

A new metasurface lets scientists flip between ultra-stable light vortices, paving the way for tougher, smarter wireless communication.
