At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same ...

Physicists have finally watched positronium, a short‑lived atom made of an electron and its antimatter twin, behave like a rippling quantum wave instead of a tiny billiard ball. In a set of ...

Light’s dual nature, manifesting as both wave-like and particle-like behaviour, is a phenomenon known as wave-particle duality and remains one of the most perplexing mysteries in quantum mechanics.

Since its development 100 years ago, quantum mechanics has revolutionized our understanding of nature, revealing a bizarre world in which an object can act like both waves and particles, and behave ...

Long before quantum mechanics existed, a scientist developed a powerful way of describing motion by drawing an analogy between particles and light.

New satellite-based analysis explains how energy carried by Alfvén waves moves from Earth’s magnetosphere into the atmosphere to generate auroral light emissions.

Electron beam oscillators utilising surface wave structures represent a key technology in the generation of high‐power electromagnetic radiation. By deploying relativistic electron beams in ...

The famed collider at Brookhaven National Laboratory has ended operations, but if all goes to plan, a new collider will rise ...

Photoionization mass spectrometry has transformed analytical chemistry, enabling complex chemical analysis and celebrating a century of scientific progress.

No one has ever probed a particle more stringently than this. In a new experiment, scientists measured a magnetic property of the electron more carefully than ever before, making the most precise ...
