Crossing into a mirror world: Particles turn to wisps of fog, and the magnetic monopole paradox dissolves
In Goethe's ballad "Erlkönig," immortalized in Schubert's fevered 1815 setting, a dying boy riding through the night sees a spectral king beckoning from the darkness. His father calms him: "Mein Sohn, es ist ein Nebelstreif"—my ...

Tiny floating magnet detects ultrafaint magnetic fields at room temperature
Measuring faint magnetic fields is useful in a number of areas, including mapping brain activity, monitoring hearts and probing fundamental physics. Typically, picking up such weak signals requires expensive or bulky equipment, ...
XENONnT detector narrows the hunt for dark matter
Using a detector filled with nearly 9 metric tons of liquid xenon, researchers have delivered some of the most sensitive dark matter results ever recorded. In the latest analysis from the XENON collaboration, working at the ...
X(2370) emerges as glueball-dominated particle in collider experiments
At the International Conference on High Energy Physics in Brazil, the BESIII Collaboration report that, after 15 years of sustained research, it identified the dominant constituent of the X(2370) as a pseudoscalar glueball ...

Attosecond X-ray method maps early electron motions that trigger chemical reactions
All chemistry starts with a push from electrons. In the early moments of a chemical reaction, it's the movement of electrons that initiates the breaking of old chemical bonds and forging of new ones, transforming one molecule ...

Using the Earth's magnetic field to hunt for axions and dark photons
Dark matter's existence is all but certain—astronomers believe it makes up about a quarter of the universe's total energy content—yet its true identity has eluded us for decades. Two of the leading candidates for dark matter ...

First measurement of antineutrinos from spent nuclear fuel confirms emissions persist after reactor shutdown
Even when the lights go out and nuclear reactors are turned off, the story inside the reactor core still has a great deal to tell. Radioactive, long-lived fission products continue to decay for months or even years, producing ...

Bringing complex field physics to the tabletop: A photonic stage for non-Abelian gauge fields
For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain position, for example, it doesn't matter whether it's turned clockwise or counterclockwise—the result ...
Two attosecond flashes capture electrons in motion
Electronic motion sets the stage for virtually every light-induced process in nature, from the first step of a chemical reaction to the flow of charge in a solid. Yet these processes unfold so rapidly that they can be observed ...
