The pulse of an atom's magnetic heart as it ticks back and forth between quantum states has been timed in a laboratory. Physicists used a scanning tunneling microscope to observe electrons as they ...

The first-known observations of matter–antimatter asymmetry in a decaying composite subatomic particle that belongs to the baryon class are reported from the LHCb experiment located at the Large ...

Quantum mechanics describes the unconventional properties of subatomic particles, like their ability to exist in a superposition of multiple states, as popularized by the Schrödinger's cat analogy, ...

There's an issue with the RT Calculator Isotope program when running on certain versions of Windows. The application fails to start properly or crashes unexpectedly on launch, especially after recent ...

Reconciling space and time has been one of the most profound challenges in physics. One of the thorniest is how to stitch together the rules that steer subatomic particles and the rules that sculpt ...

Anomalous radio signals detected in Antarctica by the ANITA experiment were coming upward from Earth rather than down from the sky. Researchers used digital and mathematical simulations to test ...

In our daily lives, the sun seems constant and quiet, sedately shining at a steady pace. But looks can be deceiving: our star can also blast out powerful solar storms, huge explosions of energy and ...

In a bid to spot the elusive fundamental particle, the neutrino, a team of researchers from various universities and national laboratories in the US has tightened the limits on its existence and mass.

Physicists have placed a new limit on how big the elusive neutrino can be—one of the universe’s smallest known particles—a limit that makes other subatomic particles look as big as black holes by ...

This article takes a deep dive into the concept of mass, from atomic and molecular levels to subatomic particles, explaining how mass originates from the energy interactions of quarks, gluons and ...

The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

The isotope lead-208 was predicted to be extremely stable and perfectly spherical because of the “magic” numbers of electrons and protons orbiting its nucleus. When researchers blasted lead-208 with ...
