A Nature study shows bright squeezed vacuum can drive nonlinear laser interactions far more efficiently, reducing the need for destructive intensity levels.

A German-led team has created and detected the long-predicted butterfly molecule, completing a 20-year search through a family of exotic ultralong-range Rydberg molecules.

A Wired science feature shows how simple household materials can be used to build a basic radio transmitter and receiver while explaining the physics of electromagnetic waves.

A Penn State graduate student presented new measurements of how Olympic barbells bend and recoil, offering a clearer look at the ‘whip’ lifters time during high-level competition.

Researchers have demonstrated tiny metasurface devices that can be pushed and directed by light, a step that could eventually help future light sails navigate through space.

A renewed look at David Bohm’s interpretation of quantum mechanics is reopening an old argument about whether the quantum world describes probabilities, hidden structure, or something closer to a concrete reality.

Researchers say a new error-mitigation approach called photon distillation can reduce noise before it derails calculations, potentially improving the path toward scalable photonic quantum computers.

Researchers have discovered three new kinds of ice in the past year, including two of the most complex yet observed, adding to a rapidly expanding map of water’s possible solid forms.

Researchers have produced an unusually careful new measurement of the gravitational constant, offering a potential path toward resolving the long-running mismatch between experiments.

A new mathematical model called QBox offers one possible picture of a world deeper than quantum theory, aimed at addressing physics where gravity and quantum mechanics still clash.

A large study highlighted by Gizmodo found that observations of the universe’s biggest structures remain consistent with Newtonian and Einsteinian gravity, weakening the case that modified gravity alone explains cosmolog

A new Universe Today explainer walks through the physics behind Cherenkov radiation by focusing on a deceptively simple question: why does light travel more slowly through matter than through vacuum?

A new Physical Review Letters study led by UC Riverside physicist Hai-Bo Yu argues that self-interacting dark matter could account for three long-running astrophysical puzzles across very different environments.

A new explainer revisits one of physics’ strangest asymmetries: the weak nuclear force only interacts with left-handed particles, a quirk that helps make radioactive decay, fusion, and stars possible.

A fresh retelling of Ettore Majorana's 1937 idea is drawing attention to one of modern physics' most persistent questions: whether neutrinos could be particles that are also their own antiparticles.

Physicist John Pendry, long known for the invisibility cloak, is now using metamaterial ideas to probe more ambitious territory, including materials that could simulate black-hole-like physics.

Two highly precise hydrogen experiments now agree with the smaller proton measurement that once shocked physics, strengthening the case that the particle’s radius is about 0.84 femtometres.

After years of anomalies and speculation, recent null results have pushed many physicists to conclude that the electron-volt sterile neutrino likely does not exist.

The Super Cryogenic Dark Matter Search experiment at SNOLAB has reached its ultra-cold operating temperature, allowing detectors to begin probing a new region of possible light dark matter signals.

After decades of stalled progress, researchers believe new mathematical tools are beginning to explain how the force that binds atomic nuclei together produces the massive particles that make up visible matter.
