A new device using a laser-held bead has enabled the first direct measurement of pressure exerted by individual particles. Developed by researchers at Yale University, the tool could advance studies in extreme vacuums and help search for elusive particles like sterile neutrinos.

Undergraduate students at the University of Hamburg have constructed a simple cavity detector to search for axions, hypothetical particles that may constitute dark matter. Despite limited resources, their experiment set new limits on axion properties, as detailed in a recent study. The project demonstrates that small-scale efforts can contribute to major physics challenges.

An international team of researchers has detected signs of a rare η′-mesic nucleus, a fleeting particle trapped inside an atomic nucleus. This exotic state, observed in a high-precision experiment, suggests the η′ meson's mass decreases in dense nuclear matter. The finding could shed light on how matter acquires mass through the structure of space's vacuum.
