Gravitational Waves and the Geometry of Spacetime
When talking about our universe, it is often said that “matter tells spacetime how to bend, and curved spacetime tells matter how to move.” This is the core of Albert Einstein’s famous general theory of relativity and describes how planets, stars and galaxies move and affect the space around them. While general relativity captures much…
Quantum Gravity Test: Simulating Gravity-Mediated Entanglement
Artist’s rendering of the implemented photonic experiment in which the coupling between polarizations of single photons is mediated by independent degrees of freedom of the photon path. In particular, mediated entanglement represents an essential principle of future experiments using massive particles, aiming to probe quantum gravity for the first time.

The importance of the paradise fish in evolutionary and behavioral genetics research
In Hungary, ethological research is most often identified with tests on dogs, but new methodological advances may bring another species, the paradise fish, into the spotlight. The fish are easy to handle and produce large numbers of offspring, which could open up new opportunities for researchers in the fields of evolution and behavioral genetics. Researchers…
New Study Confirms Germanium-71 Half-Life, Keeping the Gallium Anomaly Mystery Alive
The Search for the Elusive Neutrino Corresponding parts of the spectra obtained on day 20 of the three measurements performed. Credit: Physical examination C (2024). DOI: 10.1103/PhysRevC.109.055501 The Role of Gallium in Neutrino Experiments The search for the elusive neutrino takes many forms. Detectors composed of many tons of gallium are used in some experiments…
