Astronomers spot one of the largest spinning structures ever found in the Universe

December 4, 2025
Their findings, published in the Monthly Notices of the Royal Astronomical Society, could offer valuable new insights into how galaxies formed in the early Universe.Cosmic filaments are the largest known structures in the Universe: vast, thread-like formations of galaxies and dark matter that form a cosmic scaffolding. They also act as ‘highways’ along which matter and momentum flow into galaxies.

Scientists rule out fourth neutrino particle in search for new physics

December 4, 2025
An international team, including researchers from the University of Cambridge, working on the MicroBooNE experiment at the US Department of Energy’s Fermi National Accelerator Laboratory, has found no evidence of a long-suspected fourth type of neutrino, known as the ‘sterile neutrino’.Their results, published in the journal Nature, rule out the single sterile neutrino model with 95% certainty.Rul
