While neutrinos are some of the most abundant particles in the universe, they remain among the least understood. One of the biggest puzzles is their mass: although experiments have shown that neutrinos must have some mass, pinning down exactly how much has proven extraordinarily difficult. https://phys.org/news/2026-05-tritium-infused-graphene-sharpen-neutrino.html General Physics Tue, 19 May 2026 10:40:03 EDT news698400557 Despite being so elusive, neutrinos are produced in abundance in some of the most violent events in the universe. One of their strangest properties is that they can spontaneously switch between three types, or "flavors": a phenomenon known as neutrino oscillation that remains poorly understood in extreme astrophysical environments. https://phys.org/news/2026-05-neutrino-flavor-flips-key-triggering.html Astronomy Sun, 17 May 2026 08:40:03 EDT news697886203 If you could take an apple and break it into smaller and smaller parts, you would find molecules, then atoms, followed by subatomic particles like protons and the quarks and gluons that make them up. You might think you hit the bottom, but, according to string theorists, if you keep going to even smaller scales—about a billion billion times smaller than a proton—you will find more: tiny vibrating strings. https://phys.org/news/2026-05-theory-uniquely-derived-basic-assumptions.html General Physics Thu, 14 May 2026 12:26:29 EDT news697980361 When physicists fire beams of fast electrons at materials, they often need to know exactly how much energy those electrons will lose as they travel through. Through new research published in Physical Review Letters, a team led by Ke Jiang at Shenzhen Technology University in China has found that porous, mostly empty foam materials can stop high-current electron beams far more effectively than denser materials—overturning many previous assumptions about how these beams interact with solid materials. https://phys.org/news/2026-05-foam-overturns-assumptions-electron.html General Physics Wed, 13 May 2026 12:00:01 EDT news697886187 Matter behaves strangely under extreme conditions, and often, remnants of these behaviors are left behind even when conditions return to normal. The Trinity nuclear test in 1945 left behind such remnants, and now, 80 years after the explosion, researchers have identified another unique example of what happens when various materials are heated to temperatures exceeding 1,500 °C (2,730 °F) and put under pressures tens of thousands of times atmospheric pressure. https://phys.org/news/2026-05-years-trinity-nuclear-scientists-molecule.html General Physics Tue, 12 May 2026 12:50:01 EDT news697805584 Dark matter particles could be mediators of the interaction between electrons and atomic nuclei, as shown by a study conducted by junior group leader, Dr. Konstantin Gaul, Dr. Lei Cong, and Professor Dr. Dmitry Budker, of Johannes Gutenberg University Mainz (JGU), Helmholtz Institute Mainz (HIM) and the PRISMA++ Cluster of Excellence.
