https://phys.org/physics-news/ en-us The Latest News from the Exciting World of Physics. Visit http://www.physicsfans.com For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but are increasingly prized for their technological potential. A third category discovered within the last decade may combine the best qualities of both. Dubbed altermagnets, they could someday help create faster, more energy-efficient electronics. https://phys.org/news/2026-05-diamond-quantum-sensor-reveal-elusive.html Condensed Matter Fri, 29 May 2026 15:20:02 EDT news699280720 A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line. https://phys.org/news/2026-05-icecube-cosmic-neutrino-spectrum-simple.html General Physics Fri, 29 May 2026 13:20:06 EDT news699105986 University of Calgary researchers are a part of a group who just got one step closer to solving a mystery of the universe.
