When scientists compiled this data with signals picked up by multiple other instruments, like the Einstein Probe (EP) Wide-field X-ray Telescope and the Russian gamma-ray spectrometer, Konus-Wind, they found that they were dealing with the longest gamma ray burst (GRB) ever recorded. At around 25,000 seconds in duration (around seven hours), the GRB event scientists refer to as "GRB 250702B" beat out the prior record-holder, GRB 111209A, by 10,000 seconds. /news/2025-10-gamma-ray-black-hole-engulfed.html Astronomy Wed, 15 Oct 2025 06:50:01 EDT news679666733 Muon beams can now be created in a device that is the length of a ruler. /news/2025-10-compact-laser-plasma-generate-muons.html General Â鶹ÒùÔºics Plasma Â鶹ÒùÔºics Tue, 14 Oct 2025 13:40:01 EDT news679666717 Scientists at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) have discovered a way to control sound and vibrations using a concept inspired by "twistronics," a phenomenon originally developed for electronics. /news/2025-10-scientists-mechanical-vibrations-metamaterial.html Condensed Matter Optics & Photonics Mon, 13 Oct 2025 15:00:08 EDT news679309802 Dark matter, the substance that makes up about 27% of the universe, could potentially be detected as a red or blue light "fingerprint," new research shows.
