Physicists propose that a long-overlooked, slow-decaying heavy neutrino shaped the early universe and may have left a signal in gravitational waves. The idea is a theoretical proposal and has not been confirmed by observation.
New research on bird flight finds that birds may not follow the landing path that physics would consider ideal for safety and energy use. The study examines why landing demands may have shaped how birds fly.
Scientists report detecting high-energy neutrinos arriving from distant cosmic sources, far more energetic than those from the Sun.
CERN scientists report new evidence that small atomic collisions at the Large Hadron Collider can recreate the state of matter that filled the early universe.
The 2026 Nobel Prize in Physics was announced on 6 October, and coverage has focused on the laureates and the research behind the award, including neutrino work at IceCube.
Giant neutrino detectors are being built a mile beneath the Black Hills to study why matter outlasted antimatter. Construction is described as starting on a Monday in a former gold mine.
The Neil Gehrels Swift Observatory, launched in November 2004, is in its final days in orbit and is expected to re-enter Earth's atmosphere this week.
French physicist Claude Cohen-Tannoudji, who shared the 1997 Nobel Prize in Physics, has died at 93.
A recent study suggests that primordial black holes formed in the early universe might experience an extra spatial dimension, offering new ways to search for them.
OpenAI reports AI-generated results on major problems in mathematics, computing and physics, and academic researchers will examine the work. Sam Altman has defended the effort while acknowledging it got out of control, and critics question the verification of the proofs.
An international team led by Queen's University Belfast researchers reports finding a population of Neptune Trojan asteroids that had eluded astronomers for decades.
New research suggests that water ice on the dwarf planet Ceres can mask massive surface salt deposits.
