PhysicsSLAC's SPINE AI Reconstructs Neutrino Collisions Particle by Particle in Giant Argon Detectors
The machine-learning tool will analyze data from Fermilab's SBN program and the DUNE experiment, which is expected to start taking data in 2030.
PhysicsNew Calculation Closes the 20% Gallium Neutrino Gap Without Inventing a New Particle
Italian physicists say treating the electron and the nucleus together, instead of separately, makes a 30-year-old anomaly disappear. The work appears in Physical Review Letters.
PhysicsFrancis Halzen Wins Nobel Physics Prize for IceCube's Hunt for Ghost Particles
The 82-year-old Belgian-American physicist at the University of Wisconsin-Madison is honored for realizing that Antarctic ice could reveal high-energy neutrinos streaming in from distant galaxies.
PhysicsAstronomers Pin Down the Big Bang's Helium to 0.5%, Tightening the Test of Neutrino Families
A team measured 15 pristine galaxies over 130 hours at the Large Binocular Telescope. Their uncertainty is three times smaller than the previous standard.
PhysicsGhostly Neutrinos Switching Identity May Decide Whether a Dying Star Explodes
In 195 simulated star deaths, adding neutrino 'flavor' changes flipped many stars between 16 and 30 solar masses from supernovae to silent black holes, which could explain why astronomers see fewer explosions than expected.
PhysicsAstronomers Measured the Big Bang's Helium to Half a Percent
Using the Large Binocular Telescope to read helium lines in 48 metal-poor galaxies, the LBT Yp Project pinned the primordial helium fraction at 0.2458 ± 0.0013, cut the uncertainty from about 2% to nearly 0.5%, and found no room for a fourth neutrino in the universe's first seconds.
PhysicsA Dark Matter Detector Under an Italian Mountain Just Caught the Sun’s Faintest Neutrinos at 17,000 Electron Volts
XENONnT pushed the direct detection threshold for neutrinos lower than anyone has managed before. The signal comes from the proton-proton fusion that powers the Sun.
PhysicsMIT Says the Neutrino Laser Is Dead. Either of Two Reasons Would Have Killed It Alone
Wolfgang Ketterle's group worked through a 2025 proposal to build a coherent neutrino beam from a Bose-Einstein condensate. The recoil alone ends it, and then there is the problem of neutrinos being fermions.
PhysicsA Tank of Liquid Xenon Under an Italian Mountain Just Pushed Dark Matter Into the 'Neutrino Fog'
XENONnT found nothing — and that nothing is the tightest limit yet on axion-like particles and dark photons. It is the first detector to reach the boundary where the sun's own neutrinos start masquerading as a signal.
PhysicsA Detector in France Counted Ghost Particles Streaming Out of Nuclear Fuel That Had Already Been Switched Off
The Double Chooz experiment logged about 100 antineutrinos during 17 days when both reactors next door were shut down — the first measurement of its kind, and a possible new tool for catching cheating on nuclear treaties.
PhysicsScientists Build a Camera That Sees Invisible Particles in 3D — With as Few as Five Photons
A Swiss team's detector, called PLATON, could replace millions of tiny sensor components with a single block of light-producing material, using a light-field camera and AI to reconstruct particle tracks.
