The recently commissioned MicroBooNE experiment at Fermi National Accelerator Laboratory has reached a major milestone: It detected its first neutrinos on Oct. 15, marking the beginning of detailed studies of these fundamental particles whose properties could be linked to dark matter, matter’s dominance over antimatter in the universe and the evolution of the entire cosmos since the Big Bang.
A team led by Oak Ridge National Laboratory computed distributions in calcium-48, and revealed that the difference between the radii of neutron and proton distributions (called the “neutron skin”) is considerably smaller than previously thought.
Today the MicroBooNE collaboration announced that it has seen its first neutrinos in the experiment's newly built detector, the first big step on its quest to spot the theorized fourth type of neutrino.
Researchers are sifting through an avalanche of data produced by one of the largest cosmological simulations ever performed, led by scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory. The simulation, run on the Titan supercomputer at DOE's Oak Ridge National Laboratory, modeled the evolution of the universe from just 50 million years after the Big Bang to the present day—from its earliest infancy to its current adulthood. Over the course of 13.8 billion years, the matter in the universe clumped together to form galaxies, stars and planets; but we’re not sure precisely how.
The 2015 Nobel Prize in physics was awarded today to Takaaki Kajita and Arthur B. McDonald for "the discovery of neutrino oscillations, which shows that neutrinos have mass." To help journalists and the public understand the context of this work, AIP has compiled a Physics Nobel Prize Resources page featuring relevant scientific papers and articles, quotes from experts and other resources. Seminal papers from the American Physical Society as well as coverage of that work in Physics Today and other relevant papers published by AIP Publishing have now been made freely available.
A newly upgraded high-power laser at the Department of Energy’s SLAC National Accelerator Laboratory will blaze new trails across many fields of science by recreating the universe’s most extreme conditions, such as those at the heart of stars and planets, in a lab.

The Fermi National Accelerator Laboratory announced that a 680-ton superconducting magnet is secure in its new home and nearly ready for a new era of discovery in particle physics.
To find out more about the elusive particles and their potential links to cosmic evolution, invisible dark matter and matter’s dominance over antimatter in the universe, the Department of Energy’s SLAC National Accelerator Laboratory is taking on key roles in four neutrino experiments: EXO, DUNE, MicroBooNE and ICARUS.
Today, the international Daya Bay Collaboration announces new findings on the measurements of neutrinos, paving the way forward for further neutrino research, and confirming that the Daya Bay neutrino experiment continues to be one to watch.

Scientists correlated atomic-scale defects in graphene with a “bucket brigade” style mechanism that lets protons travel through the graphene. Demonstrating such a mechanism and the prospect for gating it could enable directing proton pathways for improved fuel cells and other uses.
New data from the Relativistic Heavy Ion Collider confirm that small nuclei can create tiny droplets of a perfect liquid primordial soup when they collide with larger nuclei.
A study led by researchers from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and the University of California, Los Angeles has demonstrated a new, efficient way to accelerate positrons, the antimatter opposites of electrons. The method may help boost the energy and shrink the size of future linear particle colliders – powerful accelerators that could be used to unravel the properties of nature’s fundamental building blocks.
A school bus-sized detector packed with 170 tons of liquid argon has seen its first particle footprints.
