In this Q&A, Particle Physics and Astrophysics Professor Lance Dixon of Stanford University and the Department of Energy’s SLAC National Accelerator Laboratory explains one approach to developing such a theory, called quantum gravity.
Researchers used a powerful, custom-built X-ray microscope at the Department of Energy's SLAC National Accelerator Laboratory to directly observe the magnetic version of a soliton, a type of wave that can travel without resistance. Scientists are exploring whether such magnetic waves can be used to carry and store information in a new, more efficient form of computer memory that requires less energy and generates less heat.
A new space telescope will soon peer into the darkness of 'near space' (within a few thousand light years of Earth) to seek answers related to the field of high-energy astrophysics.
Members of Fermilab's Technical Division recently achieved a record-high quality factor with a fully dressed cavity for a SLAC-headed project, Linac Coherent Light Source II.
Peering at the debris from particle collisions that recreate the conditions of the very early universe, scientists have for the first time measured the force of interaction between pairs of antiprotons. Like the force that holds ordinary protons together within the nuclei of atoms, the force between antiprotons is attractive and strong. The experiments were conducted at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory and will publish in Nature.
To help tackle the considerable challenge of interpreting data, researchers from the U.S. Department of Energy's (DOE's) Argonne National Laboratory are demonstrating the potential of simulating collision events with Mira, a 10-petaflops IBM Blue Gene/Q supercomputer at the Argonne Leadership Computing Facility (ALCF), a DOE Office of Science User Facility.
To uncover the secrets of neutrinos, scientists build massive detectors to help them spot these elusive particles. The latest, dubbed MicroBooNE, recently spotted its first accelerator-born neutrino event candidates at Fermi National Accelerator Laboratory. Scientists from nearly 30 institutions, including the US Department of Energy's Brookhaven National Laboratory, collaborate on this experiment.
Nestled inside the massive MicroBooNE detector, part of a new neutrino experiment just getting underway at the U.S. Department of Energy's (DOE) Fermi National Accelerator Laboratory, lie 50 circuit boards packed with custom-built microelectronics. These circuits were designed by engineers at DOE's Brookhaven National Laboratory to operate while immersed in liquid argon, a cryogenic liquid that boils at a biting -186 degrees Celsius or -303 degrees Fahrenheit.
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.
