An international team of scientists has found the first evidence of a source of high-energy cosmic neutrinos, ghostly subatomic particles that can travel unhindered for billions of light years from the most extreme environments in the universe to Earth.
Competing in a fictitious high-stakes scenario, a group of scientists at Berkeley Lab bested two dozen other teams in a months-long, data-driven scavenger hunt for simulated radioactive materials in a virtual urban environment.
A groundbreaking ceremony today celebrates the start of civil engineering work for a major upgrade to the Large Hadron Collider at CERN in Geneva, Switzerland. When complete, the High-Luminosity LHC will produce five to seven times more proton-proton collisions than the currently operating LHC, powering new discoveries about our universe.
From moon rocks to meteorites, and from space dust to a dinosaur-destroying impact, the Department of Energy’s Berkeley Lab has a well-storied expertise in exploring samples of extraterrestrial origin.
A team led by Berkeley Lab researchers has enlisted powerful supercomputers to calculate a quantity, known as the “nucleon axial coupling” or gA, that is central to our understanding of a neutron’s lifetime.
Scientists working on the MAJORANA DEMONSTRATOR experiment have shown that they can shield a sensitive, scalable germanium detector array from background radioactivity – a critical step to developing a large experiment to study the nature of neutrinos and probe the universe’s matter-antimatter imbalance.
Observations and measurements of a neutron star merger have largely ruled out some theories relating to gravity and dark energy, and challenged a large class of theories.
In a previous career with the U.S. Air Force, Sandra Miarecki flew high above the Earth’s surface. She retired from the Air Force in 2007 to pursue a new calling in physics that would set her sights on particles traveling into the depths of the Earth.
Berkeley Lab and UC Berkeley scientists were part of a team that helped to decipher one of the most bizarre spectacles ever seen in the night sky: A supernova that refused to stop shining, remaining bright far longer than an ordinary stellar explosion. What caused the event is puzzling.
A fresh analysis of particle-collider data, co-led by Berkeley Lab physicists, limits some of the hiding places for one type of theorized particle – the dark photon, also known as the heavy photon – that was proposed to help explain the mystery of dark matter.
