Q&A: Berkeley Lab’s Spencer Klein Talks About IceCube Then and Now, and What’s Next

In this Q&A, Berkeley Lab physicist Spencer Klein, who has been a part of the IceCube collaboration since 2004, discusses Berkeley Lab’s historic contributions to IceCube, and IceCube’s contributions to science.

IceCube Neutrinos Point to Long-Sought Cosmic Ray Accelerator

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.

Berkeley Lab Team Wins Data-Driven Scavenger Hunt for Simulated Nuclear Materials

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.

CERN Ceremony Marks Groundbreaking for Accelerator Upgrade Involving U.S. National Labs

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 Space Dust: Berkeley Lab’s Extraterrestrial Research

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.

Supercomputers Provide New Window Into the Life and Death of a Neutron

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.

Underground Neutrino Experiment Could Provide Greater Clarity on Matter-Antimatter Imbalance

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.

Star Mergers: A New Test of Gravity, Dark Energy Theories

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.

A Flight Path to Physics Success

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.

The Mystery of the Star That Wouldn’t Die

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.
