From Belgrade to Berkeley: A Postdoctoral Researcher’s Path in Particle Physics

After completing her Ph.D. thesis in calculating the mass of the W boson – a heavier-than-iron elementary particle that mediates one of the universe’s fundamental forces – physics researcher Aleksandra Dimitrievska is now testing components at Berkeley Lab for a scheduled upgrade of the world’s largest particle detectors.

Solving the Dark Energy Mystery: A New Assignment for a 45-Year-Old Telescope

Today, the dome closes on the previous science chapters of the 4-meter Mayall Telescope in Arizona so that it can prepare for its new role in creating the largest 3-D map of the universe. This map could help to solve the mystery of dark energy, which is driving the accelerating expansion of the universe.

Creating a World of Make-Believe to Better Understand the Real Universe

Scientists are creating simulated universes – complete with dark matter mock-ups, computer-generated galaxies, quasi quasars, and pseudo supernovae – to better understand real-world observations.

How the Earth Stops High-Energy Neutrinos in Their Tracks

In an analysis of data from an experiment embedded in Antarctic ice, a research collaboration including scientists from Berkeley Lab has demonstrated that the Earth stops high-energy neutrinos – particles that only very rarely interact with matter.

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.

Berkeley Lab Intern Focuses on Using Light for Spaceflight

Elliot Heywood had dreamed of landing an internship at the science lab in the hills not far from his school in Lafayette, California, but he never could have imagined this dream would take wing as a summerlong stint researching an ultrafast interplanetary propulsion system. In May, after a friend and fellow high school senior at

Dark Matter Day Is Approaching … but Don’t Be Afraid of the Dark

A global hunt for the universe’s missing matter is underway, and this autumn everyone is invited to join in. On and around October 31, 2017, events around the world will celebrate the hunt for the universe’s unseen “dark matter.”

Berkeley Lab Intern Finds Her Way in Particle Physics

A Berkeley Lab intern is pursuing her passion in particle physics. Katie Dunne is designing circuit boards for the Atlas experiment at CERN.

Future Shines Bright for Space Science Intern Zachary Raha

Zachary Raha was the kind of kid who always had a side project. Today, Raha—who recently completed a Science Undergraduate Laboratory Internship (SULI) with Nobel laureate Saul Perlmutter of the Physics Division—keeps himself busy with maps of a different scale: the expansion history of the universe as illustrated by Type Ia supernovae.

New Measurements Suggest ‘Antineutrino Anomaly’ Fueled by Modeling Error

Results from a new study involving Berkeley Lab scientists could explain a mismatch between predictions and recent measurements of ghostly particles streaming from nuclear reactors—the so-called “reactor antineutrino anomaly” that has puzzled physicists since 2011.
