Experiments at Berkeley Lab Help Trace Interstellar Dust Back to Solar System’s Formation

Experiments conducted at Berkeley Lab helped to confirm that samples of interplanetary particles – collected from Earth’s upper atmosphere and believed to originate from comets – contain dust leftover from the initial formation of the solar system.

Q&A: Berkeley Lab Physics Researcher Discusses New Higgs Boson Result

Jennet Dickinson, a graduate student researcher at Berkeley Lab and UC Berkeley, explains her role in a new particle physics result, announced today, that relates to the Higgs boson and it’s interaction with another particle, the top quark.

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.

Dozens of Photographers Attend Berkeley Lab’s Physics Photowalk

(Credit: Marilyn Chung/Berkeley Lab)   Dozens of photographers visited the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) on Wednesday, May 16 – coinciding with the International Day of Light – to creatively capture scenes of science at Lab facilities including the Advanced Light Source,

Early Career Spotlight: Zach Marshall Searches for Supersymmetry

Just five years after joining Berkeley Lab as a Physics Division fellow, Zach Marshall is co-leading an international team of researchers in search of supersymmetry — the theory that every known particle has a “superpartner” particle. Now with funding from an early career award announced last November, Marshall and his team are building a powerful super-scheduling platform that will help particle physicists process more data faster without investing in costly new computing infrastructure.

Tiny Distortions in Universe’s Oldest Light Reveal Clearer Picture of Strands in Cosmic Web

Scientists have decoded faint distortions in the patterns of the universe’s earliest light to map huge tubelike structures invisible to our eyes – known as filaments – that serve as superhighways for delivering matter to dense hubs such as galaxy clusters.

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.

Can Strongly Lensed Type Ia Supernovae Resolve One of Cosmology’s Biggest Controversies?

Astrophysicists at Lawrence Berkeley National Laboratory (Berkeley Lab) and the Institute of Cosmology and Gravitation at the University of Portsmouth in the U.K. say strongly lensed Type Ia supernovae could help resolve a discrepancy in measurements of the universe’s accelerating expansion.

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.
