Berkeley Lab Camera Can ‘See’ Sound

The Lab’s Carl Haber (Physics) and Earl Cornell (Engineering) are applying a technology they developed that uses a unique camera instead of phonographic needles to extract audio from century-old wax cylinder recordings of Native American speakers from around California. More>

Throwback Thursday…Through the Looking Glass in 1973

This photo shows John Kadyk of the Physics Division looking through the Electron Shower Detector for Stanford Positron Electron Accelerator Ring (SPEAR), taken in Building 51 on Jan. 22, 1973. An electromagnetic shower begins when a high-energy electron, positron or photon enters a material. More>

Construction on Mega-Science Neutrino Experiment Gets Underway

In a unique groundbreaking ceremony held July 21 at a research site in South Dakota, a group of dignitaries, scientists, and engineers from around the world marked the start of construction of a massive international experiment that could change our understanding of the universe. Berkeley Lab Project Management Officer Kem Robinson attended the event. More>

Physics Division Hosts High School Students, Teachers for Workshop

The group participated in the five-day workshop on “Physics in and Through Cosmology” last week. Presentations from Lab researchers covered such topics as cosmic rays and high-energy neutrinos, the ATLAS experiment, dark matter, dark energy, and the cosmic microwave background. Nobel-prize winner Saul Perlmutter also led a discussion.

Physics Matters for ATLAS Intern Katie Dunne

In high school, Katie Dunne dreamed of becoming a physicist but didn’t know anyone who worked in science. This summer, as a Berkeley Lab Undergraduate Research intern, she is working with her mentor Maurice Garcia-Sciveres to build prototype integrated circuit test systems for ATLAS as part of the High Luminosity Large Hadron Collider Project.

DESI, POLARBEAR/Simons Array Teams Gather at the Lab

Researchers with the Dark Energy Spectroscopic Instrument (DESI) collaboration and POLARBEAR/Simons Array collaboration met at the Lab to talk about technical progress on their respective projects. DESI seeks to create the largest 3-D map of the universe, while POLARBEAR is observing the most ancient light in the universe for hints of a period of rapid expansion. More>

Are We Living in a Giant Cosmic Void?

Voids, vast expanses of nearly empty space, account for about 80 percent of the observable universe. Researchers say the Milky Way may float near the center of one of these voids. The Lab’s Greg Aldering says the voids are “kind of like bubbles, they get bigger and bigger as the universe not only expands, but as more galaxies get pulled out over time.” More>

Former Lab Physicist Jerry Nelson Passes Away; Symposium Planned

Nelson was a pioneer in the design and development of segmented mirrors that enabled a new generation of large-scale telescopes. He died at his home in Santa Cruz on June 10. He was 73. A July 13-14 symposium that was already planned for Nelson, professor emeritus at UC Santa Cruz, will now serve as a memorial celebration. More>

Heavy Particles Get Caught Up in the Flow

New, high-precision measurements of the subatomic mix of particles produced by smashing gold nuclei together benefit from a Berkeley Lab-developed device known as the “Heavy Flavor Tracker.” The collisions free the quarks and gluons from their confinement within ordinary particles so their interactions, and the force that holds them together, can be studied by nuclear physicists.
