DOE 40th Anniversary Milestone: Expansion of Universe is Speeding Up

Scientists assumed the universe’s expansion was slowing down as gravity pulled debris from the Big Bang back together. But in 1999 Saul Perlmutter and others discovered the universe’s expansion is speeding up, driven by an unknown cause referred to as “dark energy.” They used measurements from Type 1a supernovae, which all reach maximum brightness when they explode.

DOE’s 40 Years of Research: When the ‘Big Bang’ Became a Household Phrase

In this latest installment of the Department of Energy’s 40th anniversary celebration, the Office of Science commemorates astrophysicist George Smoot’s landmark 1992 paper, “Structure in the COBE Differential Microwave Radiometer First-Year Maps,” which presented a monumental discovery that won the 2006 Nobel Prize in physics and turned the Big Bang into a household phrase.

Story Highlights Oliver-Mallory’s Work at the Sanford Underground Lab

Kelsey Oliver-Mallory’s first few cage rides to the 4850 Level “felt like an adventure,” she said. Now, her trip to the Black Hills State University Underground Campus where she works in the low-background counting facility has become routine. But she still loves going to work there. Oliver-Mallory is a UC Berkeley graduate student working in the Lab’s Physics Division. More>

ATLAS Sees First Direct Evidence of Light-By-Light Scattering at High Energy

Physicists from the ATLAS experiment at CERN have found the first direct evidence of high energy light-by-light scattering, a very rare process in which two photons interact and change direction. The Lab is among the collaborators for the Large Hadron Collider’s ATLAS detector and has a dedicated ATLAS team through the Physics Division. More>

Special Series Highlights the Lab’s Summer Interns

All this week, the experiences of students and faculty who worked on big science at Berkeley Lab over the summer will be presented via feature videos, Instagram takeovers, and articles. Visit Today at Berkeley Lab and follow @BerkeleyLab on Twitter, Instagram, and Facebook to learn how an internship at Berkeley Lab can help steer a student’s career in STEM fields. In today’s video, we focus on Anya Nugent, a physics major from Hamilton College who participated in the Berkeley Lab Undergraduate Research program under the supervision of Shirley Ho and Zachary Slepian in the Physics Division.
