Lead Lab Selected for Next-Generation Cosmic Microwave Background Experiment

The largest collaborative undertaking yet to explore the relic light emitted by the infant universe has taken a step forward with the U.S. Department of Energy’s selection of Lawrence Berkeley National Laboratory (Berkeley Lab) to lead the partnership of national labs, universities, and other institutions that will carry out the DOE roles and responsibilities for the effort. This next-generation experiment, known as CMB-S4, or Cosmic Microwave Background Stage 4, is planned as a joint DOE and NSF project.

International Physicists Join Forces in Hunt for Sterile Neutrinos

An international group of more than 260 scientists has produced one of the most stringent tests to date for the existence of sterile neutrinos, which are theorized particles related to the three known types, or “flavors,” of neutrinos but that are not directly detectable.

Another Win for the Standard Model: New Study Defies Decades-Old ‘Discrepancy’ With High-Precision Measurement

A new study, led by a team of researchers including Berkeley Lab’s Josh McFayden, dives into a decades-old discrepancy in measurements relating to a Standard Model of particle physics pillar known as “lepton flavor universality,” and provides strong evidence to resolve it.

Natalie Roe Named Berkeley Lab’s Associate Director for Physical Sciences 

Natalie Roe, who joined Lawrence Berkeley National Laboratory (Berkeley Lab) as a postdoctoral fellow in 1989 and has served as Physics Division director since 2012, has been named the Lab’s Associate Laboratory Director (ALD) for the Physical Sciences Area. Her appointment was approved by the University of California today and was effective July 1, 2020. The announcement follows an international search. 

VIDEOS: Science Collaborations Find a Way During COVID-19 Pandemic

Even an underground experiment 4,600 feet below a mountain in Central Italy, and a telescope instrument more than a mile high atop an Arizona mountaintop could not escape the impacts of the COVID-19 pandemic. In these videos, a Berkeley Lab scientist and two Berkeley Lab-affiliated researchers share their experiences of working in international collaborations during the COVID-19 pandemic.

In International Physics Collaborations, Working Remotely Is Nothing New

Marjorie Shapiro, an experimental particle physicist and faculty senior scientist at Berkeley Lab, has been accustomed to working remotely and observing extreme social distancing from some colleagues for years, given that the scientific experiment she supports is 5,800 miles away.

Daya Bay Reactor Experiment Continues to Generate Data

Largely unaffected by the pandemic, the Daya Bay reactor neutrino experiment in Shenzen, China, has continued to pump data to remote supercomputers for analyses.

Site of LUX-ZEPLIN Dark Matter Search Project Carefully Ramps Up Science Work

The Sanford Underground Research Facility in South Dakota, which is home to the LUX-ZEPLIN dark matter search project, has begun a transition toward increased operations.

2 Berkeley Lab Scientists, Visiting Scientist Elected as New Members of Honorary Society

Two Berkeley Lab scientists and a visiting scientist are among the newest elected members of the American Academy of Arts and Sciences – a 240-year-old honorary society that recognizes accomplished scholars, scientists and artists in academia, the humanities, arts, business, and government.

Berkeley Lab Cosmologists Are Top Contenders in Machine Learning Challenge

In a machine learning challenge dubbed the 2020 Large Hadron Collider Olympics, a team of cosmologists from Berkeley Lab developed a code that best identified a mock signal hidden in simulated particle-collision data.
