Researchers at Berkeley Lab played a key role in an analysis of data from the world’s largest particle collider that found proof of rare, high-energy particle interactions in which matter was produced from light.
The Large Hadron Collider transforms matter into energy and then back into different forms of matter. But on rare occasions, it can skip the first step and collide pure energy – in the form of electromagnetic waves. Now, scientists have discovered particles of light merging and transforming into W bosons, confirming that at high enough energies, forces that seem separate in our everyday lives are united.
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.

The video was produced by Marilyn Sargent, a multimedia producer in the Strategic Communications department.
Inspired by the nation’s grappling with issues of race and racial discrimination, UC Berkeley physics major and Berkeley Lab student assistant Ana Lyons turned to art as a way to contribute to the conversation.
The Berkeley Lab-led center will forge the technological solutions needed to harness quantum information science for discoveries that benefit the world. It will also energize the nation’s research community to ensure U.S. leadership in quantum R&D and accelerate the transfer of technologies from the lab to the marketplace.
New research from Lawrence Berkeley National Laboratory shows that by the years 2045-2049 future temperatures will have more of an effect on when cool-season crops, such as broccoli and lettuce, can be grown than on where, while for warm-season crops (cantaloupe, tomatoes, carrots) the impact will be greater for where they can be grown versus when.
