A Flight Path to Physics Success

In a previous career with the U.S. Air Force, Sandra Miarecki of the Nuclear Science Division flew high above the Earth’s surface. She retired from the Air Force in 2007 to pursue a new calling in physics that would set her sights on particles traveling into the depths of the Earth. More>

How the Earth Stops High-Energy Neutrinos in Their Tracks

Neutrinos are abundant subatomic particles that are famous for passing through anything and everything, only very rarely interacting with matter. About 100 trillion neutrinos pass through your body every second. Now, scientists have demonstrated that the Earth stops energetic neutrinos — they do not go through everything. More>

Experiment Provides Deeper Look into the Nature of Neutrinos

The first glimpse of data from the full array of a deeply chilled particle detector operating beneath a mountain in Italy sets the most precise limits yet on where scientists might find a theorized process to help explain why there is more matter than antimatter in the universe. More>

Three Lab Researchers Elected as American Physical Society Fellows

Christian Bauer (Physics Division), Bill Collins (Earth and Environmental Sciences Area), and Ernst Paul Sichtermann (Nuclear Science Division) are among the recipients of 2017 APS fellowships. Lab-affiliated researchers who received fellowships via UC Berkeley include Daniel McKinsey and Yasunori Nomura (Physics Division), and Dan Kasen (Nuclear Science). Go here for a complete list of fellows and their citations.

Chasing Gamma Rays From Buenos Aires to Berkeley

For National Hispanic Heritage Month (Sept. 15 to Oct. 15) we recognize the contributions made and the important presence of Hispanic and Latino Americans and celebrate their heritage and culture. Today, read about Augusto Macchiavelli of the Nuclear Science Division, the second of three employees we will feature this week.

New 3-D Simulations Show How Galactic Centers Cool Their Jets

Scientists developed new theories and 3-D simulations to explain what’s at work in the mysterious jets of energy and matter beaming from the center of galaxies at nearly the speed of light. As much as half of the jets’ energy can escape in the form of X-rays and stronger forms of radiation. Two different mechanisms serve to reduce about half of the energy of these jets. More>

World’s Smallest Neutrino Detector Finds Big Physics Fingerprint

After more than a year of operation at Oak Ridge National Laboratory, the COHERENT experiment, using the world’s smallest neutrino detector, has found a big fingerprint of the elusive, electrically neutral particles that interact only weakly with matter. The international team of researchers included Berkeley Lab. The research was published in the journal Science. More>

Scientists Simulate Merger of Neutron Star and Black Hole

Lab scientists have developed new computer models to explore what happens when a black hole joins a neutron star, the superdense remnant of an exploded star. The simulations are intended to help detectors home in on the gravitational-wave signals. More>

The Fight to Rethink (and Reinvent) Nuclear Power

The latest in a series of Climate Lab videos produced by Vox Media and the University of California features the work of Berkeley Lab researcher Per Peterson. “When you look at how are we going to solve this problem of climate change, and ask how are we going to decarbonize? To not have nuclear energy on the table makes the job much harder,” he said. More>

Large Hadron Collider Kicks Off 2017 Season of Physics Research

In 2017, operators are hoping to produce the same number of collisions as in 2016, but over a shorter period, since the LHC started up a month later due to an extended year-end technical stop. Berkeley Lab researchers collaborate on ATLAS and ALICE, two among seven detector experiments at the LHC. More>
