Narrowing In on the W Boson Mass

Scientists working on the ATLAS experiment at the Large Hadron Collider (LHC)—the world’s largest particle collider, hosted at CERN, the European particle physics laboratory—have precisely measured the mass of the W boson, a particle that plays a weighty role in a delicate balancing act of the quantum universe.

From Belgrade to Berkeley: A Postdoctoral Researcher’s Path in Particle Physics

After completing her Ph.D. thesis in calculating the mass of the W boson – a heavier-than-iron elementary particle that mediates one of the universe’s fundamental forces – physics researcher Aleksandra Dimitrievska is now testing components at Berkeley Lab for a scheduled upgrade of the world’s largest particle detectors.

Creating a World of Make-Believe to Better Understand the Real Universe

Scientists are creating simulated universes – complete with dark matter mock-ups, computer-generated galaxies, quasi quasars, and pseudo supernovae – to better understand real-world observations.

Studying Gas Mask Filters So People Can Breathe Easier

Berkeley Lab scientists have been putting the X-ray spotlight on composite materials in respirators used by the military, police, and first responders, work that could eventually lead to better gas masks.

A Flight Path to Physics Success

In a previous career with the U.S. Air Force, Sandra Miarecki 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.

Berkeley Lab Takes Home Four R&D 100 Awards for Cutting-Edge Technologies

Technologies that help determine how solar energy affects the grid, benchmark energy savings for low-carbon cities, understand the functions of genes in microbes under different environmental conditions, and simulate how chemical reactions occur and change as fluids travel underground — all developed by researchers at Berkeley Lab — have received annual R&D 100 awards.

Screening for Disease or Toxins in a Drop of Blood

The promise of being able to quickly and accurately screen for diseases or chemical contaminants in a tiny drop of blood has long been an elusive goal. But scientist Daojing Wang says his company’s technology is up to the job.

The Puzzle to Plugging the Worst Natural Gas Release in History

By the time Berkeley Lab scientists Barry Freifeld and Curt Oldenburg visited the Aliso Canyon natural gas storage facility in December 2015, the SS-25 well blowout had been leaking natural gas into the air for more than six weeks. The notoriously strong winds at Aliso Canyon carried the natural gas and its added odorant to the nearby Porter Ranch neighborhood, leading to thousands of families evacuating their homes.

Reimagining Hydrogen: A Small Molecule With Large-Scale Ideas

While hydrogen is often talked about as a pollution-free fuel of the future, especially for use in fuel cell electric vehicles, hydrogen can be used for much more than zero-emission cars. In fact, from enhancing the flexibility of the grid to greening agriculture, hydrogen could play a major role in a clean and resilient energy system.

Berkeley Lab Tech Brings Nobel-Winning Cryo-EM Into Sharper Focus

Berkeley Lab played a key role in the 2017 Nobel Prize in chemistry, awarded today, honoring the development of cryo-EM, an imaging technique that has launched the fields of structural biology and biochemistry into an exciting new era of discovery.
