“In 2022, we were the first laboratory measurement to limit the neutrino mass to below an electron-volt. This limit will continue to be the most stringent as we improve our analysis and accumulate more data to understand the physical world better in the foreseeable future.”

Jacklyn Gates, a person with short dark hair wearing a black blazer over a green top.

“Superheavy elements are fascinating because they are incredibly rare and unstable, often existing for only fractions of a second before decaying. Studying these elements helps us unravel the mysteries of the periodic table, pushing the boundaries of our understanding of the fundamental building blocks of the universe.”

Benjamin Nachman, a person with short blonde hair wearing glasses and a gray collared shirt.

"Even though this work might not lead to practical applications in the near term, understanding the building blocks of nature is why we’re here – to seek the ultimate truth. These are steps to understanding at the most basic level what everything is made of. That is what drives me."

Experts at Berkeley Lab finished winding more than 2000 kilometers of superconducting wire into cables for new magnets that will help upgrade the Large Hadron Collider and the search for new physics. The magnets will be the most powerful of their kind and vastly increase the number of collisions in the LHC’s two general purpose detectors, ATLAS and CMS.

Berkeley Lab Project Scientist Jennifer Pore talks about how research in superheavy elements and isotopes can help us better understand the universe.

The beam on the left is filled with moving blue orbs and the beam on the right is filled with two larger orbs containing small galaxy depictions.
