What's powering these mysterious, bright blue cosmic flashes? Astronomers find a clue.

December 17, 2025

Among the more puzzling cosmic phenomena discovered over the past few decades are brief and very bright flashes of blue and ultraviolet light that gradually fade away, leaving behind faint X-ray and radio emissions. With slightly more than a dozen discovered so far, astronomers have debated whether they are produced by an unusual type of supernova or by interstellar gas falling into a black hole.

Analysis of the brightest such burst to date, discovered last year, shows that they’re neither.

Instead, a team of astronomers led by researchers from the University of California,...

UC Berkeley physicist John Clarke accepts Nobel Prize in Sweden

December 12, 2025

This year's Nobel Prize winners were invited to officially accept their awards from King Carl XVI Gustaf of Sweden in a special ceremony this week. UC Berkeley faculty John Clarke and Omar Yaghi were among this year's Nobel laureates, in addition to UC Berkeley alumni Michel Devoret and John Martinis. Among other festivities, the weeklong celebration featured lectures delivered by the Nobelists. John Clarke, Michel Devoret, and John Martinis were presented with the Nobel Prize in Physics "for the discovery of macroscopic quantum mechanical tunnelling and energy quantisation in an electric...

Quantum Nexus to Power California’s Research Regime

December 12, 2025

On October 3, proud alums were celebrating UC Berkeley’s past and present at Homecoming. Five floors up, campus and state leaders were hailing its future.

Governor Gavin Newsom, UC President James Milliken, and a bipartisan group of state legislators convened in Campbell Hall for the signing ceremony of Assembly Bill 940. The new law will accelerate quantum development in the state.

UC Berkeley mathematics professor awarded 2026 Joseph L. Doob Prize

December 8, 2025

The American Mathematical Society (AMS) awarded the 2026 Joseph L. Doob Prize to Maciej Zworski, UC Berkeley mathematics professor. Zworski shares this honor with Semyon Dyatlov (a former UC Berkeley faculty member), as the two are being honored for their 2019 AMS book, Mathematical Theory of Scattering Resonances. The Doob Prize recognizes "a single, relatively recent, outstanding research book that makes a seminal contribution to the research literature, reflects the highest standards of...

Most of the atomic clocks in the world — fewer than 500 in total — are housed at standards institutes and used to keep time for the planet. But the one inside UC Berkeley’s...

Building Bridges: Professor Lin Lin

October 29, 2025

Since 2014, Lin Lin has served as a computational mathematician in the Mathematics Department here at UC Berkeley, though he might also be a quantum chemist in disguise. By combining insights from both fields, he is interested in designing new algorithms that harness the power of quantum computers to tackle challenging problems in quantum chemistry and scientific computing more broadly.

Showing early on the tenacity we come to expect in successful scientists, Lin sought out difficult problems when he went from small-town eastern China to Peking University for...

Taking a Look Inside Brains: Professor Na Ji

October 17, 2025

Twenty years ago, Professor Na Ji (PhD in Chemistry ‘05) went through what she calls the grad student version of a mid-life crisis. “I just got a bit bored. You publish a few papers, but then it’s like, ‘What’s next?’” So she started picking up biology textbooks – molecular, developmental, and finally neurobiology. “They talk about current, voltage–they speak the language of physicists. Very quantitative. I basically decided that I want to become a neurobiologist.” Her renowned Physics advisor,...

University of California sets world record with five Nobel Prizes in one week

October 16, 2025

The University of California made history this week, as its faculty and alumni won five Nobel Prizes across medicine, physics and chemistry — the most ever awarded to a single institution in one year.

On Monday, Frederick Ramsdell, a UC San Diego and UCLA alumnus, shared the...
