Cara Brook’s shot in the dark

December 10, 2025

Bats carry many of the world’s most virulent human viruses: rabies, Ebola, Marburg, Nipah, and Hendra. In the wake of COVID-19 (and its bat-borne virus, SARS-CoV-2), scientists are searching for why these viruses manifest so dangerously in humans.

Rescuing Reefs from the Inside Out

December 10, 2025

Phillip Cleves is looking forward to finishing his lab’s renovations in February so he can finally invite his fellow professors over to enjoy cold liquid running straight from the tap: fresh, artificial seawater.

Crews are currently installing pipes in Koshland Hall to service the six 200-gallon coral tanks and 600 anemone racks that will occupy his new lab. All told, Cleves will be able to create 1,000 gallons of...

Berkeley wants more people to be CURED

December 10, 2025

UC Berkeley is embarking on a new approach to advance medicine and global health. The Center for Unmet, Rare, and Emerging Diseases (CURED) will unite researchers across campus to find cures that other organizations are not pursuing.

Pharmaceutical companies seek a return on their investments. Medical schools and research centers require nearby patients. But what happens if a disease is new, uncommon, or concentrated...

All life copies DNA unambiguously into proteins. Archaea may be the exception.

December 5, 2025

A study finds that one microbe, a member of the Archaea, tolerates a little flexibility in interpreting the genetic code, contradicting a 60-year-old doctrine.

The beauty of the DNA code is that organisms interpret it unambiguously. Each three-letter nucleotide sequence, or codon, in a gene codes for a unique amino acid that’s added to a chain of amino acids to make a protein...

UC Berkeley dean’s research inspires emerging treatment for rare bone disease

November 21, 2025
Regeneron Pharmaceuticals, Inc. announced on September 17 that it had completed a phase 3 trial for a drug to treat fibrodysplasia ossificans progressiva (FOP). FOP is a severe, ultra-rare genetic disorder that forms bone in connective tissues, which may significantly restrict mobility and result in an early death. Regeneron’s trial medicine reduced new bone lesions in FOP patients by over 90 percent. After announcing the positive news, Aris Economides, vice president of research at Regeneron, shared his excitement with UC Berkeley’s dean of biological sciences, Richard Harland. It was Harland’s mid-1990s discovery of a gene and its associated protein that prompted Regeneron down a winding path that eventually led to its potential FOP treatment — a demonstration of basic research’s value to society.

“Action is my coping mechanism”: Wendy Marie Ingram on building community care in academia

November 13, 2025

“Action is my coping mechanism,” says Wendy Marie Ingram, Ph.D. ’15, accepting an award in Japan for her global advocacy in mental health. The UC Berkeley alum and founder of Dragonfly Mental Health has built a movement rooted in both science and lived experience, helping thousands of academics worldwide confront mental illness, prevent loss, and strengthen community care. What began in the wake of tragedy at Berkeley has become a model for institutional compassion: evidence-based training, peer connection, and cultural change that aims to prevent crisis.

Personalized gene editing helped one baby: can it be rolled out widely?

November 3, 2025

Late last year, dozens of researchers spanning thousands of miles banded together in a race to save one baby boy’s life. The result was a world first: a cutting-edge, gene-editing therapy fashioned for a single person, and produced in a record-breaking six months1.

Now, baby KJ Muldoon’s doctors are gearing up to do it all over again, at least five times over. And faster.

The groundbreaking...
