UC Berkeley scientists uncover neural mechanisms behind long-term memory

July 11, 2025

Every day, our brain takes countless fleeting experiences — from walks on the beach to presentations at work — and transforms them into long-term memories. How exactly this works remains a mystery, but neuroscientists believe that it involves a phenomenon called neural replay, in which neurons rapidly recreate the same activation sequences that occurred during the original experience. Surprisingly, neural replays can happen both before and after an experience, suggesting they help in both memory storage and also future planning.

A T. rex with feathers? Scientists say dinosaurs were likely different from what most of us picture

For a long time, paleontologists thought that the famous, long-extinct apex predator, the Tyrannosaurus rex, may have chased its prey at high speeds. Children’s books and movies often showed the dinosaur sprinting at a terrifying pace; you might remember scenes from the 1993 film Jurassic Park in which a massive T. rex chases...

Are groovy brains more efficient?

June 4, 2025

Many grooves and dimples on the surface of the brain are unique to humans, but they’re often dismissed as an uninteresting consequence of packing an unusually large brain into a too-small skull.

But neuroscientists are finding that these folds are not mere artifacts, like the puffy folds you get when forcing a sleeping bag into a stuff sack. The depths of some of the smallest of these grooves seem to be linked to increased interconnectedness in the brain and better reasoning ability.

Noah Whiteman is a lot of things. He’s a naturalist — he grew up in rural Minnesota, where his dad taught him to hunt with a bow and arrow and make a fire in the rain. He’s an evolutionary biologist at UC Berkeley, the first in his family to go to college. He’s a 2020 Guggenheim Fellow, author...

Infant born with deadly disease now thriving thanks to customized CRISPR treatment six months after birth

May 15, 2025

In a medical first, doctors raced to create a bespoke CRISPR gene therapy for a boy born with a deadly genetic disease and delivered it to him a mere six and a half months after birth.

The CRISPR treatment was administered safely, and the infant is now growing well and thriving, his doctors say. They hope that the treatment will make a liver transplant, which is usually required for survival, unnecessary for him.

The boy inherited two mutated genes that prevented him from breaking down the proteins in his food, which leads to a build-up of ammonia that destroys the liver and...
