UC Berkeley's Division of Biological Sciences launches new health and wellness minor

October 21, 2021

Woman biking on campusUC Berkeley has announced the addition of a new health and wellness minor in the College of Letters & Science. This interdisciplinary minor centers on a three-course core, covering the cultural, psychological, and physiological aspects of health and wellness. There are also two upper-division electives, curated from a diverse list of...

"Basic Science Lights the Way" Returns & A New Video from Biological Sciences Division

October 18, 2021

Basic Science 2021 cover image“There’s this funny, almost magical aspect of following curiosity-based research, when you just try to understand how the world works,” said professor of physics, Saul Perlmutter, reflecting on the ingenuity that is intrinsic to basic research. “Somehow, that’s made it possible for us to leapfrog all sorts of problems.”

Neuroscientists roll out first comprehensive atlas of brain cells

October 6, 2021

Brain slice from a transgenic mouseWhen you clicked to read this story, a band of cells across the top of your brain sent signals down your spine and out to your hand to tell the muscles in your index finger to press down with just the right amount of pressure to activate your mouse or track pad.

A slew of new studies now shows that the area of the brain responsible for initiating this action — the primary...

America’s Top Colleges 2021: For The First Time A Public School Is Number One

September 8, 2021

Public universities can deliver the most outstanding education to the broadest range of students at the most affordable price. That’s the message of Forbes’ 2021 ranking of top colleges.

For the first time ever on a national ranking of America’s best colleges, a public school, the University of California at Berkeley, is in the No. 1 spot (In 2009 West Point topped our list, but military academies are slightly different animals). Of the top 25 schools in the Forbes ranking, six are public, including three other U.C.s, the University of Michigan and the University of Florida.

Rats prefer to help their own kind. Humans may be similarly wired

July 13, 2021

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new UC Berkeley research pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share the same neural bias.

The findings, published today, Tuesday, July 13, in the journal eLife, suggest that altruism, whether in rodents or humans, is motivated by social bonding and familiarity rather than sympathy or guilt.

“We have found that the group identity of the distressed...

Here’s why poisonous animals don’t poison themselves

August 5, 2021

How do poisonous animals like the hooded pitohui, a small, drab bird whose orange and black feathers are laced with poison, keep from poisoning themselves? For decades, the best theory has been that the birds and frogs evolved specially adapted sodium channels. But a study in the Journal of General Physiology overturns that notion. The researchers provide evidence that pitohui and poison frogs have what they call "toxin sponges," or proteins that mop up the fatal toxins before they cause damage. Rebecca Tarvin, an evolutionary biologist at University of California, Berkeley...

Squirrels Use Gymnastics to Navigate Treetop Canopies

August 5, 2021

In treetops all around the world, squirrels leap meters through the air to get from branch to branch. In this natural arena the squirrels scurry around to find morsels of food, all the while trying to evade occasional airborne predators such as hawks. But the speed and ease with which they navigate the challenging and unpredictable canopy environment is “spectacular,” says University of California, Berkeley, biomechanics researcher Robert Full. The animals easily land leaps several times the length of their body. And we do not really know how they do it, Full says. “How do they know...
