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...

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...

"Diversity in STEM enhances discovery and provides a catalyst for social change by enabling an equity of experience. Our ultimate goal is to diversify the next generation of STEM leaders and empower them to achieve their academic and professional aspirations. We aim to change the face of science and technology."

The University of California, Berkeley is excited to announce the launch of the Life Sciences Entrepreneurship Center (LSEC). The Center was established to foster the creation of innovative and transformative life sciences companies for the betterment of society and the Berkeley campus life sciences community. LSEC is designed to complement and catalyze the many existing resources of Berkeley’s innovation and entrepreneurship ecosystem, not compete with them.
