In this Berkeley Voices episode, Bree Rosenblum, a professor of global change biology at UC Berkeley, talks about why we need to stop blaming each other for the environmental crisis that we’re in, and instead confront its root causes and expand our ideas of what it means to be human on our planet. “I really think that if we’re not addressing culture at a really deep level, that we cannot address climate change,” said Rosenblum. “Do we want humanity to mean what it has meant in the past, or do we want to create a new meaning for our species and for our purpose?”

Researchers at the University of California, Berkeley, have found that a drug once widely used to wean alcoholics off of drinking helps to improve sight in mice with retinal degeneration.

The drug may revive sight in humans with the inherited disease retinitis pigmentosa (RP), and perhaps in other vision disorders, including age-related macular degeneration.

A group of scientists led by Richard Kramer, UC Berkeley professor of molecular and cell biology, had previously shown that a chemical —...

Mentoring and support program activates students’ potential for success in biology, at Berkeley, and in life. This video illustrates the history and impact of the Biology Scholars program — and the importance of the community and legacy it creates.

A recent study links anxiety behavior in rats, as well as post traumatic stress disorder (PTSD) in military veterans, to increased myelin — a substance that expedites communication between neurons — in areas of the brain associated with emotions and memory.

The results, reported by scientists at the University of California, Berkeley, and UC San Francisco (UCSF), provide a possible explanation for why some people are resilient and others vulnerable to traumatic stress, and for the varied symptoms — avoidance behavior, anxiety and fear, for example — triggered by the memory of such...
