You can hear Hari Srinivasan’s confident voice in his academic research papers, his Daily Californiannewspaper articles and in his poetry and essays. But in person, you’re not likely to hear him speak.

That’s because the UC Berkeley psychology major’s ability to vocalize is severely limited due to regressive autism and a neurological disorder known as oral-motor apraxia.

It closed many doors to him. But not at Berkeley, and certainly not now.

Srinivasan is the first nonspeaking person, or as he puts it, “minimally speaking autistic” to win a prestigious...

Over the two decades paleontologist Kevin Padian taught a freshman seminar called The Age of Dinosaurs, one question asked frequently by undergraduates stuck with him: Why are the arms of Tyrannosaurus rex so ridiculously short?

He would usually list a range of paleontologists’ proposed hypotheses — for mating, for holding or stabbing prey, for tipping over a Triceratops — but his students, usually staring a lifesize replica in the face, remained dubious. Padian’s usual answer was, “No one knows.” But he also suspected that scholars who had proposed a solution to...

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 —...
