For UC Berkeley Professor Jack Tseng, the world of paleontology never gets old. With each new discovery, paleontologists like him learn more about the animals that walked the earth millions of years ago.

"If you look at books from 50 years ago, they postured dinosaurs very differently from the way we do it today," Tseng says. "This constant profusion of new scientific knowledge into the popular psyche is recorded in children's books, which is a lovely way to see how this science has progressed."

Fossils also hold valuable clues about our planet's future and our role within it as we experience climate change, he says.

"The questions we ask of them have to do with how different species sometimes survive, when others go extinct. Paleontology is sort of pre-adapted to plug in to understanding the future of Earth because we have billions of years of the fossil record to learn from."

This season on Berkeley Voices, we’re exploring the theme of transformation. In eight episodes, we’re exploring how transformation — of ideas, of research, of perspective — shows up in the work that happens every day at UC Berkeley. New episodes will come out on the last Monday of each month, from October through May.

Key takeaways:

• Paleontologists can better understand how dinosaurs and other prehistoric animals looked and lived by studying living animals.
• New discoveries have reshaped what we thought we knew about dinosaurs and the prehistoric world.
• Fossils hold clues about the role of different species of plants and animals during climate change — and the future of Earth.

Like millions of other Americans, UC Berkeley Professor Poulomi Saha watched a lot of docuseries about cults during the COVID-19 pandemic. The more Saha watched, the more they felt a kind of change within themself. "I was absolutely enthralled," said Saha. “My reaction no longer fit that old script, the script that I had internalized. I wasn’t just having a passing interest. I wasn’t sort of mildly terrified. I was thinking, “Oh, wow, that makes good sense.’” Saha wanted to understand why. 

So they started a class, called Cults in Popular Culture, where Saha and their students explore the history of cults, the transformative power of these groups and the conditions that give rise to our collective fascination. After all, Saha says, what better way to make sense of this phenomenon than to ask several hundred Berkeley undergraduates to be test subjects?

This season on Berkeley Voices, we're exploring the theme of transformation. In eight episodes, we’re exploring how transformation — of ideas, of research, of perspective — shows up in the work that happens every day at UC Berkeley. New episodes will come out on the last Monday of each month, from October through May.

Key takeaways:

• Nobody joins a cult; they join a good thing. It’s labeled a cult when it goes bad.
• Our fascination with cults rises amid social and global crises. It happened in 1960s America and it’s happening today. 
• The IRS decides the difference between a religion and a cult. 
• A person who joins a so-called cult undergoes a transformative experience. Instead of calling them "crazy," we should listen.

In a June 2024 study, UC Berkeley psychology professor Keanan Joyner and his colleagues found that by using a combination of methods tailored to the multidimensional nature of psychopathy, we could transform how we identify and understand this personality disorder. "I think that it goes toward having a functional and positive society," Joyner said. "Our collaboration is the substance of what makes humans so wonderful as a species."

Key takeaways:

- Psychopathy exists on a spectrum

- Boldness is a key, yet largely overlooked, trait of psychopathy

- By changing the way we measure psychopathy, we could reduce the harms of the personality disorder

For the first three years of Justin Davidson's childhood in Chicago, his mom spoke only Spanish to him. Although he never spoke the language as a young child, when Davidson began to learn Spanish in middle school, it came very quickly to him, and over the years, he became bilingual.

Now an associate professor in UC Berkeley's Department of Spanish and Portuguese, Davidson is part of a research team that has discovered where in the brain bilinguals process and store language-specific sounds and sound sequences. The research project is ongoing.

This is the final episode of a three-part series with Davidson about language in the U.S. Listen to the first two episodes: "A linguist's quest to legitimize U.S. Spanish" and "A language divided."

There are countless English varieties in the U.S. There's Boston English and California English and Texas English. There's Black English and Chicano English. There's standard academic, or white, English. They're all the same language, but linguistically, they're different.

"Standard academic English is most represented by affluent white males from the Midwest, specifically Ohio in the mid-20th century," says UC Berkeley sociolinguist Justin Davidson. "If you grow up in this country and your English is further away from that variety, then you may encounter instances where the way you speak is judged as less OK, less intelligent, less academically sound."

And this language bias and divide can have devastating consequences, as it did in the trial of George Zimmerman, who killed 17-year-old Trayvon Martin in 2012. 

This is the second episode of a three-part series with Davidson about language in the U.S. Listen to the first and third episode: "A linguist's quest to legitimize U.S. Spanish" and "One brain, two languages."

Spanish speakers in the United States, among linguists and non-linguists, have been denigrated for the way they speak, says UC Berkeley sociolinguist Justin Davidson. It’s part of the country's long history of scrutiny of non-monolingual English speakers, he says, dating back to the early 20th century.

"It’s groups in power — its discourses and collective communities — that sort of socially determine what kinds of words and what kinds of language are acceptable and unacceptable," says Davidson, an associate professor in the Department of Spanish and Portuguese.

But the U.S. is a Spanish-speaking country, he says, and it’s time for us as a nation to embrace U.S. Spanish as a legitimate language variety.

This is the first episode of a three-part series with Davidson about language in the U.S. Listen to other two episodes: "A language divided" and "One brain, two languages."

In his research, UC Berkeley Ph.D. candidate Saagar Asnani looks at music manuscripts from between the 12th and 14th centuries in medieval France. He says only recently have scholars begun to use a wider variety of media and artistic expressions as a way to study language. "If we unpack the genre of music, we will find a very precise record of how language was spoken," Saagar says. 

To read medieval music, Saagar learned five languages — Latin, German, Italian, Catalan and Occitan — making 10 languages that he knows in total (for now, at least). 

In losing the history of pieces of music, Saagar says, we’ve lost languages and cultures that were present and important to the time period. 

And today, at a time when linguistic boundaries are crumbling before our eyes, he says, instead of judging someone who speaks differently from you, realize that “it's actually a way of speaking a language and that we should cherish that because it's beautiful in its own way."

Brandon Sánchez Mejia stood at a giant wall in UC Berkeley’s Worth Ryder Art Gallery and couldn’t believe his eyes. In front of him were 150 black-and-white photos of men’s bodies in all sorts of poses and from all sorts of angles. It was his senior thesis project, "A Masculine Vulnerability," and it was out for the world to see.

"It came from this idea that as men, we are not allowed to show skin as scars or emotions or weakness," said Sánchez, who will graduate from Berkeley this May with a bachelor’s degree in art practice.

Sánchez’s cohort is part of the Department of Art of Practice’s 100th year, a milestone that department chair Ronald Rael said is cause for celebration.

"There have been moments in art practice’s history when it was unclear that art should be at a university at all," said Rael, a professor of architecture and affiliated faculty in art. "And here we are, at 100 years, and it’s one of the most popular majors on campus."

This is a companion podcast to a feature story about Sánchez, published earlier this month on Berkeley News. There, you can view more photos and read about about how Sánchez's mom made him stay inside for a year as a teenager in El Salvador out of fear he'd join a gang. And how, against his mom's wishes and without any money of his own, he decided to pursue an education — no matter what it took.

The self-guided Black history tour at UC Berkeley begins at Memorial Stadium, where student Walter Gordon was a star of the football team more than 100 years ago. It then weaves through campus, making stops at 13 more locations, each highlighting an important person or landmark related to Black history.

There's Ida Louise Jackson Graduate House, named in honor of the first African American woman to teach in Oakland public schools. Next is Barbara Christian Hall, named for the first Black woman to be granted tenure at Berkeley. Other stops include Wheeler Hall and Sproul Plaza, where Black visionaries, like James Baldwin and Martin Luther King Jr., gave famous speeches.

"Just knowing this history, walking around campus and knowing it, you really feel like you belong," said student Daniella Lake, who's on the Black Lives at Cal team that created the tour. "Black people have been here for the past 100 years, and if they were doing all these amazing things then, I can surely do it now."

You can find the self-guided Black history tour at Berkeley on Black Lives at Cal’s website. And soon, on the site, you’ll also be able to sign up for upcoming in-person walking tours.

Bonobos and chimpanzees — the closest extant relatives to humans — could have the longest-lasting nonhuman memory, a study led by a UC Berkeley researcher found. Extensive social memory had previously been documented only in dolphins and up to 20 years.

"What we're showing here," said Berkeley comparative psychologist Laura Simone Lewis, "is that chimps and bonobos may be able to remember that long — or longer."

Berkeley News writer Jason Pohl first published a story about this study in December 2023. We used his interview with Lewis for this podcast episode.
