The Edge

Octopuses and humans have very little in common. It’s not just a matter of their eight limbs and cool camouflage—we haven’t had a shared ancestor for more than half a billion years, before dinosaurs walked the earth. But there’s one surprising thing we do seem to share: MDMA makes us both a lot cuddlier. For neuroscientist Gül Dölen, this was a huge insight into the powerful role psychoactive drugs can play in animal social behavior. Now a pioneer in the burgeoning field of psychedelic research at UC Berkeley, Dölen discusses her quest to understand how these drugs could be harnessed as tools in learning and therapeutics.

Don’t let the term “climate change” mislead you. It’s true that our environment is changing in all sorts of ways as we continue to pollute and exploit and manipulate our planet. But even as we brace for more historic typhoons and biblical floods, there's an invisible and pervasive force that is wreaking havoc on us all: heat. In this episode, we speak with environmental journalist and Berkeley alumnus Jeff Goodell about his latest book, The Heat Will Kill You First, the potentially lethal effects that rising temperatures will have on our lives and on our planet, and what we can do to prepare for it.

Nearly four years have passed since COVID swept the globe, infecting millions and bringing society to a grinding halt. The ensuing months saw strict mask mandates, revolutionary vaccines, new viral strains, and—finally—a return to some sort of normal. With the end of the public health emergency and a sudden disappearance of the once-ubiquitous masks, it’s easy to feel like the pandemic is, well, over. But some would strongly disagree with that prognosis—and one group in particular: people suffering from the lasting effects of long COVID. In this episode, we talk with Dr. Kim Rhoads, a Berkeley grad and associate professor at UCSF, about the challenge of diagnosing this post-viral illness, its wide-ranging and often mysterious symptoms, and why you might not want to throw out your mask just yet.

Roughly every second, a star explodes. Beyond treating astronomers to a radiant light display, these dramatic supernova events contain vast amounts of information about the origin, behavior, and ultimate demise of our universe. UC Berkeley astrophysicist Sarafina El-Badry Nance, has dedicated her life to studying really big exploding stars and what they tell us about our ever-expanding universe. She joins us this episode to talk about her own path to star-gazing and the big, existential questions that keep her eyes to the sky.

We’re back with something a little different this month. In the wake of this year’s historic floods, wildfires, and hurricanes, we asked ourselves: What would it look like to take a more optimistic attitude towards slowing climate change? In that spirit, we’re sharing an episode of The Science of Happiness, a podcast co-produced by UC Berkeley's Greater Good Science Center and PRX. The first in a miniseries the center is airing called “Climate, Hope and Science,” this episode features an interview with author Rebecca Solnit in which she explores how embracing uncertainty enables people to move beyond climate anxiety and despair to hope and action.

For centuries, doctors have medically treated people differently according to their race because they believed that race was biological. But in recent years, medical professionals and activists have argued that this is both wrongheaded and can be dangerous to people’s health. In this episode, we talk to UC Berkeley grad Stephen Richmond, a primary care physician and assistant professor at Stanford, about the movement to abolish biological race from medicine and how race and biology do and do not intersect.

Car-free streets are no longer just an urban fantasy. In cities across the nation, a movement is growing to return the streets to the people. In this episode, we talk to two advocates from UC Berkeley about their quest to ‘pedestrianize’ Telegraph Avenue and their grand vision for a more walkable, bikeable future.

The teens are not alright! In fact, they’re experiencing a sleep crisis. In this episode, we talk to journalist and UC Berkeley grad Lisa Lewis about why teens have different sleep needs than the rest of us and how she worked to get more sleep for all Californian teens. We explore sleep hygiene and what it means to restructure society around a vital health need.

Today, we’re featuring the audio version of California magazine’s recent cover story, “Into the Ishi Wilderness.” In 1911, a Yahi Native American man walked out of the wilderness near Oroville, California. The famed anthropologist Alfred Kroeber brought him to UC Berkeley’s campus. What happened next is still being hotly debated almost 100 years later.
