Understanding the gynecological health crisis facing Black women

When Kemi Doll was in medical school, she learned that Black women are twice as likely to die from uterine cancer as white women, and also suffer disproportionately from other uterine-related conditions. What wasn’t explained was why. Now a gynecologic oncologist, Doll has made it her mission to change these trends and improve care for Black women. She joins Flora to discuss her new book, “A Terrible Strength: The Hidden Crisis of the Black Womb and Your Survival Guide to Healing.” They explore the way systemic racism and the normalization of Black women’s pain lead to later diagnoses of uterine cancer and poorer health outcomes for a range of gynecologic conditions including fibroids, endometriosis, and heavy periods. And Doll explains the problem with using reproductive health as a synonym for uterine health. Guest: Dr. Kemi Doll is a gynecologic oncologist and professor at the University of Washington Schools of Medicine and Public Health. Other episodes you may enjoy: Endometriosis Is Common.

Data about your body is up for sale. Who's buying it?

Cameras and sensors are just about everywhere, recording your face, how you walk, where you go, your heart rate. And AI is making it easy to amass and analyze that data about all of us. Privacy attorney Anne Toomey McKenna joins Host Flora Lichtman to talk about the ubiquity of biometric surveillance and how data brokers are gathering and selling our information, including to law enforcement. Guest: Anne Toomey McKenna is an attorney specializing in privacy and biometric surveillance. She’s on the Advisory Board for AI Policy at the Institute for Electrical and Electronics Engineers - USA. Other episodes you may enjoy: Why Worry About My Data If I Have Nothing To Hide?

Sci-fi thriller combines aliens, robots, and Cherokee culture

Breaking news out of eastern Oklahoma! A hole in the sky has opened. Through it, an unidentified turtle-shaped craft has descended. Alerts say that this is first contact. So it goes in the sci-fi thriller “Hole in the Sky.” In the book, author Daniel H. Wilson imagines this moment where we meet alien life for the first time. It’s set in the heart of Cherokee Nation and follows characters including a military man, a NASA scientist, and a Cherokee father named Jim who is just trying to survive the alien entity. Wilson joins Flora for a conversation about the book and how he integrated elements of Cherokee culture with science fiction. They get into the ways we project our own fears—like genocide and slavery—onto aliens, and how science fiction helps us imagine the unimaginable. The SciFri Book Club is reading “Hole in the Sky” during May and June. Join us to read along! Read an excerpt from “Hole in the Sky.” Guest: Dr. Daniel H. Wilson is a Cherokee citizen and bestselling author of “Robopocalypse,” “Hole in the Sky,” and several other books. He holds advanced degrees in machine learning and robotics and lives in Portland, Oregon. Transcripts for each episode are available within 1-3 days at sciencefriday.com. Want SciFri gear?

Beavers could be humans' biggest ally, if we let them

Beavers are having a moment, thanks to the new Pixar movie “Hoppers.” Amid some body-swapping shenanigans, the film is about humans coexisting with wildlife—particularly oversized rodents capable of reworking landscapes in profound ways. The beaver science consultant on “Hoppers,” Emily Fairfax, joins Flora to talk about beavers’ brilliant, chaotic landscape engineering, and how the creatures show up in the movie. Then, reporter Zac Ziegler walks Flora through a successful beaver-centric engineering project in Oregon. Guests: Emily Fairfax is an assistant professor of geography at the University of Minnesota. She was a science consultant for the Pixar movie “Hoppers.” Zac Ziegler is a reporter at KLCC in Eugene, Oregon.

Searching for dark matter, deep in the Earth

Deep in an active nickel mine near Sudbury, Ontario, researchers are installing and calibrating a set of sensitive detectors. They hope that the location roughly 6,800 feet underground will screen out much of the ordinary radiation and cosmic rays felt on the surface, and allow their detectors to sense tiny disturbances caused by a dark matter particle passing close to the nucleus of one of the germanium atoms in a target material. If successful, the SuperCDMS SNOLAB experiment may shed some light on the nature of dark matter, an unseen something that is thought to make up around 85% of the matter in the universe. Priscilla Cushman, a physicist who has been working on the project for over 20 years, joins Host Flora Lichtman to describe the hunt, the timeline of the experiment, and the big unknowns facing the SuperCDMS team. Guest: Dr. Priscilla Cushman is spokesperson for the SuperCDMS SNOLAB experiment, and a professor in the School of Physics and Astronomy at the University of Minnesota.

The decades-long movement to kill FEMA

Hurricane season officially begins in June. And in the event of a big storm, local and state governments often rely on help from the Federal Emergency Management Agency or FEMA. But, President Trump has questioned the value of the agency. “I've never been a big fan of FEMA. I like to keep it local. I like to see governors and neighboring states help each other as opposed to FEMA,” Trump said in March. We’ve heard this from the administration about other federal agencies, but FEMA is a special case. People have mistrusted this agency since its founding in the late 1970s. Host Flora Lichtman talks with Micah Loewinger, co-host of the show “On The Media,” who traced FEMA’s history in a new series called “American Emergency: The Movement to Kill FEMA.” Guest: Micah Loewinger is co-host of On The Media.Other episodes you may enjoy: As Disasters Escalate, What’s The Future Of FEMA?

What cats and dogs hear + A 'smell map' of the nose

Animal neuroaudiologist Pete Scheifele joins us to answer some burning questions from SciFri listener Paul: Why can dogs and cats hear a wider range of frequencies than we do? Is it in their ears, their brains? And what would life be like if you had dog ears or cat ears? And, scientists have created the first “smell map” of the nose using a mouse model. Host Flora Lichtman talks with neurobiologist Bob Datta about this latest research, and what it tells us about olfaction. Guests: Dr. Pete Scheifele is a neuroaudiologist at the University of Cincinnati and executive director of the FETCHLAB, an animal audiology clinic and lab. Dr. Bob Datta is a neurobiologist at Harvard Medical School. Other episodes you may enjoy: What’s That Smell?

How do you study microplastics in a plastic-filled lab?

The news we hear about plastic is often alarming: We have a spoon’s worth of plastics in our brains, and there are microplastics in our hearts, lymph nodes, and bloodstreams. Plastics are ubiquitous, but the reality might be more complicated than it seems. It turns out that measuring microplastics is really, really difficult. One reason? Because we’re surrounded by plastics! Think of the pipettes and petri dishes and gloves we use in labs. Host Flora Lichtman chats with microplastics researcher Cassandra Rauert about the difficulties of studying plastics in the human body and what she’s doing about it—like how she designed a whole lab made almost entirely of stainless steel and glass. Guest: Dr. Cassandra Rauert is a senior research fellow studying microplastics exposure at the University of Queensland in Australia.

Keeps me informed

This show regularly provides information I can use in my life and keeps me informed on matters that I may need to consider when I vote in the future.
Bias and one sided

Mzee G

I listen to this show on a regular basis. And I enjoy the content part of the time. However, they have people come on with a political bias and express their personal views as if it’s fact.
Smart, curious and always worth a listen

I love this show! Ira and Flora are both fantastic, different styles but equally curious and fun. I learn something new every time, even on topics I don’t expect to enjoy. It’s a great mix of important science and a much-needed escape from our current hellscape.
