Talking tongues, detecting beer, and shifting perspectives on females May 25, 2023

Show notes

Why it’s so hard to understand the tongue, a book on a revolutionary shift toward studying the female of the species, and using proteomics to find beer in a painting

First on the show this week, Staff Writer Elizabeth Pennisi joins host Sarah Crespi to talk tongues: Who has them, who doesn’t, and all their amazing elaborations.

We also have the first in a new six-part series on books exploring the science of sex and gender. For this month’s installment, host Angela Saini talks with evolutionary biologist Malin Ah-King about her book The Female Turn: How Evolutionary Science Shifted Perceptions About Females.

Finally, detecting beer in early 19th century Danish paintings. Heritage scientist Fabiana Di Gianvincenzo of the Heritage Science Laboratory at the University of Ljubljana talks about her Science Advances paper on using proteomics to dig out clues to artistic practices of the day and how they fit in with the local beer-loving culture.

The earliest evidence for kissing, and engineering crops to clone themselves May 18, 2023

Show notes

Cloning vigorous crops, and finding the first romantic kiss

First up this week, building resilience into crops. Staff Writer Erik Stokstad joins host Sarah Crespi to discuss all the tricks farmers use now to make resilient hybrid crops of rice or wheat and how genetically engineering hybrid crop plants to clone themselves may be the next step.

After that we ask: When did we start kissing? Troels Pank Arbøll is an assistant professor of Assyriology in the department of cross-cultural and regional studies at the University of Copenhagen. He and Sarah chat about the earliest evidence for kissing—romantic style—and why it is unlikely that such kisses had a single place or time of origin.

The value of new voices in science and journalism, and what makes something memorable Apr 27, 2023

Show notes

Science’s editor-in-chief and an award-winning broadcast journalist discuss the struggles shared by journalism and science, and we learn about what makes something stand out in our memories

First up on the show this week: Science Editor-in-Chief Holden Thorp talks with Amna Nawaz, an award-winning broadcast journalist and host of the PBS NewsHour, about the value of new voices in science and journalism and other things the two fields have in common.

Are there features of things that make them memorable, regardless of meaning? Wilma Bainbridge, an assistant professor in the department of psychology at the University of Chicago, joins host Sarah Crespi to discuss her Science Advances paper on teasing apart the features of memorability.

Mapping uncharted undersea volcanoes, and elephant seals dive deep to sleep Apr 20, 2023

Show notes

What does it mean that we have so many more seamounts than previously thought, and finding REM sleep in seals

First up on the show this week: so many seamounts. Staff News Writer Paul Voosen joins host Sarah Crespi to discuss a study that mapped about 17,000 never-before-seen underwater volcanoes. They talk about how these new submarine landforms will influence conservation efforts and our understanding of ocean circulation.

Next up, how do mammals that spend 90% of their time in the water, get any sleep? Jessica Kendall-Bar, the Schmidt AI in Science postdoctoral fellow at the Scripps Institution of Oceanography at the University of California, San Diego, is here to talk about her work exploring the sleep of elephant seals by capturing their brain waves as they dive deep to slumber.

Finally, in a sponsored segment from Science/AAAS Custom Publishing Office, Jackie Oberst, assistant editor for the Custom Publishing office, interviews Friedman Brain Institute Director Eric Nestler and Director of Drug Discovery Paul Kenny, two experts on addiction from the Icahn School of Medicine at Mount Sinai. This segment is sponsored by the Icahn School of Medicine at Mount Sinai.

More precise radiocarbon dating, secrets of hibernating bear blood, and a new book series Apr 13, 2023

Show notes

Anchoring radiocarbon dates to cosmic events, why hibernating bears don't get blood clots, and kicking off a book series on sex, gender, and science

First up this week, upping the precision of radiocarbon dating by linking cosmic rays to isotopes in wood. Producer Meagan Cantwell talks with Online News Editor Michael Price about how spikes in cosmic rays—called Miyake events—are helping archaeologists peg the age of wooden artifacts to a year rather than a decade or century.

Next on the show, we have a segment on why bears can safely sleep during hibernation without worrying about getting clots in their blood. Unlike bears, when people spend too much time immobilized, such as sitting for a long time on a flight, we risk getting deep vein thrombosis—or a blood clot. Johannes Müller-Reif of the Max Planck Institute of Biochemistry talks with host Sarah Crespi about what we can learn from bears about how and why our bodies decide to make these clots and what we can do to prevent them.

Stay tuned for an introduction to our new six-part series on books exploring science, sex, and gender. Guest host Angela Saini talks with scholar Anne Fausto-Sterling about the books in this year's lineup and how they were selected.

We’ve been nominated for a Webby! Please support the show and vote for us by 20 April.

Why not vaccinate chickens against avian flu, and new form of reproduction found in yellow crazy ants Apr 06, 2023

Show notes

Why some countries, such as China, vaccinate flocks against bird flu but others don’t, and male ants that are always chimeras

First up this week, highly pathogenic avian influenza is spreading to domestic flocks around the globe from migrating birds. Why don’t many countries vaccinate their bird herds when finding one case can mean massive culls? Staff News Writer Jon Cohen joins host Sarah Crespi to discuss the push and pull of economics, politics, and science at play in vaccinating poultry against bird flu.

Next up, a crazy method of reproduction in the yellow crazy ants (Anoplolepis gracilipes). Hugo Darras, an assistant professor in the Institute of Organismic and Molecular Evolution at Johannes Gutenberg University, talks about how males of this species are always chimeras—which means their body is composed of two different cell lines, one from each parent.

How the Maya thought about the ancient ruins in their midst, and the science of Braille Mar 30, 2023

Show notes

On this week’s show: How people in the past thought about their own past, and a detailed look at how Braille is read

First up this week, what did people 1000 years ago think about 5000-year-old Stonehenge? Or about a disused Maya temple smack dab in the middle of the neighborhood? Contributing Correspondent Lizzie Wade joins host Sarah Crespi to discuss how Mesoamerican sites are revealing new ways that ruins were incorporated into past peoples’ lives.

Next up on this week’s show is a segment from the AAAS meeting on reading science and Braille. We hear from Robert Englebretson, an associate professor of linguistics at Rice University, about filling in a gap in reading science research when it comes to how Braille is read, written, and learned.

New worries about Earth’s asteroid risk, and harnessing plants’ chemical factories Mar 23, 2023

Show notes

On this week’s show: Earth’s youngest impact craters could be vastly underestimated in size, and remaking a plant’s process for a creating a complex compound

First up this week, have we been measuring asteroid impact craters wrong? Staff Writer Paul Voosen talks with host Sarah Crespi about new approaches to measuring the diameter of impact craters. They discuss the new measurements which, if confirmed, might require us to rethink just how often Earth gets hit with large asteroids. Paul also shares more news from the recent Lunar and Planetary Science Conference in Texas.

Next up, pulling together all the enzymes used by a plant to make a vaccine adjuvant—a compound used to boost the efficacy of vaccines—in the lab. Anne Osbourn, a group leader and professor of biology at the John Innes Centre in Norwich, England, talks about why plants are so much better at making complex molecules, and an approach that allows scientists to copy their methods.
