Before everything could come up roses, there had to be a primordial flower – the mother, and father, of all flowers. Now scientists are on the hunt for it. The eFlower project aims to explain the sudden appearance of flowering plants in the fossil record, what Darwin called an “abominable mystery.”Meanwhile, ancient flowers encased in amber or preserved in tar are providing clues about how ecosystems might respond to changing climates. And, although it was honed by evolution for billions of years, can we make photosynthesis more efficient and help forestall a global food crisis?Guests:Eva-Maria Sadowski - Post doctoral paleobotanist at the Museum für Naturkunde, BerlinRegan Dunn - Paleobotanist and assistant Curator at the La Brea Tar Pits and MuseumRoyal Krieger - Rosarian and volunteer at the Morcom Rose Garden, Oakland, CaliforniaRuby Stephens - Plant ecology PhD candidate at Macquarie University in Australia, and member of the eFlower ProjectStephen Long - Professor of Plant Science, University of IllinoisFeaturing music by Dewey Dellay and Jun Miyake*Originally aired March 13, 2023You can get early access to ad-free versions of every episode by joining us on Patreon.

They’re cute and cuddly. But they can also be obnoxious.Science writer Mary Roach has numerous tales about how our animal friends don’t always bow to their human overlords and behave the way we’d want. The resulting encounters, such as when gulls disrupt the Vatican’s Easter mass, make for amusing stories. But others, such as wolves threatening farmers’ livestock, can be tragic.We hear what happens at the messy crossroads of human and wildlife encounters.Guest:Mary Roach – Author of bestselling nonfiction books, most recently “Fuzz: When Nature Breaks the Law.”*Originally aired September 13, 2021Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

Max Fisher from The New York Times discusses the evolutionary reasons humans can't thrive on social media. Douglas Rushkoff explores tech billionaires' extreme preparations. Alex Mesoudi talks about the impact of social media on human cognition. The podcast explores the cultural evolution and potential changes in the social media landscape.

It’s not just facts that inform our decisions. They’re also guided by how those facts feel. From deciding whether to buckle our seat belts to addressing climate change, how we regard risk is subjective. In this extended conversation with an expert on the psychology of risk, find out about our exaggerated fears, as well as risks we don’t take seriously enough. Meanwhile, while experts warn society about the dangers of self-aware AI – are those warnings being heeded?Guest: David Ropeik – Professor emeritus Harvard University, and expert on the psychology of risk*Originally aired April 10, 2023Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

Ever heard of a beauty quark? How about a glueball? Physics is full of weird particles that leave many of us scratching our heads. But these tiny particles make up everything in the quantum world and in us and are the basis of the fundamental scientific theory called The Standard Model. But it doesn’t explain everything. It can’t account for dark matter or dark energy, for example. We find out whether new physics experiments might force us to rewrite the Standard Model. Plus, we discuss a NASA proposal to fly spacecraft close to the sun in search of new physics.Guests:Phil Plait – Aka the Bad Astronomer, former astronomer on Hubble, teacher, lecturer and debunker of conspiracy theories. He is also the author of a new book “Under Alien Skies: A Sightseer’s Guide to the Universe.”Harry Cliff – Particle physicist at the University of Cambridge who works on the LHCb experiment at the largest particle physics laboratory in the world, CERN.

Has children’s play become too safe? Research suggests that efforts to prioritize safety harms children’s mental and physical development during play and contribute to anxiety. One solution: introduce risk into play. We visit an adventure playground where kids play unsupervised with anything from scraps of metal to hammers and nails. Plus, what are the evolutionary benefits of play? After all, we’re not the only species who like to roughhouse, sled, or chase balls. And, reclaiming play for those who have outgrown recess.Guests:David Toomey - Professor of English, University of Massachusetts. Amherst and author of “Kingdom of Play: What Ball-Bouncing Octopuses, Belly-Flopping Monkeys, and Mud-Sliding Elephants Reveal About Life Itself.”Mariana Brussoni - Developmental psychologist who studies children's outdoor risky play, and professor at the University of British Columbia in the Faculty of MedicineYoni Kallai - Interim director, head playworker and co-founder of play:groundNYCPeter Gray - Psychology researcher at Boston College and author of "Free to Learn: Why Unleashing the Instinct to Play Will Make Our Children Happier, More Self-Reliant, and Better Students for Life"Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

How frequently do you think about fasteners like screws and bolts? Probably not very often. But some of them a storied history, dating back to Egypt in the 3rd century BC. They aren’t just ancient history. They help hold up our bridges and homes today. Join us as we dissect a handful of engineering inventions that keep our world spinning and intact.Guests:Roma Agrawal - structural engineer and author of "Nuts and Bolts: Seven Small Inventions That Changed the World (in a Big Way)"Ron Gordon - watchmaker, New York CityFeaturing music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

It was a radical idea a century ago, when Einstein said space and time can be bent, and gravity was really geometry. We hear how his theories inspire young minds even today.At small scales, different rules apply: quantum mechanics and the Standard Model for particles. New experiments suggest that muons – cousins of the electron – may be telling us that the Standard Model is wrong. Also, where the physics of both the large and small apply, and why black holes have no hair.Guests:Hakeem Oluseyi – Astrophysicist, affiliated professor at George Mason University, and author of “A Quantum Life: My Unlikely Journey from the Street to the Stars”Janna Levin – Professor of physics and astronomy, Barnard College at Columbia UniversityMark Lancaster – Professor of particle physics, University of Manchester*Originally aired August 16, 2021Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

Above the Arctic Circle, much of the land is underlaid by permafrost. But climate change is causing it to thaw. This is not good news for the planet. As the carbon rich ground warms, microbes start to feast… releasing greenhouse gases that will warm the Earth even more.Another possible downside was envisioned by a science-fiction author. Could ancient pathogens–released from the permafrost’s icy grip–cause new pandemics? We investigate what happens when the far north defrosts.Guests:Jacquelyn Gill – Associate professor of paleoecology at the University of Maine.Jim Shepard – Novelist and short story writer, and teacher of English at Williams College, and author of “Phase Six.”Scott Saleska – Global change ecologist, professor of Ecology and Evolutionary Biology at the University of Arizona, and co-founder of IsoGenie.Originally aired September 6, 2021Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

Birds have it going on. Many of these winged dinosaurs delight us with their song and brilliant plumage. Migratory birds travel thousands of miles in a display of endurance that would make an Olympic athlete gasp.We inquire about these daunting migrations and how birds can fly for days without rest. And what can we do to save disappearing species? Will digital tracking technology help? Plus, how 19th century bird-lovers, appalled by feathered hats, started the modern conservation movement.Guests:Scott Weidensaul – Ornithologist and naturalist and author of “A World on the Wing: the Global Odyssey of Migratory Birds.”Kassandra Ford – Doctoral candidate in evolutionary biology at the University of Louisiana at Lafayette.Michelle Nijhuis – Science journalist and author of “Beloved Beasts: Fighting for Life in an Age of Extinction.”Originally aired May 10, 2021Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.
