The powerful gene editing tool CRISPR is already being tested on animal and plant cells. It has even been used on humans. How might this revolutionary tool change our lives? On the one hand, it could cure inherited diseases and rid the world of malaria-spreading mosquitoes. On the other hand, scientists using it are accelerating evolution and introducing novel genetic combinations that could transform our biological landscape in unforeseen ways. We explore the ramifications of this revolutionary technology.Guests:Nathan Rose – Molecular biologist and head of malaria programs at U.K. based biotech company, Oxitec.Hank Greely – Law professor and director of the Center for Law in the Biosciences at Stanford University and author of “CRISPR People: The Science and Ethics of Editing Humans.”Antonio Regalado – Senior Editor for Biomedicine, MIT Technology Review.*Originally aired April 17, 2023Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

A canopy of stars in the night sky is more than breathtaking. Starlight is also an important tool that astronomers use to study our universe. But the growth of artificial light and light pollution are creating dramatic changes to the nighttime environment. Let your eyes adjust to the dark as we travel to a dark sky reserve to gaze upon an increasingly rare view of the Milky Way and explore what we lose when darkness disappears.  Guests:Kim Arcand – Visualization scientist & emerging tech lead, NASA's Chandra X-ray Observatory and author of “Light: The Visible Spectrum and Beyond".Don Jolley – Teacher of Math and Sciences at the Bolinas School in Marin, California who has been leading dark sky tours for three decades.Christopher Kyba – Interdisciplinary Geographic Information Sciences Research Fellow at Ruhr University Bochum.Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

We are closer than ever to finding aliens according to astrophysicist Adam Frank. He isn’t alone in his optimism. Over the last two decades, the tools used to search for extraterrestrials have been advancing mightily. Where we were once only monitoring with radio telescopes, we are now actively looking for bio and technosignatures on exoplanets. Find out why scientists think new technology may be a game changer in the hunt for life off Earth.Guest:Adam Frank – Astrophysicist and author of a new book “The Little Book of Aliens”Featuring music by Dewey Dellay and Jun MiyakeYou can get early access to ad-free versions of every episode by joining us on Patreon.

Electricity plays an important role in our everyday lives, including allowing our bodies to communicate internally. But some research claims electricity may be used to diagnose and treat disease? Could electric pulses one day replace medications?We speak with experts about the growing field of bioelectric medicine and the evidence for electricity’s healing abilities. Their comments may shock you.Guests:Sally Adee – Science journalist, author of “We Are Electric: Inside the 200-Year Hunt for Our Body’s Bioelectric Code, and What the Future Holds"Samantha Payne – Assistant Professor of Biomedical Sciences at University of GuelphKevin Tracey – Neurosurgeon and President of the Feinstein Institute at Northwell Health*Originally aired June 5, 2023Featuring music by Dewey Dellay and Jun MiyakeBig Picture Science is part of the Airwave Media podcast network. Please contact advertising@airwavemedia.com to inquire about advertising on Big Picture Science.You can get early access to ad-free versions of every episode by joining us on Patreon.

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.

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.
