Is your windshield accumulating less bug splatter? Insects, the most numerous animals on Earth, are becoming scarcer, and that’s not good news. They’re essential, and not just for their service as pollinators. We ask what’s causing the decrease in insect populations, and how can it be reversed. Also, the story of how California’s early citrus crops came under attack – a problem that was solved by turning Nature on itself. And how chimpanzee “doctors” use insects to treat wounds.We investigate the small and the many on “The Latest Buzz.”Guests:Martin Kernan – Historian and journalist. His article, “The Bug That Saved California,” appeared in the January-February 2022 issue of the SmithsonianAlessandra Mascaro – Evolutionary Biologist, currently working at the Ozouga Chimpanzee Project, co-author of the Current Biology paper, “Application of insects to wounds of self and others by chimpanzees in the wild”Lara Southern – Doctoral student at the University of Osnabruck, co-author of the Current Biology paper, “Application of insects to wounds of self and others by chimpanzees in the wild”Oliver Milman – Environment correspondent for The Guardian in the U.S. and author of “The Insect Crisis: The Fall of the Tiny Empires that Run the World”Featuring music by Dewey Dellay and Jun Miyake*Originally aired March 28, 2022Big 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.

The 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. Featuring music by Dewey Dellay and Jun MiyakeWe've been nominated for a Webby!

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 riskFeaturing music by Dewey Dellay and Jun MiyakeWe've been nominated for a Webby!

Are we alone in the universe? Is there other intelligence out there? COSMIC, the most ambitious SETI search yet, hopes to answer that. We hear updates on this novel signal detection project being conducted on the Very Large Array in the desert of New Mexico. Also, we chat with award-winning science fiction writer Ted Chiang about how he envisions making contact with aliens in his stories, including the one that was the basis for the movie Arrival. And find out why some scientists don’t want only to listen for signals, they want to deliberately transmit messages to aliens. Is that wise and, if we did it, what would we say? Guests:Chenoa Tremblay – Postdoc researcher in radio astronomy for the SETI Institute and member of COSMIC science teamTed Chiang – Nebula and Hugo award-winning science fiction writer, best known for his collections, Stories of Your Life and Others and ExhalationDouglas Vakoch – Founder and president of METI International, a nonprofit research and educational organization devoted to transmitting intentional signals to extraterrestrial civilizationsFeaturing 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.

Scientists are increasingly finding their expertise questioned by non-experts who claim they’ve done their own “research.” Whether advocating Ivermectin to treat Covid, insisting that climate change is a hoax, or asserting that the Earth is flat, doubters are now dismissed by being told to “do your own research!” But is a Wiki page evidence? What about a YouTube video? What happens to our quest for truth along the way? Plus, a science historian goes to a Flat Earth convention to talk reason.Guests: Yvette Johnson-Walker – epidemiologist at the University of Illinois College of Veterinary Medicine, and affiliate faculty with the University of Illinois Chicago School of Public Health.

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 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.

Global junk entrepreneurs are leading the way in turning trash to treasure, while right-to-repair advocates fight for legislation that would give you a decent shot at fixing your own electronic devices. And, if you toss food scraps down the drain as you cook, are you contributing to a “fatberg” horror in the sewer?Guests: John Love – Synthetic biologist at the University of Exeter Adam Minter – Author of Secondhand: Travels in the New Global Garage Sale Amanda Preske – Chemist and the owner of Circuit Breaker Labs Nathan Proctor – National campaign director for U.S. Public Interest Research Group – (PIRGS) Right to Repair campaign Kyle Wiens – CEO of I-Fixit, an Internet repair community Originally aired December 16, 2019Big Picture Science is part of the Airwave Media podcast network. Please contact sales@advertisecast.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.
