Big Picture Science for April 26 - Skeptic Check: Flat Earth

Big Picture Science - Skeptic Check: Flat Earth

(Repeat) The Earth is not round. Technically, it’s an oblate spheroid. But for some people, the first statement is not even approximately correct. Flat Earthers believe that our planet resembles – not a slightly squashed grapefruit – but a thick pancake. A journalist who covered a Flat Earth convention describes the rationale behind this ever-more popular belief.

So how do you establish science truth? We look at the difference between a truly scientific examination of extraordinary claims and approaches that feel and look science-y but aren’t.

Find out how one man will use telescopes and balloons in the desert to demonstrate that the Earth is a globe, while a biologist runs a test on the waters of Loch Ness to see if it contains prehistoric reptile DNA.

And what happens when amateur investigators chase ghosts, UFOs, and Bigfoot with science instruments, but without an understanding of the scientific method.

Guests:

• James Underdown – Executive Director of the Center for Inquiry in Los Angeles and of the Independent Investigations Group. The results of his experiment are available here.
• Alex Moshakis – Journalist who writes for the Observer, the Guardian, and Esquire. His article on the U.K.’s first Flat Earth convention appeared in May, 2018 in the Guardian.
• Harry Dyer – Lecturer in education at the University of East Anglia. His article about the flat earth convention is titled "I Watched an Entire Flat Earth Convention for my Research, Here is What I Learned."
• Neil Gemmell – Professor in the Department of Anatomy, University of Otago, New Zealand
• Sharon Hill – Geologist, science writer, speaker, and author of "Scientifical Americans: The Culture of Amateur Paranormal Researchers."

Big Picture Science for April 19 - Waste Not

Big Picture Science - Waste Not

Why create more landfill? Perhaps you should resist the urge to toss those old sneakers, the broken ceiling fan, or last year’s smart phone. Instead, repurpose them! 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

Big Picture Science for April 12 - Venom Diagram

 

 

 

 

 

Big Picture Science - Venom Diagram

(REPEAT) We all get defensive sometimes. For some animals, evolution has provided a highly effective mechanism for saying “back off!”. A puncture by a pair of venom-filled fangs gets the point across nicely.

But one animal’s poison may be another’s cure. Some dangerous critters churn out compounds that can be synthesized into life-saving drugs.

Meet the spiny, fanged, and oozing creatures who could help defend us against such illnesses as hypertension and kidney disease.

Plus, the King of Pain - a scientist who has been stung by more than 80 species of insects in his pursuit of a better understanding of venom’s biochemistry. Find out which winged stinger scored the highest on his pain index.

And, why the drug we need most may come from the quietest members of the biosphere: turning to plants for a new generation of antibiotics.

Guests:

• Owen Maercks – Co-owner, East Bay Vivarium, Berkeley, California 
• Justin Schmidt – Entomologist, University of Arizona, author of “The Sting of the Wild: The Story of the Man Who Got Stung for Science”

Big Picture Science for April 05 - Volcanic Mind Melt

Big Picture Science - Volcanic Mind Melt

The Earth’s surface is dappled with more than a thousand volcanoes. They mark the edges of tectonic plates, spewing hot gas and ash, and boiling over with lava. We can detect the warning signs of an eruption, but why is it still so hard to predict?

Meet a few currently active hot heads: Mauna Loa, Nyiragongo, Fagradalsfjall, and Soufrière – and find out what gives them individual personalities. Plus, what a newly excavated snack bar in Pompeii, buried and preserved when Vesuvius erupted in 79 AD, can teach us about eruptions.

Big Picture Science for Mar 29 - Skeptic Check: Useful Delusions

Big Picture Science - Skeptic Check: Useful Delusions

Can self-deception be useful? During the pandemic, it has been fashionable to say that we’re “following the science,” and that our behavior is determined by verifiable facts. We are, after all, self-declared rational beings, and that’s clearly useful in guiding our reaction to a pandemic. It’s true that fear and suspicion have caused some to make contrary choices such as declining vaccines, but that behavior is considered irrational. But are there situations when delusional thinking can help you thrive? Why are we not as rational as we think?

Guests:

• Steven Novella – Neurologist and professor at Yale University School of Medicine. Host of the Skeptics Guide to the Universe podcast.
• Shankar Vedantam – Host of the Hidden Brain podcast and radio show, and co-author of “Useful Delusions: The Power & Paradox of the Self-Deceiving Brain.”

Big Picture Science for Mar 22 - Neanderthal in the Family

Big Picture Science - Neanderthal in the Family

Back off, you Neanderthal! It sounds as if you’ve just been dissed, but maybe you should take it as a compliment. Contrary to common cliches, our Pleistocene relatives were clever, curious, and technologically inventive. Find out how our assessment of Neanderthals has undergone a radical rethinking, and hear about the influence they have as they live on in our DNA. For example, some of their genes have a strong association with severe Covid 19 infection. Plus, how Neanderthal mini-brains grown in a lab will teach us about the evolution of Homo sapiens.

Big Picture Science for Mar 15 - DecodeHer

Big Picture Science - DecodeHer

They were pioneers in their fields, yet their names are scarcely known – because they didn’t have a Y chromosome.  We examine the accomplishments of two women who pioneered code breaking and astronomy during the early years of the twentieth century and did so in the face of social opprobrium and a frequently hostile work environment.

Henrietta Leavitt measured the brightnesses of thousands of stars and discovered a way to gauge the distances to galaxies, a development that soon led to the concept of the Big Bang.

Elizabeth Friedman, originally hired to test whether William Shakespeare really wrote his plays, was soon establishing the science of code breaking, essential to success in the two world wars.

Also, the tech industry is overwhelmingly male. Girls Who Code is an initiative to redress the balance by introducing girls to computer programming, and encouraging them to follow careers in tech.

Guests:

• Jason Fagone – Author of “The Woman Who Smashed Codes: A True Story of Love, Spies, and the Unlikely Heroine Who Outwitted America’s Enemies”
• Lauren Gunderson – Playwright of Silent Sky, which is being performed all over the world, form the First Folio Theatre to the Repertory Philippines

Big Picture Science for Feb 22 - Creature Discomforts

 

Big Picture Science - Creature Discomforts

(REPEAT) - Okay you animals, line up: stoned sloths, playful pandas, baleful bovines, and vile vultures. We’ve got you guys pegged, thanks to central casting.

Or do we? Our often simplistic view of animals ignores their remarkable adaptive abilities. Stumbly sloths are in fact remarkably agile and a vulture’s tricks for thermoregulation can’t be found in an outdoors store.

Our ignorance about some animals can even lead to their suffering and to seemingly intractable problems. The South American nutria was brought to Louisiana to supply the fur market. But the species got loose and tens of millions of these rodents are destroying the environment. It literally has a bounty on its tail.

Hear about research that corrects a menagerie of misunderstandings about our fellow furry, feathered, and scaly animals, and how getting over ourselves to know them better can have practical benefits. Will you still recoil from termites if you learn that they are relevant to the future of robots, global warming, and smart design?

Guests:

• Lucy Cooke – Zoologist, broadcaster and author of “The Truth About Animals: Stoned Sloths, Lovelorn Hippos, and Other Tales from the Wild Side of Wildlife”
• Chris Metzler – Co-director and producer of the film Rodents of Unusual Size

Big Picture Science - Granting Immunity

(REPEAT) “Diversity or die” could be your new health mantra. Don’t boost your immune system, cultivate it! Like a garden, your body’s defenses benefit from species diversity.  Find out why multiple strains of microbes, engaged in a delicate ballet with your T-cells, join internal fungi in combatting disease. Plus, global
ecosystems also depend on the diversity of its tiniest members; so what happens when the world’s insects bug out?'

Guests:

• Matt Richtel – Author, most recently, of “An Elegant Defense: The Extraordinary New Science of The Immune System”
• Rob Dunn – Biologist and professor in the Department of Biological Sciences at North Carolina State University. Author of “Never Home Alone”

Big Picture Science for Feb .01 - Iron, Coal, WoodBig Picture Science for Feb .01 - Iron, Coal, Wood

Big Picture Science - Iron, Coal, Wood

Maybe you don’t remember the days of the earliest coal-fired stoves. They changed domestic life, and that changed society. We take you back to that era, and to millennia prior when iron was first smelt, and even earlier, when axe-handles were first fashioned from wood, as we explore how three essential materials profoundly transformed society.

We were once excited about coal’s promise to provide cheap energy, and how iron would lead to indestructible bridges, ships, and buildings. But they also caused some unintended problems: destruction of forests, greenhouse gases and corrosion. Did we foresee where the use of wood, coal, and iron would lead? What lessons do they offer for our future?

Guests:

• Jonathan Waldman – Author of Rust: The Longest War.
• Ruth Goodman – Historian of British social customs, presenter of a number of BBC television series, including Tudor Monastery Farm, and the author of The Domestic Revolution: How the Introduction of Coal into Victorian Homes Changed Everything.

Big Picture Science for Jan. 25 - Sketpic Check: Shared Reality

 

Big Picture Science - Sketpic Check: Shared Reality

One of the many shocking aspects of the Capitol attack was that it revealed how thoroughly the nation had cleaved into alternate realities. How did we get to this point? How did misinformation come to create beliefs embraced by millions?

In this episode, experts in social media, cults, and the history of science join us for a discussion about how these alternative realities formed, why people are drawn to them, and the benefits of a shared reality.

Guests:

• Joan Donovan – Research Director of the Shorenstein Center on Media, Politics and Public Policy in the John F. Kennedy School of Government at Harvard University, and leader of the Technology and Social Change Project.
