Big Picture Science for Feb. 28, 2022 - Skeptic Check: 5G

 

 

Big Picture Science - Skeptic Check: 5G

5G, the latest mobile network standard, is coming. As new cell towers sprout around the world, do we know enough to confidently claim that this new technology is safe? After all, older networking standards relied on microwaves, radiation which has wavelengths of inches to a foot or so. 5G operates at much higher frequencies, with millimeter wavelengths.

Some are worried that being subjected to millimeter radiation could cause cancers. But what does science say? 5G: the promise and the perils.

Guests:

• Jon Samet – Pulmonary physician, epidemiologist, and dean of the Colorado School of Public Health.
• Claire Parkinson – Scientist, NASA’s Goddard Space Flight Center
• Bob Berman – Astronomer, regular contributor to Astronomy Magazine, and author of “Zapped: From Infrared to X-Rays, the Curious History of Invisible Light”
• David Ropeik – Retired Harvard instructor and author of several books about the psychology of risk perception.

Big Picture Science for Feb. 21, 2022 - Melting Down

Big Picture Science - Melting Down

Climate change isn’t waiting for us to act. We’ve missed several deadlines to mitigate the dangers of this existential threat, which suggests we prefer to avert our gaze rather than deal with the problem. It’s similar to the way society reacts to an incoming comet in the movie “Don’t Look Up!”

As a major Antarctic ice sheet shows signs of collapse, it’s no wonder we feel some “climate anxiety.” Can we leverage this emotion to spur action?  That, and where hope lies, in this episode.

Guests:

• Joellen Russell – Oceanographer and climate scientist at the University of Arizona
• Katie Mack – Professor of Theoretical Physics at North Carolina State University, and author of “The End of Everything (Astrophysically Speaking)”
• Jessica Tierney – Professor of Paleoclimatology at the University of Arizona

Big Picture Science for Feb. 14, 2022 - Iron, Coal, Wood

Big Picture Science - Iron, Coal, Wood

(REPEAT) 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.
• Roland Ennos – Professor of biological sciences at the University of Hull and author of The Age of Wood: Our Most Useful Material and the Construction of Civilization.

Big Picture Science for Feb. 7, 2022 - Skeptic Check: Do Your Own Research

Big Picture Science - Skeptic Check: Do Your Own Research

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.
• Nathan Ballantyne – Professor of Philosophy at Fordham University, in New York.
• David Dunning – Social psychologist and Professor of Psychology at the University of Michigan.
• Lee McIntyre – Research fellow at the Center for Philosophy and History at Boston University, author of “Post-Truth,” and “How to Talk to a Science Denier: Conversations with Flat Earthers, Climate Deniers, and Others Who Defy Reason.”

Big Picture Science for Jan. 31, 2022 - Bare Bones

Big Picture Science - Bare Bones

(REPEAT) You may not feel that your skeleton does very much. But without it you’d be a limp bag of protoplasm, unable to move.  And while you may regard bones as rigid and inert, they are living tissue.

Bones are also time capsules, preserving much of your personal history. Find out how evolutionary biologists, forensic anthropologists, and even radiation scientists read them.

And why won’t your dog stop gnawing on that bone?

Guests:

Big Picture Science for Jan. 17, 2022 - Testing Your Metal

Big Picture Science - Testing Your Metal

Catalytic converters are disappearing. If you’ve had yours stolen, you know that rare earth metals are valuable. But these metals are in great demand for things other than converters, such as batteries for electric cars, wind farms and solar panels.

We need rare earth metals to combat climate change, but where to get them? Could we find substitutes?

One activity that could be in our future: Deep sea mining. But it’s controversial. Can one company’s plan to mitigate environmental harm help?

Guests:

• Paul Dauenhauer - Professor of chemical engineering and material science at the University of Minnesota and a 2020 MacArthur Fellow
• Chris Leighton - Distinguished University Teaching Professor, Editor, Physical Review Materials, Dept. of Chemical Engineering and Materials Science, University of Minnesota

Big Picture Science for Jan. 10, 2022 - Into the Deep

Big Picture Science - Into the Deep

(Rereat) Have you ever heard worms arguing? Deep-sea scientists use hydrophones to eavesdrop on “mouth-fighting worms.” It’s one of the many ways scientists are trying to catalog the diversity of the deep oceans — estimated to be comparable to a rainforest.

But the clock is ticking. While vast expanses of the deep sea are still unexplored, mining companies are ready with dredging vehicles to strip mine the seafloor, potentially destroying rare and vulnerable ecosystems. Are we willing to eradicate an alien landscape that we haven’t yet visited?

Guests:

• Craig McClain - deep-sea and evolutionary biologist and ecologist, Executive Director of the Louisiana Universities Marine Consortium.
• Steve Haddock - senior scientist at the Monetary Bay Aquarium Research Institute, and co-author of a New York Times op-ed about the dangers of mining.
• Emily Hall - marine chemist at the Mote Marine Laboratory, Sarasota, Florida
• Chong Chen - deep sea biologist with the Japan Agency for Marine-Earth Science and Technology (JAMSTEC)

Big Picture Science for Jan. 3, 2022 - What’s a Few Degrees?

Big Picture Science - What’s a Few Degrees?

Brace yourself for heatwave “Lucifer.” Dangerous deadly heatwaves may soon be so common that we give them names, just like hurricanes. This is one of the dramatic consequences of just a few degrees rise in average temperatures.

Also coming: Massive heat “blobs” that form in the oceans and damage marine life, and powerful windstorms called “derechos” pummeling the Midwest.

Plus, are fungal pathogens adapting to hotter temperatures and breaching the 98.6 F thermal barrier that keeps them from infecting us?

Guests:

• Kathy Baughman McLeod – director and senior vice president of the Adrienne Arsht-Rockefeller Foundation Resilience Center at The Atlantic Council
• Pippa Moore – Marine ecologist at Newcastle University in the U.K.

Big Picture Science for Dec. 27, 2021 - Mycology Education

 

Big Picture Science - Mycology Education

(Repeat) Beneath our feet is a living network just as complex and extensive as the root systems in a forest. Fungi, which evolved in the oceans, were among the first to colonize the barren continents more than a half-billion years ago. They paved the way for land plants, animals, and (eventually) you.

Think beyond penicillin and pizza, and take a moment to consider these amazing organisms. Able to survive every major extinction, essential as Nature’s decomposers, and the basis of both ale and antibiotics, fungi are essential to life. And their behavior is so complex you’ll be wondering if we shouldn’t call them intelligent!

Guest:

• Merlin Sheldrake – Biologist and the author of Entangled Life: How Fungi Make our Worlds, Change our Minds and Shape our Futures.

Big Picture Science for Dec. 20, 2021 - Attack of the Mutants

Big Picture Science - Attack of the Mutants

The omicron variant is surging. More contagious than delta, omicron demonstrates how viruses use mutations to quickly adapt.

Mutations drive evolution, although most don’t do much. But occasionally a mutation improves an organism. Omicron, the latest in a string of variants, is bad for us, but good for the virus.

How mutation of viruses ensures their own survival while threatening ours, and the prospect of a universal vaccine that would protect us against all a viruses’ variants.

Guests:

• Robert Garry – Professor of microbiology and virologist in the Tulane University School of Medicine
• Kevin Saunders – Professor in the Duke University School of Medicine’s Human Vaccine Institute and professor of surgery

Big Picture Science for Dec. 06, 2021 - Skeptic Check: Identifying UAPs

Big Picture Science - Skeptic Check: Identifying UAPs

The Pentagon’s report on UAPs (Unidentified Aerial Phenomena) said nothing about the possibility that some might be alien spacecraft. Nonetheless, the report has generated heightened interest in figuring out what these UAPs are, and that interest extends to some scientists. We talk to two researchers who want an open and strictly scientific investigation of these phenomena. What should they do and what do they expect to find? And finally, will the possibility of alien visitors ever be resolved?

Guests:

• Jacob Haqq-Misra – Senior Research Investigator at the Blue Marble Space Institute of Science
• Ravi Kopparapu – Planetary scientist, NASA Goddard Space Flight Center

Big Picture Science for Nov. 29, 2021 - Talk the Walk

 

Big Picture Science - Talk the Walk

Birds and bees do it … and so do fish. In a discovery that highlights the adaptive benefits of walking, scientists have discovered fish that can walk on land. Not fin-flap their bodies, mind you, but ambulate like reptiles.

And speaking of which, new research shows that T Rex, the biggest reptile of them all, wasn’t a sprinter, but could be an efficient hunter by outwalking its prey.

Find out the advantage of legging it, and how human bipedalism stacks up. Not only is walking good for our bodies and brains, but not walking can change your personality and adversely affect your health.

Guests:

• Hans Larsson – Paleontologist and biologist, and Director of the Redpath Museum at McGill University in Montréal.
• Shane O’Mara – Neuroscientist and professor of experimental brain research at Trinity College Dublin. He is the author of “In Praise of Walking.”
