We’re all affected by the Covid-19 pandemic, and that includes Big Picture Science. But if, in this distressing situation you can help out, we hope you’ll do so by clicking the “Support the Show” button below. That will allow us to continue bringing you new episodes, and to spotlight the science of the pandemic as well as all that’s new and notable in other research areas.

Oh, and if you’re already a regular donor, we hope you’ll consider giving a bit more in these trying times.

Thanks!

Think you’re some kind of expert? Join the club. It’s one thing to question authority; another to offer up your untrained self as its replacement. Rebellion may be a cherished expression of American individualism, but, from sidelining Dr. Fauci to hiding public health data, find out what we lose when we silence health experts and “go with our gut” during a pandemic. Plus, from ancestors to algorithms: how we’ve replaced credentialed experts with sketchy web sites and social media posts.

Guests:

  • Charles Piller – Investigative reporter for Science magazine
  • Alison Galvani – Epidemiologist and Director of the Center for Infectious Disease Modeling and Analysis, at Yale University 
  • Tom Nichols – Professor, international affairs, U.S. Naval War College, and author of “The Death of Expertise: The Campaign Against Established Knowledge and Why it Matters”
  • Alex Bentley – Anthropologist, University of Tennessee and author of “The Acceleration of Cultural Change: From Ancestors to Algorithms”

Something in the Air
Notice anything different?

Inhale. Now exhale. Notice anything different? Our response to the virus is changing the air in unexpected ways. A pandemic-driven pause on travel has produced clear skies and a world-wide air quality experiment. And a new study reveals that hundreds of tons of microplastics are raining down on us each day. 

But we can improve the quality of the breaths we do take; engineers have devised a high-tech mask that may kill coronavirus on contact. Plus, although you do it 25,000 times a day, you may not be breathing properly. Nose-breathing vs mouth breathing: getting the ins-and-outs of respiration.

Some dogs and cats have become sick with COVID. But it’s not just domestic critters that are vulnerable: zoo animals have fallen ill too. There’s more strange news about the pandemic, for example scientists who track the coronavirus in our sewage, and computer models that show that flushing the toilet can launch persistent, pathogenic plumes into the room. And scientists have warned the WHO that infectious virus remains airborne. Also, how a shortage of glass vials could delay the deployment of a vaccine.

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.

(repeat)  Your cat is smart, but its ability to choreograph a ballet or write computer code isn’t great.  A lot of animals are industrious and clever, but humans are the only animal that is uniquely ingenious and creative. 

Neuroscientist David Eagleman and composer Anthony Brandt discuss how human creativity has reshaped the world. Find out what is going on in your brain when you write a novel, paint a watercolor, or build a whatchamacallit in your garage.

But is ins加速器app claim on creativity destined to be short-lived?  Why both Eagleman and Brandt are prepared to step aside when artificial intelligence can do their jobs.

Laughing rats, sorrowful elephants, joyful chimpanzees.  The more carefully we observe, and the more we learn about animals, the closer their emotional lives appear to resemble our own.  Most would agree that we should minimize the physical suffering of animals, but should we give equal consideration to their emotional stress?  Bioethicist Peter Singer weighs in. Meanwhile, captivity that may be ethical: How human-elephant teamwork in Asia may help protect an endangered species.

Guests:

  • Frans de Waal - Primatologist and biologist at Emory University; author of “Mama’s Last Hug: Animal Emotions and What They Tell Us About Ourselves.”  Watch the video of Mama and Jan Van Hooff.

Radioactive Bookkeeping of Carbon Emissions

A new sampling method uses carbon-14 to single out which carbon dioxide molecules in the atmosphere derive from fossil fuels. The method could help track emissions goals for climate mitigation.
