Amazing Amazonia

The Amazon is often described as an ecosystem under dire threat due to climate change and deliberate deforestation. Yet there is still considerable hope that these threats can be mitigated. In the face of these threats, indigenous conservationists are attempting to strike a balance between tradition and preserving Amazonia. Meanwhile, two river journeys more than 100 years apart – one by a contemporary National Geographic reporter and another by “The Lewis and Clark of Brazil”— draw attention to the beauty and diversity of one of the world’s most important ecosystems. Guests: Cynthia Gorney – Contributing writer at the National Geographic Society, former bureau chief for South America at The Washington Post Larry Rohter – Reporter and correspondent in Rio de Janeiro for fourteen years for Newsweek and as The New York Times bureau chief. Author of Into the Amazon: The Life of Cândido Rondon, Trailblazing Explorer, Scientist, Statesman, and Conservationist João Campos-Silva – Brazilian researcher and conservationist, and cofounder of Instituto Jura, a conservation organization. His work, along with that of other conservationists, is featured in the National Geographic issue devoted to the Amazon.

A thousand years ago, most people didn’t own a single book. The only way to access knowledge was to consult their memory. But technology – from paper to hard drives – has permitted us to free our brains from remembering countless facts. Alphabetization and the simple filing cabinet have helped to systematize and save information we might need someday. But now that we can Google just about any subject, have we lost the ability to memorize information? Does this make our brains better or worse? Guests: Judith Flanders – Historian and author, most recently of A Place for Everything: The Curious History of Alphabetical Order Craig Robertson – Professor of Media Studies, Northeastern University and author of The Filing Cabinet: A Vertical History of Information David Eagleman – Neuroscientist and author, Stanford University Originally aired October 11, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

How Hot is Too Hot?*

Extreme heat is taking its toll on the natural world. We use words like “heat domes” and “freakish” to describe our everyday existence. These high temperatures aren’t only uncomfortable - they are lethal to humans, animals, and crops. In search of an answer to our episode’s question, we discuss the dilemma of an ever-hotter world with an author who has covered climate change for more than twenty years. Guest: Jeff Goodell – author of “The Heat Will Kill You First: Life and Death on a Scorched Planet.” Featuring music by Dewey Dellay and Jun Miyake *Originally aired October 2, 2023 Big Picture Science is part of the Airwave Media podcast network.

Platypus Crazy*

They look like a cross between a beaver and a duck, and they all live Down Under. The platypus may lay eggs, but is actually a distant mammalian cousin, one that we last saw, in an evolutionary sense, about 166 million years ago. Genetic sequencing is being used to trace that history, while scientists intensify their investigation of the habits and habitats of these appealing Frankencreatures; beginning by taking a census to see just how many are out there, and if their survival is under threat. Guests: Josh Griffiths – Senior Wildlife Ecologist at Cesaar Australia. Jane Fenelon – Research fellow, University of Melbourne Paula Anich – Professor of Natural Resources, Northland College Wes Warren – Professor of Genomics, University of Missouri Phoebe Meagher – Conservation Officer, Taronga Conservation Society, Australia Originally aired August 2, 2021 Featuring music by Dewey Dellay and Jun Miyake Big Picture Science is part of the Airwave Media podcast network.

Spotlight on SETI ep 2: Nathalie Cabrol

What is life? Even as the search for life in the universe evolves, surprisingly, there is no consensus on what life is. We must consider hunting for life not as we know it. The existence of extremophiles on Earth has broadened the types of environments in which we might look for life elsewhere in our solar system. And recent missions to dwarf planets has shown that our solar system is replete with the geology that might harbor biology. In this second episode, Shannon Geary talks with astrobiologist Nathalie Cabrol, the director of the Carl Sagan Center for Research at the SETI Institute about her early interest in astrobiology, meeting Carl Sagan, and the evolving definition of life.

Skeptic Check: String Theory

The idea that the universe is made of tiny vibrating strings was once the science theory du jour. String theory promised to unite the disparate theories describing particles and gravity, and many people, not just scientists, were optimistic that a theory of everything might be within our grasp. But here we are, many years later, and string theory doesn’t seem to have delivered on its initial promise. What happened? We consider the science around string theory in this episode of Skeptic Check. Guest: Brian Greene – Physicist and mathematician at Columbia University, and author of The Elegant Universe: Superstrings, Hidden Dimensions, and the Quest for the Ultimate Theory.

We'll Always Have Parasites

Imagine tapeworms longer than the height of an adult human. Or microbes that turn their hosts into zombies. If the revulsion they induce doesn’t do it, the sheer number of parasites force us to pay attention. They are the most abundant form of animal life on Earth. Parasites can cause untold human suffering, like those that cause African River Blindness or Lyme disease, but their presence is also a sign of a health ecosystem. A parasitologist whose lab contains the largest parasite collection in the world gives us the ultimate inside story about these organisms. Guest: Scott Gardner - curator of parasites in the H.W. Manter Laboratory of Parasitology at the University of Nebraska State Museum, one of the largest collections of parasites in the world, and professor of biological sciences at University of Nebraska. Co-author of Parasites: The Inside Story. Featuring music by Dewey Dellay and Jun Miyake Originally aired July 31, 2023 Big Picture Science is part of the Airwave Media podcast network.

Measure For Measure

Whether in miles or pounds, meters or kilograms, we take daily measure out our lives. But how did these units ever come to be, and why do we want to change them? From light-years to leap seconds, we look at the history of efforts to quantify our lives and why there’s always room for greater precision. Plus, we debate the virtues of staying imperial measurements vs. going metric. Guest: James Vincent - Author of Beyond Measure, the Hidden History of Measurement Featuring music by Dewey Dellay and Jun Miyake Originally aired March 24, 2023 Big Picture Science is part of the Airwave Media podcast network.
