Big Picture Science for Dec. 16, 2024 - 2024: Our Space Odyssey

Big Picture Science - 2024: Our Space Odyssey

This year has been a spectacular one for celestial phenomena. The northern lights delighted in unexpected ways while a total solar eclipse cast a shadow across North America. Those events were enough to make it a memorable year, but 2024 also shook up our understanding of the universe. A new reading of Voyager 2 data may explain Uranus’s weird magnetic field. And the impressive James Webb Space Telescope has detected an early and incredibly distant galaxy. Join us in our look back at some of the top space news from 2024.

Guests:

• Andrew Fraknoi – Professor of Astronomy at the Fromm Institute at the University of San Francisco and SETI board member
• Jamie Jasinski - space plasma physicist for the NASA Jet Propulsion Laboratory, and author of a recent paper re-examining data from the Voyager 2 mission, published in Nature.

Big Picture Science for Dec. 09, 2024 - A Real Gas

Big Picture Science - A Real Gas

Just because something is invisible doesn’t mean it isn’t there. We can’t see gases in our atmosphere, such as carbon dioxide, oxygen, and nitrogen, but we benefit from their presence with every breath we take. From the bubbles that effervesce in soda to the vapors that turn engines, gases are part of our lives. They fill our lungs, give birth to stars, and… well, how would we spot a good diner without glowing neon? In this episode, a materials scientist shares the history of some gaseous substances that we don’t usually see, but that make up our world.

Guest:

• Mark Miodownik – Professor of materials and society at the University College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”

Big Picture Science for Dec. 01, 2024 - Going Multicellular

 

 

Big Picture Science - Going Multicellular

REPEAT
Imagine life without animals, trees, and fungi. The world would look very different. But while the first life was surely single-celled, we don’t know just how it evolved to multicellular organisms. Two long-term experiments hope to find out, and one has been running for more than 35 years. Hear about the moment scientists watched evolution take off in the lab, and how directed evolution was used to create a multicellular organism. Also, how single embryonic cells become humans, and what all of this says about the possibility of life on other worlds.

Guests:

• Jeff Barrick – molecular scientist at the University of Texas at Austin where his lab oversees the Long-Term Evolution Experiment that’s been running since 1988.
• Will Ratcliff – an evolutionary biologist at Georgia Institute of Technology
• Ben Stanger – cancer researcher, professor of medicine and developmental biology at the University of Pennsylvania and author of “From One Cell: A Journey into Life’s Origins and the Future of Medicine.”
• Joseph L. Graves – evolutionary biologist and geneticist at North Carolina Agricultural and Technical State University and author of “A Voice in the Wilderness: A Pioneering Biologist Explains How Evolution Can Help Us Solve Our Biggest Problems.”

Big Picture Science for Nov. 25, 2024 - Skeptic Check: Near Death Experiences

Big Picture Science - Skeptic Check: Near Death Experiences

REPEAT
Near death experiences can be profound and even life changing. People describe seeing bright lights, staring into the abyss, or meeting dead relatives. Many believe these experiences to be proof of an afterlife.

But now, scientists are studying these strange events and gaining insights into the brain and consciousness itself. Will we uncover the scientific underpinning of these near-death events?

Guests:

• Steve Paulson - executive producer of To the Best of Our Knowledge for Wisconsin Public Radio
• Sebastian Junger - journalist, filmmaker and author of “The Perfect Storm: A True Story of Men Against the Sea”
• Christoph Koch - neuroscientist at the Allen Institute in Seattle and chief scientist of the Tiny Blue Dot Foundation in Santa Monica California

Big Picture Science for Nov. 18, 2024 - Beyond the Periodic Table

 

Big Picture Science - Beyond the Periodic Table

You interact with about two-thirds of the elements of the periodic table every day. Some, like carbon, oxygen, and nitrogen, make up our bodies and the air we breathe. Yet there is also a class of elements so unstable they can only be made in a lab. These superheavy elements are the purview of a small group stretching the boundaries of chemistry. Can they extend the periodic table beyond the 118 in it now? Find out scientists are using particle accelerators to create element 120 and why they’ve skipped over element 119. Plus, if an element exists for only a fraction of a second in the lab, can we still say that counts as existing?

Guests:

• Mark Miodownik – professor of materials and society at the University of College London and the author of “It’s a Gas: The Sublime and Elusive Elements That Expand Our World.”
• Kit Chapman – Science historian at Falmouth University, author of “Superheavy; Making and Breaking the Periodic Table.”
• Jennifer Pore – Research Scientist of Heavy Elements at Lawrence Berkeley National Laboratory.

Big Picture Science for Nov. 11, 2024 - Amazing Amazonia

Big Picture Science - 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.

Big Picture Science for Nov. 04, 2024 - Fuhgeddaboudit

 

Big Picture Science - Fuhgeddaboudit

REPEAT
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

Big Picture Science for Oct.. 28, 2024 - How Hot is Too Hot?

 

Big Picture Science - How Hot is Too Hot?

REPEAT
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.”

Big Picture Science for Oct.. 21, 2024 - Platypus Crazy

Big Picture Science - Platypus Crazy

REPEAT
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

Big Picture Science for Oct.. 14, 2024 - Skeptic Check: String Theory

Big Picture Science - 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.

Big Picture Science for Oct.. 07, 2024 - We’ll Always Have Parasites

 

Big Picture Science - We’ll Always Have Parasites

REPEAT

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.

Big Picture Science for Sept. 30, 2024 - Measure For Measure

 

 

 

 

 

Big Picture Science - Measure For Measure

REPEAT
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

Big Picture Science for Sept. 16, 2024 - Cold Comfort

Big Picture Science - Cold Comfort

Another scorching summer has us blasting the AC and grabbing a chilled drink. Air conditioning and refrigeration may beat the heat, but they also present a dilemma. The more we use them, the more greenhouse gases we emit, the hotter the planet becomes, and the more we require artificial cooling.  Can we escape this feedback loop?  We look at the origins of these chilling technologies, tour the extensive chain of cold that keeps food from perishing, and consider how a desert city like Phoenix could not exist without AC.

Guests:

• Nicola Twilley – co-host of the Gastropod podcast, a contributing writer at The New Yorker, and the author of  “Frostbite: How Refrigeration Changed Our Food, Our Planet, and Ourselves”
• Erik Morrison – Chief cooling engineer at Transaera, Somerville, Massachusetts
• Stan Cox – Lead scientist at the Land Institute, author of “Losing Our Cool: The Uncomfortable Truths about our Air-Conditioned World”

Big Picture Science for Sept. 09, 2024 - Shipwrecks

Big Picture Science - Shipwrecks

Shipwrecks are scenes of tragedy, but they are also bits of history frozen in time that can provide insights into events and ideas from long ago. That is, if we can find them.  From an 11th century Viking sailing ship to a WW II era British cargo ship with a mailbag of letters onboard amazingly preserved, an underwater archeologist takes us on a deep dive into history.

Guest:

• David Gibbins - underwater archeologist, novelist, and the author of nonfiction, including his latest book, “The History of the World in Twelve Shipwrecks”
