This week: new research into using nanoparticles and programmable magnets to clean your teeth; a potentially breakthrough study on a drug for Alzheimer's disease featuring the first positive trial ever for a disease of aging; recapping NASA’s recent Double Asteroid Redirection Test mission; and a look into how much control you actually have over what Youtube decides to show you.

This week we talk to theoretical physicist and cosmologist Antonio Padilla about his new book Fantastic Numbers and Where to Find Them. It’s a book about nine unusual numbers that, once understood, can help you grasp how the universe actually works—from black holes, to gravity, to the passing of time itself.

This week we talk to Alexandra Horowitz from the Dog Cognition Lab at Barnard College about her new book The Year of the Puppy: How Dogs Become Themselves. Horowitz’s book examines how a dog’s brain works and develops—how it dramatically changes during their first 12 months of life, her shifting perspective on dog cognition, and the vast differences between humans and dogs that we tend to overlook.Support the show: https://www.patreon.com/inquiringminds

This week we talk to cognitive neuroscientist Chantel Prat about her new book The Neuroscience of You: How Every Brain is Different and How to Understand Yours.

On the show this week we’re joined by naturalist, author, and returning guest Sy Montgomery. Throughout her career, Montgomery has repeatedly shown an incredible ability to understand, befriend, and interact with animals. We last heard from her in episode #128 where she talked about her 2016 book The Soul of an Octopus, but she’s written about everything from tigers to snakes to hummingbirds. In this episode we explore her latest book, where she covers her perhaps most challenging animal yet,...

On the show this week we’re joined by Brian Butterworth, emeritus professor of cognitive neuropsychology and author of the new book Can Fish Count? What Animals Reveal About Our Uniquely Mathematical Minds. He’s spent his career looking at the genetics and neuroscience of mathematical ability—and not just in humans.  Support the show: https://www.patreon.com/inquiringminds See omnystudio.com/listener for privacy information.

How do you feel fear and be creative anyway? How is letting your mind wander key to coming up with, and following through on, creative ideas? Returning to the show this week is journalist Matt Richtel, winner of the 2010 Pulitzer Prize for National Reporting for a series on distracted driving, and author of numerous books. His latest book, Inspired: Understanding Creativity: A Journey Through Art, Science, and the Soul, is devoted to a deeper understanding of creativity and he joins us this...

How do you define how painful something is? On the show this week we welcome back physician, writer, and clinical researcher Haider Warraich to talk about his new book The Song of Our Scars: The Untold Story of Pain. Warraich explores the idea that far from being something objective and easily defined, pain is complex, misunderstood, and culturally influenced. The book delves into the history of pain and explains how our understanding of it has been “shaped not just by science but by politics...

This week we’re joined by Benjamin Ehrlich, author of The Brain in Search of Itself: Santiago Ramón y Cajal and the Story of the Neuron. It’s a book about the discoveries and life of Spanish neuroscientist Santiago Ramón y Cajal, who has been called the ‘father of modern neuroscience.’  While today relatively unknown outside of his field, Cajal’s discoveries about the brain changed the field of neuroscience forever. In 1906 he won a Nobel Prize for his pioneering work on neurons, which he...

This week, we examine a recent discovery that certain types of cancer cells may allow us to better understand how cells adapt to the intracellular environment (and explain what the intracellular environment is). Indre discusses how she and her students have recently been working on methods of measuring creativity. And we look at some new research focusing on the hunting method used by archerfish in order to study aspects of visual perception. Inquiring Minds website Support the show:...

During the pandemic, one thing we’ve had a little more of--at least sometimes--is time. Time to panic and stress and worry, but also time to think and reflect. This week, in the spirit of reflection, we’re revisiting a conversation with theoretical physicist Sean Carroll recorded back in 2016. At the time he had just written a book called The Big Picture: On the Origins of Life, Meaning, and the Universe Itself, which explores questions about purpose and belief and meaning. Today, in 2022,...

We can never know what it’s like for a bat to be a bat. Or even if there is something that it is like for a bat to be a bat. But if there is something, we would speculate that the bat has some kind of consciousness or sentience. That’s the argument Jackie Higgins makes in her new book Sentient: How Animals Illuminate the Wonder of Our Human Senses, in which she takes us on a deep dive into the sensory experience of many different animals, from fish to owls, to moles, to cheetahs. Jackie is a...

One of the fascinating things about neuroscience is that it gives us something tangible to study in the biology of the brain that can tell us something about the mind, which is so intangible. But what if that approach leaves us missing a big piece of the puzzle? What if the mind actually extends far beyond the biology of the body? Today, Indre is joined by Annie Murphy Paul, an acclaimed science writer, who makes this claim in her new book The Extended Mind: The Power of Thinking Outside the...

More than a hundred million people watched the Netflix movie Don’t Look Up, which focused on our fear that something could crash into our planet from space and destroy it. But what if things that come from space don’t just have the potential to destroy life but also to create it? That’s Greg Brennecka’s argument, and he joins Indre on today’s episode to talk all about it. Greg is a staff scientist and cosmochemist at Lawrence Livermore National Laboratory, whose research has appeared in...

In this week’s episode, Indre revisits a topic that has been covered a couple of times on the podcast: addiction.

The holidays are a time for storytelling, and what better story to re-experience than the greatest one of all: the history of the universe and life on Earth. In today’s episode, Indre is joined by writer and editor Henry Gee to discuss this most epic of all stories and how it’s depicted in Henry’s new book, A (Very) Short History of Life on Earth. Henry is a senior editor at Nature and the author of several books, including Jacob’s Ladder, In Search of Deep Time, and The Accidental Species....

In this episode, Emily Willingham joins Indre to talk about tailoring the brain, a subject on which she’s an expert and about which she writes extensively in her book The Tailored Brain: From Ketamine, to Keto, to Companionship, A User's Guide to Feeling Better and Thinking Smarter. Emily is a journalist, a science writer, the author of previous books, including Phallacy: Life Lessons from the Animal Penis, a coauthor of The Informed Parent: A Science-Based Resource for Your Child's First...

In today's up to date episode, Adam Bristol is back to highlight three scientific papers that have caught his eye lately. The first two are about our evolutionary history of life on this planet, filling in some of the holes in the fossil record, and making some unexpected discoveries along the way. The third paper has us looking at potential biosecurity concerns in the distant future, which may actually arise earlier than expected given humans' exploration of planets. From the distant past to...

In early 2020, experts predicted the development of the COVID-19 vaccine would take 12 to 18 months.
