Thousands of years ago, people crossed a land bridge from Siberia to Western Alaska and dispersed southward into what we now call the Americas. The story of exactly when that was, how they did it, and who they were has fascinated us for a long time as excavations have uncovered pieces of those stories. University of Kansas Associate Professor of Anthropology Jennifer Raff joins us to talk about her book "Origin: A Genetic History of the Americas", digging into the ways modern genetics is being used to help us understand the history of people dispersing across the Americas. Along the way we learn more about how scientists have mis-stepped in their interactions with Indigenous people, and how new partnerships are being created to more respectfully investigate this history.

Give a cluck about chickens. The most popular meat actually has a 3,500 year history of cockfighting, backyard keeping, incubation invention, and a lot of scrambled eggs. And now, people are keeping them in their backyards as pets. How did we get here, and what changes have we made to the bird formerly known as the Asian Jungle Fowl? We're talking with Tove Danovich, author of the new book Under the Henfluence: Inside the World of Backyard Chickens and the People Who Love Them.

Sea creatures do so many things that astound us. They regrow and regenerate, they incubate eggs for years without ever eating a morsel. They can be one big individual one moment, and a multicelled colony the next. And writers like Sabrina Imbler don't see these differences from us as alien, but as jumping off points to explore selfhood, development, life and death in their new book; How Far The Light Reaches: A Life in Ten Sea Creatures.

In the past 120 years, physicists have revamped our understanding of matter — of everything that makes up the world. This week on the show, particle physicist Suzie Sheehy takes us on a tour through a cosmos of physics experiments that have revealed the nature of the atom and unveiled particles that exist outside of it. We’ll hear the tales of adventurous experiments and intrepid experimenters, including ones who didn’t receive their due. And along the way, we’ll learn about the ways that particle physics touches our everyday lives.

In January 2020 a race began to identify, control, and understand a novel coronavirus that quickly spread around the world creating a global pandemic. In his most recent book "Breathless: The Scientific Race to Defeat a Deadly Virus", writer David Quammen takes us back to those first days, weeks, months and years, putting us behind the shoulders of some of those first scientists as they try to reckon with the new Covid-19 virus. This week, we learn more about his experiencing of writing about the pandemic during the pandemic, how information about the virus spread through the scientific community, how the virus first mutated, and dig into the sometimes controversial search for Covid's origins during the first few years of the pandemic.

Humans are musical. Really, really musical. But why? What is it for, how did it come about, and what do we get from it? Let's get between the science and the hype (Mozart is not going to make you smarter) with Adriana Barton and her book: Wired for Music: A search for Health and Joy through the Science of Sound.

On this week’s show, we’re getting emotional. Our guest, neuroscientist Dean Burnett, talks about his new book Emotional Ignorance. He shares how the experience of his father’s death during covid prompted him to take on his emotions by writing about them. We talk about the sad, such as why people cry, but also travel across a wide range of emotions including strange emotional experiences such as nightmares. And we dive into the complexity of emotions, from defining them to how they arise in the brain and connections with the body.

Let's talk about sex, baby. Let's talk about birds and bees. Let's talk about all the slime molds and the algae that can be, let's talk about sex. This week we are talking about the history of sex, where it came from, what it is, who has it, and why people are always trying to tell others they are not allowed to do it. We're getting down and dirty with Rachel Feltman and their new book, Been There, Done That: A Rousing History of Sex.

John Dupuis and Joanne Manaster join host Rachelle Saunders in what might be our most favourite and longest-running December tradition: science book recommendations! We've brought our book mavens back to talk about their 2022 science book highlights and give us a sneak peak at what they're looking forward to reading next year.

As always, we've got our companion blog post ready with the full book list (plus some extras) with links to Amazon where you can find more information. Happy reading!

It's that time of year when Rachelle spends far too much time finding strange and wonderful new clocks, Bethany adds more mugs to her collection, and together we spend some time embracing our inner holiday-consumer and getting excited about lots of wonderful, delightful, charming and (sometimes) weird things you might get the geeks in your life.

As always, you can find a blog post companion to this episode with links to everything we discussed in this episode. And if that's still not enough to satisfy your nerdy gift-giving needs, you can always check out our full Bookshelf here, or take a look through our news archive for the book and gift lists from years past.

Keep an eye out for our annual book-buying guide, which will come out in a couple of weeks!
