  • How do we fix recycling?

    Jun 22 2022

    Tai tries to do his part by recycling whenever he can. But it turns out just tossing stuff into the blue bin doesn't do a whole lot: less than 10 percent of our plastic waste actually gets recycled, with the rest either ending up in landfill, burned or shipped overseas! How did we get here? Tai turns to people looking for creative ways to tackle trash around the world, and learns how we can all be more mindful of what we decide to throw away. In this episode Tai talks to: - Calvin Lakhan, resea...more

  • Why do we laugh?

    Jun 15 2022

    Laughing makes us feel real good, whether you’re in on the joke or not. But does it serve a specific purpose? Why do we find some jokes hilarious and others to be total groaners? In this episode, Tai peels the science and sociology of laughter down to its evolutionary roots. In this episode Tai talks to: - Sophie Scott, professor of cognitive neuroscience at University College London and stand-up comedian - Andrew Phung, actor, improv comedian and creator of the sitcom Run the Burbs

    Jun 08 2022

    So far, the only intelligent life we know of is right here on Earth — us! But could there be life on other planets just waiting to be discovered?

  • How do animals know where they’re going?

    Jun 01 2022

    We know birds can travel large distances day or night, rain or shine, even if they’ve never migrated before.

In this episode Tai talks to: - David Barrie, researcher and author of Supernavigators: Exploring the Wonders of How Animals Find Their Way - Ken Lohmann, biology professor at the University o...more

  • Why is math so hard to love?

  • Why do we love junk food so much?

    May 18 2022

    Pizza, chips, gummy worms and wings — these are a few of Tai’s favourite things! He just can’t get enough of their sugary, fatty, salty goodness, even though he knows they’re not exactly good *for* you. But why does he find those foods so irresistible in the first place? In this episode, Tai unravels the science behind our food cravings and how companies use it to formulate products that hook us in. In this episode Tai talks to: - Yanina Pepino, associate professor in the Department of Food Sci...more

  • How reliable are our memories?

    May 11 2022

    Whether they're happy, sad or the embarrassing kind we'd rather forget, memories play a big part in our lives. They shape our identities, help us connect with others and allow us to learn from our past. But can we trust that our memories are accurate? In this episode, Tai digs deep into how memory works in the brain, and enlists the help of experts to interpret a particularly scary childhood memory. In this episode Tai talks to: - Ayanna Thomas, professor of psychology at Tufts University - Ste...more

  • What can I do when I’m anxious?

    Apr 27 2022

From cows to cryptocurrency, Tai traces the evolution of money to see if its history can offer clues to where it’s headed next. In this episode Tai talks to: - Stephen McKeon, associate professor of finance at the University of Oregon - Gina...more

  • Can we keep eating meat without destroying the planet?

    Apr 20 2022

    To Tai, nothing beats cutting into a perfectly cooked steak or wolfing down a big, juicy cheeseburger. But lately he’s been paying more attention to the buzz around going meatless in the fight against climate change. “Plant-based” foods like beefless burgers and chickenless nuggets have made their way into grocery aisles and fast food chains. But are those actually better for the environment? What exactly is our appetite for meat doing to the planet? Tai investigates. In this episode Tai talks ...more

  • Tai’s back

  • Where is the internet?

    Mar 03 2021

    For Tai, the internet has always been there, and it's hard to imagine life without it. It seems almost like it's everywhere, all at once, like magical little clouds filled with information above us.

In this episode Tai talks to: - Nicole Starosielski, Associate Professor of Media, Culture, and Communication at New York Uni...more

  • How else can we power the planet?

    Feb 24 2021

    Nothing on our planet could function without pooower! Even though energy is all around us, harnessing that energy and turning it into power is a massive challenge.

  • Why are viruses so good at what they do?

    Jan 20 2021

They’re in you, they’re on you and, in fact, there are more viruses in the world than there are stars in the sky. So why aren’t we sick all the time? In this episode Tai looks at how viruses work, how they travel, and the ways in which they shape our lives—both bad and good.
