    Are life-saving medicines hiding in the world's coldest places? | Normand Voyer

    Are life-saving medicines hiding in the world's coldest places? | Normand Voyer

    Could the next wonder drug be somewhere in Canada's snowy north? Take a trip to this beautiful, frigid landscape as chemist Normand Voyer explores the mysterious molecular treasures found in plants thriving in the cold. These scarcely investigated organisms could hold immense medical promise, he says – so long as we work quickly enough to discover them.

    What to do when there's a polar bear in your backyard | Alysa McCall

    What to do when there's a polar bear in your backyard | Alysa McCall

    As Arctic ice melts, polar bears are being forced on land -- and they're hungry. With the apex predators frequently turning to human junkyards for a snack, northern towns have had to get creative in order to keep both their people and wildlife safe. Biologist and conservationist Alysa McCall shares lessons from the field on how to safely navigate contact with these magnificent animals and plan for a future where climate change forces us all a little closer.

    The fantastically weird world of photosynthetic sea slugs | Michael Middlebrooks

    The fantastically weird world of photosynthetic sea slugs | Michael Middlebrooks

    Meet the fantastically colorful and astonishingly adaptable sea slugs that found a way to photosynthesize (or create energy from sunlight) like plants. Diving deep into these often overlooked creatures, invertebrate zoologist Michael Middlebrooks introduces the solar-powered slugs that lost their shells -- but gained the ability to directly harness the power of the sun.

    Where does your sense of self come from? A scientific look | Anil Ananthaswamy

    Where does your sense of self come from? A scientific look | Anil Ananthaswamy

    Our memories and bodies give us clues about who we are, but what happens when this guidance shifts? In this mind-bending talk, science writer Anil Ananthaswamy shares how the experiences of "altered selves" -- resulting from schizophrenia, Alzheimer's, foreign limb syndrome or other conditions -- shed light on the constructed nature of identity. He breaks down where our sense of self comes from and invites us to challenge our assumptions about who we are, with the aim of building a better you and a better world.

    Can we feed ourselves without devouring the planet? | George Monbiot

    Can we feed ourselves without devouring the planet? | George Monbiot

    Farming is the worst thing humanity has ever done to the planet, says journalist George Monbiot. What's more: the global food system could be heading toward collapse. Detailing the technological solutions we need to radically reshape food production -- from lab-grown, protein-rich foods to crops that don't require plowing -- Monbiot shares a future-focused vision of how humanity could feed itself without destroying the planet.

    How to harness the ancient partnership between forests and fungi | Colin Averill

    How to harness the ancient partnership between forests and fungi | Colin Averill

    If we want to better understand the environment and combat climate change, we need to look deep underground, where diverse microscopic fungal networks mingle with tree roots to form symbiotic partnerships, says microbiologist Colin Averill. As we learn more about which of these fungi are most beneficial to forest health, we can reintroduce them into the soil -- potentially enhancing the growth and resilience of carbon-trapping trees and plants. Hear more about the emerging science aiming to supercharge forest ecosystems, one handful of soil at a time.
