    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.

    The wheat field that could change the world | Guntur V. Subbarao

    Crop physiologist Guntur V. Subbarao and his team have developed an antibiotic-infused strain of wheat that naturally combats harmful, fertilizer-eating bacteria -- a "monster" contributor to climate change. Learn more about how this breakthrough could once again revolutionize agriculture, increasing crop yields and protecting our planet at the same time.

    A virus-resistant organism -- and what it could mean for the future | Jason W. Chin

    A virus-resistant organism -- and what it could mean for the future | Jason W. Chin

    What if we could use the power of DNA to create a sustainable, circular economy? In a talk about breakthrough science, synthetic biologist Jason W. Chin describes his team's work rewriting the genetic blueprint of cells to create a virus-resistant organism -- the largest synthetic genome ever made and a first step towards reimagining what life can become. Learn more about how this advancement could lay the groundwork for the sustainable factories of the future, capable of producing plastics, antibiotics and more.

    How green hydrogen could end the fossil fuel era | Vaitea Cowan

    How green hydrogen could end the fossil fuel era | Vaitea Cowan

    As climate change accelerates, finding clean alternatives to fossil fuels is more urgent than ever. Social entrepreneur Vaitea Cowan believes green hydrogen is the answer. Watch as she shares her team's work mass producing electrolyzers -- devices that separate water into its molecular components: hydrogen and oxygen -- and shows how they could help make green, carbon-free fuel affordable and accessible for everyone. "This is how we end the fossil fuel era," Cowan says.

    A giant Jurassic sea dragon, unearthed | Dean R. Lomax

    Among the dinosaurs, giant sea dragons roamed the ancient ocean. Millions of years later, paleontologist Dean R. Lomax and his team freed the remains of one of these colossal creatures from the Earth. Settle in to learn about the once-in-a-lifetime discovery of the 10-meter-long Rutland ichthyosaur: the largest and most complete ichthyosaur ever unearthed in Britain and one of the greatest finds in the country's paleontological history.
