  • Why school should start later for teens | Wendy Troxel

    Teens don’t get enough sleep, and it’s not because of Snapchat, social lives or hormones — it’s because of public policy, says Wendy Troxel. Drawing from her experience as a sleep researcher, clinician and mother of a teenager, Troxel discusses how early school start times deprive adolescents of sleep during the time of their lives when they need it most.

  • How human noise affects ocean habitats | Kate Stafford

    Oceanographer Kate Stafford lowers us into the sonically rich depths of the Arctic Ocean, where ice groans, whales sing to communicate over vast distances — and climate change and human noise threaten to alter the environment in ways we don’t understand.

  • The biology of our best and worst selves | Robert Sapolsky

    How can humans be so compassionate and altruistic — and also so brutal and violent? To understand why we do what we do, neuroscientist Robert Sapolsky looks at extreme context, examining actions on timescales from seconds to millions of years before they occurred.

  • Science in service to the public good | Siddhartha Roy

    We give scientists and engineers great technical training, but we’re not as good at teaching ethical decision-making or building character. Take, for example, the environmental crisis that recently unfolded in Flint, Michigan — and the professionals there who did nothing to fix it.

  • A doctor’s case for medical marijuana | David Casarett

  • How early life experience is written into DNA | Moshe Szyf

  • What we don’t know about mother’s milk | Katie Hinde

    Breast milk grows babies’ bodies, fuels neurodevelopment, provides essential immunofactors and safeguards against famine and disease — why, then, does science know more about tomatoes than mother’s milk? Katie Hinde shares insights into this complex, life-giving substance and discusses the major gaps scientific research still needs to fill so we can better understand it.

  • A young inventor’s plan to recycle Styrofoam | Ashton Cofer

    From packing peanuts to disposable coffee cups, each year the US alone produces some two billion pounds of Styrofoam — none of which can be recycled. Frustrated by this waste of resources and landfill space, Ashton Cofer and his science fair teammates developed a heating treatment to break down used Styrofoam into something useful.
