  • 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

    Physician David Casarett was tired of hearing hype and half-truths around medical marijuana, so he put on his skeptic’s hat and investigated on his own. He comes back with a fascinating report on what we know and what we don’t — and what mainstream medicine could learn from the modern medical marijuana dispensary.

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

    His research suggests that biochemical signals passed from mothers to offspring tell the child what kind of world they’re going to live in, changing the expression of genes. “DNA isn’t just a sequence of letters; it’s not just a script.” Szyf says.

  • 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.

  • A robot that eats pollution | Jonathan Rossiter

    Meet the “Row-bot,” a robot that cleans up pollution and generates the electricity needed to power itself by swallowing dirty water. Roboticist Jonathan Rossiter explains how this special swimming machine, which uses a microbial fuel cell to neutralize algal blooms and oil slicks, could be a precursor to biodegradable, autonomous pollution-fighting robots.

  • Don’t fear superintelligent AI | Grady Booch
