  • 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

    New tech spawns new anxieties, says scientist and philosopher Grady Booch, but we don’t need to be afraid an all-powerful, unfeeling AI. Booch allays our worst (sci-fi induced) fears about superintelligent computers by explaining how we’ll teach, not program, them to share our values.

  • How we explore unanswered questions in physics | James Beacham

    James Beacham looks for answers to the most important open questions of physics using the biggest science experiment ever mounted, CERN’s Large Hadron Collider. In this fun and accessible talk about how science happens, Beacham takes us on a journey through extra-spatial dimensions in search of undiscovered fundamental particles (and an explanation for the mysteries of gravity) and details the drive to keep exploring.

  • Why Earth may someday look like Mars | Anjali Tripathi

    Every minute, 400 pounds of hydrogen and almost 7 pounds of helium escape from Earth’s atmosphere into outer space. Astrophysicist Anjali Tripathi studies the phenomenon of atmospheric escape, and in this fascinating and accessible talk, she considers how this process might one day (a few billion years from now) turn our blue planet red.
