Katie Hinde: What we don't know about mother's milk

09:59 minutes · Filmed Oct 2016 · Posted Mar 2017 · TEDWomen 2016

Breast milk grows babies' bodies, fuels neurodevelopment, provides essential immunofactors and safeguards against famine and disease -- why, then, does science know more about, say, tomatoes than about mother's milk? Katie Hinde shares insights into this complex, life-giving substance, and discusses the major gaps in what we understand about it.

Addiction is a disease -- but only one in nine addicted people in the US gets the care and treatment they need. Michael Botticelli is a former Director of National Drug Control Policy, and he's working to end this epidemic -- in part by treating people with addictions with kindness, compassion and fairness. In a personal, thoughtful talk, he encourages the millions of Americans in recovery today to make their voices heard. Watch »

Moshe Szyf is a pioneer in the field of epigenetics, the study of how living things reprogram their genome in response to things like stress and lack of food. His research suggests that biochemical signals passed from mothers to offspring can 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. "DNA is a dynamic movie in which our experiences are being written." Watch »

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. So Ashton Cofer and his science fair teammates developed a treatment to break down old Styrofoam into something useful. Check out their design, which won both the FIRST LEGO League Global Innovation Award and the Scientific American Innovator Award from Google Science Fair. Watch »

Quote of the Week

Nearly every family is affected by addiction. Yet, unfortunately, too often, it's not talked about openly and honestly. It's whispered about. It's met with derision and scorn. And those of us with an addiction, we hear those voices, and somehow we believe that we are less deserving of care and treatment.
    If you have cancer, you get treatment; if you have diabetes, you get treatment. But somehow people with addiction have to wait for treatment or often can't get when they need it. And left untreated, addiction has significant, dire consequences. We've been down that road before."

Michael Botticelli
Addiction is a disease. We should treat it like one

For many previous centuries (and for many reasons), creative storytelling has generally come from men, and from a male perspective. As director Jude Kelly points out, there's a more useful, more inclusive way to look at the world, and she calls on artists -- women and men -- to paint, draw, write about, film and imagine a gender-equal society.

John Koenig loves finding words that express our unarticulated feelings -- like "lachesism," the hunger for disaster, and "sonder," the realization that everyone else's lives are as complex and unknowable as our own. Here, he meditates on the meaning we assign to words and how these meanings latch onto us. Watch »
