Viruses have a bad reputation -- but some of them could one day save your life, says biotech entrepreneur Alexander Belcredi. In this fascinating talk, he introduces us to phages, naturally-occurring viruses that hunt and kill harmful bacteria with deadly precision, and shows how these once-forgotten organisms could provide new hope against the growing threat of antibiotic-resistant superbugs.

Libraries have the power to create a better world; they connect communities, promote literacy and spark lifelong learners. But there's one thing that keeps people away: the fear of overdue book fines. In this thought-provoking talk, librarian Dawn Wacek makes the case that fines don't actually do what we think they do. What if your library just ... stopped asking for them altogether?

What exactly is civility, and what does it require? In a talk packed with historical insights, political theorist Teresa Bejan explains how civility has been used as both the foundation of tolerant societies and as a way for political partisans to silence and dismiss opposing views. Bejan suggests that we should instead try for "mere civility": the virtue of being able to disagree fundamentally with others without destroying the possibility of a common life tomorrow. (This talk contains mature language.)

Only if you are truly open to the possibility of being wrong can you ever learn, says researcher Alex Edmans. In an insightful talk, he explores how confirmation bias -- the tendency to only accept information that supports your personal beliefs -- can lead you astray on social media, in politics and beyond, and offers three practical tools for finding evidence you can actually trust. (Hint: appoint someone to be the devil's advocate in your life.)

When you look at Muslim scholar Dalia Mogahed, what do you see: A woman of faith? A scholar, a mom, a sister? Or an oppressed, brainwashed, potential terrorist? In this personal, powerful talk, Mogahed asks us, in this polarizing time, to fight negative perceptions of her faith in the media -- and to choose empathy over prejudice.

Who controls the internet? Increasingly, the answer is large corporations and governments -- a trend that's threatening digital privacy and access to information online, says web developer Tamas Kocsis. In this informative talk, Kocsis breaks down the different threats to internet freedom and shares his plan to build an alternative, decentralized network that returns power to everyday users.

"We are living in a world that is tantalizingly close to ensuring that no one need die of hunger or malaria or diarrhea," says economist Michael Green. To help spur progress, back in 2015 the United Nations drew up a set of 17 goals around important factors like health, education and equality. In this data-packed talk, Green shares his analysis on the steps each country has (or hasn't) made toward these Sustainable Development Goals -- and offers new ideas on what needs to change so we can achieve them.

Adults tend to think of kids as "future citizens" -- their ideas and opinions will matter someday, just not today. But kids make up a quarter of the population, so shouldn't they have a say in what the world they'll inherit will look like? Urban planner Mara Mintzer shares what happened when she and her team asked kids to help design a park in Boulder, Colorado -- and how it revealed an important blind spot in how we construct the built environment. "If we aren't including children in our planning, who else aren't we including?" Mintzer asks.

How does Hollywood choose what stories get told on-screen? Too often, it's groupthink informed by a narrow set of ideas about what sells at the box office. As a producer, Franklin Leonard saw too many great screenplays never get made because they didn't fit the mold.

Learn the origin story of some of your favorite films with this fascinating insider view of the movie business.

Özlem Cekic's email inbox has been full of hate mail since 2007, when she won a seat in the Danish Parliament -- becoming the first female Muslim to do so. At first she just deleted the emails, dismissing them as the work of fanatics, until one day a friend made an unexpected suggestion: to reach out to the hate mail writers and invite them to meet for coffee. Hundreds of "dialogue coffee" meetings later, Cekic shares how face-to-face conversation can be one of the most powerful forces to disarm hate -- and challenges us all to engage with people we disagree with.
