Did the global response to 9/11 make us safer? | Benedetta Berti

If we want sustainable, long-term security to be the norm in the world, it’s time to radically rethink how we can achieve it, says TED Fellow and conflict researcher Benedetta Berti. In an eye-opening talk, Berti explains how building a safer world has a lot less to do with crushing enemies on the battlefield and a lot more to do with protecting civilians — no matter where they’re from or where they live.

A new way to fund health care for the most vulnerable | Andrew Bastawrous

In 2011, eye surgeon and TED Fellow Andrew Bastawrous developed a smartphone app that brings quality eye care to remote communities, helping people avoid losing their sight to curable or preventable conditions. Along the way, he noticed a problem: strict funding regulations meant that he could only operate on people with specific diseases, leaving many others without resources for treatment. In this passionate talk, Bastawrous calls for a new health care funding model that’s flexible and ambitious — to deliver better health to everyone, whatever their needs are.

How AI is making it easier to diagnose disease | Pratik Shah

Today’s AI algorithms require tens of thousands of expensive medical images to detect a patient’s disease. What if we could drastically reduce the amount of data needed to train an AI, making diagnoses low-cost and more effective? TED Fellow Pratik Shah is working on a clever system to do just that. Using an unorthodox AI approach, Shah has developed a technology that requires as few as 50 images to develop a working algorithm — and can even use photos taken on doctors’ cell phones to provide a diagnosis. Learn more about how this new way to analyze medical information could lead to earlier detection of life-threatening illnesses and bring AI-assisted diagnosis to more health care settings worldwide.

Why doctors are offering free tax prep in their waiting rooms | Lucy Marcil

More than 90 percent of children in the US see a doctor at least once a year, which means countless hours spent in waiting rooms for parents. What if those hours could be used for something productive — like saving money? Through her organization StreetCred, pediatrician and TED Fellow Lucy Marcil is offering free tax prep to parents right in the waiting room, reimagining what a doctor’s visit can look like and helping to lift families out of poverty. Learn more about how free tax prep and guidance could be the best poverty prescription we have in the US.

What the Russian Revolution would have looked like on social media | Mikhail Zygar

History is written by the victors, as the saying goes — but what would it look like if it was written by everyone? Journalist and TED Fellow Mikhail Zygar is on a mission to show us with Project1917, a “social network for dead people” that posts the real diaries and letters of more than 3,000 people who lived during the Russian Revolution. By showing the daily thoughts of the likes of Lenin, Trotsky and many less celebrated figures, the project sheds new light on history as it once was — and as it could have been. Learn more about this digital retelling of the past as well as Zygar’s latest project about the transformative year of 1968.

The symbols of systemic racism — and how to take away their power | Paul Rucker

Multidisciplinary artist and TED Fellow Paul Rucker is unstitching the legacy of systemic racism in the United States. A collector of artifacts connected to the history of slavery — from branding irons and shackles to postcards depicting lynchings — Rucker couldn’t find an undamaged Ku Klux Klan robe for his collection, so he began making his own. The result: striking garments in non-traditional fabrics like kente cloth, camouflage and silk that confront the normalization of systemic racism in the US. “If we as a people collectively look at these objects and realize that they are part of our history, we can find a way to where they have no more power over us,” Rucker says. (This talk contains graphic images.)

Four billion years of evolution in six minutes | Prosanta Chakrabarty

Did humans evolve from monkeys or from fish? In this enlightening talk, ichthyologist and TED Fellow Prosanta Chakrabarty dispels some hardwired myths about evolution, encouraging us to remember that we’re a small part of a complex, four-billion-year process — and not the end of the line. “We’re not the goal of evolution,” Chakrabarty says. “Think of us all as young leaves on this ancient and gigantic tree of life — connected by invisible branches not just to each other, but to our extinct relatives and our evolutionary ancestors.”
