Why I’m teaching prisoners to code

I had never been in a prison before, especially one with as ominous a reputation as San Quentin. When I arrived, I was escorted through a series of gates that eventually led to the main courtyard. On my left was the adjustment center that houses death-row inmates, some of the notorious criminals in California. On my right was the Catholic Chapel, surrounded by a well-manicured garden. I was, as they say at San Quentin, at the gate between heaven and hell. As the sun was setting, I was led down a paved road, past the guard towers into the lower yard where hundreds of men in blue were exercising, playing chess or just milling around. Frankly, at that point, I was questioning my decision to come there. Linda Liukas: A delightful way to teach kids about computers.

Eye phone: How a TED Fellow’s app could help restore sight to millions

Photo: Ryan Lash/TED Around 39 million people in the world are affected by blindness — 80% of which could be avoided if people had timely access to diagnosis and proper treatment. The problem is that in many developing countries, most eye care providers are in cities, while the majority of patients live in hard-to-reach rural areas. To bridge this gap, London-based opthalmologist Andrew Bastawrous created Peek — an app and adapter that turn a smartphone into a comprehensive, easy-to-use, accurate eye-exam tool. Peek makes eye tests affordable and easy to administer, bypassing the need for expensive, fragile equipment. Bastawrous developed and extensively road-tested Peek during a research expedition in Kenya, and has now launched an Indiegogo campaign to set up manufacturing process for the Peek Retina adapter, which allows health workers to peer into the eye and capture images for diagnosis.

Announcing our TED Prize 2015 winner: Dave Isay of StoryCorps

This is why, for the 10th anniversary of the TED Prize in 2015, we are thrilled to award the million-dollar prize to Dave Isay, the founder of StoryCorps.

Death and the missing piece of medical school

I was given a dry, leathery corpse to dissect in my first term — but that was solely a way to learn about human anatomy. Our textbooks had almost nothing on aging or frailty or dying. Frans de Waal: Moral behavior in animals. 10 places where anyone can learn to code.

Teens, tweens and kids are often referred to as “digital natives.”

10 places where anyone can learn to code

Having grown up with the Internet, smartphones and tablets, they’re often extraordinarily adept at interacting with digital technology. But Mitch Resnick, who spoke at TEDxBeaconStreet, is skeptical of this descriptor. Sure, young people can text and chat and play games, he says, “but that doesn’t really make you fluent.” Mitch Resnick: Let's teach kids to code Fluency, Resnick proposes in this TED Talk, comes not through interacting with new technologies, but through creating them. The former is like reading, while the latter is like writing. Candy Chang: Before I die I want to... How should we talk about mental health?

Mental health suffers from a major image problem.

How should we talk about mental health?

One in every four people experiences mental health issues — yet more than 40 percent of countries worldwide have no mental health policy. Across the board it seems like we have no idea how to talk about it respectfully and responsibly. Stigma and discrimination are the two biggest obstacles to a productive public dialogue about mental health; indeed, the problem seems to be largely one of communication. How to trust intelligently. “The aim [in society] is to have more trust.

How to trust intelligently

Well frankly, I think that’s a stupid aim,” says Baroness Onora O’Neill in today’s talk, What we don’t understand about trust. She argues that the aim to build more trust is a cliché, and instead what we need is more trustworthiness. Below O’Neill gives a more nuanced picture of how to trust more intelligently, based on her criteria for trustworthiness. Faire confiance a priori: Frédéric Lippi à TEDxLaRochelle.

Scientist Sylvia Earle (TED Talk: My wish: Protect our oceans) has spent the past five decades exploring the seas. During that time, she’s witnessed a steep decline in ocean wildlife numbers — and a sharp incline in the number of ocean deadzones and oil drilling sites.

Urban legend has it that tattooed patients undergoing Magnetic Resonance Imaging (MRI) have experienced the ink being ripped from their skin – Is it true? Even though the presence of metal is common in pigments, there are no documented reports of tattoos being “ripped out” during a routine MRI.

But some people do exhibit swelling, itching or burning after getting scanned. There are also reports of pigments causing problems with the MRI results, perhaps because of the metals in the inks (FDA, 2011). While there is no reason to avoid getting an MRI scan, the radiologist or technician should know so appropriate precautions can be taken.
