What makes tattoos permanent? - Claudia Aguirre Further reading to recap what we learned. 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. Just How Small Is an Atom? - Jonathan Bergmann Whether we’re zooming in to the wavelength of a gamma ray or zooming out to the size of a galaxy, it can be difficult to wrap our heads around the big numbers we’re measuring—like nanometers (10-9meters) or gigameters (109). Take a look at these efforts to represent big numbers. What are the strengths of each? How would you represent a large number (like a gigameter)?

By tracking social media, it turns out, we can get much better at recognizing pandemics early. Solving epidemics has been the goal of physician Larry Brilliant’s career — and the basis for his 2006 TED Prize wish, which he updated this year in a talk at TED2013, above. His wish called for an “International System for Total Early Disease Detection,” or InSTEDD, a project with the mantra “Early detection, early response” — which included, among other features, tracking stories on the web to watch for patterns that indicate an epidemic is about to break out. After winning the TED Prize, Brilliant founded InSTEDD, a nongovernmental, multilingual, worldwide digital surveillance system that monitors the web, global news and social media for phrases and patterns that may signal a brand-new pandemic. In this update, Brilliant shares new data that shows … it’s working.
6 thinkers whose depressing ideas will make you feel better We are absurdly anxious about success, says popular philosopher Alain de Botton (TED Talk: Alain de Botton: A kinder, gentler philosophy of success). In his talk from 2009, he suggests that many of our modern values — like our sense of limitless possibility and upward growth — can actually lead us to stress harder about how well we’re doing. But the reverse can also be true, says de Botton. For TED, he’s put together this reading list of (mainly) pessimistic philosophers who have inspired his thinking about positivity. 1.

What does inequality do to our bodies? To our minds? What do a disease-fighting epidemiologist (retired) and an up-and-coming social psychologist have in common? They’re both fascinated by the unseen social problems hidden behind the word “inequality.” Beyond the lack of access to money and power — what does inequality do to us as human beings? Epidemiologist Richard Wilkinson (TED Talk: How economic inequality harms societies) spent his career studying chronic health problems — with the growing realization that most health issues are caused, or worsened, by poverty and inequality.
Remembering Robin Williams Robin Williams hijacks the TED2008 stage before the BBC World Debate. Photo: Andrew Heavens It’s 2008, moments before a BBC broadcast live from the stage at TED. But something’s gone wrong. The house lights are still up, the camera ops are looking at one another, official-looking folks are wandering at the stage apron muttering into headsets, and the panelists are sitting patiently onstage but looking, increasingly, baffled.

Clint Smith: The danger of silence Dr. Martin Luther King, Jr.,in a 1968 speech where he reflects upon the Civil Rights Movement,states, "In the end,we will remember not the words of our enemiesbut the silence of our friends." As a teacher, I've internalized this message.Every day, all around us,we see the consequences of silencemanifest themselves in the form of discrimination,violence, genocide and war.In the classroom, I challenge my studentsto explore the silences in their own livesthrough poetry.We work together to fill those spaces,to recognize them, to name them,to understand that they don't have to be sources of shame.In an effort to create a culture within my classroomwhere students feel safe sharing the intimaciesof their own silences,I have four core principles posted on the boardthat sits in the front of my class,which every student signs at the beginning of the year:read critically, write consciously,speak clearly, tell your truth.

What to do when your government collapses Last week, forty Syrians took the risk of leaving their homes and crossing the border into Turkey. Unlike many who cross, though, these Syrians planned to return. Their goal in Turkey: an intensive week-long workshop on how to rebuild their society. Leaders in their communities, they came from Aleppo, Damascus, Idlib, Homs, Hama and Dara’a to talk with a group of conflict-resolution experts in Istanbul, including me, about the toughest leadership challenge of our time — helping people not only survive day to day in the midst of civil war but create a vision for the future in the face of government collapse and unbelievable human suffering.

An original documentary about Earle’s life and work premieres today on Netflix. Watch it here. Below, four ocean infographic gifs from the film. What happened to the coral reefs?
