Teachers emotionally support our kids -- but who's supporting teachers?

A historical musical that examines black identity in the 1901 World's Fair | Amma Y. Ghartey-Tagoe Kootin
In this lively talk and performance, artist and TED Fellow Amma Y. Ghartey-Tagoe Kootin offers a sneak peek of her forthcoming musical "At Buffalo." Drawing on archival material from the 1901 Pan-American Exhibition, a world's fair held in Buffalo, New York, the show examines conflicting representations of black identity exhibited at the fair -- highlighting unsettlingly familiar parallels between American society at the turn of the century and today, and asking: Are we all still part of the show?
Taking inspiration from nature, architect Ma Yansong designs breathtaking buildings that break free from the boxy symmetry of so many modern cities.

Social media has become our new home. Can we build it better?

Imagine living with no significant human contact for years, even decades, in a cell the size of a small bathroom. This is the reality for those in long-term solitary confinement, a form of imprisonment regularly imposed in US prisons. In this eye-opening talk, civil rights lawyer Laura Rovner takes us to ADX, the US federal government's only supermax prison, and describes the dehumanizing effects of long-term solitude on the mind, personality and sense of self. What emerges is an urgent case for abolishing solitary confinement -- and evidence for how our tax dollars, public safety and values are implicated in it. "Prisons are administered in our name and on our behalf," she says. "We have an obligation to bear witness."

The cells in your body are like computer software: they're "programmed" to carry out specific functions at specific times. If we can better understand this process, we could unlock the ability to reprogram cells ourselves, says computational biologist Sara-Jane Dunn. In a talk from the cutting-edge of science, she explains how her team is studying embryonic stem cells to gain a new understanding of the biological programs that power life -- and develop "living software" that could transform medicine, agriculture and energy.
Stories help you make sense of your life -- but when these narratives are incomplete or misleading, they can keep you stuck instead of providing clarity.
