Artist eL Seed fuses the beauty of Arabic letters with the modern art of graffiti — an art form he calls calligraffiti. He paints colorful, undulating messages of hope and peace on buildings all over the world — from the favelas of Rio de Janeiro, to the bridges of Paris (the city where he was […]
Greg Gage is a reliable source of both shock and awe at TED. Onstage over the years, this TED Fellow has demonstrated his low-cost DIY teaching kits by amputating a cockroach leg to show how neurons fire, remote-controlling a cyborg cockroach to demonstrate how electrical stimulation guides behavior, and taking away an audience member’s free will to show how one person’s brain can control the arm movements of […]
Aomawa Shields is a woman of “contradictions.” An astronomer and astrobiologist, she searches for exoplanets where life might exist by using computer models to calculate the kind of atmosphere they’d need to support it. And she’s also a classically trained actor, who — through her organization Rising Stargirls — teaches astronomy to middle school girls of color using theater, writing and visual art to […]
We divide the world into civilians and soldiers. Rarely do we think about the human experience of war — the rhythm and flow of daily life on the front lines. Saeed Taji Farouky’s latest feature documentary, Tell Spring Not to Come This Year, follows a unit of the Afghan National Army during their first year of deployment without NATO […]
Like many kids, German-Moroccan paleontologist Nizar Ibrahim nursed a fascination for dinosaurs from a young age. The difference is, he grew up and actually found one. Ibrahim vividly remembers learning about Spinosaurus, a massive aquatic dinosaur whose only known bones were destroyed during World War II. As a kid, Ibrahim dreamed of finding new fossils of […]
For decades, the farmers of East Africa have battled the African whitefly, a tiny insect that infests the cassava crop. Cassava, also called manioc, arrowroot or tapioca, is an important food all over the world — more than half a billion people (yes, billion with a b) rely on cassava for their daily meals. For East African farmers, a whitefly infestation can completely destroy the year’s […]
Did you know that bacteria can be programmed as though they were computers? Bioengineer and artist Tal Danino is working out how to instruct bacteria to enter cancerous tumors — where it can detect and treat the disease noninvasively. And when Danino isn’t tinkering with bacteria’s healing potential, he makes artwork with it. With Danino’s TED talk posted just yesterday, he […]
In agricultural entrepreneur Trang Tran’s native Vietnam, farmers traditionally burn the straw and husks that remain after the rice harvest. This practice happens at least twice a year for two months at a time, releasing noxious smoke and greenhouse gases into the atmosphere. Tran’s solution: using rice straw to cultivate mushrooms. Her social enterprise Fargreen is […]
For the 50,000 people of the Faroe Islands, a self-governing country within the Kingdom of Denmark, hunting long-finned pilot whales — a dark gray species found in their waters — is a tradition that stretches back centuries. These whales are a food source, and hunting them is considered an important part of Faroese culture. Today, […]
Cockroaches. Moldy walls. Stolen deposits. Bad landlords happen to all of us, and it can be impossible to tell before moving into a property whether the experience will be a good one, especially in housing-short cities like New York, where landlords seem to hold the cards. But TED Fellow Yale Fox is looking to change that with RentCheck — […]

This week, Apple turned the iPhone into a medical research tool with the launch of ResearchKit. This open-source framework, described in the video above, lets a medical researcher set up a project to gather anonymous patient data on diseases like asthma, breast cancer and diabetes. Using their own smartphones, patients who join a project can […]
Award-winning photojournalist Boniface Mwangi captured the 2007-2008 post-election violence in Kenya unflinchingly through the lens of his camera. But the horrors he witnessed propelled him into a new career as an activist and artist. Here, Mwangi talks to the TED Blog about the events that led him to stand up against injustice, literally, rather than simply document it. Tell us about your experience on […]
Eco-entrepreneur Alasdair Harris is passionate about conserving marine biodiversity, and he’s doing it in unusual ways. While most marine conservationists focus on what’s in the water, Harris’ company Blue Ventures works with people in poverty-stricken coastal communities to engage them in rebuilding tropical fisheries and in the process of protecting both their ecosystems and livelihoods. The company’s approach: eco-tourism. We spoke […]
Alison Killing thinks a lot about death … and specifically, how its ubiquitous, hidden presence shapes our cities. In Death in Venice, her June 2014 exhibition on the topic, Killing mapped London’s death-associated architectural features — hospitals, cemeteries, crematoria, and so on — making visible the invisible mechanics of death and dying. She asks us to consider: What might […]
