The surprising science of alpha males | Frans de Waal
In this fascinating look at the "alpha male," primatologist Frans de Waal explores the privileges and costs of power while drawing surprising parallels between how humans and primates choose their leaders. His research reveals some of the unexpected capacities of alpha males -- generosity, empathy, even peacekeeping -- and sheds light on the power struggles of human politicians. "Someone who is big and strong and intimidates and insults everyone is not necessarily an alpha male," de Waal says.
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."
How I'm bringing queer pride to my rural village | Katlego Kolanyane-Kesupile
In a poetic, personal talk, TED Fellow Katlego Kolanyane-Kesupile examines the connection between her modern queer lifestyle and her childhood upbringing in a rural village in Botswana. "In a time where being brown, queer, African and seen as worthy of space means being everything but rural, I fear that we're erasing the very struggles that got us to where we are now," she says. "Indigenizing my queerness means bridging the many exceptional parts of myself."
The incredible potential of flexible, soft robots | Giada Gerboni
Robots are designed for speed and precision -- but their rigidity has often limited how they're used. In this illuminating talk, biomedical engineer Giada Gerboni shares the latest developments in "soft robotics," an emerging field that aims to create nimble machines that imitate nature, like a robotic octopus. Learn more about how these flexible structures could play a critical role in surgery, medicine and our daily lives.
How to get empowered, not overpowered, by AI | Max Tegmark
Many artificial intelligence researchers expect AI to outsmart humans at all tasks and jobs within decades, enabling a future where we're restricted only by the laws of physics, not the limits of our intelligence. MIT physicist and AI researcher Max Tegmark separates the real opportunities and threats from the myths, describing the concrete steps we should take today to ensure that AI ends up being the best -- rather than worst -- thing to ever happen to humanity.
