Each year, the world loses enough food to feed half a billion people to fungi, the most destructive pathogens of plants. Mycologist and TED Fellow Mennat El Ghalid explains how a breakthrough in our understanding of the molecular signals fungi use to attack plants could disrupt this interaction -- and save our crops.

As quantum computing matures, it's going to bring unimaginable increases in computational power along with it -- and the systems we use to protect our data (and our democratic processes) will become even more vulnerable. But there's still time to plan against the impending data apocalypse, says encryption expert Vikram Sharma. Learn more about how he's fighting quantum with quantum: designing security devices and programs that use the power of quantum physics to defend against the most sophisticated attacks.

What if we incentivized doctors to keep us healthy instead of paying them only when we're already sick? Matthias Müllenbeck explains how this radical shift from a sick care system to a true health care system could save us from unnecessary costs and risky procedures -- and keep us healthier for longer.

What if you could tell your co-workers what you really think of them? At the world's most successful hedge fund, everyone is rated and ranked constantly -- in front of everyone. They've figured out how to embrace negative feedback, and they swear it's essential to their success. Adam Grant shows how you can learn to take criticism well -- and get better at dishing it out. This episode is brought to you by Bonobos, Accenture, JPMorgan Chase & Co., and Warby Parker. (Audio only)

The United States locks up more people than any other country in the world, says documentarian Eve Abrams, and somewhere between one and four percent of those in prison are likely innocent. That's 87,000 brothers, sisters, mothers and fathers -- predominantly African American -- unnecessarily separated from their families, their lives and dreams put on hold. Using audio from her interviews with incarcerated people and their families, Abrams shares touching stories of those impacted by mass incarceration and calls on us all to take a stand and ensure that the justice system works for everyone.

"Where do great ideas come from?" Starting with this question in mind, Vittorio Loreto takes us on a journey to explore a possible mathematical scheme that explains the birth of the new. Learn more about the "adjacent possible" -- the crossroads of what's actual and what's possible -- and how studying the math that drives it could explain how we create new ideas.

In 2014, as a newly trained physician, Soka Moses took on one of the toughest jobs in the world: treating highly contagious patients at the height of Liberia's Ebola outbreak. In this intense, emotional talk, he details what he saw on the frontlines of the crisis -- and reveals the challenges and stigma that thousands of survivors still face.

We use rituals to mark the early stages of our lives, like birthdays and graduations -- but what about our later years? In this meditative talk about looking both backward and forward, Bob Stein proposes a new tradition of giving away your things (and sharing the stories behind them) as you get older, to reflect on your life so far and open the door to whatever comes next.

Liz Ogbu is an architect who works on spatial justice: the idea that justice has a geography and that the equitable distribution of resources and services is a human right. In San Francisco, she's questioning the all too familiar story of gentrification: that poor people will be pushed out by development and progress. "Why is it that we treat culture erasure and economic displacement as inevitable?" she asks, calling on developers, architects and policymakers to instead "make a commitment to build people's capacity to stay in their homes, to stay in their communities, to stay where they feel whole."

Director and playwright Adong Judith creates provocative art that sparks dialogue on issues from LGBTQ rights to war crimes. In this quick but powerful talk, the TED Fellow details her work -- including the play "Silent Voices," which brought victims of the Northern Ugandan war against Joseph Kony's rebel group together with political, religious and cultural leaders for transformative talks. "Listening to one another will not magically solve all problems," Judith says. "But it will give a chance to create avenues to start to work together to solve many of humanity's problems."

Something strange and deadly is happening inside the brains of top athletes -- a degenerative condition, possibly linked to concussions, that causes dementia, psychosis and far-too-early death. It's called chronic traumatic encephalopathy, or CTE, and it's the medical mystery that Chris Nowinski wants to solve by analyzing brains after death. It's also why, when Nowinski meets a pro athlete, his first question is: "Can I have your brain?" Hear more from this ground-breaking effort to protect athletes' brains -- and yours, too.

We're all against hate, right? We agree it's a problem -- their problem, not our problem, that is. But as Sally Kohn discovered, we all hate -- some of us in subtle ways, others in obvious ones. As she confronts a hard story from her own life, she shares ideas on how we can recognize, challenge and heal from hatred in our institutions and in ourselves.

The arts bring meaning to our lives and spirit to our culture -- so why do we expect artists to struggle to make a living? Hadi Eldebek is working to create a society where artists are valued through an online platform that matches artists with grants and funding opportunities -- so they can focus on their craft instead of their side hustle.

"Will machines replace humans?" This question is on the mind of anyone with a job to lose. Daniel Susskind confronts this question and three misconceptions we have about our automated future, suggesting we ask something else: How will we distribute wealth in a world when there will be less -- or even no -- work?

According to the US Department of Education, more than 85 percent of black fourth-grade boys aren't proficient in reading. What kind of reading experiences should we be creating to ensure that all children read well? In a talk that will make you rethink how we teach, educator and author Alvin Irby explains the reading challenges that many black children face -- and tells us what culturally competent educators do to help all children identify as readers.
