Irina Kareva translates biology into mathematics and vice versa. She writes mathematical models that describe the dynamics of cancer, with the goal of developing new drugs that target tumors. "The power and beauty of mathematical modeling lies in the fact that it makes you formalize, in a very rigorous way, what we think we know," Kareva says. "It can help guide us to where we should keep looking, and where there may be a dead end." It all comes down to asking the right question and translating it to the right equation, and back.

How can we make AI that people actually want to interact with? Raphael Arar suggests we start by making art. He shares interactive projects that help AI explore complex ideas like nostalgia, intuition and conversation -- all working towards the goal of making our future technology just as much human as it is artificial.

Ndidi Nwuneli has advice for Africans who believe in God -- and Africans who don't. To the religious, she advises against using God to outsource responsibility for what happens in their lives. To the non-religious, she asks that they keep an open mind and work with faith-based organizations, especially on issues like health care and education. "There's so much potential that can be realized when we walk across the divide of faith and, hand in hand, try to solve many of our problems," Nwuneli says.

In the US, your taxes fund academic research at public universities. Why then do you need to pay expensive, for-profit journals for the results of that research? Erica Stone advocates for a new, open-access relationship between the public and scholars, making the case that academics should publish in more accessible media. "A functioning democracy requires that the public be well-educated and well-informed," Stone says. "Instead of research happening behind paywalls and bureaucracy, wouldn't it be better if it was unfolding right in front of us?"

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.

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 the 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.
