Are children poor liars? Do you think you can easily detect their lies? Developmental researcher Kang Lee studies what happens physiologically to children when they lie. They do it a lot, starting as young as two years old, and they're actually really good at it. Lee explains why we should celebrate when kids start to lie (really!) and presents a new lie-detection technology that could someday reveal our hidden emotions.
What happens in your brain when you hear a good story? In the lab of neuroscientist Uri Hasson, experiments reveal that even across different languages, our brains show similar activity, or become "aligned," when we hear the same idea or story. This amazing neural mechanism allows us to transmit brain patterns, sharing memories and knowledge. "We can communicate because we have a common code that presents meaning," Hasson says. Watch »

A technique called CRISPR allows scientists to easily change a sequence of DNA -- and even guarantee that the edited genetic trait is inherited by future generations. This opens up the possibility of altering an entire species forever; imagine editing a disease-resistant mosquito so it no longer transmits Zika. How will this new power affect humanity? What are we going to use it to change? Are we gods now? Join journalist Jennifer Kahn as she ponders these questions. Watch »
What if we could find cancerous tumors years before they can harm us -- without expensive screening facilities or even steady electricity? Physician and bioengineer Sangeeta Bhatia leads a multidisciplinary lab that searches for novel ways to understand, diagnose and treat human disease. Her target: the two-thirds of deaths due to cancer that she believes are fully preventable. With remarkable clarity, she breaks down complex nanoparticle science and shares her dream for a radical new cancer test that could save millions of lives. Watch »
Imagine that you invented a device that can record my memories, my dreams, my ideas, and transmit them to your brain. That would be a game-changing technology, right? But in fact, we already possess this device, and it's called storytelling."
