What if animals like dogs, ferrets, mice and raccoons could help sniff out the next pandemic? Exploring the science of smell, neurobiologist Glen J. Golden delves into the development of a "mechanical nose" that could detect diseases by identifying specific odor profiles. Until that technology is fully developed, he explains how we can train humanity's furry allies to identify illnesses — and help stop the spread in its tracks.

AI has the potential to impact the way humans interact with the world — and each other. Social psychologist Brian S. Lowery and AI technologist Kylan Gibbs dive into the ramifications of emerging technologies on people's mental health and social dynamics. Hear why Gibbs thinks, counterintuitively, the more we use AI, the less real it will feel — and how Lowery suggests we fulfill our intrinsic need for connection amid dizzying technological advances.

Why are some people really funny and others ... not so much? Comedian Chris Duffy shows how you can sharpen your sense of humor and start laughing every day — by seeing the world like a kid.

When playwright David Finnigan staged a play titled "Kill Climate Deniers" in 2014, he knew it'd get a strong reaction. What he wasn't prepared for was the idea that the blowback might actually cause him to rethink his own response to climate change. But as he shares in this delightfully engaging talk, his conversations with skeptics of all stripes ultimately taught him a fresh and fascinating lesson about how we can all think about — and act upon — the climate crisis.

What does it actually take to make meaningful change? Conservationist Kristine McDivitt Tompkins and playwright and theater director Amir Nizar Zuabi reflect on the deep connection between human suffering and environmental degradation and the community-building power of art to raise awareness.
