We think laughter is a response to something funny.
A joke. A punchline. A light moment.

But listen closely to real conversations, and laughter shows up in places that are far more important than we realize - and often when nothing is funny at all.

Neuroscientist Sophie Scott CBE reveals what laughter really signals, how it works, and why it quietly shapes our relationships, our hierarchies, and our sense of belonging.

Sophie Scott is a professor at University College London and one of the world’s leading researchers on the science of laughter.

Elon Musk and Geoffrey Hinton warn of an AI-driven job apocalypse.

MIT’s David Autor, one of the world’s leading thinkers on how technology reshapes work, says the real danger lies somewhere else.

The biggest risk of AI isn’t mass unemployment - it’s whether human skills and expertise will still matter.

David explains how AI could expand middle-class opportunity by lowering barriers to high-value work, why past technologies created more new jobs than they destroyed, and what we need to get right to make this moment a hopeful one.

Jack Goldsmith, who once ran the Justice Department office that advises presidents on what they can and can’t legally do, takes on some of the hardest questions about the limits of the president’s power — from changing the government to the use of military force abroad, including the invasion of Venezuela.

Drawing on his experience inside the executive branch, he looks at why the limits on presidential power are more fragile than they appear, how precedent quietly expands executive authority, and what that means for the future of the presidency.
