Harvard professor Arthur Brooks explains why boredom is useful rather than something to avoid. He describes how a wandering mind engages the brain's default mode network, which supports creativity and curiosity, and suggests it may protect against depression.

Andrew Huberman's long Huberman Lab episode is a masterclass on dopamine. It covers the neural circuits, peaks and baselines, dopamine depletion, and 14 tools for motivation, focus and avoiding addiction.

Andrew Huberman's podcast episode on what makes us sleepy, helps us sleep soundly and keeps us alert. It lays out the science and a set of behavioral tools such as light timing.

Adam Neely explains what perfect (absolute) pitch is, how it differs from relative and quasi-absolute pitch, and why he would not want it. He covers its drawbacks, including drift with age.

Vsauce explores whether people in past decades really looked older than people of the same age today, or whether photographic and cultural factors make them seem so. It draws on old photos, yearbooks and perception research.

Lex Fridman talks with Tufts biologist Michael Levin about bioelectricity, embryogenesis, xenobots and how cells collectively pursue goals. They range into cognition, evolution and the possibility of aliens.

Lex Fridman has a three-hour conversation with Joscha Bach about artificial consciousness, the workings of the mind, intelligence and the possibly simulated nature of reality.

Curt Jaimungal interviews biologist Michael Levin of Tufts about consciousness, bioelectricity, emergence, and cancer research. The conversation challenges reductionist views of life.
