Jack Szostak's lecture covers how cellular life could have arisen from chemistry on the early Earth, starting from the odds of life elsewhere in the galaxy. It is part of a series on protocells and the RNA world.

A short Harvard Online animated lesson on how the mitochondrial electron transport chain works. It shows proton pumping and the machinery that drives ATP synthesis.

A lecture by Prof. Thomas Seyfried arguing that cancer is primarily a metabolic disease rather than a genetic one. It covers the Warburg effect, mitochondrial damage and implications for therapies.

A Ninja Nerd whiteboard lecture on the Moderna, Pfizer/BioNTech and AstraZeneca COVID-19 vaccines. It covers how each works, the preclinical and phase I-III trial process, and Operation Warp Speed.

Michael Levin presents his lab's work on how cellular collectives use bioelectric networks to make anatomical decisions. Topics include pattern memories, regeneration and synthetic living organisms.

Ron Vale of UCSF and HHMI gives an introductory lecture on kinesin, dynein and myosin motor proteins. He covers their roles in cells and how they turn ATP hydrolysis into directed motion and force.

Biochemist Nick Lane gives a Royal Institution lecture arguing that the Krebs cycle is central to what makes cells alive, not just genetic information. He draws on the themes of his book Transformer to link metabolism to the origin of life, death, and aging.

David Shaw of D. E. Shaw Research presents Anton, a special-purpose machine that speeds up biomolecular simulations about a hundred-fold. The lecture covers molecular dynamics and how simulation helps understand how drugs bind.

Robert Sapolsky's Stanford lecture on chaos and reductionism, which he calls one of the hardest of the course. It examines the limits of breaking systems into parts to understand them and introduces chaotic systems.

Nick Lane's Royal Institution lecture on the origin of life and why it is the way it is. It draws on his book The Vital Question and the alkaline hydrothermal vent theory of abiogenesis.

Synthetic organic chemist James Tour gives a lecture arguing that origin-of-life research is far from explaining how life began. The talk was published by the Discovery Institute and drew sharp criticism.
