A one-hour documentary on XBAND, the 1994 modem network for the Super Nintendo and Sega Genesis. It covers matchmaking, chat, email, leaderboards and how games were patched at runtime to cope with lag.

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.

A Capella Science parody of Despacito that sings through evolutionary developmental biology, explaining how a single cell becomes a body, including body-axis genes and dormant snake leg DNA. It runs about four minutes.

Stated Clearly explains the RNA world hypothesis, which resolves the chicken-or-egg problem of genes versus enzymes by proposing that RNA once did both jobs. It outlines how evolution could begin with RNA chains alone.

Michael Levin's keynote at the ALife 2020 conference, 'Robot Cancer', on how bioelectric signaling in embryogenesis and regeneration informs unconventional computing, cognition and the 'software of life'. He argues biology offers lessons for building adaptive machines.

William Li presents anti-angiogenesis, the idea of cutting off the blood supply that feeds tumors, and argues that certain foods can help do this. It is a TED-Ed version of his TED talk.

A one-minute demo comparing RetroArch shaders on the Sonic the Hedgehog waterfall, where Sega Genesis dithering creates a transparency effect. It shows how different shaders emulate the CRT look.

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.

Michael Levin's NeurIPS 2018 talk on bioelectric computation outside the nervous system, showing how cell electrical networks shape development and regeneration. It covers morphological information processing in living tissue.

Biologist Michael Levin explains the bioelectric layer that coordinates cells to build organs and bodies, showing footage of two-headed worms and introducing xenobots. He discusses implications for medicine and the nature of life.

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.

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.

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.

Developmental and synthetic biologist Michael Levin speaks at a Harvard Extension student event on bioelectricity, body intelligence and regenerative medicine. He discusses how cell electrical networks guide growth and form.

A short Coding Secrets episode explaining why hitting a Sonic 3D cartridge triggers a hidden level select. The cause was a custom crash handler that redirected CPU error interrupts to the level select screen.

The opening lecture of Robert Sapolsky's Stanford course on Human Behavioral Biology, explaining the course premise and how to avoid categorical thinking. It starts a roughly 25-lecture series on how biology, genes, hormones and environment shape behavior.

A PBS Space Time episode introducing de Broglie-Bohm pilot wave theory, an interpretation of quantum mechanics that avoids much of the strangeness of the mainstream views. It is aimed at curious lay viewers.

A Plogue developer shows the custom electronic test rigs built to measure the Sega Mega Drive/Genesis sound chip (YM2612) for the chipsynth MD emulation. It covers the years of testing and reverse engineering needed to reproduce the chip's quirks accurately.

Steve Hsu's 2011 Google Tech Talk reviews psychometric measurement of intelligence and the heritability of adult IQ, then discusses genome-wide association studies seeking the genes behind cognitive ability.
