Please join my mailing list here 👉 https://briankeating.com/yt to win a meteorite 💥 Nick Lane joins Brian Keating to argue that life is not information running on chemistry but energy in motion—showing how a single ancient metabolic “transformer” predates genes, powers mitochondria, shapes aging and cancer, constrains alien life, and reveals why today’s AI excitement echoes a solution biology discovered billions of years ago. 00:00 — Defining life vs. death; membrane potential as the boundary between living and dead 00:50 — The title “Transformer” and parallels between AI transformers and biochemical transformation 03:22 — Schrödinger’s What Is Life? and why defining life is intrinsically slippery 06:25 — Why the Krebs cycle sits at the center of metabolism 08:45 — The reverse Krebs cycle, CO₂ fixation, and links to cancer metabolism 11:35 — Mitochondrial membrane potential and the electrical field that powers life 15:00 — Reverse Krebs cycle vs. Calvin cycle and the evolution of carbon fixation 18:00 — Endosymbiosis: origin of mitochondria and chloroplasts 30:02 — Metabolism before genes; CO₂ + hydrogen and prebiotic chemistry 59:49 — Rapid-fire Q&A: RNA world critique and big open questions in origin-of-life research ------------------------------------------------------ ➡️ Follow Nick Lane 🌐 Website: https://www.nick-lane.net 📚 Transformer: The Deep Chemistry of Life and Death: https://nick-lane.net/books/transformer-the-deep-chemistry-of-life-and-death/ Join this channel to get access to perks like monthly Office Hours: https://www.youtube.com/channel/UCmXH_moPhfkqCk6S3b9RWuw/join 📚 Get my books: Think Like a Nobel Prize Winner, with productivity tips from 9 Nobel Prize winners: https://a.co/d/03ezQFu Focus Like a Nobel Prize Winner, with life-changing interviews with 9 Nobel Prizewinners: https://a.co/d/hi50U9U My tell-all cosmic memoir Losing the Nobel Prize: http://amzn.to/2sa5UpA The first-ever audiobook from Galileo: Dialogue Concerning the Two Chief World Systems: Ptolemaic and Copernican https://a.co/d/iZPi9Un Follow me to ask questions of my guests: 🏄‍♂️ Twitter: https://twitter.com/DrBrianKeating 🔔 Subscribe https://www.youtube.com/DrBrianKeating?sub_confirmation=1 📝 Join my mailing list; just click here http://briankeating.com/list ✍️ Detailed Blog posts here: https://briankeating.com/blog 🎙️ Listen on audio-only platforms: https://briankeating.com/podcast #universe #podcast #briankeating #intotheimpossible #science #astronomy #cosmology #cosmicmicrowavebackground #intotheimpossible #briankeating Learn more about your ad choices.

0:00.0	Tell me, Nick, what is life?
0:02.0	Ah, well, I can't tell you.
0:04.0	If you get an answer from someone, it'll be a bad answer.
0:08.0	Seems like it might be easier to answer the question, what is death?
0:12.0	Death is really easily. You lose your membrane potential permanently. That's it.
0:16.0	We are burning rocket fuel.
0:18.0	Nick Lane, thank you for joining us all the way from London, I presume.
0:22.9	I am in London, yes.
0:24.8	Very good. I've been wanting to do this interview for years now.
0:27.9	This is a real treat for me and my audience.
0:30.3	And I want to start with something that, you know, I came to maybe you were presciently
0:35.7	aware of this before you wrote the book or when you were writing
0:38.5	the book as you often are that the letter t in gpt would take over the world and it does stand for
0:44.9	transformer in chat gpt generative pre-trained transformer nick were you ahead of the curve
0:50.5	when you wrote this book in 2020 2021 when you were writing it i'd love to say love to say I was, but I wasn't really. It became very clear when I was writing it.
0:57.8	So, yes, I was pleased with the title. The title goes back actually some years before that.
1:03.2	And at that time, it was not so much common usage at all.
1:08.2	Well, we'll talk about the title of the book, the cover design of the book, but I do want
1:12.3	to talk about the, at least the transformer aspect of it.
1:16.6	In the world of AI, which is, you know, kind of eating the world, transformer, you know,
1:23.3	is this mechanism by which information flows through a system doesn't get absorbed or consumed.
1:31.3	It kind of acts like a catalyst in some way.
