A recording from my enthralling conversation with Prof Matthew Cobb about the life and science contributions of Francis Crick, regarded as one of the most influential biologists of all times, along with Darwin and Mendel. As you’ll see, there’s so much more to Crick’s story than cracking DNA’s double helix structure in a matter of weeks with James Watson. Matthew Cobb, Emeritus Professor of the University of Manchester, has written several award-winning books on life science, but I think this is his most important one to date, deeply researched and a thrilling account of Crick’s life, clearing up, as best as one can, many questions, and presenting some surprises. The transcript is available (A.I. generated) by clicking at the top right. A few things we discussed —Crick’s reaction to James Watson’s book Crick contrasted his own approach to science writing with Watson’s memoir: “The difference between my lecture and your book is that my lecture had a lot more intellectual content and nothing like so much gossip. (...) Your book on the other hand, is mainly gossip and I think it a pity in this way that there is so much of it that it obscures some of the important conclusions which can be drawn of what we did at the time”. —The Peyote Poem, by Michael McClure (part 1) that had a big influence on Crick —Crick’s 1994 neuroscience book “The Astonishing Hypothesis” “You, your joys and your sorrows, your memories and your ambitions, your sense of personal identity and free Weill, are in fact no more than the behavior of a vast assembly of nerve cells and their associated molecules.”—Crick The book has been reviewed at Science, Nature, The Economist and many other journals. Here is a gift link to The Economist It has deservedly been named a best book of 2025 by The Guardian, The Economist, and many other media.

Michael Lewis is one of the best storytellers of our era. You know and likely have read his books Moneyball, The Big Short, The Blind Side, Flash Boys, Liar’s Poker, and The Undoing Project, to name a few. He has long been one of my favorite authors. This was the first interview that Michael did on his new book, BLOCKERS, published on October 6th, streamed live on Substack Sept 29th. It’s his 21st book and 4 of the last 5 have been about the US government: The Fifth Risk (2019), Premonition (2021), and Who Is Government? (2025). His ability to talk with the silent civil servant heroes of multiple government agencies (the Blockers), members of the DOGE destruction team, and much more from the current US government administration.
In recent weeks the results (announced by press release) of 2 major placebo-controlled randomized trials—ZEUS, testing an interleukin-6 (IL-6) blocker vs inflammation, and HORIZON, testing a drug to lower Lp(a), indicated failure to achieve their primary endpoint. Are we maxxed out for new treatments vs heart disease, as this article in the WSJ (←gift link) today asserts? “Cardiovascular drug development is starting to look a bit like the modern oil industry. The easy wells have been tapped. What’s left is in deep water: expensive, technically perilous and less likely to strike oil.”
This podcast is meant to complement my recent Ground Truths post Why Our Memory Slips After Age 50 which has all the relevant links to the 2 papers, key graphics, and other related publications. If you haven’t had a chance to read that, it would be helpful to spend a few minutes to do so before listening to this podcast. Links to the 2 papers for those who don’t want to look back Zemke et al in Science https://www.science.org/doi/10.1126/science.adt8307 Belk et al in Nature https://www.nature.com/articles/s41586-026-10939-0
Deb Cohen is an award winning investigative journalist and correspondent who trained as a physician and has worked with the BBC and BMJ. She just published BAD INFLUENCE, a book which takes us deep into the wellness-industrial complex—the confluence of the supplement, testing, tech, and pharma industries, and how they sell health anxiety to healthy people.
Sarah Urbut is a physician-scientist at Harvard Medical School and the Massachusetts General Research Institute. She and her colleagues published a landmark paper in Nature on patient health journeys for 3 different cohorts—the Mass General Brigham patients, the UK Biobank, and the All of Us research program—with a cumulative 683,000 individuals, 348 diseases, and up to 52 years of follow-up. Integrating electronic medical records and polygenic risk scores (N=36). An AI model was developed and validated called ALADYNOULLI, with each individual represented latent disease signatures (N=21), mathematically and biologically driven. An example of a patient’s dynamic life journey (health arc) is provided in the Figure below (adapted from the paper, made with NotebookLM). The longitudinal story for each individual is key here. Using a Gaussian process, the risk continually shifts like a GPS navigation when you make a wrong turn and you are re-routed. Considerable effort was dedicated to addressing selection bias with inverse probability weighting.
