Denis Noble & Michael Levin | What Biology needs to Advance Longevity

Denis Noble and Michael Levin - two great minds in biology come together on Live Longer World. Denis Noble is a renowned biologist and pioneer in systems biology, known for his groundbreaking work on the electrical activity of the heart and his influential contributions to the understanding of biological systems. Denis is an advocate for taking a systems integrative approach to biology, as opposed to the reductionist gene-centric view that has dominated the field due to Neo-Darwinism. The gene-centric view has failed us in advancing progress on many diseases, and we need to now take a systems based approach focused on functional networks within biological systems. Michael Levin is an American developmental and synthetic biologist at Tufts University, where he is the Vannevar Bush Distinguished Professor. His research is focused on bioelectricity and he is my co-host for this podcast. We discuss: - DNA is not the blueprint of life - Why biology’s reductionist approach is flawed - The errors in Neo-Darwinism - Epigenetic inheritance - How to advance the cure of diseases Episode Show Notes: https://livelongerworld.com/p/dnoble Find me: https://x.com/aasthajs TIMESTAMPS: 0:00 Denis as Mike Levin’s hero 0:10 Denis’s journey to systems biology; cell voltage is a global property of the cell 3:45 Advice to young researchers pursuing systems biology 7:00 “Absolutely everything is wrong with Neo-Darwinism” 14:10 Epigenetic inheritance 19:12 Genetic vs. other information used by organisms 23:48 Biology textbooks have to expand beyond DNA in 50 years 25:03 Epigenetic processes are ubiquitous 28:58 If not DNA, what is the blueprint of life 36:15 Rewriting biology textbooks is fundamental 39:57 “A lot of time has been wasted” (in biology) 46:52 Darwin on the “Origin of Species” 55:38 “Unfortunate that Philosophy and science have diverged” 1:00:31 Importance of Functional networks; DNA does not predict disease AASTHA, LIVE LONGER WORLD: Twitter: https://x.com/aasthajs Newsletter: https://livelongerworld.com/ Instagram: https://www.instagram.com/aasthajs/ LINKS: Michael Levin: https://twitter.com/drmichaellevin Denis's book Dance to the Tune of Life: https://a.co/d/3hvh5JW Episode Show Notes: https://livelongerworld.com/p/dnoble Michael Levin on Bioelectric Signals for Longevity: https://youtu.be/XboYI_wxDr8?si=WrQ_iI8ABbG6eibm

This interview is part of my series with Dr. Michael Levin where we interview significant people in the history of developmental bioelectricity. Dr. Mustafa Djamgoz was one of the first people to study the role of ion channels and bioelectricity in cancer, which he initially documented in a 1995 paper. His research showed that there was an uptake in voltage-gated sodium channels in all types of cancer metastasis, except prostate cancer, highlighting the significant role of studying ion channels in cancer. Simply put, the spread of cancer cells is linked to increased activity in sodium ion channels, which regulate electrical currents in our cells.

Dr. Alfonso Martinez Arias is a development biologist and the author of the book The Master Builder: How the New Science of the Cell Is Rewriting the Story of Life. He also co-authored the biology textbook Principles of Development, which was awarded the Royal Society of Biology book prize. Episode Show Notes: https://livelongerworld.com/p/aarias OVERVIEW: Each of our cells has the same DNA. Yet they somehow differentiate into different body parts - eyes, ears, skin, and so on. There is no information in the DNA that tells our cells what to be. How then do they do it? This is just one example of how contrary to what many might think, DNA does not explain every problem state in biology. Biology has placed too much emphasis on our genes, trying to explain every disease state using genes, when the answer might not reside with them. What if answers to these questions lies with cells? Even though Dr. Martinez started off as a geneticist, he decided to pivot to understand the properties of cells better. By understanding our cells better, we can make further progress in understanding disease, longevity, and development. Towards the end, we also talk about Alfonso's fascinating work on gastruloids which are a model to unravel the mysteries of embryonic development, and understand how humans are formed. This conversation is about the cell’s eye view of biology, and how the gene's eye view of biology might have mislead us. We also talk about why the popular selfish gene theory espoused by Richard Dawkins is incomplete. Looking beyond genes is instrumental to making progress in longevity.

The following is a fascinating interview with Dr. Charley Lineweaver, who worked with Paul Davies on his work on cancer which we discuss. Episode Show Notes: https://livelongerworld.com/p/clineweaver Topics include: - the evolutionary and atavistic theory of cancer - the incorrectness of the somatic mutation theory of cancer - a novel take on attacking the weakness of cancer - how embryogenesis could be viewed as cells reverting to old memory - the origins of multicellularity - “Cancer cannot do anything new” The atavistic theory of cancer states that cancer cells revert to an old memory they have from billions of years, but forget the new memory. The old memory pertains to constant cell proliferation, which happened as single-celled creatures, and in fact in embryogenesis as well. The new memory pertains to regulating cell proliferation and cells knowing when to stop cellular division. In cancer, it seems like cells forget this new memory and revert to the old memory. This theory has many interesting explanations and predictions which we dive into in the conversation. Enjoy!

Stephanie Seneff is the pioneer in raising concerns around glyphosate, a chemical and active ingredient in RoundUp and other pesticides, which has practically infiltrated our food system, water bodies, and soil. Glyphosate has been linked to several diseases including liver disease, autoimmunity, neurological disorders, reproductive issues, microbiome problems, and more. Dr. Stephanie Seneff has spent 10+ years researching glyphosate’s harmful impact on our health, and documented her findings in her book Toxic Legacy: How the Weedkiller Glyphosate is Destroying our Health and the Environment. More recently, Stephanie has been doing research on deuterium (a hydrogen isotope in the body) and how glyphosate can cause an excess of deuterium, potentially leading to cancer and other health consequences. Glyphosate is affecting each one of us. It’s worth paying attention to this toxic chemical. Episode Show Notes: https://livelongerworld.com/p/sseneff Find me (Aastha) on X: https://x.com/aasthajs DR.

This is the first of several interviews Michael Levin and I will do with significant people in the history of developmental bioelectricity. Richard Nuccitelli is a legend, having invented (with Lionel Jaffe, in 1974) the Vibrating Probe - a technique that allowed the non-invasive sensing of ion currents around living tissues. This is about a ~1 hour conversation in which he talks about his background, the history of the field, and his current clinical work on the bioelectrics of cancer. Episode Show Notes: https://livelongerworld.com/p/rnuccitelli Find me: https://twitter.com/aasthajs BACKGROUND: In 2022, I interviewed Dr. Michael Levin on his work on bioelectricity in cells and how that has the potential to solve cancer and aging. Since then, Mike has also appeared on Lex Fridman and many other podcasts talking about his revolutionary work. Amongst all the podcasts I did, Mike’s work struck me as profound yet underappreciated. The field of biology has focused on the DNA and the relevance of the electric currents in our cells is not appreciated. Yes, the electrical energy powering our cells is what keeps us alive! Earlier this year, I decided to dive deeper into bioelectricity. I’m starting by exploring the history of the field in conjunction with Michael Levin. We’re doing a series of interviews talking to scientists in the field to understand the origins of the field, bottlenecks, progress so far, and what the future could look like. Today's interview is the first in the series with Dr. Richard Nuccitelli.
