    New Theory of Aging: Humans vs. Pathogens

    The standard “wear and tear” story of aging may be incomplete. Dr. Peter Lidsky—a virologist and evolutionary biologist argues that aging is programmed. He says aging can be an adaptive strategy for controlling pathogens, a concept he calls the “pathogen control hypothesis.” In this episode, we dig into the evidence behind this idea, the immune system in aging, and what his theory means for longevity interventions.

    Optimize Cancer Therapy Using Evolution | Michael Levin & Robert Gatenby

    “We can use the rule of evolution to optimize cancer therapy. The standard practice is that any therapy is given at maximum tolerated dose continuously until progression. It's almost a mantra that they have. Evolutionarily, you could hardly do it worse.” The current treatments on cancer do not account for how evolution works. Dr. Robert Gatenby has been studying evolutionary and game theory dynamics in the progression of cancer. He established the first cancer biology and evolutionary program in the U.S. We can leverage this evolutionary information to provide more effective cancer treatment, which he discusses in this episode. Dr. Michael Levin is my co-host.Episode Show Notes: https://livelongerworld.com/p/rgatenbyFind me: https://x.com/aasthajs My longevity products: https://www.livelongerworld.com/p/2024TIMESTAMPS:0:00 – Cancer as Tissue Damage, Not Just Mutations8:48 – How Evolution Supercharges Cancer Cell Fitness11:04 – Debunking the “Primitive Cell” Myth12:06 – The Herd Mentality of Cancer Cells14:57 – Why Cancer Dynamics Go Beyond the Genome22:27 – Networks and Information Flow Inside Cells26:56 – Shared Goals: The Secret to Cellular Cooperation29:55 – Genome = Hardware, Information = Software36:26 – Healthy vs. Cancer Cells: Competing Information Systems39:05 – Evolution Turns Harsh After Reproduction41:03 – How Cancer Rewrites Its Own Information Playbook43:07 – Adaptive Therapy: A Patient’s Guide50:45 – The Limits of Adaptive Therapy53:12 – Hunting for Better Cancer Biomarkers55:11 – The Tumor Microenvironment’s Hidden Role59:42 – Why We Must Look Beyond Genetic DataAASTHA, LIVE LONGER WORLD:X: https://x.com/aasthajs Newsletter: https://livelongerworld.com/Instagram: https://www.instagram.com/aasthajs/LINKS:Michael Levin: https://x.com/drmichaellevinRobert Gatenby: https://www.moffitt.org/inspiring-stories/dr.-gatenbys-storyEpisode Show Notes: https://livelongerworld.com/p/rgatenbyALSO WATCH:The First Cancer Cell: A Revolution in Early Detection | Michael Levin & Azra Raza: https://open.spotify.com/episode/7yW6ZVVdQkboWpldUZyenD?si=obYEC22NSsSyy7j09JBf7QKeto & Metabolic Therapy for Cancer | Dr. Thomas Seyfried: https://open.spotify.com/episode/7tYdjcJ3G4tqbAx9Z6Bix2?si=Yz9CQ-wNQ3WdcwjKw3lXGwWhy Viruses Could Be the Cause of Chronic Disease | Dr. Paul Ewald: https://open.spotify.com/episode/2OdYInlzTy2zG3Mi6TgADY?si=BtishVk_R-28K2KypODIog

    Live to 130 with new mitochondria | Tom Benson, Mitrix Bio on Mitochondrial Transplantation

    Mitochondria might be one of the most important organelles inside our cells. Best known as the cell’s powerhouse, they don’t just make energy; they regulate metabolism, control cell death, drive immune function, and may even be the reason multicellular life exists at all! It’s no surprise they’re implicated in nearly every major disease, from heart disease and cancer to neurodegeneration, especially as they decline with age. What if we could slow or even reverse that decline by giving cells fresh, healthy mitochondria? That’s the promise of mitochondrial transplantation—a groundbreaking approach Mitrix Bio is pioneering. In this episode, I talk with CEO Tom Benson about the science, the potential, and the early results from people already lining up for their trial.

    Detect the First Cancer Cell | Michael Levin & Azra Raza

    Can we detect cancer so early such that we find the very first cell of cancer? Not just stage 1 cancer, but the first cell of cancer. In this episode, Dr. Michael Levin and I speak with Dr. Azra Raza. She is an oncologist pioneering early detection of cancer using electric signals. So far, our best solution to curing cancer has been to detect it early, and she wants to take this further, by nipping cancer at the very first cell. Her story with cancer is also deeply personal as she lost her husband to the disease. You can see in the episode how much she cares about solving cancer through early detection, and how aggrieved she is about the fact that not only have we made zero progress on cancer in the last 100 years, but doctors are also not focused on cancer prevention. Dr. Raza is also the author of the book The First Cell: And the Human Costs of Pursuing Cancer to the Last.

    Hidden Viruses Cause Cancer & Alzheimer's | Dr. Paul Ewald

    What if chronic diseases like cancer and Alzheimer’s are caused by infections we’ve overlooked? We assume chronic disease is caused by genetics and / or lifestyle. However, evolutionary biologist Dr. Paul Ewald says latent viruses and pathogens play a critical hidden role in many diseases. For example, we already know that Human Papillomavirus (HPV) causes cervical cancer. And research indicates how the EBV virus shows up in Multiple sclerosis, and chlamydia pneumonia shows in Alzheimer’s. Deeper investigation into viruses and disease is warranted and will help with better diagnosis and treatment. Dr. Paul Ewald is also the author of Plague Time: The New Germ Theory of Disease, and Evolution of Infectious diseases.

    Keto Diet & Metabolic Therapy for Cancer | Dr. Thomas Seyfried

    Dr. Thomas Seyfried challenges the existing paradigm that says cancer is a genetic disease. He says that instead cancer is caused by damage to the mitochondria. Understanding this completely overturns the management and prevention of cancer. He is a Professor of biology, genetics, and biochemistry at Boston College. He has over 150 peer-reviewed publications and is also the author of books such as, ‘Cancer as a Metabolic Disease: On the Origin, Management, and Prevention of Cancer’. WE DISCUSS: - Why cancer is not a genetic disease - Why cancer is a metabolic disease originating from damage to the mitochondria - How metabolic therapy, management of glucose and glutamine, can be used to manage cancer - His December 2024 paper outlining a proposal for ketogenic metabolic therapy in glioblastoma Episode Show Notes: https://livelongerworld.com/p/tseyfried Find me: https://x.com/aasthajs TIMESTAMPS: 0:00 Cancer is not a genetic disease 5:04 Origins of somatic mutation theory of cancer 8:04 Mitochondrial damage causes cancer 13:42 Is mitochondrial dysfunction involved in every cancer 16:14 Mitochondria in cancer cells ferment 21:52 Target glucose and glutamine to manage cancer 28:51 Hyperbaric Oxygen therapy for cancer 31:04 December 2024 study: Role of glutamine in cancer 33:35 Can metabolic therapy be done at any stage of cancer 36:44 Combine chemotherapy with metabolic therapy 38:05 Drugs to target glutamine 40:30 People will say “I want metabolic therapy” 44:04 “Failure to understand biology” 47:48 National Cancer Institute’s take on Dr. Seyfried’s theory 49:34 Why does Peter Attia think cancer is a genetic disease 53:09 “I think about this 24/7; we’re right!” 55:56 Glioblastoma treatment protocol study 59:22 Resistance to breakthrough ideas in science 1:01:40 Radiation fuels cancer! 1:04:52 Current standard of care is responsible for poor survival rate in glioblastoma 1:07:14 Metabolic therapy for epilepsy, Parkinson’s, Alzheimer’s 1:12:22 How to prevent cancer 1:13:49 Young, healthy individuals in their 20s, 30s with cancer 1:15:05 Resources on following metabolic therapy 1:17:43 How to support Dr. Seyfried’s research 1:18:51 New cancer questions Dr. Seyfried is researching 1:21:32 Closing thoughts AASTHA, LIVE LONGER WORLD: X: https://x.com/aasthajs Newsletter: https://livelongerworld.com/ Instagram: https://www.instagram.com/aasthajs/ DR.
