Registered dietitian Leyla Muedin discusses a Frontiers in Microbiology paper suggesting certain probiotics may help sequester heavy metals. The study, sponsored by the Italian company Probiotical and conducted with University of Ghent and University of Piedmont Orientale, researchers used in vitro testing and the SHIME gut simulator to assess Lactiplantibacillus plantarum, Lactobacillus crispatus, and Lactobacillus acidophilus against cadmium, lead, chromium, and mercury. L. plantarum and L. crispatus reduced metal bioavailability primarily in the simulated colonic phase, while L. acidophilus showed minimal detoxification; mercury was least reduced (~10%). An ex vivo mouse-intestine system found probiotic pre-incubation of metals preserved epithelial integrity and reduced inflammatory responses. Leyla notes limitations: corporate funding, only three strains tested, and no in vivo or human trials, though the findings support further animal and clinical research.

Fish Oil Supplements And Alzheimer's-Related Decline A two-year randomized, double-blind, placebo-controlled trial led by researchers at USC tested whether 2,000 mg of DHA fish oil daily could slow Alzheimer's-related brain changes in 365 adults ages 55–80 who rarely consumed fish and had at least one Alzheimer's risk factor. Researchers confirmed the supplement reached the brain by measuring a roughly 17% increase in cerebrospinal fluid DHA after six months. Despite successfully increasing brain DHA levels, participants taking fish oil showed no significant improvements in memory, global cognitive function, or hippocampal volume compared to placebo after two years. Host Dave Asprey explains why raising a single biomarker doesn't always translate into better brain performance, why nutrition works differently inside a complete dietary pattern than as an isolated supplement, and what this study means for anyone relying on fish oil as an Alzheimer's prevention strategy. Sources: https://medicalxpress.com/news/2026-06-fish-oil-supplements-alzheimer-decline.pdf https://www.cnn.com/2026/06/18/health/omega-3-fish-oil-algae-supplement-wellness ~~ DASH Diet Showed the Strongest Link to Long-Term Brain Health Researchers from Harvard analyzed dietary data from 159,347 participants across three long-running U.S. health studies to examine how eating patterns influence cognitive aging. Participants completed dietary questionnaires every four years over several decades, allowing investigators to compare six healthy dietary patterns, including the DASH and Mediterranean diets. While all six were associated with better cognitive health later in life, adherence to the DASH diet produced the strongest association, with participants showing roughly a 40% lower risk of subjective cognitive decline and stronger performance on objective cognitive testing. The protective relationship was strongest when healthy eating habits began during midlife. Host Dave Asprey breaks down why blood sugar control, lower inflammation, and healthier blood vessels may be the real drivers behind long-term brain resilience, and why your dietary choices in your 40s and 50s may have an outsized impact on cognitive aging decades later. Sources: https://jamanetwork.com/journals/jamaneurology/article-abstract/2845466 https://www.health.harvard.edu/diet-and-nutrition/harvard-study-six-healthy-diets-linked-with-better-long-term-brain-health https://www.eurekalert.org/news-releases/1117225 ~~ Scientists Identified an Ancient Brain Circuit That Filters Distractions Johns Hopkins researchers discovered a small population of inhibitory neurons within an evolutionarily ancient brainstem region that appears to control selective attention by determining which sensory information deserves focus and which distractions should be ignored. Mice trained on visual attention tasks consistently ignored irrelevant stimuli until researchers temporarily silenced these neurons, causing even weak distractions to hijack their attention while leaving vision and movement otherwise unaffected. Similar brain circuits exist in birds, reptiles, and other vertebrates, suggesting this attentional filtering system evolved long before the modern human cortex. Host Dave Asprey explains why attention may depend on much older brain circuitry than previously believed, how this discovery could reshape our understanding of ADHD and autism, and why future therapies may target the brainstem instead of the prefrontal cortex. Sources: https://www.sciencedaily.com/releases/2026/06/260624025426.htm ~~ Nearly Half of Older Adults Improved With Age Instead of Declining A Yale-led study followed 11,340 adults age 65 and older for up to 12 years using repeated measurements of cognition and walking speed to better understand how aging changes over time. Rather than finding universal decline, researchers discovered that 45% of participants improved in either cognitive function, physical performance, or both. Nearly one-third experienced measurable cognitive improvements, while over one-quarter improved physically. Researchers also found that participants with more positive beliefs about aging were significantly more likely to improve, even after accounting for education, chronic illness, depression, and other health factors. Host Dave Asprey explores why expectations about aging may become biologically embedded, why decline is far less inevitable than conventional medicine often assumes, and how mindset may directly influence healthy longevity. Sources: https://www.sciencedaily.com/releases/2026/06/260620100428.htm ~~ Glyphosate May Be Contributing to Antibiotic-Resistant Superbugs Researchers publishing in Frontiers in Microbiology examined 102 bacterial strains collected from hospitals, agricultural land, and protected wetlands to investigate whether glyphosate exposure contributes to multidrug antibiotic resistance. Hospital bacteria demonstrated extensive resistance to both antibiotics and glyphosate, while even bacteria living inside protected nature reserves displayed measurable glyphosate resistance despite no direct herbicide application. Genetic analysis suggested resistant bacterial strains may move between agricultural environments and hospitals through shared waterways and sediments. The researchers argue pesticide safety testing should also evaluate whether chemicals encourage antibiotic resistance, one of the world's fastest-growing public health threats. Host Dave Asprey explains why environmental toxins may have unintended effects on the human microbiome, how herbicides could influence antimicrobial resistance beyond farming, and why environmental biology increasingly belongs in conversations about human health. Sources: https://www.sciencedaily.com/releases/2026/06/260620100434.htm https://www.openaccessgovernment.org/common-weedkiller-glyphosate-linked-to-rise-in-superbugs-scientists-warn/207515/ ~~ Butterflies That Barely Age Could Unlock New Longevity Pathways Researchers from the University of Bristol found that Heliconius butterflies live dramatically longer than closely related butterfly species while aging much more slowly. In one comparison, Heliconius hewitsoni survived up to 348 days, while a closely related species lived only 14 days. Unlike most butterflies, Heliconius feed on pollen throughout adulthood, providing amino acids that help preserve muscle function and physical performance with age. However, even when pollen was removed, these butterflies still significantly outlived their relatives, suggesting evolved genetic and metabolic mechanisms also contribute to their exceptional longevity. Host Dave Asprey explores why nature continues to provide unexpected models for slowing biological aging, what scientists hope to learn from species that naturally maintain function over time, and how comparative biology may uncover entirely new pathways for extending human healthspan. Sources: https://www.sciencedaily.com/releases/2026/06/260622014302.htm ~~ This episode is designed for biohackers, longevity enthusiasts, and high-performance listeners who want mechanism-level insights into omega-3 supplementation and Alzheimer's prevention, nutrition strategies for preserving cognitive health, newly discovered brain circuits controlling attention, the surprising biology behind healthy aging, environmental drivers of antibiotic resistance, and what one remarkably long-lived butterfly can teach us about extending healthspan.

TWiM visits Tufts University School of Medcine and are joined by John Coffin, Michael Malamy, and Verna Manni for a tribute to Elio Schaechter who was chair of Molecular Biology and Microbiology for 23 years.
The name "Dr. Jonas Salk" is synonymous with one of the greatest public health achievements of all time: The Polio Vaccine. The arrival of Salk's vaccine in 1955 was a beacon of hope and reinforced the role science can play to serve the public good. When asked who owned the patent for the vaccine, Salk famously replied, "There is no patent. Could you patent the sun?" In 1994, and just one year before Dr. Salk passed, polio was considered eliminated in North and South America. Today, vaccine hesitancy - driven by a host of reasons - has eroded childhood immunization rates in some parts of the country, and reignited a debate over vaccines as a stress test for public trust in science.rnrnContinuing the work of Dr. Jonas Salk is his son, Dr. Peter L. Salk. A graduate from Harvard University and Johns Hopkins University School of Medicine, he would go on to work in his father's laboratory at the Salk Institute for Biological Studies from 1972 to 1984, and again from 1991 to 1995. Together, they would research the biology and immunotherapy of cancer and autoimmune diseases, and develop an inactivated vaccine for HIV infection. Nowadays, Dr. Salk spends his time educating the public regarding his father's life and work and exploring approaches to reducing the severity of various public health problems. Since 2009, Dr. Salk has served as president of the Jonas Salk Legacy Foundation in La Jolla, California. He is also an adjunct professor at the University of Pittsburgh's School of Public Health, Department of Infectious Diseases and Microbiology.rnrnIn partnership with the Mt. Sinai Health Foundation, join us as Dr. Peter L. Salk sits down in conversation with Dr. Arthur Lavin, retired pediatrician and Co-Founder of Grandparents for Vaccines. Together, they will discuss the Salk legacy, the state of public trust in science, and the future of public health.
Your gastrointestinal tract is home to hundreds of bacterial species that play essential roles in digestion and metabolism. As this field of research expands it is becoming increasingly clear that these microbes influence systems beyond the gut: they can even impact brain functioning. These effects were once thought to occur indirectly over the span of minutes to hours through complex chemical signaling pathways. Over the past 15 years, however, scientists have discovered that gut bacteria can communicate directly with the brain via the nervous system, transmitting signals in a matter of seconds and reshaping how we understand the gut–brain axis. This week, we're joined by Kevin Rice, a fourth-year PhD candidate in the Department of Microbiology, co-advised by Dr. Maude David and Dr. Kenton Hokanson. Kevin's research focuses on how human gut cells interact with neurons and the role that the microbiome may play in influencing neurodevelopmental disorders. Through his work across both Microbiology and Biochemistry & Biophysics, he combines computational approaches with neuroscience techniques to better understand the big impact our microbial communities can have on human health. Tune in this Sunday, June 7th at 7 PM to hear Kevin talk about how pursuing scientific questions has shaped his perspective on what constitutes a worthwhile career and the implications of his work in understanding neurodevelopmental disorders.

Nicholas Monsul (Yale University & The Johns Hopkins Hospital) and Dr Eva Berkes (Scripts Inst.) are physician-scientists and co-founders of Quorum Innovations, a biotechnology company working with bacteria to achieve extraordinary results. They have an innovative biofilm, postbiotic technology that binds 98% microplastics in the digestive tract with human trial results now live and a recently published paper.This is the first publication to demonstrate a technology capable of binding plastics to a bacterium in the digestive tract, in humans. The paper is currently under review in the Journal “Frontiers of Microbiology”. Very exciting stuff and I can't wait for you to dive into the show.

Think energy, digestion, and weight. In this episode, Nurse Doza breaks down berberine — the metabolism-supporting supplement that helps regulate blood sugar, support a healthy insulin response, and improve cholesterol (LDL, HDL, total). Discover why MSW Nutrition's Berberine Plus is 5x more absorbable in the gut, how to dose it morning and night, and why it works at the level of your gut microbiome. The berberine supplement your metabolism has been waiting for. Featured Partner: MSW Nutrition — Berberine Plus MSW Nutrition's Berberine Plus delivers dihydroberberine (DHB) — the bioactive, highly absorbable form of berberine sourced from Berberis aristata — so you get berberine's full metabolic benefits at a fraction of the dose, without the gut upset that comes from mega-dosing standard berberine. That enhanced absorption is exactly why it's the berberine supplement Nurse Doza reaches for to support blood sugar, digestion, and weight — as discussed in this episode.
As concerns escalate about the deadly Ebola virus outbreak in Africa, we bring you the unique insights of Dr. Peter Piot, a renowned microbiologist who co-discovered the virus 50 years ago during the first recorded outbreak of the disease. His on-the-ground account of that crisis was provided to us in April before the current outbreak was declared, but it contains valuable historical perspective and shares lessons learned that he carried forward in his consequential career. “What I saw from the beginning is the most important thing is to listen to people and that you need to act fast to save lives, before you have the evidence you would like to have.” He followed his contributions on Ebola by diving into the fight against HIV/AIDS, eventually reshaping global response in leadership roles at the World Health Organization and United Nations. As he shares with host Lindsey Smith, the learnings in that case were more pragmatic than scientific. “We had to redefine HIV/AIDS not as a medical problem but as an economic and security problem in order to get it on the political agenda.” Tune in for a fascinating episode that takes you from the gritty frontlines of public health crises to the battles for funding and attention in the halls of power as Dr. Piot shares what it actually takes to move the world to respond effectively to health threats.

The EU has just announced that single-use sauce sachets like you would find in restaurants are to be banned from mid-August, leading to communal sauce bottles being used. But, what might this mean in terms of the spreading of germs?Joining Shane to discuss is Dr Orla Cahill, a Lecturer in Microbiology and Allergen Management at TU Dublin.
This month, Mary met up with Dr. Beronda Montgomery, a plant biologist, writer, researcher and scholar. Dr. Montgomery works to understand how individuals perceive, respond to, and are affected by the environments in which they live. By investigating the response of photosynthetic organisms (i.e., plants and cyanobacteria) to external light cues, she is able to identify related roles for innovative leaders in human settings.After over 18 years at Michigan State University as a Foundation Professor in Biochemistry, Molecular Biology, Microbiology and Molecular Genetics, Beronda served as Vice President for Academic Affairs, Dean, and Professor of Biology at Grinnell College. In that time, she co-founded the annual Black Botanists Week. Then, since 2025, she's been the Sally Starling Seaver Fellow in Biological Sceinces with Radcliffe Harvard Institute.In this episode, Mary and Beronda speak of her most recent book, When Trees Testify. As Beronda writes, "Plants don't just passively provide. They also take action. They are masters of adaptation. They 'know' what and who they are, and they use this knowledge to make a way in the world. Plants are even capable of transformative behaviors that allow them to maximize their chances of survival in dynamic and sometimes unfriendly environments." Quite consistent with the rich spirit of her words here, this HILFH conversation was rich and enlivening. You can learn more about Beronda Montgomery by checking out her books, When Trees Testify and Lessons from Plants. Also spend some time with her website and the additional writings there. Let yourself be informed and inspired by Dr. Montgomery and the love of plants.MUSICRolled Ankles. Music by Nicholas Panek from PixabayMoonlight on Your Hands.

10 million deaths a year. That is how many people are predicted to die from antibiotic-resistant infections if we do not find new treatments. In today's episode, Professor Martha Clokie and Professor Tim Spector explore the secret gut viruses, known as phages, being studied to fight deadly infection, target cancer cells, and to protect your gut microbiome. Martha is a world-leading expert on the mysterious phage and, for the last 20 years, has pioneered research to revolutionise the treatment of infections without antibiotics. She explains why antibiotic resistance is a growing global threat, why everyday infections are becoming harder to treat, and how some bacteria are now resistant to every antibiotic available. We explore how the viruses in our gut may help solve this problem, and how scientists may one day use them to deliver highly targeted cancer treatment. By the end of the episode, you'll have some ideas to help support a healthier gut ecosystem and understand how to increase the number of friendly gut viruses that live inside you. The science is still early, but the message is clear: the small choices we make every day are shaping our long-term resilience to disease. If viruses can help protect us from infection rather than cause it, how much of human health are we only just beginning to understand?
Save 20% on all Nuzest Products WORLDWIDE with the code MIKKIPEDIA at www.nuzest.co.nz, www.nuzest.com.au or www.nuzest.comThis week on the podcast, Mikki speaks to Dr Matt Nagra, a naturopathic doctor and researcher known for his evidence-based perspective on nutrition, with a particular focus on plant-based diets and chronic disease.In this episode, the conversation tackles one of the most debated topics in nutrition right now: protein. Matt helps unpack why protein has become such a focal point, how to interpret the current evidence, and what outcomes actually matter when we're talking about intake and health. They explore the long-standing protein RDA and what it was designed to represent.The discussion then moves into protein quality, addressing common claims around plant versus animal protein, and why mechanistic research doesn't always align with long-term health outcomes. Matt also provides important context around dietary patterns and chronic disease risk, helping to separate the role of protein itself from the broader way people eat.They finish with a dive into choline, covering its role in the body, how it interacts with other nutrients like folate and betaine, and what this means for people following predominantly plant-based diets.It's a thoughtful, nuanced conversation that cuts through the noise and brings clarity to some of the biggest questions in modern nutrition.Dr Matt Nagra is a naturopathic doctor who graduated from the Boucher Institute after completing a Bachelor of Science in Microbiology at the University of Victoria. He holds additional board certifications in prescriptive authority, immunisations, advanced injection therapies, intravenous therapies, and acupuncture. Using an evidence-based approach, he creates individualised treatment protocols tailored to each patient's health goals and lifestyle.He has a particular passion for plant-based and vegan nutrition, physical medicine, and chronic disease treatment. With additional training in nutrition, he holds a Plant-Based Nutrition Certification from Cornell University and the T. Colin Campbell Center for Nutrition Studies, where he has also authored multiple articles. His work aims to support individuals in thriving on plant-based diets, while bridging the gap between lifestyle-based interventions and medical care.Choline paper: https://www.academia.edu/3067-1345/2/4/10.20935/AcadNutr8085Instagram: @dr.matthewnagraDr. Nagra's website Curranz Supplement: Use code MIKKIPEDIA to get 20% off your first order - go to www.curranz.co.nz or www.curranz.co.uk to order yours NZ listeners - save 10% off Calocurb by using the code Mikkipedia10 at www.calocurb.co.nzContact Mikki:https://mikkiwilliden.com/https://www.facebook.com/mikkiwillidennutritionhttps://www.instagram.com/mikkiwilliden/https://linktr.ee/mikkiwilliden

While the gut microbiome often steals the spotlight, the microorganisms residing in our respiratory tract play a vital role in our health and immunity. In this episode, Dr. Sheena Fraser sits down with microbial ecologist Dr. Michael Cox to explore the fascinating, complex, and relatively uncharted territory of the lung microbiome.They discuss how the lung microbiome fundamentally differs from the gut, the daily flux of bacteria entering and leaving our airways, and the profound impacts of environmental factors like air pollution, smoking, vaping, and household cleaning products. Plus, Dr. Cox shares the massive challenges scientists face when studying these deep-tissue microbes and what the future of respiratory medicine might look like.What We Cover:From Seawater to Sputum: Using marine ecology techniques to decode human respiratory biology.Exploring the lungs' dynamic balance of microaspiration and mucociliary clearance.Meet the core lung bacteria (Streptococcus, Prevotella, Veillonella) and the puzzle of anaerobes in an oxygen-rich space.Environmental Disruptors: How pollution, smoking, and vaping inflame and alter the lung microbiome.Hidden Dangers of VOCs: The silent impact of everyday cleaning sprays and aerosols on respiratory health.Diet, Exercise, & Epigenetics: The systemic benefits of a high-fiber diet and fitness for chronic lung conditions like COPD and asthma.About Dr. Michael Cox is a microbial ecologist and the PGR Lead for the Institute of Microbiology and Infection at the University of Birmingham. His research focuses on the bacteria that reside in the respiratory tract in the context of respiratory diseases (such as COPD and Cystic Fibrosis). His lab works to understand the function of the respiratory microbiome, translate these findings for clinical benefit, and expand our understanding of the respiratory ecosystem beyond just bacteria.Connect with Dr Michael Cox:University of BirminghamScientific References & Further Reading:Cumming, K.

Meet Insect Agriculture with Dr. Heather Jordan & Cheryl PreyerPub date: 2026-05-05Get Podcast Transcript →powered by Listen411 - fast audio-to-text and summarizationMost people have never heard of insect agriculture. By the end of this episode, you'll wonder how you missed it.Bites & Bytes Podcast host Kristin King sits down with Dr. Heather Jordan, microbiologist, professor at Mississippi State University, and site director for the NSF-funded Center for Insect Biomanufacturing and Innovation (CIBI), and Cheryl Preyer, the center's industry liaison and former fast food executive, to unpack one of the most quietly consequential shifts happening in the global food system right now.For consumers, this is where your food waste is going next and why that matters for everything from the fish on your plate to the cost of your groceries. Black soldier fly, cricket, and mealworm farming aren't science fiction. They're converting food waste into high-quality livestock feed, fertilizer, and protein at scale. Research is even showing promise in using these insects to remove plastics, antibiotics, and heavy metals from our environment.For professionals in cyber-physical risk, OT security, and food and agriculture cybersecurity, pay attention. Insect agriculture facilities are automated, sensor-dependent production environments with real operational technology vulnerabilities, and this industry is scaling fast with limited security frameworks in place (aka a factory) This is the circular bioeconomy in action. And it already exists.---------------Guest Contact Information:Dr. Heather JordanProfessor of Microbiology and Molecular Biology, Mississippi State University, and Site Director, Center for Insect Biomanufacturing and Innovation (CIBI)Cheryl PreyerIndustry Liaison Officer, Center for Insect Biomanufacturing and InnovationCenter for Insect Biomanufacturing and Innovation ---------------Episode Key Highlights 00:08:01 — "I Traded Fries for Flies" — Cheryl's Origin Line00:11:49 — Insect Farming Is Livestock Farming00:12:37 — "Feed the Food That Feeds Us."00:16:02 — What a Black Soldier Fly Actually Does as an Adult00:23:19 — Why Organic Chickens Need Synthetic Methionine00:23:50 — The Lauric Acid and Coconut Connection00:28:34 — Using Everything But the Oink00:39:51 — The Cricket Densovirus Crisis That Wiped Out Facilities00:50:15 — Heather's West Africa Origin Story---------------

Today, we're diving into autoimmunity—what it actually is, why it happens, and how ultra-processed foods may be contributing to the problem. Autoimmune disease is often misunderstood. Some will tell you diet has nothing to do with it. Others claim diet is the cure. The truth is more nuanced—and that's exactly what we explore in this episode. You'll learn: What autoimmunity really is (and why it's a case of mistaken identity) How inflammation and the immune system interact The critical role of gut health and the microbiome How ultra-processed foods disrupt intestinal integrity and immune signaling Why stress and hyper-palatable foods create a harmful cycle A practical experiment you can try to see how diet impacts your own biomarkers This isn't about selling supplements or pushing extremes. It's about understanding the science so you can make informed decisions about your health. As always, this episode is backed by scientific literature. Full citations are included below, with abbreviated versions available on shorter clips. If you're dealing with autoimmune symptoms—or just want to better understand how food impacts your immune system—this episode is for you. Full citation list: Hall KD, et al. “Ultra-Processed Diets Cause Excess Calorie Intake and Weight Gain: An Inpatient Randomized Controlled Trial of Ad Libitum Food Intake.” Cell Metabolism, 2019. Supports the formulation argument: UPF intake increased spontaneous calorie intake and weight gain even with diets matched for presented calories, sugar, fiber, sodium, and macronutrients. This is your anchor for “hyper-palatability and formulation change physiology, not just psychology.” Narula N, et al. “Association of Ultra-Processed Food Intake With Risk of Inflammatory Bowel Disease: Prospective Cohort Study.” BMJ, 2021. Best human disease-level citation for the episode. Supports the claim that higher UPF intake is associated with greater IBD risk, making the gut-immune link clinically meaningful rather than purely theoretical. Chassaing B, et al. “Randomized Controlled-Feeding Study of Dietary Emulsifier Carboxymethylcellulose Reveals Detrimental Impacts on the Gut Microbiota and Metabolome.” Gastroenterology, 2022. Best emulsifier paper for human translation. Supports the claim that CMC can perturb the microbiota and metabolome and may contribute to barrier-hostile gut ecology in susceptible individuals. Daniel N, et al. “Human Intestinal Microbiome Determines Individualized Responses to Dietary Emulsifier Carboxymethylcellulose.” Cellular and Molecular Gastroenterology and Hepatology, 2024. Useful nuance paper. Supports the point that emulsifier sensitivity is not identical across all people and that host-microbiome context matters. Shil A, et al. “Artificial Sweeteners Disrupt Tight Junctions and Barrier Function in the Intestinal Epithelium Through Activation of the Sweet Taste Receptor T1R3.” Nutrients, 2020. Best citation for the “sugar-free does not mean barrier-neutral” point. Supports direct epithelial barrier effects of common artificial sweeteners in experimental models. Peng L, et al. “Butyrate Enhances the Intestinal Barrier by Facilitating Tight Junction Assembly via Activation of AMP-Activated Protein Kinase in Caco-2 Cell Monolayers.” Journal of Nutrition, 2009. Classic mechanistic citation for butyrate. Supports the claim that loss of fermentable fiber and reduced butyrate production can weaken barrier function. Kumar KP, et al. “The Interplay Between the Microbiota, Diet and T Regulatory Cells in Maintaining Intestinal Homeostasis.” Frontiers in Microbiology, 2023. Useful for the tolerance language. Supports the argument that diet and microbial metabolites shape Treg biology and mucosal tolerance. Haase S, et al. “Sodium Chloride Triggers Th17 Mediated Autoimmunity.” Frontiers in Immunology, 2019. Key citation for high salt and autoimmune-prone immune skewing. Supports the claim that excess salt can promote pathogenic Th17 biology relevant to autoimmune disease. Wilck N, et al. “Salt-Responsive Gut Commensal Modulates TH17 Axis and Disease.” Nature, 2017. Strong bridge between salt, microbiome, and Th17 signaling. Supports the point that salt is not just a blood pressure story; it is also an immune-story. Vitales-Noyola M, et al. “Analysis of Sodium Chloride Intake and Treg/Th17 Lymphocytes in Patients With Rheumatoid Arthritis and Systemic Lupus Erythematosus.” Journal of Immunology Research, 2018. Helpful human-facing citation for salt and immune skewing in autoimmune populations. Use cautiously, but it strengthens translation from theory to autoimmune terrain. Phuong-Nguyen K, et al. “Advanced Glycation End-Products and Their Effects on Gut Health.” Nutrients, 2023. Good review for the AGE section. Supports the argument that AGE-rich processed foods may worsen oxidative stress, microbiota balance, and barrier function. Chen Y, et al. “Dietary Advanced Glycation End-Products Elicit Toxicological Effects by Disrupting Gut Microbiota and Increasing Colon Permeability in Rats.” Journal of Toxicology and Environmental Health, 2021. Useful mechanistic support for the processing-chemistry section. Reinforces the claim that dietary AGEs can alter microbial ecology and increase permeability. Monteiro CA, et al. “Ultra-Processed Foods: What They Are and How to Identify Them.” Public Health Nutrition, 2019. Dr. Brendan McCarthy is the founder and Chief Medical Officer of Protea Medical Center in Arizona.

Floris Regouin is Chief Visionary Officer at The New Tomorrow and author of Natural Intelligence, where he explores how 3.8 billion years of natural R&D can help leaders rethink organizational design, collaboration, resilience, and change.In this episode of Assets UNSCRIPTED, host Berend Booms sits down with Floris to explore how nature's hidden playbook can reshape the way organizations operate. From starling murmuration's and lichen ecosystems to leverage points and adaptation, this conversation examines what leaders can learn from nature about moving smarter, building resilience, and navigating disruption in a world of constant change.He explains:▪️ Why nature offers a more adaptive model for leadership than rigid structures and protocols▪️ What starling murmuration's can teach organizations about alignment, trust, and shared direction▪️ Why resilience comes from diversity, experimentation, and collaboration▪️ How imbalance and disruption can actually drive growth and adaptation▪️ Why leaders need reflection, play, and room to experiment—not just more meetings▪️ What nature reveals about leverage points and using less energy for greater impact▪️ How to think about artificial intelligence through the lens of adaptation rather than fear▪️ Why the real imperative for leaders today is simple: adapt or die00:00 Intro00:00:27 Floris Regouin's Journey from Microbiology to Business00:05:55 Seeing Differently: Why Nature Is the Ultimate R&D Lab00:07:37 What Nature Knows About Optimization and Efficiency00:08:17 Starling Murmurations and the Power of Simple Rules00:12:26 Leadership Without Overcontrol00:17:13 Signals, Shared Direction, and Organizational Alignment00:18:50 The Microsoft Example: When Silos Undermine the Bigger Picture00:23:02 Why Imbalance, Play, and Mistakes Matter00:28:38 Resilience, Ecosystems, and Letting Go of Control00:31:28 Lichen, Symbiosis, and the Strength of Collaboration00:34:26 Parasites, Tension, and What Organizations Can Learn from Friction00:37:09 Leverage Points and the Wisdom of the Eagle Owl00:40:36 Why Leaders Need Reflection More Than More Meetings00:43:51 Moving With the Currents Instead of Against Them00:46:34 AI, Adaptation, and the Future of Work00:54:30 Final ThoughtsThis episode is for asset leaders, operations executives, and anyone rethinking how organizations can become more resilient, adaptive, and human in the face of complexity.Follow Berend Booms on LinkedIn:https://www.linkedin.com/in/berendbooms/Follow Future of Assets on LinkedIn:https://www.linkedin.com/company/future-of-assetsLearn more about Assets UNSCRIPTED:https://www.futureofassets.com/Learn more about the UNSCRIPTED podcasts:https://www.futureoffieldservice.com/podcast/
Misha Glenny and guests discuss one of the most remarkable scientific discoveries of the 20th century: the archaea microorganisms. In the 1970s the American microbiologist Carl Woese (1928-2012) realised that the tiny bacteria-sized organisms he was studying were not actually bacteria but from an entirely different branch of the tree of life. It became clear that archaea, as he named them, share aspects of the cells in all plants and animals even if they often live in places where other life struggles including salty lakes, acidic pools, under the sea bed and in the gut. While aspects of what followed from Woese are still under debate, further discoveries suggest that life on Earth has been on a journey of separation and reunion: that the first cells developed into bacteria and archaea billions of years ago and that some of those later combined to form the complex cells from which we are made.

Send us Fan MailImagine a life form identical to your own, only backwards.At first, it would look normal. But just like when you try to use a mirror to read text on a page, it doesn't quite translate. For some reason, all of the DNA of life on Earth is right-handed. The double helix of DNA that codes for all life on the planet spirals to the right – a quality called chirality. But, in theory, scientists could build cells based on DNA that spirals to the left. These mirror cells could defy some of the rules of biology. While it's not clear how they might be useful, several labs sought to examine the possibility. Some of the U.S. scientists who took a look were startled by the implications and put together a team of 35 experts who studied the risks.Mirror bacteria, in particular, scared them. Like an invasive plant that local animals don't recognize as potential food, mirror bacteria could evade the immune systems of animals and people and cause life-threatening infections, they reported. They could wreak havoc on crops and even on entire ecosystems. The experts' December 2024 report recommended halting all work on mirror cells.In this One World, One Health episode, one member of that committee, Dr. Jassi Pannu, explains some of what the team found. Dr. Pannu is a Senior Scholar at the Johns Hopkins Center for Health Security and an Assistant Professor in the Department of Environmental Health and Engineering at the Johns Hopkins Bloomberg School of Public Health. Listen as she chats with host Maggie Fox about the potential risks of mirror bacteria and how scientists must voluntarily stop this research.
In this quickie episode, we will answer a question from one of our podcast family members: “Can a virgin get BV?”. It's a complicated question, that needs explanation. PLUS, we will relate this to a former “event” from a past president- so listen until the end!1.
