The research behind this is not fringe. A study in the New England Journal of Medicine found microplastics embedded in arterial plaque in over half of 257 surgical patients. Those patients had a 4.5 times higher risk of heart attack, stroke, or death. A 2025 Nature Medicine study found the average human brain now holds roughly a spoonful of microplastic particles, up 50% in just eight years. In dementia brains, the concentration was ten times higher. In this episode, Ben walks through exactly where exposure comes from, what these plastics are doing to your hormones, your metabolism, your inflammation, and your brain, and the simple five-step protocol you can start today. Key takeaways: A single liter of bottled water contains around 240,000 microplastic particles on average One plastic teabag releases 11.6 billion plastic particles into a single cup of hot water BPA mimics estrogen at receptor sites, disrupting testosterone in men and fertility in women Your body stores these chemicals in fat cells through a pathway called PPAR gamma, creating new fat cells if it runs out of room Glutathione is the master molecule your liver uses to neutralize and eliminate these toxins, and modern life depletes it constantly NAC supplies the cysteine your liver needs to produce glutathione internally The five-step protocol: stop heating plastic, filter your water, eat real food, sweat daily, prioritize fiber and hydration Find All The Ben Azadi Show Sponsorship Deals ⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠⁠https://www.ketokamp.com/sponsorship-deals Learn more about your ad choices.

What if there was literally a plastic spoon's worth of microplastics sitting inside your brain right now? In this jaw-dropping and deeply urgent solo episode, Darin Olien breaks down the newest science on microplastics, nanoplastics, brain accumulation, neuroinflammation, endocrine disruption, and the rapidly escalating contamination of the human body. Referencing groundbreaking new research published in Nature Medicine and newly launched U.S. government initiatives, Darin exposes how plastics are no longer just an environmental issue—they are now a human biology issue. From nanoplastics crossing the blood-brain barrier to endocrine-disrupting chemicals like BPA, PFAS, and phthalates accumulating in tissues, placentas, and testes, this episode explores the shocking implications of modern plastic exposure—and, more importantly, what practical steps you can take immediately to reduce your risk.     What You'll Learn The shocking new study finding microplastics in 100% of healthy human brains Why the average brain may now contain roughly a plastic spoon's worth of plastic How nanoplastics cross the blood-brain barrier The alarming connection between microplastics and dementia research Why plastics are not biologically inert substances The endocrine-disrupting chemicals hitchhiking on microplastics How bottled water, tea bags, coffee pods, and

Inside our brains. Inside our blood vessels. Inside unborn children. But while the scale of the problem is staggering, the solution begins with everyday choices. What you drink from. What you heat your food in. What you filter. What you buy. Your body is not a landfill—and reclaiming your health starts with refusing to treat it like one."     Bibliography/Sources Primary Scientific Studies Bornstein, S. R., et al. (2025).

Jonathan Dickinson is the co-founder and CEO of Ambio Life Sciences, one of the world's leading ibogaine clinics. He's spent more than fifteen years on this — apprenticing in Tijuana clinics, running the Global Ibogaine Therapy Alliance, and writing the field's first clinical safety guidelines. He's a Mexico-licensed psychologist. He holds the only active export license for iboga root and led the first Nagoya-compliant export out of Gabon, where he was initiated into two Bwiti traditions. His team co-authored the Stanford study in Nature Medicine on ibogaine and veteran traumatic brain injury. Ambio has now treated over 3,000 people. Most of what you think you know about ibogaine is probably wrong. It's not a high. It puts you flat on your back for twelve hours and asks for everything. It resets the body off opioids almost overnight. It seems to repair the brain in ways nobody fully understands yet — MS lesions shrinking, a guy walking in with a cane and leaving it behind.  We get into the cardiac risk, the deaths, the Trump executive order, and why the science and the ceremony might not survive being pulled apart. And we talk about the part nobody wants to hear: the medicine doesn't do the work for you.

Host Dave Asprey sits down with Chris Rinsch, co-founder and President of Timeline Longevity and a PhD cell biologist who has spent nearly two decades doing pharmaceutical quality clinical research on one of the most underrated longevity molecules on earth. Before founding Timeline in 2007, Rinsch worked in venture capital investing in pioneering life sciences companies and in biotechnology developing cell-based therapies at Swiss biotech company ISOTIS SA. He has authored original publications in Nature Medicine, Nature Metabolism, JAMA Open, and Cell Reports Medicine, and holds internationally filed and granted patents on urolithin A. This is the first time a Timeline co-founder has appeared on the show. Together, Dave and Chris break down the full science of urolithin A, the postbiotic compound unlocked from pomegranate by gut bacteria, and why it triggers mitophagy to clear out damaged mitochondria and replace them with high-functioning ones. They cover why only 30 to 40 percent of people can produce urolithin A from food alone, how one month of supplementation measurably improved immune cell populations in people aged 50 to 70, and why Dave has stacked this into his daily longevity protocol alongside NAD precursors and nootropics for years. If you are serious about biohacking your mitochondria, extending healthspan, and doing smarter not harder longevity work, this episode delivers the deep science to back it up. You'll Learn: Why urolithin A outperforms rapamycin in worm lifespan studies and rivals caloric restriction at 45 percent life extension How mitophagy works, why it declines with age, and why it is one of the most important anti-aging mechanisms in the body Why eating pomegranates or taking cheap pomegranate extract does not work for most people and what to take instead How one month of MitoPure improved natural killer cells, CD8 T naive cells, and reduced inflammation in adults aged 50 to 70 Why mitochondria are central to metabolism, brain optimization, immune function, cardiovascular health, and skin aging How Timeline's topical urolithin A produced statistically significant reductions in fine lines and wrinkles after eight weeks Why Dave considers this one of the most clinically validated supplements in his longevity stack alongside NAD and fasting protocols How L'Oreal became a Timeline investor after confirming the mitochondrial science was unlike anything in their existing ingredient library What the XPRIZE Healthspan competition is targeting and why Timeline is competing to reverse biological aging by 10 to 20 years Why the future of functional medicine will require a mitochondrial blood test and how close we are to having one Thank you to our sponsors! - EMR-Tek | https://www.emr-tek.com/DAVE and use code DAVE - Calroy | Go to Calroy.com/DAVE for exclusive discounts on Arterosil HP, Vascanox HP and all Calroy products. - Neuronic | Go to www.neuronic.online Code DAVE for $100 off - ENERGYbits | If you want a simpler, smarter way to support your body… this is it.

We've been talking about this with CEO Jake Leach for a while now – it will be a 50% smaller with what they're calling advanced sensing capabilities. According to Leach, G8 will adapt to the physiologic variability of each user. It has additional technology built in, based on a new silicon chip design and algorithm. 15 day wear is now the baseline for all Dexcom sensors moving forward. At launch the G8 will only measure glucose but the plan is for a multi-analyte version to follow. That would measure ketones and potassium. Ketones we know – but potassium is very important for people with kidney and possible for people taking some diabetes meds. It's an interesting space to watch.. btw, analyte is just a medical word for the specific thing you're measuring – the target of the test you're running. we're going to hear that word a lot I think..   Looks like an FDA submission for the G8 next year.. with an outside the US launch the following year. https://www.drugdeliverybusiness.com/dexcom-unveils-next-gen-g8-cgm/ XX Glucotrack has submitted its implantable continuous blood glucose monitor (CBGM) for FDA IDE, that's investigational device exemption and would enable the company to initiate a U.S. clinical study for the fully implantable technology. Rutherford, New Jersey-based Glucotrack's device features no on-body external component. The company aims to offer it for three years of continuous, accurate blood glucose monitoring for a more convenient, less intrusive solution. Unlike traditional CGMs that measure glucose in interstitial fluid, the CBGM measures glucose levels directly from the blood. The implant goes five centimeters within the subclavian vein. Glucotrack's active implantable device has a small battery and some electronics that go just under the skin in the pectoral region. The location of the implant is not in a major vessel, but the implant can measure real-time glucose levels as pulsatile blood flows over the tip of the sensor. https://www.drugdeliverybusiness.com/glucotrack-submits-long-term-implantable-cbgm-fda-ide/ XX PharmaSens today announced the publication of data from the first clinical study evaluating its all-in-one insulin patch pump offering. The all-in-one pump pairs the Niaa Essential insulin patch pump with the SynerG continuous glucose monitor (CGM) sensor developed by Pacific Diabetes Technologies. However, this system would be one device that features both the pump and CGM technology.   PharmaSens and SiBionics also have a collaboration aimed at developing the all-in-one solution. They are jointly developing the next-generation Niia insulin patch pump with a SiBionics CGM. PharmaSens expects a second feasibility study in the second quarter to evaluate the next-generation pump with SiBionics' CGM.   PharmaSens says the clinical feasibility study of Niia demonstrated for the first time ever that the combined offering is, in fact, feasible. It believes its device addresses the need for alternatives to multi-device diabetes management. systems.   Aggregated MARD for the investigational device came in at 11.6%. A MARD target of less than 10% is considered ideal for CGM devices, but PharmaSens said that, in the context of the early feasibility study, the results were encouraging and provide evidence supporting the development of an all-in-one system. https://www.drugdeliverybusiness.com/pharmasens-efs-insulin-patch-pump-cgm/ XX   XX ViCentra launches the newest version of the Kaleido pump system in Europe. This is that small colorful pump, with Diabeloops algorithm and the Dexcom G7. It'll be in Germany and the Netherlands later this summer. https://hellokaleido.com/vicentra-announces-commercial-launch-of-new-smartphone-controlled-kaleido-automated-insulin-delivery-patch-pump-system/--   XX Diabeloop just got CE Mark approval for DBLG2 integrations – it's latest AID platform the company has kicked off the gradual European launch of the technology. It currently offers DBLG2 as a smartphone application on Android, with iOS integration coming soon. As you just heard, it's integrated with kaleido and the company says it plans to make additional configuration for DBLG2 with alternative pumps "available soon." Running on a user's smartphone, DBLG2 works as a self-learning algorithm. It continuously analyzes glucose data, calculates insulin needs in real time and automatically adjusts delivery. https://www.drugdeliverybusiness.com/diabeloop-fda-next-gen-algorithm-g7/   XX Among adults with type 1 diabetes (T1D), the initiation of GLP-1-based therapy was associated with a lower risk for all-cause death, several cardiovascular outcomes, all-cause hospitalisations, and hypoglycaemia, without a higher risk for diabetic ketoacidosis.   METHODOLOGY: Researchers in Greece conducted a retrospective cohort study utilising real-world data from a global health research network to evaluate the association between GLP-1-based therapy and cardiovascular and renal outcomes in adults with T1D. A total of 4088 patients receiving GLP-1-based therapies (median age, 43 years; 34.3% men) were propensity score matched with an equal number of patients not receiving the treatment. The risk for hypoglycaemia was lower with GLP-1-based therapy (hazard ratio, 0.72; P = .021); however, the risk for diabetic ketoacidosis did not differ significantly between the two groups. https://www.medscape.com/viewarticle/glp-1-drugs-tied-cardiovascular-benefits-t1d-2026a1000fbx   XX Eli Lilly and Company (NYSE: LLY) today announced detailed results from two late-phase trials showing that people with obesity maintained their weight loss long term with either Foundayo or lower-dose Zepbound after switching from higher doses of injectable incretin therapy. The findings from SURMOUNT-MAINTAIN and ATTAIN-MAINTAIN, were presented at the 33rd European Congress on Obesity (ECO) and published in The Lancet and Nature Medicine, respectively.   "Weight regain remains one of the biggest challenges in obesity care, and is often the result of treatment interruptions that cause biology to work against patients, undoing the progress they've made," said Louis J. Aronne, M.D., FACP, DABOM, founder and Chair Emeritus of the American Board of Obesity Medicine, former president of The Obesity Society, Fellow of the American College of Physicians, world-renowned obesity specialist and Lilly consultant. "These medicines can be used for long-term maintenance today, and results from SURMOUNT-MAINTAIN and ATTAIN-MAINTAIN provide additional evidence of their potential when switching from higher doses of injectable incretin therapy." https://investor.lilly.com/news-releases/news-release-details/lillys-foundayo-and-lower-dose-zepbound-helped-people-maintain XX Scientists in Sweden have developed a more reliable way to create insulin-producing cells from human stem cells. These lab-grown cells not only respond strongly to glucose but were also able to restore blood sugar control when transplanted into diabetic mice. When transplanted into diabetic mice, the cells gradually restored the animals' ability to regulate blood sugar. Long way to go, as we say with most of these mice studies. https://www.sciencedaily.com/releases/2026/05/260505234620.htm XX Interesting look at how the body controls sugar storage – apparently this finding challenges long-standing biology concepts and could open new directions for disease treatment. Published in Nature, the study describes a potential method for directly reducing glycogen, the stored form of sugar in the body. These scientists discovered that glycogen can be directly regulated by ubiquitin, a protein best known for marking damaged proteins for recycling or removal. The study is the first to show that ubiquitin can regulate glycogen in humans, overturning more than 50 years of scientific understanding. Excess glycogen is also associated with more common health problems, including diabetes, obesity, liver disease, and heart disease.       https://scitechdaily.com/scientists-just-rewrote-biology-hidden-mechanism-could-transform-diabetes-treatment/ XX A new Oklahoma law will give parents the option to have their children screened for Type 1 Diabetes.   The measure passed with overwhelming bipartisan support in the Legislature and takes effect Nov 1. Oklahoma consistently ranks among the states with the highest rates of diabetes and diabetes-related deaths. The law gives parents access to antibody testing that can detect risk years before symptoms develop, helping families take preventive action and avoid emergency room visits. https://journalrecord.com/2026/05/11/oklahoma-law-expands-access-type-1-diabetes-screening/ XX More to come including a new study trying to figure out why some people are more likely to develop diabetes, a look at cannabis and preventing metabolic disorders, and XX   A National Institutes of Health (NIH)-funded study has identified key differences in human pancreatic islet cells that may help explain why some people are more likely to develop diabetes. Researchers found that the mix of hormone-producing cells in the pancreas varies widely from person to person, and that variation plays a central role in how the body regulates blood sugar. The study involved a deep dive into islet cell function that is linked to donor traits associated with observable characteristics, or phenotype, such as sex, race and ethnicity, as well as genetic information, or genotype, including predicted ancestry and genetic risk for both type 1 and type 2 diabetes. The findings highlight that islet cell composition, rather than the physical size and shape of islets, is a key factor in regulating hormone release. The team found that the makeup of pancreatic islets plays a major role in how effectively they release insulin and glucagon — key hormones that regulate blood glucose. Islets with a higher proportion of insulin-producing beta cells showed stronger insulin secretion in response to various stimuli, while higher levels of alpha and delta cells were generally linked to reduced insulin output. In addition, the researchers found that islet hormone secretion is affected by donor traits, such as sex, race and ethnicity and their genetic makeup, including ancestry predicted from genetic testing and genetic risk for type 2 diabetes. Combined, the findings of the study have significant implications for understanding the factors that may predispose people to diabetes. "This study is the tip of the iceberg," said Dr. Evans-Molina. "We hope this dataset becomes useful to the entire diabetes research community and that researchers use it to answer questions about the genotype-phenotype correlation within these data."   https://www.nih.gov/news-events/news-releases/nih-funded-study-maps-human-pancreatic-islet-cells-offering-new-clues-diabetes-risk XX XX XX Research published recently in JAMA Network Open offers illuminating evidence suggesting there is a positive association between GLP-1 agonists—drugs commonly used to treat obesity and diabetes—and better outcomes among breast cancer patients.   "This study suggests that GLP-1 drugs may offer protective benefits potentially improving survival and recurrence risk in some female patients with breast cancer – whether this is related to weight control, improve cardiovascular health or other mechanisms remains to be studied," said study senior author Bernard F. Fuemmeler, Ph.D., MPH, associate director for population sciences and the Gordon D. Ginder, M.D., Chair in Cancer Research at VCU Massey Comprehensive Cancer Center.   Breast cancer patients who are also obese or have type 2 diabetes experience more aggressive cancer growth and worse outcomes. Prior studies have shown that weight loss treatment and surgery following a breast cancer diagnosis are associated with improved heart health and increased survival.   What are GLP-1 drugs? Glucagon-like peptide-1 receptor agonists (GLP-1 RAs). Approved to treat type 2 diabetes in 2005 and weight management in 2021. Impacts on breast cancer survival and recurrence are still unclear. Since 2020, the use of these drugs has increased dramatically, where approximately 12% of Americans have used GLP-1s for weight loss, according to a RAND report.   The research findings Through a retrospective cohort study examining the electronic health records of more than 840,000 breast cancer patients who were diagnosed between 2006 and 2023, the results suggest there is a potential link between GLP-1 RAs and improved outcomes among breast cancer patients who are also obese or have type 2 diabetes.   GLP-1 RA use was associated with an overall lower risk of death from any cause over a 10-year follow-up period among breast cancer patients. Additionally, breast cancer survivors who used GLP1-RAs for diabetes or obesity had a significantly lower risk of their cancer returning over 10 years following their initial treatment.   "Our findings align with emerging preclinical research and contribute to a growing body of literature related to GLP-1 RA use in oncology settings," said study lead author Kristina L. Tatum, PsyD, MS, of the VCU School of Public Health.   What's next? Further studies are needed to understand the biological mechanisms, if any, between GLP-1 RAs and breast cancer outcomes. The research team intends to further evaluate these correlations through randomized clinical trials.   "Our study underscores the potential of GLP-1 RAs as an adjunct strategy for improving cancer-related outcomes among patients with breast cancer, although clinical trials are needed to inform effective therapeutic approaches and clinical decision making," Fuemmeler said. https://www.oncology-central.com/could-glp-1-receptor-agonists-improve-outcomes-for-breast-cancer-patients-with-obesity-or-with-type-2-diabetes/ XX Researchers at UC Riverside gave cannabis to obese mice and found that not only did the rodents lose weight, but when given a concentrated cannabis oil, the mice also saw striking benefits in their metabolic function. DiPatrizio said his team studied the issue to better understand why cannabis users show significant reductions in weight and risk for diabetes compared with nonusers. "We would think that chronic cannabis users would be eating more and weigh more, but it's just the opposite," DiPatrizio said. Scientists are increasingly examining the possibility that cannabis compounds could fight obesity or metabolic disorders like diabetes. Cannabinoids interact with the body's endocannabinoid system, which partially controls nearly every aspect of our physiology, including metabolism and appetite. That creates the possibility that targeting this widespread system could unlock new therapies for these conditions. https://www.sfgate.com/cannabis/article/cannabis-weight-loss-california-study-22255328.php XX A new campaign launched by diaTribe and Genentech aims to empower and educate people about diabetes-related eye disease. Here's what you can do today to protect your eye health. To help address these barriers, diaTribe and Genentech partnered to launch All Eyes on DME, a new campaign that aims to spread awareness and educate people at-risk for or living with diabetes-related eye conditions like DME. Also partnering in the campaign is actor and comedian Damon Wayans, who wanted to share his journey (and, of course, a joke or two) with type 2 diabetes to open up the conversation about what is often a stigmatized or less talked about topic: eye health and diabetes.   One of these important conversations happened recently at the All Eyes on DME launch in New York City, where Wayans joined a panel of experts, advocates, and people living with DME to talk about diabetes-related eye disease and how to help prevent it. https://www.alleyesondme.com/dme-in-the-spotlight.html https://diatribe.org/diabetes-complications/all-eyes-dme-new-campaign-spotlights-eye-health-and-diabetes

In this week's episode of the Xtalks Life Science Podcast, host Ayesha Rashid, Senior Life Science Journalist at Xtalks, spoke with Alessio Travaglia, PhD, Neuroscientist and Director of Translational Science at the Foundation for the National Institutes of Health (FNIH). New findings from a study published in Nature Medicine suggest that a single blood test may be able to predict the onset of Alzheimer's symptoms within a three- to four-year period. Dr. Travaglia discusses how the test works, what it reveals about the earliest stages of disease and why identifying patients before symptoms appear could transform clinical trials and therapeutic development. Dr. Travaglia has 15 years of experience in basic and translational neuroscience in academia, non-profit, management consulting and venture philanthropy. Tune in to learn more about the new test and how it could transform the early detection of Alzheimer's disease.

In this episode, I explore where AI can genuinely help with health questions, where it can fall dangerously short, and how to use it more wisely before trusting it with decisions that really matter.AI tools like ChatGPT, Claude, Grok, and Gemini can be useful for understanding lab results, summarizing a doctor's visit, preparing questions before an appointment, or making sense of complicated medical language. But when people ask AI, “What's wrong with me?” or “Should I go to the hospital?” the answer can depend heavily on whether the user provides enough clinical context.I tested this myself with two invented scenarios: hand pain and a concerning headache. In both cases, the AI gave general guidance but failed to ask key questions a physician would naturally ask, such as my age, whether symptoms came on suddenly, whether I had experienced this before, or whether there was relevant family history. When I explicitly asked the AI to interview me first, the answers improved dramatically.Research supports that concern. A recent Nature Medicine study found that when real users interacted with AI about clinical scenarios, the AI gave the correct triage recommendation in only about 43% of cases and often underestimated urgency. The problem was not always that AI lacked medical knowledge. It was that users often did not provide enough information, and the AI did not reliably ask for what it needed.Another Nature Medicine study tested ChatGPT Health using complete clinical vignettes. Even with all the information provided, the AI struggled with the most urgent and least urgent cases. It sometimes recognized serious diagnoses but recommended delayed care when immediate emergency care was appropriate. That suggests the issue is not just knowledge, but judgment.AI does perform better in lower-risk, supportive roles. It can translate medical jargon into plain language, explain abnormal lab results, organize a visit summary, and help patients prepare better questions for their doctor. Recording a medical visit with the doctor's permission and then using AI to create a personal summary can be especially helpful, though AI-generated clinical notes still need careful physician review.The most practical strategy is simple: before asking AI for health guidance, tell it, “Before you respond, please ask me all the questions you need to give me accurate information about my situation.” This does not make AI a doctor, but it can make the interaction more useful and less incomplete.Takeaways: AI can be helpful for understanding, organizing, and preparing for healthcare conversations, especially when the stakes are relatively low. AI is not yet reliable enough to determine whether symptoms are urgent or whether you should go to the ER. When using AI for health questions, ask it to interview you first, and when symptoms feel serious, unusual, sudden, or frightening, do not rely on AI as your final decision-maker.Send us Fan Mail

Most people think their kitchen is the safest place in their home. The truth is the opposite. The cookware you use every day, the cutting boards you trust, the utensils you stir with, even the coffee maker on your counter, may be quietly leaching forever chemicals, microplastics, and heavy metals into your food and into your brain. In this episode, I sit down with Jordan Nathan, founder and CEO of Caraway, the brand redefining what nontoxic actually means in the modern home. Jordan walks me through the night he called poison control after overheating a Teflon pan, the 2-year journey to launch a cookware line free of PFAS, and why six U.S. states have now banned forever chemicals in cookware. We unpack what PFAS, PFOA, and PTFE actually are, why they accumulate in fat tissue and cross the blood brain barrier, and why scratched pans, plastic cutting boards, and black nylon utensils are some of the most dangerous things in your kitchen. Then we go deep on the science. I break down the Nature Medicine 2025 study showing microplastics in human brain tissue at higher concentrations than the liver or kidney, with the highest accumulation found in dementia brains. We cover the rise of autoimmune disease, the credit card's worth of plastic the average person consumes every week, Caraway's third party testing for over 600 PFAS chemicals, and a full kitchen audit on a $1,000 budget covering induction vs gas, dishwasher dangers, and what's coming next as Caraway expands into the broader nontoxic home. This conversation will completely change how you think about what is in your kitchen, what is in your body, and what you can actually do about it.

Dietitian Nutritionist Leyla Muedin discusses a Stanford-led randomized controlled trial published in Nature Medicine in which a five-day, calorie-restricted fasting-mimicking diet improved symptoms and inflammatory markers in people with mild to moderate Crohn's disease. In the three-month study of 97 patients, 65 followed monthly five-day cycles of 700–1100 calories/day with plant-based meals, while 32 continued usual diets; about two-thirds of the fasting-mimicking group reported symptom improvement, with fatigue and headaches but no serious side effects, and fecal calprotectin and other inflammatory molecules decreased. She notes bowel rest and the specific carbohydrate diet as additional approaches. The episode also explains how antibiotics can cause diarrhea by disrupting gut bacteria, lists higher-risk antibiotics, offers supportive steps (hydration, BRAT foods, avoiding irritants), recommends Saccharomyces boulardii taken away from antibiotics, and outlines warning signs requiring medical care, including possible C. difficile.

Send us Fan MailIt's a rare piece of good news. A single-dose dengue vaccine developed in Brazil as part of an international collaboration protected people against at least two strains of the virus for five years or longer, and did so safely. The vaccine was already being tested across Brazil and the findings helped boost confidence in its use. “This is a big deal,” says Dr. Andre Siqueira, Head of the Dengue Global Program at the Drugs for Neglected Diseases Initiative (DNDI).  Dr. Siqueira, who is also an Infectious Diseases Consultant at Brazil's Instituto Nacional de Infectologia Evandro Chagas, a hospital that is part of the Oswaldo Cruz Foundation (Fiocruz), helped develop the vaccine. He chatted with One World, One Health about the work in 2024. The new vaccine worked almost perfectly to keep people from being hospitalized with severe dengue symptoms, Dr. Siqueira and the team reported in Nature Medicine.  That's a big deal. Dengue can cause terrible symptoms, including severe abdominal pain, internal bleeding, severe muscle aches, and long term fatigue. From January 2025 to January 2026, dengue killed more than 4,000 people. The only other dengue vaccines currently available are a two-dose formula made by Japanese manufacturer Takeda and Sanofi's Dengvaxia, which the company is discontinuing because of a lack of demand. In this episode, Siqueira updates host Maggie Fox about the latest findings on the new vaccine's efficacy and its rollout in Brazil.

A recent study published in Nature Medicine claims a blood test can predict when you'll develop Alzheimer's disease, and it got a lot of attention. But how well does it actually work, and should you rush out and get tested? In this episode, we break down the study behind the headlines to understand what it really shows, where the major limitations lie, and what it means for anyone thinking about getting this kind of test. Topics and Questions Covered What P-Tau 217 is and why it's become the leading blood-based biomarker in Alzheimer's research. How researchers built a predictive "clock" from blood test data and what that process required. The important distinction between having pathology in your brain and actually developing dementia. Who should and should not be getting tested. What a large Norwegian population study reveals about the overlap between pathology and normal cognitive function. How biomarkers like this might eventually fit into a broader, more personalized approach to prevention. and more! -------------- To submit a question for us to answer on the podcast, go to brainjo.academy/question.

Shahad Abdulsahib discusses a phase 1 clinical trial of intracerebroventricular bivalent EGFR and IL13Rα2 CAR T cells for recurrent glioblastoma, published in Nature Medicine.

A randomized trial in the New England Journal of Medicine found prehospital whole blood transfusion did not improve 30-day mortality over standard component therapy in traumatic hemorrhage, supporting current transfusion protocols. A large population-based study showed patients with positive fecal occult blood tests who did not complete follow-up colonoscopy had significantly higher colorectal cancer incidence and more advanced-stage disease. Finally, a study in Nature Medicine of nearly 15,000 individuals found antibiotic exposure reduced gut microbial diversity for up to 4–8 years, with clindamycin and fluoroquinolones causing the most persistent disruption.

Join us in this episode for a conversation with Aaron Phillips, PhD, scientist and Associate Dean of the Medical School at the University of Calgary. In this conversation we discuss two papers, A neuronal architecture underlying autonomic dysreflexia published in the journal Nature, and An implantable system to restore hemodynamic stability after spinal cord injury published in the journal Nature Medicine. In these papers Dr. Phillips and his team first identify specific neuronal components, and their location, responsible for blood pressure increases due to autonomic dysreflexia. Then an implantable device is demonstrated to help control, via neuromodulation, blood pressure fluctuations in both pre-clinical models and people living with SCI. We invite you to listen in as Dr. Phillips outlines this tour de force in neurologically understanding, and intervening on, hemodynamic instability after SCI.

Welcome to Pulse: Amplify, where we sit down with the leaders and changemakers shaping the future of health. A recent Nature Medicine study went viral after reporting that ChatGPT Health under-triaged more than half of emergency cases when tested using clinician-written scenarios. The finding raised serious concerns about whether consumer AI tools are safe for medical triage.But researchers from Macquarie University's Australian Institute of Health Innovation took a closer look at the study design and suspected the results might reflect the evaluation format rather than the AI's clinical capability.In this episode of Pulse Amplify, Louise and George speak with David Fraile Navarro about their follow-up study testing five frontier AI models across more than a thousand trials. Their research suggests that when AI systems are evaluated using more natural, patient-style interactions rather than exam-style prompts, triage performance improves significantly.The discussion explores why prompt structure, forced answer formats, and restrictions on clarifying questions can dramatically alter model behaviour, and why designing realistic evaluation methods is essential as millions of people begin using AI for health advice.The conversation also examines broader questions: How should AI triage tools be evaluated? What role should clinicians play in AI-mediated care? And what do patients need to know before trusting AI with health decisions?ReferencesRamaswamy A. et al.

A structural shift is occurring in the managed IT services landscape as AI capabilities are rapidly embedded across enterprise applications, with oversight and risk management functions increasingly separated out and monetized as add-on services. Vendors, including Microsoft and OpenAI, are deploying AI agents in essential tools such as Outlook, Teams, and Excel, then selling governance, security, and compliance capabilities as additional paid layers. The core mechanism is the transfer of operational and liability risk downstream to IT service providers and their clients, while ownership of the control plane and margin on risk mitigation remain with the vendors. The episode highlights consequential findings regarding AI reliability and adoption. A Nature Medicine study found that OpenAI's ChatGPT Health underestimated emergency severity in 51.6% of cases, prompting concerns about overreliance on AI for critical decisions. Additionally, Confluent's UK executive survey indicated that 62% of organizations are already shifting decision-making to AI, but only 7% have a company-wide AI strategy, and fewer than half of executives and employees agree on actual daily AI usage. Most leaders receive little formal AI training yet are second-guessing their own judgment in favor of AI output. Further reinforcing the governance gap, Microsoft is launching Agent 365 and new enterprise security tiers, while OpenAI's acquisition of Promptfoo signals a focus on AI reliability testing and compliance monitoring. Funding for GRC platforms like IntelliGRC demonstrates capital flowing into third-party oversight solutions. The recurring pattern is vendors first pushing broad agent adoption, then introducing and monetizing governance as a discrete add-on, often outside the default package. Operationally, MSPs and IT leaders face increased liability exposure if they rely on vendor-native governance without independent audit or measurement capability. The absence of industry-standard reliability metrics for AI, combined with the perception and usage gaps inside organizations, calls for MSPs to lead in auditing, documenting, and independently measuring AI usage and performance. Failing to proactively manage these controls can result in silent risk absorption and unfavorable positioning as vendors bundle compliance and pass residual risk downstream to service providers.

A new study shows OpenAI's chatbot called ChatGPT Health is underestimating the seriousness of certain medical emergencies. For the study published in the journal Nature Medicine, ChatGPT Health was given 60 medical situations, and the responses were compared to the responses of three doctors. Researchers concluded that a little over half of emergency cases, ChatGPT recommended seeing a doctor within 48 hours in contrast to the opinion of doctors saying ChatGPT Health should have advised the emergency room instead. We talked about this with Dr. Fred Browne of Griffin Health.Image Credit: Dr. Fred Browne / Griffin Health

Lo han conseguido de un dibujo que él tocó hace cinco siglos. Y lo que ese ADN puede y no puede decirnos sobre el genio es igual de fascinante que la historia de cómo lo encontraron. Tu sueño como oráculo — SleepFM, un modelo de inteligencia artificial publicado en Nature Medicine, analiza cómo duermes y predice diabetes, hipertensión, depresión o problemas cardiovasculares años antes de que aparezca ningún síntoma. El tercio de vida que dabas por perdido para la medicina resulta ser la ventana más rica que tenemos sobre nuestra salud futura. ⚡ El cerebro al borde del caos — La neurociencia moderna propone que tus 86.000 millones de neuronas operan permanentemente en el límite entre el orden y el desorden. Y que es precisamente esa inestabilidad controlada la que genera la inteligencia, la conciencia y la capacidad de adaptarte al mundo. La física de los montones de arena aplicada a la mente humana. Tus órganos tienen edades distintas — Dos equipos científicos independientes, usando tecnologías distintas, llegan a la misma conclusión: tu corazón puede tener biológicamente 62 años mientras tu cerebro tiene 45.

Highlighting the struggles faced by the 225 million individuals worldwide known as "Covid long haulers," Dr. Kristin shares her expertise on the often debilitating neurological symptoms that persist in many patients well after recovery from the initial infection. Throughout the episode, Dr. Kristin explores the science behind COVID-19's effects on the brain, emphasizing the structural impact of the virus's spike proteins and their lingering presence. By referencing several studies, including those published in top-tier journals such as Molecular Neurobiology and Nature Medicine, she discusses the immune-mediated pathways that lead to neuroinflammation, cognitive deficits, and reduced gray matter in COVID-19 patients. She sheds light on the necessity for personalized protocols when treating long-haul symptoms, combined with the use of low-level lasers, supplements, and lifestyle changes to promote healing and brain health. Key Takeaways: COVID-19 can have long-term neurological effects, leading to symptoms such as brain fog, memory loss, and anxiety. Spike proteins from the virus remain in the body, contributing to neuroinflammation and facilitating long-term cognitive issues. Integral therapeutic approaches include tailored supplementation, regular exercise, low-level laser therapy, and controlled doses of methylene blue. Variability in patient responses necessitates highly individualized treatment plans to manage and potentially reverse symptoms. Maintaining brain health requires attention to exercise, nutrition, and supplementation to combat the inflammatory effects of the virus. Notable Quotes: "Both long Covid and COVID vaccine can sometimes create things like brain fog, neuroinflammation, and long term sequelae." "We have more abnormal than normal brains in the world." "The COVID spike proteins, they hang out at the base of the skull, throughout the skull, in a system called the duromeningeal system." "COVID long haulers have way too much inflammation. Low-level laser can help you with that." "For every nerve that goes from the brain to the stomach, nine go back up."

What if we could take the guesswork out of cancer treatment—and move from try and hope to test and know? In this episode of Med Tech Gurus, we sit down with Jim Foote, CEO and Founder of First Ascent Biomedical, whose mission began after losing his son to cancer. That experience became the driving force behind Functional Precision Medicine (FPM)—a groundbreaking approach that combines tumor testing, genomics, and AI to rank the most effective drugs for each patient in just ten days Backed by a Nature Medicine study showing an 83% patient benefit rate, First Ascent is proving that personalization saves lives. With automation reducing lab times from hours to minutes and new CLIA-certified labs accelerating access, Jim and his team are reshaping how cancer care is delivered. From building trust with clinicians to leading through loss, Jim shares a powerful story of innovation, resilience, and purpose that every medtech leader can learn from.

The vagus nerve, also known as the Great Nerve, connects the brain to all parts of the body, like an internet (Figure below). Every week we're learning more about its importance for health and disease. Until recent years the brain and immune system were thought to be in separate “firewalled” compartments. But that turned out to be far from the truth.Dr. Kevin Tracey, who directs the Feinstein Institute at Northwell Health, has been studying the vagus nerve for more than 3 decades. In the early 1990's he made the seminal observation that stimulating the vagus reduces the inflammatory cytokine known as tumor necrosis factor (TNF), what he described at the time as a “holy s**t” moment. In 2025 he published the book THE GREAT NERVE with many rich patient anecdotes and the history for how this field developed.I wrote about the brain-immune axis previously on Ground Truths, spotlighting the vagus nerve's role. That included much more on depth of the pathways if you are interested.We discussed the recent FDA July approval for refractory rheumatoid arthritis (RA)(unresponsive to medications or intolerance to medical therapy) based on a sham-controlled randomized trial published in December 2025 in Nature Medicine. It is striking that the benefits were derived from 1 minute of vagal stimulation per day. That stimulation is barely perceived (tingling, many not at all) by device recipients. The surgery takes one hour to implant the tiny stimulator device along side the vagus nerve in the neck. But this is much bigger than a treatment for RA. It is now being tested for lupus, Crohn's disease, and other autoimmune conditions. That's beyond the role vagus nerve stimulation (VNS) has played for epilepsy and depression, independent of VNS's anti-inflammatory impact (Tracey named it “the inflammatory reflex”).We also discussed handheld VNS devices, potential use for Long Covid and POTS, cold plunges, heart rate variability, stress, and other topics related to the vagus nerve and parasympathetic nervous system (the brakes, “rest and digest” as opposed to the sympathetic nervous system (the gas, “fight or flight”).Most people are not aware of this device approved treatment for an autoimmune disease. Our treatments are so drug-centric but they are immunosuppressive, have important side-effects, and are expensive. It's good to see a non-drug approach get compelling data as an alternative. Moreover, as I recently wrote about, there's a shift ongoing from treatment to cures vs autoimmune diseases that will be adding to the mix.Here are some very recent papers about the vagus nerve to give you a sense about how its prominence is getting appreciated more all the timeGut-brain-vagus axis for reward circuit and addiction, 30 Jan 2026, Science AdvancesRandomized trial of VNS for depression , Int J of Neuropsychopharm 2026 The vagus nerve role in heart function after a heart attack, Cell, February 2026Vagus receptors and hemorrhage, blood volume, Nature, 28 Jan 2026A Quick PollThank you Harshi Peiris, Ph.D., Tay MacIntyre, David Dansereau, MSPT, Max Manwaring-Mueller, RJ, and over 600 others for tuning into my live video with Kevin J.

La maladie d'Alzheimer touche davantage les femmes que les hommes. Aujourd'hui, près de deux tiers des personnes atteintes sont des femmes. Longtemps, cette différence a été expliquée presque uniquement par un facteur simple : les femmes vivent plus longtemps. Or, les recherches récentes montrent que cette explication est insuffisante. Même à âge égal, les femmes présentent un risque plus élevé de développer la maladie.Une étude de référence publiée dans la revue scientifique Nature Medicine montre que le cerveau féminin vieillit différemment face aux mécanismes d'Alzheimer. Les chercheurs ont mis en évidence des différences biologiques profondes, notamment dans la manière dont les protéines toxiques associées à la maladie s'accumulent et se propagent.Le premier facteur clé est hormonal. Les œstrogènes, hormones sexuelles féminines, jouent un rôle protecteur pour le cerveau. Elles favorisent la plasticité neuronale, soutiennent la mémoire et aident à réguler l'utilisation du glucose par les cellules cérébrales. Or, lors de la ménopause, les niveaux d'œstrogènes chutent brutalement. Cette transition hormonale pourrait rendre le cerveau plus vulnérable aux lésions liées à Alzheimer, en particulier si elle survient précocement ou sans compensation hormonale.Le deuxième facteur est génétique. Le principal gène de risque connu pour Alzheimer, appelé APOE ε4, n'a pas le même impact selon le sexe. Plusieurs études montrent que les femmes porteuses de ce gène présentent un risque plus élevé que les hommes porteurs du même variant. Autrement dit, à patrimoine génétique égal, le cerveau féminin semble plus sensible aux mécanismes pathologiques de la maladie.Troisièmement, le métabolisme cérébral diffère entre les sexes. Les études d'imagerie montrent que, chez les femmes, certaines régions du cerveau impliquées dans la mémoire consomment l'énergie différemment au cours du vieillissement. Cette adaptation, efficace plus jeune, pourrait devenir un point de fragilité avec l'âge.Enfin, des facteurs sociaux entrent aussi en jeu. Les femmes âgées aujourd'hui ont souvent eu, dans leur jeunesse, un accès plus limité à l'éducation ou à des carrières intellectuellement stimulantes. Cela peut réduire la « réserve cognitive », c'est-à-dire la capacité du cerveau à compenser les lésions avant l'apparition des symptômes.En résumé, si les femmes sont plus touchées par Alzheimer, ce n'est pas seulement parce qu'elles vivent plus longtemps. C'est le résultat d'une combinaison de facteurs hormonaux, génétiques, métaboliques et sociaux. Comprendre ces différences est essentiel pour développer, à l'avenir, des stratégies de prévention et de traitement mieux adaptées aux femmes comme aux hommes. Hébergé par Acast.

In this episode of Let's Talk Micro, we break down metagenomic next-generation sequencing (mNGS) and how it's changing the way we diagnose complex infectious diseases. I'm joined by Steve Miller, MD, PhD—Chief Medical Officer at Delve Bio—to discuss how unbiased metagenomics moved from research labs into real-world clinical practice. We cover what metagenomics is, how it differs from targeted PCR and sequencing, and where it adds the most value—especially in meningitis and encephalitis, immunocompromised patients, and cases where routine testing comes back negative. Dr. Miller shares insights from years of clinical experience, including how mNGS can improve diagnostic yield, shorten time to diagnosis, guide targeted therapy, and reduce unnecessary testing and hospital stays. We also touch on challenges like cost, result interpretation, diagnostic stewardship, and where metagenomics is headed next—including its role in public health and emerging infections.    Links & Resources Clinical metagenomics for meningitis and encephalitis (Nature Medicine) https://www.nature.com/articles/s41591-024-03275-1    Stay connected with Let's Talk Micro: Website: letstalkmicro.com Questions or feedback?

10,000 – that's the magic number of steps often recommended for a healthy lifestyle. With recent research looking into whether that number is an accurate benchmark for health, could the number of steps taken per day have an impact on brain health and, specifically, cognitive decline? That's precisely what a new study from Harvard Medical School and Mass General Brigham sought to examine, looking at how physical activity, specifically step count, impacted cognitive decline for those living with Alzheimer's disease. Dr. Bri Breidenbach and Sarah Lose join the podcast to break down the results of this new study, as well as share what current research says about the effect of other kinds of physical activity, such as different intensity exercises, on the brain and Alzheimer's progression.

Send us a textSummary: Microplastics are showing up in our water, food, air—and in human tissues. In this episode, I unpack what the best studies actually show (and don't), why risk is plausible but not proven, and the realistic steps you can take today without panic. In this episode, I cover:What microplastics are and why they're everywhere—from packaging and clothing to tire dust—and why production is still projected to rise ~70% by 2040 (OECD). OECD+2OECD+2The signal that caught my attention: patients with microplastics in carotid artery plaque had a markedly higher 3-year risk of heart attack, stroke, or death (NEJM). Association, not proof—but concerning. The Guardian+3New England Journal of Medicine+3PubMed+3What's turning up in the brain: autopsy work suggests rising microplastic loads in brain tissue, though causality remains unknown (Nature Medicine coverage). Nature+2Nature+2Everyday exposure: a liter of bottled water can contain ~240,000 plastic particles—mostly nanoplastics—using newer detection methods (NIH Research Matters). TIME+3National Institutes of Health (NIH)+3NCBI+3Indoor vs. outdoor air: estimates suggest we inhale tens of thousands of microplastic particles daily, with higher indoor concentrations (PLOS One). PLOS+1My takeaways for you (progress, not perfection):Respect the signal without catastrophizing. Human data are early, but cardiovascular and neurologic signals merit attention. New England Journal of Medicine+1Make the easy swaps: store food in glass, don't microwave plastic, favor loose-leaf tea over plastic-based tea bags, and replace plastic cutting boards with wood or glass. (These trim exposure; they don't eliminate it.) Air matters: consider a HEPA purifier for main living/sleeping areas and vacuum regularly; natural-fiber clothing sheds fewer synthetic particles. Water choices: where safe, use tap water with a quality home filter and a reusable (non-plastic) bottle—especially given the nanoplastic findings in some bottled waters.

Christmas is a time of celebration, when friends and family gather to enjoy meals together. However, many of us overindulge, which leaves us feeling tired, bloated, and guilty. What actually happens to our bodies when we overeat, drink more, and swap fibre for sugar? And is there a way to enjoy the season's pleasures without starting January full of regret? In this episode, ZOE's Head Nutritionist, Dr Federica Amati, joins Jonathan to explore how festive food traditions shape our health and how to navigate them without guilt or restriction. Dr Federica shares practical suggestions for gut-friendly food swaps, festive traditions worth reviving, and the one ingredient she always includes on her own Christmas table. This episode is full of helpful advice on how to care for your body in a season that often asks us to do the opposite. Unwrap the truth about your food

Plastic is everywhere. In our homes, on our streets, in our oceans. But recent research suggests it's also inside us: in our blood, our organs, even our brain. So how concerned should we be? Today, Jonathan and Dr. Federica Amati are joined by longevity doctor and clinician Dr. Sabine Donnai to explore one critical question: what does plastic exposure mean for our long-term health?  Dr. Donnai breaks down how microplastics travel from packaging, food, and air into our bloodstream, and why their size means they may cross biological barriers once thought impenetrable, including the blood-brain barrier. The conversation also looks at the broader health implications of plastic-associated chemicals like BPA, their potential links to hormone disruption, inflammation, and cardiovascular risk, and why avoiding them may be especially important for those living in urban areas. For listeners keen to take practical steps, this episode offers simple and empowering guidance. Dr. Donnai shares specific tools that can reduce your exposure without creating unnecessary fear or overwhelm. You'll also hear how diet plays a key role in supporting your body's natural detox processes and why a colourful, fibre-rich diet may help us all manage the modern plastic burden. If plastics are entering your brain and bloodstream, what does it mean for your future health? And how much control do we really have in a world built on plastic? Unwrap the truth about your food

On March 29, 2023, we released an episode titled, “The 4 PCOS Phenotypes”. That was in 2023! Now, on 29 October 2025, in the journal Nature Medicine, researchers have published, “Data-driven (FOUR) subtypes of polycystic ovary syndrome and their association with clinical outcomes”. PCOS is not ONE condition: is a constellation of metabolic, endocrine, and ovulatory dysregulation. We covered these 4 phenotypes back then. Is this what the “new data” found? Or what it something else? And how does these affect IVF or pregnancy outcomes? Listen in for details!1. Gao, X., Zhao, S., Du, Y. et al.

Inflammation is the body's natural way of healing, but when it becomes chronic and hidden, it quietly drives many of today's most common health problems—heart disease, diabetes, dementia, cancer, autoimmune conditions, and more. Unlike the redness and swelling from a cut or sprain, this “silent inflammation” often goes unnoticed while slowly damaging tissues and speeding up aging. Modern life fuels the fire: processed foods, food additives, pollution, plastics, chronic stress, too much sitting, and poor sleep. The good news is inflammation can be calmed by simple daily choices—eating colorful whole foods like berries, leafy greens, beans, nuts, seeds, and omega-3 rich fish; adding herbs and spices like turmeric and cumin; moving regularly; practicing relaxation; and repairing gut health. Even small shifts, like climbing stairs, eating within a shorter window, or reducing sugar, can make a big difference. By lowering inflammation, the body finds balance again, opening the door to more energy, resilience, and healthy aging. In this episode, I discuss, along with Dr. Shilpa Ravella and Dr. David Furman, why it's important to be aware of systemic inflammation and how to address it. Dr. Ravella is a gastroenterologist and Assistant Professor of Medicine at Columbia University Medical Center. She is the author of A Silent Fire: The Story of Inflammation, Diet & Disease, which investigates inflammation—the hidden force at the heart of modern disease. Her writing has appeared in The Atlantic, New York Magazine, The Wall Street Journal, TIME, Slate, Discover, and USA Today, among other publications.  Dr. David Furman is Associate Professor and Director of the Bioinformatics Core at the Buck Institute for Research on Aging, as well as the Director of the Stanford 1000 Immunomes Project. He obtained his doctoral degree in immunology from the School of Medicine, University of Buenos Aires, Argentina, for his work on cancer immune-surveillance. During his postdoctoral training at the Stanford School of Medicine, Dr. Furman focused on the application of advanced analytics to study the aging of the immune system in humans. He has published nearly thirty scientific articles in top-tier journals such as Cell, Nature Medicine, PNAS, The Lancet, and others.  This episode is brought to you by BIOptimizers.
