The Human Upgrade: Biohacking for Longevity & Performance

Scientists Test Carbon Dioxide Exposure To Help Clear Alzheimer's-Related Proteins From The Brain
Researchers at the University of New Mexico are investigating whether intermittent exposure to carbon dioxide-enriched air can stimulate the brain's glymphatic waste-clearance system and increase the movement of proteins associated with Alzheimer's disease into the bloodstream. In a preliminary human experiment involving 12 participants, alternating between ordinary air and air containing 5% CO2 for approximately 30 minutes produced rhythmic changes in cerebral blood vessels, followed by temporary increases in blood levels of amyloid-beta. Participants with signs of cognitive decline also showed a tau-related response. The findings, reported in July 2026, build on a 2025 study published in npj Parkinson's Disease demonstrating that intermittent carbon dioxide exposure stimulated cerebrospinal fluid movement and increased circulating levels of several neurodegeneration-related proteins. Although these results suggest a potential method for influencing brain waste transport, they do not establish that Alzheimer's plaques were removed or cognitive function improved. Host Dave Asprey explores carbon dioxide signaling, vasomotion, cerebral blood flow, glymphatic clearance, and the relationship between deep sleep and brain detoxification, examining whether controlled vascular stimulation could eventually support new approaches to protecting long-term brain health.

Bedroom Air Purifiers Reduce Blood Sugar Fluctuations By Nearly 8% In Human Trial
Researchers at NYU Langone Health found that improving bedroom air quality produced measurable improvements in glucose regulation among adults with prediabetes. In a randomized, double-blind clinical trial involving 150 participants, four weeks of HEPA air filtration reduced indoor fine particulate pollution (PM2.5) by 36%, lowered glucose variability by 7.7%, and reduced post-breakfast glucose excursions by 16.6% compared with sham filtration. Presented at the American Heart Association's Scientific Sessions in November 2026, the findings suggest that airborne pollutants may influence metabolic health and blood sugar stability, even in environments with relatively modest pollution levels. Although researchers have not established whether these improvements translate into reduced diabetes risk or long-term cardiovascular benefits, the trial provides evidence that modifying environmental exposures can affect glucose regulation without introducing a new dietary intervention or medication. Host Dave Asprey explores the relationship between indoor air pollution, inflammation, insulin signaling, continuous glucose monitoring, and metabolic flexibility, explaining why bedroom air filtration may represent an overlooked opportunity for improving metabolic health and reducing environmental stress.

Scientists Discover How The Immortal Jellyfish Can Reverse Its Own Development
Scientists studying Turritopsis dohrnii, commonly known as the immortal jellyfish, are uncovering the molecular mechanisms behind its extraordinary ability to reverse from an adult jellyfish into an earlier developmental stage and eventually produce new adults. An October 2026 BBC feature highlights research into the species' unusual cellular plasticity, including the ability of specialized adult tissues to undergo reprogramming and contribute to new developmental structures. A 2022 genomic study published in Proceedings of the National Academy of Sciencesidentified differences involving DNA replication and repair, telomere maintenance, oxidative stress regulation, stem-cell populations, and genes associated with cellular reprogramming. Unlike animals that simply regenerate damaged body parts, this jellyfish can reorganize its adult body and restart its developmental cycle, offering researchers an unusual biological model for investigating rejuvenation. Although the findings do not demonstrate that human aging can be reversed using the same mechanisms, they raise important questions about the future of regenerative medicine. Host Dave Asprey explores cellular reprogramming, epigenetic regulation, DNA repair, telomere biology, tissue regeneration, and biological age reversal, examining whether mechanisms found in nature could eventually help restore damaged tissues, rejuvenate aging organs, and improve the body's capacity for cellular repair.

Researchers Discover Fructose Can Help Ovarian Cancer Cells Spread Through A Surprising Metabolic Mechanism
Researchers at The Wistar Institute discovered that chemotherapy-surviving ovarian cancer cells can release fructose that helps neighboring cancer cells detach and spread through a previously unrecognized metabolic mechanism. Published in Nature Aging in July 2026, the research found that senescent cells, sometimes called zombie cells, released fructose as part of their senescence-associated secretory phenotype (SASP), altering mitochondrial complex I activity and signaling involving NAD+, sirtuins, and SREBP. These changes reduced cholesterol in cancer-cell membranes, weakened cellular adhesion, and increased metastatic dissemination in experimental models. Researchers also observed more extensive metastatic disease in mice receiving a high-fructose diet compared with glucose-fed controls, although the findings do not establish that dietary fructose causes cancer metastasis in humans. The research highlights how senescent cells can influence surrounding tissues through metabolic signaling rather than simply promoting inflammation or uncontrolled cell growth. Host Dave Asprey examines fructose metabolism, cellular senescence, mitochondrial function, cancer-cell signaling, and the tumor microenvironment, exploring why the metabolic activity of chemotherapy-surviving cells could become an important target for future cancer treatments and longevity research.

Brain Imaging Study Finds Higher Intelligence Linked To Less Dense Neural Wiring
Neuroscientists examining brain scans and cognitive performance in 757 adults discovered that higher reasoning scores were associated with lower estimates of cortical neurite density and branching complexity, despite a positive relationship between reasoning performance and overall cortical volume. Published in Nature Communications in 2018, the study analyzed two independent groups using advanced diffusion MRI to investigate how microscopic brain architecture relates to intelligence. The findings suggest that neural efficiency may depend partly on more selective organization of neural circuitry, potentially reducing redundant signaling and supporting effective information processing. Researchers also discussed synaptic pruning, the brain's natural process of eliminating unnecessary connections, as a possible contributor to more efficient neural networks. However, the study measured indirect imaging markers rather than counting individual synapses, and it did not establish that reducing brain connections improves intelligence. Host Dave Asprey explores neural efficiency, neuroplasticity, synaptic pruning, brain energy consumption, cognitive performance, and information processing, explaining why the organization of neural networks may matter as much as their overall size or complexity.

Get Chloe's book The Girl’s Guide To Guts at thegirlsguidetoguts.com

Gut microbiome, stool testing, colon cancer warning signs, ulcerative colitis, chronic constipation, fiber, inflammation, digestive health, and the connection between gut bacteria and biological aging.

Host Dave Asprey sits down with Chloe Melas, NBC journalist and author of The Girl's Guide to Guts, to explore what your poop reveals about your health, the gut microbiome, chronic inflammation, colon cancer warning signs, digestive disorders, and the connection between gut bacteria and longevity. After living with ulcerative colitis for 15 years, Chloe shares her experience navigating chronic constipation, abnormal bowel movements, repeated antibiotic treatments, and a healthcare system that often overlooked the role of nutrition, lifestyle, and gut health.

Chloe explains why your stool can serve as a daily health report card, revealing potential warning signs that deserve attention. She describes spending more than a decade without normal bowel movements, regularly checking for blood in her stool, and struggling with symptoms that many people mistakenly associate only with diarrhea. Dave and Chloe examine the differences between irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), Crohn's disease, and ulcerative colitis, along with the importance of recognizing changes in bowel habits. They also discuss the rise of colorectal cancer in younger adults, including Chloe's account of a woman whose rectal bleeding was initially attributed to hemorrhoids before she received a stage three colon cancer diagnosis.

The conversation explores how fiber, gut bacteria, and the microbiome influence digestive health and biological aging. Chloe describes how incorporating psyllium husk and other fibers into her routine coincided with a dramatic improvement in her symptoms and five years of remission. Dave explains how different types of dietary fiber interact with gut bacteria, why microbial diversity matters, and how stool testing can reveal information about the microorganisms living in your digestive tract. They discuss soluble fiber, prebiotics, resistant starch, polyphenols, methane-associated digestive issues, and the challenges of identifying which foods and supplements work best for an individual's gut.

Finally, Dave and Chloe examine the future of personalized gut health, microbiome testing, and unconventional digestive therapies. They explore fecal microbiota transplantation, experimental parasite-based treatments, the potential influence of environmental exposures, and the relationship between gut health, inflammation, and the brain. Chloe reflects on the importance of advocating for yourself, asking better questions, and recognizing that persistent digestive symptoms should not simply be accepted as normal. Together, they make the case for paying closer attention to bowel habits, understanding your microbiome, and taking a more proactive approach to long-term digestive health.

The Neuroscience of Addiction, Breaking Bad Habits, Childhood Trauma, Psychedelic Healing, Loneliness & Emotional Recovery

Host Dave Asprey sits down with Luke Storey, host of The Life Stylist Podcast and author of A Horse Named Lonesome, to explore the science of addiction, loneliness, childhood trauma, emotional healing, psychedelics, brain chemistry, and the surprising relationship between human connection and happiness. Drawing on nearly three decades of recovery from drug addiction, Luke explains why overcoming substance abuse doesn't necessarily resolve the emotional patterns behind it, how unresolved trauma can shape relationships and behavior, and why having fewer, deeper friendships may lead to greater fulfillment.

Luke shares his journey from childhood trauma and early substance use to long-term sobriety, revealing why he continued struggling with codependency, unhealthy relationships, and self-destructive patterns even after 20 years without addictive drugs. He discusses his controversial decision to explore ayahuasca and other psychedelics after two decades of sobriety, the emotional breakthroughs he experienced, and the importance of distinguishing personal healing experiences from approaches that may be appropriate for others. Dave and Luke examine the relationship between addiction, trauma, altered states of consciousness, meditation, and the brain's ability to change entrenched behavioral patterns.

The conversation turns to nicotine, dopamine, cravings, and the biology of addiction. Luke describes his experience with heavy nicotine use, dependence, and the cognitive and emotional challenges of stopping abruptly. Dave explores how nicotine delivery methods influence habitual behavior, the distinction between dependence and addiction, and the potential roles of mitochondrial function, cellular energy, ketones, and GLP-1 signaling in cravings and self-control. They also discuss modafinil, nootropics, NAD therapies, and how changing your physical and mental state can influence behavior, focus, and emotional regulation.

Dave and Luke also examine the hidden costs of obsessive self-improvement and health optimization. Luke reflects on periods when pursuing physical health and personal development became disconnected from the deeper purpose of living a meaningful life. They discuss the difference between healthy ambition and compulsive self-improvement, why physical performance alone cannot guarantee emotional well-being, and how relationships, purpose, and spiritual practices contribute to a more fulfilling life.

Finally, Luke introduces his new book, A Horse Named Lonesome, and explores why people can feel profoundly lonely even when surrounded by others. He shares how childhood isolation shaped his understanding of connection, why solitude and loneliness are fundamentally different experiences, and how reducing superficial relationships helped him develop a smaller circle of meaningful friendships. Dave and Luke discuss how trauma, negative thought patterns, and emotional disconnection can interfere with intimacy, and why cultivating genuine relationships may be one of the most important investments in long-term happiness and well-being.

You'll Learn:
Why overcoming addiction doesn't always resolve the childhood trauma, emotional patterns, and relationship difficulties that contributed to it
How Luke approached psychedelics after 20 years of sobriety, and what his experiences taught him about trauma and emotional healing
How nicotine dependence, dopamine signaling, and habitual behaviors influence cravings, focus, and self-control
Why mitochondrial health, cellular energy, ketones, and GLP-1 signaling are being explored in connection with addictive behaviors
How meditation, breathwork, psychedelics, and other altered states may influence emotional regulation and entrenched patterns of thinking
Why obsessive biohacking and self-improvement can interfere with happiness, relationships, and a meaningful life
How childhood loneliness and unresolved trauma can affect adult relationships, intimacy, and emotional connection
Why having fewer close friends may be more fulfilling than maintaining a large network of superficial relationships
How to distinguish healthy solitude from harmful isolation and build deeper, more authentic human connections

There's a 15 minute habit you can do every morning that kills insulin belly. That's the fat packed around your organs. It drains into your liver, forces your body to make more insulin, and insulin locks your fat cells shut so nothing can get out.

I know because 20 years ago I was 31, weighed 300 pounds, and my doctor told me my blood looked like sludge and I was headed for a heart attack. So I did exactly what he said. I trained six days a week, 90 minutes a day, for 18 months. My waist stayed at 46 inches.

Today that waist is gone. So is my arthritis, my brain fog, and my pre-diabetes. And it didn't start with a diet or a workout. It started with light.

In this video I'll show you two ways to test whether you have insulin belly (one takes 10 seconds and costs nothing), why a standard blood sugar test misses it for years, and the three levers that reversed mine.

You'll Learn:
What “insulin belly” is and why visceral fat poses different risks than fat under your skin
Why you can be “thin outside, fat inside”—and which measurements reveal more than BMI
What research on red light suggests about blood sugar and mitochondrial function
Why Dave prioritizes morning sunlight and a dark bedroom at night
Dave’s three timing rules for meals and movement to support insulin sensitivity
How cold exposure, brown fat, and gut bacteria may influence metabolic health
What Dave learned going from a 46-inch waist to a 32-inch waist

Scientists Test Vibrating Mattress To Help Clear Alzheimer's-Related Proteins From The Brain
Researchers at the University of Oulu in Finland tested a vibrating mattress combined with nitroglycerin, a blood-vessel-relaxing drug, in 29 healthy adults and found that blood levels of amyloid-beta 42 increased approximately 35% following the combined treatment. Published in Nature Communications, the study also identified MRI changes suggesting altered cerebrospinal fluid dynamics, potentially involving the glymphatic system and mechanosensitive Piezo1 ion channels. While the results suggest increased movement of brain-associated proteins into circulation, they do not establish that Alzheimer's plaques were removed or that cognition improved. Host Dave Asprey explores the potential of mechanical stimulation, nitric oxide signaling, and brain waste clearance as emerging approaches to neurodegenerative disease prevention, and why sleep and vascular health remain essential to protecting long-term cognitive performance.

Yale Researchers Discover Taurine Controls A Key Inflammatory Switch Linked To Aging
Yale researchers identified a previously unrecognized role for taurine in regulating the NLRP3 inflammasome, an immune signaling complex associated with chronic inflammation and biological aging. Published in Cell, the research found that activated macrophages released up to 80% of their intracellular taurine, while restoring taurine suppressed inflammatory signaling. Surprisingly, circulating taurine levels were higher in older adults than younger adults, challenging the assumption that taurine universally declines with age and highlighting the importance of intracellular nutrient regulation. Host Dave Asprey examines the connection between taurine, inflammaging, immune function, and longevity, explaining why cellular nutrient availability may matter more than blood concentrations and what this emerging mechanism means for supplementation and inflammation management.

Blood And Plasma Donation Shown To Reduce Forever Chemicals In Human Trial
A randomized clinical trial involving 285 Australian firefighters found that regular blood and plasma donation significantly reduced circulating concentrations of certain PFAS, the persistent environmental pollutants commonly known as forever chemicals. Published in JAMA Network Open, the study found that plasma donation every six weeks reduced average PFOS concentrations by 2.9 ng/mL over 12 months, compared with a 1.1 ng/mL reduction from whole-blood donation every 12 weeks and virtually no change in the control group. Because PFAS bind to proteins in blood, removing plasma offers a direct method of reducing circulating chemical concentrations, although the trial did not establish long-term health benefits. Host Dave Asprey explains why this physical removal strategy deserves attention alongside conventional detoxification approaches, and how reducing exposure through drinking water, food packaging, and environmental sources remains a critical first step.

HHS Eases Restrictions On Six Popular Biohacking Peptides Including BPC-157 And MOTS-c
On October 28, 2026, the Department of Health and Human Services announced a draft enforcement-discretion policy covering six compounded peptides: BPC-157, Epitalon, KPV, MOTS-c, Semax, and TB-500. Under the interim approach, HHS says it does not intend to take enforcement action against qualifying compounders when specific manufacturing, sourcing, formulation, labeling, and adverse-event reporting conditions are satisfied, while the FDA's formal regulatory evaluation continues. The announcement represents a significant shift for compounds being investigated or promoted for tissue repair, inflammation, mitochondrial function, cognitive performance, and longevity, although none received FDA approval through this action. Host Dave Asprey discusses what the policy could mean for peptide access, pharmaceutical regulation, product purity, and medical oversight, and why better manufacturing standards must accompany expanded access to experimental therapies.

Drinking Coffee Linked To 39% Lower Recurrence Hazard Of Atrial Fibrillation In Clinical Trial
A randomized clinical trial published in JAMA found that patients assigned to drink at least one cup of caffeinated coffee daily experienced fewer recurring episodes of atrial fibrillation or atrial flutter following electrical cardioversion than patients assigned to avoid caffeinated beverages. The six-month DECAF trial followed 200 adults and found arrhythmia recurrence in 47% of coffee drinkers compared with 64% of participants assigned to abstinence, corresponding to a 39% lower recurrence hazard in the time-to-event analysis. The findings challenge routine recommendations to avoid coffee among patients with existing atrial fibrillation, although the trial did not establish whether caffeine, coffee polyphenols, or associated behaviors produced the benefit. Host Dave Asprey explores caffeine's effects on cardiovascular function, adenosine signaling, and inflammation, explaining why individualized responses matter more than blanket dietary restrictions.
