Send a textIn this episode of The Autoimmune RESET Podcast, I'm sharing some of the key ideas from a full-day practitioner training I recently delivered on arthritis — and why the way we think about joint pain needs to change.For decades, arthritis — particularly osteoarthritis — has been framed as a simple story of wear and tear. Something mechanical. Something inevitable. Something that happens as we age.But that explanation is incomplete.Joint health is not just about cartilage. It is about the immune system, the gut, the nervous system, metabolism, and the body's ability to resolve inflammation. Arthritis is often a systemic condition that happens to be expressed through the joints.In this episode, we explore the deeper physiology behind inflammatory joint symptoms, including:• The gut–joint connection and intestinal permeability • Microbial triggers linked to autoimmune arthritis • The role of short-chain fatty acids and immune tolerance • Omega-3 fatty acids and the resolution of inflammation • Why digestion and absorption are often overlooked foundations • Nervous system regulation and pain signalling • The importance of sequencing interventions rather than doing everything at onceI also share reflections from my own experience of living with significant joint pain for many years, and what I've learned from working with clients who move from daily inflammation and limitation to meaningful recovery.One of the most important messages in this episode is that healing rarely happens through quick fixes. It happens through a layered, strategic approach — stabilising foundations first, then building resilience over time.If you are living with joint pain, stiffness, autoimmune arthritis, or inflammatory flares, this conversation will help you understand why your symptoms may be happening and what you can begin to do about them.Because arthritis is not always inevitable. And it is very rarely just about ageing.arthritis, autoimmune disease, gut health, inflammation, omega-3, digestion, nervous system, joint pain, immune regulation, functional medicine

Seventy percent of the protein your herd uses for lactation is derived from the microbial population in her rumen. Researchers from UC Davis and Feedworks USA sought to learn more about how different substrates might impact rumen microbial efficiency. They did this with the ultimate goal of increasing the flow of protein available for absorption to help offset feed costs, recognizing protein is the highest cost of the ration, and likely the largest fraction to the cost of production on most dairies. “We know that efficency of growth in the rumen varies dramatically, nearly 2 fold. Microbes can use 1/3 of their energy for growth or as much as 2/3,” Hackmann described. His lab is using invitro cultures to attempt to determine why this variation exists. “If we can pinpoint cause then we can accomidate and make microbes grow more efficiently and deliver more protein to the ruminant at a lower cost.” Past models, used in ration formulation software such as CNCPS, claim rumen bacteria perform digestion more efficiently when fed cellulose, over glucose. However, featured work by Dr. Tim Hackmann's invitro lab suggests a different result. “We found there will be a larger mass of microbes that grow on glucose then cellulose but they also digest more, so the efficiency is not differnet.” Listen-in to this episode for in interesting dive into the expected changes in the rumen under these conditions. An added bonus banter from Dr. Benjamin Wenner, ruminant nutritionist with FeedWorks USA and co-author on the featured article, about the futuristic concepts possible for ruminant nutrition with mindful investment.

The gut-brain connection is deeper, weirder, and far more literal than we ever imagined. For years, we've been told that our 'gut feeling' is just a metaphor for intuition. But recent science suggests that your gut is actually a 'second brain'—a complex neural network of 100 million neurons that can operate entirely on its own, independent of the one in your skull.We aren't just talking about digestion; we're talking about a bidirectional superhighway where bacteria in your colon produce up to 90% of your body's serotonin and significantly influence your levels of GABA, the primary neurotransmitter for calm. Essentially, the 'critters' in your gut might be the master puppeteers of your mood, your sleep, and even your cognitive clarity.But as the market for 'gut health' explodes, the gap between marketing claims and clinical reality is widening. I interview Gabe Dough, the founder of Good Bru. His product bridges that gap using a specific combination of prebiotics and a resilient probiotic strain known as BC30, which I've been using.2:16 “All illness starts in the gut”6:50 Origins of autoimmune disease11:40 Probiotic vs Prebiotic20:43 Synbiotic vs Psychobiotic25:55 The truth about Probiotic yogurt30:58 Probiotics for PCOS34:41 Gut microbiome testing42:25 Probiotics vs Candida44:06 Probiotics for protein absorption44:25 Probiotics for children46:39 Probiotics for Psoriasis47:14 Probiotics for bone loss54:32 Digestion hacks epic feasting58:57 Weird science: Personality transplant via gut microbes1:03:50 Weird science: Microbial hijacking of craving control1:06:53 Gabe's supplement stack1:09:03 Probiotic cofactors1:12:03 More yogurt hacks1:16:42 Weird science: Brain as "PR department" for the gut1:19:33 Stress vs the “gut brain”1:21:01 Gut health as a tool for architecting personalityRead

In this episode of SpaceTime, we delve into the intriguing potential for life on the dwarf planet Ceres, explore NASA's latest mission to study the heliosphere, and celebrate the achievements of the University of Melbourne's Spirit Nanosat.Ceres: A Potentially Habitable World?Recent research published in Science Advances suggests that Ceres, currently a frigid and frozen world, may have once harboured conditions suitable for life. By modelling the planet's thermal and chemical history, scientists propose that Ceres could have sustained a long-lasting energy source, allowing for microbial metabolism. While there's no direct evidence of life, the findings indicate that Ceres had the necessary ingredients—water, carbon, and chemical energy—that could have supported single-celled organisms in its ancient past.Nasa's New Heliospheric MissionNASA has launched the Interstellar Mapping and Acceleration Probe (IMAP) to investigate the heliosphere, the magnetic bubble surrounding our solar system. This mission aims to enhance our understanding of solar wind and its interactions with interstellar particles, which are crucial for assessing space weather impacts on Earth. IMAP will operate alongside the Carruthers Geocorona Observatory and NOAA's Swifo L1 spacecraft, contributing to a comprehensive study of our solar environment.Spirit Nanosat's Milestone AchievementThe University of Melbourne's Spirit nanosatellite has successfully completed its initial mission phase, deploying its thermal management system and taking a selfie in space. Launched in December 2023, Spirit is equipped with a miniaturised gamma-ray detector to search for gamma-ray bursts, marking a significant advancement in small satellite technology and scientific exploration.www.spacetimewithstuartgary.com✍️ Episode ReferencesScience Advanceshttps://www.science.org/journal/sciadvNASA IMAP Missionhttps://www.nasa.gov/imapUniversity of Melbourne Spirit Nanosatellitehttps://www.unimelb.edu.au/Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-your-guide-to-space-astronomy--2458531/support.Ceres: A Potentially Habitable World?NASA's New Heliospheric MissionSpirit Nanosat's Milestone Achievement(00:00) New study claims the dwarf planet Ceres could once have been habitable enough for life(05:14) The Interstellar Mapping and Acceleration Probe will study the heliosphere(15:58) New study finds tropical fish are colonising new habitats because of ocean warming(18:07) Khloe Kardashian reportedly claims she's seen UFOs and experienced paranormal activity

In this episode of SpaceTime, we dive into groundbreaking discoveries on Mars, the intriguing atmosphere of Makemake, and the awe-inspiring total lunar eclipse that captivated millions.Potential Biosignatures on MarsNASA scientists have revealed that samples collected by the Perseverance rover from Jezero Crater may hold the best chance yet of uncovering evidence of past microbial life. The samples, taken from the rock formation known as Chiava Falls, exhibit characteristics that could indicate potential biosignatures. These findings suggest that Mars may have been habitable for longer than previously thought, challenging earlier assumptions about the planet's history.Atmosphere Discovered on MakemakeIn a remarkable discovery, astronomers have detected indications of a methane gas atmosphere on the distant dwarf planet Makemake. This finding, made using NASA's Webb Space Telescope, suggests the presence of a tenuous atmosphere or possibly cryovolcanic activity. Makemake, which resides in the Kuiper Belt, is now only the second known trans-Neptunian object, after Pluto, to have confirmed gaseous presence, revealing its dynamic nature and potential for active geology.Total Lunar EclipseA stunning total lunar eclipse has mesmerised observers across Australia, Europe, Africa, and Asia. This celestial event transformed the full moon into a blood-red spectacle as Earth's shadow obscured it. The eclipse lasted over five hours, showcasing the beauty of orbital mechanics and providing a thrilling experience for stargazers.www.spacetimewithstuartgary.com✍️ Episode ReferencesNaturehttps://www.nature.com/Astrophysical Journal Lettershttps://iopscience.iop.org/journal/2041-8205Become a supporter of this podcast: https://www.spreaker.com/podcast/spacetime-space-astronomy--2458531/support.Potential Biosignatures on MarsAtmosphere Discovered on MakemakeTotal Lunar Eclipse

What if we could grow nutritious, sustainable protein—not in months or weeks—but in just one day? This episode's guest is doing just that. Rather than going big with animal agriculture, MicroHarvest is going small with microbial agriculture.  A huge number of animals are used to feed both our pets and the animals we raise for food. Kate Bekers, the CEO and co-founder of MicroHarvest, is seeking to change that. She's running a fast-rising European biotech startup using fermentation to produce high-quality protein from microbes—in just 24 hours. Based in Hamburg and Lisbon, MicroHarvest is on a mission to reshape how the world thinks about protein production. Rather than growing plants or animals, they grow single-cell microbes in bioreactors, yielding a high-protein, micronutrient-rich ingredient that can be used in everything from animal feed and pet food to, eventually, human food. With 10 million euros raised and hopefully a new 30 million euro round on the horizon, their process is fast, efficient, and radically resource-light—requiring far less land, water, and energy than traditional agriculture. Already able to produce one ton of their product per day, MicroHarvest is proving that microbial protein isn't just a lab experiment—it's a scalable, real-world solution. In this episode, Kate shares what it takes to bring biotech innovation to market, and why she believes protein production should be faster, cleaner, and closer to the consumer. We talk about the company's entry into pet food and aquaculture, and what the future holds for sustainable protein made from the tiniest organisms on Earth. If you're curious about the future of food, circular economies, or how to build a business that's good for animals and the planet, this conversation is for you.
