The ongoing outbreak of hantavirus infections that originated with passengers on the Dutch cruise ship MV Hondius in April has generated concerns across the globe. This very rare occurrence has led to a number of deaths, required quarantining of passengers and prompted emergency responses from public health authorities in multiple countries.  On this episode of Raise the Line from Elsevier, we're tapping the expertise of a leading authority on the subject, Dr. Jamie Childs of Yale University, to provide you with a scientific understanding of hantaviruses and what level of threat is posed by this situation. In short, Dr. Childs believes this is not the start of a pandemic. “The Andes variant involved here is one of the most dangerous hantaviruses, but it is totally controllable with contact tracing.” This timely conversation with host Lindsey Smith is informed by Dr. Childs' decades of hantavirus research as well as learnings from his role leading the CDC's environmental investigation during the landmark 1993 hantavirus outbreak in the Four Corners region of the American Southwest. And be sure to stay tuned to hear his concerns about the factors complicating containment of the current Ebola outbreak in East Africa. Note: this conversation was recorded on May 19th, 2026.

When we think of occult, shamanic, or mystical beings, we tend to think in terms of spiritual abstraction, dissociated from the material world. But the occult simply means the hidden — the invisible world, whose effects on our fortune and health are real, even when the origins of their symptoms can't be detected with the naked eye. Long before the microscope, our ancestors were in relationship with that world: through ritual, altered states, the superstitions they hold, and the stories they told.  In this conversation, two poet-philosophers compare notes on how the imagination mediates between microbiological cultures and human culture — how the interface of myth, folklore, and story lend form to a realm that is invisible, but physical.  From fermentation to mythic mentation, this invisible world is not merely psychic or material in nature—it is meta-real.

#317 I'm a degree-qualified naturopath with over 20 years of clinical experience, with a primary focus on complex gut health conditions — and in this video, I'm doing something I've never done before. I'm turning the lens on myself. I recently got my own gut microbiome tested, and I want to walk you through every single result. I didn't get tested because I had gut symptoms — my bowels are actually moving beautifully. I got tested because I'd been dealing with over a year of persistent rosacea and wanted to know: could what's happening in my gut be connected to what's showing up on my skin? I also wanted to show you exactly what this test looks like when it's interpreted by someone who does this for a living. We cover every section of the report — the pathogen panel, the diagnostic GI markers, microbiome diversity and richness, short-chain fatty acids, TMA, emerging metabolites, the species table, and more. I also share the result that was flagged as severely abnormal — and why, in context, it almost certainly isn't. This is what it looks like to use real data to motivate real change — not because something has gone terribly wrong, but because catching the trajectory early is the whole point. What we cover What makes shotgun metagenomics different from other stool tests The targeted pathogen panel — what it tests for and what my results showed Pancreatic elastase — the result that flagged severely low, and why context changes everything Lactoferrin, calprotectin, zonulin, secretory IgA, and faecal occult blood Microbial diversity and richness — what we're aiming for and why it matters Butyrate, acetate, propionate, and TMA — what they mean and how diet influences them Prevotella copri — nuanced, misunderstood, and more common in traditional diets than you'd think Emerging markers, including GABA, and why we need to hold them lightly Human DNA elevation — and why collection context explains it My action steps and why seeing this data now motivates me to act I'm Lynda Griparic, a degree-qualified naturopath with extensive experience in complex gut health conditions, including SIBO, IMO, and chronic constipation.

Why do CDMOs keep building bigger stainless-steel facilities while their margins erode and Asian competitors undercut them on price? And what happens when big pharma decides to stop outsourcing altogether? The business model that sustained the industry for two decades is under pressure from every direction, and for many CDMOs, standing still is no longer a neutral position.In Part 2, Juergen Mairhofer, CEO of enGenes Biotech, shifts from the science to the stakes. Having spent over a decade building a company on licensing proprietary microbial technology rather than selling fermentation capacity, he brings a distinctive vantage point on where the CDMO industry is headed and what it will take to stay relevant.Here are some of the topics discussed:The need for innovation to stay competitive against lower-cost regions, and why capacity-focused business models are running out of road (03:08)How continuous manufacturing creates a competitive edge for CDMOs operating in high-cost regions (05:49)Practical advice for piloting continuous processing, building partnerships, and taking calculated risks before competitors do (06:36)The parallel universe of batch and continuous manufacturing, and how this duality will shape the industry over the next decade (08:24)What scientists need to know before spinning out a technology company: customer focus, cash discipline, and why the team is everything (09:49)Big pharma's return to in-house manufacturing and vertical supply chain integration, and why this creates opportunity for innovation-focused partners (12:12)Smart insight: Technology excellence is necessary but not sufficient. Juergen's closing word was simply "don't be afraid" and it carried weight precisely because it was not a platitude. The companies that will matter in ten years are those that start the hard work of innovation now, before the window closes.If you're interested in exploring more breakthroughs in continuous bioprocessing and the future of biotech manufacturing, check out these past episodes from the Smart Biotech Scientist Podcast:Episodes 85 - 86: Bioprocess 4.0: Integrated Continuous Biomanufacturing with Massimo MorbidelliEpisodes 153 - 154: The Future of Bioprocessing: Industry 4.0, Digital Twins, and Continuous Manufacturing Strategies with Tiago MatosEpisode 155: From Process Bottlenecks to Seamless Production: How Continuous Bioprocessing Changes EverythingEpisode 156: The Hidden Economics of Continuous Processing That Most Biotech Companies OverlookEpisodes 181 - 182: Innovating Continuous Bioprocessing with Vibrating Membrane Filtration with Jarno RobinEpisodes 209 - 210: From Batch to Continuous: Building Innovation Culture in Conservative Biotech Environments with Irina RamosConnect with Juergen Mairhofer:LinkedIn: www.linkedin.com/in/juergen-mairhofer-ab27a5benGenes Biotech GmbH website: www.engenes.ccSupport the show

What if continuous microbial manufacturing wasn't a pipe dream, but a reality quietly reshaping the foundations of bioprocessing?Meet Juergen Mairhofer, CEO of enGenes Biotech GmbH and a scientist with a rare dual fluency in molecular biology and bioprocess engineering. He's not just optimizing at the margins. He's devised a proprietary E. coli platform that radically stabilizes genetic stability and splits cell growth from protein production. Instead of stretching out fermentation for a few more days, he's running continuous E. coli processes for up to 40 days; something most believed impossible.Here's why this conversation is worth your notebook and a second listen:Why the commodity CDMO model struggles with innovation and how enGenes Biotech's model aligns business incentives with process improvement (02:37)Juergen Mairhofer's early experiences blending molecular biology and bioprocess engineering, and how a "DIY" mentality led to entrepreneurship (04:42)Strategy behind developing a proprietary E. coli strain that decouples protein production from cell growth (10:01)The benefits of continuous manufacturing: running up to 40-day E. coli processes, and how this compares to mammalian (CHO) systems (13:57)Economic and operational advantages: reducing facility footprint, lowering CAPEX/OPEX, and the necessity for innovation in global competition (19:25)How enGenes Biotech integrates upstream and downstream operations for fully end-to-end continuous production (17:50)Specific technical challenges: managing genetic drift, sterility, equipment, and process modeling in continuous systems (21:10)Smart insight: Technology excellence is the entry ticket, but it won't sell itself. The companies that will lead the next decade of bioprocessing are those willing to align their business model with process innovation, not just capacity utilization.If you're interested in exploring more breakthroughs in continuous bioprocessing and the future of biotech manufacturing, check out these past episodes from the Smart Biotech Scientist Podcast:Episodes 85 - 86: Bioprocess 4.0: Integrated Continuous Biomanufacturing with Massimo MorbidelliEpisodes 153 - 154: The Future of Bioprocessing: Industry 4.0, Digital Twins, and Continuous Manufacturing Strategies with Tiago MatosEpisode 155: From Process Bottlenecks to Seamless Production: How Continuous Bioprocessing Changes EverythingEpisode 156: The Hidden Economics of Continuous Processing That Most Biotech Companies OverlookEpisodes 181 - 182: Innovating Continuous Bioprocessing with Vibrating Membrane Filtration with Jarno RobinEpisodes 209 - 210: From Batch to Continuous: Building Innovation Culture in Conservative Biotech Environments with Irina RamosConnect with Juergen Mairhofer:LinkedIn: www.linkedin.com/in/juergen-mairhofer-ab27a5benGenes Biotech GmbH website: www.engenes.ccNext step:Need fast CMC guidance? → Get rapid CMC decision support hereOne bad CDMO decision can cost you two years and your Series A.

In this first installment of a three-part vineyard nutrition series, Dr. Markus Keller joins us to break down one of the most influential nutrients in vineyard management: nitrogen. We explore from the ground up.  Dr. Keller explains what nitrogen is, where it comes from in vineyard soils, and why it plays such a critical role in vine growth, fruit set, and overall vine performance. While nitrogen makes up 78% of the atmosphere, vines rely on soil processes to convert it into plant-available forms like nitrate. Dr. Keller details how nitrogen influences vigor, canopy density, fruit set, berry size, phenolic development, and even wine quality. The episode also dives into how soil type, organic matter, temperature, moisture, and cover crops affect nitrogen availability. For growers across diverse regions, this conversation highlights why vineyard nutrition strategies must be site-specific. Whether you're managing high-vigor blocks or navigating lean soils, episode one of our three-part series equips vineyard owners and operators with foundational knowledge to make smarter nitrogen decisions. In this episode, you will hear: Nitrogen primarily comes from soil organic matter, not rock minerals Microbial activity drives nitrogen availability in vineyards Both deficiency and excess nitrogen can reduce vine balance and fruitfulness Soil moisture and temperature strongly influence nitrogen mineralization Leaf blade tissue sampling offers improved precision for nitrogen analysis Follow and Review: If you enjoyed this episode, be sure to follow the podcast and leave a 5-star review on Apple Podcasts!

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
