Chapter 1 – Intertrigo: Prevention, Work-Up, and When (Not) to Use Antibiotics (00:11) John introduces the podcast episode and the hosts. (02:39) John welcomes Dr Laura Buckley (Senior Lecturer, Veterinary Dermatology, University of Liverpool) and asks what “brachycephalic” means and which breeds it covers. Laura explains shortened muzzles and broad, domed heads; the most extreme include French and British Bulldogs, Pugs and Boston Terriers, with Cavaliers, Chihuahuas and Dogue de Bordeaux also affected. (04:00) Sue notes their huge popularity in UK primary care. Laura adds that around 40% of her clinic can be French Bulldogs, with brachycephalics a very large overall share. (04:33) Sue asks which skin problems are most common. Laura explains that atopic dermatitis and otitis (externa/media) lead, with interdigital furunculosis also frequent. Cavaliers often show primary secretory otitis media. Skin-fold dermatitis (intertrigo) and muzzle furunculosis are common, and lesions can form over bony prominences where itchy dogs rub. (06:15) Sue asks what intertrigo is and why brachys get it. Laura explains shortened muzzles leave redundant skin that folds around eyes and muzzle, creating humid, low-airflow pockets that accumulate keratinous/sebaceous debris. Microbial overgrowth follows; bristly coats plus rubbing traumatises follicles and escalates inflammation. (08:06) Sue asks about prevention. Laura suggests daily fold hygiene from the start: clean away debris; consider antiseptic wipes (e.g., chlorhexidine) once or twice daily, and increase during flare-prone periods. (09:15) Sue highlights how early routines improve compliance and handling; Laura agrees it gives a “head start,” especially as atopy often appears within the first three years. (10:08) John asks how early disease presents and how to work it up. Laura explains earliest signs are diffuse erythema in the fold, then partial/complete alopecia, erosion/ulceration, crusting; severe untreated cases may progress to folliculitis and even deep pyoderma. (11:48) Sue asks about cytology. Laura explains it's pivotal: expect keratinous debris with cocci (staphylococci) or Malassezia in overgrowth; neutrophils with intracellular bacteria indicate infection and guide therapy. (12:57) John asks if systemic antibiotics are ever needed. Laura explains they're rarely indicated: most cases respond to topical antiseptics/antimicrobials plus strong anti-inflammatory control. Consider systemic antibiotics only for genuine deep, painful, draining pyoderma, immunosuppression, poor feasibility for topicals, or proven topical failure - always post culture & susceptibility. (15:47) John asks how she controls inflammation. Laura uses topical glucocorticoids (often in combination products). For severe inflammation, short anti-inflammatory courses of prednisolone (~0.5–1 mg/kg for a few days before tapering) can calm tissue so topicals can work. (16:48) Sue asks about long-term routines and when to consider surgery. Laura advises daily fold cleaning (once–twice daily) and twice-weekly topical anti-inflammatories (e.g., hydrocortisone aceponate or mometasone) with minimal systemic absorption; discuss surgery if medical care is impractical, or if maintenance fails with frequent relapses or recurrent infections. Chapter 2 – Viral Pigmented Plaques (VPP) (19:33) John moves to VPP and asks which brachy breeds are affected. Laura most often sees Pugs, plus Boston Terriers, Chihuahuas and French Bulldogs. (20:25) Sue asks what they look like. Laura describes numerous, heavily pigmented, slightly raised plaques that may begin flatter and become scaly, verruciform and hyperkeratotic over time. (22:00) Sue asks how to differentiate melanoma. Laura says biopsy/histopathology is the diagnostic choice; FNAs from plaques are often low-cellularity keratinocytes, whereas melanoma cytology differs. (23:43) John asks if plaques regress. Laura explains most persist or increase, likely due to a virus-specific, genetically influenced immunodeficiency in otherwise healthy, often young dogs. For treatment, Laura notes most are cosmetic, but very rarely plaques can transform to SCC, so monitoring matters. Limited numbers can be removed surgically or with laser; for numerous lesions consider systemic/medical options (e.g., azithromycin, interferon, retinoids, vitamin A, topical imiquimod) with variable success. (25:35) Sue summarises a primary-care approach: monitor unless numerous, pruritic, function-limiting or rapidly changing. Laura agrees; schedule regular reviews. Chapter 3 – Seasonal Flank Alopecia (SFA) (26:30) Sue introduces SFA and asks what it is and why it happens. Laura explains it's a localised cyclic follicular dysplasia linked to photoperiod and melatonin; predisposed breeds include Boxers, Affenpinschers, British Bulldogs, Staffies and Chihuahuas. (29:40) John asks about geography. Laura notes seasonality is more marked away from the equator where day-length swings are greater. Sue recalls light-box data suggesting equal photoperiod may prevent SFA; both agree the pattern fits a light/melatonin mechanism. (30:18) Sue contrasts the clinical picture with endocrine alopecia. Laura explains SFA shows sharply demarcated, bilateral flank patches (± hyperpigmentation). Endocrinopathies tend to be diffuse, affect coat quality and other sites (e.g., tail). (32:27) Sue asks differentials and work-up. Laura highlights hypothyroidism and Cushing's; use signalment and systemic signs, then haematology/biochemistry ± T4/TSH and targeted endocrine tests as indicated. (33:03) Sue asks about monitoring. Laura expects regrowth in spring within 1–4 months as day length rises, though a minority become permanently alopecic. (35:45) John asks about treatment. Laura reassures it's cosmetic once endocrinopathies are excluded; many owners opt to observe. For those wanting intervention, oral melatonin and increased light exposure are reasonable. (37:30) John thanks Laura and invites her for episode 2!

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

My guest today is Dr. Kenda Rigdon. Dr. Rigdon is a microbiologist with a PhD in microbiology and virology from the University of Alabama at Birmingham. Drawing from her expertise, she explores how the gut's microbial ecosystem—comprising bacteria, yeast like Candida and Malassezia, and other microbes—interacts with genetic and epigenetic factors to influence Autism. Dr. Rigdon highlights the critical role of the birthing process, particularly how vaginal delivery seeds a newborn's gut with beneficial microbes like lactobacillus, setting the stage for healthy development in the first three years. She also delves into how yeast overgrowth, nutrient competition (e.g., for tryptophan), and environmental factors like manganese and glyphosate exposure can disrupt this delicate ecosystem, potentially exacerbating autism-related symptoms.Dr. Rigdon shares insights into the surprising links between melanin, Neanderthal DNA, and Autism. She discusses how specific genetic mutations, such as MTHFR and PAI1, can intersect with Autism. Additionally, she connects melanin production—potentially influenced by gut yeast like Malassezia—to neurological health, drawing parallels with conditions like Parkinson's. By viewing the gut as a dynamic ecosystem shaped by birth, diet, and early development, this episode offers a fresh perspective on Autism's microbial roots and practical implications for health, urging listeners to reconsider modern birthing practices and dietary choices in fostering a balanced gut microbiome.Dr. Rigdon X https://x.com/KendaRigdonDaylight Computer Companyuse "autism" for $25 off athttps://buy.daylightcomputer.com/RYAN03139Chroma Iight Devicesuse "autism" for 10% discount athttps://getchroma.co/?ref=autism0:00 Dr. Kenda Rigdon1:14 Journey into Microbiology4:08 The Gut's Ecosystem8:21 Genetics, Autism, & The Microbial Connection13:08 MTHFR & PAI1: Homocysteine, Methionine, Folate20:21 The Role of Yeast in Health & Disease; Serotonin, Candida26:39 The Fight for Tryptophan31:14 Impact of Birthing Method on Gut Health (!)33:13 Modern versus Evolutionary Births, Breastfeeding; Oxygen, Acidity, PH37:15 Melanin, Cell Protection, Neanderthal DNA, Autism40:46 Neuromelanin; Biological Energy, Melanocytes43:20 Neanderthal's & Modern Disease & Environments47:23 Microbes in the Brain53:21 Manganese & Gut Health58:22 Gut-Brain Connection & Microbial Balance01:03:19 Early Gut Health & Development; Modern Insults01:07:21 Future Direction in Gut Health & Kenda's Passion & LoveX: https://x.com/rps47586YT: https://www.youtube.com/channel/UCGxEzLKXkjppo3nqmpXpzuAemail: info.fromthespectrum@gmail.com

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.

The rover's findings include unique boxwork patterns formed by groundwater, suggesting that even as Mars dried up, water was still present below the surface. As Curiosity ascends Mount Sharp, scientists are eager to understand the implications of these patterns and the mineral cements involved, which may hold clues to Mars' climatic history and the potential for ancient microbial life.Solar Flares and Weather PatternsA groundbreaking study published in the Astronomical Journal has uncovered a connection between solar flares and short-term changes in weather patterns on exoplanets. Researchers found that flares from a planet's host star can cause measurable climate shifts within days, highlighting the importance of solar activity in modulating atmospheric behavior. This research not only enhances our understanding of exoplanet habitability but also suggests that solar variability may influence weather systems on Earth, particularly in volatile regions.Nasa's In-Flight Imagery ProjectNASA's Scientifically Calibrated in Flight Imagery (SCIFLI) team is set to gather vital data during the reentry of a European aerospace company's demonstration capsule.

On this ID the Future from the archive, host Jonathan Witt speaks to molecular biologist and professor Dustin Van Hofwegen about his research into the engineered complexity in microbial life. Hofwegen shares his research on the famous decades-long E. coli evolution experiment conducted by Richard Lenski, which showed the sudden appearance of an ability to utilize citrate after many generations. However, Van Hofwegen's own experiments demonstrated that this "evolutionary innovation" actually points to the intelligent design built into living systems instead of an undirected process like natural selection.
