    Episode 36 Season 7: Seahorse Dads, Dogs vs Horses, and Smarter Health with Dr. Shazma Mithani

    Send us a text A father that gives birth, a horse that says “no,” and an ER doctor who wants to keep you out of the hospital—this episode brings science and everyday choices into sharp focus. We start with a mind-bending dive into seahorses, where males carry the pregnancy and build a placenta-like environment from skin. New research shows familiar pregnancy genes at work inside the brood pouch, but with an unexpected hormonal switch: androgens, not estrogens, drive gestation. It’s evolution repurposing its toolkit—and a powerful reminder that sex roles in nature are more flexible than we think. From there, we move into animal-assisted therapy and the role of consent in touch. A new study comparing dogs and horses found that forced interactions with horses raised heart rate and lowered HRV, signaling more stress, while choice calmed people down. Dogs showed no significant difference between conditions, suggesting human perception and species-specific behavior shape outcomes. If you run therapy programs, the insight is simple and humane: build animal choice into sessions, especially with horses, and track long-term welfare alongside human benefits. Then ER physician Dr. Shazma Mithani joins us to turn insight into prevention. We talk helmets for anything on wheels or snow, why e‑scooters drive more severe injuries per use than bikes, and how regular checkups and screening prevent emergencies before they start. We break down wildfire smoke—how particulates inflame lungs and harm the heart and brain—plus when to wear a well-fitted N95 outside and how to upgrade home air with MERV 11–13 filters or HEPA purifiers. Finally, we tackle measles: an airborne virus that lingers for hours, demands 95% vaccination for herd immunity, and is best stopped with two doses of MMR. Unsure where to get trusted answers? Talk to your doctor, pharmacist, or public health nurse, and lean on credible sources rather than influencers. If this helped you think differently about biology, safety, or public health, tap follow, share it with a friend, and leave a review with your biggest takeaway—we’ll feature our favorites next week.

    Episode 35 Season 7: Coffee, Cats, And The Science Between

    Send us a text Coffee may nudge biology, but only within limits. We dig into new research suggesting that three to four cups a day align with longer telomeres for people with severe mental illness, then challenge the hype with the caveats that matter: observational design, smoking as a confounder, wildly different cup sizes and brew methods, and the reality that more caffeine can erase potential benefits. We translate the science into practical guidance—why moderation beats megadoses, how 400 mg per day became a sensible upper bound, and where sleep and stress fit into the bigger picture of healthy aging. Then we pivot to a feline mystery that spans millennia. Long before house cats padded through Chinese homes, leopard cats were the stealthy mousers around early settlements, drawn by grain and the rodents it attracts. Using mitochondrial DNA from ancient remains—paired with clues from art—we trace the species shift around the eighth century as domestic cats, descended from the African wildcat, traveled the Silk Road and found their place beside people. Tameness, tolerance, and a knack for living close to humans helped them outcompete their wild cousins in a world reshaped by trade and urban life. Across both stories runs one thread: human routines create niches that biology rushes to fill. Our cups change our days at a cellular level, and our granaries and roads alter which animals share our spaces. If you love clear science, a bit of myth-busting, and the unexpected link between breakfast and ancient history, you’ll feel right at home here.

    Episode 34 Season 7: Brain Wash, Golden Genes, and The Chief Bubble Dude to chat BUBBLES!

    Send us a text When the brain gets knocked, it fights back—at least for a while. We open with new research that uses ALPS MRI to watch the glymphatic “waste rivers” of the brain as they surge after repeated head impacts and then falter when the system is pushed too far. That real-time look at fluid flow explains why early symptoms can be misleading and why rest, recovery windows, and better sideline calls aren’t just policy—they’re neuroprotection. We talk sports protocols, long-term risk, and how biomarkers could warn athletes before decline sets in. Then we lean into joy with rigor. Our pet science segment dives into a Cambridge study of more than a thousand golden retrievers showing that genes tied to trainability, fear of strangers, energy, and dog-to-dog aggression overlap with human genes for anxiety, depression, and intelligence. It’s not destiny; it’s sensitivity. We unpack how emotional regulation genes shape learning and coping, why some “bad” behavior is actually distress, and how training plans can be kinder and more effective when they support the nervous system, not just reward the behavior. To cap it off, we welcome John Reider,, the chief bubble dude behind Atomic Bubbles, for a whimsical masterclass in safe, scented bubbles for pets. He breaks down cosmetic-grade ingredients, water-soluble fragrances, and machine-friendly formulas that make durable bubbles dogs and cats actually chase. We explore lavender and pheromone-infused bubbles as floating diffusers for calming anxious pets, plus practical notes on storage, allergy concerns, and why bacon and peanut butter scents work without real allergens.

    Episode 33 Season 7: Cancer Clues, Dog Socialization, and Interview with Author Melanie Kaplan on Lab Dogs

    Send us a text A vaccine built for a virus might be whispering a powerful message to cancer care. We dig into a new Nature paper suggesting that mRNA COVID shots could enhance the effectiveness of checkpoint inhibitor immunotherapy—especially in non‑small cell lung cancer and melanoma—by acting as an immune alarm that sharpens anti‑tumor responses. The data is retrospective, not causal, so we break down why the signal is exciting, where confounders can hide, and what the next generation of trials must test: timing, vaccine type, biomarkers, and who stands to benefit most. From there, we switch gears to the first weeks of a dog’s life. A small but detailed study of Australian breeders maps nine practical socialization steps—novel objects, varied surfaces, calibrated sound exposure, hands‑on handling, human visitors, other animals, off‑site trips, car rides, and rotating environments—that build confident, adaptable companions. We compare three rearing strategies, from uniform protocols to individual puppy plans, and connect these choices to fewer fear issues, better training outcomes, and smoother vet and grooming visits down the line. Journalist and author Melanie Kaplan joins us to share Hammy’s story—a beagle rescued from a research lab—and the deeper reporting behind her book, Lab Dog: A Beagle and His Human Investigate the Surprising World of Animal Research. We talk about why beagles became the default lab dog, the emotional toll and resilience of retired animals, and the promising rise of non‑animal alternatives like organs‑on‑chips, human cell models, and computational toxicology. With FDA and NIH signaling support for methods that are more humane and more predictive, there’s a real path to better science with less harm.

    Episode 32 Season 7: Pumpkins That Clean The Earth and Pets That Heal The Heart

    Send us a text Ever wonder how a pumpkin could help clean a toxic field—and why your dog might boost your mood as much as a wedding ring? We unpack both, starting with fresh research from Kobe University that reveals how a small amino acid tag on major latex-like proteins pushes pollutants into plant sap. That single routing decision explains why some gourds move stubborn chemicals like PCBs all the way to their fruits, illuminating both the promise of phytoremediation and the risk if contaminated soils meet our dinner tables. We talk practical implications for agriculture too—how breeders and bioengineers could tune protein binding and secretion to create safer crops while using separate plots for soil cleanup. Then we turn to the science of happiness with a study that estimates cats and dogs can elevate life satisfaction on par with being married or seeing friends often. The researchers used instrumental variables to tease causation, not just correlation, and the findings match what many of us feel: pets reduce loneliness, add structure, and get us moving. We dig into the nuance—pets offer deep comfort and presence, while people bring complex emotional and intellectual support—and why the best lives layer both. If this mix of plant science, pet happiness, and real-world tips resonates, follow the show, share it with a friend, and leave a quick review so more curious listeners can find us.

    Episode 31 Season 7: Polar Bears Leftovers, And Dog Judgments

    Send us a text A top predator that “wastes” food and ends up feeding an entire ecosystem? That paradox sits at the heart of our latest exploration into polar bear behavior and the hidden scaffolding of the Arctic food web. We unpack new research estimating that each polar bear leaves roughly 300 kilograms of edible remains annually—amounting to millions of kilograms across the region—and why those leftovers are vital calories for Arctic foxes, ravens, gulls, snowy owls, and even wolves. By focusing on blubber for maximum energy return, polar bears inadvertently act as providers in a landscape where every calorie matters, and we trace how shrinking sea ice threatens not just bears but the scavengers who depend on their kills. From icy shores to living rooms, we then tackle a beloved belief: can dogs judge human character? A Kyoto University study with 40 pet dogs put that idea to the test using a generous-versus-selfish setup. The result: no reliable preference for the kind human, even after direct interaction. We break down what this means for canine social cognition, why food-based tasks may miss the mark, and how ethics limit what scientists can test. Rather than a simple moral radar, dogs may rely on a complex blend of context, prior reinforcement, and human cues that are hard to capture in a two-choice experiment. Along the way, we share field notes from polar bear country, practical insights for interpreting your dog’s behavior without overreading the wag, and a clear view of how climate change reshapes energy flows you rarely hear about. If you care about wildlife science, animal behavior, or how small choices ripple through entire systems, this one offers fresh data and useful takeaways. Enjoy the show?

    Episode 30 Season 7: How A Solar Eclipse Changed Bird Behaviour And What Kids Get Wrong About Dogs

    Send us a text The sky went dark at midday, the temperature dipped, and a continent held its breath. We chased the total solar eclipse to Texas and came back with more than a memory—fresh science on how birds react when day vanishes and returns a few minutes later. Leveraging a blend of community observations, autonomous recorders, and BirdNET machine learning, researchers tracked behavior from Mexico to Canada and found a clear pattern: movement slowed during totality while vocalizations spiked, followed by a pseudo-dawn burst when the light returned. Some species, like American Robins and Barred Owls, showed dramatic shifts; others didn’t budge, pointing to species-specific sensitivity to light. That sudden flip from light to dark is more than a spectacle—it’s a powerful biological cue. We connect the dots to artificial light at night, from migration disruptions to window strikes, and explore how city lighting policies and dark-sky practices can protect wildlife without sacrificing safety. When the whole sky changes at once, you see how deeply behavior is tuned to brightness. It’s a rare, elegant experiment you can’t reproduce in a lab, and it gives us practical guidance for urban design and conservation. Back on the home front, we turn to a concern every family with pets and kids faces: children often misread dog body language. New data show that four- to seven-year-olds frequently mistake angry dog faces for happy ones, with high error rates even at seven. Most bites happen at home, during child-initiated contact, and without supervision. We share simple, actionable steps—teach a few key cues, keep greetings calm, supervise play, and give dogs guaranteed safe spaces—to preserve the empathy and comfort dogs bring while lowering risk.

    Episode 29 Season 7: Baby Brains, Play Wild Dogs, and Vet Chat with Dr. Nancy Kay

    Send us a text A newborn with higher pTau217 than an adult with Alzheimer’s—what would that mean for how we detect, define, and treat dementia? We dive into a startling new finding that reframes tau phosphorylation as a dynamic, reversible process rather than a one-way street. From the costs and tradeoffs of PET scans and CSF analysis to the promise of new blood tests, we lay out how clinicians navigate biomarkers and why context matters. If babies and even hibernating animals can toggle tau safely, we might be looking at a new horizon for Alzheimer’s research—one that prioritizes regulation over blunt suppression and respects the difference between signals and symptoms. Then we turn to our dogs and a different kind of brain science: play that looks a lot like behavioral addiction. In a study of high-drive pets, some dogs pursued play so intensely they ignored food and struggled to settle once the toy disappeared. The kicker? It’s not the toy—it’s the play. We unpack how anticipation and reward loops shape behavior, why shepherds and terriers tend to lean in hard, and how to channel that energy with structured games, clear start/stop cues, and decompression routines that protect both joy and well-being. Our guest, Dr. Nancy Kay—veterinarian and small animal internal medicine specialist—brings practical wisdom to family life with pets. She explains how to choose a dog that truly fits a home with kids, why supervision and respect rules beat wishful thinking, and how to steer clear of puppy mills and dog auctions with two simple safeguards: never buy from pet stores and never purchase sight unseen. We talk about her middle-grade novel, “A Dog Named 647,” her advocacy guide “Speaking for Spot,” and the unforgettable cases that come with a life in medicine—from swallowed treasures to high-stakes rescues. It’s science that matters, compassion that lasts, and stories that stick. Enjoy the conversation? Follow, share with a friend, and leave a quick review to help more curious listeners find the show.
