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.
