Groundbreaking neuroscience research reveals that the female brain contains specialized "rejection neurons" in the ventromedial hypothalamus—distinct circuits dedicated to active, defensive boundary-setting that can even override hormonal signals. In this episode, we explore: • How fiber photometry lets scientists watch rejection neurons "light up like fireworks" • Why the brain...

Science Catches Up to Conscience: How The UK's Bets on Phasing Out Animal Testing
Send us a text 📖 Read the companion Substack essay In November 2025, the UK announced something unprecedented: a £75 million strategy to aggressively phase out animal testing—backed not primarily by ethical arguments, but by scientific evidence that the alternatives are often more accurate predictors of human outcomes. This episode unpacks three critical elements: The Technology: Organ-on-a-chip systems smaller than credit cards, lined with human cells. 3D bioprinted tissues that function for...
