Tiny Matters

In this special crossover episode, Tiny Matters welcomes Alexis Pedrick, host of Distillations from the Science History Institute. You’ll hear the Distillations episode “The Mothers of Gynecology” — a powerful investigation into the racist origins of gynecology and the ongoing maternal health care crisis that disproportionately affects Black mothers. Through interviews with historians, clinicians, midwives, doulas, and public health researchers, the episode traces how racist myths about Black bodies — especially beliefs about pain tolerance — continue to shape medical care and outcomes. Following the episode, we unpack some of what you’ll hear, from the horrific exploitation of enslaved women by J. Marion Sims, to modern-day disparities that affect even the wealthiest, most famous Black mothers, including Beyoncé and Serena Williams.

In this episode of Tiny Show and Tell Us, we go from nerdy house-party physics to the brutal realities of morning sickness (can you say range!). First, we unpack what 5D data storage is and debate what we’d personally toss into the “Memory of Mankind” salt mine in Austria. Then we tackle a listener’s question about whether science has any updates on what causes severe morning sickness.

In 2019, Nathan Hudson-Peacock was serving as an expedition doctor to a group hiking in the Indian Himalayas. At around 17,000 feet, a climber suddenly went from having a mild headache to a life‑threatening cerebral edema. On top of that, a storm was closing in. So, what did he do? How do expedition doctors keep people alive in the harshest places on Earth? Tune in to this week’s episode to find out. In it, we chat with Nathan as well as high altitude physician Monica Piris, who has spent much of her time on Everest. We dig into the world of expedition medicine: the preparation, the danger, the breathtaking environments, and the moments that can reshape your understanding of the planet and the impact of climate change.
