In the heart of The Hague, Netherlands, the museum Mauritshuis displays some of the world’s most iconic art in its Royal Cabinet of Paintings, including ones from Rembrandt and Vermeer’s Girl with a Pearl Earring. But there’s another oil painting by Vermeer that is also quite famous, called View of Delft — it's of his hometown, created around 1660. The painting is a cityscape — the only one Vermeer ever painted — a snapshot of the Dutch city of Delft from across the Schie River. In it you see the city’s beautiful architecture on full display, including buildings with striking red roofs. Well, at least they used to be red. Today they have a pink-ish hue and if you looked at the painting up close, you’d see that they are covered in white spots. And what may come as a surprise is that they are, in fact, soap. In today’s episode of Tiny Matters, we’re going to talk about the weird chemistry of soap, what ancient soap was like, and why scientists are finding soap in old oil paintings.

Why does your brain sometimes react to a stressful meeting or traffic jam like you’re being hunted by a lion on the savannah? In this episode of Tiny Show and Tell Us, we explore the evolutionary roots of anxiety, why our internal alarm system sometimes misfires, and how treatments can help some people. Then paleontologist and author Riley Black joins the show to talk about her new book Tyrant Lizard Queen: The Love, Life, and Terror of Earth’s Greatest Carnivore. She shares why T. rex is a much more complicated dinosaur than the movie monster we’re used to seeing. We hear about how T. rex grew, hunted, weathered dramatic environmental changes, and fit into her ecosystem.

For decades, coal miners relied on canaries to warn them about deadly carbon monoxide underground. Canaries were retired from that work at the end of the 20th century, but today scientists still rely on certain organisms, referred to as sentinels, to reveal hidden environmental threats. In this episode, we trace the history of the canary in the coal mine to today and explore how researchers use songbirds, mussels, and oysters to monitor mercury, industrial pollution, and other contaminants that can linger in ecosystems for generations.

In this episode of Tiny Show and Tell Us, a listener asks why maternal mortality rates in countries like the U.S. and Canada have risen while many other wealthy nations have seen them plateau or even decrease. We talk about postpartum health, racial disparities, access to care, and why support after birth can be just as important as care during pregnancy and delivery. Then we switch gears and discuss how we know the colors of some dinosaurs. The answer lies in tiny fossilized structures called melanosomes, which allowed researchers to reconstruct some of the colors of dinosaurs.

Cheetahs carry the genetic scars of an Ice Age bottleneck, red wolves are so rare that every egg matters, and harlequin frogs need their natural toxins restored before they can thrive in the wild again. But avoiding extinction requires far more than protecting habitat alone. In this episode, we talk with scientists at Smithsonian's National Zoo and Conservation Biology Institute to explore cutting-edge science helping these animals not just survive but thrive, including innovative reproductive technologies like ‘ovary-on-a-chip.’ Similar episodes you may enjoy: Extinction: Rethinking the dodo's demise, and could a supervolcano threaten humanity's future?

In this episode of Tiny Show and Tell Us, we first discuss funnel-web spiders, who are among the most venomous spiders on Earth. Maybe somewhat paradoxically, their toxins are being studied to treat human disease and chronic pain. Then we talk with historian Claire Aubin about J. Willard Gibbs’ grave at Yale, where she’s a professor. Gibbs was a quiet scientific genius whose work transformed chemistry. He was also seemingly a very cool dude, and today his gravesite is decorated by students seeking good luck before exams. Check out This Guy Sucked wherever you get podcasts!
