Tiny Matters: Daily Summaries Delivered
by Multitude
Science shapes every facet of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning science podcast about the small science of big things. From the microbes behind deadly diseases to the molecules informing our search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its significance both today and in the past, asking questions like, "Can you de-extinct a species?," "Will we ever live on Mars?," and "After decades, why don't we have a cure for HIV?"

[BONUS] Colorful blood in nature and how a tick bite causes a meat allergy: Tiny Show and Tell Us #59
Why do humans have red blood, while other animals have green, purple, or even yellow blood? In this episode of Tiny Show and Tell Us, we explore the surprisingly colorful world of animal blood, from Antarctic ice fish with nearly transparent blood to green-blooded skinks and purple-blooded peanut worms. Then we enter tick territory and investigate how a tick bite leaves some people unable to eat red meat and other animal products. The answer involves a condition known as alpha-gal syndrome, where a tick bite can trigger an immune response to the alpha-gal sugar found in many mammals.See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

Secrets in the peat: Ghost lights, bog bodies, and life built on death
For centuries, ghostly lights floating over bogs have appeared in folklore. Known by names including will-o'-the-wisp, corpse candles, and ‘Lantern Jack,’ they’ve inspired stories of supernatural tricksters leading travelers astray, sometimes to their doom. But in 2024, scientists finally uncovered the chemistry behind the phenomenon. From there, we travel deep into the strange world of bogs. These waterlogged landscapes help cool the planet and have preserved ancient artifacts — including human bodies — for thousands of years, helping teach us about what life was like many millennia ago, but also providing insight into some of the diseases that plague humanity today, including Alzheimer's.Related episodes you may enjoy: Biofilms: The sticky, slimy communities behind some of medicine's toughest infectionsForaminifera: The one-celled predators that shaped our planet (and kept the receipts)See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

[BONUS] The ‘Tyrant Lizard Queen’ and how evolution shaped our anxious brains: Tiny Show and Tell Us #58
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.

The canaries in the coal mine: How sentinel species monitor our world
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.

[BONUS] Decoding dinosaur colors and the failure of postpartum care: Tiny Show and Tell Us #57
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.Related episodes you may enjoy: The Mothers of Gynecology: The centuries that led to today’s Black maternal mortality crisisDinosaur Fossils: Inspiring Jurassic Park and helping us predict Earth's futureSee Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.

How do you save a species?: Breakthroughs from cheetahs, red wolves, and 'spicy' toads
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?What is de-extinction, really?
