Tiny Matters
Multitude
Science shapes every part of our lives, but so much of its influence is overlooked or buried in the past. Tiny Matters is an award-winning podcast about tiny things — from molecules to microbes — that have a big and often surprising impact on society. From deadly diseases to forensic toxicology to the search for extraterrestrial life, hosts and former scientists Sam Jones and Deboki Chakravarti embrace the awe and messiness of science and its place in history and today, and how it could impact our world’s future. New episodes every Wednesday. Tiny Matters is brought to you by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude.

The rapid evolution of lactose intolerance (or, in fact, lactose tolerance)
Sam was an avid eater of greasy, cheesy pizza until her early 20s. Now, dairy has her running to the bathroom (tmi). Why is that the case for so many people all over the world? This week’s episode covers what causes lactose intolerance, why it’s not the same thing as a dairy allergy, and what might have caused a rapid shift in humans’ ability to digest lactose.

Dreaming: Why we hallucinate while asleep (and do spiders do it too?)
A recent study looking at sleeping spiders left Sam and Deboki with a lot of questions, namely, “Do spiders dream? And why do we humans dream?” In this episode of Tiny Matters, you’ll hear all about dreaming and its connection to sleep, and learn what big questions the field is still trying to answer.

Wastewater is helping us track disease outbreaks. Could it predict a future pandemic?
When you wash your dishes, take a shower, or flush a toilet you send a bunch of waste into your local sewer. But wastewater isn’t just filled with things like food scraps, soap, and feces—it also contains microbes, like viruses. During the pandemic, scientists realized how powerful a tool wastewater is for tracking many diseases, including COVID-19. Links to the Tiny Show & Tell stories here and here.

If the Milky Way could talk, what would it tell us?
Sam and Deboki chat with astrophysicist and folklorist Moiya McTier about her new book, The Milky Way: An Autobiography of Our Galaxy. It’s a fascinating read about our galaxy’s past and future, what scientists have uncovered about it, and what people have been inspired to create by studying it. Pick up a copy online or on bookstore shelves now.

Regenerating a limb (or brand new body)
Regeneration is a hot topic in the sciences, and for good reason. We humans are not known for being great at regenerating, but if we could understand how other organisms do it so easily we might be able to heal a spinal cord injury or damaged organs and limbs. Or we could even slow the aging process and not suffer from diseases like Alzheimer’s. Links to the Tiny Show & Tell stories here and here.

Preservatives: From ancient methods to today's plastic-wrapped Twinkies
Humans have been finding ways of preserving food for thousands of years—long before the invention of silica gel packs that absorb moisture or chemicals that keep away bacteria and mold. This week’s Tiny Matters is about the evolution of food preservation and the regulations that came about to keep us safe from the more dangerous food additives we came up with (ahem, arsenic candy).

Smallpox is the only human infectious disease we've eradicated. Why?
On May 8, 1980, the World Health Organization declared that smallpox—a highly-deadly disease in humans—had been eradicated. Today it’s still the only one we’ve completely wiped out. So, how’d we do it? And why haven’t we done it for the many other diseases that plague us, like COVID-19? Links to the Tiny Show & Tell stories here and here.

Why you should care about sharks (and why Sharknado wasn't totally wrong)
Marine conservation biologist David Shiffman joins Tiny Matters to chat about sharks and his new book Why Sharks Matter. We talk weird physiology, misconceptions, cinematic jump scares, Sharknado easter eggs, and science-backed activism. Check out Why Sharks Matter here.

Decades later, people are still dying from the 9/11 terrorist attacks
On September 11, 2001, nearly 3,000 people died, many of whom were first responders. Today, World Trade Center first responders who are still alive are being diagnosed with illnesses like lung disease and cancer more often than the general population. Many scientists say the air pollution caused by the terrorist attack is to blame. Links to the Tiny Show & Tell stories here and here.

The deadly London smog that changed pollution regulation forever
On December 5, 1952, the city of London was engulfed in a lethal black haze that killed thousands of people. This event, now known as the Great Smog, altered how London and much of the world viewed air pollution, and led to environmental policies that have no doubt saved many lives since then.
