    Tiny Matters

    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, “how was IVF invented?,” “what do glaciers tell us about Earth’s ancient past?,” and “why is smallpox the only human infectious disease we’ve eradicated?”

    Tiny Matters is created by the American Chemical Society, a non-profit scientific organization based in Washington, D.C., and is produced by Multitude. New episodes every Wednesday, wherever you listen to podcasts.

    Preservatives: From ancient methods to today's plastic-wrapped Twinkies Jul 27, 2022
    Show notes

    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? Jul 13, 2022
    Show notes

    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) Jun 29, 2022
    Show notes

    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 Jun 15, 2022
    Show notes

    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. Episode transcripts at acs.org/tinymatters

    The deadly London smog that changed pollution regulation forever Jun 01, 2022
    Show notes

    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.

    Body farms: Anthropological research facilities are teaching us about life after death May 18, 2022
    Show notes

    When it comes to human decomposition, scientists have a pretty good understanding of what happens shortly after you die. But what happens months or years later is mostly a mystery, and that makes it hard for law enforcement to figure out how a person died and, ultimately, provide answers to loved ones of the deceased. That’s where anthropological research facilities (a.k.a. body farms) come in. Links to the Tiny Show & Tell stories here and here. More on the MOVE bombing.

    What happened to Zika virus and the families affected? May 04, 2022
    Show notes

    In 2016, Zika virus dominated the news, but today it seems to have dropped out of public consciousness. Zika is still out there and thousands of children and their families continue to be impacted by its devastating effects. In this episode, you’ll hear from a scientist who's been working with children with congenital Zika syndrome since the start of the outbreak, as well as from a journalist who has spoken with families who are feeling left behind.

    Sugar: The addiction debate and an ancient mutation that’s killing us today Apr 20, 2022
    Show notes

    We humans eat a heck of a lot of sugar. So, how do our bodies process it? And why is eating so much of it so bad? In this episode, we tackle those questions, plus the ‘is sugar addictive?’ debate, and talk about how a DNA mutation that helped our ancestors survive millions of years ago is making life in today’s sugar-saturated world all the more dangerous.

    Bioterrorism: Weaponizing science has been around for centuries Apr 06, 2022
    Show notes

    Science, when it falls into the wrong hands, can do a whole lot more harm than good. This episode is about the historical use of biological agents, the science behind what makes them dangerous, and how researchers are developing drugs to save people who have been exposed to them.

    What is a memory? And how is it stored? Mar 23, 2022
    Show notes

    Have you ever had such a clear memory of something and then found out it never happened? We tend to think of a memory as a photo in an album that we can open up and access whenever we want. But it’s more like the pieces of a photo scattered in a stack of papers and you might only be able to access a couple of those pieces at a time. In this week's episode we're asking, "How do our brains form and store memories? And why do we lose them?" Episode transcripts at acs.org/tinymatters
