Tiny Matters

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.

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.

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.

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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?"

Typhoid fever is a disease that, in the United States, is synonymous with Mary Mallon—a woman better known as Typhoid Mary, who infected New Yorkers with typhoid in the early 1900s. But typhoid is not just a thing of the past. Across the globe every single year, it kills over 100,000 people. And over the last few years, even in countries like the US where typhoid hasn’t been a concern for generations, the number of reported cases is climbing. So why is typhoid making a comeback? And what are scientists doing to stop it?

Pollution, disease, and climate change are pushing the limits of what coral reefs can withstand. But, despite those harsh conditions, some corals are thriving. Scientists are trying to understand how that's possible, and what they're learning could save these incredible ecosystems from extinction.

We had a vaccine for COVID-19 within a year of identifying the virus that causes it, yet still don’t have one for HIV after 40 years of research. Why is that? On this week’s episode, Sam and Deboki cover HIV’s history and spread, how it causes AIDS, and the tiny things it does that have allowed it to evade potential vaccines for decades.

This week on Tiny Matters, we’re talking about dinosaurs: the ancient beasts that died off 65 million years ago but whose remains still captivate us today. Fossils are helping scientists piece together how dinos and other extinct creatures looked and behaved. That info isn’t just inspiring movies like Jurassic Park—it’s helping researchers predict Earth’s future and could even lead to more sustainable tech.

Tiny Matters is a science podcast about things small in size but big in impact. Every other Wednesday, join hosts Sam Jones and Deboki Chakravarti as they unpack the little stuff that makes the big stuff in our world — both good and bad — possible, tackling questions like, “What is a memory?” "Is sugar actually addictive?" and "Why don't we have an HIV vaccine?"See Privacy Policy at https://art19.com/privacy and California Privacy Notice at https://art19.com/privacy#do-not-sell-my-info.
