In this episode of Tiny Show and Tell Us, we cover a study where a researcher stepped on 116 snakes over 40,000 times for science (don’t worry, the ‘steps’ were more like touches, no snakes were harmed in the process). Then we get into why a pollen allergy might trigger an allergy to some of your favorite fruits.

Dominique Jean Larrey lived quite a life. He was born in 1766, and at the age of 13, had to walk from his home in a French village to study in the city of Toulouse. That journey was 70 miles, and yes, he walked it. That would be important much later in his life, when he found himself walking through the bitter cold in Russia as the Chief Surgeon of Napoleon's army. During that time, Napoleon's troops had to contend with the reality of Russian cold and temperatures that got as low as -37 degrees Celsius, which is about -35 Fahrenheit.
Larrey attributed his ability to withstand the cold to his walking. But many of the soldiers around him wound up with frostbite, and to treat them, Larrey suggested slowly rewarming the affected area and rubbing it with snow. Frostbite treatment has been on quite the journey since then, and it was just earlier this year that the FDA approved the first drug to treat frostbite in the US, which is exciting news for the doctors who see cases of frostbite and for patients who are often left with the horrific reality of amputation.

In this episode of Tiny Show and Tell Us, we cover exciting new 'living robots' called xenobots — made from frog cells with the help of a supercomputer — and what they might be used for down the road. Then we challenge how much "junk" really makes up "junk DNA" and discuss the regulatory sequences and other things our DNA codes for that aren't functional proteins.

On Tiny Matters we just weren’t giving enough love to plants, but we’re dedicated to fixing that! In this week’s episode, we chat with Matt Candeias, the host of the podcast In Defense of Plants. We tackle a subject that we had definitely oversimplified in our minds: pollination. From stinky corpse flowers to pitfall traps to faux fermentation, the way plants have evolved so many strategies to reproduce is beyond fascinating. We can’t wait to take you all on this pollination ride!

In this episode of Tiny Show and Tell Us, we cover why your body feels so ‘off’ at high altitudes and how we’ve evolved not to detect low oxygen levels but high amounts of carbon dioxide. Then we unpack the confusing world of molecule chirality — what it is, why it matters, and how we evolved to only have ‘left-handed’ amino acids but ‘right-handed’ DNA and RNA.

How often do you think about your teeth? In this episode of Tiny Matters, we talk about how the atoms trapped within teeth can reveal what an animal ate and where it lived, and how studying teeth has helped ecologists reconstruct prehistoric food webs of megatooth sharks and retrace the steps of woolly mammoths across the Arctic. And hopefully, we’ll give you a few new reasons to appreciate your own pearly whites.

In this episode of Tiny Show and Tell Us, we explore the science behind a very catchy headline about a drug that makes mice look more youthful and increases their life expectancies. Then we shift gears to talk about a predatory unicellular organism with a swan-like neck that rapidly extends a great distance to capture prey. Researchers used origami to understand the mechanics behind this anatomical feat.

Halloween is right around the corner, so what better way to celebrate than a deep dive into the ‘science’ of ghost sightings? We touch on a bit of the psychology behind these experiences and then break down the equipment people use when searching for proof that spirits float among us, and how power lines and rats in walls muddy the specter detection waters. Then we switch to something a little more corporeal, but no less weird: cyborgs. Biohybrid robots hold a lot of potential, but their ethical use, especially when human tissues are involved, need to be carefully considered.

On January 27, 1958, newspaper editor Olga Huckins sat down to write an angry letter to a friend. Olga and her husband owned a private two-acre bird sanctuary, and the previous summer the government had sprayed the pesticide DDT all over that two acres to control the mosquitos. She saw wildlife, particularly birds, getting sick and dying. The friend Olga sent the letter to was none other than Rachel Carson, who would go on to write the book Silent Spring, exposing the dangers of synthetic pesticides, including DDT, and helping push forward the modern environmental movement and the creation of the US Environmental Protection Agency.
Today on the show we’re going to talk about the history of pesticides and their deployment, and how researchers are working to develop more effective, safer pesticides. We will also take a fascinating dive into the coevolution of plants and pests, specifically insects, and what we’re learning about the effectiveness of pesticides based on hundreds of millions of years of plant and insect evolution.

E-cigarettes, commonly referred to as “vapes,” were invented in the early 2000s with the explicit goal of helping people quit smoking by transitioning them to something safer. But there are many people, particularly in the United States, who start vaping without ever having smoked a cigarette, leading to fears that vaping will be an on-ramp to smoking — a “gateway drug.” In fact, in the U.S. alone, nearly half a million middle school students vape. And in 2019, the CDC started receiving reports of severe and acute lung injury in people who vaped. By February of 2020, almost 3,000 people had been hospitalized and 68 people had died.
We know that smoking is deadly (in fact, it’s estimated to take about 10 years off your life), but of course vaping isn’t risk free. In this episode of Tiny Matters, we’ll dive into the science behind both to answer, “What’s more dangerous, smoking or vaping?” “And does vaping actually help people quit smoking cigarettes?” We’ll also get to the bottom of why so many people got sick or died from vaping back in 2019 and 2020, yet we haven’t seen injuries like that since.

Around 8 million years ago, an underwater volcano just to the east of Madagascar formed the island of Mauritius. Pigeons on nearby islands set flight and settled on that island. There they continued to evolve, and the dodo bird eventually emerged as its own species: Raphus cucullatus. And tiny Mauritius, with an area of just 720 square miles, was the only place in the entire world where the dodo lived. And it lived a good life, among bats and tortoises and other birds, safe from the predators its ancestors left back on land millions of years before. But in 1598, when sailors from the Netherlands arrived, the dodo’s luck ran out.
On today's Tiny Matters we dive into the history of the bird that everyone loves to make fun of: the dodo. And we’re going to explore some of the work investigating why this bird went extinct and what it was like when it was alive. Then we’ll shift gears and talk about what some people worry will cause a massive extinction in the future — one that might include us: supervolcanoes. These are volcanoes capable of eruptions thousands of times larger than the volcanic eruptions we are most familiar with today. The recent volcanic eruptions in Iceland or the deadly Mount St. Helens eruption in 1980 pale in comparison. These are volcanoes bigger than anything we've experienced as human beings in our recorded history. So are we ready if one comes our way?

*A disclaimer that there will be discussions of self harm in this episode* In 2003, Chris Nowinski found himself in a WWE wrestling ring, concussed and not remembering where he was or how he was supposed to finish the match. This would be a pivotal moment not just in his life but for an entire field of research on a neurodegenerative disease long known to exist but poorly defined and even censored: chronic traumatic encephalopathy or CTE.
There’s evidence that people knew about CTE — which went by names like “punch drunk” — starting in the 1920s, but it wasn’t until the 2000s, when American football players began being diagnosed with CTE post-mortem, that the disease started gaining public traction. Many of those football players, including Andre Waters, had died by suicide. Chris, now a behavioral neuroscientist and the co-founder and CEO of the Concussion Legacy Foundation, pushed to get the brains of Waters and other athletes tested, and began spreading awareness and putting pressure on organizations like the NFL to acknowledge the devastation this disease can bring to athletes and their families.
Today on the show we will cover what’s known about CTE and how to prevent it, and how researchers are trying to find ways of diagnosing it in people who are still alive and working to find treatments.
Here are some good CTE resources:

In the early hours of January 7, 2022, David Bennett was out of options. At just 57 years old, he was bedridden, on life support, and in desperate need of a heart transplant for which he was ineligible. Yet Bennett would go on to live for two more months — not with a human heart, but with a heart from a pig. David Bennett was the first case of a pig heart being transplanted into a human, an example of xenotransplantation — when the cells, tissues or organs from one species are transplanted into another. In the United States, over 100,000 kids and adults are currently on the national transplant waiting list, and every day around 17 people on that list die while waiting.
In today's episode, we cover the science and historical research that made Bennett’s transplant possible, and what doctors learned from him that helped the next heart xenotransplant recipient, Lawrence Faucette, live even longer. We also get into some of the ethics conversations surrounding xenotransplantation work — not just questions about the use of animals like pigs and baboons, but experiments with recently deceased, i.e. brain dead, people.

You might be familiar with plant-based alternatives to animal products — things like the Impossible Burger or Beyond Meat. And maybe you’ve heard of places trying to grow fish or meat cells in a dish to make sushi or steak without a fish or cow. But in today’s episode we’ll cover an old technology that’s bringing us some new foods: precision fermentation. With precision fermentation, many everyday products including dairy-free milk, insulin, and the collagen in lotions are now being made by microbes. How did we turn microbes into teeny tiny production factories for so many different products, and where’s the limit when it comes to what we can use them to create?
In this episode we’ll demystify the science behind this technology and its history. We’ll also dive into how public perception influences the success of new food technologies and how framing can change minds and reduce both misinformation and skepticism.
