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.

The opening ceremony of the 2024 Summer Olympics is two short days away. As over 10,000 athletes gather in Paris, France, anticipation builds. But that anticipation is not just for the next 19 days of fierce competition, it’s also for the Seine. The Seine River is set to host events including the 10 kilometer marathon swim and the triathlon, but as the Games approached, much of the testing showed that the Seine was still teeming with dangerous levels of E. coli and other bacteria. And a lot of people are asking, "why is this river so dirty?" In today’s episode, we’re going to get into the interesting history of how people have dealt with sewage, from Mesopotamia times to today, and how the Seine, as well as a river Sam knows well — the Potomac — are trying to clean up their acts. We'll dive into questions like, 'Will it ever be legal to swim in the Potomac?' 'Did Thomas Crapper actually invent the cra... um, toilet?' 'How do you clean up dilapidated old mines that are poisoning a river?' and more.

This summer is a sports fan’s dream! Beyond some major soccer tournaments, Paris 2024 kicks off at the end of July. If you think about it, sports are science in motion, which means that buried in incredible athletic feats is a lot of data about how athlete bodies are using and responding to chemistry, biology and physics. That data is helping scientists design new or better tools for athletes.
Today, in honor of this very sporty summer, Sam and Deboki delve into how scientists go about developing the equipment that helps move athletes, and how that equipment is holding importance for the medical field as well, for instance in diagnosing cystic fibrosis in infants. Sam and Deboki will also cover the creative experiments one scientist did to design a better bike saddle for female pro cyclists, who endured decades of intense injuries that ultimately required many to undergo labiaplasties, until American racing cyclist Alison Tetrick came along and said “enough is enough.” Title IX may have revolutionized female sports participation, but until more recently building gender-specific sports equipment from the ground up was unheard of.

Standard reference materials — or SRMs — at the National Institute of Standards and Technology (NIST) serve as standards for many food, beverage, health, industrial and other products. There are over a thousand SRMs including peanut butter, house dust, dry cat food, soy milk, blueberries, stainless steel, fertilizer, and a DNA profiling standard. SRMs help make products safer and ensure that consumers are getting what they think they’re getting. But how do they work exactly?
In this episode of Tiny Matters, Sam and Deboki cover SRMs that are helping us accurately detect toxic substances like lead and pesticides in our house dust, fight seafood fraud, and keep PFAS out of our meat. Sam also travels to the NIST headquarters outside of Washington, DC to get a behind the scenes tour of how SRMs are made. She even gets a chance to snoop around the warehouse where SRMs are stored.Email us your science stories/factoids/news that you want to share at [email protected] for a chance to be featured on Tiny Show and Tell Us!

At the end of 2016, a pilot reported that a volcano in Alaska called Bogoslof was erupting. Bogoslof had been quiet for 24 years, and there wasn’t any equipment on it that scientists could use to track its eruptions. But over the next 8 months, scientists were able to track at least 70 eruptions from Bogoslof, and they did so using something you might not expect: sound.
In this episode of Tiny Matters, we’ll cover what sound can tell us about events as big as volcanoes and ‘Swiftquakes’ and as small as the insect world, where researchers are using AI to track different insect species, leading to important discoveries that could help not just public health but agriculture and climate policy.

On March 11, 2020, after over 118,000 cases of COVID-19 had been reported in 114 countries, the World Health Organization declared COVID-19 a pandemic. The term Long COVID began popping up across the globe shortly after. People with Long COVID experience any combination of a huge number of symptoms that range from gastrointestinal issues to brain fog to extreme exhaustion and an inability to do what were once pretty simple tasks like getting dressed, preparing meals, or even getting out of bed.
https://www.covid.gov/be-informed/longcovidhttps://solvecfs.org/solve-long-covid/long-covid-resources/https://www.bu.edu/ceid/training-education/long-covid-resources/https://longcovidalliance.org/
Although we have a ways to go before we understand a disease as complex as Long COVID, over the last few years scientists have made significant research strides and the millions of people suffering from Long COVID have brought light to health conditions including ME/CFS, that many people didn’t previously realize existed. In this episode, you’ll hear from an ME/CFS researcher, a Long COVID patient about her difficult and winding experience to understand what was happening in her body following a COVID infection, and a journalist and author who recently wrote a book on Long COVID.

A week ago, the Metropolitan Museum of Art held its 2024 Met Gala — a yearly event to raise money for the Costume Institute. The gala also marks the opening of the Costume Institute's annual show, which this year is called "Sleeping Beauties: Reawakening Fashion." The idea behind this exhibit is to showcase pieces from the museum's collection that are too delicate to show on mannequins. Instead, the exhibit will feature recreations of the pieces using AI and 3-D techniques, along with sound and smell. But what about textiles that museums choose to display — how is science used to maintain these incredible, often fragile, pieces of the past?
In this episode of Tiny Matters, Sam and Deboki cover the fascinating textile landscape, from plant-based fibers to the evolution of modern synthetic materials and the investigative approaches used to preserve not just these fabrics but also the stories they tell and the cultural significance they hold.

Every year, tuberculosis claims over a million lives despite being curable. Tuberculosis or TB is an infectious disease caused by Mycobacterium tuberculosis. About 5–10% of people infected with TB will eventually get symptoms. In the early stages a TB infection might cause chest pain, a cough, night sweats, and loss of appetite. But eventually it could create holes in the lungs and cause you to cough up blood. And of course, TB can be deadly.
In this episode of Tiny Matters, Sam and Deboki talk with TB researcher Uzma Khan as well as John Green, the author of books including The Anthropocene Reviewed, Paper Towns, The Fault in Our Stars, and Turtles All the Way Down. John is also the co-creator of Crash Course and one half of the vlogbrothers — the other half being his brother Hank Green, who Deboki and Sam chatted with on the show last year.
Although he's best known as an author and YouTuber, last summer John made headlines for something else: fighting for more equitable access to tuberculosis treatments, particularly bedaquiline, an incredibly effective and essential medicine for patients with drug-resistant tuberculosis.
In this episode, Sam and Deboki cover the science and history of this devastating yet treatable disease, the recent public pressure on companies that is leading to increased treatment and testing access, and clinical trials that make John and Uzma hopeful that one day this humanity-plaguing disease could be gone.
