In 1975, NASA launched two spacecraft to Mars. Viking 1 and Viking 2 arrived at their destination less than a year later, each bringing a lander to explore the surface of the planet and an orbiter to survey above. What was supposed to be a 90 day mission ended up lasting until the early 1980s. Those years provided scientists with important data about the Martian landscape, from seismometer readings of marsquakes to the reddish color of the sky.But the Viking missions had another important task: they were going to look for possible signs of life. The Viking experiments would go on to become an important landmark in science, one that's helped researchers in a number of fields figure out what we can be doing better to find signs of life beyond Earth.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

In this episode of Tiny Show and Tell Us, we talk about what dark energy and dark matter are made out of and how knowing more could upend our understanding of the Big Bang. Then we cover microchimeric cells — cells transferred between baby and mom — and how new research in mice shows that fetal cells that took residency in mom from a first pregnancy are replaced by new fetal cells of a second pregnancy.We need your stories — they're what make these bonus episodes possible!

In December 2017, the FDA approved a new injectable drug to treat type 2 diabetes called semaglutide, which you likely know by its brand name: Ozempic. A few years later, during the pandemic, Wegovy, a drug with a higher dose of the same active ingredient, was approved specifically for chronic weight management. Soon after, people taking Ozempic started reporting a dramatic, even “life-changing” weight loss. Ozempic is now a bona fide blockbuster. So what's the science behind these “wonder drugs” that apparently 1 in 10 of us could end up using? They have the potential to have so many positive effects on our lives, from treating Alzheimer's disease and addiction to changing our relationship with consumption but, like with most things, they also come with risks.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

Over the last 200 years or so, vaccines have come a long way, for a number of viruses. We've made so much progress, in fact, that in 2017 scientists began the early stages of vaccine development for some virus families they believed could pose a future pandemic threat. One of those families was Coronaviridae: coronaviruses. Not many people know that before SARS-CoV-2 started making its way into people in 2019, there was already a project underway in the U.S. to create a vaccine for a looming coronavirus (we didn't!), but even that would not have been possible without the decades of vaccine and drug research that came before it, particularly for HIV.

The placenta is essential for life, but so much of its function is unknown. In this episode, we talk about how this disposable organ's development within the early weeks of pregnancy shapes so much of what happens months later. We tackle what makes the human placenta so unique, what other animals like reptiles are teaching us about it, and how scientists are turning to evolution and computer models to see if we can better understand it.Check out the IVF episode of Tiny Matters.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

The reason many of us hear about glaciers has to do with sea level rise — which makes sense! If all of the glaciers on Earth melted, sea levels are predicted to increase by about 230 feet (70 meters), which would flood coastal areas, envelope a number of islands, and seriously impact human infrastructure, including our current water resources. But glaciers do more than safeguard Earth's future — buried within them is our ancient past. In January of this year, a team of scientists drilled nearly 2 miles down into an Antarctic glacier. The 1.7 mile long cylinder of ice they pulled up, called an ice core, holds the equivalent of 1.2 million years of climate history. In this episode of Tiny Matters, we talk about what glaciers mean to us today, their importance for the future of our planet, and what they tell us about Earth's ancient past.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

In the 1700s and early 1800s scientists from Europe and the Americas were studying what they called "race science," a pseudoscientific field of study promoting the idea that humans could be divided into separate and unequal races. Biases stemming from race science have influenced medicine for hundreds of years, and still have deadly consequences today. In this episode of Tiny Matters, we tackle some of these consequences, where they get their roots, and what people like our guest — physician and science communicator Joel Bervell — are doing to raise awareness and incite change.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

In the 1970s, the rape kit began as a simple box with some envelopes, a comb, nail clippers, and a few other basic tools. The contents of the kit have evolved somewhat since then, but the technology to analyze samples has evolved astronomically. And, through and through, the rape kit has stood for the idea that every survivor has the right to go to a hospital, get a full forensic exam, and have their evidence taken seriously. On today's episode, we talk about how the rape kit became a reality and the woman who championed the rape kit into the tool it is today. We also discuss what the future of the rape kit could look like, how the rape kit backlog has grown of control in some states, and what activists are doing about it.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

Hemophilia is a rare bleeding disorder caused by a deficiency in clotting factors in the blood, which can cause permanent damage to joints and, in some cases, life threatening bleeding, both externally and internally. Today, people with hemophilia can live generally long, healthy lives, but in previous generations, the future wasn't so bright. In fact, less than a century ago the life expectancy for someone with hemophilia hovered around just 10 years. It doesn't receive much attention, and when it does, what you hear might not be all that accurate. In today's episode, we cover the history of hemophilia and the science behind treatments over the decades, including the devastating impact of the HIV/AIDS epidemic on hemophilia patients. We'll also clear up several misconceptions, including one that seems to show up a lot in popular culture: that hemophilia is a "royal disease.” Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

In the summer of 2011, paleontologist and science writer Riley Black was on a mission. Walking through the Montana desert, she was on the lookout for a Tyrannosaurus rex. But that day, she wasn't having any luck. Sitting atop a rock, she pulled out a geological hammer, sometimes called a rock pick, to dislodge a little piece and try to discern its composition. What she saw was a leaf, but upon closer inspection realized it was in fact the fossil of a leaf. As it turned out, finding it likely provided so much more information than if she had come across the dinosaur. In this episode of Tiny Matters, we explore the complex and essential relationship between plants and animals across evolution and some of the pivotal moments that allowed humans to exist and that led to the world we live in today.

In 1893, Belgian paleontologist Louis Dollo suggested that evolution can't go backwards in the exact same way that it proceeded. This became known as “Dollo's Law,” and came under a lot of scrutiny. But, more recently, Dollo's Law was co-opted into the idea that traits, once they gain a certain amount of complexity, can't return to a simpler state. In this episode of Tiny Matters, we explore two exciting examples where scientists have found that not to be the case. Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

The 1940s were a pivotal time for the world. In the United States, as men went to fight in World War II, women became essential additions to the US workforce. And when the war ended, many of those women wanted to continue working. But having more children than they wanted or could care for was a huge barrier to making that a reality. When the oral birth control pill became available in 1960, it was a massive deal because it gave women control over when and if they wanted to have children. Today the pill is widely accepted, comes in a number of formulations, and is considered so safe that now you can buy it over the counter. But setting the groundwork for what we have available today took time, and experimentation. The history of the pill was also shaped by racism in an era where discrimination was not just state-sanctioned, but backed by many scientific institutions. In this episode of Tiny Matters, we cover the science and development of the oral birth control pill and, importantly, the lack of ethics in its testing, particularly in the trials that began in Puerto Rico in 1955.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

On April 26, 1986, the Soviet Union's Chornobyl Power Complex nuclear reactor 4 exploded, releasing a massive amount of highly radioactive material. People living near the power plant were forced to evacuate, and the area was deemed uninhabitable. But today, many animals — some the descendants of pets left behind — have made this region their home. In this episode, we chat with researchers who have spent a lot of time in the Chornobyl Exclusion Zone studying the animals that live there, trying to understand how constant low levels of radiation impact their health. What they're learning could inform plans to repopulate areas that suffered past nuclear disasters, including Fukushima, and help with the development of methods that protect astronauts from radioactivity in space.

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. Send us your science stories/factoids/news for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode and to be entered to win a Tiny Matters coffee mug!

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.

*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:https://concussionfoundation.org/CTE-resources/support https://www.bu.edu/cte/resources/resources-for-families/Send us your science stories/factoids/news for a chance to be featured on an upcoming Tiny Show and Tell Us episode and to be entered to win a Tiny Matters coffee mug!

In this episode of Tiny Show and Tell Us, we cover neurogenesis in adulthood (yes! your brain can make new neurons even as you age), the link between exercise and increased neurogenesis in the hippocampus, and the implications that could have for neurodegenerative diseases like Alzheimer's. We continue on our brain-focused episode with the role cerebrospinal fluid plays in cleaning out your brain while you sleep and how its movement is in fact influenced by your brain waves.We need your stories — they're what make these bonus episodes possible!

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.Check out Jyoti Madhusoodanan's Undark story, "The Allure and Dangers of Experimenting With Brain-Dead Bodies" here.

In this episode of Tiny Show and Tell Us, we cover the recent discovery of a new (relatively speaking, more like 100 million year old) organelle called a nitroplast that could revolutionize agriculture. Then we embark on a highly entertaining journey of 1930s chemistry poetry, sometimes written by inebriated chemists, and track down a rare and stunning Chemical Map of North America.

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.Send us your science stories/factoids/news here for a chance to be featured on an upcoming Tiny Show and Tell Us episode and to be entered to win a Tiny Matters coffee mug!Subscribe to our newsletter at bit.ly/tinymattersnewsletterLinks to the Tiny Show & Tell stories are here and here.

Send us a Text Message.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.

Send us a Text Message.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.Email us your science stories/factoids/news at tinymatters@acs.org for a chance to be featured on an upcoming Tiny Show and Tell Us episode!Subscribe to our newsletter at bit.ly/tinymattersnewsletterLinks to the Tiny Show & Tell stories are here and here.
