Tiny Matters

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 pes...

In this episode of Tiny Show and Tell Us, we talk about the ampullae of Lorenzini that allow sharks to detect the electrochemical signals coming from prey. We also cover the fascinating science behind cyanide-filled clovers. Did you know cyanide is actually a very popular poison in the plant kingdom?

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...

In this episode of Tiny Show and Tell Us, we break down the complicated science of tides and why some places have massive tidal swings while others do not. We also cover the role of ancient viral DNA in our genomes, and how it seems to be making us less responsive to cancer treatments like chemotherapy.We need your stories — they're what make these bonus episodes possible!

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...

In this episode of Tiny Show and Tell Us, we cover work scientists have done to understand what’s going on in dog brains and how attached to us they really are. We also discuss a polymer called hemoglycin that hitches a ride on literal tons of space dust and may have played a big role in how life on Earth got started.We need your stories — they're what make these bonus episodes possible!

*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 we...

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 stori...

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 in...

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. Check out the map in this YouTube short and this Instagram post. We need your stories — they're what make these...

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 m...

Could dark energy be more dynamic than we thought? In this episode of Tiny Show and Tell Us, we cover a recent dark energy discovery that has us contemplating what the end of the universe might look like, and then we delve into if hydrangeas can actually absorb water through their petals (ahem, sepals).We need your stories — they're what make these episodes possible!

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 o...

In this episode of Tiny Show and Tell Us, we cover a recent story about how spending time outdoors can help keep kids from becoming nearsighted and the mysterious absence of skeletons at the site of the Battle of Waterloo despite over 10,000 soldiers dying (and how the beet sugar industry may have played a gruesome role).Here's a link to 'Bones of contention: the industrial exploitation of human bones in the modern age' by Bernard Wilkin and Robin Schäfer.We need your stories — they're what m...

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 develo...
