Take a dive into the genes, microbes, molecules and other tiny things that have a big impact on our world with Tiny Matters. Join scientists Sam Jones and Deboki Chakravarti as they take apart complex and contentious topics in science and help rebuild your understanding. From deadly diseases to ancient sewers to forensic toxicology, Sam and Deboki embrace the awe and messiness of science and its place in the past, present, and future. Tiny Matters releases new episodes every Wednesday and is brought to you by the American Chemical Society, a non-profit scientific organization advancing chemistry and connecting the broader scientific community. Tiny Matters is produced by Multitude.
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 ...
In this episode of Tiny Show and Tell Us, we hear from a listener about her incredible grandma who’s a pharmacist in Venezuela (still, at 92 years old!) and has inspired her love of science and current lab work. We then talk about orcas spotted wearing dead salmon as hats, and what this fishy behavior may mean.

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 a...
In this episode of Tiny Show and Tell Us, we discuss the differences between e-cigarettes (vapes) and far-less-studied dry herb vaporizers. Then we talk about some of the incredible evolutionary adaptations of populations of people living at high altitudes.

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 consequen...
In this episode of Tiny Show and Tell Us, we discuss if a crocheted wasp nest could actually attract wasps and keep them from invading your property. Then we talk about how sewage is impacting the resilience of coral reefs.

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 serious...
In this episode of Tiny Show and Tell Us, we cover the science of rainbows and why double rainbows are always mirror images. Then we talk about mysterious, yet super common, chromosomes called Robertsonian chromosomes that seem to have a significant impact on human health.

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...
In this episode of Tiny Show and Tell Us, we cover the incredible world of fungus farming ants and how it really needs to be a Pixar movie. Then we talk about what makes fresh squeezed juice taste so much better than the mass produced processed juices you pick up in the grocery store.

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...
In this episode of Tiny Show and Tell Us, we consider if bacteriophages could become our biggest allies in the fight against antibiotic resistance. Then we cover the historical role of "night soil men" and how some sewage treatment systems today are setting the standard for sustainable management of human excrement while also making sure we don't get sick.

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 sci...
In this episode of Tiny Show and Tell Us, we cover a species of armadillo that, as it turns out, is actually four species. Then we discuss what researchers know about if pregnant people have a better sense of smell.

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 i...

In this episode of Tiny Show and Tell Us, we cover an aurora-like phenomenon — STEVE (Strong Thermal Emission Velocity Enhancement) — and how citizen science led to its discovery and unforgettable name. Then we talk about convergent evolution in tenrecs, a fascinating family of animals endemic to Madagascar. Some look identical to hedgehogs, some are similar to opossums, and others look like moles.

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 t...

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.
