Vaccinations, in one form or another, have been around longer than the United States. In fact, during the Revolutionary War in 1776, future first lady Abigail Adams pursued the controversial scientific technique to protect her 5 children against a threat more dangerous than an army of Redcoats. Here’s Luke Quinton with the story.
Cosmic rays from outer space sound like science fiction. They’re not—invisible particles flung from outer space pass through our bodies every minute. But not all cosmic rays are equal; Some are immensely powerful and very rare. For decades scientists have wondered where they're coming from – and what could possibly be hurling them at Earth. Now, they're getting closer to finding out. Ross Chambless has the story.
Every October 16th hundreds of people gather in Dublin to celebrate Ireland's greatest mathematician, William Rowan Hamilton. And get this – It was his act of vandalism on Broom Bridge in 1843 that put him in the history books – it actually changed mathematics forever. Samuel Hanson brings us the story.
Hurricanes Harvey and Irma left devastation in their wake all across the southern United States as unimaginable quantities of water swallowed up small towns and cities alike. But what happens to that water and how can cities better prepare ahead of time? Two years ago, reporter Jenny Chen followed two so-called flood hydrologists to learn more about the preparation.
What if the size of our dinner plate, its color, the material of our cutlery - even background sounds - all affect how our food tastes? In other words, what if it’s not just about what we cooked for dinner, but the context of the meal itself? Reporter Quentin Cooper brings us this story.
Underneath our vrooms, beeps, and rumbles, natural sound may be more important than we think.
On May 2, 2015, beekeepers Pam Arnold and Kristy Allen got hit with a pesticide. They couldn't see it or smell it, but when they saw their bees writhing on the ground and dying they knew something was seriously wrong. They called a panel of scientists at the Minnesota Department of Agriculture.
Thirty-six-year-old twins Carol and Katy are physically identical in every way but one: Katy was born without ovaries, and wanted to start a family. The science and ethics behind ovarian transplants as a treatment for infertility.
The headlines are often full of advice for women about when they should have children. Marnie Chesterton goes digging into the fertility stats and myths for modern women. Prepare to be surprised.
Humans have always been interested in controlling the weather. In the past we used raindances and sacrifices; today we turn to science. Cloud seeding is practiced all over the world, but there's still a lot we don't know about it. Delve into the surprising history, the controversial present, and the uncertain future of cloud seeding.
Visual stylometry is a branch of mathematics that can determine the style of a particular artist’s body of work.

This 1948 graphic shows sound traveling on an axis 700 fathoms down in the Atlantic. Something unusual happens about a half mile under the sea. Ocean physics create a special zone where sound travels for hundreds, even thousands of miles. Whales use it, and cold warriors plumbed its secrets. Listen in: This story was produced by David Schulman in 2014. It was hosted for Transistor by Genevieve Sponsler and mixed for Transistor by Josh Swartz....

Bronwyn Tarr with Carimbó dancers. Oxford evolutionary neuroscientist Bronwyn Tarr was in a remote area of Brazil to begin an experiment. On her first night there, she heard distant drumbeats, went looking for them, and experienced firsthand what she was there to study: how dancing develops a sense of community. This story was produced by Katie Burke in 2015 with the assistance of Jagmeet Mac, and edited by Andrea Mustain. It was hosted for Transistor by Genevieve Sponsler and mixed for Transist...

Ancient navigators traveled across the Pacific without the aid of maps or instruments. We’ll hear from modern-day navigators in New Zealand, Hawai’i and North America about the techniques used to do so. This is the art and science of Polynesian wayfinding, brought to us by producer Lily Bui . This story was produced by Lily Bui in 2015 and edited by Andrea Mustain.

This episode is brought to you by… science fair memories. I ( your host Genevieve ) remember being inspired to create my sixth grade science fair project by a visit to the Franklin Institute in Philadelphia (more on that below). I found this piece from Adam Hochberg in our archive. It’s about schools remaking science fairs to include more actual science and less papier-mâché volcanos. Enjoy! As mentioned in the episode, here’s a photo of my Rube Goldberg machine that I built after seeing Newton’...
Some studies suggest that one out of 10 women in her 30s is peeing herself. Others say the numbers could be much much higher. But it’s tough to talk about. Producer Lauren Whaley shares her story and the scientific approaches to hopefully one day solving this problem.
What’s lost when a song is compressed into an MP3? To the untrained ear, perhaps nothing. But to one composer, these “lost sounds” are a source for his stunning and ghostly musical compositions. This episode was produced by Emily Richardson-Lorente with editing by Andrea Mustain. It was curated and hosted for Transistor by Genevieve Sponsler, and mixed for Transistor by Josh Swartz.
