1048: Turning The Binoculars On Birders 03.06.2025

Birding is a hobby that attracts a very particular group of people: the kind who get up at sunrise, go into the woods, and wait for hours for a little tiny feathered friend to fly past. Author and illustrator Rosemary Mosco guides us into the world of birding with her new book, The Birding Dictionary . Plus, biologist Sara Lipshutz fills us in on the surprisingly high-drama world of some female bi...

And, the FDA has cleared a blood test to help diagnose Alzheimer’s disease....

1039: What Happens When Air Traffic Control Systems Go Dark? 29.05.2025

At the end of April, air traffic control radar surveillance and radio communication systems at Newark airport went dark for over a minute. A week and half later, radar went down again briefly.

How do air traffic controllers keep track of all of...

1038: Could The NIH Plan For A ‘Universal Vaccine’ Really Work? 28.05.2025

At the beginning of May, the National Institutes of Health, part of the Department of Health and Human Services, announced a plan to develop a universal vaccine platform.

But will it work? And where does the science...

1037: The Leap: This Is Going To Kill Your Career 27.05.2025

Betül Kaçar started her scientific career as a biochemist, working on an enzyme found in zebrafish.

Shukla became a pioneer in modern weather forecasting , and he tells his unlikely story in his new memoir, A...

1034: Are Physical Buttons And Knobs Making A Comeback? 21.05.2025

In recent years, digital touchscreens have replaced many of the buttons and knobs that control various functions in cars.

1033: Scientists Identify Genes For Tomato And Eggplant Size 20.05.2025

Tomatoes come in all kinds of colors, sizes, and flavors. But what’s going on at the genetic level? What makes a tomato red or yellow? Tiny or giant? Researchers are mapping the genomes of 22 varieties of nightshades—the family of plants that includes tomatoes, potatoes, and eggplants. They located the genes that control the size of tomatoes and eggplants and then used CRISPR gene editing to grow...

An important registry designed to help understand the link between firefighters and cancer was taken offline on April 1 because of federal cuts, then restored six weeks later. Host Flora Lichtman discusses this with firefighter health researcher Sara Jahnke and reporter Murphy...

1029: Identifying New Plants, And The Scientific Secrets Of Superfoods 14.05.2025

What does it take to create and maintain one of the largest repositories of botanical information in the world? For starters, it can mean helicopter-ing into remote nooks of the Amazon, hiking through rough terrain, looking for strange fruits and flowers, and climbing trees to pluck specimens from the branches. Then there’s all the science required to identify, classify, and codify those species. ...
