Firefighting is a career with an inherent cancer risk, but a full understanding of what those risks are has been elusive. 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...

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. ...

Medical sculptor Damon Coyle walks around with a Mary Poppins bag of body parts. Fake ones, that is. At the University of Missouri, his lab creates hyperrealistic body parts designed to help medical providers practice for real-world surgeries and procedures. They make things like lifelike arms for practicing blood draws or a set of eyeballs for ocular trauma training. On stage in Columbia, Missour...

Biochemist Kati Karikó spent decades experimenting with mRNA, convinced that she could solve the problems that had kept it from being used as a therapeutic. Her tireless, methodical work was dismissed and she was ridiculed. But that work laid the foundation for the rapid development of COVID-19 vaccines that saved millions of lives, and was recognized by a Nobel Prize in 2023. Kati shares her secr...

Proposed budget cuts for NASA would jeopardize space research. And an executive order could change the political tides for deep sea mining. On May 2, the Trump Administration proposed a 24% budget cut for NASA. It would slash funding for science while setting billions aside for initiatives to send humans to the moon and Mars. New Scientist editor Sophie Bushwick joins us to talk about this, as wel...

Bacteria have been around for billions of years. Could they have come up with complex behaviors that we just don’t understand yet? Could they have their own language? Their own culture? Their own complex societies playing out right under, and in, our noses?  Microbiologist Bonnie Bassler has been studying these questions for more than 30 years. She talks with Host Flora Lichtman about the wild wor...

Millions of years ago, iguanas somehow got from North America to Fiji. Scientists think they made the trip on a raft of fallen vegetation. Also, the marine reptile’s fossilized fetus is cluing paleontologists into the lives of ancient sea creatures. Ancient Iguanas Floated 5,000 Miles Across The Pacific If you picture iguanas, you might imagine them sunbathing on hot sand in the Caribbean or skitt...

In “Into the Unknown,” an astronomer explores the mysteries of the cosmos and the limits of what science can test. What is time? If the universe is expanding, what is it expanding into? What happened just before the Big Bang? Some of the most head-scratching ideas in physics strain the limits of what science can test. In her book Into the Unknown: The Quest to Understand the Mysteries of the Cosmo...

Scientists bring us a lab-grown chicken nugget and texturally accurate, plant-based calamari. We’ll bite. There’s a movement in the world of science to find alternatives to meat and dairy products that don’t involve killing animals. Two avenues for this are by using animal cells in a lab, or going plant-based. Two breakthroughs in this field of food science were published in journals recently: the...

Being able to belt out a tune like Adele or Pavarotti is not just about raw talent. The best singers in the world have to work on their technique—like how to control their breath and develop the stamina to hit note after note for a two-hour concert. But pop stars and opera singers aren’t the only vocalists who have figured out how to harness their voices for maximum impact. Death metal vocalists a...

It’s zombie season! At least if you’re watching the new season of the fungal thriller “The Last of Us,” airing right now on Max, which chronicles what happens after a fungus turns most of humanity into zombies. It’s fiction for us, but for some organisms on the planet, it’s more like a documentary. The fungus that zombifies humanity in the show is based on Ophiocordyceps , a real fungal group that...

Research suggests that better understanding the psychological and neurological components of chronic pain may lead to better treatments. Chronic pain is remarkably common: Roughly 20% of adults in the US live with it. And people with chronic pain are more likely to have depression, anxiety, and substance abuse disorders. But this relationship between physical and mental health is not as straightfo...

Researchers isolated one kind of cone in the eye and aimed lasers at it to allow subjects to see a super vibrant teal shade they call “olo.”Think about the colors of the world around you—the blue of a cloudless sky, the green of a new leaf, the blazing red of a tulip’s petals. We see these colors because of the way our eyes work. But what if we could change how our eyes respond to light, and prese...

How will market uncertainty and a lack of federal support for climate efforts affect the future of clean energy in the United States?
