What if we had the ultimate work-life balance? This fundamental question underlies the hit Apple TV+ show Severance – now in its second season. Ahead of the season 2 finale this Friday, producer Rachel Carlson sat down with the science consultant for the series, Dr. Vijay Agarwal. Vijay says the concept is "resoundingly" possible – and that scientists are closer than we might think.

This past week, the EPA said it is reconsidering the scientific finding that greenhouse gases are a danger to public health. This comes as research shows average global temperatures in 2024 likely rose above a 1.5 degree Celsius threshold that for years has been a red line for climate change.

CrowdScience listener Alina is in a relationship with a polyamorous partner and is very happy with this arrangement, which got her thinking – why is monogamy so often the norm in human societies?

Presenter Caroline Steel goes on an anthropological odyssey to figure out where this drive to find a single partner - and stick with them - comes from.

What can science tell us about how human relationships developed, and whether having one or many partners is more 'natural'?

Evolutionary biologist Kit Opie of the University of Bristol joins us at London Zoo to help us understand the mating systems of our closest primate relatives.

To find out how polygamy developed in some parts of the world we speak to anthropologist Katie Starkweather of the University of Illinois Chicago.

And we learn about the chemistry of bonding from Sarah Blumenthal at Emory University, who explains how the brains of prairie voles may give us clue about the neurochemicals which shape human relationships.

It’s the month of Ramadan, when Muslims across the world fast between dawn and sunset in the belief that it will bring them closer to Allah. And this has inspired the Unexpected Elements team to turn their attention to all things fast.

First, we explore the latest research around intermittent fasting.

Next, we contemplate a new way to relax by harnessing the time-distorting power of black holes.

We then find out why deserts in South Africa are spreading at an alarming rate.

Plus, we’re joined by Dr Claire Lee, a particle physicist who works with the Large Hadron Collider at CERN. She explains how she and her colleagues accelerate particles to phenomenal speeds, how they detect these particles when they collide, and what this can tell us about the origins of the universe.

That, plus many more Unexpected Elements.

Presenters: Marnie Chesterton, with Tristan Ahtone and Leonie Joubert. Producers: William Hornbrook, with Alice Lipscombe-Southwell, Harrison Lewis, Debbie Kilbride and Noa Dowling.

Move over, TikTokers. It's time to shine a spotlight on some of the earliest influencers around: dinosaurs. When these ecosystem engineers were in their heyday, forest canopies were open and seeds were small. But around the time most dinosaurs were wiped out, paleontologists noticed an interesting shift in the fossil record: Seeds got bigger — much bigger. There was a fruit boom. Did the death of these dinosaurs have something to do with it? And who are the modern day equivalent of dinosaur influencers? To find out, host Emily Kwong talks to Chris Doughty, an ecologist at Northern Arizona University.

Five years after the WHO pandemic announcement, an H5N1 call to arms from global health leaders. Also, the oldest western European face is found, the oldest impact crater possibly identified, and strange radio signals from space maybe explained.

Biological sex is all over the news lately. Whether it's via President Trump's executive order affecting passport policy, moving trans inmates between prisons or shifting the requirements for women in sports — appeals to "the biological reality of sex" are constant. In truth, biological sex, like a lot of scientific categories, is nuanced. It's defined by multiple criteria – including chromosomal, chemical and physical factors – that can, and do, change over a person's lifetime. And it's a reality that's definitely not limited to male and female.

In its first 50 days, the Trump administration made sweeping changes to scientific arms of the government like the Department of Health and Human Services, which oversees the National Institutes of Health, Centers for Disease Control and Prevention, and the Food and Drug Administration. The president issued executive orders to terminate all work that was related to DEI, environmental justice and gender inclusivity. In response, research was halted and thousands of people were fired — some of which was reversed. It's a lot to keep track of, so we called in reinforcements. Here to recount it all and analyze what these ongoing changes mean for the future of scientific research in the United States are NPR science correspondents Rob Stein, Pien Huang and Jonathan Lambert.

Tourists to Antarctica are fueling research on some of the tiniest, most influential organisms on Earth: phytoplankton. These itty bitty critters make their own food and are the base of the food web in most of the ocean, but tracking how well they're doing is historically tricky. So, researchers with the program FjordPhyto are using samples collected by these tourists to understand how the balance of power in the Antarctic food web could be shifting — could ripple across the food web of the entire ocean.

This past week, beavers were legally released into the English countryside for the first time since they were hunted into extinction there in the 17th century. Conservationists hailed it as a watershed moment for this keystone species, which helps combat flooding and drought by engineering the landscape with dams and channels.
