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.Tell us what other tales of dino past you want us to regale you with by emailing us at shortwave@npr.org!

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.Want the episode to cover more nuances of human biology? Let us know by emailing shortwave@npr.org!

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.
