A poll from the journal Nature found that 75% of researchers in the U.S. are considering leaving the country. That includes a man who’s been dubbed the "Mozart of Math." Stephanie Sy examines what’s behind a potential scientific brain drain. PBS News is supported by - https://www.pbs.org/newshour/about/funders. Hosted on Acast. See acast.com/privacy

Like haunted houses? Scientists do! That’s because they’re an excellent place to study how humans respond to – and even actively seek out – fear. In an immersive threat setting, as opposed to a carefully controlled lab, researchers can learn a lot about what scares people, why and how additional factors (like the presence of friends) might affect our experiences.

So what have they learned? What determines a good scare versus a bad one? And what’s the evolutionary reason for all of this, anyway? In today’s episode, producer Hannah Chinn heads to the haunted house in search of answers.

In the face of floods, wildfires and other natural disasters, when should a community relocate to avoid potential harm? Listener Molly Magid asks that very question. Molly wanted to know how other communities have chosen the path of “managed retreat.” That’s the purposeful and coordinated movement of people and assets out of harm’s way. In today’s episode, Short Wave's Emily Kwong and Hannah Chinn explore cases from New York to Illinois and Alaska to see how successful relocation happens — and what stops it.

People may think of hair loss as a guy thing. But by some estimates, half of all women experience hair loss in their lifetime. And when your social media algorithm gets a whiff? Good. Luck. There are some solutions out there based in science, but not every remedy works for every person — or every type of hair loss. (Yes, there are different types. And the type you have matters!) So today, pharmaceuticals correspondent Sydney Lupkin guest hosts the show to talk about causes of hair loss and how to figure out which treatments may be best for you.

We all know insects are important, but one CrowdScience listener worries that they don’t seem to have equal billing when it comes to human love and attention.

In Scotland’s capital Edinburgh, listener Ruth loves to sit and listen to the birds, the bees and the hoverflies as they go about their daily chores. And it’s got her wondering why bees and butterflies seem to get all the conservation efforts. What do we need to do to protect butterflies as less beautiful caterpillars, and ladybirds as less glamorous larvae? Are people even aware that insects exist in multiple stages of a lifecycle, and that around the world, insect populations are facing perilous levels of decline.

Presenter Alex Lathbridge is on a mission to identify the other unsung insect heroes. Along the way we meet Dr Caitlin Johnstone and Dr Nick Balfour at the Royal Botanic Gardens Edinburgh, who help listener Ruth find out about the lifestyles and lifecycles of hoverflies.

We meet the midge that pollinates cocoa crops in Ghana, as well as Dr Tonya Lander from Oxford University and Dr Acheampong Atta-Boateng from the University of Arizona who have been studying them. And Marc Vaez-Olivera from the company Polyfly introduces us to the billions of hoverflies helping to double avocado yields in Spain.

We also learn what we can all do to help keep insects in our gardens… even if that may involve sacrificing a cabbage or two.

Europe has a new entry/exit system based on biometric data. But what exactly is the science behind biometric data, how can we ensure it’s used responsibly, and can it be cracked?

We also look at how some animals use dung as biometric data with Dr. Adrian Shrader, how your walk can be used to ID you from Professor Mark Nixon, and why gold has its own special measurement. All that plus many more Unexpected Elements.

Presenter: Marnie Chesterton Producers: Margaret Sessa-Hawkins with Lucy Davies and Robbie Wojciechowski

Parasites have roamed the Earth for a long time. They were here before the dinosaurs: The oldest fossils are more than 500 million years old. Today on the show, Regina G. Barber speaks with paleontologists Karma Nanglu and Danielle de Carle about a mysterious fossil called the “Riddler,” and the oldest-ever leech fossil. They share stories of the enduring power of parasitism through the ages and why the clues to prehistoric mysteries may be tucked in a basement.

As two species of coral are killed off by the 2023 heatwave in the Florida reefs, the abilities of different plankton species to cope with rising CO2 remain crucially unknown. Also, retrospective research shows a strong suggestion that mRNA covid vaccination might serendipitously boost certain types of cancer immunotherapy. And, if you can’t identify changing agricultural crop types from satellite observations, why not just strap a camera to your bike helmet?

Around this time of year, every night, a quiet exodus is occurring. Hundreds of millions of birds are migrating thousands of miles south for the winter. One of the biggest dangers for these tiny travelers? Glass. 

Researchers estimate that every year in the U. S., collisions with glass windows take out at least a billion birds. Even if the birds initially fly away, these collisions can cause concussions, broken bones, and other injuries; most victims don’t survive. 

After much reporting, NPR science correspondent Nell Greenfieldboyce has found … it doesn’t have to be this way. Scientists and researchers have studied how to stop collisions from happening, and examples around the country indicate that even little solutions can make a big difference.

Salt marshes exist on every coast of the U.S., but these important wetlands are succumbing quickly to the effects of sea level rise caused by climate change. Grace Go of our journalism training program, PBS News Student Reporting Labs, has the story of how one young photographer from Massachusetts is fighting to protect these places.
