Attracting Birds To Prime Habitat By Playing Recordings Of Their Calls

How do you know a restaurant is good? If the parking lot is full of cars, that’s a pretty good indication. If it’s empty, you probably won’t bother stopping.

In this case, the restaurant is a newly restored wetland in Michigan and the customers are rails. The birds migrate at night, so if they don’t hear other rail calls in an area, they’re not likely to stop. Researcher Dustin Brewer is broadcasting recorded rail calls to try to bring the secretive birds to prime habitat—to feed and mate. Rails are declining, mostly due to habitat loss. Experts say if rails are influenced by these recordings, it could help increase the bird’s population.

Collars, Cameras, And Carcasses: Studying Urban Wildlife

When you hear the words “urban wildlife,” you might think of rats scampering across a street, pigeons plopped on railings, or crows fighting over a pizza crust. But urban wildlife are so much cooler and more diverse than they get credit for, and scientists have a lot to learn from them. In the blink of an evolutionary eye, urban wildlife have quickly adapted to changing landscapes and learned to take advantage of sprawling urban areas.

Guest Roxanne Khamsi speaks with Dr. Chris Schell, an assistant professor studying urban ecology at the University of California, Berkeley. They chat about why urban wildlife is so cool, how scientists can study them, and what we can learn from our scrappy neighbors.

A New Lyme Disease Test In Development May Help Improve Treatment

Roughly 476,000 people in the United States are diagnosed and treated for Lyme disease each year, according to Centers for Disease Control and Prevention (CDC) estimates. However, the CDC says that this number is likely an overcount because many patients receive treatment based on symptoms without a positive test result.

On top of that, there are some limitations of the diagnostic tests available for Lyme disease. The FDA-approved Lyme disease tests can only determine if a patient has had Lyme disease in the past, not if they currently have an infection. The test cannot determine if antibiotic treatment was successful, or if a positive test result is due to a re-infection.

Guest host Roxanne Khamsi talks with Pete Gwynne, a molecular and microbiologist at the Tufts Lyme Disease Initiative, who is working to solve some of these problems by developing a new diagnostic test for Lyme disease.

‘I Will Not Be Vole Girl’—A Biologist Warms To Rodents

The path to becoming a scientist is not unlike the scientific process itself: Filled with dead ends, detours, and bumps along the way.

Danielle Lee started asking questions about animal behavior when she was a kid. She originally wanted to become a veterinarian. But after being rejected from veterinary school, she found a fulfilling career as a biologist, doing the type of work she always wanted to do—but never knew was possible for her.

Science Friday producer Shoshannah Buxbaum talks with Dr. Danielle Lee, a biologist, outreach scientist, and assistant professor in biology at Southern Illinois University about what keeps her asking questions, what rodents can help us understand about humans, and the importance of increasing diversity in science.
