Primate Parasites, Spider Mating Songs, Spotted Lanternfly. Oct 1, 2021, Part 1

The World According to Sound Podcast
Spiders aren't powerful enough to vibrate the air and actually sing. Male spiders send vibrations down their legs and into whatever they're standing on. Nearby females hear the song vibrating up their legs. We're only able to hear these spiders because of a lazer vibrometer, which records their tiny vibrations. The world according to sound is hosting this winter's 80 minute by noral events.
Healthcare Is Hard Enough to Get. If You’re A Trans Youth, It’s Even Harder
Healthcare can be difficult to access for anyone—that’s been made clear during the COVID-19 pandemic. But for transgender youth, the barriers are exponentially higher. A new study from the journal JAMA Pediatrics shows that trans youth don’t get the care they need because of a variety of obstacles. Those range from laws that prevent them from advocating for themselves, to stigma from doctors.
Joining Ira to talk about this story and other big science news of the week is Sabrina Imbler, science reporting fellow for the New York Times based in New York City. Ira and Sabrina also discuss the massive undertaking of COVID-19 testing in school districts, and the impacts ivermectin misinformation is having on the livestock and veterinary industries.
See A Spotted Lanternfly? Squash It!
If you live in Pennsylvania or any of its surrounding environs, you’ve probably seen a really interesting looking bug in the past few years: the spotted lanternfly. Around this time of year, it’s in its nymph stage. But when fully grown, these lanternflies sound a little like the joke—they’re black and white and red all over. They’ve also got spots, as their name suggests.
The charming news about how interesting they look is offset by the bad news: They are an invasive species. And they frighten crop farmers because they have a taste for just about anything, and a fondness for grapes, which could have dramatic economic consequences.
Many states have a unified stance on what to do if you spy a spotted lanternfly—stomp them out. But is that an effective way to stop their spread? Joining Ira to chat about stomping techniques and lanternfly biology is Julie Urban, associate research professor in entomology at Penn State University, in State College, Pennsylvania.
As Primates Go Extinct, So Do Their Parasites, Upsetting Ecosystems
As of 2017, more than half of primate species—that’s apes, monkeys, lemurs, and our other relatives—were considered at risk of extinction. While the loss of these animals would be its own ecological crisis, this is causing another wave of die offs: the parasites that live on those primates, many of whom are specially adapted to live on just one species for their entire lives. That includes fungi and viruses, as well as the more grimace-inducing parasites like lice and intestinal worms.
Producer Christie Taylor talks to Duke Lemur Center researcher James Herrera, the first author on new research that found if endangered primates do disappear, nearly 200 species of primate parasites might also. They talk about why that loss could have consequences—not just for dwindling primates, but also for us.
The World According To Sound: How Spiders Shake Things Up For Love
Amorous arachnids sing to their lovers without making a sound. Instead, they like to shake things up.
Spiders aren’t powerful enough to vibrate the air, the way actual singing does. Instead, they use the ground. Male spiders send vibrations down their legs, and into whatever they’re standing on. Nearby females “hear” the song vibrating up their legs.
Humans can’t hear these spider songs with our ears, but we can listen to them with the help of a laser doppler vibrometer. This instrument can make non-contact vibration measurements of a surface. It shoots a laser beam at a particular surface, and depending on how much that surface moves, it can then measure the frequency and amplitude of the vibration, based on the Doppler shift of the reflected laser beam.
Hear an example of these lovelorn spiders on The World According to Sound, a live audio show, online listening series, and miniature podcast that focuses on sound, not story. Producers Chris Hoff and Sam Harnett create intentional, communal listening experiences as a way to “reclaim autonomy in a visually dominated world that is increasingly fracturing our attention.” The spiders in this piece were recorded by researchers in Damian Elias’s lab at UC Berkeley.
This recording is part of their next listening series, an immersive listening party where audiences from all over the globe will be invited to experience a world of sound together, beginning in January 2022. You can get a ticket to the series here.
