  • Summary

  • Meet The Blind Birder Reimagining Accessibility In The Outdoors For many blind and low vision people, accessing outdoor spaces like parks can be challenging. Trails are often unsafe or difficult to navigate, signs don’t usually have Braille, guides generally aren’t trained to help disabled visitors, and so on. But nature recordist Juan Pablo Culasso, based in Bogata, Colombia, is changing that. He’s designed a system of fully accessible trails in the cloud forests of southwest Colombia that are specifically tailored to help visually disabled people connect with nature. The trails are the first of their kind in the Americas, and Culasso drew on his own experiences as a blind person and a professional birder to design the system. He talks with Maddie Sofia about how he designed the trail system and takes listeners on an adventure through the cloud forest he works in. Listen To Ethereal Sounds Derived From Space You’ve probably heard that if you scream in space, no one will hear a thing. Space is a vacuum, so sound waves don’t have anything to bounce off of. But that doesn’t necessarily mean that space is silent. A team of researchers are taking data from a variety of telescopes and assigning them sounds, creating song-length sonifications of beloved space structures like black holes, nebulas, galaxies, and beyond. The album, called “Universal Harmonies” aims to bring galaxies to life and allow more people, such as those who are blind and low-vision, to engage with outer space. Guest host Flora Lichtman talks with two of the scientists behind “Universal Harmonies,” Dr. Kimberly Arcand, visualization scientist at NASA’s Chandra X-ray Observatory, and Dr. Matt Russo, astrophysicist and musician at the University of Toronto. Listen to a selection of the ethereal sonifications of “Universal Harmonies.” Why You Should Thank Your Local Wasp It’s late in the summer, meaning any outdoor gathering with food and drink has a good chance of being visited by a pesky, buzzing wasp. But don’t reach for that rolled-up newspaper or can of bug spray. The wasps in your world play an important role that’s often overlooked. Far beyond the social hornets and yellowjackets people think about when they picture a wasp, the wasp world includes thousands of species. Some are parasitic, injecting their eggs into unwilling prey. Others hunt, either paralyzing prey for their young to feed on, or by bringing bits of meat back to a nest for their young. Some are strictly vegetarian, and live on pollen. Some are needed for the pollination of figs and certain species of orchids. Dr. Seirian Sumner, a behavioral biologist at University College London, says that if people understood the services provided by wasps the same way that they understand the need for bees, they might be more willing to overlook an occasional wasp annoyance—and might even be thankful for the wasps in their lives. In her book, "Endless Forms: The Secret World of Wasps," Sumner makes the case for wasps as nature’s pest control agents, as important pollinators that should be celebrated. And the pesky yellowjacket at your picnic? It’s probably being driven by a late-summer shift in functions within the nest, in which many of the workers die off and are replaced by sexual brood. Earlier in the year, worker wasps can bring bits of meat to the developing young, which reward them with sugary secretions. But later in the season, that food source dries up—so visiting wasps are probably searching for a bit of sugar just to get by. “Watch the wasp, see what she wants at your picnic,” Sumner advises. “Is she going for sugar, or is she going for some meat? Whatever you can work out that she wants, give her a little bit of it. Make a little wasp offering.” Sumner joins SciFri producer Charles Bergquist to talk about wasps, and make a case for why you should be thankful for the wasps in your neighborhood.
