Two mannequins walk into a science lab, and one’s got a big tick problem. She can teach humans how to check for ticks. Also, researchers used citizen science observations and machine learning to understand where fireflies are and what they need to thrive.In Wisconsin, Mannequins Help Teach People How To Spot TicksNationwide, Wisconsin is a hot spot for Lyme disease. And cases are rising, as climate change and development alter how humans interact with the ticks that transmit this disease. In Wisconsin, cases reported annually have more than doubled in the last two decades.With tick season underway, tick checks are one of the most important ways you can prevent infection. I recently visited the Midwest Center of Excellence for Vector-borne Disease, which is housed at the University of Wisconsin-Madison, where researchers are using a new tool to teach people how to do tick checks — mannequins.Read the rest at sciencefriday.comProtecting A Flickering Symbol Of Summer NightsWhen people talk about watching fireflies, a common comment is “You know, I don’t see as many fireflies as I used to.” Researchers are trying to figure out whether that impression is actually accurate, and which of the over 2,000 firefly species might be affected—and to do so, they need a lot more data. A recent paper published in the journal Science of the Total Environment used over 24,000 citizen science observations as well as machine learning models to try to better identify where certain species of fireflies can be found, and what types of habitat and climate they need to thrive.Dr. Sarah Lower, a firefly researcher at Bucknell University and a co-author of the study, joins guest host Annie Minoff to talk about some ways to protect fireflies near you, including preserving darkness and providing moist, permeable, natural soils for firefly larvae.Transcripts for each segment will be available after the show airs on sciencefriday.com.
