Science Friday Folgen

When you think of fungal infections, you might think athlete’s foot or maybe ringworm—itchy, irritating reactions on the skin. But other fungal diseases can cause much more serious illness. One of them is Valley Fever, caused by the soil fungus Coccidioides. In 2018, over 15,000 people were diagnosed with coccidioidomycosis, commonly known as Valley Fever, in the United States, mainly in the American West, and in parts of Mexico, and Central and South America. But the numbers could be much higher: The disease is commonly misdiagnosed and the hot spots are difficult to pin down. Plus, the endemic region could grow with climate change.  Science Friday digital producer Lauren Young takes us into the Central Valley in California—a Valley Fever hot spot—to learn more about how the disease spreads and the people it harms. She tells the story in a new feature on Methods, from Science Friday, using video, sound, and pictures, gives you a flavor of the challenges faced by scientists working to solve big problems.  Ira brings on Valley Public Radio reporter Kerry Klein, who helped us report this story, to tell us more about the communities Valley Fever is impacting and new treatments. He also talks with UCSF microbiologist Anita Sil to dig deep into fungal pathogens and the latest research.  This year’s Citizen Science Month may be winding down at the end of April, but you can help researchers collect and analyze their data all year long.  This week, citizen science platform Zooniverse has not one, but four projects you can help with: data analysis tasks that will hopefully calm, soothe, distract, and divert you from life in a pandemic. Whether it’s identifying cute raccoons in camera trap photos, looking for seasonal wind on Mars, identifying how antibiotics kills tuberculosis in petri dishes, or even transcribing the cursive of old letters from anti-slavery activists—Zooniverse wants to help you find diversion in data. Ira talks about these projects—and how to get involved with Zooniverse—with co-lead Laura Trouille, vice president of citizen science at Chicago’s Adler Planetarium.

Can Coronavirus Reactivate In Patients After Recovery? These days, newsfeeds are overloaded with stories of the coronavirus, but Science Friday continues to explain the science behind COVID-19 headlines. Here, we learn about South Korea reports of 116 patients who recovered from the disease tested positive. Angela Rasmussen, associate research scientist and virologist at the Columbia Mailman School of Public Health, breaks down how reactivation works in viruses in diseases such as herpes. Plus, Rasmussen talks about human challenge trials—where participants are given a vaccine and inoculated with a virus—and the debate over the usage of these trials to develop a COVID-19 vaccine. Earth Day Goes Digital Next Wednesday is the 50th anniversary of Earth Day, marking five decades of environmental actions, like community cleanup, planting trees, or marching in the streets.  But this year, coronavirus has led to the cancellation of planned marches and large-scale events. Instead, many people will be participating in a digital Earth Day. Ira talks to Kathleen Rogers, president of the Earth Day Network about what people can do to participate, parallels between climate change and coronavirus, and environmental action in the age of the Trump administration.  Uncovering Antarctica's Rainforest Scientists found 90 million-year-old evidence that Antarctica wasn’t always a snow-covered continent. New ice core research provides evidence that the frozen land was once a temperature rainforest. Marine geologist Johann Klages, an author on the study, discusses what temperature the Earth would need to be to support such an environment in Antarctica, and how that can be used to create more accurate climate models.  Show Off Your Backyard Birds And Bugs Get involved in Citizen Science Month by snapping pictures of nature from your backyard with City Nature Challenge.  Subscribe to this podcast.

You Aren’t Alone In Grieving The Climate Crisis As the consequences of unchecked climate change come into sharper focus—wildfires in the Amazon and Australia, rising seas in low-lying Pacific Islands, mass coral bleaching around the world—what is to be done about the emotional devastation that people feel as a result? In 2007, Australian eco-philosopher Glenn Albrecht described this feeling as homesickness “for a home that no longer exists,” which he called “solastalgia.” Others have settled on terms like “climate grief,” or, since environmental devastation can come without a changing climate, simply “ecological grief.”  For this chapter of Degrees of Change, Ira talks about adapting emotionally to climate change. First, he speaks with psychologist Renee Lertzman and public health geographer Ashlee Cunsolo about their research on the phenomenon of grief tied to environmental loss, and what they’ve learned about how people can adapt their grief into actions that can make a difference. Then, climate researcher Kate Marvel and essayist Mary Annaïse Heglar share their experiences simultaneously working on climate change, and grieving it.  Inequality In The Air Air quality is a known public health threat, attributed to seven million deaths around the world every year. Minorities, especially African-Americans, often live in areas of high air pollution. Now, scientists say pollution is linked to high rates of COVID-19 deaths, which may help explain why people of color are dying from COVID-19 at disproportionate rates.  Vox reporter Umair Irfan speaks with Ira about the pandemic’s inequitable impacts for some communities, as well as other coronavirus and climate change news from the past week.  Subscribe to this podcast.
