Mosquito-Borne Diseases Are Spreading | ‘Slingshot’ And A Space Mission Gone Wrong

Several states have reported cases of the rare but serious mosquito-borne illness eastern equine encephalitis. And, the new sci-fi movie "Slingshot," about an astronaut’s mental breakdown, prompts questions about how to prepare humans for long-term space travel.

This week, a New Hampshire man died of eastern equine encephalitis (EEE), a rare but extremely serious disease caused by a mosquito-borne virus. Human cases of EEE have also been reported in Wisconsin, New Jersey, Massachusetts, and Vermont, causing some municipalities to step up mosquito control efforts or attempt to limit outdoor activities during peak mosquito times at dawn and dusk.

Other mosquito-borne diseases are on the rise as well. Oropouche fever, a viral disease typically found in South America, has been spotted in the US—and in Brazil, health officials are reporting an 800% increase in the disease. Dengue fever, also spread by mosquitoes, has been increasing across Europe. Experts attribute all the surges to climate change, which has brought warmer, wetter weather that has allowed mosquito populations to thrive and expand their ranges.

Sophie Bushwick of New Scientist joins guest host Rachel Feltman to talk about climate, mosquitoes, and disease, and how communities are trying to curb the spread. They also tackle other stories from the week in science, including a puzzling result in a dark matter search, how fruit flies change their threat perception during courtship, and investigations into how marmoset monkeys call each other by name.

The new movie “Slingshot,” a sci-fi thriller about a yearslong mission to Saturn’s moon Titan, is out in theaters today. It follows the crew members, played by Casey Affleck, Laurence Fishburne, and Tomer Capone, as they start to unravel, highlighting how long, lonely missions can put astronauts’ well-being in peril.

While the movie is certainly a work of science fiction, it does remind us that a lot can go wrong in space, both physically and mentally. So as humans get closer to embarking on long missions to places like Mars and beyond, how are real space agencies thinking about keeping them happy and safe?

Science Friday’s digital producer of engagement Emma Gometz sat down with “Slingshot” director Mikael Håfström, and former NASA organizational psychologist Dr. Kelley Slack, to answer those questions and more.

Transcripts for each segment will be available after the show airs on sciencefriday.com.
