Galileo’s Battle Against Science Denial Galileo Galilei is known as the father of observational astronomy. His theories about the movement of the Earth around the sun and his experiments testing principles of physics are the basis of modern astronomy. But he’s just as well known for his battles against science skeptics, having to defend his evidence against the political and religious critics and institutions of his time. In his new book Galileo and the Science Deniers, astrophysicist Mario Livio talks about the parallels of Galileo’s story to present-day climate change discussions, and other public scientific debates today. Monitoring Your Pandemic Health, From Your Home In recent weeks, the FDA has given the go-ahead to several tests for COVID-19 that can be performed remotely, from your own home. Such tests could help greatly expand testing capacity, an essential part of plans for recovery—but only if the tests are sensitive and reliable. Researchers are also working to develop other ways of using tech to monitor the outbreak, from heart rate monitors in smartwatches to sampling community sewage plants for evidence of the virus. Eric Topol, the founder and director of the Scripps Research Translational Institute, joins Ira to talk about some of the technology that could be brought to bear to get a better picture of the COVID-19 pandemic. The Origin Of The Feces For some researchers, nothing is more exciting than finding fossilized feces. These ancient poops are called coprolites, and they’re quite rare. Despite their less-than-glamorous-origins, each one is a gold mine of information about who left it behind. That’s because fecal fossils are a snapshot of the microbiome from which they came. Some researchers say studying these ancient records of diet and bacteria could help us learn about modern problems such as lactose intolerance and gut inflammation. Christina Warinner, assistant professor of anthropology at Harvard University in Cambridge, Massachusetts, joins Science Friday producer Kathleen Davis to talk coprolites, and what ancient feces can tell us about our ancestors, and ourselves.
