‘Breakthrough’ In Sudden Infant Death Syndrome Research Is Misleading Last week, headlines made the rounds in online publications and social media that there was a massive breakthrough in research about SIDS: Sudden Infant Death Syndrome. A study out of Australia concluded that babies who died of SIDS had significantly lower levels of an enzyme called BChE. This study was met with cheers by people desperate to understand why SIDS happens. But many experts say we need to pump the brakes on the celebration. While the study may be promising, it was based on a very limited sample—just 26 babies who had died of SIDS. A variety of factors could explain their different levels of BChE, says Dr. Rachel Moon, a professor of pediatrics and SIDS research at the University of Virginia. Moon explains that there are two major hurdles for researchers trying to investigate the causes of SIDS. First, as grieving parents are very unlikely to consent to their deceased child’s use in medical studies, the sample pool for genetic testing of SIDS death is incredibly small. Secondly, there are just very few people who specialize in the syndrome; Dr. Moon suspects there are one hundred or fewer researchers of SIDS in the entire world. She joins guest host John Dankosky to discuss how these factors make it hard for researchers to study why some babies continue to die prematurely. Period Tracking Apps And Digital Privacy In A Post-Roe World After the leak of the Supreme Court’s pending decision on Roe v. Wade law, digital privacy experts have been raising an alarm about digital privacy. Millions of people use apps to track their menstrual cycles—the popular app Flo has 43 million active users. And Clue, a similar company, says they have 12 million monthly active users. But in recent weeks, many on social media have been urging others to delete their period tracking apps, saying that the data you share on them could be potentially be used against you if abortion becomes criminalized in states across the country. Guest host John Dankosky talks with Laura Lazaro Cabrera, legal officer at Privacy International, about what kinds of data period tracking apps collect, how personal health data can be used in court, and how to protect your digital privacy. How Can We Inspire The Next Generation Of Female Scientists? The work of pioneering female scientists like Marie Curie and Jane Gooddall have served as an inspiration to many aspiring scientists. But less well-known are the early and mid-career female scientists who are working to answer some of today’s biggest scientific questions. A new book from National Geographic offers kids and tweens a look into the day-to-day lives of women working in the fields of volcanology, biology, anthropology, astronomy, and more. A central theme among the profiles is persistence in the face of obstacles. Producer Shoshannah Buxbaum talks with Clare Fiesler, conservation biologist, National Geographic explorer, and co-author of No Boundaries: 25 Women Explorers and Scientists Share Adventures, Inspiration, and Advice. Transcripts for each segment will be available the week after the show airs on sciencefriday.com. Subscribe to this podcast.
