We also talk about what needs to be learned about diet, environment, and genetics to better understand this condition.</p> <p> </p> <p>This week’s episode was produced with help from <a href="https://podigy.co/">Podigy</a>.</p> <p> </p> <p><a href="https://www.science.org/content/page/about-science-podcast">About the <em>Science</em> Podcast</a></p> <p> </p> <p>[Image: NASA; Music: Jeffrey Cook]</p> <p> </p> <p>[alt: Maat Mons volcano on Venus with podcast symbol overlay]</p> <p> </p> <p>Authors: Sarah Crespi; Paul Voosen</p> <p> </p> <p>Episode page: <a href="https://www.science.org/doi/10.1126/science.adh8158">https://www.science.org/doi/10.1126/science.adh8158</a> </p> <p> </p><p>See <a href="https://omnystudio.com/listener">omnystudio.com/listener</a> for privacy information.</p>
