An active volcano on Venus, and a concerning rise in early onset colon cancer

On this week’s show: Spotting volcanic activity on Venus in 30-year-old data, and giving context to increases in early onset colon cancer First up this week, a researcher notices an active volcano on Venus in data from the Magellan mission—which ended in 1994. News Staff Writer Paul Voosen joins host Sarah Crespi to discuss how to find a “fresh” lava flow in 30-year-old readings. Next up, a concerning increase in early onset colon cancer. Kimmie Ng, director of the Young-Onset Colorectal Cancer Center at the Dana-Farber Cancer Institute and associate professor of medicine at Harvard Medical School, is here to talk about how these early colon cancers—those diagnosed before age 50—are different from those diagnosed later in life. We also talk about what needs to be learned about diet, environment, and genetics to better understand this condition. This week’s episode was produced with help from Podigy.
