Exploding the Cambrian and building a DNA database for forensics

Exploding the Cambrian and building a DNA database for forensics

First, we hear from science writer Joshua Sokol about his trip to the Cambrian—well not quite. He talks with host Megan Cantwell about his travels to a remote site in the mountains of British Columbia where some of Earth’s first animals—including a mysterious, alien-looking creature—are spilling out of Canadian rocks. Also on this week’s show, host Sarah Crespi talks with James Hazel a postdoctoral research fellow at the Center for Genetic Privacy and Identity in Community Settings at Vanderbilt University in Nashville about a proposal for creating a universal forensic DNA database. He and his co-authors argue that current, invasive practices such as law enforcement subpoenaing medical records, commercial genetic profiles, and other sets of extremely detailed genetic information during criminal investigations, would be curtailed if a forensics-use-only universal database were created.
