There’s an idea bubbling up in medicine called the “digital twin.” The concept is to take personal health data like genetics, blood test results, tissue samples, MRI scans, and family history, and create a digital model of a patient that can be used to predict how a treatment might work for them. Think personalized medicine supercharged by AI.  For example, cancer researchers are working on models that would create radiation and chemotherapy treatment plans based on the specifics of a patient’s tumor. But these models aren’t ready for the clinic yet, and with so much patient data involved, privacy concerns abound.  Host Flora Lichtman talks with Caroline Chung, a radiation oncologist at the forefront of digital twin research. Guest: Dr. Caroline Chung is a radiation oncologist and the co-director of the Institute for Data Science Oncology at UT MD Anderson Cancer Center.

Farmers’ Almanacs have been around for hundreds of years, offering detailed advice about things like the best time to plant certain crops, and when to wean your calves. But do farmers actually use them? Host Flora Lichtman discusses their place in modern life with astronomer and Farmers’ Almanac contributor Dean Regas, and Missouri farmer Liz Graznak.  Plus, zebra finches build their nests with a keen eye for color. But is their style easily swayed by feathered peer pressure? Zebra finch expert Lauren Guillette fills us in. Guests: Dean Regas is an astronomer and former Farmers’ Almanac contributor based in Cincinnati. Liz Graznak is an organic farmer and owner of Happy Hollow Farm based in Columbia, Missouri.  Lauren Guillette is an Associate Professor of Cognitive Ecology at the University of Alberta.

In February, conservationists released 158 young tortoises onto Floreana Island in the Galapagos. The Floreana tortoise subspecies had long been thought extinct, but the discovery of close relatives on another island made a captive breeding effort possible.  SciFri turtle correspondent Charles Bergquist talks with conservationist Penny Becker about the science behind the reintroduction, and what it was like to return the species to an island that had not seen them since the 1850s. Plus, the latest on sea turtle nesting season, and an ancient sea turtle stampede. Guest: Dr. Penny Becker is CEO of the nonprofit Island Conservation.
