See Andrew Huberman live in New York, Los Angeles & San Francisco: https://go.hubermanlab.com/protocols-event In this Huberman Lab Essentials episode, my guest is Dr. Oded Rechavi, a professor at Tel Aviv University who studies genetics, epigenetics and the inheritance of acquired traits. We discuss how DNA, RNA and epigenetic mechanisms determine what information can pass between generations, and why acquired traits are generally not thought to be inherited. We also explain research in C. elegans showing how small RNAs can transmit antiviral resistance and influence behavior across generations, what these findings might mean for mammals and humans, and potential future applications for reproductive health and diagnostics.
