Can Memories Be Inherited? Dr. Oded Rechavi on RNA, Epigenetics & Evolution | Ep. 13

Can memories be inherited? In this episode of In Vivo, Dr. Oded Rechavi challenges long-held genetic dogma, revealing how RNA molecules, not just DNA, can store and transmit information across generations.Topics we cover:- How small RNAs bypass the Weismann barrier to transmit memory- Why our ancestors’ experiences might shape our biology- How C. elegans experiments reveal a hidden layer of inheritance- What this means for evolution, epigenetics & gene regulation- The controversial history of Lamarckian inheritance- Could RNA therapy redefine medicine, memory & disease treatment? About Dr. Oded Rechavi:Dr. Oded Rechavi is a leading researcher at Tel Aviv University, whose work on transgenerational inheritance has redefined how we think about heredity, memory, and the evolution of life itself.Listen in to explore the future of genetic inheritance and why RNA might be rewriting biology!Introduction to Inheritance Beyond DNA - 00:00:00The Weismann Barrier Explained - 00:03:56Weismann Barrier in Relation to Darwin's Evolution - 00:06:08Introduction to C. elegans and RNA Inheritance - 00:08:27RNA and Epigenetics: Challenging Traditional Inheritance - 00:09:10Mechanisms of RNA Transfer in C. elegans - 00:14:40Amplification and Persistence of RNA Across Generations - 00:15:56Example of RNA Memory in C. elegans Behavior - 00:19:47RNA's Role in Viral Immunity in C. elegans - 00:26:28RNAi and the Fight Against Genomic Parasites - 00:28:05Duration of RNA-Based Memory in Generations - 00:33:33Speculation on RNA Loss and Adaptation - 00:34:43Differences in RNA Transfer in Sperm vs. Egg - 00:38:34Time Frame for Environmental Stress to Affect Generations - 00:41:13Transgenerational Effects in More Complex Animals - 00:43:13Controversy Surrounding Transgenerational Epigenetics - 00:45:23The Dynamic and Fractal Nature of Cellular Information - 00:48:23Speculation on RNA Inheritance in Humans - 00:49:55Potential Applications of RNA Inheritance Research - 00:52:56Philosophical Implications of Inherited Memories - 00:54:36Scientific Communication Through Memes - 00:55:01Advice for Young Scientists - 00:57:27Closing Remarks - 01:00:00Dr. Rechavi's X page (the best science account on X) - https://x.com/OdedRechaviDr. Rechavi's lab - https://www.odedrechavilab.com/In Vivo on Spotify - https://open.spotify.com/show/5GBvPPvSx52O6ILuam4LoX?si=6c903566ae7b4761&nd=1&dlsi=254f9f5e78194002Introduction video attribution - The New York A
