Essentials: Genes & the Inheritance of Memories Across Generations | Dr. Oded Rechavi
Andrew Huberman and Dr. Oded Rechavi explore the mechanisms of genetic and epigenetic inheritance, examining how information flows from DNA to RNA and proteins. Rechavi explains the evolutionary barriers preventing the inheritance of acquired traits, such as the Weismann barrier and epigenetic reprogramming, and details groundbreaking research in C. elegans showing that small RNAs can transmit antiviral resistance and alter behaviors across generations. They also discuss the potential future implications of small RNA biology for mammalian health, reproductive medicine, and diagnostics.
- C. elegans has a fixed cellular blueprint of exactly 959 cells, including 302 neurons that share the same wiring diagram across every single individual worm. Read →
- Standard pre-pregnancy carrier tests evaluate fixed DNA, but small RNA profiles reflect dynamic, real-time lifestyle changes and metabolic states. Read →
- Nematode worms (C. elegans) lack specialized immune cells like T-cells and B-cells, defending themselves entirely through small RNA molecules and RNA interference. Read →
