Reverse development in a comb jelly

Science Sessions are brief conversations with cutting-edge researchers, National Academy members, and policymakers as they discuss topics relevant to today's scientific community. Learn the behind-the-scenes story of work published in the Proceedings of the National Academy of Sciences (PNAS), plus a broad range of scientific news about discoveries that affect the world around us.

In this episode, Joan Soto and Patel Burkhardt introduce us to a comb jelly with the ability to reverse its development to an earlier stage of life.

In this episode, we cover: •[00:00] Introduction •[00:54] Marine biologist Joan-Josep Soto recounts the history of research into reverse development. •[02:27] Soto and evolutionary biologist Burkhardt introduce the comb jelly Mnemiopsis leidyi and its life stages. •[04:04] Burkhardt explains why the researchers became interested in Mnemiopsis. •[04:48] Soto describes how the researchers induced reverse development in Mnemiopsis. •[06:13] Burkhardt explores hypotheses regarding why reverse development occurs. •[07:13] Soto talks about the lessons yet to be learned from Mnemiopsis. •[09:35] Burkhardt summarizes the caveats and limitations of the study. •[10:12] Conclusion.
