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.
