How python hearts grow and shrink

How python hearts grow and shrink

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, Leslie Leinwand, of the University of Colorado in Boulder, and Claudia Crocini, of Charité – Berlin University of Medicine in Germany, describe how the hearts of constricting pythons change size after meals.

In this episode, we cover:
•[00:00] Introduction
•[01:19] What is the natural context for cardiac hypertrophy in constricting pythons?
•[02:48] What were the mechanisms involved in this process that you identified?
•[05:27] What did you discover about the mechanisms of heart size regression in these snakes?
•[07:24] What are the next steps in this line of research?
•[08:21] Conclusion.
