In July 2024, Daylon and Arun attended the International Society for Stem Cell Research’s (ISSCR) annual meeting in Hamburg, Germany, and recorded daily episodes discussing highlights of the previous 24 hours. Here is the first of four episodes, where Daylon and Arun discuss the clinical focus of this year's meeting and the President's Symposium, including Dr. Magdalena Götz's talk on organellar heterogeneity and "moonlighting" proteins. They also talk about sessions on stem cells in low earth orbit and computational biology, including Dr. Jonathan Weissman's work on PerturbSeq and Dr. Matthias Lutolf's work on organoids on chips. Finally, they discuss a session on cultured meat.
