The 34th Marian Smoluchowski Symposium on Statistical Physics came to an end with plenty of great talks. On Wednesday Maciej presented his research on mechanics of domain formation with analytical insights on spatial and temporal aspects of domain stability. Maciej’s talk was followed by Richard discussing how robustness and precision is achieved in the developing spinal cord by exploring system level-feedback between source and target tissue. We are looking forward to the next edition of Smoluchowski conference!
