From Fluctuations to Function: Unveiling the Role of Stochasticity in Life‐Like Systems

von Aleksa Lakic et al.

· 14.08.2025

In this short review, we put forward the idea that randomly fluctuating, or stochastic, molecular events can and do play a role in the emergence of complex biological phenomena at longer length scales. There is a growing body of evidence of this occ...
