A fundamental feature of complex biological systems is the ability to form feedback interactions with their environment. A prominent model for studying such interactions is reservoir computing, where learning acts on low-dimensional bottlenecks. Desp

Individuality and slow dynamics in bacterial growth homeostasis

Autor: Susman, Lee, Kohram, Maryam, Vashistha, Harsh, Nechleba, Jeffrey T., Salman, Hanna, Brenner, Naama

Microbial growth and division are fundamental processes relevant to many areas of life science. Of particular interest are homeostasis mechanisms, which buffer growth and division from accumulating fluctuations over multiple cycles. These mechanisms

Single-cell protein dynamics reproduce universal fluctuations in cell populations

Autor: Brenner, Naama, Braun, Erez, Yoney, Anna, Susman, Lee, Rotella, James, Salman, Hanna

Protein variability in single cells has been studied extensively in populations, but little is known about temporal protein fluctuations in a single cell over extended times. We present here traces of protein copy number measured in individual bacter
