Kim group shows that power law tail in replication lag time underlies bacterial persistence Persisters are antibiotic-tolerant cells that can evade antibiotic killing by ceasing replication.  They complicate antibiotic treatment, leading to treatment failure. Professor Minsu Kim and graduate student (now Ph.D.) Emrah Simsek quantitatively analyzed the non-replication periods of the persisters, and show that … More Kim group shows how power law tail in replication lag time underlies bacterial persistence

Prof. Nemenman reveals limits on precision of dynamic chemical sensing by biological cells. Living systems sense chemicals in their environment when the latter bind to their surface receptors. Such binding is subject to the shot noise, which limits the sensing precision. How precise is such sensing? This storied question was asked for the first time … More Prof. Nemenman reveals limits on precision of dynamic chemical sensing by biological cells.
