Stochastic cell migration modulates exposure to signals that regulate commitment in the nephron progenitor niche.

An analysis of influenza viruses from naturally infected people suggests a tight transmission bottleneck and little positive selection within hosts.

A study that models the evolution of drug resistance in tumors reveals that drugs are more effective when given in combination than sequentially, and that cure is much more likely when the drugs target different pathways.

Translation termination is a stochastic process that utilizes loosely coupled motions of its players to complete protein synthesis and release the newly synthesized nascent chain toward its cellular destination.

The complex process of protein translocation across membranes has been dissected into multiple key steps and the distributions of translocation rates indicate stochastic nature of the reaction.

The emergence of subpopulations that perform distinct metabolic roles has been observed in populations of genetically identical bacteria.

Advances in techniques for analysing single cells and tissues have inspired an international effort to create comprehensive reference maps of all human cells - the fundamental units of life - as a basis for both understanding human health and diagnosing, monitoring and treating disease.
