Stem cell self-renewal strategies fall into two classes, and only strategies of different classes can be experimentally distinguished via static clonal data.

A new agent-based model enables predicting how coral species richness and functional diversity affect the functioning and resilience of coral reef ecosystems.

A coarse-grained model of microbial growth coupling fluxes of carbon and energy shows that resource allocation is a major explanatory factor of the observed variability of growth rates and growth yields across different bacterial strains.

Theoretical study shows how enzymes can achieve substrate proofreading by taking advantage of existing molecular gradients in the cell while not being endowed with structural features typically required for proofreading.

Despite the virus' error prone polymerase, influenza virus antigenic evolution is rare, even in previously immune hosts, virus replication occurs before producing new antibodies.

New experiments and theory reveal how the ability to see image details depends upon photoreceptor function and eye movements, and how fruit flies (Drosophila) see spatial details beyond the optical limit of their compound eyes.

Maternal positional information in the fly embryo can be read rapidly in spite of the gene-expression bottleneck and general examples of regulatory architectures that combine speed and accuracy are provided.
