Mechanical interactions between bacterial species with different motility characteristics play an important role in spatial-temporal dynamics of multi-species bacterial colonies and can lead to formation of complex patterns.
A cross-campus, cross-career stage and cross-disciplinary series of discussions at a large public university has produced a series of recommendations for addressing the problems confronting the biomedical research community in the US.
The helical rod structure and dynamic spring-like properties of the type 1 pilus are evolutionarily fine-tuned for functioning in host-pathogen interactions during urinary tract infection and gut colonization.
Quantitative microscopy and theory show that the size of Xenopus laevis egg extract spindles is controlled by a spatially-regulated autocatalytic growth mechanism driven by microtubule-stimulated microtubule nucleation.
Transcription factors that specify the identity of individual neuron types via activating terminal differentiation gene batteries also restrict cellular plasticity via altering the chromatin landscape.
