Two novel LOTUS-domain proteins are core germ granule components that directly recruit Caenorhabditis elegans Vasa, regulate germ granule size and localization, and provide an organizational framework for ribonucleoprotein complexes.
The overactivation of noradrenergic inputs to the amygdala during severe fear learning increases memory stability at the expense of lability, rendering the trace resistant to memory destabilization and reconsolidation.
Functional analyses provide evidence for a complex Nod factor signalling where NFRe is necessary for maintaining an optimal symbiotic signalling in the susceptible root zone, and initiation of nodule primordia on the expanding root system.
Propagation, speed and shapes of genetic waves of expression during development can be modeled by a simple interplay between two transcriptional modules (dynamic/static), which explains robustness and precision of patterning.
Noisy circadian clocks in Anabaena, coupled by cell-cell communication, display high spatio-temporal coherence and can be robustly described by incorporating demographic noise in a theoretical model of coupled clock arrays.
