Transposable elements are not reactivated in natural hybrids of the yeast Saccharomyces paradoxus, but their accumulation is genotype-specific and is not predicted by the evolutionary divergence between a hybrid's parents.
Theory explains how transport of gene expression vortices by cell advection may cause intermingled defective and normal segments along the body axis during resynchronization experiments in the zebrafish segmentation clock.
Previously uncharacterized long repeat sequences are associated with significant genome variation that can increase fitness and promote antifungal drug resistance in diverse isolates of Candida albicans.
A protein called RNF10 relays messages from synapses to neuron cell nuclei, and is responsible for long-lasting modifications of dendritic spines as observed after activation of synaptic glutamate receptors.
Swine populations worldwide are sporadically infected by influenza viruses from humans and birds leading to geographically heterogeneous swine influenza virus populations that pose epizootic and pandemic threats.
