Tracking fluorescent fusion proteins in competent pneumococcal cells reveals a polar hub for competence regulation, with the alternative sigma factor σX relocalizing DprA to this hub to mediate competence shut-off.
Genetic and transcriptomic analyses revealed that eIF4E S209 phosphorylation enables Myc and mutant KRAS cooperation in colon cancer through stress- and glutamine-dependent growth and addiction.
A disease-associated polymorphism in a related protein that regulates neurotransmitter release reveals that antiviral protein IFITM3 forms oligomers to rigidify membranes and inhibit virus fusion with cells.

Imprinted gene expression is set up during a critical window of early embryonic development, by the translation of parental imprints by oocyte-supplied Smchd1 into allele-specific gene silencing.
A bacterial tRNA gene set rapidly evolves, compensating the loss of one tRNA type by large duplication events that increase the gene copy number of a second, different tRNA type.
Inhibiting IRE1α decreases tumor cell proliferation and migration in hepatocellular carcinoma, therefore components of this ER-stress pathway may be therapeutically relevant for liver cancer.
