Hermaphroditic Caenorhabditis elegans slow the onset of mating-induced death through self-sperm-regulated insulin-like gene expression, which regulates the activity of the IIS/FOXO pathway, mTOR signaling, and the TFEB/HLH-30 transcription factor.
Combination of in vitro and in vivo approaches reveal how learning suppresses the microRNA system to trigger de novo synthesis of plasticity proteins, a missing link in the current model of microRNA-mediated translation in persistent synaptic plasticity and memory.

New germline gene expression, knockout, and optogenetic tools reveal essential roles for Gα-GPR-1,2/Pins as a regulatable membrane anchor and LIN-5/NuMA as an activator of cortical dynein in mitotic spindle positioning.

Coordination between crossover designation and synaptonemal complex disassembly is executed via a conserved MAP kinase pathway and is critical for accurate chromosome segregation during meiosis.
The IGF2 mRNA binding protein-2/IMP2, overexpressed in many common cancers, drives cancer cell proliferation by increasing the abundance of IGF2 and the oncogene HMGA1, which controls a network of effectors that enhance IGF2 action.

Stoichiometric interactions between microtubules and cortical force-generators set spindle size, position and dynamics, and its scaling with cell size in nematode species.

A combined chemical genetics, proximity labeling, and ADP-ribose site mapping approach shows that PARP-7 mono-ADP-ribosylates immune-relevant proteins on cysteine amino acids.
Spontaneous elongation of epithelial colonies is related to the orientation of the mean nematic cell elongation field, as shown and tested with experiments and theory.

The initiation of human genome replication requires the six-subunit origin recognition complex (ORC) and CDC6, with ORC playing additional roles during mitosis and in organization of the cell nucleus.
