A competition for RNA drives the localized assembly of RNA granules in the C. elegans embryo.

RNA molecules cause the proteins involved in the formation of germ granules to coalesce into liquid droplets.

Regulatory hierarchies controlling sex determination and X-chromosome dosage compensation between closely-related nematode species are conserved, but X-chromosome target specificity for the condensin dosage compensation complex has diverged, thereby contributing to reproductive isolation.

Systematic analysis of C. elegans zygotes manipulated to divide equally demonstrates that daughter cell size asymmetry is critical for proper cell cycle timing, positioning, and fates during subsequent embryogenesis.

Neuronal circuits can be disrupted by ire-1-dependent mRNA decay to affect germline tumor cell identity by regulating cross-tissue communication in Caenorhabditis elegans.

The planarian mex3-1 gene is required for non-stem cell fates and suppresses a stem cell fate in differentiating cells.

An in-depth exploratory analysis of the evolutionary and epidemiological dynamics of SARS-CoV-2 in Mexico during the first year of the epidemic provides an overview of different virus dynamics between the developing and developed world (represented by the USA and Mexico).

A systemic hormone controls progenitor fate decisions independent of local fate determining pathways in the adult intestinal stem cell niche of Drosophila melanogaster..

A hormone released after mating acts directly on adult intestinal progenitors and differentiated epithelial cells in Drosophila to change their homeostatic setpoint and maximise fecundity.

Cryptic alleles affecting embryonic development are widespread in wild C. elegans populations.
