This study shows that vitamin B12 regulates RAS/MAPK-mediated cell fate decisions in C. elegans through one-carbon metabolism, with conserved effects in mammalian cells.

The paper shows that cell size predicts physiological germ cell death in C. elegans, regulated by actomyosin contractility at apical rachis bridges.

The paper examines the effect of proto-Y chromosomes on gene expression in house flies and finds minimal effects despite evidence of selection maintaining polygenic sex determination.

This study identifies the yellow ortholog as the brown body locus in houseflies using CRISPR-Cas9 and confirms its role in melanization.
