For too long, we have only had 2 sex-specifically spliced genes in the mosquito. Welcome to the world, MOSN! Males: big protein. Females: small protein. Fascinating new domain of unknown function.

Evolution of MOSN, a novel sex-specifically spliced neuronal gene in the Aedes aegypti mosquito

Sex-specific RNA splicing is a conserved mechanism for generating sexual dimorphism in insects, with the best-studied examples being fruitless and doublesex. To ask whether additional sex-specifically...

Rest in peace Jane Goodall, a true giant among scientists. Your breakthroughs into the secret lives of chimpanzees viewed through an anthropomorphic lens – without yet knowing that science had forbidden it – changed science forever, and with it how we see ourselves.

Excited to share our last paper describing how intestinal stem cell migration promotes gut regeneration! www.nature.com/articles/s41...

Pvf1-Pvr-mediated crosstalk between trachea and gut guides intestinal stem cell migration to promote gut regeneration - Nature Communications

Adult stem cells often reside in specialized niches that they exit upon injury. Here they show that in Drosophila, after damage the gut-associated trachea produces the PDGF-VEGF-related ligand Pvf1, which acts as a guidance cue directing ISC migration toward injury sites.
