Many social insects, such as ants, change their behavior stereotypically from nursing to foraging as they age, a concept known as temporal polyethism. Biogenic amines are associated with these specifi...

Only germ cells can give rise to a totipotent embryo, yet a conserved transcriptional program for germ cell identity remains elusive. Profiling Drosophila primordial germ cells (PGCs) across embryogen...

During meiosis, chromosomes must find, pair, and synapse with their homologous partners in the crowded milieu of the nucleus (1). Although homology detection is generally attributed to recombination, ...

Many arthropods, including insects, harbor endosymbiotic bacteria. As bacteria transitioned to live inside host cells, free-living bacterial ancestors of endosymbionts reduced their genomes in a proce...

Modular synthetic G-protein-coupled receptors with nanobody-based ligand-recognition domains can be designed and used to programme transgene expression, real-time fluorescence or endogenous G-protein ...

Abstract. Ciliates undergo developmentally programmed genome elimination, in which small RNAs direct the removal of transposable elements (TEs) during the

Highlighted Article: An inducible Cas3*/Cas7* sensor demonstrates that non-apoptotic caspase events occur in zebrafish neural stem cells. In cooperation with the stress-induced transcription factor At...

Polyploidy, or whole-genome duplication (WGD), both a strong evolutionary and ecological force and a

Gametes in many species develop in cysts—clusters of germ cells formed by incomplete cytokinesis—that remain connected through intercellular bridges (…
