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...

Sex hormones and cancer-cell sex influence tumor growth, but other sex-dependent drivers of oncogenesis remain unclear. Here, the authors reveal that the sex of central neurons alters the peripheral t...

Dans une étude publiée dans Current Biology des scientifiques montrent que la compensation de dosage, un mécanisme qu

Tournière et al. uncover the biological roles of sex chromosome dosage compensation, showing it is broadly dispensable except in the respiratory system during metamorphosis, where X chromosome dose de...

Abstract. To limit transposable element (TE) mobilization, most eukaryotes have evolved small RNAs to silence TE activity via homology-dependent mechanisms

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.

Freire-Delgado and Brunet discover a new mode of cell motility in choanoflagellates, the closest relatives of animals. Under mild confinement, choanoflagellate move over surfaces without cell deformat...

FlyBase lost a multimillion dollar grant when the Trump administration cut off Harvard’s federal funding in May. Now the repository is laying off staff — and researchers worldwide are worried.

To rehabilitate the general view of women's contributions to the history of science, the CNRS is part of a commission that aims to inscribe

Birds have evolved a unique sex chromosome dosage compensation mechanism involving the male-biased microRNA (miR-2954), which is essential for male survival by regulating the expression of dosage-sens...

The Trump administration is still prohibiting National Institutes of Health (NIH) staff from issuing virtually all grant funding, an NIH official tells Popular Information.

Sameer Quazi An English university has issued a finding of research misconduct against a former graduate student and is requesting 10 retractions of his published work, which they say bears the mar…

The evolutionary water-to-land transition involved the separation of the skull from the pectoral girdle, though these musculoskeletal changes have not been deeply characterised. Here they show that th...

Transgenic markers and tools have revolutionised how we study cells and developing organisms. Some of the elements needed to construct those tools are universally applicable (e.g. fluorescent proteins...

Nature Communications - The pluripotency program is maintained by transcription factors from the Sox and POU families. Here they identify SOX and POU factors from unicellular relatives of animals...
