Fly neurons carry a molecular ‘timestamp’ that encodes their birth order

mercredi 22 juillet 2026

Nature, Published online: 22 July 2026; doi:10.1038/d41586-026-02240-xA single-cell gene-expression atlas of the fly nerve cord mapped onto its wiring diagram has uncovered a simple shared gene-expression code. The code enables neurons to carry a molecular memory of the order of their birth (...)

Geomagnetic storms caused by solar wind might be more extreme than previously thought

mercredi 22 juillet 2026

Nature, Published online: 22 July 2026; doi:10.1038/d41586-026-02245-6The severity of geomagnetic storms — magnetic disturbances in Earth’s outer atmosphere — is widely understood to reach an upper limit as the strength of the solar wind increases. But this upper limit is an illusion that results (...)

Background genetics and new mutations interact to direct cancer evolution

mercredi 22 juillet 2026

Nature, Published online: 22 July 2026; doi:10.1038/d41586-026-02155-7Rerunning tumour evolution in mice shows how cancer develops after DNA damage and reveals that background genetics and acquired mutations interact to shape genome stability and selection. This provides experimental evidence (...)
