Gyrification of the cerebral cortex is essential for healthy brain development, and disruptions to this process lead to severe structural and functional abnormalities associated with long-term behavioural and psychiatric consequences. Basal radial glial cells (bRGC), residing in the expanded outer subventricular zone (oSVZ), are thought to drive gyrification. However, the transcriptional programs guiding this process remain po...

Gut microorganisms are crucial for many biological functions playing a pivotal role in the host’s well-being. We studied gut bacterial community structure of marine iguana populations across the Galápagos archipelago. Marine iguanas depend heavily on their specialized gut microbiome for the digestion of dietary algae, a resource whose growth was strongly reduced by severe “El Niño”-related climatic fluctuations in 2015/2016. A...
