The RNA exosome maintains cellular RNA homeostasis by controlling transcript abundance in the brain Higginson et al. present a cell-type-resolved atlas of RNA exosome dysfunction in the Drosophila brain, showing that pathogenic Rrp40 mutations disrupt RNA surveillance and neuronal integrity. This re...

I wanted to say thanks for your paper as well and congrats to your student! Wonderfully thorough and mechanistic story. It brought me great joy to see evidence that Nrd1 could bind to a mRNA independent of Nab3 in vivo. The phenotypic consequences of mutating Nab3 binding sites on PIC2 are amazing!😊

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.

Model organisms, in particular non-mammalian model organisms, such as yeast, Caenorhabditis elegans, #Drosophila and zebrafish, have long stood at the centre of biological discovery www.nature.com/articles/s41...
