Colliding ribosomes are potent signals of cellular stress. But do cells use ‘programmed’ ribosome collisions to regulate gene expression? I’m excited to present a new story from my lab led by Frederick Rehfeld(@fred-rehfeld.bsky.social) which revealed that the answer is YES! Read on to find out how👇

We have an exciting PhD opportunity to study ribosome hibernation in archaea using cryo-electron microscopy, tomography, microfluidics, omics, and confocal imaging. @daumlab.bsky.social, @lsiexeter.bsky.social Apply via: www.exeter.ac.uk/study/fundin... Any questions, IM me.

We’re excited to report work led by postdoc Jennifer Porat in the lab, finding that DNA accumulates on the surface of living cells and that the secreted extracellular protein DNASE1L3 can modulate its levels on B and T cells. With a new twist for ATAC-seq as well www.biorxiv.org/content/10.1...

'Cancer Research UK told The Observer that several pieces of research had been affected by...immigration costs, which have risen by 126% since 2019 and are up to 17 times higher than the average of comparable countries including France, Australia, the US and South Korea.' Not only cancer research.

This preprint from Helen Sakharova is one of the coolest things to come out of my lab: “Protein language models reveal evolutionary constraints on synonymous codon choice.” Codon choice is a big puzzle in how information is encoded in genomes, and we have a new angle. www.biorxiv.org/content/10.1...

In a new study by our @pelleeas.bsky.social, we reveal how Mrx4 organizes translational regulation of cytochrome b synthesis at the mitoribosomal tunnel exit. Thanks @kawresearch.bsky.social for funding and @stirlingchurchman.bsky.social for the fun collaboration! academic.oup.com/nar/article/...

Here, we show that bacterial ribosomes—often viewed as conserved drug targets—actually vary across species due to extensive sequence variation in their drug-binding residues. In some cases, this divergence may lead to intrinsic drug resistance in certain bacterial clades: doi.org/10.1016/j.ce...

I'm reading the report behind these headlines about glyphosate and it may be the most scientifically illiterate thing I've come across (although it's a close thing with the recent MAHA report). 1/n

Identified in the 1970s, the precise molecular function of the alternative initiation factor eIF2A has remained unclear. Here, we map its interactome and uncover a surprising role in ribosome-associated quality control (RQC) upon ribosome stalling. 1/x www.biorxiv.org/content/10.1...
