Very interesting indeed, and so many questions to follow up on. As the relative abundances of RNA species don't seem to change, do overall protein concentrations decrease? Rates of cellular processes? Is the number game why expression variability of individual genes seems to increase with age?
Very interesting. Unless I’m missing something, this also seems to imply protein production is mRNA limited.

Here it is! Bonsai. Now there is really no more excuse for using t-SNE/UMAP. Bonsai not only makes cool pictures of your data. It actually rigorously preserves its structure. No tunable parameters. Incredible work by @dhdegroot.bsky.social. I'm so excited about this! www.biorxiv.org/content/10.1...
How do you visualize highly complex data without losing important information? Prof. Erik van Nimwegen’s team developed a new tool, Bonsai, that provides a faithful picture of the structure in the data. @erikvannimwegen.bsky.social @unibas.ch @dhdegroot.bsky.social @imbavienna.bsky.social

🚀 New preprint 🥳 Fantastic work by our recent PhD graduate Daan ! How are mRNPs remodeled as they exit the nucleus? We identify PAIP1 as a factor that promotes exchange of the nuclear poly(A)-binding protein PABPN1 for cytoplasmic PABPC1, coupling mRNA export to cytoplasmic mRNP maturation.
PAIP1 couples mRNA export to cytoplasmic mRNP remodeling and poly(A) homeostasis https://www.biorxiv.org/content/10.64898/2026.07.31.742013v1

Context: Gene expression noise has been observed to decrease with growth rate in E. coli. journals.plos.org/plosbiology/... Consequently, fast growing cells are more phenotypically stable, and this has major implications for phenotypic adaptation www.pnas.org/doi/10.1073/... 2/n
Genome-wide gene expression noise in Escherichia coli is condition-dependent and determined by propagation of noise through the regulatory network
Genome-wide flow cytometry measurements reveal that gene expression noise in bacteria is highly condition-dependent; while absolute noise levels of all genes decrease with growth-rate, theoretical mod...

What are the main sources of gene expression noise in bacteria, and why do slower growing bacteria exhibit more expression noise? TLDR: we found growth-rate fluctuations are a key driver of gene expression noise that increase as average growth rate decreases. www.biorxiv.org/content/10.6... 1/n

The key point here is rather "who would your rather trust"? Because what is offered is not for anyone to decide for themselves, but rather one is coerced to go along with decisions made by few. People are expected to follow the orders of someone who understands nothing.
1. "'Trusting the experts is not a feature of either a science or democracy," Kennedy said." It's literally a vital feature of both science and of representative democracy. I've written a fair bit about trust in expertise as a vital mechanism in the collective epistemology of science.

RNase L cleaves most tRNAs in the anticodon loops into various tRNA-derived RNAs (tDRs) including 5'-tDRAla that shows a translation inhibitory effect. Some tRNAs are also cleaved in variable loops bit.ly/3YTwlNq
