"Use it or lose it." This is great advice for exercise, but when cells need to slow down or go dormant, they need to store ribosomes to recover growth in the future. They use hibernation factors to do this. Here is our latest story on how archaea hibernate ribosomes (1/7):

A miniature CRISPR-Cas10 enzyme confers immunity by an inverse signaling pathway Microbial and viral co-evolution has created immunity mechanisms involving oligonucleotide signaling that share mechanistic features with human anti-viral systems. In these pathways, including CBASS a...

Preprint alert! ✨ In this project that I co-led with @benadler.bsky.social, we show that a miniature CRISPR-Cas10-like enzyme, mCpol, uses a novel inverse signaling mechanism to prevent the spread of viruses that attempt immune evasion by depleting host cyclic nucleotides.
