Old sausages with teeth.

A new study of the bizarre naked mole rat shows they evolved a DNA repair mechanism that may explain their longevity.

These burrow-dwelling rats have a maximum life span of nearly 40 years, making them the world's longest-lived rodent.

Too much light at night is bad for everyone. But most of the light polluting our night skies has nothing to do with safety on our roads and urban streets. It's mostly caused by advertising and poorly-mounted floodlights.

A little belated posting, but we (Emily Navarrete, Leonid Mirny, me) have an updated preprint in collaboration the Ines Drinnenberg, Héloïse Muller, José Gil Jr, + others on the strange and striking compartmentalization of silkworm chromatin: www.biorxiv.org/content/10.1...

Unique territorial and compartmental organization of chromosomes in the holocentric silkworm

Hallmarks of multicellular eukaryotic genome organization are chromosome territories, compartments, and loop-extrusion-mediated structures, including TADs. However, these are mainly observed in model organisms, and most eukaryotes remain unexplored. Using Hi-C in the silkworm Bombyx mori we discover a novel chromatin folding structure, compartment S, which is “secluded” from the rest of the chromosome. This compartment exhibits loop extrusion features and a unique genetic and epigenetic landscape, and it localizes towards the periphery of chromosome territories. While euchromatin and heterochromatin display preferential compartmental contacts, S domains are remarkably devoid of contacts with other regions, including with other S domains. Polymer simulations show that this contact pattern can only be explained by high loop-extrusion activity within compartment S, combined with low extrusion elsewhere through the genome. This unique, targeted extrusion represents a novel phenomenon and underscores how evolutionarily conserved mechanisms—compartmentalization and loop extrusion—can be repurposed to create new 3D genome architectures. ### Competing Interest Statement The authors have declared no competing interest.
