1/13 — New pre-print from the Sternberg Lab in collaboration with Leifu Chang's Lab! TnpB nucleases have repeatedly given rise to TldRs, nuclease-dead RNA-guided transcription factors. Here we define the biological role of one TldR clade in its native host. Story: www.biorxiv.org/content/10.6...

The mechanistic and evolutionary diversity of programmed DNA elimination
Nature Reviews Genetics, Published online: 08 September 2026; doi:10.1038/s41576-026-01004-7Programmed DNA elimination is a developmentally regulated process in which specific DNA sequences are reproducibly removed from particular cell lineages. Here, the authors review the mechanistic diversity and evolutionary dynamics of DNA elimination, spanning chromosome breakage, whole-chromosome elimination and whole-genome elimination.

Super excited to share my postdoctoral work at @imbavienna.bsky.social @viennabiocenter.bsky.social - We discovered that some retrotransposons, or "jumping genes" 🧬, are able to spread from cell to cell via a new viral infectivity route. A short thread: 🧵👇 (1/7)

Opponent independent costs game vs. arms race. Geoff Parker on the importance of picking good terms.
Black text on a white background with a highlighted section in light blue. 

The text reads:
What has been your biggest mistake? There have been several: failing to write things up soon enough, not picking good terms — for example, ‘opponent independent costs game’ sounds very tedious compared to ‘arms race’. I should have spent more time learning mathematical techniques, and probably less time on my other hobbies, jazz and exhibition poultry. But perhaps my biggest mistake was not to have embraced molecular biology more fully.

The phrase ‘opponent independent costs game’ sounds very tedious compared to ‘arms race’ is highlighted in light blue.
