Our story on Srs2/PARI family DNA helicases linking chromatin bridges to the Aurora-B dependent NoCut checkpoint is now out in its peer-reviewed version. Thanks to @reviewcommons.org and @jcb.org for a smooth review process! Original preprint thread here: bsky.app/profile/long...
Dam, Moreno, Brownlow, @longchrom.bsky.social et al. @igbmc.bsky.social identify Srs2 as a key mediator of abscission inhibition in yeast and show that its human paralog PARI regulates abscission-associated events. rupress.org/jcb/article/...

We have wondered what a complex archaeal cell might look like ever since 2014. It’s been a long road (and the journey is far from over), but it’s a good time to pause for breath and look. These Asgard archaeal cells are a surprise! And that is the joy of being a cell biologist.
