PIWI clade Argonautes are essential for transposon silencing. Without them, animals are sterile due to massive transposon activity.

But how does piRNA-guided target interaction translate into silencing?

PhD student Júlia Portell Montserrat has an intriguing answer

A lovely example of how extensive cryoEM data classification can provide new insights into the recognition of the nucleosome by nucleosome-modifying proteins.

Thank you, Harmit!
When people celebrate the individual genius of folks in science, they should also
mourn the collective loss of genius of folks who were actively discouraged or disadvantaged from a career in science because of the same person(s)

RIP James Watson. Reading The Double Helix in high school was one of the first times I felt the thrill of scientific discovery. But his later statements were also a stark reminder that great science and deeply flawed views can coexist in one person.
The obituary of someone who gained widespread fame through remarkable achievements at a young age and then expected to be taken seriously for anything he said thereafter.

just in time for the opening of the @hohmannulrich.bsky.social group at @imbmainz.bsky.social
what started as a project on how cells export piRNA precursors, ended up as a tour de force in mRNA export. truly wonderful collaboration with @plaschkalab.bsky.social at the @viennabiocenter.bsky.social
New paper alert! Scientists in Clemens Plaschka’s lab at the IMP and @juliusbrennecke.bsky.social's lab at
@imbavienna.bsky.social solved a decade-old puzzle, uncovering how the information molecule mRNA travels from the cell’s nucleus to its periphery. More: bit.ly/4nHcvys

How is epigenetic information inherited? We found that CDCA7 proteins are critical players in the inheritance of DNA methylation at CG sites in plants, and this is true both in the lab and in the wild. How does this work? 🧵👇
New paper! Work led by @p-bourguet.bsky.social and Frédéric Berger at the GMI of the @oeaw.bsky.social and @esasaki007.bsky.social identified how protein CDCA7 helps plants stably maintain epigenetic modifications across generations.
