Super excited that this story by @borissieber.bsky.social is now on BioRxiv! For decades, we thought there was no MAPK scaffold for the ERK-like cascade that promotes sexual reproduction in fission yeast ... until Boris found it ! See the thread 👇 and enjoy the paper! doi.org/10.1101/2025...

The lab is on a roll. 2nd preprint in as many weeks! High levels of Cdc42 GTPase underlie an all-or-none decision to fuse. Great team effort led by PhD students @sajjitasaha.bsky.social and @aiswaryasajeevan.bsky.social www.biorxiv.org/content/10.1... @biology-unige.bsky.social

New lab preprint! High resolution mapping of the actin fusion focus reveals myosin V-dependent transport of formin for actin aster compaction. A very cool work led by @valthomas.bsky.social and nice collaboration with Andrea Picco and @kaksonen.bsky.social! www.biorxiv.org/content/10.1...
