When transposons jump, genomes diverge - even in cultured cells.
I am happy to share our new preprint: a chromosome-scale genome assembly for Drosophila OSC cells, one of the key model systems in the piRNA field, especially for nuclear piRNA biology. 🧬🧵 (1/12)

The new European Butterfly Red List is published today, with worrying findings. Over 1/4 (28%) of Europe’s 442 species are threatened with extinction or are close to being so. The situation is far worse for our 148 endemic species, 40% are now threatened or nearly so www.bc-europe.eu/webpage.php?...

We currently have a call for support that has gone out to European labs, to support FlyBase-UK. We are asking our colleagues from labs in the US and other countries to wait for a similar call to them that will go out in the near future, to support the US sites. We thank you for your patience.
URGENT: FlyBase has lost practically all its funding overnight; even user fees are tied up in denied grant funding. 🤬🤯
Any lab using @flybase.bsky.social please donate using the link in post below.
This incredible community, on whose backs our #Drosophila labs depend, can't be left out to dry.

My lab studies bacterial infections. We spend a lot of time looking at (or for) species-specific genetic and genomic databases for hosts and microbes. FlyBase is the best of all—there is literally no comparison. Its existence is under threat. Please donate.
