Worm25 has been absolutely fantastic so far-congrats to everyone for your amazing work! One striking change in the talks this year is it seems like the consensus number of neurons in the adult hermaphrodite has returned to 302 after a few years at 300. Is CAN back?

After 5 years, our team has a new telomere-to-telomere gap-free reference genome for C. elegans. We published our first results in 2019; I thought we'd have our loose ends wrapped up by spring 2020. That prediction was ... slightly off.
But here's the genome now!

A reminder for new folks. BlueSky does not have an algorithm to raise posts of interest. It is incumbent upon you to do so via reposting. Liking things only provides feedback to the poster but does not promote the post. The signal to noise ratio is taking a brief beating, so great to help curate.
