great thread on Jim Watson from @jeremymberg.bsky.social, an insightful perspective
Bluetorial-Jim Watson
I met Jim Watson a few times but did not know him well. However, I was greatly influenced by his book “The Double Helix”. He was a complicated human being with some very, very bad features, but some good contributions.
What follows is my personal perspective.

In @elife.bsky.social, our OpenSpliceAI paper, led by @kuanhaochao.bsky.social, is now 'official' though it's been online since July. If you want to enjoy the reviewers' comments and our responses, check it out at: doi.org/10.7554/eLif...
OpenSpliceAI provides an efficient modular implementation of SpliceAI enabling easy retraining across nonhuman species
OpenSpliceAI is an open, retrainable framework for splice site prediction that enables rapid, memory-efficient, cross-species analyses at scale with accuracy comparable to SpliceAI.

Introns have to come from somewhere, right? @celineh2ooo.bsky.social and I looked at multiple genome alignments with 1000s of genomes and found 342 cases where humans (and our relatives) had gained a new intron. Still not sure where these come from, but it's a fascinating question
@celineh2ooo.bsky.social and @stevensalzberg.bsky.social compared 3,493 vertebrate genomes to identify 342 gains of introns in human genes, tracing their origins and identifying cases of intronization as a mechanism of intron emergence.
