Silly AU shenanigans with Captain Hook Vox finally capturing the elusive merfish Alastor. I’m sure he has a fish bowl waiting just for him on his ship.

In bits of personal glee from the weekend:
- Con leafing through the (yes, I know, very late) mup calendar and laughing himself silly at the merfish and December pages
- also asking of Ewen Bremner had seen the Buttons page and immediately taking a picture of it to send him

With this “Behind the paper” story, I’d like to give special thanks to two remarkable contributors whose generosity made a big difference:
@jialinliu.bsky.social for the scMultiomics data behind the multiomic atlas,
and Guoqiang Yu’s group for sharing ITEC cell tracking, which enabled MERFISH-FATE.

Need to design your next Xenium/CosMx/Merfish experiment? Spapros, now out @naturemethods, allows for probe set selection for target spatial tx. Led by @KuemmerleLouis, it optimizes both cell type ID & within-cell type variation. nature.com/articles/s41592-024-02496-z github.com/theislab/spapros
