Clone-FISH paper out: Manuscript/resource alert #microsky 🦠 We present a collection of 30 E. coli (CloneFISH) cultures, each carrying a plasmid for the heterologous expression of a (near) full-length 16S rRNA gene from one of 30 lineages of archaea, including 17 yet uncultured ones.

Wow! This is great, and now I'm keeping a lookout for a lot more archaeal FISH papers incoming!

The FPbase spectra viewer just had it's biggest software refactor in 6 years. It *should* be largely invisible to the end user (hopefully just faster and less buggy). Please let me know if you find any issues as you use it!
