Beautiful work (as usual)! Always excited to see the work the lab produces!

Will be doing this for journal club in the upcoming weeks.
Glad to see our phoronid genome study featured on the cover of @currentbiology.bsky.social! It shows how genome structure can be used to test competing hypotheses of nested topology and how derived structural changes provide evidence for monophyly.

Our latest: combining single-cell RNA-seq from 16 species and HCR validation, we show that monoaminergic neurons share a conserved transcriptional identity across Bilateria. In contrast, we find no evidence for this program in non-bilaterian metazoans. www.biorxiv.org/content/10.1...

Lab’s 1st preprint!

Menstruation is understudied due to societal taboos + a biological challenge: mice (a key system for research + drug discovery) don’t menstruate.

@cagricevrim.bsky.social made menstruating mice + used them to discover early events in menstruation.

Please share! I'm looking for a postdoc. The position is to lead one of the following projects: 1) regulation of plant specialized metabolism by cell fate, or 2) foliar embryogenesis in the succulent plant Kalanchoe.

Learn more abt projects: cxli233.github.io/cxLi_lab/res...
Plant cells are totipotent, meaning individual cells have the potential to develop into a full organism, a property unique to the zygote for animals. However, in most species for most cells, plant cells are not spontaneously totipotent, since they must be treated with specific hormone combinations to unlock their totipotency. Species within the Kalanchoe genus is unique as they spontaneously develop foliar embryos that are fully realized plantlets with shoot and root from notches along the edges of leaves. We speculate that the progenitor cells that give rise to these foliar embryos are totipotent, and we are using single cell techniques to identify & characterize them. In addition to being a fundamental process for plant biology, we foresee unlocking totipotency has many biotechnological applications, such as faciliating genetic transformation and the development of synthetic organs of biomanufacturing.
