Wise words from Miltos "Be intellectually humble — if you are studying an interesting question, remember that the question is bigger than one’s intellect. Put your ego aside so you can learn from others, read a lot and respect your co-workers and colleagues at all levels."🙏

Really happy to see this one out: www.sciencedirect.com/science/arti... Alibek's drive & great coll w/ friends @gekaragoz.bsky.social & E. Hallacli resulted in a cool story that starts with our beloved #Marchantia and ends with iPSC-derived neurons 🤩🤪 A short 🧵

CEPLAS starts a number of new projects, and we are looking for 12 Postdocs ❗
CEPLAS projects are always highly collaborative, that means postdocs working with us will always closely interact with several CEPLAS research groups. Find all postdoc openings here: www.ceplas.eu/en/training-...

Cross section of hypocotyl of 8-week-old Arabidopsis thaliana. The ovac mutant displays enhanced secondary vessel differentiation (red) at the expense of parchenchyma cells. Images A2 and B2 show the vessel cells only. SR2200 and Fuchsin staining. Imaged by Donghwi Ko.

Recruitment of bifunctional regulator thermospermine to methylated ribosomes directs xylem fate Polyamines are often associated with ribosomes and are thought to stabilize their integrity. In Arabidopsis, the polyamine thermospermine (tSpm) affects xylem cell fate. tSpm induces translation of SU...

In @science.org this week, thermospermine affects ribosome methylation, which in turn regulates translation of xylem development proteins www.science.org/doi/10.1126/...

Gladys Mae West obituary: mathematician who pioneered GPS technology She made key contributions to US cold-war science despite facing huge barriers as a Black woman.

No joke: I got angry hate mail today for writing an obituary of a Black woman scientist—because the person felt she did didn’t deserve the recognition.

Which just makes me want to share it again: www.nature.com/articles/d41...

Model bacteria that lack (or have minimal) defense systems have been crucial for understanding bacterial immunity. Now, there is a model defenseless plant. One may expect that this model can accelerate discoveries on plant immunity
