So excited that our latest work is out! We have been working to understand how damaged tissue exits regeneration and returns to normal gene expression, and found a major role for the pioneer transcription factor Zelda in flies. Kudos to @anishbose.bsky.social @keatonschuster.bsky.social et al!

What do we see when looking at cells under the microscope? 👉Some are bigger than others, some are elongated and align with the neighbors & others seem to move. Cool, right? But wouldn't it be cooler to quantify these observations? I'm @juliaeckert.bsky.social. Let's explore some analysis software!‬

Many cells during development are exposed to caspase activation and yet survive. Why some die and not others ? We found out that the memory of previous caspase activation bias significantly later death comitment and bias death distribution and single cell decision www.biorxiv.org/content/10.1...

#Phosphofructokinase (PFK) is considered an irreversible glycolytic #enzyme. This study shows that #Trypanosomes are the only known organism to use PFK in the gluconeogenic direction under normal conditions, likely due to its compartmentalization within glycosomes @plosbiology.org 🧪 plos.io/43r84Qc
