The Islamic Republic has used internet shutdowns to execute Iranian protesters who took to the streets. I am taking political sponsorship of two brothers, Behrouz & Kourosh Zamaninezhad, who were among those affected.

15 years in the making, we confirmed that mitochondria - the powerhouse of the cell - have an unusual localization in patients who experience psychosis (including schizophrenia and bipolar disorders). You’ll never guess what kind of patient cells we used to make this discovery… 🧵
mitochondria from bipolar patients are closer to the nucleus in these images; control patients' are spread out further

Reaffirming the value of model organisms in training scientific minds - Nature Cell Biology
As biomedical research prioritizes human models and translational promise, classic model organisms are increasingly dismissed. Here we argue that they have a lasting value, both in enabling discovery and in cultivating scientific thinking, by training researchers in systems reasoning, integrative thinking and independent inquiry.
