I don't follow all the latest advances in EM closely, and I don't even fully grasp what this means for chromatin biologists, but this is absolutely amazing to see. This is why I love microscopy: things that once existed only in your imagination are suddenly right there in front of your eyes.

Crane pair dances follow hidden rules, with performances revealing partner-driven timing
Animal pairs engage in mutual signaling by simultaneously performing a diverse repertoire of behaviors. A famous example is the sophisticated dance (mutual displays) performed by bird pairs.

How salient is human eye appearance compared to that of other primates? This excellent new study by Perea-García et al. suggests that under some conditions, chimp-like eyes actually have a signalling advantage. 🧪

To our dismay, the artist and author Marjane Satrapi has passed away. As she wrote, ordinary Americans and Iranians have more in common with each other than we do with either of our governments, which have far too much in common with each other. We honor her memory and oppose the war.
