Claude making a scientific discovery
Black-and-white three-part comic. In the first scene, one simple cartoon figure holds out a small round handmade-looking object and says, “I MADE THIS.” Another figure replies, “YOU MADE THIS?” In the second scene, the second figure is shown alone holding the object. In the final scene, that figure holds it proudly and says, “I MADE THIS”

I hate to do this with real data, but this is a persistent data vis issue in chromosome synteny riparian plots that we Need to get better at. Left, a synteny plot published today. Right, a rearranged version with exactly the same gross arrangement but with reordered chromosomes:
chromosome synteny riparian plot in which every chromosome has crossing lineschromosome synteny plot in which no chromosomes have crossing lines. The underlying structure is identical.

Most "tarantula-like" (Mygalomorph) spiders can't use silk to balloon around, unlike "typical" (Araneomorph) spiders. BUT. Ummidia trapdoor spiders can! (still only as babies, same as all spiders.) That's why theyre so widespread around the world compared to their relatives! #Arachtober 🧪🌿🕷️

At the same time, we made thousands of synonymous mutations in endogenous yeast genes and measured their growth. We used careful statistics and controls. Only 3%, 204 of 6874, had a fitness effect! This goes against a controversial recent result that most synonymous mutations had fitness effects.
Scatterplot showing fitness effect of ~7000 synonymous mutations in yeast: read count at start vs log2 fold change. Most data points are not significant but 204 points are significant outliers, either advantageous or deleterious.
