Just a short post today. PLOS ONE has a paper about burn victims and gut microbiome, in which both humans as well as mice were studied, but I really disliked the mouse experiments, where mice were deliberately burned (by shaving them and dipping them in near-boiling water). As a scientist, I realize that animal experiments can be useful, but I very much dislike animal studies that involve deliberate burns, enormous tumors, and parabiosis. I hope that these types of experiments can soon be replaced by more animal-friendly versions.

In other news: a bacterium on satellite survived entry into the Earth’s atmosphere. How cool is that?
