That article is so low on detail! There's basically just this statement:
> Study findings indicate under stress, the ISS isolated strains were mutated and became genetically and functionally distinct compared to their Earth counterparts. The strains were able to viably persist in the ISS over time with a significant abundance. E. bugandensis coexisted with multiple other microorganisms, and in some cases could have helped those organisms survive.
The bacteria changed (how, why, can we see?), they survived in space (plainly the original bacteria also survived long enough to evolve), and possibly adapted/coexisted with other (unnamed) microorganisms.
And then they were brought back to earth to be studied.... That too surely impacts the study of 'bacteria in space'.

- verisimi 2y agoI've skimmed this, it makes no sense to me. There are some graphics. There are things like this: > The ISS genomes exhibited an average of 4568 genes, a significantly higher count than the average of 4416 genes found in the Earth genomes. Yes, 4568 is a significantly higher count than 4416. But if I took samples of this bacteria from different countries, would I see a similarly significantly different count? I've no idea.. is this even significant without this sort of comparison? I watched the video too. This really is just a bunch of stock footage, with the same info as the linked NASA article. Do others find this info to be compelling of anything? It seems that this could be a PR piece of some sort, for 'space science'. I don't get the significance.
