The test subject spent roughly a year in space. Here's the results from a battery of 10 cognitive tests. Striking result: postflight, many show major declines, sometimes 2 or more standard deviations:pic.twitter.com/e1uOCJewy3

This is an incredibly interesting, rich, and detailed controlled study (with a twin on the ground) of the effects of human spaceflight on the human body. Every paragraph is a goldmine.https://science.sciencemag.org/content/364/6436/eaau8650 …

Another remarkable result: telomeres lengthened(!) substantially during the flight. And returned to normal postflight.pic.twitter.com/5FP19MLwb2

They appear to have simply measured every darned thing they could, so this should be a marvellous data set for the future. Here's the short abstract of results, for (a rather understated) flavour, but the whole paper is really interesting and worth reading.pic.twitter.com/ZHyF9pqi7d

I'm afraid sample size of 1is too small to make any generalization about the rest of humans. Does this apply only to those people who are the same race, gender, age as those who were in the experiment?

A sample size of 1 is still an existence proof. We use them all the time in astrophysics while collecting more data.
