Edited to change the thread title to that of the BBC Radio 4 3-part series introduced by this online article in BBC Health News: http://www.bbc.com/news/health-43674270 Link to the first episode is in the article but is here for easier ref. http://www.bbc.co.uk/programmes/b09yddx5#play I posted it here in the forum for Health News and Research unrelated to ME/CFS, but fyi for those who don't know, a UK programme of research investigating the gut microbiome in ME is currently ongoing at Norwich Research Park: https://quadram.ac.uk/targets/me-cfs/ hub of the Invest in ME Research Centre of Excellence for ME: http://www.investinme.org/research-centre.shtml)
Sounds like the makings of a good Sci-Fi novel, with some form of intelligent life developing in there. Or some other-world species where it has evolved that way.
To boldly go... Yep I've changed the thread title to the series title instead, and hopefully that gives a better clue to the subject matter.
