'The Second Genome', a 3-part series presented by James Gallagher on BBC Radio 4.

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.

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.

 

What an absurd title. Typical.

 

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.
