If you heard about anvi'o but never had a chance to figure out what it really is, please consider watching this 12-minute video by Iva Veseli: www.youtube.com/watch?v=fExu... It is a short and sweet introduction to what (and what not) to expect from anvi'o 😇

What makes human guts and coral reefs similar? Here is a blog post with some thoughts on ecosystem stability, stress, and microbiome, following a fresh pre-print by Marko Terzin et al: merenlab.org/blog/coral-r...
merenlab.org
From coral reefs to human guts: stress is stress
Reefs and colons share no taxa, no host, no timescale, but they report stress the same way, which tells us where NOT to look for solutions.

A new blog post on a microbiome/cancer study that earns a second thought rather than just a nod or a shrug: merenlab.org/blog/sacchar... And LET THE RECORD SHOW that this post COMPLETELY addresses the incorrect claim that Meren only complains about microbiome studies.
