A long but great digest today, with lots of diversity – a few studies of poultry gut microbiome and the effects food/probiotics have, a solid showing for human gut microbiome studies – covering its implications on a range of disorders, some news about biotech companies, studies on plants and from environmental sources, a promising analysis of techniques used for sampling for human gut studies, and my normal dosage of non-microbiology science.  Happy Holidays!
