13 Aug 2018 --- A novel approach to identify the genes that may be important to help microbes live successfully in the human gut has been identified by a study published in PLOS Computational Biology. The approach utilizes a technique called phylogenetic linear modeling, which has often been used in ecology, but rarely in genomics. The researchers hope that the findings could be important for the development of new therapies to maintain or improve gut health, such as the design of better probiotics.
