A burst of articles for your Monday digest. Quite a few highlights emerge from this Digest. There can be racial disparity in gastrointestinal cancer risk. The stress we experience now might influence our children’s aging in the future. And you might want to think twice about choosing between 16S and metagenomic sequencing, depending on the type of samples you have.
