ancient microbiome research, many findings make it sound like humanity has fallen from a primordial, pre-technological grace.

ancient signaling pathway in intestinal cells in both insects and mammals. It continues a line of
research from Rheinallt Jones and Andrew Neish on how beneficial bacteria stimulate wound healing by activating ROS (reactive oxygen species).
