I was asked what papers I was currently finding of interest so here's a brief rundown.
My latest obsession is akkermansia muciniphila, which is a gram negative, anaerobic bacterium found in the human gut and only known since 2004. It was the first non-culturable bacteria to be sequenced (2015). It is the subject of intense interest and study currently as a key bacteria species for optimal gut health, has been found to have anti-inflammatory effects, and may help combat obesity and type 2 diabetes. It tends to be present in significant numbers in supercentenarians despite differences in diet, and there is also evidence that patients with A. muciniphila present in the gut respond better to immunotherapy.
here's some interesting and relevant papers:
