The association between the bacterium Fusobacterium nucleatum and human colon cancer is more complicated than it first appeared.

A multidimensional chemical mapping strategy enables confident determination of the structures of non-coding RNAs at 1-nm resolution, including previously intractable riboswitch and human regulon states.

Microbial populations are continuous along the gastrointestinal tract, with increased transmission in colorectal cancer and rheumatoid arthritis patients.

Oral bacteria colonize the gut more frequently than previously thought.

A multi-cohort analysis of 2,500 gut microbiomes and five major diseases discovers that disease-microbiome associations display specific age-centric trends, with diseases characterized by age-centric trends of species gain/loss.
