Highlights!!

Personalized microbiome-driven effects of non-nutritive sweeteners on human glucose tolerance – Jotham Suez – Cell a randomized-controlled trial (120 healthy adults) observed the effects of saccharin, sucralose, aspartame, and stevia on the human microbiome showed person-specific, microbiome-dependent glycemic alterations. Saccharin and sucralose significantly impaired glycemic responses.

A comprehensive evaluation of microbial differential abundance analysis methods: current status and potential solutions – Lu Yang – Microbiome → assessment of several differential abundance analysis (DAA) tools, using real data-based simulations, suggests that “none of the evaluated methods is simultaneously robust, powerful, and flexible, which makes the selection of the best DAA tool difficult”. These findings suggest that the application of a DAA method depends of data context.
