Microbes conquer the next extreme environment: Your microwave

Figure S1. Study design, data analysis and experimental strategy for linking the human gut microbiota, genetics, and obesity. Related to STAR Methods. (A) Basic information of a Chinese obese cohort (n = 1,005). (B) Shotgun metagenomic sequencing and taxonomic profiling analysis on 1,005 collected fecal samples. (C) Whole genome sequencing conducted on 814 collected blood samples, and the calculation of polygenic risk score (PRS) for BMI based on BMI-associated common variants. (D) Identification of obesity-enriched microbial taxa, and assessment of the impacts of gut microbiota and host genetics on obesity. (E) Experimental design of functional examination of M. rupellensis and E. coli with heterologous expression of a myo-inositol-degrading enzyme in vitro and in vivo.

Poop Frequency Linked to Long-Term Health, New Study Reveals

Bacteria in the gut convert bile acids produced by the liver into a wide array of new compounds. These molecules are akin to the language of the gut microbiome, allowing them to influence distant organ systems. Photo Credit: Lakshmiraman Oza/Pixabay

Resilient People Show Unique Brain and Gut Microbiome Patterns

Allen and his colleagues found evidence supporting the idea that changes to the gut microbiome play a role in the system-wide inflammation that often occurs with aging.

Gut microbes from aged mice induce inflammation in young mice

(A) Study flow and randomization. (B) Sample trial of an unfair offer in the ultimatum game. (C) Distribution of rejection rates of all offers for each group and each session. (D) Change in rejection rates of unfair offers across sessions for each group (to improve visibility, points are jittered).

Probiotics Linked to Increased Sense of Fairness, Even at a Personal Cost

How Microbes in the Digestive System Influence Social Behavior

By playing Borderlands Science, a mini-game within the looter-shooter video game Borderlands 3, 4.5 million gamers have helped trace the evolutionary relationships of more than a million different kinds of bacteria that live in the human gut.
