Naama does amazing work and she is a terrific person to work with. Highly recommended!

Here we show that buildup of uremic toxins during CKD generates nitrate in the colon. Nitrate supports expansion of Enterobacteriaceae, turning them into a major source of uremic toxins. Inhibiting nitrate production (iNOS inhibition) mitigates disease progression. www.science.org/eprint/YGNMK...

Microbiota-mediated induction of beige adipocytes in response to dietary cues - Nature In mice, a low-protein diet leads to a gut-microbiota-driven remodelling of adipose tissue towards brown fat, showing that gut microorganisms have a role in detecting and responding to a lack of protein.

Clostridia from preterm infants metabolize human milk oligosaccharides to suppress pathobionts and modulate intestinal function in organoids - Nature Microbiology Clostridium perfringens lacking perfringolysin O toxin isolated from preterm infants metabolizes human milk oligosaccharide disialyllacto-N-tetraose to produce metabolites that promote the growth of commensal bifidobacteria, inhibit pathogens and suppress inflammation in an organoid model.

A new probiotic in development? 🦠👶

Evaluating the analytical performance of direct-to-consumer gut microbiome testing services - Communications Biology Comparative analysis of DTC gut microbiome testing services reveals significant methodological variability, underscoring the need for standardized reference materials and guidelines to ensure reproducibility and reliability in commercial microbiome testing.

Results and health assessments from gut microbiome home-testing kits vary whether they are produced by the same or different manufacturers. The findings, published in Communications Biology, highlight the need for caution when interpreting or acting on test results, according to the authors. 🧪

Metabolic modeling reveals determinants of prebiotic and probiotic treatment efficacy across multiple human intervention trials Prebiotic and probiotic interventions can induce therapeutically relevant shifts in the human microbiome, but their effects are variable across individuals.

This Research Experiences for Undergraduates (REU) program is funded by the National Science Foundation to create "points of entry" for students interested in research. Students apply from across the country to spend 10 weeks in Bozeman, Montana this summer (May 26, 2026 - August 1, 2026). Admitted students are paired with a faculty mentor, who serves as an advisor for a student's summer project. Each student receives a stipend ($7000 for 10 wks). Travel compensation, room, and board are also provided. Our program leverages MSU’s unique microbiology expertise, focusing specifically on microbes living with little or no oxygen (like those in the hot springs of nearby Yellowstone). Low oxygen microbes are essential to human and ecosystem health. They influence (or control) such processes as the breakdown of food in the GI tract, removal of toxins from our bodies and the environment, and production of greenhouse gases. They are also models for understanding the origins of life on this planet, and the potential for life on other planets. A key goal of our program is to recruit students from schools with limited research infrastructure. Being in Montana, a state with a vibrant Native American community, we are particularly interested in applications from students at tribal colleges. However, ANYONE with an interest in microbiology - or biology/science in general - can and should apply. If willing and able, please share/tweet/spread the word far and wide. Applications are due February 14, 2026. Full details can be found through our website http://www.montana.edu/mbi/reu/

Friends, please help spread the word about our microbiology REU program at Montana State University.

Two pieces of fun news:

1. We've launched a new website for our lab: www.brysonlab.org

2. With some new funding, we are recruiting for new postdocs and graduate students. The projects build upon our previous studies of antigen presentation and phagosome biology and go into new exciting dimensions!

Gut microbiota promotes immune tolerance at the maternal-fetal interface Microbiota-dependent tryptophan-derived indole deficiency is linked to mouse fetal resorption and human recurrent miscarriage. Tryptophan-derived indoles prime MDSCs and RORγt+ Tregs to suppress IFN-γ+ or IL-17A+ T cells at the maternal-fetal interface, respectively, thereby promoting maternal-fetal immune tolerance.

Proud to share that three Sinai Genetics and Genomics faculty have been named Clarivate Highly Cited Researchers 2025:
• José Clemente, PhD
• Guo-Cheng Yuan, PhD
• Bin Zhang, PhD
Their work spans #microbiome science, systems #genomics, single-cell biology, and AI-enabled disease modeling.

This has been known for some time, although it's a good reminder. A previous study that comes to mind (www.nature.com/articles/nbt...) found most of the variation was due to extraction methods, while the bioinformatics analysis had a smaller effect.
