A new SELF feature highlights research showing that bowel movement frequency — particularly one to two times per day — may be linked to overall health, including gut microbiome balance and toxin levels. ISB’s Sean Gibbons explains why this “Goldilocks zone” could signal optimal physiology.

Researchers in the Gibbons Lab used computer models of gut metabolism to predict which probiotic strains will successfully establish in an individual’s microbiome and how prebiotics influence beneficial molecule production, a step toward more personalized microbiome-based interventions.

A study led by researchers in ISB’s Gibbons Lab found that bowel movement frequency is linked to differences in gut microbiota and subtle changes in blood chemistry, suggesting that both infrequent and overly frequent defecation may relate to microbiome balance and toxin exposure risk.

Dr. Mary Brunkow tops Seattle Magazine’s “Most Influential” list, highlighting leaders shaping culture and community. The profile recognizes her groundbreaking scientific contributions and local impact, situating her alongside innovators across fields in this annual Seattle spotlight.

Lee Hood was ranked #41 on Forbes’ “250 America’s Greatest Innovators” list, published in celebration of America’s 250th anniversary. The list highlights individuals whose scientific leadership, creativity, and impact are shaping the future of science and innovation — and recognizes Hood’s lasting contributions to research and discovery.

ISB Postdoc Nathaniel (Nate) Ritz, Ph.D., was named a 2026 WRF Postdoctoral Fellow, receiving three years of support from the Washington Research Foundation to advance technology that decodes gut microbiota-host chemical communication. The award is part of WRF’s statewide program backing early-career scientists pursuing high-impact research.
