Here are some of my thoughts on how to feed the gut microbiome 🧪 based on learnings from our research

What a gut microbiome scientist wants you to eat every day Focus on eating fiber-rich foods, especially those high in a special type of fiber called resistant starch.

I was able to share some of the learnings about diet choices for a happy and well-fed gut microbiome!🧪

Based on our work exploring how diet, the human host, and gut microbes interact to impact energy balance.

Join the National Academies Board on Science Education for a one-day hybrid event that will bring together leaders across domains to discuss the key insights and recommendations from the recently released consensus study report, Understanding and Addressing Misinformation about Science, and identify opportunities for multi-sectoral action. This report is a comprehensive assessment of the available evidence on the nature, scope, and impacts of misinformation about science and reflects a systems view of the phenomenon given the broader contexts and challenges that shape people’s lived experiences and their relationships to information. The report also provides guidance on interventions, policies, and future research toward mitigating potential harms from misinformation about science across a diversity of individuals, communities, and societies. DATE Sep 25, 2025 9:15AM - 3:30PM ET LOCATION Keck Center 500 5th St NW Washington DC 20001 USA

Sept 25th marks a free 1-day symposium on "Understanding & Addressing Misinformation About Science," including opportunities for coordinated multi-sector action. In-person + virtual participation available: www.nationalacademies.org/event/45553_...

Congratulations!!!

Totally. I deleted my bird app account and have never looked back.

As one can imagine, I have some thoughts. Here’s a thread no one asked for:

1. SCIENCE IN THE US IS POLITICAL. No matter how much you want to ignore that fact, it is supported by taxpayer dollars and is therefore, political by nature.

2. BUT it has had bipartisan support for decades, which…

Metagenomic estimation of absolute bacterial biomass in the mammalian gut through host-derived read normalization | mSystems In this study, we asked whether normalization by host reads alone was sufficient to estimate absolute bacterial biomass directly from stool metagenomic data, without the need for synthetic spike-ins, ...

You can get an accurate estimate of total bacterial biomass from stool metagenomes by simply normalizing by host read count, without needing any additional measurements.

DO NOT GIVE UP!

Our advocacy is working.

A key Senate committee has indicated that it will reject Trump’s proposed cuts to science agencies including NASA and the NSF.

Thank you! It was an interesting hypothesis with much left to uncover.

Hypotheses and overall findings

Overall- we uncovered novel hypotheses related to a gut-adipose-liver axis that should be tested in future studies that focus on a broader range of MASLD physiology and evaluate people with and without diabetes and obesity.

Gene modules related to adipose insulin resistance and encroachment.

We did not find differences in biomarkers of gut permeability or colon histology (by group or overall). What we did find were colonic gene modules that were correlated with adipose insulin resistance encroachment.

Insulin resistance between groups

We found a range of encroachment from low to high- similar to what has been seen in people w diabetes/obesity. It could be that insulin resistance is a key driver since all participants had obesity. We then set out to determine what might distinguish high vs low encroachment.
