Oral bacteria may signal metabolic health and even contribute to obesity
It turns out your mouth may know more about your metabolism than your bathroom scale. New research shows that people with obesity host a distinct oral microbiome compared to individuals at a healthy weight. Rather than zeroing in on the gut microbiome, the study turns our attention to the mouth as a potential biological signal of metabolic health. It’s a shift that could challenge long-held assumptions about where obesity-related biomarkers can be measured.
Scientists discover a hidden gut bacterium linked to good health
A global study has uncovered a mysterious group of gut bacteria that shows up again and again in healthy people. Known as CAG-170, these microbes were found at lower levels in people with a range of chronic diseases. Genetic clues suggest they help digest food and support the broader gut ecosystem. Researchers say the discovery could reshape how we measure and maintain gut health.

Overlooked group of gut bacteria appears key to good health, global study finds
In a huge global study led by University of Cambridge researchers, a single group of bacteria—named CAG-170—has repeatedly shown up in high numbers in the gut microbiomes of healthy people. CAG-170 ...
Gut bacteria can sense their environment and it’s key to your health
Your gut is home to trillions of bacteria that constantly “sense” their surroundings to survive and thrive. New research shows that beneficial gut microbes, especially common Clostridia bacteria, can detect a surprisingly wide range of chemical signals produced during digestion, including byproducts of fats, proteins, sugars, and even DNA. These microbes use specialized sensors to move toward valuable nutrients, with lactate and formate standing out as especially important fuel sources.
Scientists discover how to turn gut bacteria into anti-aging factories
Researchers found that small doses of an antibiotic can coax gut bacteria into producing a life-extending compound. In worms, this led to longer lifespans, while mice showed healthier cholesterol and insulin changes. Because the drug stays in the gut, it avoids toxic side effects. The study points to a new way of promoting health by targeting microbes rather than the body itself.
These four common foods may be wrecking your gut health, expert warns
Common kitchen foods may be damaging your gut health without you knowing it. A nutrition expert reveals four surprising culprits harming your microbiome.
Exhaled breath may carry clues to gut microbiome health
The human gut is home to trillions of beneficial microbes that play a crucial role in health. Disruptions in this delicate community of bacteria and viruses—called the gut microbiome—have been linked ...
Why your gut microbiome is so important for health and how to protect it
Bacteria in the gut perform important jobs that help prevent disease, but how to best protect and improve yours? An expert weighs in.
Science army mobilizes to map U.S. soil microbiome

Everyday chemicals are quietly damaging beneficial gut bacteria
A large study has revealed that dozens of widely used chemicals can damage beneficial gut bacteria. Many of these substances, found in pesticides and everyday industrial products, were never thought to affect living organisms at all. When gut bacteria are stressed by these chemicals, some may also become resistant to antibiotics. The research raises new questions about how chemical exposure could be influencing human health behind the scenes.

This common food ingredient may shape a child’s health for life
Scientists discovered that common food emulsifiers consumed by mother mice altered their offspring’s gut microbiome from the very first weeks of life. These changes interfered with normal immune system training, leading to long-term inflammation. As adults, the offspring were more vulnerable to gut disorders and obesity. The findings suggest that food additives may have hidden, lasting effects beyond those who consume them directly.

Your roommate’s genes may be shaping your gut bacteria
Scientists studying thousands of rats discovered that gut bacteria are shaped by both personal genetics and the genetics of social partners. Some genes promote certain microbes that can spread between individuals living together. When researchers accounted for this social sharing, genetic influence on the microbiome turned out to be much stronger than previously thought. The study suggests genes can affect others indirectly, without DNA ever being exchanged.
What your mouth can reveal about your health
Scientists are discovering that the oral microbiome—home to hundreds of species of bacteria and fungi—may help predict everything from cancer risk to heart and brain health.
We may finally know what a healthy gut microbiome looks like
