Scientists studying genetic data from over a quarter million people have uncovered new clues about what controls how fast the gut moves. They identified multiple DNA regions linked to bowel movement frequency, confirming known gut pathways and ...
A new study suggests that micro-doses of THC could help counter many long-term side effects of HIV treatment without causing intoxication. In animal models, low-dose THC reduced inflammation, improved gut bacteria, boosted serotonin, and lowered ...
Scientists have uncovered a surprising reason why some chronic wounds refuse to heal, even when treated with antibiotics. A common bacterium found in long-lasting wounds does not just resist drugs. It actively releases damaging molecules that ...
A familiar mouth bacterium best known for causing cavities may also be quietly influencing the brain. Scientists found that when this microbe settles in the gut, it produces compounds that can travel through the bloodstream and harm neurons involved ...
New research shows gut bacteria can directly influence how the brain develops and functions. When scientists transferred microbes from different primates into mice, the animals’ brains began to resemble those of the original host species. Microbes ...
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 ...
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. ...
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 ...
Sorbitol, a popular sugar-free sweetener, may not be as harmless as its label suggests. Researchers found it can be turned into fructose in the liver, triggering effects similar to regular sugar. Gut bacteria can neutralize some of it—but too much ...
Researchers discovered that 168 common chemicals can disrupt the growth of beneficial gut bacteria, with some also promoting antibiotic resistance. Many of these substances—found in food, water, ...
Scientists in Seoul have uncovered 15 gut bacterial species linked to coronary artery disease, showing that microbes can influence heart health far beyond digestion. Their findings reveal how shifts in gut microbial function — including ...
Researchers have, for the first time, estimated how quickly E. coli bacteria can spread between people — and one strain moves as fast as swine flu. Using genomic data from the UK and Norway, scientists modeled bacterial transmission rates and ...

A study has become the first in the world to unravel the immediate effects of a high-fat diet on our gut ...

Researchers show how mice fed a Western-style diet are not able to rebuild a 'healthy,' diverse gut microbiome following antibiotic treatment. These mice were also more susceptible to ...

A new approach to drug design can deliver medicine directly to the gut in mice at significantly lower doses than current inflammatory bowel disease treatments. The proof-of-concept study introduced a ...

After spending years tracing the origin and migration pattern of an unusual type of immune cell in mice, researchers have shown in a new study how activity of 'good' microbes in the gut is ...

Scientists inserted DNA-encoding methylmercury detoxification enzymes into the genome of an abundant human gut bacterium. The engineered bacterium detoxified methylmercury in the gut of mice and ...

Protein sources appear to have major effects on both the population and function of the mouse gut ...

Scientists built a model that allows them to diminish phage communities from a mouse gut microbiome -- and then bring them back -- without affecting the bacteria. On a test run of their model, ...

The global burden of chronic kidney disease (CKD) is rising, with more than 800 million people affected worldwide. Vascular diseases in patients with CKD are unique and grouped as uremic vascular ...

Scientists have discovered a surprising new connection between gut health and blood cancer risk one that could transform how we think about aging, inflammation, and the early stages of ...

Researchers have made significant advancements in understanding the earliest stages of stomach cancer, a leading cause of cancer-related deaths worldwide, through two recent innovative studies. With ...

Bacteria naturally present in the human intestine (known as the gut microbiota) can transform cholesterol-derived bile acids into powerful metabolites that strengthen anti-cancer immunity by blocking ...

Could a gene regulatory network in gut microbes have evolved its elaborate and tightly regulated molecular machinery only to pump out antibiotics indiscriminately? Researchers show this is an ...

Scientists have discovered how a diarrhea-causing strain of bacteria uses 'molecular scissors' to cut open and destroy gut cells, leading to severe illness and sometimes ...

A new study shows how common gut bacteria can metabolize certain oral medications that target cellular receptors called GPCRs, potentially rendering these important drugs less ...

An AI model trained on large amounts of genetic data can predict whether bacteria will become antibiotic-resistant. The new study shows that antibiotic resistance is more easily transmitted between ...

A new study examined whether a specialized diet could improve symptoms of gastrointestinal disorders linked to an imbalance in gut ...

The pathogen C. diff -- the most common cause of health care-associated infectious diarrhea -- can use a compound that kills the human gut's resident microbes to survive and grow, giving it a ...

Scientists have systematically analyzed somatic mutations in stomach lining tissue to unpick mutational processes, some of which can lead to cancer. The team also uncovered hints of a potential new ...

Researchers conducted a large-scale online survey of clinicians in the Asia-Pacific region to investigate treatment policies for the gastric cancer-causing bacteria Helicobacter ...

Increased antibiotic use can lead, seemingly paradoxically, to more problematic infections, as the bacteria evolve to resist the treatment. The answer to this antimicrobial resistance, which the ...
