Eleven Genetic Regions Shape the Human Gut Microbiome

In two new studies on 28,000 individuals, researchers are able to show that genetic variants in 11 regions of the human genome have a clear influence on which bacteria are in the gut and what they do there.

Study Reveals Planet-Wide Network of Interconnected Microbiomes

In a new study published in Cell, scientists in the Bork Group at EMBL Heidelberg reveal that microbes living in similar habitats are more alike than those simply inhabiting the same geographical region.

Tool Enables Accurate Detection of Microbes in Cancer Genomes

When scientists sequence tumor DNA, they typically find small amounts of genetic code from bacteria, viruses and fungi – microorganisms that, if actually present in tumor tissues, could influence how they grow, evade immunity or respond to treatment.

New CRISPR Tool Actively Reverses Antibiotic Resistance Spread

Antibiotic resistance (AR) has steadily accelerated in recent years to become a global health crisis. As deadly bacteria evolve new ways to elude drug treatments for a variety of illnesses, a growing number of "superbugs" have emerged, ramping up estimates of more than 10 million worldwide deaths per year by 2050.

Formic Acid Drives Novel Electron Transfer in the Gut Bacteria

Researchers at Goethe University Frankfurt have discovered a surprising role for formic acid in the human gut: The small molecule acts as a kind of “taxi” for electrons – both within bacteria and, likely, also between different microorganisms.

Gut Microbial Metabolite Hippuric Acid Amplifies Immune Responses

Scientists at The Wistar Institute have identified a previously overlooked mediator in the body's response to life-threatening infections: hippuric acid, a metabolite produced when gut bacteria break down polyphenols from berries, tea, and other plant-based foods.

Abundance of Oral Microbes Is Strongly Influenced by Genetics

No matter how much they brush their teeth, some people still get more cavities than others, in part because of differences in genetics and the make-up of the microbes in their mouths.

Gut Bacteria Use Protein Injection to Influence Human Immune System

Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses.

Early Social Life Influences Infant Gut Bacteria

Social interaction among babies in their first year of life influences and enriches the diversity of their gut microbial strains, based on the findings of a study on microbiome transmission.

Marsupial Gut Microbiomes Show Diet Adaptations, Antibiotic Resistance Risks

Marsupials are a group of mammals that encompass many of Australia's most iconic animals, unique because of their geographically isolated evolution.

Gut Microbiome Plays a Direct Role in Shaping Brain Function and Evolution

A groundbreaking new study reveals that changes to the gut microbiome can change the way the brain works.

Tumor Bacteria Found to Drive Immunotherapy Resistance

Cleveland Clinic researchers have discovered that bacteria inside cancerous tumors may be key to understanding why immunotherapy works for some patients but not others.

New Rat Study Reveals How Genetic Traits Ripple Through Social Microbiomes

The gut microbiome - made up of trillions of microbes in the digestive tract - is vital for digestion and overall health. Diet and medication shape these microbial ecosystems, but the contribution of genetics has been more difficult to ascertain.

Genes Can Spread Their Effects Through Shared Microbes

Your "roommate's" genes could be influencing the bacteria living in your gut, and vice versa, according to a study of rats published today in Nature Communications.

Specific Gut Bacteria Found to Control Weight and Blood Fat Levels

The gut microbiome is intimately linked to human health and weight. Differences in the gut microbiome-the bacteria and fungi in the gut-are associated with obesity and weight gain, raising the possibility that changing the microbiome could improve health.
