Microbiome

The varied community of microorganisms that live in different parts of the body, particularly the gut, is referred to as the human microbiome. These microorganisms are mostly bacteria, but they can also be viruses, fungi, and archaea. These microbial communities are vital for immune regulation, nutrition synthesis, digestion, and pathogen defense. Metagenomics research has shown that homeostasis depends on a healthy, diverse microbiome, whereas dysbiosis, or imbalances in the microbiome, is linked to a variety of illnesses, such as obesity, inflammatory bowel disease, allergies, and neuropsychiatric disorders. The field of microbiome research is growing quickly, providing new information on diet-microbe interactions, probiotic treatments, and personalized medicine.

Supportive marriages may shape appetite control through oxytocin and the brain–gut axis

Supportive marital relationships are associated with lower BMI, fewer food addiction symptoms, higher oxytocin, stronger frontal brain responses to food cues, and favorable gut tryptophan metabolites. These coordinated social, neural, hormonal, and gut pathways suggest a plausible biological link between emotional support and healthier eating regulation.

Industrial and farm chemicals quietly alter the balance of gut microbes

This study systematically screened over 1,000 agricultural and industrial chemicals and found that many can inhibit human gut bacteria in vitro. Beyond antimicrobial effects, these chemicals act as selective pressures that can reshape microbial competition, tolerance mechanisms, and metabolic pathways.

Lubiprostone shows signs of slowing kidney function decline in chronic kidney disease

In adults with stage IIIb–IV chronic kidney disease, the constipation drug lubiprostone did not reduce gut-derived uremic toxins but preserved creatinine-based kidney function over 24 weeks. The benefit was linked to microbiome remodeling, increased polyamine production, and improved mitochondrial function rather than toxin lowering.

Researchers discover a surprising ally in the fight against insulin resistance and type 2 diabetes

An international research team led by Professor Marc-Emmanuel Dumas at Imperial College London & CNRS together with Prof. Patrice Cani (Imperial & University of Louvain, UCLouvain), Dr. Dominique Gauguier (Imperial & INSERM, Paris) and Prof. Peter Liu (University of Ottawa Heart Institute) has uncovered a surprising ally in the fight against insulin resistance and type 2 diabetes: a microbial metabolite called trimethylamine (TMA).

International collaboration develops STREAMS to standardize microbiome data

Microbiomes, the communities of microorganisms that live in and around us, play a vital role in everything from human health to soil fertility and climate regulation. But studying these tiny life forms, especially outside the human body, presents a major challenge: how do scientists share complex data across such a wide range of environments and disciplines?
