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.

Scalp Microbiome Explained: What’s Living on Your Scalp and Why It Matters

The scalp microbiome comprises diverse bacteria, fungi, and yeast that interact with sebum, pH, and immune responses to maintain scalp health. Microbial imbalances are increasingly linked to conditions such as dandruff, hair loss, and inflammation, making the scalp microbiome a target for novel therapeutic approaches.

AI spots hidden diabetes risk even when test results look normal

Researchers used continuous glucose monitoring and multimodal data from over 3,000 people to reveal hidden patterns in glucose spikes across normoglycemia, prediabetes, and type 2 diabetes. Their AI-driven model exposed high individual variability and offers a personalized path for early detection and prevention of diabetes.

Beneficial gut bacteria found to suppress harmful microbes

Intestinal bacteria are important for human health as they help digest food and regulate immune function. Thus, in recent years, it has become clear that gut microbiota dysbiosis, an imbalance in types and composition of intestinal bacteria, is associated with digestive disorders and other diseases.

New research reveals why fiber-rich diets fuel you better than refined foods

This study quantifies how much energy the human body harvests from gut microbial fermentation of dietary fiber, integrating bacterial physiology, diet, and metagenomic data. Results reveal that dietary fiber, not microbiome composition, mainly determines the amount of short-chain fatty acids absorbed, impacting daily energy and metabolic health.

Immunocompromised people are susceptible to skin cancer caused directly by beta-HPV

Researchers at the National Institutes of Health (NIH) have shown for the first time that a type of human papillomavirus (HPV) commonly found on the skin can directly cause a form of skin cancer called cutaneous squamous cell carcinoma (cSCC) when certain immune cells malfunction.
