Summary
Microbiology is the study of the invisible majority of life on Earth: bacteria, archaea, fungi, protozoa and viruses. These organisms underpin global nutrient cycles, drive ecosystem stability and shape the health of plants, animals and humans. Microbial ecology has revealed that communities in soils, oceans and the human body respond to chemical gradients and environmental change through metabolic interactions, cross‐kingdom signalling and collective behaviours such as biofilm formation. At the molecular level, advances in genomics and single-cell techniques have uncovered the genetic and regulatory networks that govern microbial adaptation, from chemolithotrophy in deep-sea vents to symbioses in the rhizosphere. Host–microbe interactions range from beneficial immune modulation to pathogen evasion strategies and the emergence of antimicrobial resistance. As global challenges—from climate change to food security and emerging infections—intensify, microbiology offers insights and technologies for bioremediation, sustainable agriculture, novel therapeutics and vaccine development, highlighting its central role in a healthy and resilient planet.
Research from Nature Portfolio
Recent studies have shown that a novel species, Sulfurimonas pluma, dominates cold, oxygen-rich hydrothermal plumes worldwide. Genome sequencing revealed a streamlined metabolism relying on hydrogen-driven aerobic chemolithotrophy, with specialised cytochromes that optimise carbon fixation and sulphur cycling under extreme conditions. In parallel, work on the intestinal microbiota has demonstrated that a specific short-chain fatty acid, pentanoate, enhances iron uptake by regulatory T cells through upregulation of transferrin receptors. This mechanism restores T-cell homeostasis and mucosal tolerance in models of colitis, linking microbial metabolites to immune regulation and nutrient absorption. A global survey of vineyard soils has further illustrated how spatial distance and climate shape core bacterial and fungal taxa, defining region-specific “microbial terroirs” that correlate with soil properties and wine characteristics.

About these summaries
This Nature Research Intelligence Topic summary is created with the cited references and a large language model. We take care to ground generated text with facts, and have systems in place to gain human feedback on the overall quality of the process in line with our AI principles. We strive to create accurate and useful summaries for people unfamiliar with the research topic and that supports this goal. These pages are a beta release and will be updated as we learn how best to help people gain value from a research topic summary.
