Microbes sense neighbors and change jobs to reduce competition, offering clue to coexistence

Phys · · 641 words · By Ben-Gurion University

New research published in Nature Microbiology indicates that microbes do not function in isolation but actively sense and adjust their behavior when living together. The study suggests that the identity of neighboring microbes can influence protein production more than the food source alone, providing a new model for understanding how diverse microbial communities coexist. These findings have implications for developing advanced therapies, such as probiotics and agricultural interventions, by focusing on community composition rather than single species.

“New research from Ben-Gurion University of the Negev, published in Nature Microbiology, reveals that when microbes live together, they can sense one another and actively reduce competition by shifting toward different roles instead of all doing the same thing.”
CORROBORATED
Multiple web search results confirm that microbes sense neighbors and adjust their behavior to reduce competition. Specifically, the evidence mentions that researchers found microbes can detect each other's presence and adjust their behavior to minimize direct overlap and improve coexistence.

“In nature, many species coexist within the same community, even though based on their genomic potential, they are often expected to compete aggressively for similar resources, and in theory could eliminate one another.”
SINGLE SOURCE
The web search results provided are general articles about scientific journals (Nature, Nature Reviews) and do not contain the specific context or evidence needed to corroborate the claim about species coexisting despite potential for aggressive competition. The evidence is irrelevant to the claim.

“A microbe is not defined only by its genome, which represents its potential, but also by its community.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. Although the surrounding context (Claims 6 and 7) implies this concept, the specific claim that 'A microbe is not defined only by its genome... but also by its community' was not directly supported by the search results.

“In human health, it suggests that designing probiotics or microbiome-based therapies is not just about choosing the 'right' microbes. It is about finding the right combinations, communities where microbes naturally divide tasks instead of competing or duplicating effort.”
INSUFFICIENT EVIDENCE
No evidence was gathered for this claim. Although the surrounding context (Claim 3) suggests this implication, the specific claim regarding designing microbiome therapies based on optimal community combinations was not directly supported by the search results.
