NewsLow-cost preventive measures could mitigate spread of bacteria causing neonatal mortality
A new study found that a multifaceted infection prevention and control intervention could at least temporarily thwart outbreaks of infections from the Klebsiella pneumoniae bacterium.

NewsSpecific gut bacteria species linked to muscle strength
A species of gut bacteria called Roseburia inulinivorans is specifically associated with human muscle strength and improved muscular performance in mice, finds new research. R inulinivorans changes certain metabolic processes in muscle, and converts muscle fibres to ‘fast-twitch’ (type II).

NewsGut bacteria drive process that protects colon tissue
Researchers have shown that the identity of distinct regions of the colon are regulated by the gut microbiome. They identified nicotinic acid, a molecule produced by certain bacteria in the gut microbiome, as a main driver of these regional differences in the colon’s sections.

NewsFrom microbial processes to biofilm control: our interview with JAM Microbial Biotechnology lead editor Manuel Simões
Professor Manuel Simões, Deputy Editor of the Journal of Applied Microbiology, has just been appointed as the journal’s new lead editor in Microbial Biotechnology. Here’s why he’s looking forward to the challenge.

NewsAntibiotic resistance can vary depending on where the bacteria live
Antibiotic susceptibility in resistant bacteria is not static. New research shows that bacteria harbouring resistance genes may respond differently to antibiotics if they are tested under conditions other than those used in standard laboratory assays.

NewsTeam simulates a living cell that grows and divides
By simulating the life cycle of a minimal bacterial cell — from DNA replication to protein translation to metabolism and cell division — scientists have opened a new frontier of computer vision into the essential processes of life.

NewsStay or stray? Scientists discover why some gut microbes persist after fecal transplants
Scientists have identified why some gut microbes successfully stay in the gut after faecal transplants, whilst others are much more transient. They tracked key genetic features of gut bacteria in 86 healthy adults over the course of a year.

NewsStudy investigates how microbes use ancient carbon
Researchers investigated a hydrothermal vent system at a depth of about ten meters off the coast of Kueishantao island in Taiwan. They tracked the path of this carbon in the surrounding sea and its uptake by microorganisms and other living things.

NewsWhen rats run, their gut bacteria rewrite the chemical conversation with the brain
A new study suggests that exercise stimulates a molecular link between gut bacteria and the brain. The research examined what happens to the gut microbiota, circulating metabolites, and hippocampal gene expression when rats are given free access to a running wheel for eight weeks.

NewsTiny vesicles, big risk: Environmental sweeteners trigger antibiotic resistance transfer
A new study reveals that mixtures of artificial sweeteners can stimulate soil bacteria to release microscopic extracellular vesicles that carry antibiotic resistance genes (ARGs).

News‘Bugs delivering drugs’ – new approach to colorectal cancer treatment using common food-borne bacteria
Researchers have published a novel approach to fight colorectal cancer, using modified bacteria as a courier to deliver potent cancer-killing proteins into tumor cells.

NewsHitchhiking bacteria can alter marine snow's role as a carbon sink
Researchers have found that when bacteria hitch a ride on marine snow particles, the microbes can eat away at calcium carbonate, which is an essential ballast that helps particles sink.
-
NewsShifting from biotic to abiotic drivers of urban microbial multifunctionality under drought and rehydration
Scientists conducting microcosm experiments on Zoysia japonica, a common urban turfgrass, simulated four drought intensities and recovery by rehydration. They analyzed alteration in microbial communities and biochemical cycling to pinpoint the drivers of urban microbial multifunctionality.

NewsNew studies reveal how Clostridioides difficile behaves inside the body
Researchers studying C. diff at multiple levels, from how individual bacterial cells behave inside the gut to the molecular switches that help them survive and spread, are revealing hidden vulnerabilities.
-
NewsNew compound stops common complications after intestinal surgery
Researchers have synthesized and tested a new compound in mice that shows promise in protecting the liver from damage and improving nutrient absorption after small bowel resection. They also found that the drug works only on the gastrointestinal tract.

NewsScientists engineer ‘living eye drop’ to support corneal healing
A proof-of-concept study demonstrates that the harmless eye-dwelling microbe Corynebacterium mastitidis can be genetically modified to secrete an anti-inflammatory therapeutic that promotes healing following corneal injury in a mouse model.

NewsHow microbes protect the lungs against allergies
A study has revealed that microbes protect the lungs from subsequently developing allergies and asthma. This long-term protection is “memorized” not by immune system cells but by fibroblasts, structural cells in the lungs.

News Natural dye produced by Amazonian fungus can be used in cosmetics
A red extract made from Talaromyces amestolkiae was tested in the bases of potential products, including face cream, shampoo, and gel sticks, for its antioxidant and antibacterial properties.
-
NewsStudy reveals how gut bacteria and diet can reprogram fat to burn more energy
A new study shows that a low‑protein diet activates a precise set of gut microbes that send chemical signals throughout the body, prompting fat tissue to burn energy instead of storing it. The findings uncover a previously unknown biological pathway linking diet, the gut microbiome and metabolic health.

NewsNitrous oxide, a product of fertilizer use, may harm some soil bacteria
While some nitrous oxide is produced naturally at the plant root, agricultural practices can increase its levels. While it has long been believed that nitrous oxide doesn’t meaningfully interact with living organisms, a new paper shows that it may in fact shape microbial communities.
