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).

NewsNew African species confirms evolutionary origin of magic mushrooms
A long-standing debate about the evolutionary origin of the world’s most widely cultivated ’magic mushroom’ – Psilocybe cubensis – may now have been settled. Scientists describe the discovery of a new species of magic mushroom from the grasslands of South Africa and Zimbabwe.

NewsBuilding protection against infectious diseases with nanostructured vaccines
Researchers have leveraged a recently developed highly versatile DNA origami nanotechnology that is both vaccine and adjuvant, named DoriVac, as an alternative to current vaccine platforms.

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.

NewsResearchers uncover hidden genetic world in Antarctic Waters
Researchers have completed the most comprehensive survey to date of DNA associated with Southern Ocean microbes, paving the way for a better understanding of their role in climate change. At least a third of the genes identified are missing from existing marine gene catalogs.

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.

NewsMachine learning reveals when biochar helps or harms soil life
Researchers have shown that biochar can either help or harm soil organisms depending on how it is produced and applied. The research analyzed results from dozens of previous experiments to better understand how biochar affects plants, microbes, and soil animals.

NewsNew study finds deep ocean microbes already prepared to tackle climate change
A new study demonstrates that the microbe Nitrosopumilus maritimus may already be adapting well to warmer, nutrient-poor waters. Researchers predict that these adaptable iron-dependent ammonia-oxidizing archaea will play an important role in reshaping ocean-nutrient distribution in a changing climate.

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.

NewsScientists trace crop viruses back to the last Ice Age
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. Tthe ancestors of modern tymoviruses likely emerged before the last Ice Age, a new study reveals.

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.

NewsEnteroBiotix announces completion of enrolment in Phase 2a Trial evaluating EBX-102-02 prior to allogeneic stem cell transplantation
EnteroBiotix announced that the investigator-initiated Phase 2a MAST trial has completed its enrolment of 50 adult patients undergoing allogeneic haematopoietic stem cell transplantation (allo-HSCT) for defined haematological malignancies.

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.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

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.

NewsMpox immune test validated during Rwandan outbreak
An antibody test for the infectious disease Mpox was successfully developed during the new clade 1b outbreak in Rwanda, the first time that an assay of its kind has been validated within this setting.
