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.

NewsStudy writes the catalog of plasma membrane repair proteins
A new study identifies 80 proteins involved in plasma membrane repair in budding yeast, laying the foundation for membrane repair studies and future therapeutic applications.

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.

NewsResearchers make probiotic safer for immunocompromised patients
Researchers have modified a probiotic yeast to make it safer for use by immunocompromised people, older adults and infants. Testing in an animal model found the modified yeast is less likely to cause infection than unmodified strains of the same organism.

NewsStudy highlights gut–brain axis in pituitary tumor–related cognitive decline
Researchers conducted a prospective cross-sectional study to evaluate cognitive function in patients with pituitary neuroendocrine tumors and examine associations among tumor lineage, hormonal abnormalities, and gut microbiota composition.

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.

NewsGut microbes rewrite the rules of cancer immunotherapy
A review synthesizes growing evidence showing that commensal microbes enhance anti-tumor immunity by producing immune-active metabolites, remodeling the tumor microenvironment, and activating key immune cells such as dendritic cells and cytotoxic T cells.

NewsMicrobe exposure may not protect against developing allergic disease
The “hygiene hypothesis” suggests exposure to diverse types of microbes may protect against developing diseases caused by allergens, but a new study in mice reveals that adults’ exposure to diverse microbes and allergens may in fact worsen certain allergic conditions.

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.

NewsSoybeans recruit beneficial soil microbes to defend against major pest
Researchers report that resistant soybean varieties actively recruit beneficial soil microorganisms that help suppress soybean cyst nematode. Even more striking, those protective microbes can be transferred to soil to help defend susceptible soybean plants.

NewsHerpes virus fluidizes cell nuclei to multiply faster
A new study finds that herpes simplex virus uses a protein called infected cell protein 4 (ICP4) to make the human nucleus more fluid-like, which in turn makes it easier for the virus to replicate itself. Blocking the ability of ICP4 to fluidize the nuclear compartment caused a drop in viral copy production.

NewsScientists successfully harvest chickpeas from ‘moon dirt’
Scientists have successfully grown and harvested chickpeas using simulated “moon dirt,” the first instance of this crop produced in this medium. They added vermicompost and coated the chickpeas with the fungi arbuscular mycorrhizae before planting.

NewsArtificial feeding platform transforms study of ticks and their diseases
The world’s first lab-based tick feeding system for bush ticks has transformed the study of ticks and how they transmit disease. The novel, host-free technology reduces the need for animal experiments in tick studies, facilitating more ethical, reproducible research.
