NewsGenetically engineered Bifidobacterium shows potential for oral delivery of cancer vaccines
A novel oral vaccine platform using genetically engineered Bifidobacterium could enhance anti-tumor immunity. In an exploratory phase I clinical study, the vaccine was well tolerated and generated immunologic and clinical findings that warrant further investigation.

NewsPlant-based wound dressing fights infection before it takes hold
A new dressing made from plant-based materials can deliver antibiotics directly to wounds during critical early stages of infection, according to researchers. The study is the first to use this family of sustainable furan-based polymers for infection-fighting wound dressings.

NewsPhytoplankton apply the onion skin principle
The phycosphere, which surrounds ocean microalgae, is one of the most important marketplaces for organic carbon in the oceans. A new study of chemical signals in this region suggests that the phycosphere consists of multiple layers.

NewsThe family tree of viruses just grew – and it paves the way for a new approach to agricultural research
Researchers have discovered that a group of viruses known to infect an agriculturally important plant pathogen has remained genetically stable for an astonishing four decades. The work also led to the classification and naming of the group of phages.

NewsSix years of drought reshape soil microbiomes in tallgrass prairie, study finds
A new study tracking soil microbial communities across six years of experimental drought in a tallgrass prairie finds that prolonged water stress diminishes biodiversity, pushing communities toward less predictable, harder-to-reverse configurations.

NewsAnother tick-borne disease to avoid: anaplasmosis in Canada
Move over, Lyme disease — there’s another tick-borne disease to worry about in Canada. Anaplasmosis, the second most common tick-borne disease in the country, can cause a range of health issues, including myocarditis, as a practice article shows.

NewsWhen a lip ulcer isn’t what it seems: Rare case of syphilis mistaken for mouth injury
Any lip ulcer that is painless, firm, and persists beyond two to three weeks should prompt syphilis testing, even if the presentation does not fit the typical genital picture, warn scientists presenting an unusual case study.

NewsFirst clinical proof of concept for ibuprofen as an adjunctive treatment for tuberculosis
Scientists have published the results of a phase IIa pilot clinical trial assessing ibuprofen as a host-directed therapy in patients with pre-extensively drug-resistant tuberculosis (pre-XDR-TB) and extensively drug-resistant tuberculosis (XDR-TB).

NewsGut bacteria linked to malnutrition may pass to younger generations
A new study suggests that an intestinal disorder linked to malnutrition and stunted growth may be transmitted from one generation to the next via the small intestinal microbiome.

NewsGut bacteria linked to frailty in older women
Researchers have identified clear links between the composition of gut bacteria and frailty in older women. In cases of high frailty, with an increased risk of illness and death, gut bacterial diversity is lower and function is impaired.

NewsGut bacteria boost immune system and help send Vitamin A to T cells
Scientists have discovered that gut bacteria help regulate the development of the body’s immune system by directing the movement of vitamin A through a previously unrecognized cellular network.

NewsResearchers use friendly viruses to tackle inflammatory bowel disease
A research team has developed a targeted approach to treating inflammatory bowel disease (IBD) using bacteriophages, viruses that infect specific bacteria, to disarm harmful microbes without disrupting the broader gut ecosystem.

NewsFood waste treatment can boost renewable energy, but a hidden brown byproduct may be holding it back
Researchers have identified a key chemical obstacle in turning food waste into renewable methane, offering a new semi-quantitative way to track melanoidins and showing that higher doses can severely damage the microbial system.

NewsInternational study maps high risk hotspots of Noma disease in Nigeria
A collaborative international research team has now produced the most detailed mapping of noma incidence risk in Nigeria, uncovering previously unrecognised high-risk areas and providing an important new tool to support prevention and early detection efforts.

NewsWarm temperatures disrupt spider sex-changing bacteria in dwarf-spiders across generations
A new study reveals that exposing dwarf spiders to a brief period of warm temperatures can disrupt a phenomenon where internal bacteria normally force genetic males to develop as females.

NewsGut microbiota can predict risk of type 2 diabetes years before it develops
The presence of certain bacteria in the gut microbiota, and fluctuations in a person’s metabolism, can be seen in people who go on to develop type 2 diabetes years later, paving the way for identifying people at risk of developing type 2 diabetes at an early stage.

NewsA bacterium capable of predicting the course of a disease
A research team made use of the bacterium’s natural capabilities without altering it genetically. Using plasma samples from patients with COVID-19, they were able to distinguish patients likely to develop a mild form of the disease from those at risk of progressing to a severe form.

NewsHow immune cells in our gut mesentery fight salmonella
Researchers have found that immune cells in a portion of the abdominal cavity, called the mesentery, play a critical role in suppressing — or exacerbating — salmonella infection.

NewsBiochar ‘switches on’ natural oxygen chemistry to suppress soil-borne pathogens and reshape healthier microbial communities
A new study reveals how specially prepared biochar can directly suppress a destructive soil-borne pathogen while helping rebuild a richer and more stable soil bacterial community.

NewsDrug candidate treats severe fatty liver disease by protecting the gut in animal models
Researchers discovered that a potential drug treats severe fatty liver disease by improving gut health. It reversed metabolic dysfunction-associated steatohepatitis (MASH) in animal models by disrupting a disease-driving pathway that links the gut and liver.
