NewsEngineered bacteria unlock seaweed potential: dual enzyme system enables complete alginate depolymerization
A research team has heterologously expressed alyB and alyD genes from the marine bacterium Vibrio algivorus in C. glutamicum, an industrial workhorse traditionally used for amino acid production.

NewsUnlocking how dogs’ fungal ear infections evade treatment points vets to drug stewardship
Mutations in a key protein make a yeast found in dogs with common outer ear infections more resistant to the topical antifungals used to treat it, veterinarians and pathobiologists found in a new study.

NewsTurmeric/ginger extract shows multiple benefits for bone implants
An extract of turmeric and ginger helps bone implants bond strongly while killing bacteria and cancer cells, according to new research with implications for millions of patients with joint replacements and bone cancer.

NewsDrones, DNA, and weather: A phase-oriented hybrid engine to predict sugar beet disease
A fungus that can wipe out up to 50% of a sugar beet crop may soon meet its match in a new generation of smart disease forecasting. Combining drone imagery, weather data, and qPCR-based airborne spore monitoring can reveal where disease is present and what the pathogen is likely to do next.

NewsLoss of microbiota alters the profile of cells that protect the intestinal wall
Experiments in mice and human tissue indicate that a reduction in bacteria living in the large intestine decreases mucus production and affects nutrient absorption, particularly in older adults.

NewsHIV infections would increase by 10% average if CDC funding for HIV testing ends, study predicts
Researchers used a computer model to quantify the effect of funding cuts for HIV testing. They estimate that HIV infections could increase an average of 10% in 18 U.S. states if this funding is interrupted or ended.

NewsNew biochar composite tackles arsenic pollution and methane emissions in rice paddies
Rice paddies feed more than half of the world’s population, yet they are also hotspots for toxic arsenic contamination and greenhouse gas emissions. A promising solution that addresses both problems at once uses an engineered biochar material enhanced with titanium dioxide.

NewsCorner-loving single-celled microorganism uses geometry to sense its world
A surprising observation in the lab has revealed a remarkable ability in Stentor coeruleus, a single-celled organism about one millimeter long. Sometimes nicknamed the “platypus” of microorganisms for its trumpet-like shape, this tiny creature appears to have a distinct preference for corners.

NewsBlood test using artificial intelligence paves the way for early diagnosis of leprosy
A new blood test combined with a standardized questionnaire and artificial intelligence may transform the way leprosy is diagnosed in Brazil. The method showed potential for identifying the disease in its initial stages, when symptoms are subtle and traditional laboratory tests often fail.

NewsBacteria incorporate forever chemicals into cell membrane molecules
New research shows that bacteria incorporate polyfluoroalkyl carboxylates—a type of Per- and Polyfluoroalkyl Substances (PFASs)—into the molecules that make up their cell membranes.

NewsMicroscopic coils and coffee trees lead to an amazing new fungal discovery
A new study has revealed two novel species of Neohelicomyces fungi: Neohelicomyces coffeae and Neohelicomyces puerensis. While studying the fungi that live on Coffea arabica, researchers spotted these unique organisms growing on dead coffee branches.

NewsInuit recommendations to address high rates of tuberculosis in Nunavik, Quebec
Tuberculosis rates for Inuit living in Nunavik, the Inuit lands in northern Quebec, are 1,000 times greater than among non-foreign-born Quebeckers, and underresourcing of local health care adds to hardship from the disease, found new research.

NewsA new mouse model of virus-driven liver cancer may open the door to better diagnosis and treatments
Researchers have created the first mouse model in which chronic viral infection progresses to liver cancer, closely mirroring what happens in people with hepatitis C.

NewsFungi hold the key to boosting urban soil health with biochar and compost
A new study reveals that combining biochar and compost can restore soil health in urban green spaces, but only under the right conditions, and fungi play a decisive role in determining success.
-
NewsNovel treatment protocol targets the deadliest cases of C. difficile infection
A new study demonstrated that fecal microbiota transplantation (FMT) can rapidly reverse systemic inflammation and improve survival in patients with fulminant Clostridioides difficile infection.

NewsA world within the leaves: Sign up for our fascinating free webinar
A single tree can harbour hundreds of species - yet few people will realise that some of those species live within the very leaves themselves. A fascinating free webinar will explore the fascinating world of fungal communities that live inside leaves.

News New virulence regulator of diarrhea pathogen discovered
While it was already known that RNA molecules enable direct temperature sensing in the model organism Yersinia pseudotuberculosis, a new study reveals that the Fis protein also plays a regulatory role at the DNA level.

NewsShiitake-derived β-glucan inhibits human cervical cancer progression through DMBT1
A team of researchers investigated the molecular mechanism underlying the anti-cervical cancer activity of Lentinus edodes-derived β-glucan (LNT) and, for the first time, identified DMBT1 as a key target.

NewsNew strategy to break resistance-yield trade-off in rice by pathogen-inducible gene expression
A research team has developed a genetic strategy to enhance broad-spectrum disease resistance in rice without compromising plant growth and yield, a major challenge in crop breeding.

NewsHigh‑fat diets linked to rapid decline in protective gut immune cells
In a preclinical study, researchers found that even short-term exposure to high levels of dietary fat results in a quick and selective loss of critical gut immune cells called ILC3s, promoting intestinal permeability and inflammation.
