NewsStudy sheds new light on what drives evolution of gut microbiomes
A study of wild African herbivores offers new insight into how environmental conditions – not just diet and anatomy – can influence the evolution of gut microbes that play a critical role in animal health and well-being.

NewsResearchers discover a previously unknown bacterial component in kidney stone formation
In an unexpected finding, scientists have discovered that bacteria are present inside the most common type of kidney stone, revealing a previously unrecognized component involved in their formation. The findings point to a possible therapeutic target that could be used for prevention and treatment.

NewsEarly warning for wine spoilage glows in the dark
Researchers have built a living biosensor made of bacteria that lights up when it detects acetic acid, the main chemical signal that wine is starting to spoil. It works in real time, even in high-alcohol conditions, so wineries can catch problems early, before flavor and quality are damaged.

NewsEpigenetic switch strengthens plant immunity against downy mildew
Researchers investigating how epigenetic regulators influence resistance to downy mildew in Brassica rapa identified BrHDA6 as a positive regulator of disease resistance and demonstrated that it enhances immunity by modifying a key enzyme in salicylic acid metabolism.

NewsStudy suggests link between viral infection and ALS
Researchers have made a potentially game-changing discovery about the development of devastating motor neuron diseases. They identified a specific type of mouse — the CC023 strain — that responds to a viral infection in a way that looks remarkably similar to humans with amyotrophic lateral sclerosis.

NewsMore than just gut cohabitants: how gut bacteria control immune responses
Bacteria in the human gut can directly deliver proteins into human cells, actively shaping immune responses. The study reveals a new way in which the gut microbiome can influence the human body and may help explain how changes in gut bacteria contribute to inflammatory diseases.

NewsTracking antibiotic resistance in the environment gets a high tech upgrade
Antibiotic resistance is often framed as a hospital problem, but a growing body of evidence shows that the environment plays an equally critical role in the global spread of drug resistant bacteria. Rivers, soils, wastewater, and even the air can act as reservoirs for antibiotic resistance genes that may eventually ...

News3′UTR-derived small RNA couples acid resistance to metabolic reprogramming in Salmonella within macrophages
Salmonella expresses the arginine decarboxylase AdiA, which confers acid resistance by catalyzing an H+-consuming reaction. Researchers have discovered that the 3′-untranslated region (UTR) of adiA mRNA is processed by RNase E into a regulatory small RNA, AdiZ.

NewsDouble trouble: Tobacco use and Long COVID
Researchers investigating the relationship between Long Covid symptoms and smoking by tobacco type found that certain symptoms correlated with different forms of smoking.

NewsStudent focused on pathogens says new award has opened a door to span aquaculture and ecology
A University of Stirling student who is the latest recipient of the Nikos Steiropoulos Aquaculture Scholarship from MSD Animal Health UK says the award has helped to “open a door she could only have dreamed of”.

NewsStudy identifies blood protein albumin as key defense against deadly fungal infection ‘mucormycosis’
A new study has identified albumin as a powerful and previously unrecognized defense against a rare but often fatal fungal infection. Patients with mucormycosis had markedly lower levels of albumin compared with patients suffering from other fungal infections.

NewsMore investigations needed into Wumei Pills-Lactobacillus Reuteri-intestinal stem cell axis for chemotherapy-Induced mucositis
A new letter appraising a recent study suggests the reported benefits of WMP and Lactobacillus reuteri in chemotherapy-induced mucositis are promising, but stronger causal and analytical foundations are needed.

NewsSourdough starters reveal a recipe for predicting microbial species survival
Scientists used microbes in bread dough to test a simple way to understand how species live together in nature.

NewsBiologists and engineers follow goopy clues to plant-wilting bacteria
Slippery, drippy goop makes Ralstonia bacteria devastating killers of plants, causing rapid wilting in tomato, potato and a wide range of other crops, according to new research.

NewsAncient DNA pushes back record of treponemal disease-causing bacteria by 3,000 years
Scientists have recovered a genome of Treponema pallidum from 5,500-year-old human remains in Sabana de Bogotá, Colombia. The research expands knowledge about the history of this infectious disease and its occurrence in human populations.

NewsNew research suggests gut bacteria may be linked to memory decline in mild cognitive impairment and Alzheimer’s disease
A new review is shedding light on the growing evidence that gut microbiome imbalances—known as dysbiosis—may play a key role in the development and progression of mild cognitive impairment (MCI) and Alzheimer’s disease.

NewsScientists illuminate ancient plant-fungus partnership at molecular level
Researchers have coupled two powerful tools that allow scientists to identify which proteins work together to make plant-fungi partnerships function—and to verify those interactions in living plant roots, where the collaboration actually occurs.

NewsResurrected ancient enzyme offers new window into early Earth and the search for life beyond it
By resurrecting a 3.2-billion-year-old enzyme and studying it inside living microbes, researchers have created a new way to improve our understanding of the origins of life on Earth. The study uses synthetic biology to reverse-engineer modern enzymes and rebuild their possible ancestors.

NewsTwo days of oatmeal reduce cholesterol level - thanks to impact on gut microbes
A short-term oat-based diet appears to be surprisingly effective at reducing the cholesterol level. The diet apparently influenced the composition of microorganisms in the gut. The metabolic products, produced by the microbiome, appear to contribute significantly to the positive effects of oats.
