NewsNew study reveals how a common antibiotic disrupts nitrogen cycling and boosts greenhouse gas emissions in estuaries
Antibiotics may have far reaching impacts on wetland chemistry, according to a new study that identifies the bacteria responsible for breaking down the antibiotic sulfamethoxazole and links this process to increased emissions of nitrous oxide, a potent greenhouse gas.

NewsCircadian rhythms as a modulator of gut microbiota-tumor microenvironment crosstalk
A new review examines how circadian disruption modifies the diversity and metabolic functions of gut microbiota, resulting in alterations of microbial metabolites, including short-chain fatty acids and secondary bile acids.

NewsEmerging human and canine leptospirosis in New South Wales shows separate transmission pathways
A geospatial study of leptospirosis outbreaks in New South Wales suggests that humans and dogs may have largely independent transmission pathways.

NewsScientists reveal molecular cause behind “stuck” beer fermentation
Premature yeast flocculation (PYF) is a persistent issue in beer brewing, where yeast settles too early during fermentation. New research identifies multiple differential metabolites and confirmed galangin as a key factor that promotes early yeast aggregation.

NewsScientists develop world’s first modular co-culture platform for the one-pot production of rainbow-colored bacterial cellulose
The team engineered Komagataeibacter xylinus for bacterial cellulose synthesis and Escherichia coli for natural colorant overproduction. A co-culture of these engineered strains enabled the in situ coloration of bacterial cellulose.

NewsLivestock manure linked to the rapid spread of hidden antibiotic resistance threats in farmland soils
Scientists have uncovered how even “low-risk” organic fertilizers like dried poultry manure can inadvertently drive a dramatic surge in dangerous antibiotic resistance genes, once released into vegetable plots used for food crops.

NewsImpact of pasteurization on dairy calves’ gut microbiota: A study of milk feeding and early microbial colonization
A new study highlights the impact of pasteurization on microbial diversity in dairy calves, underlining the importance of balancing pathogen safety and microbial health. It suggests that while pasteurization prevents pathogen transmission, it also reduces beneficial microbial transfer.

NewsGenetically engineered fungi are protein packed, sustainable, and taste similar to meat
Researchers used CRISPR to increase a fungus’s production efficiency and cut its production-related environmental impact by as much as 61%—all without adding any foreign DNA. The genetically tweaked fungus tastes like meat and is easier to digest than its naturally occurring counterpart.

NewsBacteria ‘pills’ could detect gut diseases — without the endoscope
Researchers report that they’ve developed a sensor made of tiny microspheres packed with blood-sensing bacteria that detect markers of gastrointestinal disease. Taken orally, the miniature “pills” also contain magnetic particles that make them easy to collect from stool. Excreted from mouse models with colitis, the bacterial sensor detected gastrointestinal bleeding within minutes.

NewsBiochar boosts clean energy output from food waste in novel two-stage digestion system
A new study from researchers at the University of Western Australia and Universitas Brawijaya has found that adding biochar to advanced food waste recycling systems can significantly increase the clean energy yields of hydrogen and methane. This breakthrough offers promising strategies for municipalities and industries aiming to turn food scraps ...

NewsGreen chemistry for sustainable personal care
A recent review examined microbial biosurfactants as sustainable alternatives to synthetic surfactants in shampoo formulations. The authors addressed the growing demand for environmentally friendly and dermatologically safe cleansing agents, and emphasized the need to transition from petrochemical-based ingredients such as sodium lauryl sulfate (SLS) to biodegradable biosurfactants.
