NewsDrinking water people believe to be safe and clean often contain potentially dangerous bacteria
A study in Guatemala found the sources of drinking water people believe to be safe and clean often contain potentially dangerous bacteria. Bottled water sold in large refillable jugs was the most frequently contaminated with coliform bacteria – an indicator of fecal contamination.

NewsNew nanogel technology destroys drug-resistant bacteria in hours
A novel technology shows over 99.9% effectiveness against Pseudomonas aeruginosa (P. aeruginosa). It centres on a heteromultivalent nanogel: a flexible particle made by crosslinking polymers and adding sugar residues (galactose and fucose) alongside antimicrobial peptides.

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.

NewsFlower to fruit: tracking the changing fungal community on blueberry plants
A study identifies how fungal diversity changes over time and across tissue types in highbush blueberry, revealing dynamic transitions in the phyllosphere from buds to ripe fruits. Early-season buds and flowers harbor the highest fungal diversity, while unripe green fruits display the lowest.

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 ...
