NewsThe invisible threat in air, water, and food: how ammonia quietly harms liver, brain, and gut
Ammonia is everywhere in modern life—released by farms, industry, and waste systems—and it reaches people through more routes than most realize. A review maps ammonia’s routes into the body, the liver-gut axis that keeps it in check, and engineered-bacteria transplants emerging as a possible therapy.

NewsEngineered plant–microbe symbiosis turns wastewater metals into photosynthetic biohybrids
A new plant–microbe strategy could change how wastewater heavy-metal pollutants are managed: instead of merely capturing toxic cadmium and lead, it converts them into light-harvesting semiconductor nanoparticles on living bacteria. The system pairs water lettuce with an engineered, fast-growing aerobic bacterium.

NewsHorizon Awards 2026: Professor James Ebdon named as winner of John Snow Prize
Environmental microbiologist Professor James Ebdon, from the University of Brighton, UK, has been named as the winner of the John Snow Public Health Innovation Prize, which recognises outstanding achievements in applied microbiology that deliver measurable improvements in public health and environmental health outcomes.

NewsResistant bacteria are favored in hospital sewers – responsible antibiotics identified
A study examined sewer systems and wastewater from hospitals and municipal treatment plants in eight Swedish cities. Sewage from all ten hospitals promoted antibiotic-resistant bacteria, while no such effects were found after exposure to sewage from the corresponding municipal treatment plants.

NewsMachine learning links water quality measurements to potential pathogen risks
A study of drinking water prediction systems shows that environmental measurements could support predictions of multiple microbial targets and generate potential health risk estimates broadly consistent with calculations based on measured pathogen concentrations.

NewsFungi that colonise human faeces: first scientific study lays the groundwork for myco-sanitation
Filamentous fungi can colonise fresh human faeces, and the choice of fungal species shapes how the material changes, according to a new study. Depending on the species, the fungi accelerated degradation, reduced faecal indicator bacteria, suppressed faecal odour or changed the appearance of the material.

NewsWater transformed into a weapon against antibiotic-resistant bacteria
Engineers have developed a new approach for turning ordinary water into a weapon against antibiotic-resistant bacteria, according to a study that hinges on a new kind of crystal made from titanium dioxide. These crystals transform the normal oxygen molecules in water into a special molecule known as “singlet” oxygen.

NewsWHO reports latest global trends in cholera, meningitis and plague
Cholera deaths increased by 30% in 2025, despite fewer cases being reported to the World Health Organization (WHO). In 2025, 47 countries reported 451 499 cholera cases and 7870 deaths to WHO, the highest number of annual cholera deaths reported to WHO since 1999.

NewsRainwater tanks may be harbouring hidden health risks
Rainwater tanks are a popular way for Australians to save water, but new research has found they can also harbour potentially harmful bacteria and metals that could pose health concerns.

NewsBacteria pulled from local pond water show early promise for cleaning up sewage
A new study identifies green sulphur bacteria from Peshawar pond samples that reduced pollution markers in wastewater after a week of treatment.

NewsWas Nîmes depopulated by the Plague of Cyprian?
Analyses of the carbonate deposits in the aqueduct featuring the famous Pont du Gard shed light on the water supply of the ancient city of Nîmes - and support the theory that the city was depopulated by the plague.

NewsIntermediate nitrification/denitrification bioreactor closes a gap
Researchers present a method for nitrification and denitrification of septic effluent comprising an intermediate nitrification/denitrification bioreactor which builds on concepts currently used in the design of full‑scale wastewater treatment plants.

NewsCo-digestion of waste and wastewater from biomanufacturing for energy recovery
Researchers have developed the Anaerobic Baffled Continuous Stirring (ABCS) reactor, a device capable of simultaneously treating solid waste and wastewater from biomanufacturing processes while recovering methane for energy self-sufficiency.

NewsRiver drinking water sources may face greater antibiotic resistance risks than reservoirs, study finds
A basin-wide study of 13 drinking water sources in China’s Poyang Lake region shows that water source type can strongly shape the occurrence and spread of antibiotics, antibiotic resistance genes, and resistant bacteria.

NewsPreliminary wastewater bioremediation by photosynthetic Chlorobium genus isolated from pond water
Researchers have isolated naturally occurring light-driven bacteria from local pond water and shown that, within just one week, these microorganisms can substantially reduce the levels of organic pollutants in raw sewage.

NewsReview explores the presence, fate, and effects of pharmaceutical compounds in soil and air
Pharmaceutical contamination in soil and air has become a critical environmental concern due to its widespread sources, complex behavior, and long-lasting ecological impacts.

NewsWastewater may offer an early warning of pertussis outbreaks
Researchers found that pertussis-associated DNA in wastewater rose weeks before reported whooping cough cases, pointing to a new way to complement clinical surveillance.

NewsHospital wastewater controls help contain antibiotic resistance in nearby waters
A new study of hospital wastewater reports that geography, rather than hospital proximity, primarily shaped resistance-gene profiles where wastewater controls were well established.

NewsMultidisciplinary framework bridges earth science and environmental engineering to combat waterborne pathogens
Waterborne pathogens remain a leading cause of infectious disease globally, responsible for 24% of all deaths and over 10 million fatalities each year. Source: Zheng-Yang Huo, et al. Graphic Abstract Despite decades of progress in water treatment, conventional approaches have struggled to keep pace with the evolving ...
