NewsNew collection of bacteria-eating viruses can tackle hospital superbug
An international team of researchers have comprehensively catalogued a new collection of bacteria-eating viruses called phages sourced, in part, from hospital wastewater. The phages have been shown to be effective against different strains of Klebsiella pneumoniae.

NewsGlobal Virus Network awards pandemic preparedness grants to advance global surveillance and early detection of viral threats
The Global Virus Network (GVN) is awarding pandemic preparedness research grants, totaling $160,000, to scientists across four continents, supporting innovative, investigator-led projects designed to enhance viral surveillance, early detection, and scientific preparedness.

NewsNew study finds higher levels of antimicrobial resistance (AMR) in surface water during winter
A new study has found that the levels of antimicrobial resistance (AMR) present in surface water increase during winter. Flooding, sewer overflows and agricultural run-off all contribute to a cocktail of pollutants that can increase AMR genes in surface water, potentially turning regular bugs into ‘superbugs’.

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.

NewsSmart toilet designs in Cambodia held promise, but a key piece was missing
A smart toilet design introduced in rural Cambodia was supposed to change lives—keeping families safe and protecting the environment. However, while households reported that they liked the new system, a crucial piece was missing: using it correctly.

NewsEmerging pollutants threaten efficiency of wastewater treatment: New review highlights urgent research needs
A new scientific review has shed light on how emerging pollutants commonly found in wastewater are disrupting biological phosphorus removal processes, posing risks to water quality and ecological health. The study examines how pharmaceuticals, microplastics, and industrial chemicals interfere with the key microorganisms responsible for phosphorus removal in wastewater treatment plants.

NewsEveryday levels of antibiotics in the environment may accelerate the global spread of resistance, new study finds
A new study shows that even very small amounts of antibiotics that commonly appear in soil, rivers, wastewater, and agricultural runoff may significantly accelerate the spread of antibiotic resistance genes among bacteria.

NewsMystery toxic algae regime change in Salem’s drinking water source
A long-term analysis shows that a major Oregon reservoir abruptly swapped one type of toxic algae for another midway through the 12-year study period, absent any obvious cause.

NewsMicroalgal-bacterial sludge offers sustainable solution for removing hormonal pollutants from wastewater
A team of researchers have revealed how microalgal-bacterial granular sludge (MBGS) can adapt and efficiently degrade estriol, a common endocrine-disrupting compound (EDC), under environmentally relevant conditions.

NewsResearchers screen microbial strains to reduce H2S and CH4 emissions from wastewater
A new study demonstrates that S. cerevisiae and B. subtilis effectively reduce H2S and CH4 emissions from wastewater by altering microbial community composition and metabolic pathways, offering a sustainable approach for wastewater treatment.

NewsBiochar mediated microbial synergy in partial nitrification–anammox systems
A study investigates the role of biochar in enhancing nitrogen removal efficiency (NRE) and stability in partial nitrification–anammox (PN/A) systems, focusing on its selective promotion of partial denitrification and maintaining the dynamic balance between AnAOB and denitrifying bacteria (DNB).

NewsDrones reveal unexpectedly high emissions from wastewater treatment plants
Greenhouse gas emissions from many wastewater treatment plants may be more than twice as large as previously thought. This is shown in a new study in which the researchers used drones with specially manufactured sensors to measure methane and nitrous oxide emissions.

NewsGlobal study reveals how bacteria shape the health of lakes and reservoirs
A sweeping new study has uncovered global patterns in how bacteria thrive and interact within lakes and reservoirs, offering new insights into the invisible forces that sustain freshwater ecosystems.

NewsScientists to probe how microbes break down water-soluble polymers in wastewater
Scientists and industry have teamed up to investigate how microbes in wastewater interact with and potentially biodegrade polymers called viscosifiers.

NewsStudy shows differences between documented and self-reported polio vaccination rates
Until poliovirus is eradicated worldwide, vaccination protection is important as the virus could be reintroduced at any time. Epidemiologists have now shown that many people in Germany do not know their vaccination status and cannot find it on their vaccination record.

NewsGlobal analysis reveals how biochar supercharges composting and cuts greenhouse gases
By analyzing data from 125 studies across the world, researchers showed that adding biochar to composting systems significantly boosts compost quality while slashing harmful greenhouse gas emissions.

NewsAlgae and water fleas in lakes: Light color influences food webs
Phytoplankton are the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.

NewsWetland plant-fungus combo cleans up ‘forever chemicals’ in a pilot study
From a greenhouse study, researchers report that moisture-loving yellow flag irises and fungi on their roots are a promising combination for PFAS removal. As part of a constructed wetland, this pair could effectively treat contaminated wastewater.

News‘Cocktails’ of common pharmaceuticals in our waterways may promote antibiotic resistance
New research has shown, for the first time, how mixtures of commonly used medications which end up in our waterways and natural environments might increase the development of antibiotic resistant bacteria.

NewsValorization of soybean-processing wastewater sludge via black soldier fly larvae: performance and bacterial community dynamics
A new study indicates that the valorization of soybean-processing-sourced sludge via black soldier fly larvae was achieved via functionally important BSFL intestinal microbiota, providing an efficient recycling approach for similar waste streams.
