NewsFifteen-year cattle manure application reshapes phoD- and gcd-harboring microbiomes, enhancing vegetable yields
A new study demonstrates that combined manure and chemical fertilizer (M+CF) in an open-field lettuce cropping system enhanced both diversity (+45.3%) and abundance (+290%) of gcd-harboring bacteria.

NewsMicroalgal–Bacterial granules show resilience to estrogen pollution but face structural collapse at high contamination levels
A study reveals both the adaptive biodegradation potential and the vulnerability of MBGS under estrogenic stress, offering new insights for developing robust, biologically based wastewater treatment technologies.

NewsEnvironmental traces of antibiotics found to boost gene transfer among bacteria
Using models of vertical inheritance and horizontal transfer, researchers have found that low doses of tetracycline, ampicillin, kanamycin, and streptomycin stabilize resistance and promote gene transfer across species.

NewsMicrobiome of an entire country is mapped for the first time
An international research team has systematically mapped the microbiome of an entire country for the first time. More than 10,000 environmental samples from across Denmark were analyzed, resulting in an atlas of environmental microbiomes with unprecedented spatial resolution and functional depth.

NewsIsland-wide field surveys illuminate land-sea connections in Mo‘orea
A multi-year scientific expedition determined that land use on tropical islands can shape water quality in lagoons and rainfall can be an important mediator for connections between land and lagoon waters.

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’.

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.

NewsCAROSEL offers new ‘spin’ on monitoring water quality in real time - and tracking harmful algal blooms
Researchers can continuously track the exchanges of different forms of nitrogen between bottom sediments and the overlying water. Their novel approach enables measuring how much ammonium (NH₄⁺) is released from sediments in real time, multiple times a day, over an extended period.

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.

NewsClimate change may increase the spread of neurotoxin in the oceans
Climate-driven oxygen loss in the Black Sea thousands of years ago triggered the expansion of microorganisms capable of producing the potent neurotoxin methylmercury. That is shown in a new study which suggests that similar processes could occur in today’s warming oceans.

NewsNew biochar technology promises breakthrough in soil clean-up and crop safety
Scientists have unveiled a pioneering method that could help farmers reclaim lands blighted by toxic metals and boost the safety of crops grown in contaminated soils. Phosphorus-modified biochar can reduce the threat posed by heavy metals in agricultural soils near mining areas.

NewsMicrobial DNA sequencing reveals nutrient pollution and climate change reinforce lake eutrophication
A new study using DNA sequencing of lakebed microbes reveals that nutrient pollution from agricultural runoff and climate change amplify each other in ways that profoundly affect the health of lake ecosystems.

NewsRivers’ hidden helpers: microbes that clean up nitrogen pollution across China
A new study has revealed how tiny microbes in rivers and wetlands across China help clean up excess nitrogen pollution, offering fresh insights into the health of freshwater ecosystems and the global nitrogen cycle.

NewsScientists show how to grow more nutritious rice that uses less fertilizer
Scientists have shown that nanoscale applications of selenium can decrease the amount of fertilizer necessary for rice cultivation while sustaining yields, boosting nutrition, enhancing the soil’s microbial diversity and cutting greenhouse gas emissions.

NewsImperfect underground processes help filter wastewater in Florida Keys
Researchers find that microbial and other processes do not completely clear wastewater shallowly injected into groundwater of potentially harmful contaminants.

NewsSimple rules govern soil microbiome responses to environmental change
New research shows that a deceptively simple mathematical model can describe how the soil responds to environmental change. Using just two variables, the model shows that changes in pH levels consistently result in three distinct metabolic states of the community.

NewsNitrogen may limit natural climate solutions
A global inventory reveals nitrogen is in shorter supply than previously thought in natural areas, which could limit carbon storage in plants and soils.

NewsResearchers to harness the power of fungi for water filters
A groundbreaking project exploring the power of fungi to combat agricultural pollution is making significant strides, with researchers looking to begin live field trials later this year.

NewsClimate change is turning coastal lagoons into ‘salty soup’
The impacts of human activity and climate change are coalescing to make coastal lagoons saltier, changing the microbial life they support and the function they play in their ecosystems, according to new research.

NewsScientists link a phytoplankton bloom to starving dolphins in Florida
In 2013, 8% of the bottlenose dolphins living in Florida’s Indian River Lagoon died. Investigations have now revealed that the dolphins may have starved because key habitats for nutritious prey were destroyed by a phytoplankton bloom driven by the accumulation of fertilizer, effluent from septic tanks, and other by-products of human activity.
