NewsThe climate crisis threatens river microbial biodiversity
A study warns that the biodiversity and biological functions of aquatic fungi in rivers are at risk due to rising temperatures, prolonged dry periods and the loss of riparian vegetation caused by climate change.

NewsUnsafe water still drives global diarrheal disease burden
A new study, analysing data from the Global Burden of Disease 2021 database, found that deaths and disability-adjusted life years linked to unsafe water have declined sharply over the last three decades. Nevertheless, the burden remains concentrated in low socio-demographic index regions.

NewsHow cyanobacteria developed photosynthetic membranes over the course of evolution
New research analyses hundreds of cyanobacterial genomes to understand the origin of thylakoids, the internal membranes involved in photosynthesis.

NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.

NewsHow sea-ice microbes survive the Southern Ocean’s harsh winter, and the implications for climate change
New study reinforces the importance of the Southern Ocean marginal ice zone as a critical hotspot for global sulfur cycling where biogeochemical processes for climate regulation are enhanced.

NewsEffects of polystyrene nanoplastics and organophosphorus flame retardants on salamander gut-liver axis
New research reveals the effects of polystyrene nanoplastic and the organophosphorus flame retardant exposure on the gut-liver axis of salamanders.

NewsExploring potential of virovory in combating harmful algal blooms
Toxic cyanobacterial blooms can close lakes, contaminate drinking water and pose risks to human health. A new project is exploring an unlikely tool for mitigating these blooms: virovory, the phenomenon of organisms eating viruses as a food source.

NewsStarvation triggers reversible epigenetic changes in fish pathogen
What happens to a bacterial pathogen when food runs out—for several months? A new study reveals that Flavobacterium columnare, a deadly aquatic pathogen responsible for columnaris disease in fish, does not change its DNA sequence during prolonged starvation. Instead, it remodels its epigenetic landscape.

NewsInternational award honors microbiology researchers for diatom research
Two microbiology researchers from the University of Tennessee, Knoxville, are being honored with an international award that recognizes their insights into aquatic microbes that are vital to Earth’s ecosystems.

NewsNewly discovered microbial world helps protect developing lobsters
As ocean temperatures rise and marine ecosystems change, scientists are working to understand how valuable species like the American lobster will respond. Scientists suggest one source of resilience may come from the microscopic bacterial communities living on lobster embryos.

NewsHidden viruses reshape one of Earth’s largest carbon systems, study finds
Viruses play a far more active role in Earth’s carbon cycle than previously understood, according to new research that reveals how they infect and control microbes responsible for carbon production in some of the planet’s largest, darkest ecosystems.

NewsStudy provides detailed assessment of shifts in toxin producing phytoplankton abundance
Researchers in the UK have shown how the distributions of two phytoplankton groups – known to produce natural toxins that can halt shellfish harvesting – have changed in the North East Atlantic over the last six decades.

NewsStudy finds warmer streams may weaken river food webs
Rising stream temperatures may be weakening the foundation of river food webs by altering how carbon moves through these watery ecosystems. When water temperatures increase, microbes and aquatic insects process fallen leaves, twigs and bark more rapidly, but a smaller fraction of that leaf litter supports their growth.

NewsHow soil microbes adapt to life in lakes
Researchers have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits – but others reduce the size of their genome and lose some functions in order to successfully move to a new home.

NewsFunctional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.

NewsTiny plankton have big impact on harmful algal bloom predictions
While some computer models can forecast potential algal blooms, their accuracy is limited.. A new study shows that coupling three models and accounting for how different algae species interact can significantly improve predictions.

NewsStopping algae blooms with bacteria-busting buoys
Algae blooms make a pond’s surface shine in mesmerizing green hues. But if the microorganisms responsible are cyanobacteria, they can also release toxins that harm humans and wildlife alike. So, a team reporting in ACS ES&T Water has designed a “set it and forget it” system for distributing algaecide using ...

NewsTiny plastics, green solutions: How algae could help clean polluted waters
A new review examines how algae interact with microplastics in aquatic systems. Importantly, it highlights how their biological interactions could be harnessed to mitigate microplastic pollution, offering new perspectives for sustainable aquatic environmental management.

NewsDiisobutyl phthalate at environmental concentration promotes conjugative transfer of antibiotic resistance genes
Researchers investigating the ecological safety risks posed by dibutyl phthalate (DBP), in aquatic environments found it significantly increased conjugative transfer frequency in both intragenus (E. coli DH5α to E. coli HB101) and intergenus (E. coli DH5α to B. subtilis WB100N) systems.

News10 Years, 70% shift: Wastewater upgrades quietly transform river microbiomes
Researchers investigated how the upgrade of a WWTP influenced nitrogen-cycling microorganisms and DNA viruses in its receiving river. The research compared the river whose WWTP was upgraded during the study period against the river whose upgrade occurred prior to the study.
