NewsBiodegradable mulch isn’t disappearing as expected, new study warns
Scientists investigated how soybean roots influence the degradation of PBAT microplastics in soil. They tracked both polymer loss and monomer accumulation over a full 70-day plant growth cycle, revealing size-dependent and condition-specific rhizosphere effects.

NewsEditing for timing, not overdrive: A new genetic route to fire blight resistance in apple
Fire blight remains one of the most destructive bacterial diseases threatening global apple production. A new study identifies a family of inducible lectin genes, MdAGGs, as critical components of apple immune defense and demonstrates that their precise activation timing is key to effective resistance.

NewsA common CRISPR platform enables comparative studies of multicellularity in social amoebae
Researchers have established a CRISPR genome editing technique that enables comparative analysis of the evolution of multicellularity across different species of social amoebas (cellular slime molds). Until now, genetic studies had been largely restricted to a single model species.

NewsAncient symbiosis between plants and fungi: Important insights for sustainable agriculture
Almost all plants live in close symbiosis with so-called mycorrhizal fungi – an important symbiosis for absorbing essential nutrients. Scientists have discovered that this mycorrhizal symbiosis is very sensitive to imbalances of certain nutrients in the soil.

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.

NewsToxic algal bloom takes heavy toll on mental health
The year-long algal bloom along the South Australian coastline has not only devastated marine life and triggered health risks for humans and pets: it has also had a significant psychological impact on local residents, according to new research.

NewsBig and small dogs both impact indoor air quality - just differently
An initial study reports that dogs — both big and small — impact indoor air quality. The researchers found that small active dogs produced more airborne particles, but larger animals released more microbes into the air than people did.

NewsLife forms can planet hop on asteroid debris – and survive
The extremophile bacterium Deinococcus radiodurans can survive the pressures developed during ejection from Mars as a result of massive asteroid impact, a study shows. It means microorganisms can survive more extreme conditions than previously thought, including launch across space after major impacts.

NewsTestosterone increases severity of bacterial skin infections
Men are more susceptible than women to skin infections caused by Staphylococcus aureus bacteria, but the biological basis for this disparity has remained unclear. A new study is the first to reveal testosterone, present at higher levels in males, as a key driver of infection.

NewsHuge toll: Bird flu rampant among black vultures
More than four out of every five dead black vultures examined by University of Georgia researchers tested positive for highly pathogenic avian influenza, according to a new study. Their indiscriminate scavenging appears to sustain transmission of the virus beyond the typical bird flu season.

NewsFecal transplants from older mice significantly improve ovarian function and fertility in younger mice
A new study details how fecal transplants from older female mice significantly improve ovarian function and fertility in young mice. The surprising results reveal a direct link between the microbiome of the gut and ovarian health and function.

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.

NewsScientists identify therapeutic target that would curb the spread of coronaviruses
Coronaviruses not only use the machinery of the human cells they infect: they modify it to achieve optimal conditions to produce viral proteins and thus spread more quickly, according to a study identifying enzymes that modify transfer RNAs as key elements for coronavirus infection.

NewsAlgal blooms: New AI algorithm enables scientific monitoring of ‘blue tears’
‘Blue tears’ chasing has become a popular tourism activity along coasts to witness the spectacular natural phenomenon. However, the occurrence and movement of algal blooms are unpredictable - but scientists have developed an innovative real-time video monitoring algorithm named BT-YOLO.

NewsPeriphyton closes the nitrogen budget gap in rice paddies
Scientists identify a previously overlooked microbial N sink in rice paddies. Periphyton, a thin microbial community that develops at the soil–water interface, is composed of algae, bacteria, and extracellular polymeric substances, forming a dense microhabitat with strong capacities for nutrient uptake, transformation, and temporary storage.

NewsNew study demonstrates universal newborn cCMV screening leads to earlier detection and increased identification of mild hearing loss
A new retrospective cohort study examining the impact of Minnesota’s first-in-the-nation mandated universal newborn screening for congenital cytomegalovirus (cCMV) shows that universal screening significantly decreased the age at first audiology visit and increased identification of mild hearing loss in infants.

NewsEpigenetic rewiring fuels potato susceptibility to late blight
Scientists performed whole-genome bisulfite sequencing and RNA sequencing on the widely cultivated potato cultivar Qingshu No.9 following Phytophthora infestans infection, uncovering dynamic DNA methylation shifts that correlate with large-scale transcriptional reprogramming and immune suppression.

NewsAkkermansia muciniphila PROBIO therapy promotes arginine biosynthesis and reverses reproductive impairments in polycystic ovary syndrome rats
A research study investigated the therapeutic potential of Akkermansia muciniphila PROBIO (AP) in a dehydroepiandrosterone-induced PCOS rat model, revealing significant improvements in reproductive and metabolic parameters through modulation of gut microbiota and enhancement of arginine biosynthesis.

NewsEnhanced inner ear tropism of Adeno-Associated Virus (AAV) vectors via peptide display on AAV1 capsid
Researchers improving efficiacy of AAV)-mediated gene therapy for the inner ear screened and inserted short peptide motifs onto the surface of the AAV1 capsid. These engineered vectors achieved markedly higher transduction rates in inner ear hair cells and supporting cells.
