NewsFungal disease endangers wheat production as climate change bites
Researchers have shown that further spread of the fungal disease wheat blast could reduce global wheat production by 13% until 2050. The result is dramatic for global food security.

NewsResearchers document microbial wonders in earth’s saltiest waters
A new study explores the largely unknown metabolic capabilities of unclassified microbial species in extreme environments, particularly hypersaline lakes, and their potential applications in biotechnology, medicine, and environmental remediation.

NewsChemical signals spur soil bacteria to slam on the brakes
Scientists have lifted the lid on the miniature world of soil microbes, revealing how they sense and move in response to a variety of chemical and nutrient signals at various stages of symbiosis with legume plants.

NewsNew study reports that Greenland is a methane sink rather than a source
Researchers at the University of Copenhagen have concluded that the methane uptake in dry landscapes exceeds methane emissions from wet areas across the ice-free part of Greenland.

NewsSynthetic communities slash herbicide use for weed control
Synthetic microbial communities have been found to not only suppress the growth and yield of agricultural weeds, but also substantially strengthen infested wheat production.

NewsScientists probe ‘superpower’ that allows soil bacteria to protect rice roots from pollution
Scientists have lifted the lid on how changes in cell surface hydrophobicity of a strain of soil bacterium may help to stave off heavy metal-polycyclic aromatic hydrocarbon pollution from entering rice plant roots.

NewsTiny tornadoes around leaves spread deadly plant pathogens
A new study is the first to analyze plant spore dispersion at its source, where rain droplets shake flexible leaves to initially disperse pathogens.

NewsFungal-rich soil may improve green roofs
Active management of green roof mycorrhizal fungi accelerates soil development faster than if mycorrhizal fungal communities are left to passively reestablish on their own, a new study shows.

NewsNew purpose-built insectary will tackle spread of deadly diseases
Keele University is to create a new purpose-built insect research laboratory on its campus – where scientists will carry out vital research to tackle the spread of deadly diseases and reduce crop losses to pests.

NewsFluvo-aquic soil treated with pig manure present higher risk of AMR bacteria than black and red soils
A new study demonstrates that CTC-manure induced more resistance of soil indigenous microbes in fluvo-aquic soil. Manure control is an effective way to reduce the risk of soil AMR.

NewsGreen alternative for treating Streptococcus iniae bacteria in hybrid striped bass
Scientists at the United States Department of Agriculture (USDA)’s Agricultural Research Service (ARS) have developed a green antibiotic alternative to treat the deadly pathogen Streptococcus iniae in hybrid striped bass, the fourth most farmed finfish in the United States, according to a recent study.

NewsNitrogen-based fertilizers differentially affect protist community composition in paddy field soils
New research investigating the differential effects of nitrogen fertilizer types on paddy field protist communities showed that predatory protists were the major functional and most sensitive group to nitrogen fertilizers.

NewsRising sea levels could lead to more methane emitted from wetlands
A low-salinity Bay Area estuary ecosystem is producing higher-than-expected levels of methane.

NewsWest Nile virus emergence and spread in Europe linked to agricultural activities
The spread of West Nile virus in Europe is strongly linked to agricultural activities, urbanization, and bird migration, according to a modelling study.

NewsMicrobiome transplants from wild and lab-reared mosquitoes spur differing gene expression in recipient mosquitoes
Mosquitoes that receive microbiome transplants respond differently depending on whether the donor was wild or lab-reared, a new study has revealed.

NewsStudying defensive bacteria in squid and newts may help human gut health
Elizabeth Heath-Heckman has received a $1.9 million grant to support her research studying the bacteria animals like squid and newts use to protect themselves.

NewsExperiment shows how predator mass mortality events affect food webs
A team of biologists experimentally caused a predator die-off to understand how rapid predator deaths affect freshwater ecosystems.

NewsCooler conditions spur bacterial prey species to become the predator
In a new study, two species of bacteria grown in a lab reversed their predator-prey relationship after one species was grown at a lower temperature.

NewsResearchers reveal how archaea toggle the nitrogen-uptake switch
By tightly regulating nitrogen uptake, microorganisms avoid overeating nitrogen and thus wasting energy. Scientists now reveal how some methanogenic archaea manage to do so.
