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.

NewsSurgeon-scientist studying sinus microbiome in chronic rhinosinusitis patients
A surgeon-scientist is leading a multi-institutional grant investigating the role of the sinus microbiome in chronic rhinosinusitis, an inflammatory disease that causes the lining of the sinuses to swell.
-
NewsResistant bacteria can remain in the body for years
People with pre-existing conditions in particular can carry resistant germs and suffer from repeated infections for years, according to a new study.
-
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.
-
NewsScientists shine a new light on the tug-of-war between virus and host
Researchers have recently developed a new method that, for the first time, enables the discovery of interactions for specific regions within a target RNA molecule.
-
NewsResearchers expose the core of poxviruses
A team of researchers has uncovered the mysteries of poxviral core architecture by combining various cryo-electron microscopy techniques with molecular modeling.
-
NewsScientists spot an ultra-fast movement on surface of HIV virus
Investigators catch ultra-fast HIV docking mechanism in the act, giving them a new handle on the surface of the virus that could lead to broadly neutralizing antibodies for an AIDS vaccine.
-
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.
-
NewsArrangement of bacteria in biofilms affects their sensitivity to antibiotics
New research shows that bacteria that form biofilms actually have a highly structured arrangement within those slimy matrices.
-
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.
-
NewsNew and highly infectious E. coli strain resistant to powerful antibiotics
A more infectious version of the bacterium is found to have caused two outbreaks in a children’s hospital in China.
-
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.
-
NewsResearchers detect hepatitis viruses in wastewater
High-throughput sequencing of river water samples showed that it is possible to identify different genetic variants of the hepatitis E virus in wastewater.
-
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.
-
NewsModified phage DNA can kill deadly pathogens
DNA modified from a bacteriophage and put inside Pseudomonas aeruginosa was found to bypass the pathogen’s defense mechanisms to assemble into virions, which sliced through the bacterium’s cell to kill it.
-
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.
-
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.
-
NewsInfection ability of viruses reduced by 96% using mechanical methods
An international research project in which the URV has taken part has designed and manufactured a surface that has virucidal properties but does not use any chemicals.

NewsSwitching to vegan or ketogenic diet rapidly impacts immune system - and gut microbiome
A study found that switching to a vegan diet prompted responses linked to innate immunity, while the keto diet elicited responses associated with adaptive immunity, along with metabolic changes and shifts in the gut microbiomes.
