Food security
Millions of people are undernourished globally and with the population growing, food security is a major concern. Food security is multifaceted, requiring advancements in food safety, ensuring products have a good shelf life, reducing spoilage and providing dietary additions to improve the nutrient intake of the population. The application of microbiology is far reaching, and new approaches are required to maintain food security. Through an improved understanding of plant-microbe interactions, it is possible to forecast and mitigate food shortages.

NewsJust 10 viral particles can cause H5N1 avian flu infection in cows
Just 10 viral particles of the H5N1 bird flu that caused hundreds of influenza outbreaks in U.S. dairy cattle can cause infection in cows, a new study shows. The research also hints at why the outbreaks have confounded scientists, farmers and livestock handlers hoping to contain and prevent the disease.
NewsPlant viruses open new routes for gene editing
A new study has developed potyvirus-derived vectors for delivering CRISPR RNA (crRNA) guides in Lachnospiraceae bacterium ND2006 Cas12a (LbCas12a)-expressing plants, expanding virus-induced gene editing from tobacco rattle virus (TRV) to tobacco etch virus (TEV), turnip mosaic virus (TuMV), and lettuce mosaic virus (LMV).
NewsFermentation science may offer new route to better lower-alcohol wine
In addition to finding ways to ferment grape juice without producing as much alcohol, one scientist is exploring novel yeasts and methods to overproduce aromas to compensate for their eventual loss when reducing alcohol through grape juice dilution.

Study reveals 45 new toxins produced by bacteria associated with foodborne infections
Researchers have discovered 45 new toxins produced by Salmonella bacteria, some of which are associated with foodborne infections. The study shows that these substances primarily act in the competition among microorganisms for space and resources.
NewsDegradable sensors reveal hidden soil secrets
New degradable sensors being developed by soil scientists track biological activity in soil by having a degradable substrate that is nibbled on by microbes.
NewsSlow down, microbes: When wheat learns to protect the nitrogen
Wheat plants can do more than grow grain. Research shows that their roots release natural compounds that slow down soil microbes and keep nitrogen in the soil potentially cutting losses, greenhouse gas emissions and costs for farmers.
NewsBiochar triggers a five-year soil recovery cascade in acidifying rice paddies
A long-term field study reveals how biochar reshapes soil chemistry, microbes, viruses, and metabolites to support healthier agricultural ecosystems.
NewsTwo types of biochar help alfalfa survive salty soils
A new study shows that carefully designed biochar can guide plant metabolism and reshape beneficial microbial communities around the roots to help reduce stress from saline-alkali soil.
NewsBiochar and beneficial microbes team up to restore polluted soils and boost crop growth
A new review examines how biochar-immobilized microbes can help clean contaminated soils, improve soil health, and support crop growth. By analyzing evidence from 92 published studies, the authors provide a data-driven overview of how this technology works and what is needed to bring it closer to practical use on farms.
NewsWarming may weaken biochar’s climate benefits in cropland soils, global study finds
Researchers found that warming significantly increased carbon dioxide emissions from soils treated with biochar by an average of 77%. The effect was especially strong in croplands, where emissions increased by 117.5%, compared with 30.9% in forest soils.

A new study indicates resistance to antimicrobial agents is rising among human infections with Shiga toxin–producing Escherichia coli bacteria.
NewsEurope’s crops under threat: €6 million project launches to tackle rising plant pest crisis
The University of Warwick leads a European consortium to build the first platform capable of coordinating Europe’s response to devastating agricultural and forest pest invasions. The project will give plant health authorities the ability to model and optimise pest control strategies across the entire agri-value chain.
NewsFood insecurity linked to gut microbiome changes in children
A new study shows that food insecurity may leave a measurable impact on the gut microbiome of children. Children in food-insecure households had different gut microbiome profiles, including higher levels of Sutterella, which has been linked to poor dietary quality and intestinal inflammation.
NewsIndigenous mushroom transforms agricultural waste into food
An edible, seasonal mushroom in Eastern Nigeria has nutritional and therapeutic potential but is poorly researched. New research suggests that domestication of Lentinus squarrosulus using waste materials, specifically sawdust, could boost food production and provide employment opportunities for farmers and small businesses.
