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.

NewsStudy 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.

Biochar 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.
NewsShiga-producing E. coli infections are becoming more resistant to antibiotics
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.
NewsProfessor Kaneko’s sake and wine earn honors at French Japanese Sake Competition for second consecutive year
At “Kura Master,” a Japanese sake competition held in France for French consumers since 2017, “Aldebaran,” a wine produced from grapes grown in the city of Ibara, in Okayama Prefecture, and supervised by Professor Akihiro Kaneko, won a Gold Award in the Muscat Bailey A category.
NewsThe right heat makes biochar a better helper for food waste composting
A new study finds that hardwood biochar made at 400 °C best protects nitrogen during food waste digestate composting, offering a practical route to cleaner and higher-quality compost.
NewsMagnetic biochar gel helps keep arsenic and antimony out of rice
A new study reports a promising strategy for mining-impacted regions: a magnetic silicon-enriched biochar gel that can immobilize both arsenic and antimony in contaminated paddy soil and reduce their accumulation in rice grains.
NewsHow Chinese cabbage fights downy mildew
Researchers focusing on the Brassica rapa–Hyaloperonospora parasitica pathosystem identifies DM459 as an Arg–x–Leu–Arg (RXLR) effector that interacts with BraATG8i, activates autophagy, stimulates salicylic acid (SA) signaling, and enhances resistance to downy mildew.
NewsBiochar could help make tea farming cleaner, safer, and more climate resilient
A new review examines how biochar, a carbon-rich material produced by heating biomass under limited oxygen, could become a practical tool for more sustainable tea cultivation. It focuses on five connected areas: soil properties, microbial communities, nutrient cycling, tea productivity and quality, and heavy metal detoxification.
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.
Long ReadsLosing the Earth’s bounty
Farmland degradation and soil erosion have caused food shortages and the collapse of civilizations throughout human history. Today, soil degradation is a growing driver of global threats such as climate change, biodiversity loss, and food insecurity. Loss of soil, the resource that supports production of 95% of the food supply, ...
NewsResearch shows plants such as canola, tomatoes and rice reduce iron uptake when stressed by drought
New research has found that plants, ranging from canola to rice to tomatoes, actively shut down their own ability to take up iron when they experience drought. The study questions whether plants send out a ‘cry for help’ when they are stressed by drought to recruit beneficial soil microbes in their roots.
