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.

New AI model improves accuracy of food contamination detection
Researchers have significantly enhanced an artificial intelligence tool used to rapidly detect bacterial contamination in food by eliminating misclassifications of food debris that looks like bacteria. Current methods often require specialized expertise and are time consuming — taking several days to a week.
NewsTexas-grown cabbage meets global tradition in kimchi research
Researchers are turning Texan produce into kimchi as part of a study that links fermentation science, food safety and new market opportunities for U.S. farmers. The research examines how Texas-grown cabbage and other leafy greens perform during kimchi fermentation.
FeaturesFrom roots to riches: mycorrhizal fungi and the future of farming
Feeding a growing population while rebuilding depleted soils is one of agriculture’s biggest challenges. When fungal networks are thriving, they can improve nutrient uptake, support stronger root systems, and reduce the need for fuels to stretch as far, with their input. It’s a small-scale partnership with big implications for the future of farming…
