Healthy land
Land has a wide variety of uses: agricultural, residential, industrial, and recreational. Microbes play a key role in the terrestrial ecosystem, providing symbiotic relationships with plants. Human use of land has led to the exhaustion of nutrients in soils, contamination of land, and a reduction in biodiversity. Applying our knowledge of microbes will be essential in restoring the biodiversity of affected ecosystems. Greater research into how microbes impact human life on land could all have a positive impact, by increasing crop production, repurposing areas of land and improving microbial biodiversity in soil, land, and water.

How soil microbes adapt to life in lakes
Researchers have analyzed the genome of bacteria living in Lake Zurich to conclude that microbes employ two different strategies to colonize new habitats. Some acquire new traits – but others reduce the size of their genome and lose some functions in order to successfully move to a new home.

News‘Safe’ fertilizer linked to extreme water quality loss in Canadian Prairies
Research has found that widespread application of the common farm fertilizer, urea, severely degrades water quality in the Canadian Prairies. Urea added to farm ponds increased growth of algae to levels 10 times higher than seen in other damaged ecosystems, such as Lake Winnipeg in Manitoba.
NewsIn developing immunity to allergens, a little ‘dirty’ goes a long way
Exposure to diverse microbes and proteins early in life creates broad immune memory and a specific antibody that helps block allergic reactions later in life. Rather than overreacting to harmless allergens, an experienced immune system responds in a balanced way.
NewsMolecular biologist Li-Jun Ma wins 2026 Mahoney Life Sciences Prize
Li-Jun Ma has been chosen as this year’s winner of the Mahoney Life Sciences Prize for her work toward mitigating the effects of a fungal pathogen that is causing the functional extinction of the bananas most commonly found in U.S. supermarkets.

Functional traits, not phylogeny, drive gut microbial assembly in estuarine fish
By examining the gut microbiota of 61 sympatric fish species within the ecologically diverse Pearl River Estuary, researchers utilized this “natural laboratory” to disentangle complex biological drivers without the interference of geographical variation.
NewsStudy reveals hidden damage in stony corals using 3D imaging and AI
Researchers investigating how disease affects coral structure turned to X-ray microcomputed tomography which generates detailed 3D reconstructions down to microscopic pores, which reveal internal skeletal features, including porosity, thickness and structural orientation, in a non-destructive way.
