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.

Could ‘Trojan horse’ microbes that exploit symbiotic systems be candidates for new biological pesticides?
Researchers have discovered a new insect pathogen that invades the gut symbiotic organ of stink bugs by mimicking their symbiotic microorganism, and this pathogen ultimately kills the host bugs.

Breakthrough study could unlock key to more reliable truffle cultivation
A pioneering study has revealed that growing truffles depends not just on soil conditions, but on a complex underground ecosystem that the truffles may help to engineer themselves.
NewsExtreme droughts in the rainforest reduce important feedback between soil and atmosphere
The El Niño drought and heat suppress the capacity of the Amazon rainforest soil to absorb isoprene by a factor of four, while boosting its amount around the forest canopy.
NewsA non-toxic guard against Lyme disease could soon be an everyday purchase
Rather than vaccinating people or pets against Lyme disease, researchers are targeting the “reservoir hosts” — small mammals like squirrels, chipmunks and white-footed mice — that naturally carry the bacterium and pass it to ticks.
NewsNew evolution platform creates tougher yeast for sustainable biomanufacturing
Researchers have now developed a powerful new tool that accelerates microbial evolution. Their study introduces RAMPAGE, a programmable system that continuously generates genetic diversity across the genome of the industrial yeast P. pastoris.
NewsTiny DNA ‘hitchhikers’ may be reshaping life in thawing Arctic soils
A new study in the peatlands of northern Sweden provides one of the clearest pictures yet of how frequently microbes swap, gain and lose genes in nature. The study establishes a new framework for measuring genetic mobility in natural environments.
NewsWidespread saprotrophs identified as the hidden engine of soil carbon decomposition
A nationwide study across China reveals that broad geographic distribution, rather than local diversity alone, determines which soil fungi actively fuel carbon decomposition and shape future carbon dynamics under climate change.
NewsTick-borne diseases reported every month of the year and in every Illinois county
A new analysis of state health department data reveals that more than 6,400 Illinois residents were diagnosed with tickborne diseases from 2004-2022.
NewsRice-crayfish farming strengthens soil nutrient cycling
Using metagenomic sequencing, a study has shown that integrated rice-crayfish systems increase the abundance of functional genes involved in methane oxidation, nitrogen degradation, denitrification, organic phosphorus mineralization, and phosphorus transport compared with rice monoculture.
NewsSoil moisture tips the balance of nitrogen cycling
A new study reveals that nitrite accumulation is not simply a chemical outcome, but the result of mismatched microbial activities between ammonia oxidizers and nitrite oxidizers.
NewsScientists deploy biofilm-targeting approach to improve crop disease resistance
A new study reports a biofilm-targeting approach for improving crop disease resistance. By replacing the native chloroplast transit peptide (CTP) of MOC1 with a secretory signal peptide (SP), the team redirected the enzyme from chloroplasts to the apoplast.
NewsStudy: China reverses widespread freshwater deoxygenation via wastewater management
Freshwater ecosystems worldwide have been suffering from declining oxygen levels that threatens biodiversity, fisheries, and ecosystem stability. However, a new study offers hope: targeted nutrient management via wastewater control can reverse this trajectory, even in the face of rapid climate warming.
