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.

Plastic bottles transformed into Parkinson’s drug using bacteria
A drug to treat Parkinson’s disease can be made from waste plastic bottles using a pioneering method. The approach harnesses the power of bacteria to transform post-consumer plastic into L-DOPA, a frontline medication for the neurological disorder.

NewsShell game: How oysters enlist help from microbes
Researchers have discovered that oyster microbes might help with the “heavy lifting” of calcification that forms oyster shells. These microbes and the oysters co-express – or coordinate – the expression of certain genes that hint at a chemical “dialogue” between the host and these microbes.
NewsMicrobial clues uncover how wild songbirds respond to stress
A study of free-living Northern cardinals revealed that even relatively mild challenges can leave a clear mark on the gut microbiome. Birds exposed to social or environmental stressors showed changes in the composition of their gut bacteria, while the total number of microbial types remained stable.
NewsFreshwater alga captures far-red light for photosynthesis by rearranging ordinary chlorophyll
To survive in areas where it is difficult to photosynthesize, some organisms adopt unique strategies. Researchers have found that a freshwater alga captures far-red light as an additional energy source by arranging ordinary chlorophyll in an extraordinary way.

Corpses leave microbial fingerprints behind in the soil long after they’re gone
Researchers have found that trace elements of a cadaver linger at an original dump site even after an extensive amount of time. These elements can provide insights into postmortem processes, helping forensic investigators uncover clandestine burials and relocate the remains of murder victims.
NewsTicks carrying more than one pathogen are on the rise in US Northeast
Tick-borne diseases are on the rise in the northeastern US, with many ticks carrying more than one pathogen. Most commonly found together were Borrelia burgdorferi and Babesia microti. Co-infection with these two pathogens was more frequent than expected, approaching 11% by the end of the study.
NewsScientists design metal-enhanced biochar to boost clean hydrogen production from agricultural waste
A new study reports that specially engineered biochar made from agricultural waste could significantly increase biohydrogen production by improving the way microbes transfer electrons during fermentation.
NewsIsland birds reveal surprising link between immunity and gut bacteria
Scientists have uncovered a hidden link between gut health and the immune system, all thanks to a tiny island bird. They collected the poo of the Seychelles warbler to analyse their gut bacteria – and found that their immune genes influence which gut microbes thrive.
NewsMachine learning reveals when biochar helps or harms soil life
Researchers have shown that biochar can either help or harm soil organisms depending on how it is produced and applied. The research analyzed results from dozens of previous experiments to better understand how biochar affects plants, microbes, and soil animals.
NewsScientists trace crop viruses back to the last Ice Age
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. Tthe ancestors of modern tymoviruses likely emerged before the last Ice Age, a new study reveals.
NewsTiny vesicles, big risk: Environmental sweeteners trigger antibiotic resistance transfer
A new study reveals that mixtures of artificial sweeteners can stimulate soil bacteria to release microscopic extracellular vesicles that carry antibiotic resistance genes (ARGs).
NewsShifting from biotic to abiotic drivers of urban microbial multifunctionality under drought and rehydration
Scientists conducting microcosm experiments on Zoysia japonica, a common urban turfgrass, simulated four drought intensities and recovery by rehydration. They analyzed alteration in microbial communities and biochemical cycling to pinpoint the drivers of urban microbial multifunctionality.
NewsSoybeans recruit beneficial soil microbes to defend against major pest
Researchers report that resistant soybean varieties actively recruit beneficial soil microorganisms that help suppress soybean cyst nematode. Even more striking, those protective microbes can be transferred to soil to help defend susceptible soybean plants.
NewsScientists successfully harvest chickpeas from ‘moon dirt’
Scientists have successfully grown and harvested chickpeas using simulated “moon dirt,” the first instance of this crop produced in this medium. They added vermicompost and coated the chickpeas with the fungi arbuscular mycorrhizae before planting.
NewsHidden viral networks in soil microplastics may shape the future of sustainable agriculture
A new scientific review highlights the complex interactions between soil microbes and viruses that occur on the surface of microplastic particles. The study reveals that these microscopic relationships may influence soil health, ecosystem recovery, and the long term sustainability of agriculture.
NewsDiversification of termite diets was made possible by genome modifications
Study reveals that evolutionary divergence occurred before ecological divergence, enabling these insects to feed on both wood and soil. Future discoveries may be applied to the production of biofuels.
NewsOne Health antimicrobial resistance modelling: from science to policy
Researchers have identified fundamental gaps in current mathematical modelling approaches that prevent translation of science into policy, including data limitations, knowledge gaps about AMU-AMR relationships, and the absence of international coordination mechanisms similar to climate change efforts.
NewsNew study reveals how hygienic honey bees show unique advantages in fighting infectious pathogens in adult bees
For the first time, research shows that a key social trait in honey bees is linked to measurable physiological advantages that can improve colony survival. The study uncovers how hygienic honey bee colonies mount stronger individual immune defenses against Nosema ceranae.
NewsPig farm ammonia pollution may indirectly accelerate climate warming, new study finds
A new study shows that ammonia released from intensive livestock farms can significantly increase nearby soil emissions of nitrous oxide, a powerful greenhouse gas that contributes to climate change and ozone depletion.
NewsNitrous oxide, a product of fertilizer use, may harm some soil bacteria
While some nitrous oxide is produced naturally at the plant root, agricultural practices can increase its levels. While it has long been believed that nitrous oxide doesn’t meaningfully interact with living organisms, a new paper shows that it may in fact shape microbial communities.
NewsModified biochar helps compost retain nitrogen and build richer soil organic matter
A new study reports that specially engineered biochar can significantly improve compost quality by reducing nitrogen loss and accelerating the formation of stable humic substances. The findings offer a promising strategy for transforming organic waste into more effective fertilizers while lowering environmental emissions.
NewsGrowing buildings in space: researchers test fungi as construction material for moon, Mars
