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.

Cooperation: A costly affair in bacterial social behaviour?
A new study reveals that population bottlenecks can fundamentally reshape how cooperation evolves and persists in complex microbial societies. Researchers explored how repeated bottlenecks affect cooperative traits of Myxococcus xanthus, a model social bacterium.

NewsNew study uncovers how rice viruses manipulate plant defenses to protect insect vectors
Rather than passively “hitchhiking” within insect vectors, rice viruses actively manipulate plant defense pathways to protect their insect carriers.
NewsPlant-derived phenolic acids revive the power of tetracycline against drug-resistant bacteria
A study demonstrates that plant-derived phenolic acids can act as powerful antibiotic adjuvants by restoring and enhancing tetracycline efficacy against multidrug-resistant bacteria through multi-target disruption of key resistance mechanisms.
NewsResearchers eye goal of turning garden and crop waste into plastics
A research team will combine eco-friendly and application-oriented approaches to develop a cost-effective, energy-efficient technology for making innovative plastics based on polybutylene succinate (PBS) which are made entirely out of organic waste.

Science army mobilizes to map US soil microbiome
A small army of researchers are working to catalog the vast and largely unknown soil microbiome of the United States. The project, one of the biggest microbiome studies ever attempted, has already resulted in the discovery of more than 1,000 new strains of bacteria and never-before-seen microbes.
NewsRice genes matter more than domestication in shaping plant microbiomes
A new study reveals that the specific genetic identity of a rice plant plays a stronger role than whether it is wild or domesticated in determining which microbes it hosts and how those microbes function.
NewsMicrobes that break down antibiotics help protect ecosystems under drug pollution
A new study shows that certain microbes can act as community protectors by breaking down antibiotics and stabilizing entire microbial ecosystems, offering a new way to rethink environmental risk assessment and pollution management.
NewsHow a fungus leads to tissue growths in maize
When a maize plant is attacked by the fungus Ustilago maydis, tumor-like tissue growths occur at the site of infection. How the pathogen causes this response in its host has long been unknown. But a study has now shown how the fungus takes over the plant’s function for forming lateral roots.
NewsBats identified as origin of unexplained acute respiratory illness and encephalitis in Bangladesh
Infectious disease researchers have identified Pteropine orthoreovirus (PRV), an emerging bat-borne orthoreovirus, in archived throat swab samples and virus cultures from five patients in Bangladesh who were initially suspected to have Nipah virus infection but tested negative.
NewsAntibiotics in sediments may quietly boost greenhouse gas emissions
A study shows that pharmaceutical pollution alters nitrogen cycling and greenhouse gas emissions in coastal sediments. Even environmentally relevant antibiotic concentrations increased N₂O release, suggesting that widespread contamination may enhance estuarine climate forcing.
NewsUrban wild bees act as “microbial sensors” of city health
A new study shows that the guts of urban-dwelling wild bees contain detailed microbial signatures that reflect both bee health and the quality of the surrounding environment, offering a powerful new tool for monitoring ecological well-being in cities.
NewsFrom prey to predator: How carnivores spread beneficial fungi
New research reveals that carnivores play an important role in ecosystem function by providing a largely overlooked mechanism for long-distance dispersal of beneficial mycorrhizal fungi.
NewsSoil microbes in Colombia’s páramo and tropical forests respond to seasonal shifts
A new study has demonstrated that microbial communities in the soil of Colombia’s tropical forests and high-altitude páramos are significantly influenced by seasonal changes, particularly during the dry season.
NewsFifteen-year cattle manure application reshapes phoD- and gcd-harboring microbiomes, enhancing vegetable yields
A new study demonstrates that combined manure and chemical fertilizer (M+CF) in an open-field lettuce cropping system enhanced both diversity (+45.3%) and abundance (+290%) of gcd-harboring bacteria.

Dr. Taniya RoyChowdhury, a soil microbial ecologist and biogeochemist at the Woodwell Climate Research Center, describes a typical day.
NewsTurning crop waste into precision weapons against waterborne pathogens
Researchers have developed a novel class of biomass-derived carbon dots that selectively eradicate Staphylococcus aureus in water, using corn straw to synthesize amine-modified nanomaterials that act as oxidase mimics, enabling targeted bacterial inactivation without harming beneficial microorganisms.
NewsLivestock-induced changes in soil properties and microbial dominance determine soil microbial diversity in a conifer forest
In the critical habitat of the giant panda, livestock grazing is reshaping the invisible yet vital world of soil microbes in an unexpected way. A new study reveals that while grazing alters soil properties, it paradoxically leads to an increase in soil bacterial diversity.
NewsStage-specific microbial dynamics underpin ecosystem restoration on tropical coral islands
Facilitating the establishment of self-sustaining plant communities has become a crucial scientific and technological issue that urgently needs to be addressed in advancing marine ecological civilization and maintaining ecological safety on tropical coral islands.
NewsFungal denitrification dominates soil N2O emissions after vegetation restoration in the Karst region
A new study demonstrates that soil fungal nirK-derived N2O in the karst region are significantly distinct between cropland and forest, soil NO3‒-N and sand are important drivers of the soil N2O emissions variation, especially after vegetation restoration.
NewsAntibiotic resistance is ancient, ecological, and deeply connected to human activity, new review shows
Antibiotic resistance genes are often portrayed as a modern medical problem driven by the overuse of antibiotics in hospitals and farms. A new comprehensive review published in Biocontaminant reveals a much deeper and more complex story. Antibiotic resistance is an ancient feature of microbial life, shaped by millions of years ...
