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.

Stinkbug leg organ contains symbiotic fungi to shield eggs from parasitic wasps
What looked like a hearing organ on a tiny stinkbug’s leg turned out to be something far stranger: a fungal nursery that mother bugs use to coat their newly laid eggs in protective symbiotic hyphae, shielding their offspring from parasitic wasps.

NewsAnts alter their nest networks to prevent epidemics, study finds
Ants make a series of clever architectural adjustments to their nests to prevent the spread of disease, new research has found. Nests built by colonies exposed to disease had far more widely spread entrances and were more separated, with fewer direct connexions between chambers.
NewsAfrican wildlife poop sheds light on what shapes the gut ecosystem
A study of elephants, giraffes and other wildlife in Namibia’s Etosha National Park underscores the ways in which the environment, biological sex, and anatomical distinctions can drive variation in the gut microbiomes across plant-eating species.
NewsIn chromosome of key biotech bacterium, different setups bring different strengths
New research has found that the effectiveness of biotech bacterium Agrobacterium tumefaciens’ virulence varies, depending on how its chromosome is arranged.

Friendly soil microbes can boost protein in staple crops
Researchers investigated how a bacterium naturally found in the soil that is beneficial to human health can enhance the levels of the amino acid and antioxidant ergothioneine in spring wheat.
NewsIUCN members choose science and ethics in landmark vote on synthetic biology
The Wildlife Conservation Society (WCS) has hailed the adoption of Motion 87, supporting the responsible, evidence-based use of synthetic biology, at the IUCN World Conservation Congress in Abu Dhabi as a historic milestone for global conservation policy.
NewsBiochar shows big promise for climate-friendly soil management
Turning agricultural and organic waste into biochar could help store more carbon in the soil and slow climate change, according to a new study. Recent findings show that biochar improves soil health, boosts microbial diversity, and captures carbon.
NewsSynthetic biology reprograms plant–microbe partnerships for resilient agriculture
By integrating engineering principles with plant biology, a new review highlights how redesigned genetic pathways and plant-based biosensors can deepen understanding of plant responses to both harmful and beneficial microbes.
NewsAlgae and water fleas in lakes: Light color influences food webs
Phytoplankton are the basic food source for many aquatic organisms. A new study shows that the light spectrum is more important for these microalgae and for lake ecosystems than previously assumed.
NewsWetland plant-fungus combo cleans up ‘forever chemicals’ in a pilot study
From a greenhouse study, researchers report that moisture-loving yellow flag irises and fungi on their roots are a promising combination for PFAS removal. As part of a constructed wetland, this pair could effectively treat contaminated wastewater.
NewsFertilizer boosts soil’s ability to lock away carbon
The 180-year experiment at Rothamsted — the world’s longest-running agricultural trial — has revealed that long-term application of nitrogen and phosphorus fertilisers can significantly increase the amount of carbon stored in farmland soils, helping to mitigate climate change.
NewsNew study reveals diverse threats from Avian E. coli
New research has determined why various strains of Avian Pathogenic E. coli behave so differently. The study analysed a colibacillosis outbreak in turkeys in the UK, and found a strain called ST-101 was the dominant cause of the outbreak, accounting for nearly 60% of cases.
NewsStructural diversity of pyripyropenes via biosynthetic gene cluster design and heterologous expression in Aspergillus nidulans
Researchers have designed a reconstituted biosynthetic gene cluster (BGC) for producing structurally diversified deacetylated pyripyropenes, using the native pyripyropene A BGC from the wild-type strain Aspergillus fumigatus Af 293 as a template.
NewsLake Tahoe algae experiment suggests seasonal shifts ahead
As the climate warms and nutrient inputs shift, algal communities in cool, clear mountain lakeswill likely experience seasonal changes, according to a new study. The effects of climate warming were especially pronounced in the colder months.
NewsValorization of soybean-processing wastewater sludge via black soldier fly larvae: performance and bacterial community dynamics
A new study indicates that the valorization of soybean-processing-sourced sludge via black soldier fly larvae was achieved via functionally important BSFL intestinal microbiota, providing an efficient recycling approach for similar waste streams.
NewsRoot chemistry determines how antibiotic resistance spreads from manure to crops
Researchers found that the rhizosphere, the narrow soil zone surrounding plant roots, is a major hotspot for the accumulation of manure-derived ARGs. Across eight common crops, ARG abundance in rhizosphere soil was on average 1.24 times higher than in bulk soil.
NewsFreshwater snails are an overlooked reservoir of AMR, study reveals
Freshwater snails across Africa and the UK carry bacteria containing a wide range of antimicrobial resistance (AMR) genes, including those predicted to confer resistance against last-resort antibiotics, according to a new study led by AMI members.
