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.

Leaf spectra reveal hidden nitrogen-fixing nodules in soybean roots
Soybean roots may no longer need to be dug up to reveal how well they are forming nitrogen-fixing nodules. Researchers have shown that hyperspectral signals from leaves can predict below-ground nodule traits, offering a non-destructive way to track plant–microbe partnerships under drought and salt stress.

NewsMigratory birds spread avian influenza to Greenland’s polar bears
Migrating birds that breed in the Arctic are spreading avian influenza to polar bears in eastern Greenland, according to a new study that found evidence of infections in bear blood samples acquired from Greenland Inuit subsistence hunters.
NewsReindeer grazing reshapes the hidden roots of northern forests
Reindeer grazing is reshaping northern pine forests beneath the surface as well as above it. Researchers found nearly 30% less shallow-root biomass in grazed forests, alongside shorter, thicker and less-branched roots, changes that could alter nutrient uptake, soil microbial communities and the way carbon moves through these ecosystems.
NewsOne strain, two jobs: Bacillus amyloliquefaciens SQ1 degrades wheat straw and suppresses aflatoxin-producing Aspergillus flavus
Bacillus amyloliquefaciens SQ1SQ1 functions as a dual-purpose biocatalyst for wheat straw biomass, breaking down cellulose while inhibiting fungal growth, thereby enhancing straw biotransformation, mitigating mycotoxin risk and supporting early crop growth.

’Virus Hunter’ Ken Stedman has been named an International Collen-Francqui Professor for the 2026-27 academic year, an honor the Francqui Foundation reserves for scientists it considers among the best in their field.
NewsBee hives found to be ‘living immune systems’ that protect bees
Researchers have discovered honey beehives act as ‘living immune systems’ that help protect the bee colony, their offspring, and food supplies from disease. In a remarkable example of insect engineering each part of the hive is ‘built in’ strategically across different compartments of the hive.
NewsHow plants unwittingly help fungal pathogens
Infecting a maize plant is no simple task for a fungal pathogen such as Ustilago maydis. A group of researchers has now uncovered how the fungus detects that it has successfully entered its host. This signal triggers changes in fungal growth.
NewsCould plywood provide a better home for oil-degrading microbes?
The material used to support microbial biofilms could influence their potential role in treating water generated during oil production. Researchers examined whether different supporting materials affect the formation, abundance, and composition of biofilms inside a 14-hectare constructed wetland treating oil-produced water.
NewsVirus-based tool opens a faster route to studying cowpea genes
Genome sequencing of cowpea has provided researchers with numerous candidate genes, and genetic transformation has enabled studies of traits such as drought and heat tolerance. A new study reports sustained gene silencing across seven cowpea varieties and demonstrates the system’s utility for investigating jasmonate regulation during leafminer infestation.
NewsTextile and food waste co-digestion boosts methane yields
Anaerobic co-digestion of textile waste with food waste (FW) could turn two stubborn waste streams into renewable methane while reducing landfilling and incineration. A study examined mono- and co-digestion of cotton, polycotton, and wool with FW under mesophilic conditions, testing substrate-to-inoculum (S/I) ratios of 0.5 and 1 and multiple feedstock mixing ratios.
NewsNew platform reveals broad viral exposure histories in pigs
Pigs can retain antibody traces of past viral encounters, yet conventional tests usually examine only a limited number of viruses at a time. Researchers have developed a platform that uses 36,416 short protein fragments from 140 swine-associated viruses to screen many antibody responses in parallel.
NewsManganese-enhanced biochar helps soil retain nitrogen while reducing greenhouse gas emissions
Adding manganese to biochar can help soil retain more nitrogen by strengthening a natural microbial process. Scientists demonstrated that manganese-loaded biochar increased a key nitrogen-conserving microbial process by 2.9 times compared with untreated soil, while substantially reducing emissions of nitrous oxide, a powerful greenhouse gas.
NewsTwo paths to healthier soils: Scientists reveal how straw and biochar store carbon differently
Researchers discovered that combining manure with straw or biochar significantly increased soil organic carbon, but through two distinct pathways. Straw primarily stimulated microbial activity and carbon transformation, while biochar improved soil structure and the physical protection of carbon.
NewsTurning agricultural waste into soil-building substances: Manganese-modified biochar gives fungi a powerful boost
A new study reveals how manganese-modified biochar helps beneficial fungi break down agricultural residues and accelerate the formation of valuable humic substances, offering a promising approach to sustainable organic waste recycling and soil improvement.
NewsBacteria bond grains of sand into architectural elements
Cement manufacturing is one of the largest sources of CO2 emissions in the construction industry. One scientist is researching an alternative that works in a totally different way: instead of firing rocks at over 1,000°C, she is getting bacteria to bond grains of sand together into solid architectural elements.
NewsAspens ‘remember’ past drought in their leaves
Drought may leave more than narrow rings inside a tree trunk. New research suggests quaking aspen can retain a chemical ‘memory’ of dry years, changing the defensive compounds in their leaves and reshaping the fungal communities that live on them long after soils have rewetted.
