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.

NewsUse of controversial weedkiller inadvertently selects for drug-resistant bacteria that can spread to hospitals
Scientists have found evidence that the spread of AMR isn’t always driven by bacteria evolving to resist the antibiotics themselves: rather, certain weedkillers can have the same effect.
NewsStolen chloroplasts maintained by host-made proteins offer clues to plant cell origins
The single-celled predator Rapaza viridis temporarily retains chloroplasts from prey algae and imports its own proteins into them, new research has shown.

Selenium nanoparticles and glutathione synergistically enhance soybean salt tolerance by activating the JA pathway and arbutin-mediated rhizosphere microbiota
Researchers addressing soil salinity have developed a novel nano-biostimulant, a synergistic composite offering a new paradigm for enhancing salt tolerance by coordinating the plant’s endogenous signaling pathways with the functions of its rhizosphere microbial community.
NewsField-portable assays help scientists study and explore caves
A new study shows that field-portable assays are effective at identifying microbes directly in the field in real time, making it easier to study and explore caves. The researchers established a roadmap for thoroughly studying cave life, emphasizing the need to sample widely and from different materials.
NewsSingle-cell sequencing reveals unexpected protist diversity
Scientists developing a single-cell sequencing pipeline have revealed previously unknown diversity from a group of free-living protists closely related to the parasites that cause sleeping sickness.
NewsEngineered biochar and beneficial bacteria team up to boost crop growth
Researchers have developed a specially engineered biochar made from sewage sludge that, when combined with beneficial bacteria, significantly enhances plant growth by improving how crops absorb nitrogen.
NewsBiochar’s climate promise depends on soil type: Cuts N₂O in dry fields but boosts it in rice paddies
By tracing the exact microbial pathways responsible for N₂O production, the scientists reveal why the same soil amendment produces opposite climate outcomes under different land uses.
NewsBiochar particle size found to shape disease control in crops
Researchers have discovered that the particle size of biochar determines how effectively and how long it can suppress soil-borne pathogens, offering new insights for sustainable agriculture.
NewsDiet determines the bacteria present in microbial gardens cultivated by ants
Researchers studying leafcutter ants have demonstrated how bacteria in the colonies respond to different diets provided by ants to the fungi they cultivate. The study paves the way for a better understanding of how colonies function and may lead to the discovery of new molecules for biotechnological use.
NewsBird flu risk to Danish cattle – new tool can warn farmers before infection spreads
Researchers have developed a tool that can predict where and when the risk of infection is highest. The tool is based on infection data from the U.S. outbreaks and adapted to a Danish context.
NewsBiochar’s climate benefits may reverse over time in acidic soils, new study finds
A study reveals that biochar can both decrease and increase emissions of nitrous oxide, a potent greenhouse gas, depending on how long it has been in the soil. The findings highlight the importance of considering long-term impacts when evaluating climate solutions.
NewsA newly identified disease of corn and sorghum may be mistaken for iron deficiency
A newly identified bacterial disease affecting corn and sorghum can closely resemble iron deficiency, potentially leading farmers to apply costly nutrient treatments that do not address the underlying problem.
NewsLong-term biochar use reshapes soil carbon storage through microbial pathways
A new long-term study reveals that biochar, a carbon-rich material derived from crop residues, can significantly enhance soil carbon storage, but its effectiveness depends strongly on land use and soil type.
NewsFantastic fungi found with ability to freeze water
An international group of researchers has discovered the identity of fungal proteins that can catalyze ice formation at high subzero temperatures. One potential application of this discovery could be to engineer weather.
NewsStudy identifies causes of potato dry rot in Colorado
Researchers have identified multiple fungal species causing dry rot in Colorado. By analyzing structural and molecular features, plant pathologists identified four Fusarium species associated with potato dry rot – including one that hadn’t previously been found in the U.S.
NewsScientists discover ‘consortium’ of bacteria cooperating to eat phthalate plasticizers that single microbes can’t stomach
Researchers have discovered a synergistic ‘consortium’ of plastic-eating bacteria, which can eat phthalate esters (PAEs) – plasticizers which are often found in building materials, food packages, and personal care products, but have been implicated in hormonal, metabolic, and developmental disorders and some cancers.
NewsTurning agricultural waste into smarter livestock nutrition tools - and an alternative to antibiotics
A new study has found that biochar made from agricultural waste such as chestnut shells and vine prunings could help deliver beneficial compounds more effectively in animal feed, offering a promising alternative to antibiotics in livestock production.
NewsOcean bacteria team up to break down biodegradable plastic
Researchers uncovered the role of individual ocean bacteria in the breakdown of a widely used biodegradable plastic. They also showed the complementary processes microbes use to fully consume the plastic, with one microbe cleaving the plastic into its component chemicals and others consuming each chemical.
NewsWhen waste becomes fertilizer: Can sludge-derived liquids reshape aquatic life in farmlands?
