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.

NewsThe climate crisis threatens river microbial biodiversity
A study warns that the biodiversity and biological functions of aquatic fungi in rivers are at risk due to rising temperatures, prolonged dry periods and the loss of riparian vegetation caused by climate change.
NewsA soil bacterium turns electricity and carbon dioxide into acetate
A new study shows that a soil bacterium can directly reduce Fe(III) minerals, exchange electrons with electrodes, and use electrode-derived electrons to convert carbon dioxide into acetate under autotrophic conditions.
OpinionFungi that inspired The Last of Us may hold the key to a pesticide-free agriculture
They may be the stuff of our nightmares, but Aditya Singh Ranout reveals how invisible allies underneath our feet in the form of entomopathogenic fungi are transforming agriculture - and why these fascinating microbes may hold the key to a pesticide-free agriculture.

Native litter jump-starts microbial recovery in mine soils
By applying litter collected from nearby native woodland to rehabilitated mine land, a study has shown increases in microbial diversity, enrichment of carbon- and nitrogen-cycling microorganisms, and stronger biochemical potential for soil organic matter decomposition and nitrogen mobilization.
NewsNatural symbiosis: How plants and microbes share vital nutrients in fragile ecosystems
Researchers using stable isotope labelling to investigate how different forms of nitrogen are used by plants and microbes in alpine heath environments found that plants and microbes use distinct strategies to access this critical nutrient.
NewsMicrobes reveal how tillage shapes soil carbon storage
A new study on maize fields in Jilin Province, China, found adding organic carbon sources on top of straw had different effects on the organic carbon in the topsoil in comparison to the subsoil.
NewsResearchers aim to autonomously eliminate plant-killing bacteria from hydroponic farming systems
Three researchers have received a nearly $600,000 grant from the U.S. Department of Agriculture to develop a system that can autonomously detect and remove crop-killing microbes from hydroponic farms before they cause damage to plants.
NewsTea’s molecular shield against anthracnose
Researchers investigating inducible immune mechanisms activated by tea plants after pathogen infection said the findings show that tea anthracnose resistance is not simply a matter of possessing a resistance-related gene, but of how strongly and rapidly the plant activates its defense network.
NewsTracking melanoidins to improve food-waste biogas recovery
Higher pretreatment temperatures in food-waste biogas recovery can promote Maillard reactions, generating melanoidins. A study shows that melanoidins increase with hydrothermal temperature and inhibit methane production by disrupting methanogenic microbial communities.
NewsMovement of “forever chemicals” through the Great Lakes
New analysis of 42 years worth of biological records from the Great Lakes, unveils how per- and polyfluoroalkyl substances (PFAS) or “forever chemicals” have moved across the region, contaminating a variety of wildlife.
NewsCaught in the act: A gene jumps into the void
Self-splicing introns are a special group of jumping genes. It is more difficult for a gene to jump into another cell or another species. Until now, it had been assumed that, for this to happen, the jumping genes travelled as ‘hitchhiker’ in the genomes of plasmids or viruses, but researchers have made a surprising observation.
NewsHow H5N1 bird flu hid unrecognized for weeks in dairy cattle
A new study reveals why H5N1 influenza infection looked so different in dairy cows, offering a framework for spotting new host species quickly. Instead of affecting the lungs, it caused severe infection in the cows’ udders, largely sparing the lungs.
NewsBiochar-coated catalyst turns wet microalgae into cleaner fuel-building chemicals
Turning microalgae into usable liquid fuels remains difficult because algae-derived bio-oil often contains high levels of oxygen and nitrogen compounds. A new study reports a promising strategy to address this challenge.
NewsThree interlinked factors are needed to sustainably grow microbes for MICP
A new review investigates cost-effective and greener ways to grow microorganisms for use in Microbially Induced Calcium Carbonate Precipitation (MICP), a microbial process that precipitates calcium carbonate, and identifies three interlinked factors that determine success or failure.
NewsScientists just found something weird inside moss - an unexpected fungal roommate
According to new research, mosses have also been hiding something. Researchers studying desert mosses have found evidence that these ancient plants may host fungi inside their tissues. This relationship has not previously been documented.
NewsThe drive to protect Missouri’s $4 billion cattle industry from tick threats
A tiny parasite-carrying tick is posing an outsized threat to Missouri’s cattle. Now, researchers are stepping in to protect the state’s $4 billion cattle industry by tracking different ways the American dog tick spreads a deadly disease known as bovine anaplasmosis.
