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.

What happens when a shoreline scavenger consumes microplastics?
Researchers report on what happens when wharf roaches, a common shoreline scavenger, eat expanded polystyrene (EPS). Analysis of the wharf roach gut microbiome showed little change, but several rare microbes were found only in the EPS-fed specimens.

NewsResearchers test far-ultraviolet light to prevent bird flu in poultry
Researchers are preparing to test a new potential line of defense against highly pathogenic avian influenza, HPAI in poultry farming. They will use a form of ultraviolet light called far-UVC, to see if it can kill HPAI, without harming birds on poultry farms.
NewsMicroplastics may act as pollutant shuttles, carrying chemicals, pathogens and antibiotic resistance genes
A new review reveals how microplastics transport multiple pollutants across ecosystems and proposes a framework for identifying when these vector effects become serious ecological threats.
NewsInternational award supports research into fern-microbe symbiosis
Dr Sophie de Vries will combine evolutionary genomics with experiments that pair ferns and different microbes, to investigate how plants fight off “foes” (diseases) at the same time as supporting their beneficial “friendships” (bacterial partners).

bZIP transcription factor AflHapX coordinates iron homeostasis and aflatoxin biosynthesis in Aspergillus flavus
Researchers have identified the bZIP transcription factor AflHapX in Aspergillus flavus by searching its genome with the HapX protein sequence from Aspergillus fumigatus. They discovered that AflHapX is critical for A. flavus’s adaptive response to both iron excess and iron starvation.
NewsIndy gene reduction linked to healthier gut microbiota and longer lifespan in fruit flies
Scientists investigating aging have shown that Indy reduction is associated with lower bacterial load and higher bacterial diversity in aging Indy flies compared to controls.
NewsSulfur-reducing mechanism of bacterial selenoprotein discovered
A newly discovered multiheme enzyme in Geobacter sulfurreducens contains selenocysteine, which is encoded by a recoded UGA stop codon in the bacterial genome. This enzyme uses a unique selenium–sulfur–heme catalytic center to reduce polysulfides during elemental sulfur respiration.

The UK Health Security Agency (UKHSA) is undertaking enhanced surveillance and trapping activities following the detection of invasive Aedes aegypti mosquitoes and larvae at nearby residential properties in east London.
NewsUnderground methane leaks may cultivate microbes that help consume them
Researchers have identified where naturally occurring soil microbes consume methane released from underground natural gas leaks. Methane-consuming microbes were most active in a narrow zone near the surface where methane rising from below meets oxygen entering from the atmosphere.
NewsAn enzyme with potential: New type of plastic-degrading enzyme discovered in bacteria
Researchers have identified a new enzyme that can not only degrade certain polyesters and bioplastics, but also might provide bacteria with resistance to antibiotics. The discovery raises hopes that microorganisms can adapt to plastic degradation more rapidly than previously thought.
NewsWild tomatillos coat fruits with sticky chemical arsenal, study finds
For decades, research on plant chemical defenses has focused on glandular trichomes—the tiny hair‑like structures on leaves and stems that produce and secrete protective compounds. Acyl sugars, a class of specialized metabolites widespread in the nightshade family (Solanaceae), are known to deter insects and fungal pathogens when produced in leaf ...
