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.

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.

Underground 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 ...
