NewsSoil bacteria reveal hidden arsenic stress in brick kilns
Researchers collected soils from a shut-down brick kiln area. As arsenic levels increased, bacterial richness and diversity declined, while arsenic-tolerant groups became more abundant. The study also found that bacteria strengthened stress-response pathways and upregulated arsenic-resistance genes.

NewsMicrobes frozen in ancient rubbish heaps help reconstruct ancient Greenlanders’ farms, seal hunts, and toilets
The microbiome of ancient middens in Greenland sheds new light on the daily life of Paleo-Inuit and old Norse communities. Researchers say the middens in the cold Arctic acted like long-term natural experiments, with human- and animal-associated bacterial signals remaining detectable many centuries later.

NewsViruses enhance sulfamethoxazole removal in wetlands by modulating bacteria-phage interactions
A new study examines the role of viruses in sulfamethoxazole (SMX) removal in constructed wetlands. The research demonstrates that the addition of phage-concentrated solutions (PCS) enhances the degradation of SMX by enriching SMX-degrading bacteria.

NewsMicrobes hold the key to unlocking biochar’s carbon storage potential in soils
A new global analysis reveals that tiny soil microbes play a decisive role in determining whether biochar can effectively lock carbon into agricultural soils, offering new insights for climate change mitigation.

NewsChildren with Crohn’s have distinct gut bacteria from kids with other digestive disorders
Researchers have found a “microbial signature” of pediatric Crohn’s disease that differs from the makeup of gut bacteria in children with other gastrointestinal conditions, with Crohn’s patients harboring more pro-inflammatory bacteria and less protective bacteria.

NewsSeashells and coconut char: A coastal recipe for super-compost
Researchers have developed a calcium-modified biochar that speeds up waste recycling and creates nutrient-rich soil, boosting specialized microbial communities that break down tough materials like lignin and convert them into stable humus.

NewsBlack carbon from straw burning curbs antibiotic resistance spread in plastic-mulched farmland
By tracking ARG movement from soil into soybeans, a new study shows that black carbon not only counteracts the ARG-amplifying effects of plastic residues but also limits the transfer of resistance genes into plant tissues and seeds.

NewsNew study reveals how a common antibiotic disrupts nitrogen cycling and boosts greenhouse gas emissions in estuaries
Antibiotics may have far reaching impacts on wetland chemistry, according to a new study that identifies the bacteria responsible for breaking down the antibiotic sulfamethoxazole and links this process to increased emissions of nitrous oxide, a potent greenhouse gas.

NewsBiochar boosts black soil health and crop yields, study finds
A long-term field study conducted in Northeast China’s fertile black soil region has demonstrated that biochar can significantly improve soil health, stabilize microbial communities, and increase crop yields—but only when applied at the right rate.

NewsCan biodegradable mulch films harm soil health?
A new study validates the long-term ecological safety of biodegradable plastic mulch films in temperate maritime climates, breaking the traditional belief that “mulch films increase yield at the cost of soil fertility”.

NewsNew study reveals global warming accelerates antibiotic resistance in soils
A new international study has revealed that climate change is accelerating the rate of development and global abundances of antibiotic resistance bacteria in soils.

NewsOral microbiome varies with life stress and mental health symptoms in pregnant women
The number and type of microbes present in the saliva of pregnant women differ according to whether they are experiencing life stress and symptoms of anxiety, depression and post-traumatic stress disorder (PTSD), finds a study published in the open access journal BMJ Mental Health. Although several studies ...
