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.

Aboard the International Space Station, viruses and bacteria show atypical interplay
In a new study, terrestrial bacteria-infecting viruses were still able to infect their E. coli hosts in near-weightless “microgravity” conditions aboard the International Space Station, but the dynamics of virus-bacteria interactions differed from those observed on Earth.

NewsScientists observe infections by cancer-causing retroviruses in koalas as they occur
Scientists analysed the ongoing colonization by two retroviruses of the germline of koalas and resulting deaths from cancer in multi-generational pedigrees of over 100 koalas in US and European zoos. They calculated genetic risk scores (GRS) that can help guide koala breeding programs.
NewsBirding enthusiasts can help songbirds avoid salmonella epidemics
Biologists are developing a tool to predict when deadly salmonella outbreaks are likely to happen in wild songbird populations so that people can protect their feathered friends by taking down bird feeders at the right time.
NewsRare microbial wrinkle structures - signs of ancient life - turn up in an unexpected place
Deep water sediment layers in the Dadès Valley in the Central High Atlas Mountains of Morocco have revealed rare microbial wrinkle structures formed far from sunlight.

Vaccine against foot-and-mouth disease could deliver $1.3 billion a year in global livestock benefits
A new foot-and-mouth disease vaccine is projected to deliver over $1.3 billion in annual benefits and transform global livestock resilience.
NewsCat disease challenges what scientists thought about coronaviruses
Researchers have uncovered new details about how a once-deadly coronavirus disease in cats spreads through the immune system. For years, the prevailing belief was that the virus behind feline infectious peritonitis infected just one type of immune cell.
NewsGamma rays quickly toughen nitrogen‑fixing bacteria
Heat‑resilient biofertilizers could help crops cope with rising temperatures but engineering them has been slow and uncertain. A new study shows that pairing experimental evolution with controlled gamma‑ray mutagenesis can accelerate the path to heat‑tolerant nitrogen‑fixing bacteria.

Many everyday products contain fatty acids from palm oil or coconut oil, but the extraction of these raw materials is associated with massive environmental issues. Researchers have now developed a biotechnological approach that could enable a more environmentally friendly production method.
NewsNew study finds higher hantavirus risk in drier, underdeveloped areas
In a recent study of the contiguous USA, researchers found that the risk of disease from hantavirus is higher in drier, underdeveloped geographic areas with more socioeconomic vulnerability and increased numbers of unique rodent species.
NewsScientists decode tree genome to unlock terpenoid-based disease resistance
Researchers reported a chromosome-scale genome and multi-omics analysis of a Lauraceae medicinal tree. The study reveals how specific terpene synthase (TPS) genes contribute to antimicrobial compound production and enhanced resistance to plant diseases.
NewsEarthworms turn manure into a powerful tool against antibiotic resistance
Earthworms could become unexpected allies in the global fight against antibiotic resistance, by helping farmers turn manure into safer, high-value organic fertilizer through vermicomposting. Researchers report it can remove antibiotic resistance genes far more consistently than conventional composting.
NewsTraditional herb offers new hope for antibiotic-free pig farming
A new review highlights that Houttuynia cordata extract could serve as a multifunctional natural substitute for antibiotics in swine production. Plant-derived flavonoids, volatile oils, and polysaccharides suppress pathogens including Salmonella, PRRSV, and Streptococcus suis.
