NewsA new gateway to global antimicrobial resistance data
To support global AMR research, EMBL’s European Bioinformatics Institute (EMBL-EBI) has launched the AMR portal, a central hub that connects bacterial genomes, resistance phenotypes, and functional annotations, all in one place. The AMR portal ensures long-term availability, standardisation, and reusability of AMR data.

NewsMicrobial teamwork slashes uranium pollution in just 48 hours
A research team has developed a synthetic microbial consortium that completely reduces soluble uranium [U(VI)] to insoluble U(IV) within 48 hours, showing nearly twice the efficiency of a single-strain system. The study reveals how Shewanella oneidensis MR-1 and Pseudomonas aeruginosa LXZ1 cooperate to accelerate extracellular electron transfer (EET).

NewsThe leading causes of mass mortality events in sea urchins are pathogens, storms, and extreme temperatures
Researchers have identified the primary drivers of sea urchin mass mortality events over recent decades: pathogens, storms, and extreme temperatures. The team have developed an innovative method for genetic sampling in marine environments - using a swab similar to a COVID-19 test, to enable rapid and non-invasive monitoring of marine animals and underwater disease outbreaks.

NewsAncient chemical clues reveal Earth’s earliest life 3.3 billion years ago
A new study uncovered fresh chemical evidence of life in rocks more than 3.3 billion years old, along with molecular traces showing that oxygen-producing photosynthesis emerged nearly a billion years earlier than previously thought. Researchers paired cutting-edge chemistry with artificial intelligence to reveal faint chemical “whispers” of biology locked inside ancient rocks.

NewsTraces of bacteria inside brain tumors may affect tumor behavior
Scientists have uncovered unexpected traces of bacteria within brain tumors. This discovery offers new insights into the environment in which brain tumors grow and sets the stage for future studies seeking to improve treatment outcomes.

NewsResearchers identify mangrove tree stems as previously underestimated methane source offsetting blue carbon benefits
A new study reveals that mangrove tree stems represent a significant yet previously underestimated source of methane. Additionally, stem emissions showed a strong correlation with soil methane fluxes, indicating that methane produced by anaerobic microbial activity in mangrove soils is transported upward through specialized aerenchyma tissues within the trees.

NewsNext-generation microbiome medicine may revolutionize the treatment of Parkinson’s and similar disorders
Scientists have engineered the probiotic bacterium Escherichia coli Nissle 1917 as a drug-delivery system that continuously produces and delivers the gold-standard Parkinson’s drug Levodopa, which is converted to dopamine in the brain. E. coli Nissle strain was chosen for its century-long record of safely treating gastrointestinal disorders in humans.

NewsWild birds are driving the current U.S. bird flu outbreak
Researchers traced the introduction and spread of highly pathogenic H5N1 viruses during the first 18 months in North America using genomic sequencing and migratory flyway analysis, discovering that the viruses were spread primarily by wild migrating birds.

NewsNew bioelectroceutical platform triggers dual cell death, reverses immunosuppression in colorectal cancer
Scientists have developed a new “microbial fuel cell” platform that integrates electrogenic bacteria with piezoelectric nanoparticles to cooperatively eradicate colorectal tumors, reverse immunosuppression, and remodel the gut microbiome.

NewsBacterial scents behind oak tree decline may be luring deadly beetles
The deadly decline of Britain’s native oak trees may be driven by an unexpected accomplice: their own smell. Scientists have discovered that trees affected by Acute Oak Decline (AOD) emit distinct odours that are highly attractive to the beetle Agrilus biguttatus, a key contributor to the decline.

NewsWomen are three times more likely than men to get severe long COVID: Here’s why
Researchers have identified a distinct immune signature in female long Covid patients versus male patients. They found evidence of ’gut leakiness’ in the women patients, including elevated blood levels of intestinal fatty acid binding protein, lipopolysaccharide, and the soluble protein CD14 — all signs of gut inflammation that can then trigger further systemic inflammation.

NewsEveryday levels of antibiotics in the environment may accelerate the global spread of resistance, new study finds
A new study shows that even very small amounts of antibiotics that commonly appear in soil, rivers, wastewater, and agricultural runoff may significantly accelerate the spread of antibiotic resistance genes among bacteria.

NewsNew blueprint for nature’s carbon-capturing nanomachines revealed
Researchers have uncovered how bacterial organelles assemble, opening new routes for bioengineering and climate innovation. The team has unveiled the most detailed picture yet of how bacteria construct microscopic compartments known as carboxysomes – natural nanomachines that play a vital role in capturing and converting carbon dioxide (CO₂).

NewsExperts urge continued hepatitis B vaccine birth doses for newborns
In a new commentary, leading experts urge that all newborns in the United States continue to receive the first dose of hepatitis B vaccine within 24 hours of birth. Hepatitis B vaccines are safe and effective with over one billion doses administered worldwide.

NewsPredicting the development of biological communities in different kinds of ecosystems
Researchers tested a mechanistic consumer-resource model and confirmed its high predictive capacity. Using the model, the researchers refined current rules on the coexistence of species, too. Their findings can be applied to any situation in which communities of organisms compete for resources.

NewsNew study reveals microbial network restructuring mitigates long-term soil carbon emissions from warming
Scientists conducted a decade-long study that uncovered a previously unrecognized buffering mechanism in subtropical forest soils mitigating the effects of climate warming.

NewsFungal oxalic acid dampens plant immunity through targeting CERK1 deamidation
Scientists found that oxalic acid was a critical virulence factor for both S. sclerotiorum and B. cinerea during their infections of Arabidopsis plants. Further characterizations revealed that OA-mediated virulence in these fungal pathogens was contingent on CERK1.

NewsNew DNA analysis approach could transform understanding of disease evolution
By adapting techniques originally used to study ancient DNA from archaeological specimens, researchers were able to recover genetic information from nearly century-old medical samples.

NewsAvian flu halves South Georgia’s breeding elephant seal population
South Georgia’s breeding population of female southern elephant seals (Mirounga leonina) may have been halved by highly pathogenic avian influenza virus (HPAIV), finds new research. These losses may threaten the security of the island’s breeding population.

NewsThe link between the gut microbiome and autism is not backed by science, researchers say
There’s no scientific evidence that the gut microbiome causes autism, a group of scientists argue in an opinion paper. They warn that conclusions that supported this hypothesis are undermined by flawed assumptions, small sample sizes, and inappropriate statistical methods.
