NewsResearchers develop realistic ‘mock’ samples to speed cervical cancer test development
A team of bioengineers has developed a new way to create highly realistic “mock” patient samples that could help accelerate the development of faster, more accessible cervical cancer screening tests for low-resource settings.

NewsSunlight and PVC pipes create a hidden driver of antibiotic resistance
New research shows that chemicals leaching from everyday PVC—especially after exposure to sunlight—can dramatically speed up the spread of resistance genes between bacteria. The effect was strongest at low to moderate concentrations, where the leachate triggered bacterial stress responses without killing the microbes.

NewsFungus-powered farming: Bigger harvests, better taste
Researchers have identified a natural, eco-friendly way to significantly increase agricultural yields while also improving the quality and taste of produce. The study focuses on an extract derived from the yeast-like fungus Pseudozyma aphidis.

NewsEurope advances genomic surveillance of CCRE with landmark multi-country study
New survey results provide the most comprehensive genomic picture to date of carbapenem- and/or colistin-resistant Enterobacterales (CCRE) across hospitals in Europe.

NewsThe hunt for red: Chromatin-mediated upregulation of Monascus pigments in Talaromyces purpurogenus OUCMDZ-019 via disruption of Ash2
The industrial application of Monascus pigments has been hindered by three key bottlenecks: unstable yield, poor environmental stability, and the risk of contamination by citrinin. Researchers adopted an epigenetic derepression strategy to unlock the hidden biosynthetic potential of MPs in Talaromyces purpurogenus OUCMDZ-019.

NewsFlu signals in wastewater offer an early warning for community outbreaks
A research team has demonstrated that measuring influenza viral RNA in wastewater can be used to estimate community influenza incidence. The approach may help identify outbreak trends about one week earlier than publicly available patient report data.

NewsTiny molecules unlock big gains in soil health
By adding lignin- and humus-based small molecules (LSMs and HSMs) to straw-amended soils, researchers observed remarkable gains in the formation of stable mineral- and particulate-associated carbon, driven by shifts in microbial communities and enhanced cross-trophic interactions.

NewsThe fog is alive - with tiny helpers
What if fog isn’t just misty air, but a living ecosystem? This question hung over cloud researcher Thi Thuong Thuong Cao. As a PhD student at Arizona State University, her curiosity led her from knocking on the doors of microbiologists and chemists, to sampling fog before sunrise in Pennsylvania, to ...

NewsBody weight affects your gut microbiota
A new study demonstrates that there is a correlation between gut microbiota and body weight. Researchers also observed that having a high BMI is detrimental to gut microbiota.

NewsNo-till, new rules: Soil microbes thrive in conservation farming
Long-term conservation tillage (CT) is transforming the way soil microbes responsible for nitrogen fixation behave and interact. Compared to conventional tillage, CT fosters a less competitive yet more robust microbial ecosystem, with soil depth and nitrogen levels playing pivotal roles.

NewsDoes agriculture and climate affect feeding activities of soil animals?
An international research team has shown that soil animal communities have greater trophic diversity in agricultural ecosystems and in tropical regions. Animals that feed on microorganisms – such as nematodes, springtails and mites – had higher trophic diversity than those that feed on dead organic matter or live as predators.

NewsProtists and bacteria form secret alliance to stop fusarium wilt
Scientists have uncovered how phagotrophic protists team up with beneficial bacteria to suppress watermelon Fusarium wilt. Through microbial sequencing and ecological network analysis, they found that nutrient imbalance disrupts these partnerships, allowing the fungal pathogen to spread.

NewsInvasion, restoration, and the surprising season for soil life
Microbes beneath our feet quietly orchestrate the health of ecosystems, but their seasonal rhythms remain a mystery—especially in coastal wetlands. A new study uncovers a surprising twist: microbial diversity and interaction networks are richer and more intricate in winter than in summer.

NewsAging immune systems show reduced ability to clear tuberculosis during treatment
Immunosenescence increases susceptibility to infectious diseases like tuberculosis (TB) in older adults and hinder effective containment of Mycobacterium tuberculosis during therapeutic intervention.

NewsSoil science reimagined: From farmland to the final frontier
A new perspective offers a compelling call to reimagine the future of soil science. The article outlines a conceptual framework for “nontraditional soil science,” encompassing diverse fields from urban engineering to forensic soil analysis and planetary exploration.

NewsCommentary: Dengue viral infection and associated liver disease
A new commentary highlights the time course of serological and liver enzyme elevations in mild versus severe dengue, emphasizes early recognition of progression to acute liver failure, and reviews current vaccination and prevention strategies.

NewsMicrofossils interpreted as animal traces were actually algae and bactéria
A reexamination of microfossils found in Brazil shows that the marks previously interpreted as traces of worms or other small oceanic animals are actually communities of fossilized microscopic bacteria and algae.

NewsStudy reveals how strawberries and raspberries were ambushed by fungal parasites
Plant diseases often arise when the pathogens that cause disease are introduced into new territories where native plants don’t recognize the pathogen and therefore may have minimal defenses against it. But how often does the reverse happen?

NewsFrom ocean to gut: The bacteria that shape both human health and marine carbon cycling
A group of researchers has discovered that Akkermansia bacteria are not unique to our guts, but can also be found in the ocean. In both habitats they use similar skills to ensure their survival and success. They seem to carry an old and widespread survival toolkit.

NewsScientists discover ‘hidden switch’ in immune cells that helps the body kill deadly fungus
Scientists have discovered a “control switch” inside our immune cells that helps the body destroy dangerous fungal infections. A protein called RAB5c helps white blood cells kill Aspergillus fumigatus – an airborne fungus that can cause life‑threatening lung infections in people with weakened immune systems.
