NewsOral bacterium tied to disability severity in multiple sclerosis
A research team has conducted a study with findings that suggest a potential association between the relative abundance of Fusobacterium nucleatum (F. nucleatum), a bacterium found in the mouth, and disease severity in multiple sclerosis (MS) patients.

NewsFiltering the invisible: New evidence points to more efficient indoor air microbe sampling
Using fluorescence-based detection, a new study provides clear, quantitative evidence that sampling principle, collection medium, and airflow rate strongly shape how well indoor microbial aerosols can be measured.

NewsResearch reveals how ancient viral DNA shapes early embryonic development
New research focuses on a viral transposable element called MERVL. This element becomes highly active for a short window of time when a mouse embryo reaches the 2-cell stage – the point at which a fertilised egg has divided into two cells and switches on its own genome for the first time.

CareersA day in the life of a soil microbial ecologist
Dr. Taniya RoyChowdhury, a soil microbial ecologist and biogeochemist at the Woodwell Climate Research Center, describes a typical day.

NewsResearch links tumor bacteria to immunotherapy resistance in head and neck cancer
Two new studies reveal that elevated levels of bacteria in the tumor microenvironment suppress immune response, driving resistance to immunotherapy in patients with head and neck squamous cell carcinoma.

NewsTurning crop waste into precision weapons against waterborne pathogens
Researchers have developed a novel class of biomass-derived carbon dots that selectively eradicate Staphylococcus aureus in water, using corn straw to synthesize amine-modified nanomaterials that act as oxidase mimics, enabling targeted bacterial inactivation without harming beneficial microorganisms.

NewsResearchers use robotics to find potential new antibiotic among hundreds of metal complexes
Researchers have used a cutting-edge robotic system capable of synthesising hundreds of metal complexes to develop a possible antibiotic candidate - offering fresh hope in the global fight against drug-resistant infections.

NewsNew findings on Candida auris open up potential targets for future therapies
A study shows for the first time that Candida auris uses a CO₂-based metabolic strategy to survive in the nutrient-poor conditions of the skin and to better tolerate antifungal therapies – especially amphotericin B.

NewsLivestock-induced changes in soil properties and microbial dominance determine soil microbial diversity in a conifer forest
In the critical habitat of the giant panda, livestock grazing is reshaping the invisible yet vital world of soil microbes in an unexpected way. A new study reveals that while grazing alters soil properties, it paradoxically leads to an increase in soil bacterial diversity.

NewsStage-specific microbial dynamics underpin ecosystem restoration on tropical coral islands
Facilitating the establishment of self-sustaining plant communities has become a crucial scientific and technological issue that urgently needs to be addressed in advancing marine ecological civilization and maintaining ecological safety on tropical coral islands.

NewsBeing infected or vaccinated first influences COVID-19 immunity
A new study analysing the immune response to COVID-19 sheds light on an important question: does it matter whether a person was first infected or first vaccinated? According to the results, the order of the events does alter the outcome.

NewsFungal denitrification dominates soil N2O emissions after vegetation restoration in the Karst region
A new study demonstrates that soil fungal nirK-derived N2O in the karst region are significantly distinct between cropland and forest, soil NO3‒-N and sand are important drivers of the soil N2O emissions variation, especially after vegetation restoration.

NewsScientists identify potential therapy and diagnostic markers for cerebral malaria
Researchers examined whether methylene blue could mitigate brain injury during severe malaria, and whether a practical set of blood biomarkers could help clinicians identify cerebral malaria early and track how patients respond to treatment.

NewsGeneral intelligence framework to predict virus adaptation based on a genome language model
Researchers have developed a viral risk prediction framework named GIVAL based on the pre-trained viral protein language model vBERT.

NewsAntibiotic resistance is ancient, ecological, and deeply connected to human activity, new review shows
Antibiotic resistance genes are often portrayed as a modern medical problem driven by the overuse of antibiotics in hospitals and farms. A new comprehensive review published in Biocontaminant reveals a much deeper and more complex story. Antibiotic resistance is an ancient feature of microbial life, shaped by millions of years ...

NewsCytomegalovirus breakthrough could lead to new treatments
Researchers have developed a new type of antibody with a modified structure that can outsmart cytomegalovirus and neutralize its ability to evade the immune system.

NewsStudy reveals how ocean’s most abundant bacteria diversify
New research has found that SAR11 marine bacteria are not a single, uniform population as often thought. Instead, they are organized into stable, ecologically distinct groups, essentially specialized “teams” adapted to specific environments, such as the coast versus the open ocean.

NewsThe COVID-19 virus manipulates host cell RNA to shut down the immune system
Researchers have discovered that SARS-CoV-2 uses a sophisticated tactic to evade the human body’s defense system. In addition to evading the immune system before invading the host cell, SARS-CoV-2 manipulates the host cell’s genetic material in a way never before seen in other pathogens.

NewsProtists revealed as key players in soil carbon storage: Dual role uncovered in long-term study
A groundbreaking 27-year field study reveals that how soil protists differentially control fungal and bacterial necromass accumulation—a key process governing SOC storage.

NewsFeeding plant remnants to fungi produces tasty protein to fortify vegan, vegetarian diets
Researchers fed the side streams of carrot production to fungi, generating a sustainable source of protein. They incorporated the new protein into proof-of-concept vegan patties and sausages that testers ranked as tastier than food made from plant-based proteins.
