NewsViruses in wastewater: Silent drivers of pollution removal and antibiotic resistance
New findings suggest that current monitoring strategies, which rely heavily on bacterial indicators alone, may miss critical viral-driven risks and opportunities for safer wastewater reuse.

NewsInternational experts connect infections and aging through cellular senescence
Researchers propose the concept of infection-driven senescence (IDS) to describe the phenomenon in which microbial agents, beyond viruses, can trigger cellular senescence in host cells.

NewsBats identified as origin of unexplained acute respiratory illness and encephalitis in Bangladesh
Infectious disease researchers have identified Pteropine orthoreovirus (PRV), an emerging bat-borne orthoreovirus, in archived throat swab samples and virus cultures from five patients in Bangladesh who were initially suspected to have Nipah virus infection but tested negative.

NewsStudy reveals low immunity against H3N2 strain in Hong Kong; early vaccination urged
Flu activity has surged in many parts of the Northern Hemisphere, driven primarily by a newly emerged H3N2 strain known as ‘subclade K’. Researchers have found that most hospital patients in Hong Kong have little to undetectable levels of neutralising antibodies against this mutated strain.

NewsUrban wild bees act as “microbial sensors” of city health
A new study shows that the guts of urban-dwelling wild bees contain detailed microbial signatures that reflect both bee health and the quality of the surrounding environment, offering a powerful new tool for monitoring ecological well-being in cities.

NewsBacteria resisting viral infection can still sink carbon to ocean floor
Researchers exploring the mechanisms of phage resistance and its effects on the ecological jobs done by ocean bacteria found that some of the mutations studied don’t interfere with the bacteria’s ability to carry out their job of capturing and sinking carbon to the ocean floor.

NewsResearchers develop novel composite copper oxides with strong and stable antiviral activity
Composite copper–lanthanum and copper–yttrium oxides developed by researchers from Japan demonstrate exceptionally high antiviral activity against non-enveloped virus. These oxides are highly stable and achieve over 99.999% viral inactivation in laboratory tests.

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.

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.
-
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.
-
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.

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.

NewsReal-world data gives Africa a smarter path to fighting HIV and TB
African biostatisticians have offered a powerful, data-driven alternative that can accurately inform HIV policy, reduce healthcare costs, and save more lives.

NewsScientists reveal how excess hydrogen triggers metabolic shifts and viral defense in syngas microbiomes
Syngas biomethanation—converting CO/CO₂/H₂ into renewable methane—relies on coordinated microbial interactions. A study reveals that excess hydrogen disrupts this balance, reducing methanogenesis efficiency and triggering major shifts in microbial metabolism and viral dynamics.

NewsSilent dengue infections may hold clues to future vaccine design, study finds
Researchers report the first single-cell immune atlas of asymptomatic dengue, offering a rare look at how the immune system can defeat the virus without triggering illness. The work could help guide the design of safer and more effective dengue vaccines.

NewsEvaluation of antiviral activity of organic–polyoxometalate hybrids based on berberine against encephalomyocarditis virus in vitro
A new study promotes the development of POM-based drugs for clinical application by controlling the organic cations on the surface of organic–POM hybrids, ultimately yielding new POM drugs with high efficiency and low toxicity.

NewsAs US measles cases rise, views of MMR vaccine safety and effectiveness – and willingness to recommend it – drop
As U.S. measles cases rise, a new nationally representative panel survey finds a small but significant drop in the proportion of the public that would recommend that someone in their household get the MMR vaccine, which protects against measles, mumps, and rubella.

NewsGlobal study to evaluate whether dengue outbreaks can be anticipated earlier
Thousands of dengue forecasting models have been published, but few have been tested in real public-health settings. E-Dengue is a new open-source, user-friendly software system tailored for district-level decision-making.

News4 million euros for study with personalized phage therapy
UMC Utrecht has received a grant of 4 million euros for the first clinical study in the Netherlands involving a customized therapy with bacteriophages for patients with recurrent urinary tract infections.
