NewsInjectable hydrogel-mediated co-delivery of oncolytic adenovirus and melphalan for retinoblastoma control and vision preservation
The collagen-based hydrogel enabled controlled oncolytic adenovirus and melphalan release and sustained retention. This approach eradicated retinoblastoma tumors and restored normal ocular structure and visual function following intravitreal administration.

NewsVaccine 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.

NewsGut bacteria protect mice with influenza A from bacterial pneumonia, study finds
Select gut bacteria protect mice against post-influenza virus secondary bacterial pneumonia, according to a study which sought to define whether intestinal bacteria influenced some individuals’ vulnerability to secondary bacterial infections following primary respiratory viral infection.
-
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.

NewsTeam shows how viral lysis of blue-green algae enhances ecosystem-scale productivity
Newly published interdisciplinary research shows viral infection of blue-green algae in the ocean stimulates productivity in the ecosystem and contributes to a rich band of oxygen in the water.

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.

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.

NewsThe secret room a giant virus creates inside its host amoeba
Researchers examined Acanthamoeba polyphaga mimivirus-infected amoeba cells using a combination of sequencing methods, including Ribosome profiling to estimate the frequency of translation pausing and tRNA sequencing to determine tRNA composition.
-
NewsNew biosensor technology could transform how viruses are detected
A new review highlights major advances in a promising class of diagnostic tools known as aptamer-based biosensors, which could help deliver faster, cheaper, and more portable virus testing in clinics, communities, and the field.

NewsA single gene underlies begomovirus resistance in eggplant
Researchers identified a gene in eggplant (Solanum melongena) that provides resistance to begomovirus infection. The work reveals a previously unknown defense mechanism and highlights clear biological differences between virus-resistant and virus-susceptible plants.

NewsStudy: How can we stop the spread of flu?
Researchers wanted to find out how the flu spreads, so they put college students already sick with the flu into a hotel room with healthy middle-aged adult volunteers. The result? No one caught the flu.

NewsUshikuvirus: A newly discovered giant virus may offer clues to the origin of life
Researchers have reported the discovery of a giant DNA virus that infects amoeba. Named ushikuvirus after Lake Ushiku in the Ibaraki Prefecture of Japan, where it was isolated. This discovery offers further support for the nuclear virus origin hypothesis.
-
NewsBeyond gene scissors: New CRISPR mechanism discovered
Two studies describe how researchers found a novel CRISPR mechanism, Cas12a2, in a family of nucleases that exclusively cleave DNA. In contrast, Cas12a2 was able to broadly cleave both RNA and DNA.
-
NewsNew study uncovers how rice viruses manipulate plant defenses to protect insect vectors
Rather than passively “hitchhiking” within insect vectors, rice viruses actively manipulate plant defense pathways to protect their insect carriers.

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.
