NewsDengue vaccine remains 80.5% effective against severe cases after five years
The tetravalent dengue vaccine was 80.5% effective against severe dengue cases with warning signs over a five-year period. Overall, the vaccine was 65% effective in preventing symptomatic dengue (caused by any serotype) during the five years of monitoring.

NewsSeaweed has the potential to create a shield to block norovirus infection
Seaweed has certain properties which have the ability to create a shield within the human body, effectively blocking norovirus infection. Fucoidan, from brown seaweed, showed the strongest and most consistent blocking activity against two major norovirus strains, GII.4 and GII.17.

NewsScientists trace crop viruses back to the last Ice Age
Long before humans cultivated crops or sailed between continents, a group of plant viruses was already evolving among wild plants in Eurasia. Tthe ancestors of modern tymoviruses likely emerged before the last Ice Age, a new study reveals.

NewsRecent pandemic viruses jumped to humans without prior adaptation, study finds
A large-scale evolutionary analysis shows most zoonotic viruses emerge without prior adaptation, while passing through a laboratory leaves detectable genetic signatures, offering a new tool to interpret outbreak origins.

NewsMpox immune test validated during Rwandan outbreak
An antibody test for the infectious disease Mpox was successfully developed during the new clade 1b outbreak in Rwanda, the first time that an assay of its kind has been validated within this setting.

NewsHerpes virus fluidizes cell nuclei to multiply faster
A new study finds that herpes simplex virus uses a protein called infected cell protein 4 (ICP4) to make the human nucleus more fluid-like, which in turn makes it easier for the virus to replicate itself. Blocking the ability of ICP4 to fluidize the nuclear compartment caused a drop in viral copy production.

NewsHidden viral networks in soil microplastics may shape the future of sustainable agriculture
A new scientific review highlights the complex interactions between soil microbes and viruses that occur on the surface of microplastic particles. The study reveals that these microscopic relationships may influence soil health, ecosystem recovery, and the long term sustainability of agriculture.

News How viruses mess with our brains
What impact does a viral infection have on our memory, attention, and concentration? A new review has identified several biological markers associated with cognitive decline in the context of infection. It also provides a solid foundation for future research.

NewsHow microbes protect the lungs against allergies
A study has revealed that microbes protect the lungs from subsequently developing allergies and asthma. This long-term protection is “memorized” not by immune system cells but by fibroblasts, structural cells in the lungs.

NewsScientists identify more effective way to detect poultry viruses in live markets
Scientists have found that viruses circulating in live poultry markets can be detected more effectively by sampling the surrounding environment than by testing individual birds. The study shows that environmental sampling can uncover a broader range of poultry viruses.

NewsStudy warns of underrecognized Lassa Fever threat with global implications
A new study shows an urgent need for improved detection and treatment of Lassa fever. The study in Liberia found a high prevalence of Lassa fever among febrile admissions: 11% of patients with fever had Lassa fever despite not being suspected clinically.

NewsResearchers identify ‘neuroimmune signature’ that can predict viral hepatitis complications
A network of genes linked to the nervous and immune systems can predict cancer risk and even explain symptoms such as fatigue and depression resulting from viral hepatitis infection.

NewsStudy finds natural fungal supplement improves COVID-19 vaccine response
Researchers have found that a natural fungal supplement taken at the time of COVID-19 vaccination reduced short-term vaccine side effects and helped antibodies last longer in people who had not previously been exposed to the virus.

NewsNew tool reveals the secrets of HIV-infected cells
Scientists have developed a novel tool—named HIV-seq—for profiling the features of rare HIV-infected cells from people with HIV. Using the new tool, they’ve found key differences in people’s HIV-infected cells before versus after starting antiretroviral therapy.

NewsNanoparticle vaccine approach takes on a new target: Hepatitis C virus
Scientists have engineered a native-like, stabilized version of Hepatitis C virus’s E1E2 complex and used it to build a nanoparticle-based vaccine candidate. It uses a technology called self-assembling protein nanoparticles, which organizes copies of the proteins into virus-like clusters that the immune system can recognize.

NewsHuge toll: Bird flu rampant among black vultures
More than four out of every five dead black vultures examined by University of Georgia researchers tested positive for highly pathogenic avian influenza, according to a new study. Their indiscriminate scavenging appears to sustain transmission of the virus beyond the typical bird flu season.

News10 Years, 70% shift: Wastewater upgrades quietly transform river microbiomes
Researchers investigated how the upgrade of a WWTP influenced nitrogen-cycling microorganisms and DNA viruses in its receiving river. The research compared the river whose WWTP was upgraded during the study period against the river whose upgrade occurred prior to the study.

NewsScientists identify therapeutic target that would curb the spread of coronaviruses
Coronaviruses not only use the machinery of the human cells they infect: they modify it to achieve optimal conditions to produce viral proteins and thus spread more quickly, according to a study identifying enzymes that modify transfer RNAs as key elements for coronavirus infection.

NewsNew study demonstrates universal newborn cCMV screening leads to earlier detection and increased identification of mild hearing loss
A new retrospective cohort study examining the impact of Minnesota’s first-in-the-nation mandated universal newborn screening for congenital cytomegalovirus (cCMV) shows that universal screening significantly decreased the age at first audiology visit and increased identification of mild hearing loss in infants.

NewsEnhanced inner ear tropism of Adeno-Associated Virus (AAV) vectors via peptide display on AAV1 capsid
Researchers improving efficiacy of AAV)-mediated gene therapy for the inner ear screened and inserted short peptide motifs onto the surface of the AAV1 capsid. These engineered vectors achieved markedly higher transduction rates in inner ear hair cells and supporting cells.
