NewsStudy confirms effectiveness of medicinal plant against SARS-CoV-2 virus
A study has revealed that galloylquinic acids extracted from the leaves of Copaifera lucens Dwyer, a tree endemic to Brazil primarily found in the Atlantic Forest, have a multi-targeted effect against SARS-CoV-2, the virus that causes COVID-19.

NewsTeam discovers gene pattern that could help doctors identify Ebola faster and more accurately
Researchers have made an important discovery that could help doctors tell Ebola apart from other infections more quickly. The overlap of response by Ebola and other pathogens had made it difficult to find markers that are truly unique to Ebola.

NewsYour nose is a battlefield
Scientists have discovered that FluMist can trigger an immune response directly in nasal tissue in adults. The vaccine trains immune cells in the upper nasal passages to recognize and fight influenza virus infection. This immune response stays in the upper airways and can’t be detected via blood samples.

NewsHow does oligochitosan induce plant resistance against potato virus Y?
Plant immune inducers are crucial tools for the green management of crop diseases. As an environmentally friendly biological inducer, oligochitosan (COS) can activate plant defense mechanisms to resist pathogens such as fungi, bacteria, and viruses.

NewsNew study shows antibodies need a strong core — not just grip — to fight SARS-CoV-2
Researchers used advanced computer simulations to investigate how antibody–virus complexes respond to mechanical forces across multiple SARS-CoV-2 variants, including the original 2019 strain and Omicron subvariants BA.4 and JN.1.

NewsVaccine strategy induces broadly neutralising HIV antibodies
Researchers have developed a new vaccine strategy that has generated antibodies capable of neutralising highly divergent HIV variants. The study provides new insights into how the immune system can be guided towards a particularly protected part of the virus.

NewsResearch gaps and regional disparities revealed in global Lassa virus research landscape
A comprehensive bibliometric analysis spanning 55 years of Lassa virus (LASV) research has uncovered significant disparities in scientific output between high-income and endemic countries, while revealing a persistent shortage of studies addressing environmental factors influencing viral spread.

NewsNew study suggests seasonal flu vaccines may reduce severity of H5N1 bird flu infections
Researchers have found that seasonal influenza vaccines in routine global use may significantly reduce the risk of death from H5N1 infection. The findings that readily available tools may offer protection while the world races to develop more targeted solutions.

NewsHow the immune system battles lifelong viral infections acquired at birth
Millions of people worldwide carry viral infections they acquired at birth, often for life. For a long time it was assumed that the immune system hardly fights these pathogens. Researchers show that the body’s defenses do indeed act against the virus.

NewsSelf‑replicating circular RNA persists in extreme environments: Insights from hot spring microbiomes
Researchers who previously identified a highly unusual RNA virus in a high-temperature hot spring ecosystem searched for distinct types of self-replicating RNAs in a similar extreme environment, and a novel circular RNA replicon was identified within the microbial community inhabiting the hot spring.

NewsNew study suggests reduced newborn hepatitis B vaccination coverage may increase infant infections
Researchers found that lower vaccination coverage among infants born to unscreened mothers was associated with a substantial increase in HBV infections.

NewsGlobal Virus Network statement on H5N1 vaccine developments
The new vaccine momentum reflects the growing urgency of avian influenza (H5N1) threat and reinforces the need for coordinated global preparedness.

NewsResearchers discover new mosquito-specific viruses
A new study looked at mosquitoes’ immune response to discover many more insect viruses. Researchers hope to someday use the mosquitoes’ own immune system to battle some of the most pervasive and antagonistic human viruses.

NewsNew cellular target prevents hepatitis E infection
To replicate, a virus must first enter a host cell. In a recent study, the researchers specifically investigated host cell processes required for successful HEV infection. In doing so, they identified the enzyme PIKfyve as a crucial factor for viral entry.

NewsImmune cells in the nose slow influenza virus
Memory cells in the nose slow the influenza virus as soon as it enters the body. They reduce viral levels and may help protect against more severe illness, according to a study that may help guide the development of better influenza vaccines.

NewsAssociation of changes in portal insulin with immunometabolism during and after hepatitis C virus infection
A new study aims to investigate the relationship between insulin, the gut-liver axis, and immunometabolic changes in patients with hepatitis C virus. Lower portal insulin during HCVi is associated with changes consistent with altered pancreatic insulin secretion and decreased hepatic insulin extraction.

NewsHow AI can help us count the ‘good’ viruses used in biopharmaceuticals
Researchers have developed a new methodology that uses artificial intelligence (AI) tools to identify and count target viruses more efficiently than previous techniques. The new approach can be used in applications such as pharmaceutical biomanufacturing.

NewsResearchers deploy phage therapy in new frontier against antimicrobial resistant infectious diseases
A revelatory treatment for patients with life-threatening infectious diseases is being pioneered in Melbourne. VICPhage, a clinical partnership between The Alfred and Monash, is one of the first in Australia to offer end-to-end capacity in phage therapy to treat some of the most challenging infections.

NewsStudy of influenza D in human cells and tissue hints at spillover potential
The influenza D virus that researchers say has been flying under the radar since its detection in animals in 2011 can vigorously make copies of itself in human cells and lung tissue samples, a new study shows.

NewsResearchers develop promising new vaccine against H5N1 bird flu
Researchers have developed a vaccine approach that shows promise in protecting against highly pathogenic bird flu, demonstrating strong efficacy in both mice and cattle. In 2024, the virus spread to dairy cattle and subsequently caused illness in about 70 farm workers with close contact to infected animals.
