NewsScientists uncover secrets of cryo-EM structures of Nipah virus polymerase complex
A new investigation into the cryo-EM structures of Nipah virus polymerase complex reveals highly varied interactions between L and P proteins among paramyxoviruses.

NewsForever chemicals influence cellular immune response to coronavirus
A new study shows that PFAS influence the cellular immune response to coronavirus and also reveals sex-specific differences as to how the immune system reacts to the virus.

NewsNew study shows obesity linked to long COVID
New research has found that people with excess weight are more likely to experience long-term neurological and mental health symptoms after COVID-19, including headache, vertigo, smell and taste disorders, sleep disturbance, and depression.

NewsPredictive AI model can help build vaccines for future versions of a virus
Researchers have created an AI tool called EVE-Vax that can predict and design viral proteins likely to emerge in the future. For SARS-CoV-2, panels of these “designer” proteins triggered similar immune responses as real-life viral proteins that emerged during the pandemic.

NewsGlobal Virus Network meeting unites Caribbean and Latin America to tackle emerging viral threats
A two-day summit focused on collaborative strategies to bolster viral surveillance, diagnostics, vaccine research, and pandemic preparedness across Latin America and the Caribbean, challenges intensified by climate change and globalization.

NewsScientists engineer antibody against flu with sticky staying power
Scientists have engineered a monoclonal antibody that can protect mice from a lethal dose of influenza A, a new study shows. The new molecule combines the specificity of a mature flu fighter with the broad binding capacity of a more general immune system defender. Source: NIAID Colorized transmission ...

NewsResearchers valuate the safety and efficacy of a smallpox vaccine for preventing mpox
Researchers explored the viability and safety of LC16m8, an attenuated vaccinia virus vaccine, to prevent monkeypox. The study evaluated the immunogenicity and safety of LC16m8 across three animal species.

NewsScientists win award for bringing breakthrough HIV treatment lenacapavir into play
Three people have been awarded the AAAS Mani L. Bhaumik Breakthrough of the Year Award for their work on the first HIV drug to offer long-lasting protection from infection — eliminating the need for people to take a daily pill.

NewsGlobal review of bird flu in cats points to risk of another pandemic
Bird flu (H5N1) is rapidly evolving into the possibility of a human pandemic, say researchers who have been documenting research on bird flu in cats and calling for urgent surveillance of cats to help avoid human-to-human transmission.

NewsViruses under the super microscope: How influenza viruses communicate with cells
Scientists have characterized a new model of influenza A infection: binding to MHC class II complexes as an alternative receptor and the associated dynamic reorganization of the cell surface.

OpinionIt’s game over for dangerous Gain of Function research
The Trump adminstration has signed an Executive Order halting federal gain of function research on microbes - but does it throw the baby out with the bathwater? Virologist Simon Wain-Hobson, Emeritus Professor with the Pasteur Institute, Paris, gives his take.

NewsBat virus evolution suggests wildlife trade sparked COVID-19 virus emergence in humans
The ancestor of the virus that causes COVID-19 left its point of origin in Western China or Northern Laos just several years before the disease first emerged in humans up to 2,700 kilometers away in Central China, suggesting the wildlife trade played a role.

NewsSilver nanoparticles produced by fungus could be used to prevent and treat COVID-19
Silver nanoparticles produced by the fungus Trichoderma reesei could become important allies in the prevention and treatment of COVID-19. Tests on hamsters showed that they not only inhibited the infection but also reduced the viral load in the lungs.

NewsLong COVID may cause long-term changes in the heart and lungs and may lead to cardiac and pulmonary diseases
Patients suffering from long COVID may exhibit persistent inflammation in the heart and lungs for up to a year following SARS-CoV-2 infection, potentially placing them at elevated risk for future cardiac and pulmonary conditions.

NewsNew CDC nPEP Guidelines should become ‘part of general medical practice’
Health experts say the updated CDC HIV Non-Occupational Post Exposure Prophylaxis (nPEP) Guidelines should be part of general medical practice, as incorporating them will reduce new HIV infections and improve public health.

NewsAntibodies that recognize lipids: A new path for HIV vaccines and autoimmune disease treatments
Scientists have used computer modeling to illustrate how a specific class of antibodies actually use lipids to recognize the HIV virus. The work highlights antibody features that could help people design better vaccines for HIV and autoimmune diseases.
