NewsWhat we know and what we need to know about Antarctic marine viruses
Antarctic marine viruses, while proven to be important players in the ecosystem, are not completely understood. In a new paper, researchers aim to fill in the gap between what is known and what is unknown, with a primary focus on RNA viruses, the influence of climate change and their implications.

NewsDiscovery of hundreds of new human gut viruses provides a new approach to studying the gut microbiome
Hundreds of new viruses living inside bacteria within our gut have been discovered in an international study. These bacteriophages could eventually be used to reshape the gut microbiome, potentially influencing gut health and the progression of various disease states.

NewsCould cardamom seeds be a potential source of antiviral treatment?
Researchers have found that cardamom seed extract, as well as its main bioactive ingredient, 1,8-cineole, can have potent antiviral effects through its ability to enhance the production of antiviral molecules known as type I interferons via nucleic acid ‘sensors’ inside cells.

NewsSafer, more effective vaccines with new mRNA vaccine technology
A new messenger ribonucleic acid (mRNA) vaccine technology could make future vaccines safer, more effective, and less burdensome for patients. The new approach uses albumin-recruiting lipid nanoparticles to deliver mRNA precisely to lymph nodes while bypassing the liver.

NewsTwo-dose recombinant shingles vaccine is effective even accounting for prior receipt of live shingles vaccine
A target trial emulation was conducted to assess the effectiveness of recombinant zoster vaccine (RZV) accounting for prior receipt of live zoster vaccine (ZVL) and immunocompetence. The results suggest individuals vaccinated with ZVL should be revaccinated with two doses of RZV.
