In simple terms: a virus is a tiny package of genetic instructions with a delivery system. Outside a cell it is metabolically inert. Once inside a susceptible cell, it redirects the cell's machinery ...

Viruses evolve quickly mainly because of how they replicate and mutate. Unlike cells, viruses must invade a host cell and ...

Newcastle disease virus, an avian paramyxovirus that infects more than 250 animal species ranging from poultry to mammals, builds conspicuous cytoplasmic inclusion bodies during infection. These ...

A new review maps the orthohantavirus life cycle for chemotherapeutic intervention, evaluating entry inhibitors, polymerase ...

A research team at Ruhr University Bochum, Germany, has identified a previously unknown cellular mechanism crucial to the replication of coronaviruses: c-Jun N-terminal kinase (JNK) is activated ...

In a new study, published in Cell, researchers describe a newfound mechanism for creating proteins in a giant DNA virus, comparable to a mechanism in eukaryotic cells. The finding challenges the dogma ...

Air pollution from cruise ships could be damaging the health of people living in port cities by increasing inflammation and susceptibility to viruses such as the common cold and COVID-19. New research ...

For decades, the arrival of the monsoon season across India and tropical nations has brought an overwhelming wave of dengue ...

Plant DNA viruses — including double-stranded DNA viruses such as caulimoviruses and single-stranded DNA viruses such as ...

Some viral realms infect only specific groups of organisms, which suggests they arose after certain branches of life had already evolved, rather than dating all the way back to LUCA. For instance, ...
