Circular single-stranded DNA viruses represent a diverse group of pathogens that possess a covalently closed, circular single-stranded DNA genome. Their small genomes belie a sophisticated replication ...

Researchers updated the global catalogue of human-infective RNA viruses to 239 ICTV-recognised species, incorporating ...

Viruses have limited genetic material -- and few proteins -- so all the pieces must work extra hard. Zika is a great example; the virus only produces 10 proteins. Now researchers have shown how the ...

Researchers studying strains of a lethal canine virus and a related human virus have determined why the canine virus was able to spread so quickly from cats to dogs, and then from sick dogs to healthy ...

There is an ongoing debate as to whether or not viruses are considered to be a life form. The question remains unanswered as the identity of viruses as a living form is dependent on arbitrary measures ...

A new family of enzymes enables precise cuts in single-stranded DNA, offering powerful new tools for genetic engineering and expanding possibilities in biotechnology. (Nanowerk News) A few years ago, ...
