Researchers found that Zika virus induces cells to create connections, called tunneling nanotubes, that may enable the virus to replicate and spread from mother to fetus. UNIVERSITY PARK, Pa. — In ...

Viruses are tiny agents that can infect a variety of living organisms, including bacteria, plants, and animals. Like other viruses, the dengue virus is a microscopic structure that can only replicate ...

Human norovirus, a positive-strand RNA virus that is the leading cause of viral gastroenteritis accounting for an estimated 685 million cases and approximately 212,000 deaths globally per year, has no ...

A chemical modification in the HIV-1 RNA genome whose function has been a matter of scientific debate is now confirmed to be key to the virus's ability to survive and thrive after infecting host cells ...

If your holiday season activities include a luxury cruise or feasting on raw oysters, then beware: Norovirus, a gastrointestinal RNA virus that can cause nausea and diarrhea, could be an unwelcome ...

Viruses are entities that have to infect other cells in order to replicate. They may have genomes that are made of DNA or RNA. We are still discovering new types of RNA viruses, as shown in two new ...

Structure of the influenza virus replication complex, comprising two viral polymerases (dark and light colours) in interaction with human ANP32 (purple). In recent years, public health measures, ...

Prevention remains critical; but once symptoms appear, treatment options are extremely limited. Because rabies hides behind a complex molecular shield, it is nearly impossible to fight. “For more than ...

For decades, biology textbooks have drawn a firm line: viruses are not alive. They lack the machinery to reproduce on their own, they carry no metabolism, and they depend entirely on host cells to ...
