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 ...

That study reported that the RNA virus called lymphocytic choriomeningitis virus (LCMV) had somehow integrated into the mouse genome -- surprising because with the exception of retroviruses like HIV, ...

Research on the genome of the virus that causes severe acute respiratory syndrome (SARS) has revealed an unusual molecular structure that looks like a promising target for antiviral drugs. A team of ...

“Our analyses show that the historical [human Rhinovirus] A genome represents an extinct lineage closely related to HRV A19 ...

161,979 new RNA viruses have been discovered using a machine learning tool that researchers believe will vastly improve the mapping of life on Earth and could aid in the identification of many ...

The world is absolutely teeming with viruses. The infectious agents are widely considered the most abundant biological entity on Earth. But a full understanding of viruses and the roles they play in ...

A new study by researchers at Bar-Ilan University has uncovered that certain ocean viruses—specifically RNA viruses—may disrupt how carbon and nutrients are recycled in the ocean, potentially altering ...

Researchers at the Federal University of São Paulo (UNIFESP) in Brazil have discovered that SARS-CoV-2, the virus that causes COVID-19, uses a sophisticated tactic to evade the human body’s defense ...

A new role has been uncovered for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part ...

Have you ever wondered why you have to get a flu shot every year, but some vaccines are one-and-done? It all has to do with how and how fast viruses evolve - and that depends on mutation rates.
