When a virus enters a cell, its top priority is to replicate its genome rapidly, creating new viruses to infect elsewhere. The host has the opposite priority: to destroy the virus, ideally before it ...

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 ...

How did viruses evolve? Are they a streamlined form of something that existed long ago, or an ultimate culmination of smaller genetic elements joined together? Aa Aa Aa The evolutionary history of ...

Bacteriophages deploy streamlined yet robust strategies to replicate their DNA within host cells. Replication typically initiates at defined viral origins recognised by phage-encoded initiator ...

Hidden mechanisms in extracellular DNA spotted by researchers at Aarhus University enable dormant viruses to become ...

Add Yahoo as a preferred source to see more of our stories on Google. A newly found giant virus from Lake Ushiku shows unusual spikes and a distinct way of disrupting a host nucleus, fueling debates ...

To better understand BKPyV replication and ways to prevent it, researchers in the UAB Department of Microbiology have published a single-cell analysis of BKPyV infection in primary kidney cells. Their ...

A newly developed, analytically validated automated qPCR assay for Torque teno virus DNA achieved a limit of detection of ...

Single-cell analysis helps uncover how the BK virus replicates, opening the door to new drug targets. BK polyomavirus (BKPyV) is a major cause of kidney transplant failure. Without a complete ...

Researchers found that enzymes released when bacteriophages burst bacterial cells can continue producing DNA in biofilms, ...

Learn how ancient DNA from human remains provided the first direct evidence that a common childhood virus has been part of the human genome since the Iron Age. Human herpesvirus 6 is nearly universal ...
