Recent research reveals that nuclear speckles play a key role in modifying viral messenger RNAs and in their transport out of ...

This story is part of a larger series on viroids and virusoids, small infectious RNAs. It is also the sixth installment in a series on hepatitis D virus, a virusoid-like pathogen that causes serious ...

In a twist on the question, 'Which came first, the chicken or the egg?', scientists have long faced a similar question about how human adenovirus replicates: 'Which comes first, assembly of the viral ...

During viral reproduction, the influenza polymerase (top left, in blue) scans along the ribonucleoprotein helix to produce messenger RNA. Credit: Science Like a camera-shy teenager, influenza’s ...

Researchers have found a way to block one strain of the influenza virus from accessing a human protein it needs to replicate in cells. The discovery could lead to highly effective ways to treat the ...

Understanding the differences between bacteria and viruses is crucial for recognizing how these microorganisms impact our ...

A study published in PNAS Microbiology found that enveloped viruses harbor greater cross-species transmissibility and are more likely to cause zoonotic infections than nonenveloped viruses. The ...

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 ...
