So, which respiratory virus invaded your cells? Several types of viruses could be the culprit: respiratory syncytial virus ...

This is SARS-CoV-2, the virus that causes COVID-19. It's a type of RNA virus, some of which mutate practically every time they replicate. SARS-CoV-2 is actually one of the rare RNA viruses that ...

Viruses, then, may have existed before bacteria, archaea, or eukaryotes (Figure 4; Prangishvili et al. 2006). Most biologists now agree that the very first replicating molecules consisted of RNA ...

In fact, a new study by the Tuschl laboratory introduces a proof-of-concept for a novel class of antivirals that would target a type of enzyme essential not just to SARS, but also many RNA viruses, ...

Ribonucleic acid (RNA) is a linear molecule composed of four types of smaller molecules called ribonucleotide bases: adenine (A), cytosine (C), guanine (G), and uracil (U). RNA is often compared ...

Weizmann Institute researchers have developed a new way to track the culprit – giant viruses – and identify their traces in specific types of tiny algae that they attack.

To fight the virus that causes influenza, one of the avenues being explored by scientists is the development of drugs capable of destabilising its genome, made up of eight RNA 1 molecules. But the ...
