Researchers at the University of Würzburg have unveiled a new tool for analyzing RNA molecules. It visualizes their structures as interactive maps and could help to improve our understanding of ...

A new global dataset of 239 human-infective RNA viruses shows how animal hosts, vector transmission, surveillance gaps, and viral traits shape the path from spillover to epidemic threat. Study: A ...

Scientists have discovered a previously unknown virus in farmed Pacific oysters during a mass die-off in B.C., Canada. The discovery serves as a reminder that growers should exercise caution when ...

A new study has explored the RNA-binding mechanisms of the antiviral protein TRIM25. TRIM25 (green, left) finds its way to the same locations in the cell where a virus (red, middle) replicates. The ...

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 ...

Mammalian immunity has long been thought to rely solely on proteins and specialized immune cells. However, a newly proposed concept—RNA immunity—is reshaping this perspective. In a recent publication ...

Using genomics, evolutionary biologists test several hypotheses on the origin of viruses. New evidence suggests they may have emerged more times than previously thought. Corroborating the virus-first ...

Ask a friend what DNA is and, chances are, they have a general idea. Seventy years after scientists discovered the two-stranded helix, DNA (deoxyribonucleic acid) is widely understood as the keeper of ...

The innate immune system is the body's first line of defence against pathogens like bacteria or viruses. TRIM25 is a protein that is important in the innate immune response against RNA viruses, such ...
