A new software algorithm developed at Caltech enables researchers to easily search for viruses in RNA sequence data, enabling scientists to detect viruses in samples and study how they impact ...

Viruses are masters at taking over our cells: They disable our defenses and hijack the cellular machinery in order to multiply successfully. For example, the herpes simplex virus 1, which causes ...

Scientists in Switzerland have cracked open a century-old viral mystery by decoding the genome of the 1918 influenza virus from a preserved Zurich patient. This ancient RNA revealed that the virus had ...

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 ...

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 ...

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 ...

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 ...

Scientists discover new viruses every year. A catalogue of the riskiest ones could help us spot the next pandemic before it ...

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 ...

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 ...
