The stability of ribonucleoprotein complexes of SARS-CoV-2 nucleocapsid proteins differs among variants of concern and the viral evolution of nucleocapsid protein can be understood in the framework of ...

Biologists mapping the human body have long assumed that every major kind of microscopic life inside us already had a place ...

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 ...

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 ...

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 preserved lung of an 18-year-old Swiss man has been used to create the full genome of the 1918 "Spanish flu," the first complete influenza A genome with a precise date from Europe. It offers new ...

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 ...

Delving deep into bat habitats, scientists uncover how coronaviruses evolve, migrate, and cross-species, shedding light on pandemic origins and future risks. Study: Origin and cross-species ...
