People who contract COVID-19 but never develop symptoms — the so-called super dodgers — may have a genetic ace up their sleeve. They’re more than twice as likely as those who become symptomatic to ...

A rare genetic mutation appears to make people basically invulnerable to viruses – and it could potentially be harnessed as a therapy. Researchers have now shown this surprising viral protection can ...

New research shows how small shifts in the molecular makeup of a virus can profoundly alter its fate. These shifts could turn a deadly pathogen into a harmless bug or supercharge a relatively benign ...
