gain-of-function

Added biological ability

Gain-of-function describes research that intentionally enhances a pathogen's capabilities—making a virus more transmissible, virulent, or able to infect new hosts.

The term became prominent during debates about laboratory safety and the origins of COVID-19: gain-of-function experiments on coronaviruses.

Such research aims to anticipate natural mutations but carries obvious biosecurity risks.
