Trump Executive Order Restricts ‘Gain of Function’ Research on Pathogens

President Trump signed an executive order on Monday evening to further restrict experiments on pathogens and toxins that could make them more harmful.

For over a decade, scientists have debated the risks and benefits of so-called “gain of function” research. They’ve long tinkered with viruses and bacteria to endow them with new functions like producing insulin for people with diabetes. Some researchers have modified bird flu viruses in order to figure out which mutations might be crucial for producing pandemic strains that could spread among people.
