Three pioneering technologies have forever altered how researchers do their work and promise to revolutionize medicine, from correcting genetic disorders to treating degenerative brain diseases.
Investigations have led to the withdrawal of a study backing ivermectin to treat COVID-19. But that’s not the last time we’ll hear about this controversial drug.
