Gene editing has become dramatically faster and more precise thanks to CRISPR, a tool adapted from a natural bacterial defense system. Scientists now use CRISPR to change DNA in plants, animals, and humans, unlocking possibilities from drought-proof crops to potential cures for genetic diseases. By guiding molecular scissors to any gene, nearly any trait can be altered as easily as correcting a typo. However, ethical dilemmas and unpredictable effects accompany this newfound power to rewrite life.
