Fruit Flies: The Latest Buzz In Gene Therapy

Geneticists dream of a day when they can repair defective human genes to wipe out diseases. That goal is decades off, but research on insects offers intriguing leads. This summer, scientists at San Diego State University restored the gift of flight to genetically defective fruit flies by injecting new genes into fly embryos. Doctors are taking note because defects in a similar human gene, which codes for the protein myosin, cause heart disease.
