71.   With record speed, scientists have found a new gene that, when mutated, causes breast cancer.

72.   A difficulty in this therapy is making sure the new genes are delivered to the affected organ or cells and getting them inside the cells to do their jobs.

73.   A report on the new gene map will be published Friday in the journal Science.

74.   And if so, why not plug new genes into an organism in a different order and get something entirely new?

75.   But because the new gene causes only deafness when mutated, it will give researchers a less cluttered look at the physiology of the condition.

76.   But whether anyone will ever get a new gene to cure their lactose intolerance is debatable.

77.   Experts said the new gene map eventually will enable researchers to more effectively detect and treat syphilis.

78.   Gelsinger was enrolled in an experiment designed to test whether new genes could correct an inherited liver condition caused by a genetic flaw.

79.   He was enrolled in an experiment designed to test if such disorders can be corrected with new genes.

80.   Injecting new genes into aging muscles can restore youthful vigor and strength, according to a laboratory study of mice.
