Now it seems a lot easier to determine what proteins the broken genes should be making and replace them instead.

Soon engineers will perfect the tools that allow surgeons to simulate an operation realistically--down to the resistance of skin against scalpel...

In up to 20% of cases, doctors operate only to find a perfectly healthy appendix. Now a study shows that examining the abdomen with ultrasound or a CAT scan is 94% accurate in diagnosing whether a sick child does or does not require surgery.
