Transplants, Cooley told an American College of Cardiology meeting in Los Angeles, have produced evidence that the development of a successful artificial heart "may actually be easier than we had previously believed." The explanation: nature has provided the mammalian (including the human) heart with an elaborate fail-safe system of dual controls, one through the nervous system and another through hormonal channels. Early researchers on artificial hearts were overwhelmed by the difficulties of trying to duplicate these enormously complex natural systems. This, said Cooley, is not necessary...

Quality control is becoming an increasingly big headache on Mondays and Fridays, when high absenteeism forces management to rely heavily on backup...
