Any new medical school faces challenges, not the least of which is collecting enough dead bodies to train its students. But thanks to the Internet and a down economy, that task is getting easier. For all the advances in medical training, there's still no substitute for the human cadaver. And with Quinnipiac University's new medical school, the Frank H. Netter MD School of Medicine, scheduled to begin classes in the fall, educators there are seeking donations. "We need roughly about 40 to 50 bodies a year," said Jim Casso, director of Quinnipiac University's human anatomy laboratory.
