We believe what we see. We accept the fact of a hairline fracture when its track appears on the X-ray. We rest easy when the sonogram shows a living, breathing baby, complete with fingers and toes. And we fear what we cannot see—a lump, a ballooning vein, a clot, a secret growth that numbs the hand and slurs the speech. Too often, this sort of threat seems to hide in the blurred, murky shadows of a two-dimensional graphic, where our doctors must try to detect the shape of an enemy in the dark. 

Yes, we need doctors with Superman's eyes. And the quest for that kind of power is the subject of our cover story. It is a quest that has united, with a kind of contagious fervor, surgeons and radiologists and computer scientists and physicists and psychologists and many more—all of them working on a better way to see. 

Many of these men and women are graduate students, which brings us to the story behind the stories. In this issue of Endeavors, you will find several features about the work of young women and men who are helping to create new knowledge as they also learn to teach, to investigate, and to prepare for professional life. Endeavors itself would not be possible without graduate students. Chris Hammond and Mark Briggs, who wrote several stories for this issue, are master's students in journalism, and Liz Zubritsky, a recent graduate of the same program, wrote the story on page 6. 

This is also the last issue to appear during the administration of Tom Meyer, vice provost of graduate studies and research, who is returning to the Department of Chemistry. Tom, with Linda Dykstra, dean of the graduate school, has campaigned tirelessly to increase support for graduate students and graduate education at Carolina. He has been a steadfast ally and adviser for all of us here at Endeavors, and we wish him the best.
