RT Journal Article SR Electronic T1 Sensitive and controversial ethical issues subject of groundbreaking Toronto exhibit JF Canadian Medical Association Journal JO CMAJ FD Canadian Medical Association SP 1483 OP 1486 VO 155 IS 10 A1 Kezwer, G. A1 Kramer, D. YR 1996 UL http://www.cmaj.ca/content/155/10/1483.abstract AB Medical research and practice have always posed many ethical dilemmas for scientists and physicians, but technologic advances mean that the questions are becoming even more difficult. That is why an exhibit, A Question of Truth, that is being prepared at Toronto's Ontario Science Centre is so timely. It examines the biases and political climates in which science operates, as well as the relative subjectivity of truth, knowledge and reality.
