In 2005, researcher Woo-suk Hwang reported that he had made immortal stem cells from human patients. His research was hailed as a breakthrough for people affected by degenerative diseases, because stem cells may be used to repair a person's own damaged tissues. Hwang published his results in a peer-reviewed journal. In 2006, the journal retracted his paper after other scientists discovered that Hwang's group had faked their data. Does the incident show that results of scientific studies cannot be trusted? Or does it confirm the usefulness of a scientific approach, because other scientists discovered and exposed the fraud?
 
  What will be an ideal response?

Answer to Question 1

It is unfortunate that the respectable journal did not catch any experimental fraud; however, this is an example of facts change.. The process of science did work, and when the results could not be confirmed the article was retracted. It is important to hold scientists accountable for their work, and this scientist was held accountable and lost his research privileges. As in all professions, just because one person is unethical it is not fair to judge the work of everyone in that profession based on one person's actions.

Answer to Question 2

True
