Should scientists 'play God'?

A US biologist has created life in a pioneering laboratory experiment - but do you think scientists should be playing God?
Dr Craig Venter has made a significant breakthrough in genetic engineering, successfully creating a synthetic cell. This important step could lead the way to more advancements, with future developments being used for medical and environmental purposes.

But with many worried the same technology could be used to create biological weapons, do you think scientists should be allowed to 'play God'?
