Singularity! Scientists Developing Anti-Trauma Pill

Some doctors have an even more ambitious goal: trying to cure PTSD. They are deliberately triggering very old bad memories and then giving the pill to deep-six them.

The first study to test this approach on 19 longtime PTSD sufferers has provided early encouraging results, Canadian and Harvard University researchers report.

"We figure we need to test about 10 more people until we've got solid evidence." said Alain Brunet, a psychologist at McGill University in Montreal who is leading the study.
