And Korean stem cell research, and the misinterpretation of the hockey stick phenomenon, and the fact that the whole system is set up to encourage "cutting edge" fraud...
The "system" is set up to advance science. But any system can be abused. Note how the religious community was abused by folks like Jim Jones. But pointing that out is not an argument for eliminating religion because Jones was the exception, not the rule.
The Korean stem cell issue and the others you list are also exceptions, and should not be used to smear all of science, but only to correct it's flaws.
