On Wednesday, they gathered at the Center for Genetics and Society in Berkeley to express their concerns that the new research lab would be a poorly regulated entity with ties to unknown energy companies, that the work there would expose employees to dangerous microbes and, if successful, ultimately rob undeveloped nations of their croplands.

"This is a wild, wild, dangerous world," said Becky McClain, a onetime molecular biologist at a Pfizer lab in Connecticut who claimed that she had been sickened by a genetically engineered virus and was fired for speaking out about it.

"We can't afford to leave it to the corporations to self-regulate," said McClain, who won a $1.37 million lawsuit against Pfizer as a whistle-blower.
