British biotech firm awaiting FDA approval to release bugs in the Florida KeysChange.org petition gets more than 130,000 signatures to stop experiment Millions of genetically modified mosquitoes could be released in the Florida Keys if British researchers win approval to use the bugs against two extremely painful viral diseases.
