"A false vacuum, is a state or condition that does not have the lowest energy. the false vacuum state can be one of perfect symmetry, perhaps at a given instant so this symmetry breaks when we descend to a state of lower energy. a state of false vacuum is inherently unstable, and inevitably a transition is made to a true vacuum, which has lower energy."
In the current issue of Scientific American, Hellen Wallace, the director of GeneWatch UK, writes that there are a number of issues that should be addressed before any GM insects are released including “adverse effects associated with the flow of genes into the wild population; the interactions of the GM insect with target and nontarget organisms; the impact on agricultural management practices and on management measures to control insects that are vectors for diseases; and a variety of potential effects on human health.” Among the human health risks are allergies and irritation, immune malfunction, as well as the potential for other viruses to become more potent and cause additional health risks for exposed humans.
