Discovering the molecular biology of allergy:
"...In mice lacking the gene for p110delta, the allergic response was reduced substantially; in normal mice that had been treated with an experimental drug inhibiting p110delta, the allergic response was stopped completely."
Obviously you can see the dollar signs. I think the more interesting point of the fundamental instrumentality of machine culture - note, the emphasis is on treating the effect, not the cause (ie, nasty stuff in our environment). The costs of treating the cause are (by definition) prohibitively high; hence, arms races (ie, fat wars) and herding behaviour (ie, diets).
