Shame on this article. We should be researching everything within moral limits. Everything. Research all of it so hard that there's no long any debate about whether this point or that has any standing because it's so well understood that we can just fucking move on. Regardless of the topic, if we aren't sure if it's of value - we learn as much as we can until we can allow ourselves as a species to move on. That's the only way to prove any point in the realm of curiosity that satisfies me. Articles that argue the validity of investgating an unknown for any reason other than "it would cause significant harm" don't hold any weight and should be disregarded as either being based in fear, self interest, or simple ignorance.
