willmc writes "I just caught an article on CNN.com talking about a genetically revised moth that will be tested in a controlled outdoor environment this summer, and is expected to be released into the wild in the not-too-distant future. The insect is a pink bollworm moth that is a pest to cotton fields. The change that they're testing first is the addition of a luminosity gene from a jellyfish, and later an alteration that will make them sterile so they can mate with non-altered moths and create sterile offspring, thus reducing or eliminating the moths' population. This sort of thing tends to make me very nervous..." Don't worry. We can always release killer bats to get the moths, and giant carnivorous hedgehogs to kill the bats.
