THE Vatican seldom approves of scientists meddling with God's creation. So the decision of the Pontifical Academy of Sciences to back oft-demonised genetically modified crops as an answer to world hunger and poverty may come as a surprise.

GM crops were heartily endorsed at a week-long seminar held by the academy in mid-May. Participants agreed that the crops offer food safety and security, better health and environmental sustainability. That verdict is not shared by the International Assessment of Agricultural Knowledge, Science and Technology for Development, a global UN-backed think tank that last year rejected GM as a solution to hunger.
