Once again, engineers are looking to nature and to children's games to solve complex problems, the New Scientist reports. In the quest to design a small, single-bladed helicopter that doesn´t struggle to simply stay in the air, a team at the University of Maryland in the United States have discovered that seeds from trees such as the maple have an ingenious single blade structure that allows them to drift long distances and to fall safely to the ground, without the need for an engine. Most kids already knows this, of course!.
