This amazing fruit fly evolved to have pictures of ants on its wings
This is unbelievable, but the fruit fly G tridens has somehow evolved to have what looks like pictures of ants on its wings. Seriously, its transparent wings have an ant design on them complete with â€œsix legs, two antennae, a head, thorax and tapered abdomen.â€ Itâ€™s natureâ€™s evolutionary art painted on a flyâ€™s wings. Recently spotted by the New York Times, the fruit fly is just incredible. Other fl

BBC NEWS | Science/Nature | Care needed with carbon offsets
By Jonathan Amos Science reporter, BBC News, San Francisco Planting forests to combat global warming may be a waste of time, especially if those trees are at high latitudes, new research suggests. Scientists say the benefits that come from trees reducing atmospheric carbon dioxide can be outweighed by their capacity to trap heat near the ground. Computer modelling indicates that trees only really
