A group of scientists now claim that the longest river in the world is the Amazon, not the Nile.

(Usually the Amazon is regarded as the world’s largest river by volume, but has always come second in length to the River Nile. But now scientists in Brazil claim to have discovered a new source for the Amazon, which lies in the south of Peru and not the north of the country as had been thought for many years. While the exact location has yet to be confirmed from two choices, scientists say either would make the river the longest in the world. That means I will have to rewrite my pages on comparatives and superlatives.)
