Quick! When you think of non-native species, what's your first reaction? That they're Public Enemy No. 1? According to a recent Nature journal essay, non-natives are so vilified today that a “pervasive bias” exists against non-native species, a...

It's a killer, pure and simple. But the issue is as complex as it comes. The malaria mosquito, from the genus Anopheles, infects some 350 to 500 million people a year, killing more than a million. Most are young children in sub-Saharan Africa. Female...
