Fake academic papers are on the rise: Why they're a danger and how to stop them

In the 1800s, British colonists in India set about trying to reduce the cobra population, which was making life and trade very difficult in Delhi. They began to pay a bounty for dead cobras. The strategy very quickly resulted ...
