Popular Science News – the invention of the insecticide soaked bed net saved a million people from death from malaria. Unfortunately, this was relatively short-lived. It seems that the population of mosquitoes that fed at night dropped because they were missing out on food and they were then replaced by mosquitoes that fed earlier in the evening, before their victims went to the safety of their insecticide soaked beds.

Antibiotics kill all but the strongest bacteria which then find that they are the only bacteria around and so have very favourable breeding grounds and on top of that they are immune to many of the cheap antibiotics in common usage.
