Real science: Almost half the population may be infected with a mysterious virus that makes people stupid

Fascinatingly, this discovery makes tremendous sense. Have you ever looked at the world around you and wondered why so many people seem intellectually challenged? Now we know that a virus really can alter the function and expression of your brain cells.

Scientists at Johns Hopkins Medical School have identified a mysterious virus that literally makes people stupid, and it has so far been found in about 45% of the people tested. The discovery of the "stupid" virus, normally found in algae, was revealed at the Proceedings of the National Academy of Sciences.
