Scientists discover virus that causes human stupidity
We’ve often wondered what exactly is responsible for unspeakable stupidity.
US scientists might have the answer, having discovered a virus that infects human brains and makes people more stupid.
The algae virus has never before been observed in healthy people and was discovered to affect cognitive functions such as visual processing and spatial awareness.
The surprise discovery was made by a team at Johns Hopkins Medical School and the University of Nebraska when undertaking a separate study into throat microbes
A large group of scientists from both Johns Hopkins University and the University of Nebraska examined microorganisms that populate our "mucosal surfaces."
A surprise discovery was that the ATCV-1 virus -- which comes from algae -- seemed to affect human cognition. Previously, it had been thought that humans weren't prone to being infected by this virus. However, in taking throat swabs from 92 people, the researchers found 40 of them had the virus.
The research report says: "The presence of ATCV-1 DNA was not associated with demographic variables but was associated with a modest but statistically significant decrease in the performance on cognitive assessments of visual processing and visual motor speed." The decrease was around 10 percent.
The scientists tested this result by injecting mice with the same virus. They say the results were similar.
