Have you ever wondered what is responsible
for unspeakable stupidity? Well some US
scientists might have the answer, having
discovered an algae virus which some call
“stupid virus” that infects human brains and
makes people more stupid. The surprise virus
discovery was made by a team at the Johns
Hopkins Medical School and the University of
Nebraska while undertaking a study into
throat micro-organisms.
90 people participated in the study and 40
tested positive for the stupid virus. It was
then proved that those who had tested
positive performed worse on tests that were
designed to measure visual processing and
attention spans.
Although human bodies contain a multitude of
bacteria and fungi, the study has shown that
specific micro-organisms can have a negative
effect on intelligent processing.
The study was led by Dr Robert Yolken, a
virologist, who said:
‘This is a striking example showing that the
“innocuous” microorganisms we carry can
affect behaviour and cognition. Many
physiological differences between person A
and person B are encoded in the set of genes
each inherits from parents, yet some of these
differences are fueled by the various
microorganisms we harbour and the way they
interact with our genes.’
