Scientists Discover a Virus That Changes the Brain to 'Makes Humans More Stupid'

concertina226 writes: Scientists at the Johns Hopkins Medical School and the University of Nebraska have discovered an algae virus that makes us more stupid by infecting our brains.

The researchers were conducting a completely unrelated study into throat microbes when they realised that DNA in the throats of healthy people matched the DNA of a chlorovirus virus known as ATCV-1.

ATCV-1 is a virus that infects the green algae found in freshwater lakes and ponds. It had previously been thought to be non-infectious to humans, but the scientists found that it actually affects cognitive functions in the brain by shortening attention span and causing a decrease in spatial awareness.

For the first time ever, the researchers proved that microorganisms have the ability to trigger delicate physiological changes to the human body, without launching a full-blown attack on the human immune system.
