Here’s your happythought for the day:

Chlorovirus ATCV-1 is part of the human oropharyngeal virome and is associated with changes in cognitive functions in humans and mice

Short form: a virus known for infecting algae is now known to be able to infect humans and mice. The main effect of this infection seems to be that it makes you dumber. Not drastically, but measurably. I’m not a geneticist or biologist or biochemist or even a homeopathic practitioner, but the article seems to suggest that the virus actually tinkers on a genetic level.
