Turds tell tales, and UC San Diego is listening.

As the beginning of the school year nears, the university is preparing to ramp up its testing of sewage for the coronavirus.

Along those lines, UCSD on Saturday sent out its first campus-wide email alert about the detection of the virus in sewage from one of its seven colleges.
