How to Disable "What's Hot" on your timeline

There has been a recent wave of racist posts about Baltimore, including one linking to an ugly article and saying, in the post, that it is "open season on [highly offensive term for African-Americans]".  Maybe Google has a team to manually review these threats and call the police, but, in the mean time, Google+ algorithms have been putting these posts on my feed repeatedly because they are "Hot on Google+"  I thought I might have to leave this social network.

Turns out that you can disable "What's Hot" on your timeline entirely.  I've attached a cropped screen capture.  Full instructions are at https://support.google.com/plus/answer/1686118

When the bacterium E. coli is cultured in a lab, researchers add citrate to the flasks as a chelating agent.  It's not there to feed the bacteria, it's just used to bind metal ions in the solution.  But in one lab, after 30,000 generations, the bacteria mutated to be able to eat it.  Subsequent mutations improved their utilization of this new food source through the process of natural selection.
