• That, as a new study suggests, there is no single gay gene, but rather multiple different originals for non-heterosexual sexual orientations and behaviours, makes intuitive sense to me. The Washington Post has one take.


• Atlas Obscura looks at the history behind the stone walls of New England.
  
• Justin Fox at Bloomberg examines how the once-commanding lead in incomes of the middle class of the United States over the middle classes of other countries is starting to fade.


• CityLab looks at how, too often by design, beaches in the United States are inaccessible to mass transit. (Toronto is lucky.)


• La Presse shares a proposal by Radio-Canada to move away from a media model of competing with other outlets towards one based on collaboration.
