Looks to me like a bot generated the article, given its weird capitalization and inconsitent internal references. Here is the press release from Columbia University:

I also felt that the Pro Tribune version of the articles was bot-generated because of the capitalization: "that helps Enzymes known as", "changing signs with Electronics", "in response to a Particular signal". They occur at roughly the same column position, so it looks like the result of a fixed-line-length copy&paste into a word processor that auto-capitalized each new line. Horrible editing for them to not notice this.
