Love the article. It says ABSOLUTELY NOTHING.

It's the aliens, man! They mess with your hair, then they get into your brain!
I loved this comment under the story

The article has a link to the source article in the U.K., where you find a)you are not a subscriber and so b)only by paying the U.S. equivalent of 15 British Pounds can you download the full scholastic article (as a PDF) - where maybe there are more details.
It will likely be some time before any of the additional details are reported in “free” media content.
