New Scientist is not a genuine science publication.

It is science-oriented tabloid with a definite political agenda.

Real science and math publications are very hard to understand unless you are trained in that field. They also have very limited circulation and cost more to print that they can ever bring in.

By simplifying the product so the average high schooll student can roughly understand what is being said enables several things to happen. Firstly, the publisher can sell millions of copies and make lots of money. Secondly, he can push his political point of view.
