I'm all for a magazine which, as you described, is "designed to give the average person an overview of the latest scientific research, without expecting pior knowledge in the field". But it could be done without sensationalising everything quite as much as New Scientist feels the need to do.

Frinstance, New Scientis starts an article on the fairly prosaic subject of random matrix theory with this paragraph:

"SUPPOSE we had a theory that could explain everything. Not just atoms and quarks but aspects of our everyday lives too. Sound impossible? Perhaps not."
