I tried to find another source and they all come back to the new scientist article. I understand making a buck, but it’s too bad that they don’t allow access to articles like this after a few months since it is from July. 95% or more of those who might be interested in this will never read it. That is a 95% reduction in needed exposure for this author and his work. It hinders rather than helps his career overall. It is stepping over a dollar to pick up a dime in the long run.
The original paper is on ScienceDirect, but I couldn’t load it on this machine. I’ll try from elsewhere later.
