I wrote the following article three years ago and it was published online by Spiral Nature Magazine. Their website has stopped working for some time and, since they published nothing for more than a couple of years, I'm thinking they must've closed up shop. Because of this, anything posted there is in danger of being lost, sadly. Not just my stuff would be lost as a result, but many other articles that have helped me over time. Unfortunately, I cannot salvage anything that was not written by me...
Here is the article itself and I will try to edit it to make sense because it's being copied from a pdf file that was formatted much differently than a standard word doc. The article itself was edited by a staff member of Spiral Nature - Steve, if I can remember correctly.
