Well, it has and it hasn't.
For example tiger stripes don't have anything to do with the NOTCH signalling pathway, and the awesomeness of the x-inactivation in tortoise shell cats also has nothing to do with tiger stripes.
Rather, the Hox genes seem quite tied up with this. The Hox genes are nothing new, they were well characterised when I was doing undergrad genetics in 2006.
This article doesn't directly answer th question of tiger stripes but is trying to tie turing's old paper, which focused on tiger stripes as an example, with new research.
Interestingly it seems like this is all just reaearch which has been pooled together with the particular aim of celebrating turing's 100th last year (see [1]) and little of the research is intrinsically ground breaking or unknown to science, but almost done with the express purpose of celebrating Turing.
By the by, did anyone think that the textile seashell pictured in the article looked like some of the shapes created in iterations of the game of life?
Tiger stripes are an example of biological patterning, as is the Notch pathway impact on neural tissue development and also the fur characteristics in other animals. Barr Bodies, Notch, trisomy, all have major impacts on pattern production.
It's meant to be an interest story/article, not a comprehensive analysis of cell signalling and phenotype display
