Something I'd like to do (someone else asked for an e.g.) is look back at programming language searches, as they'll nearly always have the lang in the query. I'd be able to see when I started learning e.g. python and had to google everything, when I picked up other languages, how those searches decreased (or increased) as I learned more. Lots of interesting stuff.
"Combing through the correlations", it seems, literally means calculating the (Pearson) correlation between two variables (success vs. an input feature) and adding some interpretation, as they do on p6 of the arXiv paper. For test/training data, it looks like they just used a 30/70% split rather than k-fold cross-validation and holdout, but I'm sure it makes no difference either way and in this case (as often) is trivial to design and implement. Presumably their AUROC could be increased just by dropping in an SVM or a Random Forest in place of the logistic regression.
From what I've skimmed of the paper you're over-estimating the complexity of the study.

In fact, apparently in Iran almost 70% of science graduates are female [1], making the courses less diverse in terms of gender than the US, which I believe is closer to 50/50 for "science" collectively (can't find data).

It drives me insane.
Example: "Spy Kids" got a 93% fresh rating from critics, but 45% from audience ratings.
Code attached should you want to investigate for yourself.

Seems to be what's coming up here; personally I had no idea they were this far from consumer-ready.
Also I suggest reviewing high school biology, glycolysis isn't simple the breakdown of glucose into simpler molecules but involves many seemingly complex stages of isomerisation and reactions which are shepherded under specific conditions within various enzyme's active sites.
Consider reading the paper for more information: http://msb.embopress.org/content/10/4/725

Why do we even need the dated journal model? Push everything to a central arXiv, biorXiv like repo (funded as they are by small donations from institutions). Couple this with open post-publication peer review and endorsements. Millions of tax dollars saved around the world, research open to everyone.
The counter argument is the rubber stamp that accompanies a prestigious journal (and filtering the crazies) but if the repo was accompanied with a suitable array of article-level metrics and thorough categorisation the good science can continue to filter to the top, much like how HN and reddit work.
