Following the lead of Jim O’Donnell at the National Maritime Museum and an earlier version that fetched articles using OAI, here's a YQL Open Data Table that allows Nature Publishing Group's article search to be queried using YQL:
USE "http://alf.hubmed.org/datatables/nature-opensearch.xml" as npg.articles;
SELECT * FROM npg.articles(1,5) WHERE query = "foxp2";
(1,5) are the starting item and number of items to return - leave that out to get the default number of items, starting from item 1.
Test in YQL console.
