Paper published using my work
Unfortunately, your institution is the most likely avenue for recourse in these situations. I believe most journals leave it up the authors to sort this out and direct you to your university or institution for adjudication, despite spelling out the various and detailed criteria for authorship. Even if the editor agrees with you, any authorship changes after publication must be approved by all the current authors. I don't mean to be overly cynical but getting your name on that paper would require an exceptionally ethical and proactive worker/administrator at your institution. Seems like quite the uphill battle to me...  Here are the relevant links to Nature and Science:
