Nothing like searching for an answer (PMIDs->Bibtex) and finding someone else pointing back to your own solution! http://t.co/ZOm0cK6o0d

The blog post in question concerns conversion of PubMed PMIDs to BibTeX citations. However, a few things have changed since 2010.

Here’s what currently works.

	# pmid2bibtex.rb
	# convert a PubMed PMID to BibTeX citation format
	# updated version of http://chrisamiller.com/science/2010/12/13/using-bioruby-to-fetch-citations-from-pubmed/
	# works as of 2015-03-18
	require 'bio'
	Bio::NCBI.default_email = "me@me.com" # required for EUtils
	id = "18265351"
	pm = Bio::PubMed::efetch(id) # array of MEDLINE-formatted string
	med = Bio::MEDLINE.new(pm[0]) # MEDLINE object
	bib = med.reference.format("bibtex") # format is a method of Reference object
	# "@article{PMID:18265351,\n author = {Brown, T. and Mackey, K. and Du, T.},\n title = {Analysis of RNA by northern
	# and slot blot hybridization.},\n journal = {Curr Protoc Mol Biol},\n year = {2004},\n volume = {Chapter
	# 4},\n pages = {Unit 4.9},\n url = {http://www.ncbi.nlm.nih.gov/pubmed/18265351},\n}\n"
