What I don't like is how the press and often scientists make every paper seem like something was newly identified. With no disrespect to the authors of this particular study, they didn't "unveil a new pathway". Several previous works over the past decade have honed in on this exact "master switch". E.g., Identification of FTO as relevant to obesity (2007): http://www.ncbi.nlm.nih.gov/pubmed/17434869 http://www.ncbi.nlm.nih.gov/pubmed/17434869 Connection of FTO and IRX3 (2014): http://www.ncbi.nlm.nih.gov/pubmed/?term=24646999 http://www.ncbi.nlm.nih.gov/pubmed/?term=24646999
