Four years, 400 articles, IF 5.4, and fast-track into PubMed

We published our first issue of Molecular Metabolism in December 2012, and we have been working hard over the last 4 years to establish the journal as a leading voice of the metabolism research community. Since that first issue, we now have published over 400 articles, received an initial impact factor of 5.4, and, just recently, been accepted for direct indexing in the National Library of Medicine (NLM). While we were already indexed in Pub Med Central (PMC), indexing in NLM means that from this issue forward, as soon as an article is accepted, it will appear in PMC rather than appearing after an issue has been paginated (typically 6e12 weeks after acceptance). These may seem like small steps, but in order to disseminate science as quickly as possible and to as wide an audience as possible, these steps actually represent giant strides for the journal toward increased speed, visibility, and impact. Importantly, 2017 promises to be another exciting year for the journal. In this issue, we are pleased to publish an important commentary by former Harvard Medical School Dean Jeffrey Flier on the irreproducibility of scientific research. This timely paper addresses the
