Since the creation of Sleep Science, in 2008, it has never been a year as exciting as 2014. Over the past year, we accomplished two of the main goals of the editorial board: indexation in an international database (Scopus), including the indexation of our entire previous archive, and the management by a major scientific publisher, Elsevier.As part of Elsevier group, Sleep Science’s submissions are now handled by Elsevier Electronic System (EES) and newly published papers are immediately available in ScienceDirect. Since the migration to Elsevier, there has been a major increase in Sleep Science’s visibility, as well as a 50% increase in the number of submissions from outside Brazil, compared to the same period in 2013.In this December Issue, we have collected some of these studies from around the globe. Articles from USA, Portugal, Israel, Ecuador and Brazil compose the last Issue of 2014. Noteworthy, two of these papers are focused on environmental factors on sleep, with distinct perspectives. Halperin presents a very interesting theoretical essay about the influence of environmental noise on sleep disturbances, and their impact in general health [1]. In addition, the paper of Rebelo-Pinto et al. [2] discuss a three-dimensional model created from two sleep questionnaires that considers nine subcategories related to personal life’s habits and environmental influences, designed to study sleep habits and self-perception in a sample of adolescents and their parents. Both approaches can be helpful to comprehend the evolution of sleep disturbances, as well as to set specific goals in community intervention based programs.Nevertheless, we invite all of our readers to access the full content of this Issue in our website.
