Recommendations for accelerating open preprint peer review to improve the culture of science.

Peer review is an important part of the scientific process, but traditional peer review at journals is coming under increased scrutiny for its inefficiency and lack of transparency. As preprints become more widely used and accepted, they raise the possibility of rethinking the peer-review process. Preprints are enabling new forms of peer review that have the potential to be more thorough, inclusive, and collegial than traditional journal peer review, and to thus fundamentally shift the culture of peer review toward constructive collaboration. In this Consensus View, we make a call to action to stakeholders in the community to accelerate the growing momentum of preprint sharing and provide recommendations to empower researchers to provide open and constructive peer review for preprints.

Peer Review beyond Journals.

The EMBO Journal has extended its Transparent Process beyond journal confines to post referee comments alongside preprint versions of papers and to partner with Review Commons, a pre-journal peer-review platform for Refereed Preprints in the life sciences.

Review Commons-pre-journal peer review.

EMBO Press and ASAPbio launch Review Commons, a platform to provide authors with journal-independent peer review of their manuscripts and preprints.

A data citation roadmap for scientific publishers.

This article presents a practical roadmap for scholarly publishers to implement data citation in accordance with the Joint Declaration of Data Citation Principles (JDDCP), a synopsis and harmonization of the recommendations of major science policy bodies. It was developed by the Publishers Early Adopters Expert Group as part of the Data Citation Implementation Pilot (DCIP) project, an initiative of FORCE11.org and the NIH BioCADDIE program. The structure of the roadmap presented here follows the "life of a paper" workflow and includes the categories Pre-submission, Submission, Production, and Publication. The roadmap is intended to be publisher-agnostic so that all publishers can use this as a starting point when implementing JDDCP-compliant data citation. Authors reading this roadmap will also better know what to expect from publishers and how to enable their own data citations to gain maximum impact, as well as complying with what will become increasingly common funder mandates on data transparency.

Publishing peer review materials.

Publishing peer review materials alongside research articles promises to make the peer review process more transparent as well as making it easier to recognise these contributions and give credit to peer reviewers. Traditionally, the peer review reports, editors letters and author responses are only shared between the small number of people in those roles prior to publication, but there is a growing interest in making some or all of these materials available. A small number of journals have been publishing peer review materials for some time, others have begun this practice more recently, and significantly more are now considering how they might begin. This article outlines the outcomes from a recent workshop among journals with experience in publishing peer review materials, in which the specific operation of these workflows, and the challenges, were discussed. Here, we provide a draft as to how to represent these materials in the JATS and Crossref data models to facilitate the coordination and discoverability of peer review materials, and seek feedback on these initial recommendations.

Pressing needs of biomedical text mining in biocuration and beyond: opportunities and challenges.

Text mining in the biomedical sciences is rapidly transitioning from small-scale evaluation to large-scale application. In this article, we argue that text-mining technologies have become essential tools in real-world biomedical research. We describe four large scale applications of text mining, as showcased during a recent panel discussion at the BioCreative V Challenge Workshop. We draw on these applications as case studies to characterize common requirements for successfully applying text-mining techniques to practical biocuration needs. We note that system 'accuracy' remains a challenge and identify several additional common difficulties and potential research directions including (i) the 'scalability' issue due to the increasing need of mining information from millions of full-text articles, (ii) the 'interoperability' issue of integrating various text-mining systems into existing curation workflows and (iii) the 'reusability' issue on the difficulty of applying trained systems to text genres that are not seen previously during development. We then describe related efforts within the text-mining community, with a special focus on the BioCreative series of challenge workshops. We believe that focusing on the near-term challenges identified in this work will amplify the opportunities afforded by the continued adoption of text-mining tools. Finally, in order to sustain the curation ecosystem and have text-mining systems adopted for practical benefits, we call for increased collaboration between text-mining researchers and various stakeholders, including researchers, publishers and biocurators.

Ultrathin two-dimensional superconductivity with strong spin-orbit coupling.

We report on a study of epitaxially grown ultrathin Pb films that are only a few atoms thick and have parallel critical magnetic fields much higher than the expected limit set by the interaction of electron spins with a magnetic field, that is, the Clogston-Chandrasekhar limit. The epitaxial thin films are classified as dirty-limit superconductors because their mean-free paths, which are limited by surface scattering, are smaller than their superconducting coherence lengths. The uniformity of superconductivity in these thin films is established by comparing scanning tunneling spectroscopy, scanning superconducting quantum interference device (SQUID) magnetometry, double-coil mutual inductance, and magneto-transport, data that provide average superfluid rigidity on length scales covering the range from microscopic to macroscopic. We argue that the survival of superconductivity at Zeeman energies much larger than the superconducting gap can be understood only as the consequence of strong spin-orbit coupling that, together with substrate-induced inversion-symmetry breaking, produces spin splitting in the normal-state energy bands that is much larger than the superconductor's energy gap.

Stress and addiction: glucocorticoid receptor in dopaminoceptive neurons facilitates cocaine seeking.

The glucocorticoid receptor is a ubiquitous transcription factor mediating adaptation to environmental challenges and stress. Selective Nr3c1 (the glucocorticoid receptor gene) ablation in mouse dopaminoceptive neurons expressing dopamine receptor 1a, but not in dopamine-releasing neurons, markedly decreased the motivation of mice to self-administer cocaine, dopamine cell firing and the control exerted by dopaminoceptive neurons on dopamine cell firing activity. In contrast, anxiety was unaffected, indicating that glucocorticoid receptors modify a number of behavioral disorders through different neuronal populations.

CREB has a context-dependent role in activity-regulated transcription and maintains neuronal cholesterol homeostasis.

Induction of specific gene expression patterns in response to activity confers functional plasticity to neurons. A principal role in the regulation of these processes has been ascribed to the cAMP responsive element binding protein (CREB). Using genome-wide expression profiling in mice lacking CREB in the forebrain, accompanied by deletion of the cAMP responsive element modulator gene (CREM), we here show that the role of these proteins in activity-induced gene expression is surprisingly selective and highly context dependent. Thus, only a very restricted subset of activity-induced genes (i.e., Gadd45b or Nr4a2) requires these proteins for their induction in the hippocampus after kainic acid administration, while they are required for most of the cocaine-induced expression changes in the striatum. Interestingly, in the absence of CREB, CREM is able to rescue activity-regulated transcription, which strengthens the notion of overlapping functions of the two proteins. In addition, we show that cholesterol metabolism is dysregulated in the brains of mutant mice, as reflected coordinated expression changes in genes involved in cholesterol synthesis and neuronal accumulation of cholesterol. These findings provide novel insights into the role of CREB and CREM in stimulus-dependent transcription and neuronal homeostasis.
