<jats:title>Probing magnetic reconnection in space</jats:title> <jats:p> Magnetic reconnection occurs when the magnetic field permeating a conductive plasma rapidly rearranges itself, releasing energy and accelerating particles. Reconnection is important in a wide variety of physical systems, but the details of how it occurs are poorly understood. Burch <jats:italic>et al.</jats:italic> used NASA's Magnetospheric Multiscale mission to probe the plasma properties within a reconnection event in Earth's magnetosphere (see the Perspective by Coates). They find that the process is driven by the electron-scale dynamics. The results will aid our understanding of magnetized plasmas, including those in fusion reactors, the solar atmosphere, solar wind, and the magnetospheres of Earth and other planets. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.aaf2939">10.1126/science.aaf2939</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6290" page="1176" related-article-type="in-this-issue" vol="352" xlink:href="10.1126/science.aaf7269">1176</jats:related-article> </jats:p>

<jats:title>A balancing act in modifying chromatin</jats:title> <jats:p>Chromatin modifiers add chemical groups to histones, the proteins that package DNA. These modifications are central to cellular development, and mutations in their molecular machinery are linked to a variety of human diseases. Piunti and Shilatifard review the balance between the prototypic chromatin modifiers Polycomb and COMPASS complexes and their role in gene regulation and normal development. Although originally identified as indispensible regulators of fruit fly development, related roles have been identified in other organisms. Furthermore, mutations in human homologs have been implicated in various cancers. As such, these complexes may serve as effective targets for epigenetic therapies.</jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" related-article-type="in-this-issue" xlink:href="10.1126/science.aad9780">10.1126/science.aad9780</jats:related-article> </jats:p>

<jats:p> Nearly 1 year ago, a group of researchers boldly suggested that the standards for research quality, transparency, and trustworthiness could be improved if journals banded together to adopt eight standards called TOP (Transparency and Openness Promotion). <jats:xref ref-type="fn">*</jats:xref> Since that time, more than 500 journals have been working toward their implementation of TOP. The editors at <jats:italic>Science</jats:italic> have held additional retreats and workshops to determine how best to adapt TOP to a general science journal and are now ready to announce our new standards, effective 1 January 2017. <jats:xref ref-type="fn">†</jats:xref> </jats:p>
