<jats:title>Cross-cultural analysis of song</jats:title> <jats:p> It is unclear whether there are universal patterns to music across cultures. Mehr <jats:italic>et al.</jats:italic> examined ethnographic data and observed music in every society sampled (see the Perspective by Fitch and Popescu). For songs specifically, three dimensions characterize more than 25% of the performances studied: formality of the performance, arousal level, and religiosity. There is more variation in musical behavior within societies than between societies, and societies show similar levels of within-society variation in musical behavior. At the same time, one-third of societies significantly differ from average for any given dimension, and half of all societies differ from average on at least one dimension, indicating variability across cultures. </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.aax0868">eaax0868</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6468" page="944" related-article-type="in-this-issue" vol="366" xlink:href="10.1126/science.aay2214">944</jats:related-article> </jats:p>

<jats:title>Thinking small to store more</jats:title> <jats:p> From mobile devices to the power grid, the needs for high-energy density or high-power density energy storage materials continue to grow. Materials that have at least one dimension on the nanometer scale offer opportunities for enhanced energy storage, although there are also challenges relating to, for example, stability and manufacturing. In this context, Pomerantseva <jats:italic>et al.</jats:italic> review fundamental processes of charge storage that apply specifically to nanostructured materials and briefly explore potential manufacturing processes. The authors also consider some of the skepticism, such as that found in the battery community, to the use of these materials. </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.aan8285">eaan8285</jats:related-article> </jats:p>

<jats:p>The term “diversity,” which came about in connection with the passage of the U.S. Civil Rights Act of 1964, has been expanding to include an ever-growing list of identities—from race, gender, and sexual orientation to physical appearance, belief systems, thought styles, socioeconomic status, and rural/urban geographic location, among others. This is a welcome extension of representation, but this added texture has a downside—it threatens to muddle targets and obscure actions when achieving diversity is the goal. This consequence is particularly serious in the context of addressing equity for specific underrepresented racial and ethnic groups. Next week, the U.S. National Academies will convene the Roundtable on Black Men and Black Women in Science, Engineering and Medicine to focus on confronting issues that threaten the future of Blacks broadly in science. Forging systemic changes that bring Black diversity at all education and career levels will hopefully bring racial equity to practices in these fields and in doing so, expand the benefits of science, engineering, and medicine to society.</jats:p>
