<jats:title>How perovskites have the edge</jats:title> <jats:p> Two-dimensional Ruddlesden-Popper perovskites form quantum wells by sandwiching inorganic-organic perovskite layers used in photovoltaic devices between organic layers. Blancon <jats:italic>et al.</jats:italic> show that if the perovskite layer is more than two unit cells thick, photogenerated excitons undergo an unusual but highly efficient process for creating free carriers that can be harvested in photovoltaic devices (see the Perspective by Bakr and Mohammed). Lower-energy local states at the edges of the perovskite layer facilitate dissociation into electrons and holes that are well protected from recombination. </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" issue="6331" page="1288" related-article-type="in-this-issue" vol="355" xlink:href="10.1126/science.aal4211">1288</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6331" page="1260" related-article-type="in-this-issue" vol="355" xlink:href="10.1126/science.aam7154">1260</jats:related-article> </jats:p>

<jats:p> Synergy between copper and zinc oxide on a catalyst surface facilitates methanol synthesis via CO <jats:sub>2</jats:sub> hydrogenation. </jats:p>

<jats:p>Linguistically, the generic use of “you” enables people to distance themselves from negative experiences and to extract some meaning from them.</jats:p>

<jats:p>Regions of high human population density drive highly localized transmission chains of dengue virus, which then can disperse regionally.</jats:p>
