<jats:title>Brain anatomy revealed in startling detail</jats:title> <jats:p> The mammalian cerebral cortex is an enormously complex network of neuronal processes that are long and thin, branching, and extremely densely packed. This high packing density has made the reconstruction of cortical neuronal networks challenging. Motta <jats:italic>et al.</jats:italic> used advanced automated imaging and analysis tools to reconstruct with high spatial resolution the morphological features of 89 neurons and their connections in the mouse barrel cortex. The reconstruction covered an area more than two orders of magnitude larger than earlier neuroanatomical mapping attempts. This approach revealed information about the connectivity of inhibitory and excitatory synapses of corticocortical as well as excitatory thalamocortical connections. </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.aay3134">eaay3134</jats:related-article> </jats:p>

<jats:p>Holding a major international summit on climate change against a backdrop of civil discontent like the kind that has rocked Chile might have given the world the impression that issues like clean energy can be addressed without also confronting problems of social justice. So last month, in the midst of massive protests on cost-of-living burdens and other inequalities, Chile withdrew as the host nation of the United Nations Climate Change Conference (COP25). Instead, COP25 will convene next week in Madrid, Spain. Despite this decision, Chile's commitment to maintain its presidency of COP25 through next year hopefully signals a turning point in climate action—one that further steers Chile and the rest of the global community to recognize connections between social and climate crises, and to support climate policies that do not leave anyone behind.</jats:p>
