<jats:title>The future of meat</jats:title> <jats:p> Meat consumption is rising annually as human populations grow and affluence increases. Godfray <jats:italic>et al.</jats:italic> review this trend, which has major negative consequences for land and water use and environmental change. Although meat is a concentrated source of nutrients for low-income families, it also enhances the risks of chronic ill health, such as from colorectal cancer and cardiovascular disease. Changing meat consumption habits is a challenge that requires identifying the complex social factors associated with meat eating and developing policies for effective interventions. </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.aam5324">eaam5324</jats:related-article> </jats:p>

<jats:title>Simulating South American biodiversity</jats:title> <jats:p> The emergence, distribution, and extinction of species are driven by interacting factors—spatial, temporal, physical, and biotic. Rangel <jats:italic>et al.</jats:italic> simulated the past 800,000 years of evolution in South America, incorporating these factors into a spatially explicit dynamic model to explore the geographical generation of diversity. Their simulations, based on a paleoclimate model on a 5° latitude-longitude scale, result in shifting maps of speciation, persistence, and extinction (or cradles, museums, and graves). The simulations culminate in a striking resemblance to contemporary distribution patterns across the continent for birds, mammals, and plants—despite having no target patterns and no empirical data parameterizing them. </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.aar5452">eaar5452</jats:related-article> </jats:p>

<jats:title>'Tis the seasonal</jats:title> <jats:p> Anthropogenic climate change has become clearly observable through many metrics. These include an increase in global annual temperatures, growing heat content of the oceans, and sea level rise owing to the melting of the polar ice sheets and glaciers. Now, Santer <jats:italic>et al.</jats:italic> report that a human-caused signal in the seasonal cycle of tropospheric temperature can also be measured (see the Perspective by Randel). They use satellite data and the anthropogenic “fingerprint” predicted by climate models to show the extent of the effects and discuss how these changes have been caused. </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.aas8806">eaas8806</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6399" page="227" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aat9097">227</jats:related-article> </jats:p>

<jats:p>This week in Pasadena, California, the International Council for Science will convene its Committee on Space Research (COSPAR) Scientific Assembly to promote the exchange of results, information, and opinions in space research. Since its creation 60 years ago, on the heels of the 1957 launch of Sputnik by the Soviet Union and of Explorer 1 by the United States in early 1958—events that marked the dawn of the space age—COSPAR has nurtured partnerships between nations pursuing space science. There is a new space age now—one with many more players and exciting technologies to harness. New capacity-building endeavors at universities worldwide are providing opportunities for involvement in space missions, both great and small.</jats:p>
