<jats:title>Animal sociability through microbes</jats:title> <jats:p> Accumulating evidence suggests that the microbiota living in and on animals has important functions in the social architecture of those animals. Sherwin <jats:italic>et al.</jats:italic> review how the microbiota might facilitate neurodevelopment, help program social behaviors, and facilitate communication in various animal species, including humans. Understanding the complex relationship between microbiota and animal sociability may also identify avenues for treating social disorders in humans. </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.aar2016">eaar2016</jats:related-article> </jats:p>

<jats:title>Achieving unconfined supersonic explosions</jats:title> <jats:p> In some forms of supernovae and chemical explosions, a flame moving at subsonic speeds (deflagration) spontaneously evolves into one driven by a supersonic shock (detonation), vastly increasing the power output. The mechanism of this deflagration-to-detonation transition (DDT) is poorly understood. Poludnenko <jats:italic>et al.</jats:italic> developed an analytical model to describe DDTs, then tested it with lab experiments and numerical simulations. Their model successfully reproduced the DDT seen in the experiments and predicted a DDT in type Ia supernovae, which is consistent with observational constraints. The same mechanism may apply to DDTs in any unconfined explosion. </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.aau7365">eaau7365</jats:related-article> </jats:p>

<jats:title>Cryptic signs of aging in our blood</jats:title> <jats:p>Time is not a friend to our DNA. Aging is associated with an accumulation of somatic mutations in normal dividing cells, including the hematopoietic stem cells (HSCs) that give rise to all blood cells. Certain mutations in HSCs confer a fitness advantage that results in clonal expansions of mutant blood cells that sometimes—but not always—forecast the development of cancer and other age-related diseases. Jaiswal and Ebert review this process of “clonal hematopoiesis,” including the mechanisms by which it arises and the current state of knowledge regarding its effects on human health.</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.aan4673">eaan4673</jats:related-article> </jats:p>

<jats:p> The long strange trip to where I am today—the new Editor-in-Chief of the <jats:italic>Science</jats:italic> family of journals—began in the theater. My mom started the community theater in my hometown and my experiences there taught me many things, but two stand out. First, I was a bad actor. My mom humored me for a while giving me parts, but she let out a huge sigh of relief when I decided I could contribute more with a wrench or a bass guitar in my hand than on the stage. </jats:p>
