<jats:title>Fungal disease meets its match</jats:title> <jats:p> <jats:italic>Fusarium</jats:italic> head blight (FHB), caused by a fungus, reduces wheat crop yield and introduces toxins into the harvest. From the assembly of the genome of <jats:italic>Thinopyrum elongatum</jats:italic> , a wild relative of wheat used in breeding programs to improve cultivated wheat, Wang <jats:italic>et al.</jats:italic> cloned a gene that can address both problems (see the Perspective by Wulff and Jones). The encoded glutathione <jats:italic>S</jats:italic> -transferase detoxifies the trichothecene toxin and, when expressed in wheat, confers resistance to FHB. </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.aba5435">eaba5435</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6493" page="822" related-article-type="in-this-issue" vol="368" xlink:href="10.1126/science.abb9991">822</jats:related-article> </jats:p>

<jats:title>Social animals need connection</jats:title> <jats:p> Much research over the past decade or so has revealed that health and lifespan in humans, highly social animals, are reduced with social adversity. We humans are not the only animals that are social, however, and similar research has shown that other social mammals are similarly influenced by isolation and adversity. Snyder-Mackler <jats:italic>et al.</jats:italic> reviewed the relationships between social environment and many aspects of health and well-being across nonhuman mammals and investigated the similarities between these and patterns in humans. They found many of the same threats and responses across social mammals. </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.aax9553">eaax9553</jats:related-article> </jats:p>

<jats:p>The notion that U.S. colleges and universities will open this fall in “normal” mode should not be in any forecast. As Dr. Anthony Fauci (of the White House's coronavirus task force) testified last week before the Senate, it's unlikely that a vaccine or treatments for coronavirus disease 2019 (COVID-19) will be available by the time students return to campus. I sympathize with the predicament of college and university administrators who need to reopen in ways that are safe and supportive for all their students while also planning for the possibility that they won't be able to reopen in-person classes. To help them grapple with this, let's suspend two things, at least temporarily—test scores and rankings.</jats:p>
