<jats:title>Invisible threat</jats:title> <jats:p>Our changing climate is a threat to corals, causing disfiguring bleaching and mortality to reefs that once teemed with life. Shlesinger and Loya alert us to an equally dangerous yet nearly invisible hazard to coral: loss of breeding synchrony (see the Perspective by Fogarty and Marhaver). They found that environmental changes have resulted in shifts in the timing of gamete release in several species of broadcast-spawning corals in the Red Sea. Similar changes are likely occurring globally. Such a loss of spawning synchrony could result in reproductive failure, a much less obvious but no less insidious threat to coral reefs.</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="6457" page="1002" related-article-type="in-this-issue" vol="365" xlink:href="10.1126/science.aax0110">1002</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6457" page="987" related-article-type="in-this-issue" vol="365" xlink:href="10.1126/science.aay7457">987</jats:related-article> </jats:p>

<jats:title>Unraveling the proton puzzle</jats:title> <jats:p> The discrepancy between the proton size deduced from the Lamb shift in muonic hydrogen and the average, textbook value based on regular (electronic) hydrogen has puzzled physicists for nearly a decade. One possible resolution could be that electrons interact with protons in a different way than muons do, which would require “new physics.” Bezginov <jats:italic>et al.</jats:italic> measured the Lamb shift in electronic hydrogen, which allowed for a direct comparison to the Lamb shift measured in muonic hydrogen. The two results agreed, but the discrepancy with the averaged value remains. </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="6457" page="1007" related-article-type="in-this-issue" vol="365" xlink:href="10.1126/science.aau7807">1007</jats:related-article> </jats:p>
