<jats:title>Corals and reef fish choose nice homes</jats:title> <jats:p> Young animals tend to disperse into new habitats. Can we use populations in protected areas to colonize nearby recovering or overused habitats? It seems that for corals and reef fish, the answer may be no. Dixson <jats:italic>et al.</jats:italic> show that dispersing juvenile corals and reef fish were overwhelmingly attracted to healthy reefs but were repelled by seaweeds that colonize degraded reefs (see the Perspective by Bruno). Thus, even species that appear passive in their choice of habitat may have stronger preferences than we thought. </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="6199" page="892" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1255057">892</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6199" page="879" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1258556">879</jats:related-article> </jats:p>

<jats:title>Deep-sea warming slows down global warming</jats:title> <jats:p>Global warming seems to have paused over the past 15 years while the deep ocean takes the heat instead. The thermal capacity of the oceans far exceeds that of the atmosphere, so the oceans can store up to 90% of the heat buildup caused by increased concentrations of greenhouse gases such as carbon dioxide. Chen and Tung used observational data to trace the pathways of recent ocean heating. They conclude that the deep Atlantic and Southern Oceans, but not the Pacific, have absorbed the excess heat that would otherwise have fueled continued warming.</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="6199" page="897" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1254937">897</jats:related-article> </jats:p>

<jats:title>Routing one photon with a few others</jats:title> <jats:p> Single particles of light, photons, are ideal carriers of quantum information because they can travel far and fast and don't interact much with each other. However, this behavior has hampered attempts to control the propagation of single photons using all-optical setups. Shomroni <jats:italic>et al.</jats:italic> coupled a trapped atom to an optic fiber. That allowed them to control the polarization and propagation direction of a single photon in the fiber by controlling the atom's state (see the Perspective by Rempe). Because a faint pulse containing between 1.5 and 3 photons can switch the atom's state, the scheme provides a route to develop all-optical quantum networks. </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="6199" page="903" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1254699">903</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6199" page="871" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1258142">871</jats:related-article> </jats:p>
