<jats:title>Antibodies sustain viral control</jats:title> <jats:p> For many infected individuals, antiretroviral therapy (ART) means that an HIV-1 diagnosis is no longer a death sentence. But the virus persists in treated individuals, and complying with the intense drug regimen to keep virus loads down can be challenging for patients. Seeking an alternative, Byrareddy <jats:italic>et al.</jats:italic> treated ART-suppressed monkeys with antibodies targeting α4β7 integrin. When ART was halted in the antibody-treated animals, viral loads stayed undetectable, and normal CD4 T cell counts were maintained for over 9 months—and persisted—even after stopping the antibody therapy. </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="6309" page="197" related-article-type="in-this-issue" vol="354" xlink:href="10.1126/science.aag1276">197</jats:related-article> </jats:p> <jats:p> <jats:bold> Update: An Editorial Expression of Concern has been published <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="https://science.sciencemag.org/content/365/6457/991.1">here</jats:ext-link> </jats:bold> </jats:p>

<jats:title>Improving the stability of perovskite solar cells</jats:title> <jats:p> Inorganic-organic perovskite solar cells have poor long-term stability because ultraviolet light and humidity degrade these materials. Bella <jats:italic>et al.</jats:italic> show that coating the cells with a water-proof fluorinated polymer that contains pigments to absorb ultraviolet light and re-emit it in the visible range can boost cell efficiency and limit photodegradation. The performance and stability of inorganic-organic perovskite solar cells are also limited by the size of the cations required for forming a correct lattice. Saliba <jats:italic>et al.</jats:italic> show that the rubidium cation, which is too small to form a perovskite by itself, can form a lattice with cesium and organic cations. Solar cells based on these materials have efficiencies exceeding 20% for over 500 hours if given environmental protection by a polymer coating. </jats:p> <jats:p> <jats:italic>Science</jats:italic> , this issue pp. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6309" page="203" related-article-type="in-this-issue" vol="354" xlink:href="10.1126/science.aah4046">203</jats:related-article> and <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6309" page="206" related-article-type="in-this-issue" vol="354" xlink:href="10.1126/science.aah5557">206</jats:related-article> </jats:p>
