<jats:title>The blood proteome in disease</jats:title> <jats:p> Understanding the function of human blood serum proteins in disease has been limited by difficulties in monitoring their production, accumulation, and distribution. Emilsson <jats:italic>et al.</jats:italic> investigated human serum proteins of more than 5000 Icelanders over the age of 65. The composition of blood serum includes a complex regulatory network of proteins that are globally coordinated across most or all tissues. The authors identified modules and functional groups associated with disease and health outcomes and were able to link genetic variants to complex diseases. </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="6404" page="769" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aaq1327">769</jats:related-article> </jats:p>

<jats:title>Moons drive structure in Jupiter's aurorae</jats:title> <jats:p> Like Earth, Jupiter has aurorae generated by energetic particles hitting its atmosphere. Those incoming particles can come from Jupiter's moons Io and Ganymede. Mura <jats:italic>et al.</jats:italic> used infrared observations from the Juno spacecraft to image the moon-generated aurorae. The pattern induced by Io showed an alternating series of spots, reminiscent of vortices, and sometimes split into two arcs. Aurorae related to Ganymede could also show a double structure. Although the cause of these unexpected features remains unknown, they may provide a way to examine how the moons produce energetic particles or how the particles propagate to Jupiter. </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="6404" page="774" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aat1450">774</jats:related-article> </jats:p>

<jats:title>An elevated lithium battery</jats:title> <jats:p> Batteries based on lithium metal and oxygen could offer energy densities an order of magnitude larger than that of lithium ion cells. But, under normal operation conditions, the lithium oxidizes to form peroxide or superoxide. Xia <jats:italic>et al.</jats:italic> show that, at increased temperatures, the formation of lithium oxide is favored, through a process in which four electrons are transferred for each oxygen molecule (see the Perspective by Feng <jats:italic>et al.</jats:italic> ). Reversible cycling is achieved through the use of a thermally stable inorganic electrolyte and a bifunctional catalyst for both oxygen reduction and evolution reactions. </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="6404" page="777" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aas9343">777</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6404" page="758" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aau4792">758</jats:related-article> </jats:p>

<jats:title>Dirac fermions in quasicrystalline graphene</jats:title> <jats:p> Quasicrystal lattices, which can have rotational order but lack translational symmetry, can be used to explore electronic properties of materials between crystals and disordered solids. Ahn <jats:italic>et al.</jats:italic> grew graphene bilayers rotated exactly 30° that have 12-fold rotational order. Electron diffraction and microscopy confirmed the formation of quasicrystals, and angle-resolved photoemission spectroscopy revealed anomalous interlayer electronic coupling that was quasi-periodic. The millimeter-scale layers can potentially be transferred to other substrates. </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="6404" page="782" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aar8412">782</jats:related-article> </jats:p>

<jats:title>A preference for acids</jats:title> <jats:p> When titanium dioxide surfaces are exposed to water under ambient conditions, an ordered overlayer forms. Balajka <jats:italic>et al.</jats:italic> studied this process with scanning tunneling microscopy and x-ray photoelectron spectroscopy for water adsorption under vacuum conditions and in air (see the Perspective by Park). The ordered overlayer was only formed in air, the result of the adsorption of organic acids (formic and acetic acids). Although other species such as alcohols were present in much higher concentrations in air, the bidentate adsorption and entropic effects favored acid adsorption. </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="6404" page="786" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aat6752">786</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6404" page="753" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aau6016">753</jats:related-article> </jats:p>
