<jats:title>Surveying the solar cell landscape</jats:title> <jats:p> The rate of development and deployment of large-scale photovoltaic systems over recent years has been unprecedented. Because the cost of photovoltaic systems is only partly determined by the cost of the solar cells, efficiency is a key driver to reduce the cost of solar energy. There are several materials systems being explored to achieve high efficiency at low cost. Polman <jats:italic>et al.</jats:italic> comprehensively and systematically review the leading candidate materials, present the limitations of each system, and analyze how these limitations can be overcome and overall cell performance improved. </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.aad4424">10.1126/science.aad4424</jats:related-article> </jats:p>

<jats:title>Blueprint for a macromolecular machine</jats:title> <jats:p> Nuclear pore complexes (NPCs) consist of around 1000 protein subunits, are embedded in the membrane that surrounds the nucleus, and regulate transport between the nucleus and the cytoplasm. Although the overall shape of NPCs is known, the details of this macromolecular complex have been obscure. Now, Lin <jats:italic>et al.</jats:italic> have reconstituted the pore components, determined the interactions between them, and fitted them into a tomographic reconstruction. Kosinski <jats:italic>et al.</jats:italic> have provided an architectural map of the inner ring of the pore. </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" related-article-type="in-this-issue" xlink:href="10.1126/science.aaf1015">10.1126/science.aaf1015</jats:related-article> and <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6283" page="363" related-article-type="in-this-issue" vol="352" xlink:href="10.1126/science.aaf0643">363</jats:related-article> </jats:p>

<jats:p> No member state has ever left the European Union (EU), and so the idea that the United Kingdom (UK) might leave has stirred fierce debate ever since Prime Minister David Cameron promised a referendum on membership nearly a year ago. On 23 June 2016, British citizens have a choice to make. Public opinion in the UK is split on a British exit from the EU, or a “Brexit.” A recent survey indicates that the majority of researchers favor the UK remaining in the EU. <jats:xref ref-type="fn">*</jats:xref> As a British scientist and former Chief Scientific Adviser to the President of the European Commission, I believe that it benefits the UK, the EU, and global science for the UK to remain a strong committed member of the EU. </jats:p>
