<jats:title>Signaling at the synapse</jats:title> <jats:p> Neurons signal to each other at synapses using neurotransmitters. Glutamate is a key neurotransmitter, and AMPA-type glutamate receptors (AMPARs) mediate rapid responses to glutamate release. These receptors mainly occur as heteromers comprising GluA1-4 subunits. Herguedas <jats:italic>et al.</jats:italic> used electron microscopy and x-ray crystallography to determine the structure of GluA2/3 and GluA2/4 heteromers. The structures differ from those determined previously for GluA2 homomers but emphasize how signals may be transmitted through these dynamic receptors. </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.aad3873">10.1126/science.aad3873</jats:related-article> </jats:p>

<jats:p> Like many scientist-editors of journals published by nonprofit scientific societies, I have a love-hate relationship with Sci-Hub, the website operated out of Russia that provides access to 50 million pirated scientific articles to researchers worldwide (see the News story on p. <jats:ext-link xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="uri" xlink:href="http://www.sciencemag.org/content/352/6285/508">508</jats:ext-link> ). I recognize the underlying motivation of bringing global research content to the developing world. However, I also recognize that much traffic to Sci-Hub is from researchers who already have access to the articles they seek through mechanisms such as site licenses, open access, or other means. Authors who publish in <jats:italic>Science</jats:italic> journals, for example, can make their papers available immediately upon publication through free referrer links at the authors' websites. Research published after 1996 in a <jats:italic>Science</jats:italic> journal is made free with registration 1 year after its publication date. So what does the scientific community risk by gathering papers illegally? </jats:p>
