<jats:title>Toward quantum teleportation on demand</jats:title> <jats:p> Quantum information processing relies on the ability to store, manipulate, and propagate information encoded in quantum states of matter. Doing so, however, may destroy or compromise these delicate quantum states. Pfaff <jats:italic>et al.</jats:italic> present a quantum teleportation protocol that uses two defects in diamond 3 m apart (see the Perspective by Atatüre and Morton). They then map the quantum state of one of the diamond defects onto the other. The work presents a key building block for the successful development of larger 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="6196" page="532" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1253512">532</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6196" page="510" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1256698">510</jats:related-article> </jats:p>

<jats:title>A neuropeptide kills patient's motivation</jats:title> <jats:p> Chronic pain is not only extremely disturbing and unpleasant; it can also make people depressed and demotivated. What causes these effects? Schwartz <jats:italic>et al.</jats:italic> discovered that chronic pain causes changes in the way a neuropeptide called galanin affects certain neurons in a brain region called the nucleus accumbens (see the Perspective by Fields). Galanin influences a variety of behaviors, including feeding and certain aspects of pain. In this case, it depresses synaptic transmission at specific excitatory synapses. It does so, in part, by changing the ratio of subunits of an important receptor protein. </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="6196" page="535" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1253994">535</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6196" page="513" related-article-type="in-this-issue" vol="345" xlink:href="10.1126/science.1258477">513</jats:related-article> </jats:p>
