<jats:title>Solar Snow Lines</jats:title> <jats:p> Models of the formation of our solar system have suggested that condensation lines, or snow lines—the distance from a star beyond which a gas or a liquid can condense into the solid phase—are favorable locations for planet formation. Taking advantage of the increase of N <jats:sub>2</jats:sub> H <jats:sup>+</jats:sup> abundance in cold regions where CO condenses out of the gas phase, <jats:bold> Qi <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6146" page="630" related-article-type="in-this-issue" vol="341" xlink:href="10.1126/science.1239560">630</jats:related-article> , published online 18 July) used the Atacama Large Millimeter/Submillimeter Array to image the CO snow line in the disk around TW Hya, an analog of the solar nebula from which the solar system formed. This disk's snow line corresponds to Neptune's orbit in our solar system. </jats:p>

<jats:title>Strongly Correlated Clocks</jats:title> <jats:p> Optical lattice clocks with alkaline earth atoms provide one of the most stable time-keeping systems. Such clocks, in general, exhibit shifts in their transition frequencies as a consequence of interactions between atoms. Can this sensitivity be used to explore the dynamics of strongly correlated quantum systems? <jats:bold> Martin <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6146" page="632" related-article-type="in-this-issue" vol="341" xlink:href="10.1126/science.1236929">632</jats:related-article> ) used a 1-dimensional optical lattice clock to study quantum many-body effects. Whereas the clock shift itself could be modeled within the mean field approximation, quantities such as spin noise required a full many-body treatment. This system may be useful for the quantum simulation of exotic magnetism. </jats:p>
