<jats:title>A rapid screen for complex reactants</jats:title> <jats:p> Chemists engaged in reaction discovery tend to report outcomes involving a few, relatively simple reactants. It remains a major challenge to fine-tune reported conditions when the reactants become more structurally complex, as often happens in pharmaceutical research. Lin <jats:italic>et al.</jats:italic> developed a protocol for rapidly screening different catalytic conditions for C–N coupling across a wide range of complex substrates. The product detection scheme relies on mass spectrometry of nanomole-scale reaction mixtures without any need for intervening chromatography. </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="6402" page="eaar6236" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aar6236">eaar6236</jats:related-article> </jats:p>

Comment on “Unexpected reversal of C 3 versus C 4 grass response to elevated CO 2 during a 20-year field experiment”
Julie Wolf; Lewis Ziska
<jats:p> Reich <jats:italic>et al</jats:italic> . (Reports, 20 April 2018, p. 317) assert that the responses of C <jats:sub>3</jats:sub> and C <jats:sub>4</jats:sub> grass biomass to elevated CO <jats:sub>2</jats:sub> “challenge the current C <jats:sub>3</jats:sub> -C <jats:sub>4</jats:sub> [elevated CO <jats:sub>2</jats:sub> ] paradigm,” but these responses can be explained by the natural history of the experimental plants and soils without challenging this paradigm. </jats:p>

Dissipative Kerr solitons in optical microresonators
Tobias J. Kippenberg; Alexander L. Gaeta; Michal Lipson; Michael L. Gorodetsky
<jats:title>Shrinking optical metrology</jats:title> <jats:p> The ability to generate laser frequency combs—light sources comprising equidistant laser lines spanning a large range of wavelengths—has revolutionized metrology and precision spectroscopy. The past decade has seen frequency combs being generated in optical microresonator circuits, offering the prospect of shifting precision metrology applications from the realm of national laboratories to that of everyday devices. Kippenberg <jats:italic>et al.</jats:italic> review the development of microresonator-generated frequency combs and map out how understanding and control of their generation is providing a new basis for precision technology. </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="6402" page="eaan8083" related-article-type="in-this-issue" vol="361" xlink:href="10.1126/science.aan8083">eaan8083</jats:related-article> </jats:p>
