Response to Comment on “Activation of methane to CH 3 + : A selective industrial route to methanesulfonic acid”
Christian Díaz-Urrutia
; Timo Ott
<jats:p>Roytman and Singleton argue that our proposed electrophilic mechanism for the sulfonation of methane in superacid conditions is “not plausible.” We clarify certain terms that might have caused misinterpretation of our proposed mechanism and supplement the discussion. We reaffirm that an electrophilic mechanism may be operative under our reaction conditions.</jats:p>

<jats:title>Proteasomal control of division in Archaea</jats:title> <jats:p> In eukaryotes, proteasome-mediated degradation of cell cycle factors triggers mitotic exit, DNA segregation, and cytokinesis, a process that culminates in abscission dependent on the protein ESCRT-III. By studying cell division in an archaeal relative of eukaryotes, Tarrason Risa <jats:italic>et al.</jats:italic> identified a role for the proteasome in triggering cytokinesis by an archaeal ESCRT-III homolog. Cell division in this archaeon was driven by stepwise remodeling of a composite ESCRT-III–based division ring, where rapid proteasome-mediated degradation of one ESCRT-III subunit triggered the constriction of the remaining ESCRT-III–based copolymer. These data strengthen the case for the eukaryotic cell division machinery having its origins in Archaea. </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.aaz2532">eaaz2532</jats:related-article> </jats:p>

Productivity in a pandemic
Caitlyn Collins
<jats:p>Almost overnight, coronavirus disease 2019 (COVID-19) has upended daily life, including the work of scientific research. But scientists have not experienced these new disruptions equally. You may have heard that women scientists seem to be submitting fewer papers for publication (including preprints), whereas men are submitting more. If this imbalance is correct, then the effects could include fewer women being granted tenure and promotion, a larger gender pay gap, and even some women being pushed out of science.</jats:p>
