<p>In the abstract, the term &#x201c;SQ radicals&#x201d; was erroneously used instead of &#x201c;semiquinone radicals (Q&#x2022;<sup>-</sup>)&#x201d;. This has been corrected to read:</p>
<p>&#x201c;Here we show that under membrane-less in-solution conditions, H<sub>2</sub> modulates O<sub>2</sub>&#x2022;<sup>-</sup> kinetics in ways consistent with a tunneling-assisted electron transfer involving semiquinone radicals (Q&#x2022;<sup>-</sup>), without catalytic metals or hydrogenases&#x201d;.</p>
<p>The original article has been updated.</p>
