<jats:title>You Must Be Human</jats:title> <jats:p> Are there specific brain structures associated with social cognition or with aspects of information processing that frequently occur together with social cognition? <jats:bold> Carter <jats:italic>et al.</jats:italic> </jats:bold> (p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" page="109" related-article-type="in-this-issue" vol="337" xlink:href="10.1126/science.1219681">109</jats:related-article> ) invited subjects to play a simplified virtual poker game against either a human or a computer and examined brain scans collected during the game. The brains scans when the cards shown were used to predict the participant's decision 6 seconds later. Activity in one region, the temporal-parietal junction, was one of the best predictors of future decisions against a human opponent, but the single worst predictor against a computer opponent. </jats:p>

<jats:p>Nanotechnology-based tools and treatments promise sensitive disease diagnosis and accurate drug delivery. Most important, the physical features of nanometer-size materials provide capabilities that larger objects cannot match. Nonetheless, some of the challenges, such as biocompatibility and toxicity, require ongoing research and improved solutions. Despite these obstacles, some nanoscale approaches to medicine can already be used.</jats:p>
