<jats:title>A comparison of DFT methods</jats:title> <jats:p> Density functional theory (DFT) is now routinely used for simulating material properties. Many software packages are available, which makes it challenging to know which are the best to use for a specific calculation. Lejaeghere <jats:italic>et al.</jats:italic> compared the calculated values for the equation of states for 71 elemental crystals from 15 different widely used DFT codes employing 40 different potentials (see the Perspective by Skylaris). Although there were variations in the calculated values, most recent codes and methods converged toward a single value, with errors comparable to those of experiment. </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.aad3000">10.1126/science.aad3000</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6280" page="1394" related-article-type="in-this-issue" vol="351" xlink:href="10.1126/science.aaf3412">1394</jats:related-article> </jats:p>

Craig Venter

<jats:title>Designing and building a minimal genome</jats:title> <jats:p> A goal in biology is to understand the molecular and biological function of every gene in a cell. One way to approach this is to build a minimal genome that includes only the genes essential for life. In 2010, a 1079-kb genome based on the genome of <jats:italic>Mycoplasma mycoides</jats:italic> (JCV-syn1.0) was chemically synthesized and supported cell growth when transplanted into cytoplasm. Hutchison III <jats:italic>et al.</jats:italic> used a design, build, and test cycle to reduce this genome to 531 kb (473 genes). The resulting JCV-syn3.0 retains genes involved in key processes such as transcription and translation, but also contains 149 genes of unknown function. </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.aad6253">10.1126/science.aad6253</jats:related-article> </jats:p>

Einstein v. Roberts

S. J. Gates

<jats:p>In the recent U.S. Supreme Court hearing on A. Fisher v. the University of Texas about university admission policies regarding minority students, Chief Justice John Roberts asked, “What unique perspective does a minority student bring to a physics class?” As an African-American physicist researching string theory, and a teacher of university students since 1972, I have a response.</jats:p>
