<jats:title>A missing link in cholesterol absorption</jats:title> <jats:p> Cholesterol is important for general health, but too much can build up in artery walls and cause cardiovascular disease. Low-density lipoprotein cholesterol (LDL-C) is often referred to as “bad cholesterol”; keeping LDL-C within stringent limits is recommended to reduce the risk of heart attack and stroke. Zhang <jats:italic>et al.</jats:italic> discovered that some individuals have an inherited frameshift mutation in the <jats:italic>LIMA1</jats:italic> gene (also known as <jats:italic>EPLIN</jats:italic> or <jats:italic>SREBP3</jats:italic> ). The gene has not been linked to lipid metabolism before, but altered <jats:italic>LIMA1</jats:italic> was found to maintain low plasma LDL-C by reducing the absorption of cholesterol through the intestine. Pharmacological targeting through the LIMA1 pathway might thus provide a strategy to improve heart health. </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="6393" page="1087" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aao6575">1087</jats:related-article> </jats:p>

<jats:title>Measuring martian organics and methane</jats:title> <jats:p> The Curiosity rover has been sampling on Mars for the past 5 years (see the Perspective by ten Kate). Eigenbrode <jats:italic>et al.</jats:italic> used two instruments in the SAM (Sample Analysis at Mars) suite to catch traces of complex organics preserved in 3-billion-year-old sediments. Heating the sediments released an array of organics and volatiles reminiscent of organic-rich sedimentary rock found on Earth. Most methane on Earth is produced by biological sources, but numerous abiotic processes have been proposed to explain martian methane. Webster <jats:italic>et al.</jats:italic> report atmospheric measurements of methane covering 3 martian years and found that the background level varies with the local seasons. The seasonal variation provides an important clue for determining the origin of martian methane. </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="6393" page="1096" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aas9185">1096</jats:related-article> , p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6393" page="1093" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aaq0131">1093</jats:related-article> ; see also p. <jats:related-article xmlns:xlink="http://www.w3.org/1999/xlink" ext-link-type="doi" issue="6393" page="1068" related-article-type="in-this-issue" vol="360" xlink:href="10.1126/science.aat2662">1068</jats:related-article> </jats:p>
