(Photo: Courtesy of Marvit.)<\/figcaption><\/figure>\n<p>Marvit, who recently graduated with a bachelor\u2019s degree in human biology from the USC Dornsife College of Letters, Arts and Sciences, delves into the fascinating world of Time Lord physiology, focusing on their unique, dual-heart cardiovascular system.<\/p>\n<p>Time Lords, such as the central character of the TV show, are an advanced alien species with the ability to travel through time and space, regenerate their bodies, and live for centuries.<\/p>\n<p>Combining her scientific knowledge with creative speculation, Marvit explains how the Doctor\u2019s two hearts might function and evolve. She draws parallels with real-world biology, including cephalopod (think \u201coctopus\u201d) cardiovascular systems and human heart conditions, to create a plausible scientific framework for the fictional alien anatomy.<\/p>\n<p><em>Scientific American<\/em> spotted an early version of the article after Marvit received a student recognition award from Phi Kappa Phi, USC\u2019s oldest interdisciplinary honor society, for writing it.<\/p>\n<p>&#8220;Combining her love of science fiction with a deep knowledge of hard science \u2014 exemplifying the cross-disciplinary thinking at the heart of the Dornsife experience \u2014 Amelia shows us how imagination will always be the lifeblood of scientific hypothesis,\u201d said Emily Hodgson Anderson, college dean of undergraduate education. \u201cShe follows the grand tradition of natural philosophers, at a time when intellectual disciplines didn\u2019t exist, who could dream their way into discovery.\u201d<\/p>\n<p><a href=\"https:\/\/www.scientificamerican.com\/article\/doctor-whos-time-lords-have-two-hearts-heres-how-their-dual-cardiac-system\/\"><em>Read Marvit\u2019s full article in <\/em>Scientific American<em> &gt;&gt;<\/em><\/a><\/p>\n<div class=\"video-embed\"><iframe loading=\"lazy\" width=\"560\" height=\"315\" src=\"https:\/\/www.youtube.com\/embed\/lCTppkaeFbI?si=eMwVAIcOfve_fZqo\" frameborder=\"0\" allow=\"accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture; web-share\" referrerpolicy=\"strict-origin-when-cross-origin\" title=\"Doctor Who\u2019s Two Hearts, Explained\" allowfullscreen><\/iframe><\/div>\n\n\n\n<\/div>\n\n\n  <\/div><\/div>\n\n\n\n  \n        \n  \n    \n\n\n\n\n\n\n<div\n  class=\"cc--component-container cc--article-related-stories \"\n\n  \n  \n  \n  \n  \n  \n  >\n  <div class=\"c--component c--article-related-stories\"\n    \n      >\n\n    \n  <div class=\"inner-wrapper\">\n              \n<div class=\"f--field f--section-title\">\n\n    \n  <h2>\n          Related Articles\n      <\/h2>\n\n\n<\/div>\n    \n                  <article>\n              \n<div class=\"f--field f--cta-title\">\n\n    \n  <h3>\n          <a href=\"https:\/\/priceschool.usc.edu\/news\/us-army-rotc-usc-price\/\" \n         target=\"_blank\"                 class=\"\" \n      >History and ROTC prepared USC Dornsife grad for the military<\/a>\n      <\/h3>\n\n\n<\/div>\n        <\/article>\n              <article>\n              \n<div class=\"f--field f--cta-title\">\n\n    \n  <h3>\n          <a href=\"https:\/\/dornsife.usc.edu\/news\/stories\/how-usc-dornsife-helped-shape-singer-songwriter-aloe-blaccs-career\/\" \n                        class=\"\" \n      >How USC Dornsife helped shape acclaimed singer-songwriter Aloe Blacc\u2019s career<\/a>\n      <\/h3>\n\n\n<\/div>\n        <\/article>\n              <article>\n              \n<div class=\"f--field f--cta-title\">\n\n    \n  <h3>\n          <a href=\"https:\/\/dornsife.usc.edu\/magazine\/fight-on\/\" \n         target=\"_blank\"                 class=\"\" \n      >Fight On!
