Mikucki, a University of Tennessee microbiologist who has been investigating the Taylor Glacier and Blood Falls for years. Their results appeared in Frontiers in Astronomy and Space Sciences.<\/p>\n<p style=\"text-align: left;\">A prolific Antarctic researcher, Mikucki was part of the team that first identified living organisms in the lake beneath the Taylor Glacier. That team mapped the water\u2019s source: an ancient, briny subglacial reservoir containing myriad minerals gathered by the ice in its crawl across the rocks below. The reason for the water\u2019s startling gory appearance, though, remained unclear. So Mikucki and astronomer Darby Dyar from Mount Holyoke College sent the samples to Livi at the Materials Characterization and Processing facility.<\/p>\n<p style=\"text-align: left;\">Livi, a planetary materials expert, says that the ancient, iron- and salt-rich waters under the Taylor Glacier host bacteria strains that may be millions of years old and could inform the search for life on other seemingly inhospitable planets, including Mars.<\/p>\n<p style=\"text-align: left;\">\u201cThere are microorganisms that have been existing for potentially millions of years underneath the saline waters of the Antarctic glacier,\u201d he says. \u201cThese are ancient waters.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Using powerful transmission electron microscopes, Ken Livi, an associate research scientist in the Department of Materials Science and Engineering and director of operations for the Whiting School of Engineering\u2019s Materials Characterization and Processing facility, examined samples of Blood Falls water and found an abundance of iron-rich nanospheres that oxidize, turning the water seemingly gory and solving a century-old mystery.<\/p>\n","protected":false},"author":29,"featured_media":19377,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[24],"tags":[],"class_list":["post-19376","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-impact","issue-winter-2024"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.7 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Solving the Mystery of Blood Falls - JHU Engineering Magazine<\/title>\n<meta name=\"description\" content=\"Unlocking the mystery of Antarctica&#039;s Blood Falls, scientist Thomas Griffith Taylor&#039;s 1911 discovery, Ken Livi and a collaborative team, including microbiologist Jill A.
