This incredibly ancient rock was not only habitable but still contained living microbes within its \u201csealed fractures,\u201d as per a recent press release. <\/p>\n<p>\u201cIt is the oldest example of living microbes being found within ancient rock so far discovered,\u201d it said.<\/p>\n<p>Remarkably, these ancient life forms could hold the key to understanding life in the far reaches of the universe, particularly in rock samples retrieved from Mars. The search for extraterrestrial life continues, and this discovery fuels our curiosity.<\/p>\n<\/div>\n<\/div>\n<div>\n<div>\n<p>\u201cBy studying the DNA and genomes of microbes like these, we may be able to understand the evolution of very early life on Earth,\u201d Yohey Suzuki, lead author from the University of Tokyo, said.<\/p>\n<h2 class=\"wp-block-heading\" id=\"h-analyzing-2-billion-year-old-rock\">Analyzing 2-billion-year-old rock<\/h2>\n<p>In a new study published in <em>Microbial Ecology<\/em>, microbiologists focused their research on the Bushveld Igneous Complex in northeastern South Africa. This geological formation originated from magma cooling beneath the Earth\u2019s surface and is renowned for its abundant ore deposits, including 70% of the world\u2019s mined platinum.<\/p>\n<p>The immense age of this geological wonder intrigued the researchers from the University of Tokyo. They were uncertain if the 2-billion-year-old rock could harbor life and embarked on a mission to uncover the truth.<\/p>\n<p>To conduct this revolutionary work, the team had to perfect a technique involving three types of imaging: infrared spectroscopy, electron microscopy, and fluorescent microscopy. Their first step was to obtain a sample.<\/p>\n<\/div>\n<\/div>\n<div>\n<div>\n<p>Drilling 15 meters or 49 feet into the ground, they retrieved a 30-centimeter-long rock sample. To prevent contamination, Suzuki drew inspiration from the techniques pathologists use to prepare thin tissue samples for disease diagnosis, building on his previous work where his team discovered microbes in rock beneath the seafloor. <\/p>\n<p>He coated the rock in \u201ca special epoxy\u201d to prevent it from crumbling during slicing. Then, he washed the thin sections in a special dye that stained the DNA of the microbial cells. Using infrared spectroscopy, a chemical analysis technique, they discovered that the microbes were densely packed within the cracks. The surrounding clay had prevented them from spreading or interacting with other substances.<\/p>\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1920\" height=\"1080\" src=\"https:\/\/cms.interestingengineering.com\/wp-content\/uploads\/2024\/10\/400248200-1.png\" alt=\"\" class=\"wp-image-110062\" srcset=\"https:\/\/cms.interestingengineering.com\/wp-content\/uploads\/2024\/10\/400248200-1.png 1920w, https:\/\/cms.interestingengineering.com\/wp-content\/uploads\/2024\/10\/400248200-1.png?resize=300,169 300w, https:\/\/cms.interestingengineering.com\/wp-content\/uploads\/2024\/10\/400248200-1.png?resize=768,432 768w, https:\/\/cms.interestingengineering.com\/wp-content\/uploads\/2024\/10\/400248200-1.png?resize=1536,864 1536w\" sizes=\"auto, (max-width: 1920px) 100vw, 1920px\"\/><figcaption class=\"wp-element-caption\">The Bushveld Igneous Complex (BIC), South Africa.\u00a0<a href=\"https:\/\/www.u-tokyo.ac.jp\/focus\/en\/press\/z0508_00374.html\" target=\"_blank\" rel=\"noopener noreferrer\">Y.
