Imagine opening a book that tells the story of a hidden city within your own home that you never knew existed. That's what scientists from Stanford University have done with the discovery of (sidenote: Obelisks Newly discovered virus-like entities found within the bacteria of the human mouth and gut. Characterized by their unique RNA structures, these entities challenge traditional understandings of microbial and viral life forms. ) , a newly identified type of virus-like particles living inside the bacteria of our mouths and guts.
Like uncovering an ancient relic, the researchers used advanced genetic tools to map out the DNA landscapes of these bacteria, revealing that "Obelisks" dwell in about 7% of gut bacteria and an astonishing 50% of oral bacteria. This breakthrough not only shifts our view of the tiny life forms residing within us but also hints at rewriting the rules on how we understand viruses and the intricate ecosystems of our body's microbiome.
How were "Obelisks" discovered?
The research team employed a cutting-edge technique known as whole metagenome sequencing to analyze the genetic material from mouth and gut bacteria samples. This method allows scientists to read and compare the DNA sequences present, providing a comprehensive overview of the microbial landscape. By leveraging sophisticated bioinformatics tools, researchers identified these "Obelisks", which are characterized by their circular RNA genomes and unique rod-like structures.
One intriguing aspect of "Obelisks" is their RNA-based genome. RNA, or ribonucleic acid, is a molecule similar to DNA and is crucial for various biological roles, including acting as a messenger carrying instructions from DNA for controlling the synthesis of proteins. Unlike most organisms that store genetic information in DNA, these entities use RNA, which adds another layer of complexity to their nature.
Microorganisms: key for human health
What can we do with this?
The presence of "Obelisks" in such significant proportions within the human microbiome hints at their potential role in influencing our health, possibly affecting everything from digestion to immune responses. The study found that these entities could persist in individuals for over 300 days, suggesting they may have long-term effects on their hosts – Us!
The discovery of "Obelisks" not only opens new avenues for understanding the evolution of viruses but also sheds light on the intricate interactions within our microbiome. As researchers continue to unravel the mysteries of these RNA structures, this could lead to breakthroughs in treating diseases or manipulating the microbiome for better health outcomes.
