    In 1799, the famous German geologist Alexander von Humboldt wrote: "Science can only be advanced by combining all the phenomena on the earth
    .


    Rather than discovering new isolated facts, I prefer to connect known facts.



    Over the years, researchers have tried to combine geology, biology, medicine and cutting-edge microscope technology to explore the secrets of kidney stone formation
    .




    Kidney stones are deposits in the urinary system that affect more than 12% of people worldwide.


    The symptoms range from mild discomfort to severe pain.
    Complications can lead to death



    Although painful, the beauty of this stone is beyond many people's imagination
    .


    When scientists observed the cross-section of kidney stones, they found that some of them were very beautiful, some resembled crystal holes, and some resembled tree rings



    Professor Bruce Fouke is a geologist at the University of Illinois Urbana-Champaign.


    He is leading the team to apply the experience and methods of studying earth deposition to the study of kidney stones



    Recently, this research team collaborated with researchers from Mayo Clinic to publish a paper in Nature Reviews Urology under the umbrella of Nature, detailing the various stages of the kidney stone deposition process.


    And recorded by high-resolution imaging technology



    Kidney stones are formed in the same way as geological stones in nature
    .


    Previously, doctors thought that kidney stones were formed all at once.
    However, the analysis results obtained by Professor Fouke from geology are on the contrary.
    Kidney stones are not completely crystallized and deposited at one time, but undergo a process of partial dissolution and reconstruction for many times



    "When we identify these crystal phase transformations, what makes it from one step to the next and how it progresses, then maybe we can break the chain of chemical reactions that occur within the kidney tissue, thereby Intervene in this progress before the stone
    becomes problematic," said Dr.


    Mayandi Sivaguru, the first author of the study


    A particularly illuminating discovery was in the initial stage of kidney stone formation: at the beginning, the stones were just small round mineral microspheres (microspherules), similar to the small spheres formed by agate in natural volcanic rock sediments
    .


    These mineral microspheres then fuse in the kidney tissue and form larger, perfect geometric crystals
    .
    Under normal circumstances, these tiny mineral deposits are excreted from the body, but when they grow too fast and continue to form larger stones, they cannot leave the kidneys, causing human pain and even fatal in some cases
    .


    Researchers have found that at least 50% of the volume of stones has naturally undergone multiple cycles of partial dissolution and recrystallization, forming an iconic layered crystal pattern, which is very similar to agate, coral skeleton and hot spring sediments.

    .


    "Looking at the cross-section of a kidney stone, you would never guess that each layer was originally formed by a bunch of small balls arranged and fused
    .
    This is a revolutionary new way for us to understand how these minerals grow in the kidneys.
    Preventing the growth of stones provides a specific drug target
    .
    " said Professor Bruce Fouke, the corresponding author of the paper
    .


    After understanding the process of kidney stone formation, the study authors outlined several possible clinical interventions and treatment goals, from drug targets to changes in diet or supplements, which may disrupt the chemical and biological cascades that drive kidney stone formation
    .
    They hope that biological researchers and clinicians will be able to explore and test these options
    .


    In order to test, the research team also developed a microfluidic detection box called "GeoBioCell" designed to simulate the intricate internal structure of the kidney
    .
    The team hopes that the device will not only accelerate research, but also accelerate the evaluation of clinical diagnostic tests and potential therapies, especially for more than 70% of patients with recurrence of kidney stones
    .
