Mayo Clinic researchers have discovered a previously unknown mechanism by which the kidneys help maintain water balance in the body. This discovery could ultimately lead to better treatments for polycystic kidney disease (PKD) and other conditions. The study, led by Mayo Clinic nephrologist Dr. Fuad Chebib, clinical research journal. Scientists have long believed that the body’s ability to concentrate urine and avoid dehydration depends primarily on the hormone vasopressin. New research reveals that the kidneys also have another pathway to regulate water that functions independently of vasopressin. “The kidney’s ability to regulate water is one of the most fundamental processes…

Once viewed primarily as a fertility disorder, PCOS is being reframed as a systemic endocrine and metabolic disease, opening the door to earlier diagnosis, more accurate risk profiling, and more personalized care. Pathophysiology of PCOS/PMOS. PCOS/PMOS is a complex syndrome involving multiple feedback loops in the anterior pituitary gland, liver, pancreas, and ovaries, ultimately leading to a hyperandrogenic state. In the pituitary gland, LH is released in greater amounts than FSH and stimulates the membranous cells of the ovary to increase androgen production. Androgens then stimulate the pituitary gland to release LH and FSH. Increased androgens also act on the…

From gait speed and DNA methylation to AI scans and clinical texts, a major review maps how scientists measure aging and why the field needs stronger evidence before these tools can guide patient care. Distinction between CA and BA and progression of the epigenetic clock over multiple generations. (a) Chronological age reflects a fixed time scale, whereas biological age reflects cellular and physiological decline. (B) First generation clocks (Horvath, Hannum, etc.) were trained to predict chronological age. Second generation clocks (PhenoAge, GrimAge, etc.) focus on phenotypic health and mortality risk. Third generation clocks (such as DunedinPACE) measure the current rate…

A global modeling study has warned that increased aircraft NOx emissions could sharply increase the health burden on the aviation industry, despite the industry’s focus on carbon-neutral flight. Research: Impact of increasing aircraft emissions on global air quality and human health. Image credit: ChatGPT / OpenAI Researchers quantified the current and future global health impacts of aviation-related air pollution by modeling aircraft emissions under multiple scenarios and estimating the impact on mortality. This research was published as a “paper” in a journal Communication Earth and Environment The authors are Flávio DA Quadros, Rick Nelen, Mirjam Snellen, and Irene C. Dedoussi,…

A new review maps how microbial signals from the gut disrupt appetite control, insulin sensitivity, inflammation and pancreatic function, suggesting a more targeted future in the treatment of metabolic diseases. Article: The microbiota-gut-brain axis: new mechanisms and therapeutic frontiers in obesity and type 2 diabetes. Image credit: Kateryna Kon / Shutterstock Review research paper. Available as a journal press article npj biofilm and microbiome, describe how gut microbial messengers contribute to the pathophysiology of obesity and type 2 diabetes via the microbiota-gut-brain axis. background The microbiota-gut-brain axis is a bidirectional communication network between the gut microbiota and the central nervous…

A study led by the University of California, Riverside that included more than 3,200 emergency department (ED) patients across the United States found that although influenza vaccination awareness is widespread, most adults presenting to the emergency department are not up to date on their annual influenza vaccination. The survey results are Emergency Medicine Journalsuggesting that EDs may play an important role in increasing vaccination rates, especially among medically underserved populations. Led by Dr. Robert Rodriguez, professor of medicine at UCR, researchers surveyed 3,285 adult patients at 10 emergency departments in eight U.S. cities from April to December 2024. Almost all…

For traumatic brain injury (TBI) and certain brain diseases, it appears that risk may extend in both directions, according to a study published June 17, 2026. Neurology®Medical Journal of the American Academy of Neurology. Studies have shown that suffering a traumatic brain injury may increase your risk of developing stroke, dementia, epilepsy, or Parkinson’s disease. In this new study, researchers looked at older veterans who had recently suffered a traumatic brain injury to see if they were more likely to develop any of these symptoms compared to people without a recent traumatic brain injury. They found that older veterans who…

Amazon One Medical reported a security event that affected a “limited number” of patients in its senior care clinic business. On June 13, One Medical learned that an unauthorized person had accessed a third-party file storage system used to maintain archival information for Iora Health, a company One Medical acquired in 2021, One Medical confirmed to Fierce Healthcare in a statement. Iora Health rebranded in 2023 and now operates as One Medical Senior Health. The company did not disclose how many One Medical Senior patients were affected or the total number of patients the senior care clinic currently serves. “We…

After infection, the Ebola virus can survive undetected in the human body for months or even years, hiding in areas with little immune surveillance, such as the central nervous system. Doing so risks causing a recurrence of Ebola hemorrhagic fever or a new epidemic. Researchers at the Icahn School of Medicine at Mount Sinai and the Bernhard Nocht Institute for Tropical Medicine (BNITM), along with other collaborators, used a brain organoid model to gain valuable insight into the persistence mechanisms of the Ebola virus. The results of this research have recently natural microbiology. Ebola virus is a filovirus that causes…

Gonorrhea is the second most commonly reported sexually transmitted infection (STI), with tens of millions of cases annually. In the United States alone, more than 600,000 cases are reported each year. If gonorrhea is left untreated, it can lead to severe reproductive health problems such as infertility and pelvic inflammatory disease in both women and men. Infection also increases the risk of HIV infection, and if the pathogen spreads from the genitals and throat to other parts of the body, it can damage the heart and cause meningitis and sepsis. The main challenge in controlling the disease more effectively lies…
