  • Cavities and gum disease could nearly double stroke risk
    on October 27, 2025 at 2:18 pm

    People with both cavities and gum disease were found to have an 86% higher stroke risk than those with healthy mouths. The study followed thousands of adults for two decades, linking poor oral health with major cardiovascular events. Regular dental checkups dramatically reduced these risks, hinting that simple oral care could play a vital role in stroke prevention.

  • Scientists launch $14.2 million project to map the body’s “hidden sixth sense”
    on October 25, 2025 at 3:17 pm

    Inside your body, an intricate communication network constantly monitors breathing, heart rate, digestion, and immune function — a hidden “sixth sense” called interoception. Now, Nobel laureate Ardem Patapoutian and a team at Scripps Research and the Allen Institute have received $14.2 million from the NIH to map this internal sensory system in unprecedented detail.

  • Scientists just found the lung’s hidden self-healing switch
    on October 25, 2025 at 3:45 am

    Researchers uncovered how lung cells decide whether to rebuild tissue or fight infection. This built-in “switch” may be the key to restoring the lungs’ natural repair ability. The discovery could lead to regenerative treatments for chronic lung diseases and faster recovery after injury.

  • Scientists finally see what sparks Parkinson’s
    on October 24, 2025 at 2:58 pm

    Researchers have finally seen and measured the tiny alpha-synuclein oligomers that may ignite Parkinson’s disease. With the ultra-sensitive ASA-PD imaging method, they captured these clusters in brain tissue, finding larger and more numerous versions in patients with Parkinson’s. The discovery could mark a turning point in diagnosing and treating the disease, revealing the first visible signs long before symptoms appear.

  • Scientists reversed brain aging and memory loss in mice
    on October 23, 2025 at 2:52 pm

    Cedars-Sinai researchers created “young” immune cells from human stem cells that reversed cognitive decline and Alzheimer’s symptoms in mice. The treated animals showed better memory and healthier brain structures. The cells seemed to protect the brain indirectly, possibly through anti-aging signals in the blood. The findings suggest a new, personalized path to slowing brain aging.

  • A “toxic duo” may be the hidden trigger behind Alzheimer’s disease
    on October 22, 2025 at 1:19 pm

    Scientists have uncovered a toxic alliance between Aβ and fibrinogen that may explain how Alzheimer’s disease begins. The two proteins together create stubborn clots that damage blood vessels and spark inflammation in the brain. These effects appear even at very low concentrations and disrupt the blood-brain barrier, paving the way for neurodegeneration. The findings highlight a potential new therapeutic target for early intervention.

  • Scientists discover how a high-fat keto diet could keep your brain young
    on October 21, 2025 at 3:59 pm

    Mizzou scientists are exploring how a ketogenic diet may protect the brain and prevent Alzheimer’s in people genetically predisposed to it. Their study found that female mice with the APOE4 gene benefited most, showing improved gut and brain health on a high-fat, low-carb diet. The findings highlight the value of personalized nutrition and early intervention to preserve cognition.

  • This simple innovation could change blood pressure testing forever
    on October 21, 2025 at 3:38 pm

    Scientists from the University of Exeter has developed a precise method to interpret ankle blood pressure readings—an innovation that could transform care for people unable to have their arm blood pressure measured. By analyzing data from over 33,000 participants, researchers created an algorithm and online calculator that improves accuracy and could prevent thousands of misdiagnoses worldwide.

  • Scientists reveal the best exercise to ease knee arthritis pain
    on October 20, 2025 at 8:28 am

    A sweeping review of over 200 studies finds that aerobic exercises like walking and cycling offer the best pain relief and mobility gains for knee osteoarthritis. Compared to other types of exercise, aerobic training showed the strongest evidence across short- and long-term outcomes. All forms of exercise were found to be safe, but experts recommend making aerobic activity the foundation of treatment.

  • These 80-year-olds have the memory of 50-year-olds. Scientists finally know why
    on October 19, 2025 at 1:45 pm

    SuperAgers defy normal aging by keeping sharp memories and healthy brains well into their 80s. Northwestern scientists discovered that these individuals either resist the buildup of harmful brain proteins or remain unaffected by them. Their brains stay structurally youthful, and their strong social lives may help protect cognition. The findings could inspire new ways to delay or prevent dementia.

  • Tiny brain nanotubes found by Johns Hopkins may spread Alzheimer’s
    on October 16, 2025 at 5:30 am

    Johns Hopkins scientists uncovered microscopic “nanotube” channels that neurons use to transfer toxic molecules. While this process clears waste, it can also spread harmful proteins like amyloid-beta. Alzheimer’s-model mice showed more nanotubes early on, hinting at a link to disease development. Researchers hope to one day control nanotube formation as a potential therapy.

  • This European treatment for joint pain just passed a major scientific test
    on October 15, 2025 at 2:46 pm

    Korean researchers found that low-dose radiation therapy eased knee pain and improved movement in people with mild to moderate osteoarthritis. The treatment, far weaker than cancer radiation, showed real benefits beyond placebo. With no side effects and strong trial results, the approach could provide a middle ground between painkillers and joint surgery.

  • Supercharged vitamin k could help the brain heal itself
    on October 14, 2025 at 3:08 pm

    Researchers have synthesized enhanced vitamin K analogues that outperform natural vitamin K in promoting neuron growth. The new compounds, which combine vitamin K with retinoic acid, activate the mGluR1 receptor to drive neurogenesis. They also efficiently cross the blood-brain barrier and show stability in vivo. This discovery could pave the way for regenerative treatments for Alzheimer’s and related diseases.

  • Scientists find the brain’s hidden pulse that may predict Alzheimer’s
    on October 14, 2025 at 2:24 pm

    Researchers at USC have created the first method to noninvasively measure microscopic blood vessel pulses in the human brain. Using advanced 7T MRI, they found these tiny pulsations grow stronger with age and vascular risk, disrupting the brain’s waste-clearing systems. The discovery may explain how circulation changes contribute to Alzheimer’s and other neurodegenerative diseases.

  • C-section births linked to sleepless nights and painful recoveries
    on October 13, 2025 at 3:36 pm

    Women who undergo C-sections are more likely to experience debilitating pain and sleep disorders in the months after giving birth. Researchers found both qualitative and large-scale data supporting this link, including a 16% increase in sleep disorder diagnoses. Proper pain management and healthy sleep habits can reduce these risks, helping new mothers recover more smoothly and avoid complications like depression and fatigue.
