    Meniscus injuries may soon be treated by customizable hydrogel

    Meniscus tears are common knee injuries that have long frustrated patients and doctors due to limited repair options.A new 3D-printed hydrogel made from cow meniscus could transform how these injuries heal, according to results of a pre-clinical study published in Bioactive Materials. from researchers in the Perelman School of Medicine at the University of Pennsylvania.

    The meniscus is a complex structure that serves as a critical shock absorber in the knee. and one-size-fits-all treatments…

  • Cold plunges actually change your cells

    Cold plunges actually change your cells

    Ever wondered what happens to your body when you take those trendy ice baths? Scientists at the University of Ottawa just found out, and it’s pretty fascinating.

    A new study conducted at the Human and Environmental Physiology Research lab (HEPRU) at the University of Ottawa has unveiled significant findings on the effects of cold water acclimation on autophagic (the cells’ recycling system, which promotes cellular health) and apoptotic (the programmed cell death that gets rid of damaged…

  • Researchers develop new DNA test for personalized treatment of bacterial vaginosis

    Researchers develop new DNA test for personalized treatment of bacterial vaginosis

    Roughly one out of three women ages 14-49 in the United States develop a vaginal bacterial imbalance known as bacterial vaginosis (BV) during their lifetime. BV is characterized by unpleasant odors, and potentially painful side effects, as well as the risk of associated health issues later in life. More than half of the patients who seek medical care do not respond to the first-line treatment, the antibiotic metronidazole, leading to recurrence.

    Now Drexel researchers have developed a simple…

  • Brain channels ‘stopped in time’ reveal chemical flow that enables learning and thinking

    Brain channels ‘stopped in time’ reveal chemical flow that enables learning and thinking

    In an effort to understand how brain cells exchange chemical messages, scientists say they have successfully used a highly specialized microscope to capture more precise details of how one of the most common signaling molecules, glutamate, opens a channel and allows a flood of charged particles to enter. The finding, which resulted from a study led by Johns Hopkins Medicine researchers, could advance the development of new drugs that block or open such signaling channels to treat conditions…

  • ‘Everyday discrimination’ linked to increased anxiety and depression across all groups of Americans

    ‘Everyday discrimination’ linked to increased anxiety and depression across all groups of Americans

    People who most frequently encounter everyday discrimination – those subtle snubs and slights of everyday life – are more likely to suffer from anxiety and depression.

    What’s more, that finding remains true no matter the person’s race, gender, age, education, income, weight, language, immigration status or where they live.

    These are the key takeaways from our recent study, published in JAMA Network Open.

    Everyday discrimination refers to the routine ways people are treated…

  • New approach could treat anthrax beyond the ‘point of no return’

    New approach could treat anthrax beyond the ‘point of no return’

    Anthrax, an infectious disease caused by the bacterium Bacillus anthracis, is often treatable in its early stages. But once the disease has progressed beyond the “point of no return” after just a few days, patients are almost certainly doomed.

    In a new Nature Microbiologystudy, University of Pittsburgh researchers show that a cocktail of growth factors reversed would-be lethal cell damage in mice with anthrax, suggesting that this approach could be adapted for use in patients beyond the…

    AI meets oncology: New model personalizes bladder cancer treatment

    Leveraging the power of AI and machine learning technologies, researchers at Weill Cornell Medicine developed a more effective model for predicting how patients with muscle-invasive bladder cancer will respond to chemotherapy. The model harnesses whole-slide tumor imaging data and gene expression analyses in a way that outperforms previous models using a single data type.

    The study, published March 22 in npj Digital Medicine, identifies key genes and tumor characteristics that may determine…

    PET imaging confirms direct involvement of dopamine in cognitive flexibility

    For the first time, scientists have confirmed a neurobiochemical link between dopamine and cognitive flexibility, according to new research published in the March issue of The Journal of Nuclear Medicine. PET imaging shows that the brain increases dopamine production when completing cognitively demanding tasks, and that the more dopamine released, the more efficiently the tasks are completed. Armed with this information, physicians may soon be able to develop more precise treatment…

  • Understanding the immune response to a persistent pathogen

    Understanding the immune response to a persistent pathogen

    Most humans have long-lived infections in various tissues — including in the nervous system — that typically do not result in disease. The microbes associated with these infections enter a latent stage during which they quietly hide in cells, playing the long game to evade capture and ensure their own survival. But a lack of natural models to study these quiescent stages has led to gaps in scientists’ understanding of how latency contributes to pathogen persistence and whether these stages…
