  • Mutation in one Parkinson’s protein eases cellular traffic jams caused by another
    on February 5, 2026 at 8:40 pm

    A hallmark of Parkinson’s disease is the buildup of Lewy bodies—misfolded clumps of the protein known as alpha-synuclein. Long before Lewy bodies form, alpha-synuclein can interfere with neurons’ ability to transport proteins and other cargo along their axons to the synapses. When present at high levels, alpha-synuclein binds too tightly to structures inside the axon, creating the cellular equivalent of traffic jams. These disruptions may even help set the stage for the later accumulation of Lewy bodies in the brain.

  • Study identifies key predictors for chronic opioid use following surgery
    on February 5, 2026 at 8:40 pm

    For many Americans, a routine surgical procedure serves as their first introduction to opioid pain medication. While most stop using these drugs as they heal, a considerable number of “opioid-naïve” patients transition into new persistent opioid use (NPOU)—continuing use long after the typical recovery period.

  • Novo Nordisk vows legal action to protect Wegovy pill

    Novo Nordisk said Thursday it would take legal action against a US chain offering a copycat of the new pill version of its Wegovy weight-loss drug.

  • How research sheds light on the invisible symptoms of MS
    on February 5, 2026 at 8:18 pm

    What are the often invisible cognitive consequences of multiple sclerosis? Maureen van Dam mapped these out during her doctoral research. “People usually notice the physical symptoms, but the cognitive symptoms deserve at least as much attention.” For Van Dam, the interest in the cognitive problems associated with multiple sclerosis (MS) started during her master’s internship.

  • 4D-printed vascular stent deploys at body temperature, eliminating external heating
    on February 5, 2026 at 8:04 pm

    Next-generation vascular stents can make cardiovascular therapies minimally invasive and vascular treatments safe and less burdensome. In a new advancement, researchers from Japan and China have successfully proposed a novel adaptive 4D-printed vascular stent based on shape-memory polymer composite. The stent exhibits mechanical flexibility, radial strength, biomechanical compliance, and cytocompatibility in in vitro and in vivo experiments, making them promising for future clinical applications.
