• A tire chemical called 6PPD-Q, already blamed for killing salmon, was examined for possible links to Alzheimer’s disease in a new computer-based study.
  • Using computer models, researchers found that the chemical can latch onto several proteins associated with Alzheimer’s and reach brain regions involved in the disease.
  • No patients or animals were tested; the study rests entirely on computer predictions and reused datasets, so it cannot prove the chemical causes Alzheimer’s.
