Two-Step Blood Test Sharpens Alzheimer’s Diagnosis

Researchers have developed a two-step workflow using a new blood-based p-tau217 biomarker to improve the accuracy of Alzheimer's Disease (AD) diagnosis. The first step uses a diagnostic model that combines plasma p-tau217 with age and the APOE e4 gene to identify high-risk patients.

Educational Buffer: How Learning Slows Genetic Alzheimer’s Risk

Researchers examined the role of genetics and educational attainment in early-onset Alzheimer's disease, specifically focusing on carriers of the PSEN1 E280A mutation. They found that carriers with an additional high-risk mutation, APOE e4, experienced faster cognitive decline, while those with a protective APOE e2 mutation had delayed onset.

Who’s to Blame? How We Perceive Responsibility in Human-AI Collaborations

Even when people view AI-based assistants merely as tools, they still assign partial responsibility to these systems for decisions made. The research investigated how participants perceived responsibility when a human driver used an AI-powered assistant versus a non-AI navigation instrument.
