Scientists at Northern Arizona University are developing a non-invasive blood test that could help detect Alzheimer’s disease before symptoms appear by examining how the brain uses glucose through tiny blood-borne microvesicles. Led by assistant professor Travis Gibbons and supported in part by the Arizona Alzheimer’s Association, the project aims to enable earlier diagnosis and intervention, similar to how doctors manage cardiovascular disease.
Adults age 65 and older who consume eggs regularly face a reduced chance of developing Alzheimer’s disease, according to new research from Loma Linda University Health. The study found that eating at least five eggs per week was associated with up to a 27 percent lower risk. Even modest intake showed measurable benefits.

Researchers at UNSW Sydney have identified around 150 functional DNA enhancers in human astrocytes that regulate genes associated with Alzheimer's disease. By testing nearly 1,000 potential switches using advanced genetic tools, the team revealed how non-coding DNA influences brain cell activity. The findings, published on December 18 in Nature Neuroscience, could aid in developing targeted therapies and improving AI predictions of gene control.
