Subtle patterns of brain activity can predict a person's risk of developing Alzheimer’s disease years before symptoms emerge or harmful proteins accumulate, according to a Stanford Medicine study published in Science Advances. Researchers developed a scoring system based on differences in brain communication observed between Alzheimer’s patients aged 75 and older and "super agers," whose memory capabilities match those of people decades younger. When applied to cognitively healthy adults between the ages of 55 and…

- Summary:
- Stanford researchers have discovered that hidden patterns of brain activity can predict Alzheimer’s risk years before memory problems appear, potentially offering an earlier warning than traditional biomarkers. The same patterns also reveal which brains are unusually resistant to aging, raising hopes for future treatments that could help protect memory.

Subtle patterns of brain activity may reveal the risk of Alzheimer's disease years before memory problems develop or harmful proteins begin accumulating in the brain, according to new research led by Stanford Medicine. The same approach can also identify people whose brains show exceptional resistance to cognitive decline, suggesting they may eventually become "super agers."
The study, published November 4 in Science Advances, points to a potentially powerful new way to detect early warning signs of cognitive decline. Unlike conventional biomarkers, these patterns of brain activity might eventually be possible to change through targeted interventions.
To investigate, the research team examined brain activity in adults aged 75 and older who represented opposite ends of the…
Scientists aim to turn hazardous municipal incineration residues into valuable construction aggregates that permanently lock away greenhouse gases. By substituting traditional materials, the initiative targets lower industrial emissions while providing a circular solution for millions of tonnes of contaminated refuse. The multi-institution effort focuses on balancing processing energy demands against maximum carbon uptake to establish a commercially viable mineral recycling pathway.
Researchers at The Ohio State University quantified early childhood language exposure by evaluating the vocabulary found in commonly circulated library books. The investigation revealed that regular shared literature introduces unique settings and vocabulary absent from routine household discussions, significantly shaping classroom readiness before school begins. Furthermore, researchers noted the actual language disparity could be even greater because parents routinely converse outside the written text during sto…
Despite systemic gender barriers in academia and government, Mary Engle Pennington pioneered scientific cold-storage standards that protected the nation's perishable food supply. Her bacteriological research into milk and poultry preservation provided the practical framework needed to enforce the Pure Food and Drugs Act of 1906. Pennington's findings fundamentally modernized agricultural transportation and commercial food handling across the United States.
