Superagers aged 80 years and older demonstrate a unique neurobiological profile associated with successful aging: preserved memory and distinct brain anatomy, including thicker cortical regions and lower tau pathology.
Estradiol increases susceptibility to retinal degeneration in female mice with retinitis pigmentosa, highlighting hormone-specific effects on neurodegenerative disease pathways.
Researchers visualize how insulin travels from the nose to the brain using PET scans, uncovering differences in uptake based on cognition, blood pressure, and sex.
As neurotech devices move from clinics to consumers, states are racing to safeguard brainwave data from earbuds, sleep trackers, and AI-powered apps—raising new questions about privacy, consent, and medical ethics.
Researchers used blood proteins to estimate the biological age of 11 organs in over 44,000 people, revealing that older brain and immune systems were linked to higher disease and death risks, while younger ones predicted longer life.
