Boosting Wnt Signaling Reverses APOE4 Alzheimer’s Damage

Summary: MIT neuroscientists discovered that the APOE4 gene variant suppresses critical Wnt signaling in oligodendrocytes, trapping essential fatty acids inside toxic lipid droplets rather than deploying them as protective myelin…

Aging Brains Maintain Robust Language Networks Despite Cognitive Decline

Summary: While executive functions like memory and problem-solving naturally decline as we age, new brain imaging research reveals that the neural network responsible for language remains preserved and fully functional.…
