Turns out, the so-called 'junk' DNA in our brains might actually be packed with secret switches that help Alzheimer's take hold. Scientists found over 150 of these control signals in astrocytes—those brain helper cells that can turn from friend to foe in Alzheimer's. Using CRISPRi, they pinpointed which DNA switches mess with genes linked to the disease. This could be a game-changer for figuring out why brains go haywire and how to fix them! #Health #BodyHealth #Alzheimers
