Alzheimer’s mystery cracked! Scientists used AI to reveal that a gene called PHGDH isn’t just a biomarker—it actually causes the disease by messing with how brain genes turn on and off. Even wilder: they found a small molecule, NCT-503, that blocks this sneaky gene’s harmful side hustle without messing up normal brain function. Mice treated with it got their memory and chill back. Could this be the breakthrough we’ve been waiting for? #Alzheimers #AI #MedicalBreakthrough #BrainHealth #ScienceNews #Health
