Virginia Tech researchers have shown that memory loss in aging may be reversible. Using CRISPR tools, they corrected molecular disruptions in the hippocampus and amygdala, restoring memory in older rats. Another experiment revived a silenced memory gene, IGF2, through targeted DNA methylation editing. These findings highlight that aging brains can regain function through precise molecular intervention.

"In mice", I thought to myself. But then I read the article - and how wrong I was!

Looking forward to seeing the same generation of biohackers who previously CRISPRed their lactose intolerance to now CRISPR their hippocampi!
