Scientists have found a gene that wipes memories!

Although it's only been performed in lab mice so far, scientists have made a discovery that could lead to humans being able to wipe certain memories from their brain.

The gene is called Tet1, which they turned off in a group of mice. Then, they exposed the altered mice, and another group of normal mice to a cage with a shocking mechanism.

Both groups of mice learned to fear the cage. Scientists later turned off the shocking mechanism. One group eventually learned to not fear the cage anymore, while the other still feared it.

Scientists think amplifying the effects of Tet1 could lead to memories being completely replaced. This could eventually help people completely forget about the memories that cause their PTSD, for example.
