Scientists may have discovered a way to make us forget bad memories

Researchers at Cambridge University have discovered a protein in the brain of mice that may act as a biomarker for malleable memories. In other words, they may be able to determine which memories we can erase and which we are, for whatever reason, stuck with. Up front: The researchers conditioned laboratory mice by simultaneously shocking them and making a clicking noise.
