Scientists Use CRISPR to Delete Fearful Memories in Rats

Researchers at Peking University have used CRISPR gene editing to remove fearful memories from rats. The new technique could be used to treat pathological memories and memory-related conditions such as PTSD, drug addiction, chronic pain, and chronic stress. While negative memories could be essential for survival, too much focus on them can cause psychological and physical disorders. The study isn't clear on how memories are targeted and what safety measures are used to ensure other memories aren't accidentally removed.
