Episode notes

The brain creates three distinct copies of each memory, according to recent research. Utilizing advanced imaging techniques, the study identified that early-born neurons generate a long-lasting memory that strengthens over time, supporting long-term memory persistence and resistance to change. Late-born neurons produce a strong yet fleeting memory, allowing for easier modification. In contrast, intermediate neurons yield a stable copy that remains consistent. This triplicate system fosters both memory persistence and flexibility, with early-born neurons aiding retrieval of distant memories and late-born neurons allowing integration of recent information. This innovative model reflects the brain's extensive storage capacity and adaptability, which could inform new treatments for memory disorders like Alzheimer's and therapeutic strategies for managing intrusive memories in PTSD.

Today's Discover Daily episode begins with a look at the impact of Mastercard's transition away from magnetic strips technology. This shift towards EMV chip technology promises enhanced security and will significantly impact various sectors of the payment ecosystem.

Then, a new study shows how long term and short term memory actual works: our brain create three distinct copies of every memory, each serving a unique purpose in memory formation and recall. We explain how this actual works and what it could mean for memory disorders.

Our final story focuses on a lesser known, computer animation pioneer: Alvy Ray Smith. Smith co-founded Pixar and stood up to Steve Jobs in a dramatic confrontation. His contributions to computer graphics and animation continue to shape the industry, despite being overshadowed by Jobs' larger-than-life persona.
