Research led by Ian M. McDonough at Binghamton University finds that aging brains don't simply lose memories—they blend distinct memories together, causing interference rather than pure forgetting. The study suggests older adults' memory problems stem from reduced ability to keep similar memories separate, not just storage decay.

Why: For AI/ML practitioners designing memory or retrieval systems, this biological mechanism—blending similar memories rather than dropping them—offers a concrete analogy for debating whether agent memory architectures should use decay, deduplication, or similarity-based merging. No direct builder action required.
