Researchers at the universities of Granada and Jaén, Spain, have discovered why recalling some items from memory reduces our ability to recall other related items.

We've all experienced it: The frustration of entering a room and forgetting what we were going to do. Or get. Or find.

A naturally occurring growth factor significantly boosted retention and prevented forgetting of a fear memory when injected into rats' memory circuitry during time-limited windows when memories become fragile and changeable.

According to a new study, the same brain lesions that are associated with dementia are responsible for mild memory loss in old age.

Scientists have known that newly acquired, short-term memories are often fleeting.
