What information is retained in a memory over time, and which parts get lost? These questions have led to many scientific theories over the years, and now a team of researchers at the Universities of Glasgow and Birmingham have been able to provide some answers.
Their new study, which is published today in
Nature Communications, demonstrates that our memories become less vibrant and detailed over time, with only the central gist eventually preserved. Moreover, this gistification of our memories is boosted when we frequently recall our recent experiences.
The work could have implications in a number of areas, including the nature of memories in post-traumatic stress disorder, the repeated questioning of eye-witness testimonies and even in best practice for exam studying.

A new COVID-19 test that reduces testing time from 30 minutes to less than five and delivers accurate results has been developed by researchers at the University of Birmingham.
The researchers believe their method could deliver a test that is not only fast but also sufficiently sensitive. The test does not require samples to be treated at high temperatures, and it can be performed using standard laboratory equipment, making it readily deployable.
A preprint paper (yet to be peer reviewed) describing the new process has been published on MedRxiv in which the researchers demonstrate the rapidity and sensitivity of their method using patient sample RNA provided by Public Health England.
