In the August issue of Current Directions in Psychological Science, a journal of the Association for Psychological Science, Boston College psychologist, Elizabeth Kensinger and colleagues, explain when emotion is likely to reduce our memory inconsistencies.
Her research shows that whether an event is pleasurable or aversive seems to be a critical determinant of the accuracy with which the event is remembered, with negative events being remembered in greater detail than positive ones.
For example, after seeing a man on a street holding a gun, people remember the gun vividly, but they forget the details of the street. Functional Magnetic Resonance Imaging (fMRI), studies have shown increased cellular activity in emotion-processing regions at the time that a negative event is experienced.
The more activity in the orbitofrontal cortex and the amygdala, two emotion-processing regions of the brain, the more likely an individual is to remember details intrinsically linked to the emotional aspect of the event, such as the exact appearance of the gun.
Kensinger argues that recognizing the effects of negative emotion on memory for detail may, at some point, save our lives by guiding our actions and allowing us to plan for similar future occurrences. “These benefits make sense within an evolutionary framework,” writes Kensinger. “It is logical that attention would be focused on potentially threatening information.”
This line of research has far-reaching implications in understanding autobiographical memory and assessing the validity of eyewitness testimony. Kensinger also believes that this research may end insight into the symptoms of posttraumatic stress disorder.

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
