Whether its the look of love, happiness, or the look of fear, humans use facial expressions to communicate important information to one another. But which parts of the brain read these cues, and how do they do it? A paper in this weeks Nature by a group of international scientists, including Professor Philippe Schyns from the University of Glasgow, offers new insights into how we recognize fear in peoples eyes.
The study focuses on a case study of a 38-year-old woman with rare bilateral damage to her amygdala - an almond-shape part of the brain in the temporal lobe. Unusually, she is completely unable to recognize fear from facial expressions - this deficit though can be rescued by instructing her to concentrate her attention on the persons eyes. The researchers found, however, that the woman (named SM in the study) only succeeded in directing her gaze to the eye regions of facial images when given explicit reminders.
SM’s problem is that although she can physically see facial features, she can’t recognise the emotion of fear. SMs impairment stems from an inability to make normal use of information from the eye region within faces when judging emotions, although she can read emotions from the mouth. Her selective impairment in recognizing fear is explained by the fact that that the eyes are the most important feature for identifying fear. However, the subject’s recognition of fearful faces became entirely normal when she was instructed to look at the eyes.

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.
