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.

Satellites in near-Earth orbit are at risk due to the steady increase in space debris. But their mission in the areas of telecommunications, navigation or weather forecasts is essential for society. Fraunhofer FHR therefore develops radar-based systems which allow the detection, tracking and cataloging of even the smallest particles of debris. Satellite operators who have access to our data are in a better position to plan evasive maneuvers and prevent destructive collisions. From April, 25-29 2018, Fraunhofer FHR and its partners will exhibit the complementary radar systems TIRA and GESTRA as well as the latest radar techniques for space observation across three stands at the ILA Berlin.
The "traffic situation" in space is very tense: the Earth is currently being orbited not only by countless satellites but also by a large volume of space...
An international team of researchers has discovered a new anti-cancer protein. The protein, called LHPP, prevents the uncontrolled proliferation of cancer cells in the liver. The researchers led by Prof. Michael N. Hall from the Biozentrum, University of Basel, report in “Nature” that LHPP can also serve as a biomarker for the diagnosis and prognosis of liver cancer.
The incidence of liver cancer, also known as hepatocellular carcinoma, is steadily increasing. In the last twenty years, the number of cases has almost doubled...
In just a few weeks from now, the Chinese space station Tiangong-1 will re-enter the Earth's atmosphere where it will to a large extent burn up. It is possible that some debris will reach the Earth's surface. Tiangong-1 is orbiting the Earth uncontrolled at a speed of approx. 29,000 km/h.Currently the prognosis relating to the time of impact currently lies within a window of several days. The scientists at Fraunhofer FHR have already been monitoring Tiangong-1 for a number of weeks with their TIRA system, one of the most powerful space observation radars in the world, with a view to supporting the German Space Situational Awareness Center and the ESA with their re-entry forecasts.
Following the loss of radio contact with Tiangong-1 in 2016 and due to the low orbital height, it is now inevitable that the Chinese space station will...
