Ever catch a glimpse of someone but cant quite fit a name to go with the face? While its something that happens to everyone, for older people especially, difficulty in retrieving names is a common frustration.
Scientists at the University of Arizona in Tucson are trying to determine what goes on inside the brain when it sees a face. How, for instance, does the brain recognize faces and retrieve the names to go with them? Also, how does the brain determine whether the information that it has retrieved is accurate? "In other words, how do we know when we come up with a possible memory that its the right one, as opposed to something we dreamt or imagined," said Alfred Kaszniak, one of the authors of the study.
The lead author of the study, "Feeling of Knowing for Faces: An fMRI Study," Jasmeet Pannu, is a graduate student at the University of Arizona in Tucson. Steven Rapcsak, a UA associate professor of neurology and a behavioral neurologist at the Veterans Medical Center in Tucson, and Kaszniak, a professor and head of the psychology department at the UA, are the other authors. Their latest research is being presented at the annual Society for Neuroscience meeting in San Diego.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales
Studying properties of fundamental particles in condensed matter systems is a promising approach to quantum field theory. Quasiparticles offer the opportunity...
Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
