New research has found that the brain continues to accept ambiguous visual information about an object in motion even when it conflicts with more reliable information that we can touch. The studies, which appear in the June 7 issue of the journal Psychological Science and the forthcoming June issue of the journal Cognitive, Affective, & Behavioral Neuroscience, provide new insights into the way the brain blends and balances information from different senses.

The research, conducted by Vanderbilt psychologists Randolph Blake, Centennial Professor of Psychology, and Thomas W. James and Kenith V. Sobel, research associates, found that the region of the brain that specializes in processing visual movement-the middle temporal visual center, or MT-also responds to motion that we feel. But they were surprised to discover that when individuals were presented with an ambiguous visual image and were able to touch that object, their brains did not fuse the visual and touch inputs into a single, accurate representation. Instead, the researchers found that the brain keeps the two inputs separate and accepts a degree of "cognitive dissonance" when the two conflict.
"This suggests that there is naturally a higher level of inconsistency between seeing and feeling something moving than there is between seeing and feeling somethings shape," says James.

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...

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...
