The evolution of the sense of fairness may have involved the quality of relationships according to behavioral researchers at the Yerkes National Primate Research Center in Atlanta.
By observing variability in chimpanzees responses to inequity, Sarah Brosnan, PhD, and Frans de Waal, PhD, both researchers in Yerkes Division of Psychobiology and the Yerkes-based Living Links Center, determined the chimpanzees responses depended upon the strength of their social connections. This is the first demonstration that nonhuman primates reactions to inequity parallel the variation in human responses to unfair situations based on the quality of the relationship. This novel finding appears January 26 on the Proceedings of the Royal Academy of Sciences, Series B web site, www.journals.royalsoc.ac.uk. The finding also will appear in the journals February 7 print edition.
Coupled with data from the authors previous fairness-related research in capuchin monkeys, released in fall 2003, Brosnan and de Waals current research provides new insight into the role social environment and relationships play in human decision-making. In their previous study, the researchers identified for the first time a sense of fairness in nonhuman primates and correlated that finding to human economic decision-making. "Human decisions tend to be emotional and vary depending on the other people involved," said Brosnan. "Our finding in chimpanzees implies this variability in response is adaptive and emphasizes there is not one best response for any given situation but rather it depends on the social environment at the time."

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...
