Adaptive valuation of social images by Rhesus Macaques
In a finding that deepens our understanding of animal social cognition, researchers at Duke University Medical Center have demonstrated for the first time that monkeys, like humans, value information according to its social content. People readily pay to see powerful or sexually attractive individuals, and, according to this new study, monkeys will also "pay" to view these kinds of images.
Both economics and evolutionary theory predict that animals should selectively acquire information about others that is most useful for guiding behavior. In most monkey social groups, behavior is structured by kinship, dominance, and reproductive status, suggesting that social information should be valued according to these attributes. While previous studies had shown that monkeys would work to see other monkeys, no one knew whether the value they placed on seeing other individuals was related to the social relevance of those individuals.

University of Connecticut researchers have created a biodegradable composite made of silk fibers that can be used to repair broken load-bearing bones without the complications sometimes presented by other materials.
Repairing major load-bearing bones such as those in the leg can be a long and uncomfortable process.
Study published in the journal ACS Applied Materials & Interfaces is the outcome of an international effort that included teams from Dresden and Berlin in Germany, and the US.
Scientists at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) together with colleagues from the Helmholtz-Zentrum Berlin (HZB) and the University of Virginia...
Novel highly efficient and brilliant gamma-ray source: Based on model calculations, physicists of the Max PIanck Institute for Nuclear Physics in Heidelberg propose a novel method for an efficient high-brilliance gamma-ray source. A giant collimated gamma-ray pulse is generated from the interaction of a dense ultra-relativistic electron beam with a thin solid conductor. Energetic gamma-rays are copiously produced as the electron beam splits into filaments while propagating across the conductor. The resulting gamma-ray energy and flux enable novel experiments in nuclear and fundamental physics.
The typical wavelength of light interacting with an object of the microcosm scales with the size of this object. For atoms, this ranges from visible light to...
Stable joint cartilage can be produced from adult stem cells originating from bone marrow. This is made possible by inducing specific molecular processes occurring during embryonic cartilage formation, as researchers from the University and University Hospital of Basel report in the scientific journal PNAS.
Certain mesenchymal stem/stromal cells from the bone marrow of adults are considered extremely promising for skeletal tissue regeneration. These adult stem...
