Yerkes-based experiment confirms cultural transmission and conformity in chimpanzee communities
Humans are not alone in their desire to conform to cultural norms, according to new study findings that confirm, for the first time, chimpanzees share the same conformist tendencies. Researchers, in determining how chimpanzee communities share and maintain traditions, discovered they possess a natural motivation to copy their peers well into adulthood and say that although other species show some cultural behaviors, the level of cultural variation shown by chimpanzees is exceeded only by humans. The study, conducted at the Yerkes National Primate Research Center of Emory University by a collaborative team of scientists from the United States and the United Kingdom, is published in the current online edition of Nature.
Unlike previous studies that used human models for cultural-learning experiments with chimpanzees, researchers Victoria Horner, PhD, and Frans B. M. de Waal, PhD, of the Living Links Center at the Yerkes Research Center, and Andrew Whiten, PhD, of the University of St. Andrews, Scotland, applied a unique method that extends the experimental approach to the group

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.
Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...
Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.
"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...
The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.
Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.
Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
