Region once slated for logging supports tool-making chimps
Scientists have discovered that a remote rainforest in Central Africa, saved from logging by a collaboration among the New York-based Wildlife Conservation Society, a timber company and the Republic of Congo, is home to a population of innovative, tool-making chimpanzees that "fish" for termite dinners. According to a study in the November issue of the journal The American Naturalist, chimps living in the 100-square-mile "Goualougo Triangle" have given researchers a comprehensive snapshot of more complex tool-use among non-human large primates.
Though earlier studies have documented tool use among chimps in eastern Africa and other regions, authors Crickette Sanz of Max Planck Institute for Evolutionary Anthropology, WCS researcher David Morgan of Cambridge University, and Steve Gulick of Wildland Security say that the Goualougo chimps use tools in different ways than previously observed. The study, funded in large part by WCS and National Geographic, relied on remote video cameras recording chimps using heavy sticks to punch holes in termite mounds, then using a lighter stick known as a "fishing tool" to extract termites. For underground termite mounds a different stick-tool was used to perforate the nest surface, before scooping up the termites.

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.
The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".
Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
