Study by researchers from Syracuse University, Syracuse, N.Y., and Union College, Schenectady, N.Y., to be published in the Nov. 14 issue of Nature
El Niño, the pattern that can wreak havoc on climate conditions around the world, is like a beacon, pulsating through time on a 2,000 year cycle, according to a new study by scientists from Syracuse University, Syracuse, N.Y.; Union College, Schenectady, N.Y., and from the NOAA Paleoclimatology Program, Boulder, Colo., that is being published in the Nov. 14 issue of Nature.
The study, which resulted from a detailed analysis of a continuous 10,000-year record of El Niño events from a lake in southern Ecuador, is the first documented evidence that such a millennial cycle exists for El Niño. The researchers found that the frequency of El Niño events peaked about 1,200 years ago, or during the early Middle Ages. If the pattern continues into the future, there should be an increase in El Niño events in the early part of the 22nd century, the scientists say.

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...
