Researchers have discovered that a parasite carried by an invasive species of minnow is responsible for the dramatic declines and localized extinctions of a different minnow species in Europe during the past 40 years.
This parasite, which scientists have found can almost totally destroy the spawning success of the small sunbleak minnow, Leucaspius delineatus, may pose threats to the diversity and stability of freshwater ecosystems, and is genetically very similar to a parasite that can be deadly to salmon, researchers say.
The findings were published today in the journal Nature by researchers from Oregon State University, the Winfrith Technology Centre in England, Idaho State University and the Weymouth Laboratory in England.

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...
