British scientists are joining colleagues from around the world today (Thursday March 30th 2006) at Fermi National Accelerator Laboratory (Fermilab) in the USA to share the first results from a new neutrino experiment. The Main Injector Neutrino Oscillation Search (MINOS) is designed to study ghostly particles called neutrinos and in particular to study how the three different types are able to transform one into the other. In their first data release, the MINOS team has already reached the sensitivity of previous experiments and provides independent confirmation that neutrinos have mass.
Professor Jenny Thomas, from UCL, said "The first MINOS result is a totally independent confirmation of the surprising fact that neutrinos are not massless. It opens up a whole field of study to understand why this is true and what it means to our understanding of the universe."
Neutrinos are vital to our understanding of the Universe. Nature provides for three types of neutrinos, yet scientists know very little about these ghost particles, which can traverse the entire Earth without interacting with matter. But the abundance of neutrinos in the universe, produced by stars and nuclear processes, may explain how galaxies formed and why antimatter has disappeared. Originally neutrinos were thought to have no mass, but previous experiments suggested that they can oscillate between the three types - a phenomenon which is only possible if they do have mass.

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...
