The best strategy for minimizing future influenza morbidity and mortality would be to concentrate vaccinations in school children and high-risk groups, according to a new research commentary by scientists at Emory University. The alternative vaccine plan is based on mathematical models developed by Ira Longini, PhD, and Elizabeth Halloran, MD, DSc, professors of biostatistics in Emorys Rollins School of Public Health, and on influenza field studies. The report will be published in the February 15 issue of The American Journal of Epidemiology.
The mathematical models show that vaccinating about 70 percent of school children, ages 6 to 18, with influenza vaccine would reduce community-wide transmission to very low levels. School children are the population group generally most responsible for transmission of influenza because of more exposure potential and less prior immunity than adults. Even if only 50 percent of school children could be vaccinated, this would still result in a considerable reduction in transmission within the community, according to the models. The vaccine strategy over the last several years has been based on distributing vaccine primarily to high-risk groups, and such a strategy has not been very effective in reducing influenza deaths and illness, the researchers assert. Due to the current vaccine shortage, this same strategy has been enacted with the further stipulation that vaccine be limited to high risk and other predefined groups, but not to low risk school children.
The researchers suggest that the alternative strategy of vaccinating children and high risk groups would require around 120 million doses of vaccine per season, taking into account the fact that many high-risk people are never vaccinated. They recommend that the federal government guarantee the purchase and distribution of that many doses of vaccine each year in order to stabilize production. This strategy not only would be effective for normal yearly flu outbreaks, but also for years of pandemic influenza when supplies of vaccine are more limited.

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...
