Four of the most widespread environmental toxins--lead, trihalomethanes (found in drinking water), ionizing radiation from indoor radon gas, and tobacco smoke--can cause serious damage to health even at very low levels, say researchers in the international medical journal PLoS Medicine.
What this means, say the researchers Donald Wigle of the University of Ottawa and Bruce Lanphear of Cincinnati Children’s Hospital Medical Center, is that there are simply no safe levels of exposure to these toxins and they must be "virtually eliminated to protect human health."
Children can suffer brain damage from being exposed to very low levels of lead, they say. Although the US Centers for Disease Control and Prevention does not recommend public health or medical action unless the blood lead level of children exceeds 0.48 micromoles/liter, several longitudinal studies of children found inverse relationships between IQ and blood lead levels over a range extending below 0.48 micromoles/liter. These studies found no evidence of a "safe" threshold.

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...
