Harvard Center for Risk Analysis explores this issue
Fish has been a staple of human nutrition in many cultures, but there has been some controversy recently about the benefits and risks of fish consumption. For example, fish supplies polyunsaturated fatty acids (PUFAs), substances that might protect against coronary heart disease (CHD) and stroke. On the other hand, fish supplies methyl mercury (MeHg), a compound implicated in impairment of cognitive development and IQ. How can the consumer decide whether to increase or decrease consumption? What steps should governments, public health authorities and commercial fishing industries take in response to these conflicting facts?
Joshua T. Cohen, PhD, of the Harvard School of Public Health, writes, "Because fish consumption confers both benefits and risks, the advisories issued by the U.S. federal government raise the possibility of a classic risk–risk trade-off: by avoiding one risk (exposure to MeHg), consumers who follow these advisories may be incurring another (adverse health consequences associated with lower n-3 PUFA intake). Likewise, individuals who increase their consumption of fish because of this foods nutritional benefits may incur risks associated with MeHg exposure."

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...
