Warnings about methylmercury contaminated fish are not just for young children and expectant mothers, according to new research published today in Environmental Health: A Global Access Science Source. Adults who regularly eat contaminated fish could find that their concentration, dexterity and verbal memory are impaired.
The major source of methylmercury is diet, particularly large fish like shark and swordfish. The authors of this new research concluded: "methylmercury exposure at levels often encountered by adults in North America may be inducing adverse effects on neurobehavioral performance."
Methylmercury damages or destroys nerve tissue. It affects the visual cortex and the cerebellum, the part of the brain responsible for controlling complex movements and maintaining balance. This new research challenges the assumption that adults are much less sensitive to its toxic effects than children.

Scientists at the Fraunhofer Institute for Laser Technology ILT have come up with a striking new addition to contact stamping technologies in the ERDF research project ScanCut. In collaboration with industry partners from North Rhine-Westphalia, the Aachen-based team of researchers developed a hybrid manufacturing process for the laser cutting of thin-walled metal strips. This new process makes it possible to fabricate even the tiniest details of contact parts in an eco-friendly, high-precision and efficient manner.

An international research team with Prof. Cornelia Denz from the Institute of Applied Physics at the University of Münster develop for the first time light fields using caustics that do not change during propagation. With the new method, the physicists cleverly exploit light structures that can be seen in rainbows or when light is transmitted through drinking glasses.
Modern applications as high resolution microsopy or micro- or nanoscale material processing require customized laser beams that do not change during...
