"There is no relationship between the level of exposure to MMR vaccines and thimerosal–containing vaccines and rates of autism," says Dr. Eric Fombonne, Director of Pediatric Psychiatry at The Montreal Children's Hospital of the MUHC and lead investigator of the new study. Thimerosal was used to prevent bacterial and fungal contamination in the manufacture of various vaccines until its elimination from vaccine formulas in 1996 in Quebec. "According to our data, the incidence of autism was higher in children who were vaccinated after thimerosal was eliminated from vaccines," says Dr. Fombonne.
"In the past, concern about a potential link between MMR vaccinations and autism led some parents to take the drastic step of refusing to inoculate their children against dangerous childhood diseases like measles," says Dr. Fombonne. "This action resulted in resurgence of the measles, which caused the deaths of several young children in Europe." Dr. Fombonne's study indicates that autism rates continued to increase even with reductions in the use of MMR vaccinations. "We hopes this study will finally put to rest the pervasive belief linking vaccines with developmental diseases like autism," says Dr. Fombonne.
Autism is a neuropsychiatry disorder that impairs a child's ability to communicate and interact with others. The prevalence is about 65 cases per 10,000 people (about 1 child in 155) making autism one of the most common childhood disorders. The Psychiatry Department at The Montreal Children's Hospital sees about 350 new cases of autism each year. However, Dr. Fombonne stresses that there is no demonstrated autism epidemic. He attributes the rise in autism rates to a broader definition of autism and greater awareness of the disorder.

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...
