The discovery was made after a resident brought insects to the attention of a pest control operator who identified them as kissing bugs. After researching the bug on the Internet, the resident realized the potential for Chagas transmission. Because Dr. Dorn is known in this area as the expert on Chagas disease and her ongoing international research in this field, she was contacted to administer the test for the Chagas parasite and further investigate this situation.
Both residents were tested at Loyola and the Centers for Disease Control and one resident tested positive for the exposure to the Chagas parasite. Many insects have been collected in the house and the nearby building and studies carried out by Dr. Dorn and her students over the last several months indicate that more than half of the insects tested carry the Chagas parasite.
What does this mean and what are the implications for the general public.
Although we have known for many years that there is an endemic cycle in wild animals in Louisiana (approximately 30 – 40 percent of armadillos and opossums are infected with the Chagas parasite), this is the first report of infection in a human with the Chagas parasite by an insect in Louisiana. This is not a widespread public health concern since the person was living in a rural area in a very open house with numerous entry points for insects and no air conditioning and most people in Louisiana live in much less open homes.
Dr. Dorn has spent 14 years studying Chagas disease, mostly in Guatemala. She is continuing her work on the insects that carry the Chagas parasite in Central America and Mexico and working with researchers at the LSU Veterinary School on Chagas in dogs in Louisiana.
Dr. Dorn’s scholarly paper on this significant finding will soon be published in the journal of Emerging Infectious Diseases which is published by the Centers for Disease Control. She also presented her findings at the annual meeting of American Association of Tropical Medicine and Hygiene in Atlanta in November 2006.

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...
