A key toxin associated with whooping cough helps the germs resist the human immune system and infect vaccinated populations. Discovery of this resistance mechanism could lead to potential new treatments for the disease, according to researchers at Penn State.
Whooping cough, or pertussis, is a highly contagious respiratory disease caused by the germ Bordetella pertussis. Whooping cough can occur at any age but is generally considered a childhood disease marked by severe spells of coughing and a characteristic whooping sound while inhaling. Though the widespread use of vaccines has helped reduce disease drastically, recent surveys reveal that the disease is increasingly being diagnosed in a large number of vaccinated adults, posing a serious health risk to unvaccinated children and infants.
"One of the great mysteries of pertussis is how it persists within populations despite high vaccination rates," says Eric Harvill, assistant professor of microbiology and infectious disease in the College of Agricultural Sciences.

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...
