The family of bacteria that causes tuberculosis (TB) and leprosy are notoriously sturdy. And although the diseases they cause have been held in check for the past 50 years by antibiotics, some strains are becoming increasingly resistant to existing therapy.
Now, however, a new chink has been found in the cellular armor that makes these infectious diseases difficult to treat. The discovery, reported today (May 9) in the online editions of the journal Nature Structural & Molecular Biology by a team of chemists and biochemists from the University of Wisconsin-Madison, opens the door to the development of a new family of antibiotics to treat diseases that still claim as many as 3 million lives annually worldwide.
"Most of the treatments we have for these diseases date from the 1950s," says Laura L. Kiessling, a UW-Madison professor of chemistry and the leader of the team reporting the new discovery. "Many traditional antibiotics dont work against tuberculosis."

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...
