According to the World Health Organization, Tuberculosis (Mycobacterium tuberculosis or TB) will kill two million people this year, with the projected number of new infections over the next twenty years reaching a billion. A rapidly moving, constantly mutating disease, TB’s effects are made worse by its ability to quickly react to new drug treatments, becoming resistant to antibiotics. Searching for a way to improve treatment, a group of researchers from the University of Tennessee developed a model to determine the most effective way of managing the bacteria’s resistance.
Drug cycling is one of many drug use policies that can be applied to treat illness and manage the resistance of viruses and bacteria. Depending on when a person becomes infected, they are placed in a group to receive a particular drug treatment. Groups infected later or earlier are treated with different drugs. Mathematical model results support that cycling is potentially useful as a tool for controlling the resistance of pathogens such as Tuberculosis.
“Tuberculosis resistance is not just an issue to minimize locally; it’s a global concern,” says Scott Duke-Sylvester, one of the researchers who will present the group’s work at the Modeling session during the Ecological Society of America’s Annual Meeting.

Researchers from the University of Hamburg in Germany, in collaboration with colleagues from the University of Aarhus in Denmark, have synthesized a new superconducting material by growing a few layers of an antiferromagnetic transition-metal chalcogenide on a bismuth-based topological insulator, both being non-superconducting materials.
While superconductivity and magnetism are generally believed to be mutually exclusive, surprisingly, in this new material, superconducting correlations...
Laser-driving of semimetals allows creating novel quasiparticle states within condensed matter systems and switching between different states on ultrafast time scales

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...
