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.

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
