Ticks as small as a freckle can transmit a number of illnesses for which there is no vaccine and, in some cases, no cure. These creatures even could become bioterrorism weapons.
To find new ways to control the tiny animals and halt the spread of the pathogens they carry, Purdue University researchers and colleagues from the University of Connecticut Health Center, the University of Notre Dame and Massachusetts Institute of Technology are undertaking the job of unraveling the genetic makeup of one variety of the creature, called the deer or black-legged tick. "This will be the first time researchers have explored a tick genome in depth," said Purdue’s Catherine Hill, project co-principal investigator. "It’s crucial to learn how ticks spread serious illnesses because of the global health threats these diseases pose. "From a bioterrorism standpoint, it’s pretty clear ticks could transmit a number of diseases that intentionally could be introduced and conveyed to people."
The scientists involved in this project have formed the International Ixodes scapularis Sequencing Committee. One of the potential outcomes of this project may be development of vaccines to block transmission of microbes that cause tick-borne illnesses, said Hill, who spearheaded efforts to gain National Institutes of Health backing for the initial stages of the tick genome venture.

Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....

An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
