A recent paper in the New England Journal of Medicine by Moore and Copel indicated that miniaturization and a drop in costs have facilitated the growth of non-cardiac POC ultrasound by clinicians and that the concept of an "ultrasound stethoscope" is rapidly moving from the theoretical to a reality.
"The commentary by Moore and Copel raises the question of how widespread the use of non-cardiac ultrasound has become among non-radiologist physicians and how quickly such use is growing with the advent of hand-carried ultrasound devices. We used a nationwide database to investigate these questions," said David C. Levin, MD, lead author of the study.
To determine the rate of utilization of non-cardiac ultrasound by radiologists and other specialists, researchers at Thomas Jefferson University looked at Medicare Part B databases for 2004 to 2009. Between 2004 and 2009, there was a 21 percent increase in the overall utilization rate of non-cardiac ultrasound. POC ultrasound by non-radiologists amounted to 41 percent of all studies done in 2009, while radiologists performed 55 percent. Multiple non-radiologic specialties are involved, but radiologists' involvement is far higher than any other single specialty.
"The role of radiologists in non-cardiac ultrasound remains quite strong; however progressive miniaturization of ultrasound equipment may change that. As a result, utilization trends will require further watching and additional research in the coming years," said Levin.

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....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.

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...
