A painless, portable device that uses electrical current rather than X-ray to examine breasts for cancer is under study at the Medical College of Georgia.
MCG is one of some 20 centers across the world studying impedance scanning, a technique based on evidence that electrical current passes through cancerous tissue more easily than normal tissue. Preliminary studies have shown the technique, which takes about 10 minutes and doesn’t require often-uncomfortable breast compression, can pick up very small tumors, according to its developers, Z-Tech, Inc., which has offices in South Carolina and Ontario.
The study of some 4,500 women – about 500 at MCG Medical Center – will determine whether the device, which produces a report rather than a breast image, is accurate enough for widespread use, says Dr. James H. Craft, MCG radiologist and a principal investigator. Impedance scanning involves placing a flower-shaped grouping of electrodes with a hole in the center for the nipple over each breast. A small amount of electricity is sent through the breasts and a computer immediately calculates and presents findings based on Z-Tech’s benchmarks for negative and positive results. Rather than waiting for a radiologist to look at an X-ray, the computer immediately notes whether the image is HEDA negative, meaning no cancer detected, or positive.

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.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
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...
