Electron-beam computed tomography (EBCT) is more accurate than conventional catheter angiography for detecting a dangerous congenital heart abnormality that could cause sudden death, according to research by a Saint Louis University radiologist published last month in Catheterization and Cardiovascular Interventions: Journal of the Society for Cardiovascular Angiography and Interventions.
Esat Memisoglu, M.D., assistant professor of radiology at Saint Louis University School of Medicine, and his team – which included another radiologist and several cardiologists – studied 28 adults at a heart hospital and imaging center in Istanbul, Turkey, who had undergone conventional X-ray angiography for chest pain or shortness of breath and then later underwent an EBCT.
In half of the patients, angiography showed a congenital abnormality – for example, a left coronary artery originating from the right side of the aorta, or vice versa. EBCT also detected the abnormalities, but in more than a third of the cases, it was able to provide information the angiography could not. Specifically, it could confidently determine whether the artery traveled perilously between the aorta and pulmonary artery, putting that patient at risk for a heart attack or sudden death, Memisoglu says.

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...

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...
