An often-used tool to diagnose very common and sometimes limb-threatening bone infections in persons with diabetes may not be as reliable as many once believed, based on a recent study by a transatlantic team of researchers. The study, published to the Web ahead of print in February's edition of the journal Diabetes Care, longitudinally evaluated a large sample of persons with diabetes with wounds, and tested the commonly performed "probe to bone" test. The test, which uses a sterile instrument to feel for bone inside a wound, has been thought by many to be highly predictive of bone infection.
"It certainly makes sense that if you can feel bone, then it must be infected," noted David G. Armstrong, DPM, PhD, Professor of Surgery at Scholl's Center for Lower Extremity Ambulatory Research (CLEAR) at Rosalind Franklin University of Medicine and Science, and a co-investigator on the study. "Unfortunately, though, this doesn't always seem to be the case. The test, if used by itself in a normal clinical setting, isn't much better than flipping a coin. We therefore recommend it be used with other aids, such as biopsy or appropriate imaging tools."

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.
The results will be published on March 22 in the journal „Astronomy & Astrophysics“.
Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...
Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.
Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
