Consciousness during general anaesthesia is an extremely distressing condition leading to post-operative psychological trauma and contributes towards patients' fear of surgery. Dr Avidan, a member of Faculty of 1000 Medicine and a leading authority on Anaesthesia and Pain Management, writes that intra-operative awareness with subsequent recall is surprisingly common, affecting around 1 in 500 surgical cases. These appear to be mostly preventable.
There are currently a number of candidate awareness monitors available to anaesthesiologists and theatre staff, but attention has focussed on the bispectral index (BIS) monitor, which is used widely in operating rooms and intensive care units around the world. However, it is not clear that the reduction in awareness reported with BIS monitors is attributable predominantly to the technology itself. Controversially, recent research suggests that previous cases of awareness with explicit recall might have been prevented by implementing a simple 'increased vigilance' protocol. Such a protocol would cost less and be less prone to machine malfunction.
Large, prospective randomized trials are currently underway to evaluate effective awareness monitoring technologies, with the aim of ultimately improving intra-operative patient care. Avidan says, "Cost effective interventions that increase vigilance should be implemented to decrease the likelihood of this complication."

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.
