The cause of the attack was ascertained through blood tests of the victims, but that was only possible once they were already infected. Today we are all more aware of the dangers of biological weapons, but if we were to be subject to such an attack how would we quickly know whether it was a hoax or a biological threat. To tackle this problem scientists at the University of Surrey in a study sponsored by Smiths Detection have found a technique that may allow the authorities to identify biological agents more quickly and efficiently.
The problem in detecting harmful bacteria in the air is that it is mixed up with other non-biological pollutants such as diesel fumes. Until now it has been impossible to separate these non-biological particles from the bacteria which need to be tested, thus quick, accurate identification of bacteria is difficult. Dr Fatima Labeed and her team at the University of Surrey have used a unique form of the process called dielectrophoretic separation to correctly separate diesel particulates from those of an anthrax bacteria substitute. This process would enable the authorities to isolate the bacteria more quickly and therefore use the appropriate biosensing instruments to work out what form of bacteria had been released.
Whilst the process at this point has only been used to separate diesel particle from anthrax-like microorganisms, it is hoped that applications for other potentially dangerous biological materials may also be found. Dr Labeed comments. “Perhaps one day this technology could be as common as x-ray machines used in airports”

The Institute of Semiconductor Technology and the Institute of Physical and Theoretical Chemistry, both members of the Laboratory for Emerging Nanometrology (LENA), at Technische Universität Braunschweig are partners in a new European research project entitled ChipScope, which aims to develop a completely new and extremely small optical microscope capable of observing the interior of living cells in real time. A consortium of 7 partners from 5 countries will tackle this issue with very ambitious objectives during a four-year research program.
To demonstrate the usefulness of this new scientific tool, at the end of the project the developed chip-sized microscope will be used to observe in real-time...
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.
