Researchers scrambling to combat a virulent form of bird flu that could mutate into a form easily spread among humans should consider developing vaccines based on DNA, according to British biochemical engineers. DNA vaccines, they say, can be produced more rapidly than conventional vaccines and could possibly save thousands of lives if a global influenza outbreak occurs.
A DNA-based vaccine could be a potent weapon against this emerging threat, particularly if enough conventional vaccine isnt available, according to Peter Dunnill, DSc., and his colleagues at University College London. However, they caution that any DNA vaccine should only be used as needed to slow the spread of the disease because the technique is largely untested in humans. The analysis appears in the November-December issue of the journal Biotechnology Progress, a co-publication of the American Chemical Society and the American Institutes of Chemical Engineers.
The avian virus, H5N1, has spread among birds throughout Southeast Asia and has been recently detected in Eastern Europe. The virus has killed more than 60 people in Asia since 2003 and forced the slaughter of millions of birds. There are no confirmed cases of human-to-human transmission of this flu, but that could change as the virus continues to mutate, Dunnill says.

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.
