Strictly speaking, the ‘choked’, i.e., inactivated three viruses (A1, A2, B) in the new vaccine will be the same as before. They are included in the vaccine composition on the recommendation of the World Health Organisation. But the additional substances, however, proposed by the researchers, are what make it possible to make this vaccine in tablet form. What is more, believe the authors, this vaccine will be more efficient than all known equivalents. Not because an injection is replaced with a tablet, but because the authors propose to include a so-called adjuvant into the vaccine composition; put simply – an enhancer for the effect of the vaccine. The scientists are already confident of its effectiveness: A similar, intranasal vaccine which they developed previously (what specialists call nasal drops) with the same adjuvant is already at clinical trial stage. The first volunteers will be testing it in the first clinical trials this autumn.
So, the most important component of this vaccine is Korauban, an original immunostimulant, or a substance that intensifies immunity. Its correct name is a stimulant of immunogenesis, a gamma-interferon inductor. This is a close relative of regular cellulose; the same polysaccharide, only of a slightly different structure. It is produced by ‘specially trained’ microorganisms and it serves to enhance the action of the vaccine.
Korauban, if we are to greatly simplify the matter, calls special cells, which are to eliminate alien elements, to where the decontaminated virus has struck, and it presents the enemy to them. As a result the organism strenuously produces protection – special proteins (antibodies) and cells, both directed to the form of the enemy. What is of especial importance is that, as a result, humans produce so-called local cell immunity, of a long-term and wide-ranging action; not only against the used vaccine and existing epidemic viruses, but also against the pathogens of future epidemics. And in the region of the nose and throat. It is with damage to the latter, incidentally, that the illness begins. In the first days flu usually passes without a cold.

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.
