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.

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.

A team of scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg investigated optically-induced superconductivity in the alkali-doped fulleride K3C60under high external pressures. This study allowed, on one hand, to uniquely assess the nature of the transient state as a superconducting phase. In addition, it unveiled the possibility to induce superconductivity in K3C60 at temperatures far above the -170 degrees Celsius hypothesized previously, and rather all the way to room temperature. The paper by Cantaluppi et al has been published in Nature Physics.
Unlike ordinary metals, superconductors have the unique capability of transporting electrical currents without any loss. Nowadays, their technological...
