Hydrogen peroxide is usually used for cleansing scratches and cuts. However, this is not the only one possible application of this substance in medicine. The vapor of a low-concentrated peroxide solution containing oxygen radicals can be used as an inhalant for an additional treatment of many illnesses. This has been established by the research team headed by V.L. Voeikov, at Biological Faculty of Moscow State University.
It is fashionable now to blame free radicals for all deadly sins, since it has been proved that their formation in the organism is connected with different illnesses and aging. On the one hand, it is true: the radicals act as "terrorists" and can harm a sensitive biochemical system through oxidizing lipids, damaging membranes, and destroying DNA and proteins.
On the other hand, experiments on rats and mice have shown that animals put into the atmosphere containing no superoxide radicals die in one or two weeks. Later it was found that organism not only uses external sources of highly-reactive forms of oxygen, but also produces them with the aid of certain enzymes. Such forms of oxygen have been first found in the cells performing immune functions (neutrophiles and phagocytes).

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.
For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...
What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.
To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
