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).

A new assessment of NASA's record of global temperatures revealed that the agency's estimate of Earth's long-term temperature rise in recent decades is accurate to within less than a tenth of a degree Fahrenheit, providing confidence that past and future research is correctly capturing rising surface temperatures.
The most complete assessment ever of statistical uncertainty within the GISS Surface Temperature Analysis (GISTEMP) data product shows that the annual values...
Physicists at the University of Basel are able to show for the first time how a single electron looks in an artificial atom. A newly developed method enables them to show the probability of an electron being present in a space. This allows improved control of electron spins, which could serve as the smallest information unit in a future quantum computer. The experiments were published in Physical Review Letters and the related theory in Physical Review B.
The spin of an electron is a promising candidate for use as the smallest information unit (qubit) of a quantum computer. Controlling and switching this spin or...

With a quantum coprocessor in the cloud, physicists from Innsbruck, Austria, open the door to the simulation of previously unsolvable problems in chemistry, materials research or high-energy physics. The research groups led by Rainer Blatt and Peter Zoller report in the journal Nature how they simulated particle physics phenomena on 20 quantum bits and how the quantum simulator self-verified the result for the first time.
Many scientists are currently working on investigating how quantum advantage can be exploited on hardware already available today. Three years ago, physicists...
'Quantum technologies' utilise the unique phenomena of quantum superposition and entanglement to encode and process information, with potentially profound benefits to a wide range of information technologies from communications to sensing and computing.
However a major challenge in developing these technologies is that the quantum phenomena are very fragile, and only a handful of physical systems have been...
