Gold nanoparticles are these days often used in medicine for purposes of treating and diagnostics of various diseases. However, scientists from all over the world have hot arguments about possible toxicity of this product of nanotechnologies and ability of these particles to cause mutations in living beings.


Smoking is not very popular now, since medics and scientists proved how dangerous inhaling tobacco smoke is to our health. In order to explain benefits of healthy lifestyle to people, scientists decided to learn more about people, who use to smoke.


Research, performed in Russia and other countries, revealed that formation processes of psoriatic and atherosclerotic plaques could have common mechanisms.


Existing treatment for the Parkinson's disease improves motion behaviour of patients, but do not protect their neurons from deterioration and death. This means these drugs eliminate sysmptoms, but don't really cure the disease. Russian researchers currently work on a treating agent, which can prevent neuros from dying, and are testing the drug.


Researchers from Russia developed a new technique of nanolithography for carbon-based materials, involving anodic oxidation by means of a probe of an atomic force microscope.


Russian physicists now know how to insert thinnest graphite layers into diamonds in order to later make various parts for electronic and optoelectronic devices


Russian researchers have developed a new type of composite nanoparticles, which successfully deliver porphyrines (for combating cancer) to target tissues. Luminescence can enhance photodynamic effect and helps control distribution of nanoparticles in living tissues.


Natural resources will definitely end sometimes, and we seem to get buried under giant heaps of rubbish. Where mankind should put all these wastes? Many countries have found a nice solution for this burning problem and even get profit of it. Russia recently also started working in this direction.


In our everyday life we spend a good deal of time being under influence of weak electromagnetic radiation it can come from mobile phones or microwave ovens, for instance. Active debates about possible danger of this type of radiation take place all over the world. New facts on the subject arrive from Russian researchers.


Scientists and farmers actively seek the answer to the question whether changing of feeding conditions can affect edibility characteristics of chicken eggs. Russian researchers are now one step closer to finding the right answer.


Russian researchers discovered that light, which got through a light-adjusting film, has stimulated biochemical activity of oil-degrading bacteria of genus Pseudomonas: Pseudomonas stutzeri and Pseudomonas putida.


When we hear the word radiation, we are often scared, because of atomic bombs and Fukushima nuclear power plant. People should not worry small radiation doses can make bodies transparent in order to find ailing parts, as well as search for dangerous objects in luggage and heal malignant tumors.


Russian researchers from Mendeleev University of Chemical Technology know how to make activated carbon filters for purifying air from petrol vapours and light-end oil products from fruit pits and nut shells.


A Russian astrophysicist suggests that our Universe never started with the Big Bang. Data, he obtained in his observations, can destroy existing theory of how our Universe had been born.


Wastes from large industrial enterprises are often extremely harmful for the environment and human health. Waste waters of Kazan Optical Mechanics Plant, for instance, are mainly polluted by heavy metal ions from a galvanizing room and synthetic surfactants from an optical room. Heavy metal ions are much more dangerous for our health, than synthetic surfactants (SS).


Hydrocarbons still give up to 90 per cent of energy, consumed by the mankind. We try to reduce usage of oil and natural gas, at the same time trying to find alternative energy sources and to make the best use of already known sources.


Russian physicists and physiologists have developed a technique for recognition of things people imagine, by means of electroencephalography. NeuroG technology was created by researchers from faculty of physics of Moscow State University and the Institute of Higher Nervous Activity and Neurophysiology of Russian academy of sciences.


Our heart provides blood supply in our organism via two simultaneous mechanisms. Systemic circuit brings oxygenated blood to all organs and tissues, removing carbon dioxide from them at the same time. Pulmonary circuit is responsible for delivering blood from heart to lungs this mechanism enriches blood with oxygen and cleans it of carbon dioxide. A great mystery of our life is how enormous volumes of blood tend to get oxygen-enriched in lungs within very short periods of time. Little is known about blood microcirculation in lungs.


A technology, known as reflective microscopy, is especially useful for working in soft X-ray radiation range, in which laboratory X-ray lasers and free-electron lasers already work. Researchers from the laboratory of X-ray optics of the Lebedev Institute of Physics currently search for solutions for a parabolic equation with initial conditions, preset on surfaces of various forms and orientations.


Superconductors are known to have zero electric resistance under conditions of extremely low temperatures. Electron flow, responsible for formation of electric current, moves in these conducting materials without colliding with atoms of their crystal lattices, thus without any heating losses. Nowadays superconductors are used for building high-capacity magnets for expensive research equipment and for high-precision diagnostic medical devices.
