Russian researchers study scorpion toxins, able to selectively bind with sodium channels. These studies will help acquire new information about how ion channels toxin targets work.


Parkinson disease is a cross, born by about 3.7 million people about 7% of those, older than 60 years. Common therapy for this disease is called levodopa (L-DOPA or L-3,4-dihydroxyphenylalanine), which is known to increase dopamine concentrations. However, levodopa has lots of side effects and cannot be used as a drug for long periods of time. That is why a search for new therapy for the Parkinson disease is a burning issue for the mankind.


Researchers from Russia and China have discovered that adding small amounts of zirconium in tin oxide films changed electrophysical and gas-sensing properties of these films. For instance, tin oxide films become much more sensitive to vapours of ethanol and acetone at temperatures 100 degrees less, than without zirconium.


A new neutrino detector is built within an international Chooz-2 project by Russian and French researchers. New detector will help observe antineutrino from nuclear reactors of the Chooz nuclear power plant, Ardennes, France. Studying fundamental properties of neutrino is important for particle physics, astrophysics and cosmology.


A common means of fighting mosquitoes nowadays is using toxic bacterial proteins. However, these biological substances do not live long after being introduced in the environment; moreover, mosquitoes tend to become resistant to them quite quickly. Russian geneticists and medics united their efforts in solving this problem and suggested encapsulating toxic proteins of Brevibacillus laterosporus in protozoa before treating mosquitoes.


Russian anthropologists and biotechnologists have studied peculiar features of Neanderthal skeletons, which differed from skeletons of modern human beings, and reconstructed walk patterns and hunting strategies of ancient humans.


Solar energy is a very important part of modern alternative power engineering. New battery types tend to appear regularly and quickly become popular. Researchers work on making solar batteries more efficient making their efficiency coefficient increase from existing 20 per cent up to 30 per cent. Russian scientists used a different approach their batteries, made of multicrystalline silicon, have common efficiency coefficient, but they are much more cheap than analogues.


Russian physicists developed a new technique for making nanopowders with particles of a certain diameter a property, which lack all other technologies of nanopowder production. High-energy electron flow knocks nickel atoms out of a sample, these atoms then deposit on a substrate that is the way nanoparticles form.


Gas detonation is known to be a good means to get significant amount of energy during a very short period of time. However, detonation combustion is extremely difficult to control, and this fact limits perspectives of this technique as an industrial technology. A group of Russian scientists has a solution for this problem researchers suggest treating gaseous mixtures, in which detonation combustion takes place, with acoustic fields.


An experiment on delivering bacteria from the Earth to Mars and back aboard Russian Phobos-Grunt interplanetary station may cause irreversible changes in Marian ecosystem, an Italian researcher worries. However, Russian scientists assure Barry DiGregorio, a member of ICAMSR (International Committee Against Mars Sample Return), that bacteria from Earth would never get to Mars or Phobos.


Last week Russian engineers have opened a plant of high-accuracy machines, working by means of electrochemical machining with vibrations, in the Russian city of Ufa.


Physicists, Russian scientists among them, who work on Large Hadron Colliders CMS (Compact Muon Solenoid) detector, claim that their search for tiny black holes, which, according to some existing theories, could have appeared in proton collisions in this accelerator, was ineffective no traces of such black holes have been detected.


Russian physicists suggest a technique for quick and accurate comparison of any medication with is chemical etalon.


Russian physicists suggest using a heterodyne infra-red range spectrometer for measuring speed and direction of winds on other planets.


Russian scientists have developed a new technique for disposing of radioactive wastes, which turns them into chemical compounds similar to natural minerals and friendly for an environment.


For 1 month Russian physicists and astronomers publish information about space weather on the website of the Russian Space Agency. Among other data the website contains information about solar flares, speed of solar wind, and Earths magnetosphere, as well as magnetic storm forecast for next 27 days.


Russian physicists have developed a unique device a photoelectrochemical supercapacitor condenser, able to directly convert sunlight energy into electricity and accumulate it with high density in double electrical layer of electrodes, made of various nanomaterials. New device can be an element of autonomous solar electric generating stations, or illumination systems, being a cheap alternative to foreign solutions.


Russian researchers from Novosibirsk have found out how to make some pharmaceutical agents less toxic without losing in efficiency and healing properties. The process, which does all abovementioned things, is called clathration formation of a complex of a drug with natural polysaccharides.


Russian researchers revealed that Rhodobacter sphaeroides bacteria can be a source of molecular hydrogen, an ecologically friendly fuel. Scientists studied various strains of the mentioned microorganism and demonstrated that hydrogen emission rate depended on pigmentation of cells. Less pigmented strains can be a promising source of molecular hydrogen.


Hepatic (liver) fibrosis is a devastating disease, which requires a not very pleasant procedure of biopsy to be detected. However, Russian medics developed a technique, which allows skipping this painful diagnostic method and estimating the level of liver fibrosis on the basis of biochemical measurements.
