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.


A group of scientists from CERN, including Russian physicists, has developed an effective technique for synthesizing and trapping antimatter particles for a relatively long time. Antimatter particles were atoms of antihydrogen, consisting of antiprotons and positrons instead of protons and electrons, an article in Nature reveals.


Russian researchers advanced significantly in understanding the nature of atherosclerosis by studying how blood vessel disruption depended on various metal content in vessel walls. Experiments of chemical composition of atherosclerotic plaques revealed that zinc, previously considered to have great protective effect, was much less important than manganese.


Physicists, operating Large Hadron Collider's CMS detecting facility, recently registered production of two Z-bosons, which can be an evidence of a "heavy" variety of Higgs boson. CMS is a Compact Muon Solenoid facility, a general-purpose detector, designed for studying different aspects of proton collisions at 14 teraelectronvolt, the center-of-mass energy of the LHC particle accelerator.


Vladimir Skulachev, famous Russian biotechnologist, who studies effects of mitochondrial antioxidants on various health problems, including aging, believes that treating agents for eyes disorders, based upon Skulachev ions, as mitochondrial antioxidants are also called, can appear in pharmacies by the end of 2011.As for aging cure-all, these drugs will be available for sale within nearest 5 years.


Among other important tasks of quantum photonics there is a problem of building an interface between atoms and light photons. Joint think-tank of physicists from Russia and United States studies how single photons interact with quantum objects and has already built a prototype device for transferring information from an atom to a photon. The device is an integrated chip in an artificial atom with a fibre port. The simplest application of future device is a memory cell, as for more complicated things, this device can become a single-photon transistor, working on the level of individual quanta, for building complex logic systems.


Researchers pay more and more attention to processes of memory storage and recall. Scientists already know several proteins, which play a key role in memorization processes, and many experimental works were aimed at finding properties of these proteins. A new study of Russian physiologists is dedicated to memory loss, induced in snails and rats by means of blocking a NMDA-receptor.
