Good news, everyone who lives in the regions with cold climate Russian researchers have developed special additives, which help improve quality of local materials and make them suitable for making frost-proof bricks.


Many repair works in our organisms are performed by hard workers, known as stromal progenitor cells, which participate in forming new tissues and extracellular matrix. When we get old, we lose the majority of these cells, which causes bone thinning in elder people, for instance. Russian medics and microbiologists have found out that age-related changes in the population of stromal progenitor cells was not caused only by decreasing numbers of these cells, but also by inhibiting their activity by an organism himself.


Oil under the ground is often contained in so-called collectors layers of porous rocks. In order to reach black oil engineers drill wells, to which oil travels from surrounding rocks through highly porous and permeable rocks and later gets extracted. During drilling of wells or after a long-term well operation pores of oil-bearing rocks get clogged and large amount of oil is left inside the Earth forever. Such clogging is also known as wall cake or filter cake.


Erythropoietin-based treating agents are often used for therapy of anemia, caused by various severe diseases. However, these treating agents have strong side effects. Russian medics know how to treat erythropoietin in order to maintain its efficiency, but eliminate unwanted side effects.


Russian researchers have synthesized a 22-component RNA (ribonucleic acid), which demonstrated hampering of cancer cells growth and promoting synthesis of interferon, part of an immune system.


Search for promising treating agents has come a long way from testing all possible substances, hoping, that something would help, to making treatment with given properties in near future. Currently we are between these two stages with choosing from several hundreds substances and then modifying best of them by chemical means.


Russian researchers have developed a simple technique for raw material preparation in order to produce electrically conducting polymers. These polymers are an essential part of flexible displays, another technological breakthrough.


Russian researchers have suggested a new technique for accelerating healing of damaged and broken bones. The magic substance, used for this purpose, is called fibrin.


Nanostructured silicon surfaces and silicon nanoparticles were shown to inhibit division of stem cells and cancer cells, and nanoparticles, enforced with ultrasonic sound, kill these cells, Russian physicists and medics say.


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.
