An international group of astronomers has detected an interesting radio signal spike, one that could possibly be of alien origin, from a star system located 95 light-years away.Few details have been released so far, but more information about the finding will be announced at the International Astronautical Congress IAC , which will be held in Guadalajara, Mexico during the last week of September.Of course, it is very likely that the radio spike was produced by something else entirely, like Earth-based radio interference or even a technical glitch in the observing equipment.However, these follow-up observations from other organizations have not yet been possible because those who detected the signal sat on the discovery for over a year for unknown reasons.It s believed that if ET were to attempt contact, it would likely be through powerful radio waves, which travel through the universe at the speed of light.If we wanted to send a message to a civilization far away, this is what we d do, so for now, we assume that intelligent aliens would do the same.
Ars was among the first news outlets to report on discussions among astronomers about observations of an intriguing "signal" that may have originated from a distant, Sun-like star.We cautioned readers that, because the signal was measured at 11Ghz, there was a "significant chance" it was of terrestrial origin, likely due to some military activity.First, astronomers with the search for extraterrestrial intelligence downplayed the possibility of an alien civilization."There are many other plausible explanations for this claimed transmission, including terrestrial interference," Seth Shostak, a senior astronomer with SETI, wrote.Now the Special Astrophysical Observatory of the Russian Academy of Sciences has concurred, releasing a statement on the detection of a radio signal at the RATAN-600 radio astronomy observatory in southern Russia."Subsequent processing and analysis of the signal revealed its most probable terrestrial origin," the Russian scientists said.
Stand down, one and all: there's not even cool new science in this week's alien signal , let alone a SETI success: the signal seems to have come from a Russian military satellite.The odd signal turned up over the weekend: an 11 GHz picked up by Russia's RATAN-600 telescope.The original observation, it was thought, might have originated from a star system called HD164595; if it had, it would have represented a stupendous energy output.Organisations like the SETI Institute were cautious from the start, calling the signal interesting and saying the signal would have to be followed up with other telescopes.Those other telescopes can go back to their scheduled programming, because RATAN-600's operators, the Special Astrophysical Observatory of the Russian Academy of Sciences, has issued this statement.Subsequent processing and analysis of the signal revealed its most probable terrestrial origin , the observatory remarks.
A massive stone structure, dating back 1,500 years, has been discovered along the Caspian Sea.A massive, 1,500-year-old stone complex that may have been built by nomad tribes has been discovered near the eastern shore of the Caspian Sea in Kazakhstan.The complex contains numerous stone structures sprawled over about 300 acres 120 hectares of land, or more than 200 American football fields, archaeologists reported recently in the journal Ancient Civilizations from Scythia to Siberia."When the area was examined in detail, several types of stone structures were identified," archaeologists Andrey Astafiev, of the Mangistaus State Historical and Cultural Reserve; and Evgeniï Bogdanov, of the Russian Academy of Sciences Siberian Department's Institute of Archaeology and Ethnography, wrote in the journal article.See Photos of the Massive Stone Structure and Artifacts The structures are "made of stone slabs inserted vertically into the ground," the archaeologists wrote.
Samsung has already been testing with the programming method since late 2015 and plans to use it in its future devicesSamsung has invested close to $10m £7.85m in a Russia-based software solution that aims to make apps on its devices more stable by fixing errors in source code of Tizen apps, native Samsung apps as well as some Android apps.The programming solution has been developed by the Institute for system programming of the Russian Academy of Sciences ISP RAS called Svace.The investment does not make Samsung the owner of the solution or give it exclusive rights to the product but the company can use it for free.A standard programmer can make up to 20 mistakes on a average while writing 100 lines of codes.Svace can dramatically reduce the number of errors in these codes written in C, C , C and Java and also detect potential vulnerabilities that can be exploited by hackers.
Scientists from the Moscow Institute of Physics and Technology (MIPT) and the Kotelnikov Institute of Radio Engineering and Electronics (IRE) of the Russian Academy of Sciences (RAS), in collaboration with their colleagues from Finland, have developed a new type of optical fiber that has an extremely large core diameter and preserves the coherent properties of light.The results of the study are promising for constructing high-power pulsed fiber lasers and amplifiers, as well as polarization-sensitive sensors.There are two principal parameters that often need to be preserved: the distribution of light intensity in cross section and the polarization of light (a property that specifies the oscillation directions of the electric or magnetic field in a plane perpendicular to the wave propagation direction).In their study, the researchers managed to fulfill both conditions.It varies along two orthogonal axes, and its diameters change proportionally along the fiber.An optical fiber is generally a very thin flexible strand drawn from glass or transparent plastic.
MIPT researchers teamed up with their colleagues from the Kotelnikov Institute of Radio Engineering and Electronics (IRE) of the Russian Academy of Sciences (RAS) and the International Associated Laboratory of the Critical and Supercritical Phenomena in Functional Electronics, Acoustics, and Fluidics for a successful demonstration of a new kind of computer memory.Their paper was published in Applied Physics Letters.A transition to the newly demonstrated type of memory could enable a substantial energy saving, as well as the instantaneous startup of devices based on this technology.Random access memory, or RAM, is one of the principal components of any computer or smartphone.The most common type of RAM is known as dynamic random access memory, or DRAM for short.It is a semiconductor memory based on a rather simple principle.
Scientists have determined the properties of unseen "tails" sticking out of supermassive black holes at the heart of active galactic nuclei by analyzing unexpected discrepancies between the data of high-precision observations conducted by an international network of radio telescopes and that of Gaia -- a space observatory of the European Space Agency carrying optical telescopes on board."It is no exaggeration to say that a new area of observational astrophysics has begun," says Yuri Kovalev who heads MIPT's Laboratory of Relativistic Astrophysics and a laboratory at the Lebedev Physical Institute (LPI) of the Russian Academy of Sciences."By comparing the data from radio interferometers and optical telescopes, we can obtain information about hot jets and the accretion disks surrounding black holes at the center of galaxies in the visible part of the spectrum.Yuri Kovalev and Leonid Petrov from MIPT and LPI collaborated on a research paper, which has recently been published in Monthly Notices of the Royal Astronomical Society, that analyzes the coordinates of active nuclei of remote galaxies obtained independently by very long baseline interferometry, or VLBI, and the Gaia space astrometry observatory.In 2013, the European space observatory Gaia was launched with an aim of cataloging the precise coordinates and velocities of 1 billion stars in our Galaxy.More than 10,000 of these are extremely bright active galactic nuclei called quasars.
A team of researchers from the Moscow Institute of Physics and Technology (MIPT) and the Institute for Theoretical and Applied Electrodynamics (ITAE) of the Russian Academy of Sciences (RAS), in collaboration with a colleague from RIKEN (Institute for Physical and Chemical Research in Japan), has provided theoretical proof of the existence of a new class of materials.The discovery will find use in implantable electronics, alongside devices based on graphene, nanotubes, and a number of other promising materials.This might give rise to a new direction in search for "nonmetallic" half-metals, i.e., those that do not contain atoms of transition metals, such as nickel, manganese, and lanthanum.Around the turn of the century, the use of giant magnetoresistance materials in magnetic field sensors (used to read data in hard disk drives) has enabled the storage of much larger amounts of data on HDDs.They were first predicted based on computer simulations and later proved to exist experimentally.As for spin-down electrons, their energy is too high, and therefore they cannot carry charge current.
Researchers from MIPT teamed up with their colleagues from the Keldysh Institute of Applied Mathematics of the Russian Academy of Sciences (KIAM RAS) and Lomonosov Moscow State University to develop a mathematical model of information warfare in a society under periodic destabilization.In addition to providing an analytical solution of the problem, the researchers have conducted a numerical experiment that illustrates their model.They determine if the study is going to be a success and put a limit on the potential accuracy of the results," explains Alexander Petrov, a leading researcher at KIAM RAS, who co-authored the paper.Some of them, for example, are based on a neurological scheme proposed by Nicolas Rashevsky, a Russian-born U.S. physicist and pioneer of mathematical biology and psychology," says Petrov.Mathematicians tackle this vast and seemingly subjective problem by formulating differential and integro-differential equations.The numeric values of these coefficients to be fed into the equations were obtained by integrating data and thus do not represent individual human features.
"A comprehensive program for research on Venus and for creating an interplanetary station there is being developed.""A comprehensive program for research on Venus and for creating an interplanetary station there is being developed.Russia's federal agency for scientific organisations (Fano) and the Space Research Institute of the Russian Academy of Sciences, are working on presenting a comprehensive programme to launch a space probe to Venus.They are also planning to have an interplanetary station in its vicinity.The first concept conference with participants in the Venera-D (Venus Long-Lived) has been held.Fano has said that the programme is still at an initial phase.
A team of scientists from Krasnoyarsk Scientific Center (Siberian Department of Russian Academy of Sciences) and Siberian Federal University synthesized thin crystal ferromagnetic films and developed a technology for their shaping.The results of the study were published in Thin Solid Films journal.Iron silicides are compounds of iron and silicon that usually have ferromagnetic properties when subject to certain temperatures.Films like this are used as active parts in optic and photonic devices, as well as in integral electronic and spintronic chips.Devices like this consume less electrical energy and have higher operating speed compared to traditional electronic ones.However, to develop such devices scientists need films to be specifically shaped.
Russian scientists from Ural Federal University (UrFU) together with their colleagues from Institute of Metal Physics of the Ural Department of Russian Academy of Sciences studied fundamental characteristics of nickel oxide nanocrystals and found excitons on the light absorption edge for the first time.An exciton is an electron-hole pair bound with electrostatic coupling that migrates in a crystal and transmits energy within it.The presence of an exciton in the studied area allows for detailed research of edge parameters in permitted energy bands.The results of the study were published in Physica B: Physics of Condensed Matter journal.It is impossible to imagine modern world without electricity.A group between them is called semiconductors.
A team of researchers at the Institute of Synthetic Polymer Materials of the Russian Academy of Sciences, MIPT, and elsewhere has found out how the regularity of polypropylene molecules and thermal treatment affect the mechanical properties of the end product.A polymer molecule is a long chain of repeating units of unequal length.If these molecules are jumbled up more or less at random in a material, it is said to be amorphous.This gives rise to regions of highly regular atomic structure (fig.1), similar to that of crystals, hence their name: crystallites.King of plastics calls for macromolecular order
A joint team of scientists from Russia and the United States designed a method for marking dividing stem cells with three different labels.The new method will increase the accuracy and speed of stem cell division analysis and reveal new populations of stem cells.The research team, led by Grigori Enikolopov, was made up of specialists from the Moscow Institute of Physics and Technology (MIPT), Stony Brook University (USA), Cold Spring Harbor Laboratory (USA), and Koltzov Institute of Developmental Biology of the Russian Academy of Sciences.Usually, tissue regeneration proceeds in the following manner: After stem cells duplicate themselves, some of their offspring are used to restock the supply of stem cells, and some convert into other types of cells in order to repair the loss or damage.What the scientists aim to discover are the mechanisms common to all types of stem cells and the ways they can be influenced or improved.As a stem cell duplicates itself, it goes through a stage called the S phase (see fig.
An analytical article based on the study of morphologic and chemical composition of particulate matter in motorcycle engine exhaust was published in the respected scientific journal Toxicology Reports.The group of authors was supervised by Aristidis Tsatsakis, a foreign member of the Russian Academy of Sciences and Doctor Honoris Causa of the Far Eastern Federal University, and Kirill Golokhvast, doctor of biology and Provost for Research at FEFU.The study was supported with a grant of the Russian Science Foundation.Taking into account the growth of manufacture and sales of motorcycles all over the world, especially in Asia and Africa, residual products that do not disintegrate in the course of internal combustion become a major factor impacting the environment.Even the engines with an afterburning system become the source of emission of numerous particulates with high contents of polyaromatic hydrocarbons (PAH) less than 10 micrometers in diameter (see Table 2).Particulate matter of such size, depending on chemical composition, is considered the most dangerous both for people's health and the environment which is confirmed by studies.
To achieve breakthrough research results in various fields of modern science, it is vital to develop successful interdisciplinary collaborations.Long-term interaction of physicists from the Institute of Applied Physics of the Russian Academy of Sciences, researchers from Chalmers University of Technology and computer scientists from Lobachevsky University has resulted in a new software tool PICADOR developed for numerical modeling of laser plasmas on modern supercomputers.In their article published in Scientific Reports, Nizhny Novgorod scientists have formulated the conditions (that were found theoretically and verified in a numerical experiment), under which the avalanche-like generation of electrons and positrons in the focus of a high-power laser pulse yields the electron-positron plasma of record density.A well-known fact in quantum physics is the possibility of transformation of certain particles into other particles.In particular, in a sufficiently strong electric or magnetic field, a gamma photon can decay into two particles, an electron and a positron.Until now, this effect was observed in laboratory conditions mainly when gamma radiation was transmitted through crystals in which sufficiently strong fields exist near atomic nuclei.
A group of scientists from MSU, Frumkin Institute of Physical Chemistry and Electrochemistry of the Russian Academy of Sciences, and Juelich Research Center described the mechanism of appearance of an inertial lift force acting on finite-sized particles in microchannels.Such calculations were previously possible only for some specific cases.A more accurate description allows one to use this inertial lift for particle sorting.Precise calculations of particle migrations in microchannels will help to use them for sorting, e.g.Previous studies addressed only some simple specific cases, such as the migration of point-like particles, whose size is ignored, or finite-size particles translating in the vicinity of a single wall."Inertial microfluidics is widely known and used, but so far only at high Reynolds numbers which is difficult to generate in microchannels since it requires a huge pressure drop to pump the liquid.
A team from Siberian Federal University and Kirensky Institute of Physics (Siberian Department of the Russian Academy of Sciences) applied a new method to study nanoparticles made of cadmium telluride (CdTe).They used a peculiar feature of this compound: its interaction with light differs depending on the magnetic field.The results of the study were published in the Physics Letters A journal.The interaction of certain substances with electromagnetic radiation depends on the magnetic characteristics of the environment.When this phenomenon is present, the absorption of light with different circular polarizations differs if it moves along the direction of magnetization.Magnetization may be determined by the properties of the substance itself (in case of ferromagnetic materials) or by the influence of an external magnetic field.
