The media reported about the threat of disruption of the timing of the first launch from the Baikonur East – RBC

The tests at the technical complex Vostochny cosmodrome is under threat, which will certainly affect the timing of the first rocket launch, the newspaper “Kommersant” with reference to the letter of the general director of the state corporation “Roscosmos” Igor Komarov led Spetsstroy Alexander Volosovo.

In letter Komarov reports led Spetsstroy that, according to the instructions of President Vladimir Putin, all construction and installation work on the launch sites and their transfer to the operation were to take place before 10 February. However, the obligation to connect objects and interior systems engineering support to not fully implemented. At the launch complex work performed at 89%, and water intake facilities – 48%, and security systems – 40%

According to the letter, not a single building starting wage in the operation do not put, and deadlines for submission of executive documentation. obtain an opinion on the construction of nine objects trigger the minimum is not met. Of the 67 points dogonochnogo plan was eight, the backlog of approved duration is from 2 to 47 days. Head of “Roscosmos” warns that this situation jeopardizes the beginning and complex tests on complex technical systems. “The transfer of the test will cause the failure of terms of preparation and launch rockets” Soyuz-2 “, – says Komarov

The decree on the establishment of the Eastern Putin signed November 6, 2007.. The first launch from the Baikonur planned for December 25, but President in October 2015 transferred it. He asked, “adjusted in the spring,” and added that it would be good to have time to run to start the Cosmonautics Day on 12 April. Later, CEO of Samara Rocket and Space Centre (RCC) “Progress” Alexander Kirilin, said that the launch is scheduled for April 25. In the Roskosmos date not confirmed. The representative of the corporation said that it “will be determined only after the end of autonomous and complex tests.”

Scientists have created a “living, breathing” bio-computer – Globalural.com

 

A few years American scientists, together with colleagues from the Netherlands, Sweden and Germany were working on a project to create a prototype “living and breathing” bio-computer. The researchers describe a mathematical computer model, which works on the principle of a living organism. A prototype has already been successfully established itself

The main advantage of bio-computer – it is his size:. 1.5-inch processor is much smaller than the one to which we are accustomed. The computer is not heated, since its inception used proteins. We also know that news consumption is minimized. Biocompost working on a special compound – adenosine triphosphate, which provides energy to the cells of living beings. The mechanism of energy supply, scientists compared with breathing mechanism

Project developers believe that bionovinka -. This is the first step towards a lifetime of “breathing machines”, which are based on the work of living cells

Experts from the United States and the Netherlands as well as Germany and Sweden for two years worked on the special project for the development of models of biological computer. The results of their project, scientists have provided the scientific magazine Science News.

Researchers have shown spetsmodel mathematical apparatus, based on the work on the principle of a living organism, it transmits rsute.ru. Scientists have invented a unique model, which is already popular

The main thing in this biocomputer -. It is its size. The processor is just 1.5 centimeters, which is many times smaller than a modern PC. A unique computer during operation is not heated due to the fact that it consists of protein.

In addition, power consumption is very minimal. The new PC is running on spetssoedinenii – adenosine triphosphate. Just this compound helps to satiate the energy cells of living organisms.

The processor’s unique PC looks like a scheme of movement on city streets. Because the channels of the microchip, as the cars moving molecules provides the energy of adenosine triphosphate. This mechanism of energy supply experts equate to the mechanism of breathing

Scientists believe that this development -. It is an important step towards the industry living machines. In the course of their activities involving living cells. The main thing – a reduction in the incoming energy in the process of high productivity

Scientists note that started on the basis of their biocomputers development will be more efficient and less energy-intensive.. Live computers perform operations not consistent, and in parallel, that is several times faster than electric ancestors. In addition, bioelements consume one operation a hundred times less energy.

How to identify the cause headache pain in the scene of 3D-films – BBC

Many of us at least once in your life go to the cinema to watch 3D-film, and it is likely experiencing some discomfort while – headache, eye pain, heaviness in the forehead area. According to statistics, these problems are not uncommon. In 2011, the French researchers conducted a survey, trying to understand how people feel after watching of 3D-films. It was found that

Only one-third of the audience watching these movies, without experiencing any problems, 27% feel “discomfort”, 22% complain about the deterioration of health, 7% experienced severe headaches pain,

Live microchip created by scientists – REGNUM

Washington, February 29, 2016, 16:05 – REGNUM Biological supercomputer created by a group of scientists from the USA, Holland, Sweden and Germany, reports Science News.

In 2015, experts from Columbia University announced the creation of a microchip on the basis of adenosine triphosphate molecules. These molecules are considered to be a universal source of energy for all biochemical processes. This energy is transformed into electrical energy and feeds the chips.

Now, scientists claim to have created a workable prototype as small as 1.5 centimeters. It requires very meager amount of power as opposed to the currently existing analogs.

Scientists note that biocomputers created on the basis of their development will be more efficient and less energy-intensive. Live computers perform operations not consistent, and in parallel, that is several times faster than electric ancestors. In addition, bioelements consume one operation a hundred times less energy.

Create a full bio-computers is still difficult, but it is real, scientists say.

20 most expensive companies Runet: rating Forbes – Forbes Russia

In December 2015 Naspers Fund completed the acquisition of 50.5% stake Avito. The company, established in Russia by two Swedish entrepreneurs, taking into account the debt was estimated at $ 2.7 billion. Does this mean that all boards can now count on the same multiples in assessing? Not at all.

The fund iTech Capital noted that the prospect of the industry is no longer a decisive factor for investment decisions. The focus shifted to the effectiveness of a particular company, its performance, achievement, business model, team – anything that allows more thorough approach to risk assessment.

As we consider

^{data revenue (excluding VAT) are provided by the companies themselves. In other cases, it provides an assessment obtained by interviewing market participants and analysts. We took the company has initially counted on the business on the Internet, created in Russia or mainly operating in the Russian market. In this project, there are no companies from fast-growing sphere finteha business model which strongly distinguishes them from other participants. The capitalization of public companies is given according to the stock exchange on February 1, 2016. All other figures on the cost – expert assessment of Forbes. For each company, they are calculated based on multiples of peers, trades, scores of venture capitalists. Thank you for consulting experts iTech Capital, UFG, InVenture Partners, Genesis Technology Capital, Maxfield Capital, Prostor Capital, Almaz Capital and Venture Angels.}

«Money is not to those who simply create something interesting and promising, and those who fundamentally changes the industry”, – analyzes notable transactions, Alexei Solovyov, Managing Director of Prostor Capital. Avito bypassed absolute monopoly in personal ads – the company “Hand in Hand” – just due to the new business model. Baring Vostok Fund this year invested in a service for buying used cars CarPrice (in the same round of Almaz Capital has increased its stake) and mapping service 2GIS (with fund ru-Net Leonid Boguslavsky). Both companies offer the market new models

Maxim Shekhovtsov, managing partner of Genesis Technology Capital, believes that the situation with the ruble exchange rate can be perceived with optimism. “As never profitable to invest in companies with product development in Russia” . However, an important factor for investors becomes the presence of revenue in hard currency. The same 2GIS, for example, operates in Cyprus, Padua, Venice, Prague, Santiago and Dubai.

If you look at the biggest rounds of venture capital financing, not only in Russia, you can see the obvious trend of displacement of interest from a business online only to services that help to link offline with online, so-called online-to-offline, – this is Uber, and Gett, and Airbnb, and Food Panda, and Instacart. “If earlier such models were limited to just a message board, the trend in recent years – is to get transactional commissions, which allows to move from classic online advertising revenue to divide more offline pie. After all, as the main markets are offline, so for a long time there and will remain, “- says Eugene Timko, investment director InVenture Partners.

Alex Tuknov, chief investment Maxfield Capital, notes that at the forefront of business model, focused on flexible and less costly ways of providing services, the reduction of inefficient idle resources. “New solutions come in stagnant in terms of digital innovation industry”, – he predicts.

So that investment in Internet companies will be accurate. And “Exit” from the business, too. Not least because the market is consolidating and larger players will buy smaller ones. Unless, of course, they work effectively.

In our rating should have been at least two other companies. Why are they not? Telegram Messenger, who in Russia began to create Pavel Durov’s team evaluated does not make sense – the founder of Mashable in an interview said that the foreign investors in the messenger and never will be. A holding company Rambler & amp; Co did not disclose financial figures – those who are aware, connected by a confidentiality agreement, and the evaluation of available information at odds at times, given the diversity of the company’s assets. We felt it more appropriate to not evaluate it at all.

Cost: $ 4.7 billion

Year of foundation : 1998

Website: mail.ru, vk.ru, ok.ru

figure: 37 % of ads in the mobile ad network MyTarget, which launched in the spring of 2015 the group placed the company in China.

Dmitry Grishin, co-founder and CEO, owns 1.84% of the company.

Mail.ru Group for the first time became the most valuable company you’ll ever need, ahead of the permanent leader, “Yandex”. Despite the crisis, mobile advertising, and advertising segments in social networks continue to grow. Revenue “VKontakte”, which the group has consolidated in 2015, has grown over the first three quarters by 41.2%. Monetizing social networks, not only through advertising – in the “Classmates” option was added to money transfers between users (joint project with VTB24). And, importantly, it makes the company not only in Russia in the autumn of her game Armored Warfare published in four languages, just one month after launch in Russia.

DS4 Crossback would be separate from the Citroen brand – REGNUM

Paris, 29 February 2016, 09:56 – REGNUM French carmaker Citroen DS cars provides the status of an independent production of the brand, according to “Kolёsa.ru».

WASHINGTON, February 29 -. RIA Novosti rocket Falcon 9 could not start due to an abnormal termination of the launch, the reasons not yet known, announced the launch of the organizing company SpaceX.

start was to be held from the spaceport at Cape Canaveral (Florida) at 03:21 MSK, but in the second, when the rocket was supposed to start, the control center gave the command to abort the launch then the engine went out.

As the leading broadcast, all prescribed in such a case, the procedures were carried out, the rocket and the launch pad were not injured, the fire was not.

The SpaceX stressed that the rocket as a result of the abolition of the emergency start is not affected. The company decided not to make a new attempt today and start to move. The decision on when the next attempt will take place will be taken after further analysis of the data.

SES-9 created by Boeing and is owned satellite operator SES. It is designed to provide communication signals in North-East Asia and Indonesia, as well as communication between ships in the Indian Ocean.

The launch was due to the device take place more than six months ago, but was postponed due to the crash in June Falcon 9 rocket for sending cargo to the ISS. Recovered after the June accident in January SpaceX conducted two successful launches of the Falcon 9. However, SES is clearly not lucky: SES-9 satellite was supposed to go into orbit on Thursday, but the launch did not take place because of the weather, the day after the launch was canceled technical reasons. On Monday, the estimated start time was postponed by half an hour due to the ship’s entry into closed at the time the “safe zone” in the Atlantic Ocean.

Life on Earth came from space – the scientists – Commander

This suggests that organic life on Earth came from space. To such a sensational conclusion was made by Russian scientists who have studied the meteorites and found there microorganisms, whose age exceeds 4 billion years. According to professionals, the solar system, including our planet, a few billion. Years ago, I was just beginning to take shape, so the homeland of microbes found in the meteorite to be found far beyond its borders, and it is still possible, and beyond the Milky Way.

Experts from Russia suggested that the origin of life on Earth may be due to the emergence of micro-organisms on the planet, who came from outer space. Scientists have conducted a detailed study of meteorites, which showed that the duration of the existence of certain microorganisms coincides with the age of the Earth, which allows to draw conclusions. Tiny organisms appeared on the planet about four billion years ago, just at the time when the solar system began sformirovyvaetsya.

«The whole solar system is, in fact, our planet, in those years was just beginning to take shape, but because the home these “fossilized alien from outer space” should be sought, we believe gde-to abroad “, – said the head of the Paleontological Institute of the Russian Academy of Sciences Alexei Rozanov Borisyak.

« not the planet, and, say, there were some bodies that had puddles, lakes, rivers, shallow sea, there lived these things, “- shared his thoughts Academician Alexei Rozanov, director of the Paleontological Institute of the Borisyak RAS

Inside the meteorite. under an electron microscope, scientists discovered protozoa. When Academician Rozanov presented his fotodokazatelstva, doubts about the existence of extraterrestrial life have disappeared without leaving a trace.

The bacteria can travel cosmic distances inside comets, while in a frozen state. This was confirmed by experiments in Antarctica, in permafrost and in the open space (micro-organisms have been found in cosmic dust settled on the ISS trim), although earlier it was believed that radiation and temperature extremes are harmful to all living things.

Samples Space dust were tested in the laboratory and compared with terrestrial samples. It turned out that in Earth orbit, there are the so-called extreme bacteria that live in the world in geothermal sources and even volcanic lava.

According to the academician Rozanov and his colleagues, the Earth was “seeded” by microorganisms as a result of massive bombardment comets still at an early stage of its development. Organisms from the weathering crust are older than 2.5 billion years. This suggests that the land was inhabited by organisms as soon as it was formed

Meanwhile, European astrophysicists also discovered evidence of cosmic origin of life. In a gas cloud, which is located in the center of our galaxy (26 thousand light years from our planet), have been found special molecules that are part of the DNA

China will launch a second orbital module “Tiangong-2″ in 2016 – RIA Novosti

BEIJING, Feb. 28 -. RIA Novosti, Ivan Bulatov China plans in the third quarter of 2016 to launch the second orbital module “Tiangong-2″ (Tiangong-2), transfers on Sunday, Xinhua news agency citing sources.

it is reported that this module must be in the future to dock with the cargo spacecraft, scheduled for launch in the first half of 2017.

In early January, the State Corporation China Aerospace Science and Technology Corp. He reported that in 2016 planned 20 launches into space. It was also reported that the launch of the module “Tiangong-2″ will focus on life-sustaining technology testing for future space station.

As reported in the newspaper China Daily citing government sources, China plans to launch the main module of its space station 2018 for testing of appropriate technologies. It is planned that the plant will begin full operation in 2022.

China’s program for space exploration launched October 8, 1956. In April 1970, China put into orbit the first artificial earth satellite “Dongfanghong-1″ ( “East Is Red-1″). The first space flight of Chinese astronaut took place at a manned spacecraft “Shenzhou-5″ in October 2003. The first output of the Chinese astronaut into space occurred at the end of September 2008, during the mission of the ship “Shenzhou-6″. The first Chinese female astronaut – 33-year-old Air Force Major Chinese Liu Yang – visited in space in 2012 on board the ship “Shenzhou-9″.

The first-class Chinese spacecraft orbiting station “Tiangong-1″ (Tiangong-1) was launched in September 2011.

Scientists have studied the impact of teleportation in the human brain – TVNZ

American biologists and programmers team from the University of California conducted an unusual experiment. Scientists have studied the impact of teleportation in the human brain.

As in the real world teleportation is not possible, the researchers offered volunteers to take part in a virtual displacement. To this end, the three participants in the experiment, patients with epilepsy, wearing special helmets through which they could monitor the changing environment around them. Scientists at this time to track changes in the brain of subjects with special implanted electrodes, the website of “Free Press»

The study experts found that the rhythm of the vibrations of the hippocampus -. The brain area responsible for emotion and human memory – changed its character during the images change. Because of this, scientists were able to confirm that the hippocampus might act from the outside.

Such results, according to researchers, can be useful in developing new ways to treat epilepsy.

Russia and the United States have made a revolutionary discovery in the field of nuclear physics – Ghhauto: Russian top stories

27.02.2016 14:14

The Russian and American nuclear physicists of the DZero collaboration announced the discovery of an exotic “rainbow” particle consisting of four quarks all four of their “color” , RIA Novosti

DZero Collaboration, which is working with the Tevatron detector, announced the opening of a new, unexplored before, exotic particles – Tetraquarks containing a quarks all four “colors”, says the article, which is published in the electronic Cornell University library.

The American collider Tevatron, which was built in 1983 in Illinois, was the most powerful accelerator in the world up to the launch of the Large hadron collider – the energy of the collision it was about 2 teraelectronvolt. Five years ago, the accelerator was stopped, but now physicists have completed the data analysis, which for 10 years were collected by detectors CDF and D0. These detectors monitor the results of collisions of protons and antiprotons.

The international team of physicists, including a number of Russian scientists from Moscow State University. MV University and institutes of the Academy of Sciences, has presented today the results of analysis of the data, which were collected by the detector D0 for all the work the Tevatron when observing the collapse of the rarest of particles – so-called “strange” B-mesons

According to modern ideas, everything. elementary particles consist of small objects that physicists call quarks. Protons, neutrons and other “heavy” particles called baryons contain three quarks. Their smaller cousins, the so-called mesons contain two elements -. “Normal” quark and antiquark, the basic component of antimatter

As scientists tell us, the data accumulated in recent years, the LHC and the Tevatron show that ” soup “of elementary particles, which are produced during collisions between ions and protons in these colliders, can occur not only classic mesons and baryons, consisting of the three” building blocks “quarks, but also exotic and Tetraquarks pentaquarks.

Scientists from the collaboration DZero opened data Tevatron signs of unusual “rainbow” Tetraquarks X (5568), consisting of quarks of all four colors – “top” quark, “lower” anti-quark, “charming” quark and a “strange” anti-quark. This particle has a very large mass – it is heavier than the recently discovered at the LHC “diabolical” pentaquarks, despite the fact that in her one quark less

Such a device Tetraquarks how scientists explain, making them more confident. the existence of these particles than in the case of pentaquarks and other “candidates” on the role of the “quartet quark”, since all they have to contain a quark and an antiquark of the same color. This has led many physicists to believe that other particles are in fact a kind of “molecules” of two mesons, and not uniform or penta Tetraquarks

The existence of these particles, scientists have no doubt -. The statistical accuracy of the opening of five sigma , which is equivalent to a random error or malfunction of the detector in one case, six million attempts. Further study of the X (5568), as participants DZero hope, will help you understand how to construct the particle as it decays rapidly and any other Tetraquarks exist about the possible opening of which physicists say in the last 3-5 years.
