Intel Corporation reports that it recently received a patent for the technology of using the powers of mining equipment for processing genetic data. The authors of the idea Ned Smith and Rajesh Purnakhandran in the explanatory note describe the genome sequencing platform that will determine the order of the nitrogen bases in DNA or RNA.
Nitrogen bases are compounds that are part of nucleic acids containing genetic information. The sequence of these molecules determines what characteristics a living being has, whether it is a human being, an animal or a plant.
In the annexes to the patent it is said that the genome sequencing platform will work by determining the sequences of nitrogenous bases in the nucleic acid, algorithm Proof of Work for the extraction of blocks. After determining the genome, information about it will also be recorded in the chain of blocks.
The resources that are spent on the extraction of new blocks usually do not perform any other useful work, whereas Intel patent offers the miners to work in multitasking mode, simultaneously extracting blocks and sequencing genetic data.
The application was filed in June 2016. Now, on December 14, almost a year and a half later, the Office of Patents and Trademarks in the United States approved a patent.
We invite all comers to discuss Intel's idea and just chat in our telegram chat .
The heater is a device, without which in our climate there is no way. That the heating will turn on with a delay, then the frosts will hit the children's and will become cool in the apartment. In general, almost in every family he is, often not one. And around the heater – a swarm of myths and legends. Listen to them – just right to throw out this harmful and dangerous device as soon as possible – it's better to shiver from the cold. No, it's no better: we remembered the most persistent "heating" misconceptions and explain how things are in reality.

The truth about burnt oxygen
Heaters (especially with a heating spiral) burn oxygen – this is perhaps the most popular horror story, which in the top for many years. And users did not invent it themselves – marketers are to blame. This they continue and continue to cultivate with the tenacity of the North Korean missile system. Below is a recent example – a screenshot from Facebook, from the page of one of the manufacturers.
Manufacturers still convince us that some heaters burn oxygen
Marketers are coming from the opposite, they say, the heater of our brand, unlike hypothetical others, oxygen does not burn. So, there are those that burn – potential customers think, without going into details. And they are mistaken – more than one heater does not do anything with oxygen, does not influence, does not work, its maintenance in the air and certainly does not burn.
Yes, oxygen is consumed in the process of burning a flame. But it is in the process of burning, and in the heater, if it is sound, nothing ever burns. So do not worry about the fate of oxygen – it's all right.
The legend about the combustion of oxygen heaters, most likely, appeared because in cheap models, in particular heat fans, heating elements (spirals, etc.) are heated to high temperatures – "red-hot", and household dust that falls on them, begins to burn – there is a slight smell of burnt paper. Oxygen, of course, with this burning consumed, but in such quantities that it is impossible to detect. In devices with heaters whose temperature is lower than the temperature at which the dust begins to burn (almost all modern ones), this does not happen.
The truth about dried air
All heaters dry air – this statement is hardly less popular than confidence in the unhappy fate of oxygen, which is unlucky to be on the same planet as the heaters. But here everything is a bit more complicated. It arose because of the confusion in terms. Saying "the heater dries the air", it means that its relative humidity decreases. And indeed it is. However, the absolute humidity of air remains unchanged. The expert explains.
Dmitry Mamontov, scientific editor of the Polytechnic Museum:
The absolute humidity (the water content in grams per cubic meter of air) does not change when the air is heated. The relative humidity measured in percent (the ratio of the real water content to the maximum possible at this temperature) is lowered. The person is mainly sensitive to relative humidity, since it is precisely it that is important for our temperature regulation, in particular, the evaporation of sweat is highly dependent on the relative humidity.
And what in the end? Heaters, as well as air conditioners in heating mode, "dry" the air, reducing the relative humidity, but not absolute – moisture in the air does not become less. But when the temperature is below the dew point, some of the moisture condenses, so air conditioners in cooling mode tend to dry (without the quotes) air, reducing the absolute content of moisture in it.
The dew point is the temperature at which the vapor in the air reaches state of saturation and condenses into moisture (dew).
In general, two concepts should be divided – the relative and absolute humidity of the air. The statement "heaters dry air" makes sense only when understanding the difference between them.
The heater at work reduces the relative humidity of the air, while the absolute remains unchanged
The truth about the "rays of life"
Recall how infrared (IR ) heaters. Infrared radiation, like the sun, does not warm the air, but surrounding objects: floor, furniture, walls, even, within reasonable limits, people with animals. And already from them the air warms up.
To make you buy IR heaters better and better, marketers have come up with a concept such as "the rays of life". Like, there are IR heaters with a wavelength of 9.6 microns, which is supposedly cool and correct, because it coincides with the frequency of the person's own thermal radiation. Hence, such external radiation is intensively absorbed by the body, it penetrates deeper than radiation with a different wavelength. The effect, sort of like, more effective.
Infrared heater does not have any miraculous properties, does not emit "magic rays of life"
But this is, to put it mildly, an exaggeration. Physics does not know the laws that would prove that the energy emitted by one source, somehow penetrates deeply into objects, if the wavelength of their radiation is the same as those of these objects or organisms. And that in this case a person somehow warms up faster, better perceiving "the same as his" thermal radiation.
Energy, as is known, can be transmitted (spontaneously) only from a warmer body to a less heated body – this is the second beginning thermodynamics. The maximum absorption of infrared radiation by the human body occurs in the range 0.7 – 1.4 μm (water, from which 60-70% of our organism consists, just the best is radiation with a wavelength of 1.4 μm). And all that marketers call the "rays of life" (9.6 microns), heats only the upper layers of the skin.
Dmitry Mamontov, scientific editor of the Polytechnic Museum:
The wavelength is directly related to the temperature of the radiator (this is based on the work of the thermal imager ). The maximum wavelength of 9.6 microns corresponds to the temperature of the human body. It's not much use from a heater with such a temperature.
The truth about the efficiency of heaters
Often in advertisements you can find the phrase that "the efficiency of this heater is close to 100". This is not a lie – indeed, the overwhelming majority of heaters used in everyday life work with very high efficiency – how much energy is consumed, and so many will turn into heat.
Energy losses during operation of most modern heaters are minimal
Yes, when a heater with a closed heating circuit operates, electromagnetic radiation occurs. It consumes part of the energy consumed from the grid, but these losses are so small that they can be neglected. In general, the point is that it is very difficult to find a working heater, the efficiency of which will be significantly below 100%. The high efficiency of most heaters is a given, and not the achievement of individual producers.
The Truth About Power and Square Meters
Many modern heaters have a choice of power level. It would seem that there is something wrong here. I wanted – I chose the maximum: the heating will be more intensive, the room will warm up more quickly. Or use less power. However, in many models of heaters the power with which they work is constant.
By turning the thermostat knob, only the ratio of the time of operation of the device and its "rest" is regulated – the heater works as discretely (turns on and off), such as a microwave oven or refrigerator (non-inverted). This should be understood and monitored for the correlation of the power supply capabilities with the maximum power of the heating device.
The power of the heater, as a rule, is always the same, and many factors need to be taken into account when calculating the area served
There are, however, heaters with several heating circuits, and they are switched on separately. That is, not only the thermostat and the timer, namely the separately operating heating elements – in this case it is really possible to talk about the adjustment of the power of the device.
In the characteristics of any heater, information on the maximum area of the room must be found, for which it is designed. For example, 15 or 20 m². This, of course, also greetings from marketers. Characteristics invented, so that customers do not suffer with watts and kilowatts.
The reference point is 100 W per 1 m ². But, alas, with such averaged approach, the type of heating element is not taken into account, the features of the room (heat loss in it), as well as the temperature outside the window – all these factors affect the work of the heater and the heating efficiency of the room in different degrees.

The Alphabet division under the stamp X developed the technology of Free Space Optical Communications (FSOC), a new type of optics, thanks to which it is possible to connect large rural regions to the Internet.
Now Alphabet signed a contract with the Indian state of Andhra Pradesh, within which the state purchased 2,000 FCOS devices. They are small boxes that are attached to poles with mobile Wi-Fi points, and then communicate with each other using light rays, providing an Internet coverage area with a speed of up to 25 Mbps for citizens and up to 100 Mbps for enterprises and organizations.
Now only 20 percent of the inhabitants of the Indian state have access to the Internet, whereas by 2019 local authorities expect to connect to the Network an additional 12 million new users, among which there will be not only private individuals, but also enterprises with organizations.
FSOC technology was used by Alphabet engineers and earlier in the Project Loon project – then it was planned to distribute the Internet using special balloons equipped with FCOS devices.
The installation of FSOC on poles is much cheaper than balloon launches, the effect is just as good, so the Alphabet engineers team will soon arrive in India to implement the project.
The new development of Alphabet X will connect rural areas of India to the Internet Vyacheslav Larionov

On the streets of our cities we are accustomed to seeing many plants that perform, as a rule, purely decorative function. But what if all this flora could be given additional functions? Say, in the daytime plants produce oxygen, and at night – light the streets? It sounds fantastic, but in fact it can soon become a reality.
In fact, such an idea is not meaningless for economic reasons, because according to various studies, 10 to 20% of everything is spent on street lighting at night produced electricity. According to the publication Science Daily, scientists have come close to creating bioluminescent plants. And such a venture may not be as impossible as it seems at first glance.
Many living organisms have the ability to glow in the dark. Moreover, before scientists could already "activate" the necessary genes in plants. For example, it was possible to achieve luminescence of tobacco leaves, using genetic engineering. But scientists from the Massachusetts Institute of Technology decided to use nanotechnology. They created silicon and polymer nanoparticles, which are able to move inside the leaves and stems of plants in a certain direction, thereby "highlighting" light. Each of the particles contains one of three substances: luciferin (which emits light), luciferase (an enzyme that causes luciferin to glow) and coenzyme A (it increases the activity of luciferase). All three nanoparticles under pressure in an aqueous medium are placed in the stomata of plants.
As a result, scientists managed to achieve the glow of the leaves of the plant, which was 100,000 times greater than that of a genetically modified colleague. The most interesting is that the glow can easily be "disconnected" by adding a compound that blocks any of the three above substances. At the moment, the maximum period of luminescence of plants is four hours, but scientists are planning to increase this figure.
Authorities in some US states offer to plant drunken operators of quadrocopters, drones and helicopters in jail and fined them for large sums, as they create socially dangerous situations, reports Digital Trends.
The festive season is coming, during which millions of people will necessarily buy themselves a helicopter on remote control, so the New Jersey state authorities, with the support of colleagues from other regions, have begun to promote a rather tough at first glance bill that will re-qualify an innocent prank in intoxicated state into a criminal offense.
It would seem that this – well, chopped the helicopter in a state of drug or alcohol intoxication, took the toy and went home. Okay, but if a user drives out somewhere wrong, hurts a pedestrian or damages someone else's property? Even small blades of flying toys that do not exceed the size of a pack of cigarettes can cause cuts and deliver a lot of unpleasant sensations, what can we say about large aircraft used for racing, aerial photography and other serious tasks?
If the bill is passed, the drunk operator of the aircraft will either be fined by the amount of a thousand dollars, or imprisoned for six months. In particularly severe cases, it is proposed to apply both types of punishment.
While the proposal of the New Jersey authorities is being considered in the Senate, and most states have not yet decided on their position, but if the law is passed, it will have legal force from the end of January 2018.
Talking about the work of Jim Keller, head of the hardware development department, Ilon Mask confessed that Tesla makes hardware and software for use in drones. Speaking of the development potential, Mask, without false modesty, noted that they will be the best in the world.
Now for its unmanned systems, Tesla uses NVIDIA solutions, including advanced hardware development, but in the press there have been periodic rumors that soon the partnership may end, since Tesla will create hardware for the UAVs themselves. It seems that Tesla will soon abandon third-party equipment.
Musk noted that stand-alone technologies running on Tesla equipment will not appear until two years later – that's when they will be available to all comers. A year later, artificial intelligence systems created by Tesla for autopilots will cope with driving far better than humans.
Telling about his own developments, Mask noted that AI in the direct sense of the word will appear in the next five to ten years, than again attracted the attention of skeptics – professionals in the field of AI have a completely different opinion, so they do not accept the forecasts of the head of Tesla seriously.
Tested a fashionable vertical vacuum cleaner, besides wireless. Make – Midea. This is a very large Chinese (and world) manufacturer of household appliances. It is worth VSS01A14P-R – 7500-8000 rubles *. Format 2 in 1 – there is a removable manual "vacuum cleaner". Details and results – in our video, as well as in the text version.
Video test of Midea wireless vacuum cleaner – the main thing in a few minutes
For uncompromising visuals, video was made about cleaning, vacuum cleaner comfort (about inconvenience too), noise and filters. The main thing, including the final assessments. Enjoy.
Details about the vacuum cleaner Midea
Midea VSS01A14P-R – the classic of the genre in the segment of wireless vacuum cleaners. Small size, nice appearance. Removable hand vacuum cleaner (in fact, the main thing – these are the features of the design of models of this format) makes the device universal, extending the harvesting opportunities.
Wireless vacuum cleaner Midea VSS01A14P-R
The garbage from the floor is answered by a turbo-brush – normal, without special "bells and whistles "- bristles on a rotating roller. Such brushes are obligatory for battery models, because they help to cleanliness by pushing garbage inside the vacuum cleaner: the suction power in most such models is still small (less than 100 au).
The suction and dropping system is cyclonic. Dust collector small – 0,3 l. Therefore, the vacuum cleaner is positioned as an auxiliary – for quick cleaning, if necessary. Garbage on the floor, in cars, flour or tea, scattered on the kitchen table. The power level is two. Battery life up to 55 minutes. That's all there is to know about him.
Removable manual vacuum cleaner: you can vacuum upholstered furniture, car salon, quickly put things in order in the kitchen
Vacuum cleaners are simple: we vacuum them. And the "garbage" loads are often extreme. We check how much they are convenient in use, that with hygienic cleaning of the dust bag, we measure noise at work, using a special sensor of fine dust – it is dangerous for humans, loves to settle in the lungs, which can cause a lot of health problems – we check the air filtration. In general, we comprehensively study the device on the test.

Cleaning . Given the large amount of debris that had to be "swallowed" during the test Midea VSS01A14P-R – he did well. Under normal conditions of a city apartment, such a vacuum cleaner load is unlikely to shine.
There were, however, some problems with garbage collection from the sofa. And not always the dust collector was full. Sometimes garbage remained in the turbo-brush (it's not about the sofa), not passing on, and spilled out when the vacuum cleaner was turned off.
The filtration (cleaning) of air from garbage is also part of the cleaning. And then something strange happened. A professional laser sensor of fine dust showed that the air from the vacuum cleaner goes worse (see video) than it goes into it. We applied for a comment to the manufacturer. After waiting a few days, they did not get an answer.
The fact that the vacuum cleaner has average filters is not surprising – they have the overwhelming majority of wireless models such. If you put the filters better, you have to increase the power, and this will reduce the battery life, which the manufacturers somehow fear, like fire. In general, allergy sufferers when using wireless vacuum cleaners need to be cautious.
Cyclonic suction technology and (traditionally for battery vacuum cleaners) the average quality of the air filtration system
Working noise is also part of the cleaning. We measured it with a household sound level meter and came to the conclusion that the results correspond to the modern "vacuum" realities – there is no overshoot over this parameter (up to 80 dB). But the tonality of the sound of the engine did not really like it.
Given the incredible severity of the harvesting test (there was very much garbage) and the strangeness with the filters, we set the fourth for the quality of harvesting .
Usability . The English word "usability" means ease of use. I did not really like cleaning the turbo brush – I need to unscrew a special plastic clip using a screwdriver: yesterday, now many competitors have less trouble with it.
Turbobrush of a classical design, but it's not very convenient to clean
A small dustbag is also not very great. For example, if the carpeting at home is a noble dust collector, it will be filled quite quickly. However, its devastation did not cause difficulties for us – everything is quite traditional here, but without any unpleasant surprises.
Otherwise, without any complaints – to weight, maneuverability, no claims management. But taking into account the moments with the brush and dust collector – also the fourth for usability .
See also: Is it worth to buy a budget vacuum cleaner for less than 4000 rubles?
Design . And here it is unanimous – the assessment is excellent. Imagination the appearance of the Midea VSS01A14P-R is not striking, but it does not irritate, which is important. Quiet minimalism of our editorial staff is like, but buyers in the store can pass by – everyone has different tastes.
We did not find any special innovations in the vacuum cleaner, so we do not put an estimate on the item of "innovation" and do not take points for " traditionality. "
Control system on the handle: power button and power selection from two levels
Final score for the test – 4.3 points . This vacuum cleaner is a strong average. Stars from the sky are not enough, but at home, without extreme loads, with easy cleaning will cope. The main disadvantages: it is inconvenient to clean the turbo brush, a small dust collector, you can not call the advanced air filtration system. Pros: light, 2 in 1 format, it's easy to clean the container of dust, nice, noise is normal. We recommend a vacuum cleaner to those who want for a not too high price to have an assistant's house for a small quick cleaning.

It's unlikely that many of our readers will use the Bing search engine as the main source of the information sought. Surely there are such people, but their overwhelming minority. Most of the users of Runet prefer to systems such as Google and Yandex. Microsoft Corporation, however, does not give up, and constantly develops Bing, introducing new features into it. For example, yesterday it became known that now he will actively use artificial intelligence to search for information.
As part of the event that was held yesterday in San Francisco, Microsoft officials announced that Bing will henceforth actively use the capabilities of advanced artificial intelligence when processing users' search queries. For example, when he answers the question, he will first find the answer immediately on several sites, and then he will choose the most popular option. If the answers differ, Bing will try to provide the user with a choice of the most popular versions, so that he can choose the option that best suits him.
The answers to queries will now be presented in the most accessible and understandable form, so that a person could read them comfortably . Microsoft employees themselves gave this example: instead of answering that the area of Syria is 71,489 square miles, Bing will compare its area to the US state of Florida. Of course, this is an analogy, but Microsoft representatives, of course, know better. They insist that they do not want to load people with numbers, but instead offer them a more vivid answer, which they will immediately understand.
The search engine will also improve its skills in comparing different concepts and phenomena. Want to know the difference between Pilates and yoga? No problems. Bing will detail the pros and cons of these two systems of exercises in the most accessible form. Among other things, the search engine will begin to ask leading questions to clarify what exactly interests the user. Well, the most important achievement is that Microsoft engineers consider a new search for images. Bing has learned to recognize objects in photos and search for them on the Web. For example, a girl wants a handbag like a movie star – the search engine will process the photo from the red carpet and immediately give out the name of the product and the link to the store.
Microsoft also announced its collaboration with the popular Reddit forum. From now on Bing will be able to search for information among the millions of topics of this resource and to provide search results to users. You can search even among the most popular recent AMA interviews (Ask Me Anything), when users of Reddit ask any questions entered by the celebrity forum. In addition to Bing, the advantages of artificial intelligence will also include a voice assistant Cortana and office suite Office 365. All of the above will be available to users within the next month.
From the middle to the end of the twentieth century, quantum physicists disassembled in a single piece the unified theory of physics proposed by Einstein's general theory of relativity. The physics of the large is subject to gravity, but only quantum physics could describe the observations of the small. Since then, the theoretical tug of war between gravity and three other fundamental interactions has continued, while physicists are trying to expand gravity or quantum physics so that one can absorb the other. The latest measurements from the Large Hadron Collider show a discrepancy between the Standard Model predictions, which may hint at completely new spheres of the Universe underlying the described by quantum physics. Although confirmation of these anomalies requires repeated testing, confirmation will mean a turning point in our most fundamental description of particle physics to date.
Quantum physicists have discovered that mesons do not decay into kaons and muons as often as required by the Standard Model. They believe that increasing the power of the Large Hadron Collider will reveal a particle of a new type responsible for this discrepancy. Although the discrepancy can cause errors in data or theory, in this case, instead of the new particle, the improved LHC will be a boon to several projects on the forefront of physics.
The standard model is a well-tested fundamental theory of quantum physics that describes three of the four fundamental interactions that are believed to govern our physical reality. Quantum particles are of two basic types: quarks and leptons. Quarks are bound together in various combinations, forming particles like a proton and a neutron. Protons, neutrons and electrons are known to collect into atoms.
The "lepton family" has heavier versions of an electron – like a muon – and quarks can merge into hundreds of other composite particles. Two of them, the lowest and K-mesons, were implicated in this quantum detective, which scientists drew attention to. The B meson decays into a K meson, accompanied by a muon (mu-) and an anti-muon (mu +).
Scientists have detected a probability of 2.5 sigma, or 1 to 80 of that in the absence of unexpected effects , that is, new physics, a more deviant distribution than observed would be produced in about 1.25% of cases, says Professor Spencer Klein, a senior fellow at the National Laboratory of Lawrence Berkeley. Klein did not participate in the study.
Simply put, the frequency of decay of mesons into strange quarks in the process of proton collisions at the LHC is lower than expected. "The catch is that with 2.5 sigma, or the data is a bit wrong, either the theory is a little wrong, or there is a hint of something outside the Standard Model," says Klein. "I would put something on one of the first two."
According to Klein, this deviation is inevitable, given the large amount of data that computers operate in operations with the LHC. "With petabyte data sets from the LHC and modern computers, we can produce a huge number of computations of different values," says Klein. "The LHC has issued hundreds of results. Statistically, some of them may exhibit fluctuations of 2.5 sigma. " Particle physicists usually wait for a fluctuation of 5 sigma before hitting the bell.
These recent abnormal observations were also not taken from the ceiling. "It's interesting how these observations correlate with other anomalous measurements of B-meson processes done in recent years," says Dr. Tevong Yu, co-author of the study and associate researcher at the University of Cambridge. "These independent measurements were less pure, but more significant. In sum, the chance that all these different measurements deviate from the Standard Model is close to 1 by 16,000, or 4 sigma, "he says.
Extension of the Standard Model
Excluding statistical or theoretical errors, Tevong suspects that the anomalies mask the presence of completely new particles, leptoquarks or new gauge bosons. Inside the lower mesons, the quantum excitations of new particles can interfere with the normal decay frequency. In their study, the scientists concluded that the updated LHC can confirm the existence of new particles and make a powerful upgrade to the Standard Model in the process.
"This would be revolutionary for our fundamental understanding of the universe," Tevong says. "For particle physics, this will mean that we raise one more layer of Nature and continue the journey to the most basic building blocks. This will be important for cosmology, because it relies on our fundamental theory of understanding the early universe. The interaction between cosmology and particle physics has been very fruitful in the past. As for dark matter, if it arises from the same new physical sector in which the leptokvark is embedded, we could also find its trace. "
Knowledge is Power
So far, scientists from the LHC have observed only ghosts and anomalies, hinting at particles existing at high energy levels. To prove their existence, physicists "need to confirm the indirect signs, and for this it is necessary to wait until the LHCb experiment collects more data on the decays of B to make more accurate measurements," Tevong said. "We will also receive independent confirmation from another experiment, Belle II, which will make itself felt in the next few years. After all this, if the measurement of the decays of B still disagrees with the Standard Model predictions, we will be sure that something outside the Standard Model plays here. "
To establish the existence of new particles, physicists must produce them in the same way as the lower mesons or Higgs bosons, and observe their decay. The fact that they did not see such exotic particles on the LHC (for the time being) means that they can be too heavy and they need more energy to produce them.
Quantum jump for the LHC
The search for new particles at the LHC does not depend on expectation. The probability of observing new phenomena is directly proportional to the number of particles dying in the collisions. "The more particles appear, the higher the chances that we will notice the right thing against the background of many other events in these clashes," Tevong explains. Search for new particles, he likens finding a needle in a haystack; it is easier to find a needle in a haystack that is stuffed with needles.
If the anomalies are confirmed, the Standard model will have to change. At the same time, the scale of energy will also increase, which will be guided by the next generation of colliders. Maybe we'll get to the dark matter too. And there, you see, we will unite all these interactions between various anomalies into a single and elegant theory.
Despite the fact that 3D printers are getting denser in our lives, they still remain rather bulky devices and do not aspire to miniaturization. However, Chinese engineers from MakeX Corporation presented the most compact 3D printer at the moment. The most interesting thing is that this printer is built into a normal backpack.
MakeX positions the device as an instrument for speeding up the printing process. For example, the printer owner can go about his business, and the printer will not even stop working. Alternatively, the printer can be used as a portable device that prints details, receiving jobs from different computers.
The "backpack printer" was presented in two variations: 100 x 120 x 100 mm and 150 x 150 x 150 mm. And both "kids" have all the advantages of more cumbersome brothers, and for printing items exceeding the size of the printer, you can use special glue. The creators emphasize that this version of the 3D printer is one of the most budgetary in the market and it can be purchased by almost anyone. But at the moment the device is available for purchase only in China. Unfortunately, it is not reported when it will appear on the shelves of other countries.
