large-scale projects, modern technologies, new horizons, russia of the present and future, touch all the achievements at the main exhibition site of the country. 131 expositions, business events, lectures, fairs, concerts and dozens of other events, everything that russia admires, immerse yourself in an incredible atmosphere of pride for your country, come to the russia forum exhibition.

an important step has been taken in building a closed fuel cycle nuclear power industry in russia. the world's first power unit of the beloyarsk nuclear power plant operated at full power. using innovative fuel due to the floods of uranium and plutonium. the plutonium accumulated during the operation of the reactors was considered dangerous radioactive waste. and now it is becoming fuel for a new type of fast neutron reactor. as a result, we consume less uranium, there is also less radioactive waste, and its toxicity is significantly reduced. what other breakthroughs are russian scientists preparing for us? let's find out from this issue of the science program. break. or build how

unknown gene functions are studied, incredibly interesting to understand how a constructor called a mammal works, life outside of science, young scientists about themselves and the world around them, i would recommend that the most fearless people take up science, that is, those who are confident in themselves, who know that they can achieve some kind of success, smart technologies in the world of sports, how to become faster, taller, stronger, look for a football player, he was closed, but... the chinchilla is a cute animal, similar to a favorite plush toy from childhood, they are often compared to guinea pigs or domestic rats, but in some ways they are much closer to humans than to their own relatives of rodents. for example, some organs of a chinchilla are very similar in size to a human and other biomechanical characteristics, so the animal has become indispensable. it turned out that the chinchilla

’s ears, in particular the eardrum, are as similar in shape and structure as ours, which is why it has become an ideal model for solving complex problems. bioengineering and medical ent problems. my professional dream is that all our developments will be in demand in medicine and benefit patients, because this it is very important that you...

those implants with which we close the hole in the membrane, their mechanical characteristics a priori cannot correspond to the biomechanical properties that a normal membrane has. what was needed was a fundamentally new type of implant that would not require membrane preparation and would be as close in properties as possible to natural material. it is a collagen membrane on which there is a gel containing stem cells. later, with this bioequivalent, like a doctor’s patch will close the perforation in the membrane, within a month it will be overgrown with normal tissue. but first, the implant needs to be printed. the very first layer, and we call it biopaper. in essence, these are collagen matrices. from these pieces of biopaper, we usually...

cut out different shapes that we need for the eardrum, these are circles with a diameter of about half a centimeter, in fact, this serves as a substrate for us, on which we are already bioprinting. special bio-ink is used for printing, this hydrogel based on natural polymers with a very unusual filling. in our case, these are mesonchymal stromal cells of the human gum, and we use them primarily in order to increase the efficiency of regeneration in the overgrowth of the perforation of the eardrum; when they are placed in the area of ​​the defect, they begin to disappear, accordingly, more cellular material appears in order to it's all overgrown. by setting the printer to the correct settings, you can. print not only the implant, but also other much more complex shapes, then how new is your technique, you take this bioequivalent, a matrix, yes , on which stem cells are applied by bioprinting, and then the operation takes place, yes, you introduce it into the perforation zone, of course, we remove the dead edge, that is,

the dried epidermis, and just we actually apply it, regeneration processes take place within a month, but complete ones, that is, this happens for up to approximately 3 months. now we can really look at it visually, in fact, we see that there is a membrane, white is coming fibrous edge, in the center, the handle of the hammer, and we do not see any traces of perforation and collagen residues, accordingly, the ear has already cleaned itself, just as earwax cleanses, another very important point, our patient, taking into account the fact that she still had a chinchilla, she she let me look at it, it means that it doesn’t hurt, it doesn’t hurt, it’s unique. the method of restoring the eardrum is not the only innovation. in the laboratories of the center for innovative collagen development, scientists have created an artificial cornea of ​​the eye, which is produced using a unique technology. experts came up with the idea of ​​treating collagen with electric current, resulting in a product that

combines two main characteristics - transparency and strength. the cornea is now being tested on rabbits; their eyes are in many ways similar to humans. the rabbit underwent a partial operation - keratoplasty, so far the rabbit is doing well, he is active, what is the know-how of such an operation, patients are usually given a donor cornea, but only one out of 70% of patients receives a donor cornea, because the demand is significantly higher supply, so there is a demand for artificial corneas. myth one: if both parents have some kind of pathology, then the child will definitely... inherit it, of course, all this is determined precisely by what part of the genome the parents pass on to their children, and with us usually, not always, but usually, genes are in two copies, then, in general , you need to get

broken parts, in fact, of this gene from both dad and mom. this is, let's say, an extremely rare situation when dad has two copies of a gene, one broken, the other functional, mothers have two copies of the gene, broken, the other is functional, that is, there is not a hundred percent probability, but a twenty-five percent probability that a child may have a genetic disease that results from the combination of two broken genes. myth two: there is perfect dna that will give humanity a golden era. we need to understand that our genome is our response to constantly changing conditions. there we have two constant opposite components: the desire to preserve the genome, yes, its the conservative part, and the desire to change it, the component, let’s say, mutational, that is, this is a way to still put diversity in our population, this is

what allows adaptation to constantly changing conditions, since conditions are constantly changing, we, like and plants, like all living things. in the womb and this is about your interaction with the child, and of the child with the outside world and with you, in particular with his relatives, and this is how character is formed, although there is certainly genetic component, in people who have elevated levels of hormones

, well, whatever one may say, they will have one predisposition, they will be more emotional, scientists also make mistakes, but fortunately they are able to admit it, so, for example, it happened with the concept of junk dna. initially , this term was used to describe genomes whose functions were not understood. they were considered useless information accumulated during evolution in the dna code. but nature doesn’t do anything for nothing, this became obvious when scientists have understood the purpose of previously rejected genes. now they are used to study the mechanisms of aging, body protection, or susceptibility to various diseases. similar work, for example, is successfully carried out at the research institutes of moscow state university. in total , about 20,000 genes are known, some of them have been studied literally inside and out, but most have not been characterized in any way. and these are precisely the unknowns. we collaborate with medical geneticists who look for

mutations in patients that they suspect may be the cause of the disease, but they can't say it for sure because they can't do the experiment. the study of a gene is based on the example of its breakdown, in order to understand its function, why exactly it is valuable to the body, it needs to be damaged and see what happens when this gene is not present, experiments are carried out on... these are mice in which the gene is turned off leptin. leptin is a protein that is produced by adipose tissue, which tells us that it’s time to stop eating, we turned it off, and the mice don’t understand that they have a lot of fat and continue to eat, eat, eat and become such balls. here we want to test the compounds that we find on them and see if they lose weight? in order to get a mouse with the gene turned off, researchers work with

rodent eggs. before us is a system for micromanipulation of eggs, now oleg inserts a capillary blank for microinjection of the genetic editor, in order to make a very thin needle with which you can pierce the egg and introduce the genetic editor into it. this one is very thin. capillary needle, solution is placed a genetic editor aimed at inactivating a gene. scientists use the same method to recreate genetic mutations that doctors find in people. essentially, these are duplicates of real patients. but researchers call them models of disease susceptibility. they help identify the disease at an early stage and possibly find a way to treat it. well, in fact, now the situation in biology is similar... to what happened in geography during the time of the great geographical discoveries, when the general

outlines of the world map were known, but at the same time there are still quite a lot of blank spots, there is still a lot to discover, in order to understand how we function, how genes determine the development and functioning of humans and other animals, we must understand the function of all genes. thanks to the success of our scientists, the collection of such studies will be constantly updated. my name is mark jain and my surname is non-standard of the religion jainism, this is an offshoot of hinduism, my father, he is from india, my mother, respectively, she is from russia, she is also involved in science, that is, in some kind of stepe family, i think this is the best.

in the patient, because it is known that this procedure is quite expensive, it cannot be done often due to the hormonal load, it cannot

be done often also because the number of high quality embryos that could be transferred is limited, in some patients it is simply not possible to obtain a lot, and we want to create a technology that could , even before the start of hormonal therapy, even before thawing the embryo, help to draw a conclusion whether it is worth doing this at all now procedure or is it better to save this embryo, not to expose the patient to unnecessary hormonal load, do it in the next cycle, when... this technology is based on identifying extracellular dna fragments that contain mutations characteristic only of tumor cells. we work with diseases such as thyroid cancer, bladder cancer, pancreatic cancer, and brain cancer. in case of brain cancer, it is often impossible to take biomaterial from the tumor. in such cases, our technology can be useful, we take the liquor in it and find here

these intracellular fragments of tumor dna. and i hope to see these projects in the near future. now i am also a teacher at the department of medical microbiology and immunology, communication with students keeps me energetic every time, because it’s not that i see myself in them there, as many say young, no, but it’s just fun. so, it’s the yellow team’s turn, choose a category.

i also need miniatures, almost every evening, at least half an hour, i turn on the lamp, some calm music or about something socially useful, i paint miniatures , i have a dog, his name is giml, named after the unknown gnome from lastilino rings, our adult life, you mostly sit at the computer or at the laboratory table or somewhere else, and the dog is so good an incentive to leave...

at moscow state university, for example, there is literally every month or every 2 months some kind of competition where you are tormented by leafing through the list of winners, that is, they actually give incentive payments to many young scientists for annual assignments and incentive payments simply for articles in general, for everything, i think in other universities the situation is approximately the same, and i think those people who complain that it is impossible to live in science, they simply do not even participate in these competitions, i would recommend taking up science for the most fearless, that is, those who is confident in himself, who knows that he can achieve some kind of success. a real olympic medal is approximately 500 grams of gold and silver of the highest standard. but the most important thing is confirmation of the honorary title of olympic champion. the lifelong goal of any athlete is to have such a medal on his chest. but what is behind each medalist? years

of training, hundreds of competitions, dozens of coaches, but also those who are always forgotten: thousands on... artificial turf? the answer to this question is well known at spartak academy. now classes are being held here on the new system in the smart arena. the simulator itself consists of projection screens. projectors and high-quality cameras that track the player's every action. and analyzes, giving the analytics in real time, how many passes the player has made, how quickly he makes decisions, how skilled he is evaluate space and much more. the training is individual, the player improves his skills alone with the coach, receiving a variety of tasks, mainly on technique and spatial thinking. it was closed, but

nothing. okay, twist, twist your head. psychologists also take part in the development of the simulator, so some of the tasks are aimed at developing cognitive abilities. for guys, this is the first reaction. now, the second thing is speed of thinking. and of course, strength, in general, probably, passing strikes, accuracy. you understand how, because in football - this is important. you know, here. i bring goalkeepers here, this is my simulator and i even train goalkeepers, i still , in general, i think it’s the best one for us at the moment. smart for sports is not only the arena, but clothing, training. at a minimum, such a suit should increase the endurance of athletes. the suit allows us to use it directly during each workout and get the effect here

now. faster activation of muscles , faster warm-up and preparation athlete to training load. it's all about the magic springs. these are elements with a given degree of elasticity , a kind of applicators that have a targeted effect on the muscles. they were called pillboxes. the technology of such point compression was developed in the biomechanics laboratory of the institute of medical technology, this is, in principle, a unique idea, that is, we created a metal, we make it ourselves , then as a result, we make springs from this metal that catch micro-vibrations from the surface of the body and return them back, as a result this the effect of micro-point massage occurs and from this... this improves blood supply to the microcapillary, let's check it in another training session: the legendary dynasty of bobsledders are wearing special suits, you know, when you do enough intensive volume

training, at the end, after an hour and a half , there is such an energy decline, you begin take it, as if i don’t really want to, here it’s the other way around, yes, that is, for me it’s the other way around, after an hour of training i have such an energy boost, i can say that this is due precisely to this equipment,

what general position are we currently in in the world, that is, our russian developments, we are keeping pace with world sports, today we are in fairly leading positions in the field of world sports, in the field of research, sports education, science, this is an area where it is impossible to put up any barriers with the current information security system; we need to study everything new in order to, well, constantly, as they say, be on the cutting edge.

in determining the winner. for this purpose , the first chronograph was created in the 19th century. at the beginning of xx centuries, time is already recorded with an accuracy of tenths of a second, and soon to hundredths. and in the seventies, a new miracle of technology was electronic stopwatches. it was they who allowed the swedish swimmer to receive a gold medal at the 72 olympics. he was ahead of his competitors by just a thousandth of a second.

polyethylene sliding surface for skis with additives for any weather conditions also significantly improved the results, but the most significant result, perhaps, was achieved in swimming. at the 2008 olympics, michael phelps in a special suit, significantly reducing friction, broke three world records in a week. now much of what was created for athletes has become the basis for mass production, for example, synthetic fabrics that wick away moisture well, or... modern cars, most of the inventions for which were made by formula 1 engineers. an idea for new research is not always the fruit of long laboratory work. sometimes it is enough to take an example from mother nature. siberian scientists, for example, were inspired by the structure of tree leaves and transferred it to development a unique type of microfiber catalysts. this is a completely new type of system that uses

glass microfibers as a carrier. structured in the form of a thread, they ideally provide the supply of reagents to active centers and the removal of reaction products. the researchers’ work does not yet have foreign analogues and has high potential in the field of import substitution. it was the science program and me, natalya popova. see you. what happened here on february 24-25? social networks, calls, sending fake news, contact rally, all western-linked pr agencies joined in to encourage regional

local riots. the main task is to capture the enemy people not physically, but ideologically, to bring confusion and confusion into their souls, this is the surest path to victory in the war. the content and the agenda itself are formed by hundreds of people, professional people from the state, who spend their entire lives influencing minds. i personally trained for the hipso course. there are chats where you get tasks, today we scare belarusians that they are russian. will be forced to fight tomorrow dagestanis, it means that they took to the streets, remember when they endlessly explained to us that ours is not the same country, that we should be infinitely ashamed because we are russians, this was a real hybrid war.

we will take on this case, it will be an honest detective story.

attacks of the armed forces of ukraine this was reported to the ministry of defense, two more in krasnolimansky and one in kherson. enemy losses number in the hundreds, with up to 325 militants killed and wounded in the donetsk direction alone, where the most active fighting took place that day. on in the donetsk direction, units of the southern group of troops defeated the personnel and equipment of the ukrainian armed forces in the areas of the settlements of novaya, krasnaya, kleshcheevka, kurdyumovka, donetsk.
