whitewashed house, if you go to someone else's field, willows and poplars will come to you from ukraine. hello everyone, with you andrey tsvetkov and these are the details of the voice of america project ready to embrace the immensity and at the same time study every little thing in the world of science, medicine and new technologies. watch today: robotaxi in the desert, find out why arizona is becoming a leader in the implementation of self-driving

cars. snow guard. we will tell you why a seventy-three-year-old scientist enthusiast has been measuring the height of the snow cover in colorado for 50 years. from waste to innovation, we will show how express tests are created from plastic waste from used chewing gum. in recent years, the state of arizona has become one of the us leaders in the world in the implementation of autonomous cars. companies like weim and uber have chosen arizona as a site for the development and testing of the latest driverless control technologies. has already transformed the transport system. in the state capital of phoenix, for example, anyone can order a real robotic taxi. about what is the reason for such a large number driverless cars in arizona, when there will be more autonomous vehicles on american roads than regular cars with drivers, we will learn from our story. residents of the capital of the state of arizona phoenix have long been surprised by a passing car behind the wheel, which will not have a driver. these cars are practically no different from regular ones. on the roof of some of them

the united states, which has implemented an executive order allowing testing the introduction of driverless cars. according to statistics, about 600 of these were actively tested on our roads vehicles, dozens of companies developing driverless vehicles are testing here, for example, the cruise from general motors. we have very good conditions for this in terms of infrastructure, very good roads that are carefully maintained, good markings, and also excellent weather, more ...

in an area covering about 466 km. now driverless taxi companies are gradually starting to conquer the red and highways, motorways, and not just stick to ordinary roads in the city with fairly low speed limits. however, not all city and state residents feel comfortable enough to ride in such a taxi or even drive parallel to it in their own car in traffic. according to zhal, driverless cars will enter our lives everywhere in 6-10 years and this will happen gradually.

tesla recently made the fsd system, full autopilot, available for free for a month. for almost every owner of a car of the brand. i think this is a good strategy in order to familiarize people with the technology. they will gradually accept the fact of its existence and realize the benefits it brings. at the same time, the presence of limitations, as it were, calls for caution when you get acquainted with a new technology. the level will also gradually increase. notes that the driver assistance systems that are installed in modern cars will also help prepare consumers for the changes, because the capabilities of these systems are gradually increasing: at first, motorists got acquainted with adaptive cruise control, then the car started parking for them, and then at certain speeds, it took over the steering under their supervision. so, step by step, up to full autonomy, but if different companies are developing different software to achieve this, and also using different...

we want to develop a comprehensive framework for assessing the safety of autonomous vehicles. maybe this is a simple enough explanation, but you can think of it as a driving test for autonomous vehicles cars. we need to assess the basic level of competence of the vehicle, the integration of hardware and most importantly, software, how the car responds to certain scenarios. the assessment system will be based on the various scenarios that the car successfully. goes through before it hits the public roads. the state of arizona has become, in a sense, a testing ground not only for the cars themselves, but also for the rules of the laws needed to ensure the safe implementation of self-driving cars. cars. now similar programs,

based on the experience of the capital of unmanned cars, are being launched in other states. andrey svetkov, yuri zakressky, especially for the program details. with arizona, famous for its heat and desert landscape. colorado borders with a much cooler climate with snowy winters. in the rocky mountains of colorado lives and works the seventy-year-old scientist enthusiast bilibar, who has been regularly measuring snow cover for 50 years. his research, conducted alone with equipment that he developed himself, coincide with the findings of international groups of climatologists and confirm: the climate on the planet is getting warmer, less snow falls tayton earlier. the nearest road is more than 6 km. situated high in the rocky mountains. faculty of environmental sciences immediately after graduating from rudgers university,

fate brought him to gothic, colorado, near the headwaters of the colorado river, which supplies water to the southwest of the united states. snow cover here provides. 50 years, but in principle, a person can sit and watch something like this. amateur scientists, to which bar counts himself, any play

an important role in observing plants and counting wild animals, helping modern science to understand the environment, bar's counts, which he publishes on his website, have served as the basis for many scientific papers, helped calibrate instruments for aerial snow surveys, and each year the array of data he has collected continues to grow. one of the most significant changes i have seen here over the years is that the permanent snow cover snow cover comes later, and we lose it sooner. over the last 50 years, we're talking about 11 days of shift. although modern science has a huge arsenal of tools for measuring snow cover, including satellite data, manual measurement remains the best method, scientists say. bar's data collection has always been an unpaid volunteer

job, and sooner or later he'll stop doing it, and it's unlikely that anyone will pick up the slack in the remote colorado mountain range, but scientists are hopeful that high technology will help. standard time for the moon and other celestial bodies by the end of 2026. as the race to the moon accelerates among countries and private companies, the united states is seeking to establish international norms in space. different gravitational forces and possibly other factors change how time passes on the moon

relative to our perception on earth. a white house memo says that for a person on the moon, earth clocks lose about 58.7 microseconds per earth day. having a standard time could become. a timekeeping coupon for spacecraft and satellites that require extreme precision. under the artemis program, nasa is planning several missions to the moon in the coming years. china has also announced that it intends to send its first crew to the moon by 2030, and india has become the first country to land a spacecraft near the unexplored south pole of the moon. without a single standard for lunar time, it will be difficult to ensure the integrity of data and synchronization of communications between the moon, lunar satellites, bases and astronauts. establishing a single standard of time would require international agreements, which would have to be approved under an existing pact of 36 nations called the rotomid agreement, which covers how the world's nations operate in space. on the moon. this week, scientists at the university of washington began an experiment in san francisco bay

to combat the planet's warming. in the first test of a field of research known as solar radiation modification, scientists sprayed particles of sea salt. computer modeling has shown that releasing substances such as aerosols into the sky can help change the albedo of clouds, or their diffuse-reflective properties, causing less sunlight to reach the... earth's surface, the experiment, which was not announced to the general public in advance, will last until the end of may. the very concept of changing the level of solar radiation is controversial in the scientific community, since, according to critics, such human actions could change weather patterns and limit the productivity of fisheries and farms. geoengineering also does not solve the main problem of climate change, namely the use of fossil fuels. sweden previously tried to implement such an experiment, but a group representing indigenous peoples succeeded in having it banned. the total solar eclipse on monday , april 7, will be a wonderful opportunity for

scientific discovery, thanks to new spacecraft and telescopes, as well as a unique the position of celestial bodies. the moon will be very close to the earth, which will provide a long period of darkness, the sun should be more active with the possibility of sharp bursts of plasma. portland physics professor toby dietrich is planning a modern version of the eddington experiment. the experiment was first carried out during a total solar eclipse in 1919 by a group of scientists off the coast of africa testing the general theory of relativity. then the english astrophysicist arthur eddington , using photographs of stars, confirmed einstein's theory. albert einstein suggested that gravity is not an attractive force acting between bodies in space, as newton believed, but a manifestation of the properties of space-time, which is deformed by the presence of mass energy in it. the deviation in the position of the stars that eddington managed to photograph in complete darkness around the moon-sewn sun was close enough to the calculations of general relativity and

twice as large as newton expected, explains physicist toby dietrich. april eclipse will start in the pacific ocean and make landfall in mazatlan, mexico, pass through sijas and 14 other u.s. states, cross canada, and emerge into the atlantic at nofoundland. those outside the nearly 200-km-wide shadow will see a partial eclipse. u.s. researchers have discovered that dangerous cysts in polycystic kidney disease , or pkd, can be prevented by introducing a single normal copy of the defective gene. they also found that a class of compounds called glycosides can counteract the negative effects of the defective gene in pkd. the findings could pave the way for new therapeutic approaches to treating polycystic kidney disease, which affects millions of people worldwide. scientists have used gene editing and 3-d models of human cells to study polycystic kidney disease. it is a life-threatening inheritance. the disease occurs when a faulty gene is present, causing the microscopic

tubes that run through the kidneys to expand like water balloons and form cysts that later displace healthy tissue, leading to problems with kidney function and kidney failure. most people with polycystic kidney disease are born with one healthy copy and one defective copy of the gene in their cells. the study, supported by the us national institutes of health, is published in the journal selcel. volcanic eruptions are a process that even modern science has a hard time predicting reliably, and in order to make predictions easier and more accurate, a group of scientists in alaska have developed a new approach to storing and analyzing volcano data. the technology has already been tested in practice, when the long-extinct edgecombe volcano in alaska began to show signs of activity. the extinct edgecombe volcano in alaska has begun to show signs of active.

soil changes around their base in recent years. the collected data is sent to local internet servers, where it is then analyzed. however, working with such large files can be time-consuming, thanks to the new system, specialists monitoring volcanic activity, can now store and process information in the cloud, which significantly reduces the time it takes to operate and allows for faster updates of volcano information. geophysicist max enders notes that this is especially true in alaska.

i think in many ways we are almost always on the cutting edge. using cloud storage to automate the processing of volcanic data improves security, says geophysicist michael poland. this brings us closer to creating a kind of an international, global virtual observatory capable of providing data and analyzing results automatically and in real time. the new technology allowed the alaska volcano observatory to more quickly conclude that echcombe's sudden activity did not pose

an immediate threat, but new seismic sensors were installed on the volcano to more closely monitor its activity. phil dirking, alexey gorbachev, sergey dagotar, specially for the program details. death valley national park is known not only for being one of the hottest , driest places in the united states. sometimes it becomes a film set for movies about space travel, or, even more interestingly, a testing ground for real spacecraft. evgeniya dullo investigated what makes this place so attractive to explorers of distant worlds. death valley in the mahavi desert in california is known for its extreme climate. in 1913 , the highest temperature was recorded here the highest air temperature in the western hemisphere, +56.7° celsius. it also has an unusually dry climate. in addition, death valley is home to the lowest point in north america. the sad name

of the valley, which remains with it to this day, was given to it by europeans who wandered here in the 19th century. and during the gold rush of 1849 , gold prospectors got lost accidentally ended up in the valley, where they were stuck for some time, one member of the expedition died, when they finally managed to get out of here, one of the gold prospectors turned around said, "goodbye death valley." death valley is not for humans. in the 1970s, this idea took on a new meaning when extreme climate conditions became of interest to... space explorers, who began testing their developments here before sending them beyond the earth. nasa's viking mars probes were tested here in the 1970s, and the spot where viking landed on mars is very similar to the elevation here in death valley, which is why it was named mars hill.

nasa engineers also recently tested the perseverance rover, flying through the valley and teaching the rover how to land on mars. nasa astrobiologist razal babana korsi descends into the ubihebe crater, located in the northern part of death valley. on mars, she says, in the first billion years of its existence there were large lakes, which, due to climate change, over time decreased in size and then disappeared. at that time, the red planet looked like this crater, in which, due to recent rains formed a small temporary lake, a very rare phenomenon here. this is a place where there are many climatic contrasts, it can be very sunny and very cloudy at the same time, cold and windy or hot and calm. on early mars, the climate was also extreme, a small amount of moisture that evaporated very quickly, the same thing happens in the valley of death.

razalba studies the behavior of microbes with a very short life cycle, they need only a few hours of moisture to appear light. die. these dormant microbes love water, not like algae, which are inactive until they have access to water. this is very interesting, because something similar could happen on mars. by studying this, we can find out if latent life still exists there? the metabolic activity of the microbes here manifests itself in the bubbles that form on the surface of the lake. fossilized. traces of bubbles - says rasalba, have been found on mars. death valley with its unusual geology climate attracts not only scientific researchers space, but also hollywood directors, science fiction writers. such films as star wars and the twilight zone were filmed here. evgeniya dulho, sergey dagatar, specially for the program details, death valley, california.

used chewing gums have found a new use. researchers from scotland have learned to produce express tests from recycled chewing gum and plastic waste. the need for them is huge. every year, billions of such tests are used worldwide to detect covid, maleria or diagnose pregnancy. researchers in scotland have come up with an unusual way to combat plastic waste, producing disposable rapid tests from used chewing gum and waste plastic. billions of rapid tests are produced worldwide every year. many have used such strips to test for covid, they are also used to diagnose pregnancy or certain diseases, such as maleria. scientists at the university of erio wata believe that...

per year, these are not only tests for covid, but also pregnancy tests, such rapid tests infectious diseases, they are also used in veterinary medicine, all of these test strips are made from virgin plastic, and we wonder if they have to be made from virgin plastic, could we... from virgin plastic production in this particular case. in addition to eliminating the carbon footprint of chewing gum, the team of scientists were also able to create demonstration strips using four other types of plastic made from recycled materials, including parts of discarded refrigerators, material derived from limestone and biomaterials. we have produced five demonstration test strips, three of them from...

that the use of these test strips will start a debate we hope, about the regulation of the economic component and consumer acceptability of these new materials to ultimately reduce the carbon footprint of plastic production by 30-50%. plastic used.

decision to test its rapid test prototypes to ensure that they work as effectively as tests made from virgin plastic. these were details, we will once again look together with you into the world of the future in a week, bye. this film about two extraordinary women, about the life of marina tsvitaeva in emigration to the czech republic in the early twenties of the last century, will be told by galina vanechkova,

will tell about why tsvetayeva decided to return to the soviet union. and also about how her experience of life abroad can help new emigrants, those who were recently forced to leave their homes due to russia's attack on ukraine. hasan from uzbekistan, tashkent, a pianist with a musical education, but in his homeland he says he was not engaged in music, but in business, he sold furniture, the business failed, in 2021 he flew to latvia. he chose latvia because it was the most accessible and cheapest option, where it is possible. not only to business, as his father wants, but also to the spanish language.

8 years, endlessly long 8 years, we did everything possible so that the situation was resolved by peaceful, political means, all in vain, if i remain silent today, then i will not be able to sleep, i'm not afraid to go back to kharkov now, i'm afraid to wake up under the russian flag, well , this is russia and ukraine, yes, this is me and my daughter, you don't recognize any...

because we have children, we need interaction in any case, well, there is no point in this marriage anymore, i can't be against going against my homeland, he is putin, our father, in general, he watches tv all the time, and i sit on the internet, well, and we somehow parted in different ways, well, rooms, there is a photo, trivial, no, this is not russia, everyone our dialogue is going on with some bile, she doesn't believe me, she doesn't believe our family, she's on the ukrainian side, and there's no support from her, it's gone too far, it's impossible to convince her, she doesn't listen, she immediately switches off, says: then i won't communicate with you, mom at all?

italy is a country of long-livers in europe, and over the past 30 years, these long-livers have increased here 10 times. 92, soon there will be 93, let's go pick nuts, here with retirement people begin a new youth. when we left i've seen paris, in cafes, beauty salons, hotels, sanatoriums, universities. the curious ding takis and his best friend the porcupine have a special bond. a rare case in the lubis predator park. daniel, the little lion cub, wants more milk. barney, the barn owl chick, will be visited by the vet and have his blood drawn. the brother and sister sold their car to take care of the cheetah and open their own shelter. and this family of big-eared foxes has a special passion for food.

nannies for the beast. i'm not afraid to go back to kharkov now, i'm scared to wake up under the russian flag. russia and ukraine, yes, that 's me and my daughter. everything they did, they did right. we can't be on the enemy's side. maybe this isn't a special operation, it's a war. no one supports me. and there's no support from her. then i won't talk to you. the parties to the conflict will take the necessary measures to ensure that children under 15, orphaned or separated from their families as a result of the war, are not left to their own devices.
