the network is also full of recommendations bags with amber, compresses for rheumatism and arthrosis will help with sleep problems and stress, bracelets for hypertension, what does science know about this and what is amber in general , in fact, this is a petrified resin that coniferous trees emitted for several tens of millions of years back similar stones, often helping scientists due to the preservation of insects and other inclusions , are in different parts of the world. for example, colombian blue copal, but succinite is the geological name for the most common of species of baltic amber, is distinguished by the maximum content of succinic acid and natural conditions have developed. so the world's largest deposit is located on the territory of the current kaliningrad region, according to a beautiful ancient legend. once the sea goddess fell in love with a simple fisherman and the lord of the gods punished her for it by digging at the bottom with chains and destroying her amber
11:01 am
castle and now the sea carries out its fragments after a storm, indeed, amber can sometimes be found just like that right on the beach, but mostly, of course, it is mined in a completely different way. the main object on the vast territory of the amber plant is a giant quarry equipment that removes 65-70 m of waste rock to open a layer saturated with amber, the so-called blue clay is washed away by a powerful stream of sea water, and then with the help of machines and manually with glasses, the stone on the feet is sifted hold on, otherwise it's nothing. it's hard work, but i caught something. then the amber is cleaned and
11:02 am
separated into pure fractions and floats up in vats of salt water. sometimes there are unique giants weighing more than a kilogram for their volume. he probably even seems easy. well , of course, not a stone, but all the same, makhina is so impressive, especially when you know that the cost of such nuggets is already in the millions. it is interesting that amber was not always valuable, at some times they even heated stoves, but in other eras they began to consider it almost a jewel, you know why this is the gallows on the observation deck of the plant. she recalls that the authorities of these places have always strictly monitored illegal mining and the sale of amber, the current prison sentences - this is also that in the fifteenth century there was a decree that attributed violators to be hanged on the first tree that came across. now the extraction of amber is controlled by the
11:03 am
state, but illegal immigrants are still working. here it is their boats that are visible in the sea near the village of yantarny, as the locals told me. these risky people scuba dive, pompously wash out a hole at the bottom of a well with a depth of several meters and get it out, yantar often collapses, alas, and with fatal outcomes, another problem , fakes and experts. it is said that forgers are becoming more and more skillful. we were convinced of this mystery itself, walked through the souvenir shops of moscow and bought three different products. surprisingly, only this decoration, as shown, then an examination in the laboratory of magneto-optical research of the baltic federal university turned out to be with real amber, two other artificial polymers try to distinguish the original, you can at home, for example, by dipping natural
11:04 am
amber into salt water, it will remain on the surface or enlighten under ultraviolet light, the resin should fluoresce and glow inky. but all this is unreliable. and certainly nothing can be understood by eye, only certificates and proven places can give at least some hope. well, what about the healing properties of sellers often. it is said that amber heats up from contact with the body and releases healing succinic acid, which is absorbed through the skin at the baltic federal university. succinic acid has indeed revealed outstanding antimicrobial properties. sometimes even better than antibiotics. as a result , it was found that amber oil is succinic acid, they will check to show a sufficiently high antimicrobial activity against. in principle, almost all, but the microorganisms we have taken. this is confirmed by foreign studies, scientists are creating new samples of cosmetics with succinic
11:05 am
acid, the only problem is that the substance is obtained, as a rule, not at all from stones. international acid. it is certainly useful and has all the useful properties that are attributed. but this is not amber, that is, it is a product, which can be produced either from amber, but most often it is a synthetic product. just amber. it is very difficult to isolate acid, it requires a multi-stage chemical process, and not just friction and historians. they say that although in ancient recipes. amber is often found by them. they even fumigated the premises during the epidemic. plague, there are serious doubts that he helped something, he was almost never used separately. it was always a kind of complex complex in one bed or in one pill or tincture. there is very when we say it's an amber pill. this trading is more the name of his role. this is, of course,
11:06 am
the creation of beauty, he is an undoubted symbol of kaliningrad, a driver of tourism development, and a social teacher. lyudmila vysotskaya came up with the idea of ​​using amber as an element of therapy for the blind and children with cerebral palsy. the stone is soft, bright and excellent material for crafts . e. we conclude that, after all, it is the processing of inventory that gives amber, e, it has already created an impetus the whole methodology of amber rehabilitation and brought it up. these create real miracles, which are real, unlike many things. what do they say and write about the ancient baltic resin? all week, as usual, i followed the news from the world of science and technology and made up the hot five of them. let's start with line number five. a beautiful way to make a

11:14 am
you are watching a miracle of technology. my name is sergey molodemov and now the news from the world of science and technology, which took fourth place in our weekly hit parade, is the rejection of salt in favor of the so -called salt substitutes. can save millions of lives. what is the conclusion of scientists from australia and china who conducted a large-scale study on 20,000 volunteers from 600 chinese villages. all of them were at risk for cardiovascular disease, had a past heart attack or were over 60 with high blood pressure in half of them replaced the salt with a powder containing only 75% sodium chloride and 25% potassium chloride. as a result, for almost 5 years of observation, a small but
11:15 am
persistent effect was indicated in the group with a healthier alternative, the risk of death was 39 per 1,000, and in the usual 45 difference. it seems to be not great, but on the scale of entire countries it will be. in a huge number of human lives it seems that everyone knows that electrical appliances and high humidity are a dangerous neighborhood, but there are fans of scrolling through social networks to watch videos lying in the bath with a laptop tablet or smartphone connected to the charger. but what can happen, i think, they are all isolated, others, on the contrary, are so afraid of a circuit that they try not to even wash themselves, with the washing machine turned on, where is the real danger, and where are the solid myths? accidents with chargers in the bathroom, alas, something
11:16 am
more than real. when we got out of the bath , the phone was lying on the floor, it was in charge, so that it would come connected. soon they were still trying to revive. well, as if it did nothing. here is a child. art critic's 12-year-old son dies anastasia sosnovskaya died just like that from an electrical injury during water procedures a few months ago, passing through the body stops the heart with its electrosensitive cells and it is not always possible for a physicist to restart the organ. vladimir reshetov clarifies that the potential threat lurks not in the phone itself, but only in its charger, which is in almost any phone. it has a maximum voltage of 4.2 volts, and we can safely lick your tongue. and nothing else can be done to really danger a cell phone. she's bound only with power supply. the
11:17 am
charger converts a large voltage from the outlet to a smaller one edible for gadgets. if condensation forms between the elements of the board at high humidity, we simulated this with a steam generator, a short circuit occurs, the current from the outlet directly via usb rushes through the wire to the phone that is in hand. oh, that this happened and happened in the work on charging is broken, we can say that at this moment a person will kill and kill , by the way, not voltage, but current strength the threshold value when a healthy adult can still pull his hand back without consequences is 30 mampers in our experiments. it was almost 150 and the problem is that electricity makes muscles convulsively contract. if you get electrocuted. you are even stronger. grab your phone even harder will beat. in general, charging your phone in the bathroom is a very bad idea. well, what about a hair dryer?
11:18 am
it's an even more common story. we conducted an experiment by dropping a bathtub with a working device and lightning, as it was not in the movie, but a mannequin from gelatin, imitating a person, received a serious electric shock. this was recorded by the devices, the experimental data showed 0.5 milliamps, which corresponds exactly to the fibrillation threshold, that is, in real conditions, that same cardiac arrest would occur. it is interesting that on the internet you can find videos in which the danger is exaggerated, explaining this by the fact that electricity flows along the path of least resistance. and in the skin it is much higher than in water. and while the body is in the liquid, the current will not flow there, vladimir
11:19 am
reshetov says that all this is true, but only with verified laboratory conditions did the experimenter secure himself on the video. he uses serviceable equipment, which does not have frayed wires and broken insulation, and what is important is that the bath has a non-metallic electric current circuit, it really closes to 22 v, it is inside the plastic case of the hair dryer and the current does not go out, the bath does not flow. she is plastic. she does not conduct from the directive. even when they spend in nature there, too, legs and everything else. that is, it works in the situation of a rubber mat under feet in life, the chain can be closed in a completely different way by the corresponding consequences. why not use a hair dryer in the bathroom at all now in england, for example, they played it safe and for a very long time simply forbade installing sockets closer than 3 m from a bath or shower. and since these rooms themselves are small, they are actually electrical appliances. it is absolutely impossible there,
11:20 am
our compatriot. dina is not in midzhanova. she says that when she moved to london 9 years ago, she was very surprised at this at the hotel. you won't find either to the bath. outlet rooms, that is, to cook here what to use a hairdryer or a curling iron is to do it in a room in russia, by the way, there are also restrictions. although not so strict, one of the guests allows the arrangement of electrics, no closer than 60 cm from the side of the bathroom or shower room, but this does not apply to sinks; competent repairmen try to take additional protection measures, use parts insulated from moisture and equip additional grounding, because it can be dangerous and stationary technology heaters and washing machines - any device that is even serviceable, it has a potential case that must go into the ground. if your case is not grounded through an outlet or in some other way. you run the risk of grounding all this interference into mother earth. learned yourself.
11:21 am
speaking in everyday language, then if the socket does not have these metal pins, but the plugs have these contacts, then there is a reason for the procon. with an electrician, the equipment is not grounded, and if during its operation on the surface, especially in case of malfunctions there will be a charge, he will only wait, as if to leave through a person who accidentally touches the body, if a person is with one foot, uh, in a wet, half-bathed, and with his hand, respectively, he touched the source, uh, power supply, then he can go along the arc. uh, arm leg and hit through the heart, respectively high and the likelihood that there will be a fatal outcome. some, being afraid of this, even try not to take a bath or shower with the washing machine running. but this is clearly excessive , it is really important to have grounding and not use in wet conditions those electrical appliances that are not

11:28 am
now the costume is coming to the customer funny cop wars today 19:30. and now the third line in the selection of the five most interesting scientific and technological news of the week us neuroscientists have created a straw to get rid of hiccups. it is indeed a problem for some people who are unable to stop the convulsive spasms of the diaphragm for a long time. this is how the mechanism of hiccups is formulated in medical language. the straw has a large
11:29 am
hole, on top and a small one on the bottom, which makes it suck liquid through it with increased effort. as shown by experiments on volunteers. it really effectively eliminates seizures by stimulating the vagus nerve. it is likely that the device with some similar principle of action can be built at home. you just need to remember that long or frequent hiccups can be a symptom of a serious illness and is definitely a reason to see a doctor. it's time for strict but fair tests. in the heading miracle goods as there will be two of them. today we will test innovative pebbles, smart replacement fertilizers and hypnotic flickering devices for falling asleep quickly. for those who suffer from insomnia, french inventors have come up with. this device costs almost 13,000 rubles. and promises
11:30 am
fast falling asleep due to the flickering of light projects a circle onto the ceiling that pulsates according to a given algorithm, when the eagle increases, you need to take a breath. and when the exhalation decreases in this way, the breath gradually slows down to six breaths. per minute. the heart also beats less. as a result, as advertising assures, the time to fall asleep will be halved . that's how much i can remember, very long time falling asleep. we gave the device to the gypsies for a week's test. true, sasha almost ruined the matter with his passion to record everything on the camera. light falls asleep with the help of his blue light thing. how about talking about success? don't hold your breath, so
11:31 am
you need to either breathe or talk further. sasha stopped filming and fell asleep almost immediately. light didn't do that. i breathed with the device, then turned on my side. and the whole dream has passed. i don't want to sleep again. sasha is sleeping, without any device he infuriates. she honestly tried to get used to and trained for several days, but tangible unfortunately, the result was not achieved. that is, breathing, my eyes begin to close themselves, sort of like, but when the eyes are already closed. i can’t go into deep sleep for a long time anyway after such news about how much the device costs, of course, caused a storm of emotions 13.000. of
11:32 am
course not, i thought maybe one and a half. maybe it's just something individual and we can find a use for the gadget in those who do not have serious problems. for example, will it help out on trips with a change in time zone to check this? i myself i took the device with me when i went on a family vacation to kamchatka. the time difference with moscow here is 9 hours day and night, practically changing places, of course, for many tourists from central russia at first. it's not easy here. many people fall asleep on excursions. on the first night of testing. my son, a lion, who likes to sleep on his side, began to resent the device, some garbage obviously interfered with him. she interferes with sleep. turn it off okay. all our attempts were unsuccessful and we used a proven tool sleep hormone melatonin tablets. they constantly
11:33 am
help me out on business trips to the most exotic and distant places. as a result, when people around were struggling with slumber. we were cheerful and cheerful. well, in general, kamchatka with its volcanoes, geysers, whales , killer whales was a success for everyone in the world, but this is not thanks to a dubious electronic warhead, but thanks to a healthy lifestyle and pharmacology. and most importantly, a positive attitude, and yet it may be that the device did not fit our body. we decided to carry out a real scientific test at the center of sleep medicine of moscow state university , our operator sergey bulando, who suffers from insomnia from time to time, will be the test subject. we have already tested one of the devices on it, but without success i can turn around from 4:00 to 5:00 in the morning , just with my eyes closed, a lot of sensors will help track changes in the patient's condition. we turn off the light in the next room.
11:34 am
somnologist. alexander kalinkin carefully monitors the readings of the video devices from the ward and the sounds also come to the doctor on his feet, that the person is not sleeping is present. yes, which is confirmed by the person himself, right? here, uh, unstable breathing. uh motor activity is noted, so all signs of lack of sleep. we specifically launched a long program on the gadget for 20 minutes. there are 8 more so that the subject has maximum time to relax and fall asleep and even wait another 20 minutes for a total of 40 during this time in the hallway. i managed to fall asleep. even our film crew, but not sergei himself, relaxation only from the fact that the bed feels relaxed i don’t know such and such a magical cocoon, because the waves do not exist. i didn’t have a device that should put me to
11:35 am
sleep by slowing down my breathing, and the technique recorded such changes, but somehow they didn’t affect my sleep, breathing, there is much less here. that is, inhale, exhale, inhale, exhale without a device, respectively. we see that the respiratory rate in a person is much, and more often about 15 respiratory movements per minute. but otherwise, we see that practically the same data as with and without the device if we compare both policies anagrams. we do not see elements that would tell us about the acceleration of falling asleep. the main disadvantage of the device is that it tries to act as a universal remedy for insomnia. and it's impossible to find it. the cause of the disease can be dozens and the treatment every time will be different. there are, of course, some universal tips for fresh air, an evening

11:43 am
that do not see people's experience and biologists from columbia and washington universities have shown that mosquitoes are guided not only by the carbon dioxide we exhale. what is known for a long time they are also attracted to dark objects, such as we we are for them like this, if we genetically disable two light-sensitive receptors, this instinct is lost in insects. there is still a lot of research ahead, but it is unlikely that sooner or later gene-edited mosquitoes will try to release nature so that they replace the usual ones with them. with little effort, more crops are advertised for this plant nutritional supplement. it is called an ionide substrate. and according to advertising, it was invented back in soviet times, when they planned missions to mars and venus developer and co-founder of the manufacturing company belarusian academician. vladimir
11:44 am
soldierov explains the principle of action when a plant feels a lack of nutrients. it releases certain particles into the soil. they penetrate inside the celite of a porous mineral, which was saturated during production, with the food necessary for plants, an ion exchange occurs between the substrate and the soil from which the plants come from. in the end, you can take everything you need. the main thing, as the advertisement tells the gardener. no need to calculate the amount of additive pour. as much as you want in any soil , an overdose is impossible to pay for a portion of 700 g of a promising product, you will have to pay a lot of 790 rubles. does it make sense to spend such money on fertilizers although sellers avoid this word, an experienced gardener irina korsakova will check at our request irina studied the jar with the additive and her trained eye immediately caught on to some formulations. here, for me, some completely incomprehensible
11:45 am
abracadabra is not mineral. good fertilizer, but at the same time contains nitrogen, phosphorus and potassium with it. we will definitely figure it out and , most importantly, we will conduct full-scale tests. irina will grow cucumbers with a nutrient substrate and, for comparison, without it in a greenhouse and in a garden, and in our studio, five will act as a test group. we leave one pot of petunias without any fertilizer at all. this will be a control sample in another container, mix the earth and the applicant for the sticker. we will add sand to its miracle. yes, yes, the producers claim that with their feeding , the plants will grow on any soil for one more flower. we bought a popular and long-sold substrate from a german manufacturer. it does n't even need soil. only a special pot with automatic watering cost 2,000 rubles. well, the fifth subject will eat a supplement that
11:46 am
an experienced light guide will pick up. olga voronova in her blog, she actually admires the anite substrate, but on her site she is not averse to using something cheaper cat litter thing, but uh, my additive turns out to be a few bushes compared to ready-made forms, because i can’t make hell from a dream, i do not own laboratory technologies. i have at all there is no laboratory here. olga takes my beds here, a clumping filler that does not lose its shape when in contact with water, mixing it with soil and adding fertilizer, for example, a mineral plant without cat filler would immediately eat all the nutrients, and then there would be a deficiency, but there should be a slow allocation is worth such top dressing. as a result, it will be less than 100 rubles, let's leave the petunias to grow. in the meantime, let's return to our summer resident irina korsakova after a month and a half. her garden is already full of cucumbers. it's time to shoot

harvest. despite the fact that two plants were missing. in this row, with the addition, the crop, uh, was 15 greens, and the crop without the addition was 16, that is, in terms of quantity, this is a comparable number, but the cucumbers that grew in the soil, without any fertilizer, turned out to be larger in the greenhouse, where there was added anite substrate, one seed did not germinate and the yield was 14 fruits, against 19, which irina removed from the plot without additive. i can’t understand the enthusiasm of many bloggers who say that i can’t live without her, but, frankly, experience my personal experience with these cucumbers shows that the supplement is, well, to put it mildly, not very effective. however, a laboratory test showed that the additive is still not a dummy, the amount of nitrogen, phosphorus and potassium corresponds to those stated on the packaging, while the

manufacturer. avoids calling his product a mineral fertilizer. apparently just to make your life easier to avoid unnecessary bureaucracy and check mineral fertilizers - this is an agrochemical that is subject to registration. in this case, on packaging. we do not see this information, which is why the manufacturer called it a substrate. and we also managed to find out that the co-founder of the manufacturing company, academician vladimir soldov, was really developing a similar substrate for space programs. now scientists have created something similar for an orbital greenhouse, but such fibrous fertilizers will not scatter in zero gravity and experts. by the way, they doubt that in more favorable earthly conditions, it generally makes sense to use such additions of a meter. eh, good black. yeah you can get up to the car more than with any and they do not confirm this by soil. this is

the result of our experiment with petunias, according to agricultural technologists vladimir lukanin, the flowers felt great in a pot with ordinary soil, without any additives in the soil, the substrate is also normal, but cat litter with fertilizer is a little worse, the worst situation is in the most artificial versions of german granules. and when you try to replace the soil with sand and substrates, the roots are practically invisible. because of what it most likely means that she wants to hurry end its life cycle. this result did not surprise the expert. he has already tested this supplement on the tomatoes of my experiment. unfortunately , it was not possible to bring the plant to the end in good quality, and the classic right to mineral fertilizer proved to be the best. our conclusion from the ionide substrate is not worth the wow result. you can

save money by buying good soil or just mineral fertilizer, and if the plant has enough light and the right amount of moisture, then the advertised expensive additive will not it won't take a miracle. it remains for me to reveal to you the main secret. what discovery or invention did i decide to put on the first line in this week's top 5 attention to the screen? the world is getting closer to the fact that chargers for phones and many other gadgets will simply not be needed. more precisely, they will become wireless and inconspicuous. a group of scientists from japan and the usa showed a whole room, in the walls, which emitters are laid. moreover, such a technology was used, which made it possible not to exceed the levels permissible for a person at the same time. charge or power several devices wirelessly at once.
