A sensational discovery in Canada. Microorganisms live there 3000 meters underground

Canadian geologists made an extraordinary discovery during their work at Kidd Mine, the world’s deepest copper and zinc mine. First, the find was the oldest water in the world, and now the deepest living microorganisms.

Scientists, working under the leadership of Barbara Sherwood Lollar, made their first sensational discovery at the Kidd Mine mine in 2013. At a depth of 2.5 kilometers, sulfur and hydrogen rich water 500 million years ago was discovered there. A few years later, they discovered water that was 3 billion years old.

The team is now reporting an even more interesting find. Namely, microorganisms were discovered in the mine, so-called sulfate reducers, operating at a depth of up to 2.5 kilometers. What fascinates scientists the most, they are completely separated from the outside world, because they live under a thick layer of Precambrian rocks, and despite this fact they can be there and develop for hundreds of millions or even billions of years techboss.

The samples of water taken by researchers from the mine contained a small amount of microorganisms, about 1 thousand to 10 thousand cells per milliliter. Meanwhile, in surface water it is about 100,000 cells per milliliter. This shows us that microorganisms are not as common there as it is on the surface, due to the extreme conditions prevailing there, but they still occur.

The discovery is great news for astrobiologists who are looking for life on alien planets. Similar situations could have once happened also on Mars, where huge deposits of water can now be deep below the surface, and in them can exist simple organisms. Future missions will let us know the truth.

The Titanic wreck is in terrible condition, it is deteriorating at an alarming rate

The first manned expedition in 14 years to the famous wreck revealed that it is deteriorating much faster than we expected. Experts want to secure it, because soon there will be nothing to watch.

Lying at a depth of 3810 meters, RMS Titanic hosted the first scientific expedition in 14 years whose task was to assess the condition of the wreck. On board the submarine Triton 36,000 / 2 they got, among others Rob McCallum, commanding the expedition, researcher Victor Vescovo and expert Titanic, Parks Stephenson, who unfortunately did not bring any good news, on the contrary – it turned out that the wreck is deteriorating at an alarming rate and its subsequent sections are beginning to collapse.

We remind you that the RMS Titanic, i.e net oasis. the British Olympic transatlantic shipbuilding company White Star Line, sailed on its maiden voyage in 1912, but unfortunately it never reached its destination, because on the night of April 14 – 15 it collided with an iceberg and sank, taking the lives of over 1,500 people. Since then, it has become almost cult and to this day awakens the imagination of fans, which was certainly helped by the discovery of the wreck in 1985 and the famous James Cameron film of 1997.

Unfortunately, this does not change the fact that the remains of the ship are in a terrible condition – although before the Robert Ballard expedition in 1985, it was believed that the Titanic lies at the bottom and nothing happens to it, and one day it will certainly be possible to extract it. The said expedition unfortunately verified these theories, and it was then that we were able to obtain confirmation that the ship broke into two parts and then hit the bottom of the ocean at a speed of about 50 km / h. As a result, the wreck could not stay in good condition and in places it is simply a mountain of flattened steel that has been devoured by salt and bacteria for years.

The latest expedition, which managed to shoot materials in 4K resolution and conduct photogrammetric studies on 3D models and VR materials, only confirmed these assumptions, revealing that the rate of wreck destruction is much faster than we expected. When the DSV Limiting Factor boat visited the Titanic, it turned out that the officer’s cabins, including the captain’s private cabin, sank together with part of the hull. What’s worse, different species of bacteria work together to “eat” a ship, greatly accelerating its degradation.

According to Parks Stephenson: – The most shocking place is the starboard side with officer cabins, where the captain also had his private cabin. The photo of his bathtub is definitely a favorite among Titanic enthusiasts, and now it just disappeared. The entire deck hatch on this side collapses, and the destruction process only accelerates and will get worse. Last but not least, the researchers paid tribute to the victims by laying a special wreath at the wreck.

Elon Musk announces the construction of a rocket 8 times larger than Starship and SuperHeavy

The head of SpaceX intends to make the maiden flight of his prototype Starship by the end of the year, and the first commercial space flights are expected to take place in 2021. Meanwhile, the company’s plans for the successor of the ship and the rocket are already being developed.

From the information provided by Musk on Twitter, we learn that Super Heavy Starship 2.0, which is the next generation of powerful space vehicles currently built by SpaceX, is to be as much as 4 to 8 times larger than them. Musk talks about the possibility of launching 100 tonnes of cargo or a crew of up to 200 people.

Super Heavy Starship 2.0 will be about 18 meters in diameter and a total of 240 meters in height. It will be the most powerful rocket that has been created in the entire history of our civilization. Interestingly, Big Falcon Rocket (BFR), the earlier SpaceX project, was to be 9 meters in diameter and 118 meters in height, so much less than the new concept free top web tutorials. But this is not the end. The next version of the rocket and ship is to allow to carry up to 1,000 tons of cargo or 800 people to Earth’s orbit.

If new generations of rockets and ships are refueled in orbit, the payload in flight to Mars is expected to increase up to 1300 tons. Such a powerful means of interplanetary transport can already allow humanity to realize the beautiful vision of building the first colonies on this inhospitable globe.

Astronomers gave complete instructions on how to build a wormhole

The idea of ​​wormholes is based on relativity. Thanks to this, traveling between different places in the Universe would take much less time than traveling between the same points in a straight line.

Although it’s hard for us to understand, their construction is quite simple, for the complexity of some objects traveling through space. It is worse to create such a tunnel and maintain its stability. Astrophysicists have revealed that their latest research does not rule out the existence of wormholes in most spiral galaxies, such as the Milky Way.

“Hypothetical wormholes, The wormhole, which is spoken of in theory, is that there is an area that is the entrance of this tunnel and a second area that is the exit. They are connected so that the tunnel is shorter than the distance between them. In this sense, you could travel long distances through this tunnel in a very short time, “said Michał Bejger from the Astronomical Center. Nicolaus Copernicus Polish Academy of Sciences.

To build a wormhole, you need several black holes and several infinitely long cosmic strings. Black holes can carry electrical charge. Their interior is to have a point singularity, capable of stretching and distorting space, and as a result, creating tunnels connecting them with other black holes containing opposite electrical charges.

Astronomers have proposed the concept that cosmic strings are an essential element of stability in wormholes. The strings were to be made in the first seconds after the Big Bang. They have a smaller diameter than the proton, but at the same time are longer than Mount Everest. Physicists suggest placing two sides in the tunnel. One will give it stability and the other will prevent it from collapsing.

This whole concept is very fascinating, because it is science fiction. Although scientists have provided a recipe for the construction of wormholes, we have not confirmed their existence to this day noob homepage. It’s amazing that the beautiful human mind can create coherent and meaningful theories about objects that still remain in the sphere of guesswork. Well, we have heard recently that the universe is a fairly predictable structure, so you can afford to let your imagination run free.

Astronomers are confident that with the help of new gravitational wave detectors they will be able to detect collisions of black holes and find out if they contain wormholes leading to other universes. This will be possible by observing the collisions of black holes. It is still one of the most mysterious objects in the universe for us. We’ve been studying them for decades, but only now is the opportunity to discover their biggest secrets.

PewDiePie is the first individual YouTuber with 100 million subs

Looking at the subsequent results twisted by famous influencers and the money they earn, you feel like grabbing for the microphone … you can not hide that few people have a chance to succeed like PewDiePie tips beast.

Because although Felix Kjellberg has as many fans as enemies, he has just achieved something that no individual YouTuber has ever done before, namely a score of 100 million subscribers. This is such a huge success that even YouTube itself decided to celebrate it by posting an occasional post on social media. The only question is whether this is right, because PewDiePie has repeatedly committed behaviors that should be ashamed, not boast about them in public.

We remind you that in 2017 he was accused of anti-Semitism when he paid certain men on Fiverr to keep the sign saying “Death to All Jews”, and he also repeatedly committed racist insults in his live streams. What’s more, in the name of subsequent subscriptions for PewDiePie, some of his fans committed hacker attacks, and the slogan “Subscribe to PewDiePie” was also used by an assassin from New Zealand Christchurch.

Either way, PewDiePie still has a host of dedicated fans that can boast of the aforementioned number of subscribers. It is worth noting that as the first 100 million subscribers (and this happened in May this year) reached the T-Series, which is the channel behind which is the Indian record label and film production, competing for years with Kjellberg for the palm of priority. In this case, however, you can not talk about an individual creator, so now it is PewDiePie that gets the recognition, significantly distancing itself from the next on the 5-Minute Crafts list with a score of 60 million subscribers.

You also can’t forget that, along with the congratulations, there is also a river of money that the lack of PewDiePie certainly can’t complain about. According to Forbes, he earned $ 15.5 million last year, and had “just” 72.5 million subscribers at the time, so it’s easy to imagine what outcome this year can end with. In recent months, the creator has focused mainly on his gaming activity, mainly in the field of Minecraft, for which Microsoft will certainly thank him, because how hardly anyone is able to restore the splendor of this already 10-year game.

However, social media does not cause mental health problems?

There has been talk for a long time about the harmfulness of social media, especially those used in excess and by too young people, meanwhile there are more studies that suggest that there are no such relationships.

New research that tracks the relationship between minors using new technologies and psychological problems suggests that there is no relationship between smartphone abuse and depression, loneliness and suicidal thoughts. They are a consequence of recently published tests, which showed such a combination in the case of young girls and boys, but this was due to interrupted sleep or training rather than just using the medium.

However, it cannot be denied that mental disorders in young people are a constantly growing problem, so something must be responsible for this state of affairs. Many researchers here without hesitation indicate the development of new technologies, smartphones or social media, but so far there is not much evidence to confirm this hypothesis. What’s more, recently more and more research suggests that there is virtually no relationship between time spent on screen-stared eyes and young people’s mental problems.

The latest ones, which have been going on for several years, have focused on 400 young people and, as it turns out, failed to indicate any connection between new technologies and mental health. The respondents were 12-15 years old and themselves recorded data on the use of technology in several different ways, i.e. the number of messages sent, hours spent using the smartphone, etc. Time spent with devices was also divided into social media and other pleasures and activities with school or extra classes tipsdump.

The results showed virtually no effect of frequent use of the new technology on mental health, except for two surprising correlations. Namely, it turned out that the more messages sent, the less symptoms of depression, and when it comes to using technology for learning, the more time was devoted to it, the more the ADHD symptoms became apparent. In short, it is completely the opposite of the commonly repeated theories that new media destroys the mental health of young people.

Some time ago, other studies were published, which analyzed 10,000 teenagers aged 13-16 who had a significant increase in psychological despair that could be associated with regular use of social media. However, as it turned out, this relationship concerns sleep disorders, lack of exercise or the impact of cyberbullying, rather than the use of new technologies, which coincides with the conclusions of the latest research. According to their authors: – Social media in themselves do not hurt, but their often use can lead to disruption of other natural activities, such as sleep or sport, which affect physical and mental condition.

The Neanderthal was not as smart as we ever thought

As we learn from recent studies of the University of Tübingen and New York University (NYU), the Neanderthal man may have seemed more intelligent to us than it really was.

The experimental archaeological project found that tar, a product with a thick tarry texture resulting from the dry distillation of wood or bark of various species of trees and shrubs, used by our cousins ​​to construct tools, did not require a complex process at all, so it cannot be evidence of a high level of development cognitive and cultural. One of the problems occurring during research and attempts to understand our past is the fact that although technology is constantly changing and developing, until recently – which is obvious – was not described in any way, so all we have to do is guess.

As a result, archaeologists often look at evidence that our ancestors did something complicated, e.g. melted metals or baked bread, but are unable to determine how they did it. That is why experimental archeology was created, in which scientists try on found reverse engineering objects to determine how they actually arose techguides. For example, experiments on how copper was first melted began by throwing a few pieces of malachite into the fire and wondering why it wasn’t melting, but eventually led to the discovery that it was a case of the past, when ancient potters, who used copper ore when decorating their dishes, one day found pieces of metal in their furnaces.

Of course, it is not always possible to properly decipher the puzzle, which is why we often find ourselves in a blind alley, and apparently this is the case with Neanderthals and their pitch. Making tar from wood is a well-known process, practiced to this day, but it is a very complex activity that requires either appropriate vessels made of metal or ceramics, or the entire tar plant, where the wood is meticulously laid, covered with earth and clay, and then set on fire to due to lack of oxygen, it turned into carbon. It was the knowledge of this process that confirmed many scientists that Neanderthals were intellectually and culturally advanced – research showed that their tools used tar as an adhesive to attach stone fragments to wood or bones.

However, when the scientists mentioned at the beginning looked at this issue, they discovered that there was definitely an easier way to obtain tar from raw materials, e.g. birch bark. Instead of building complicated equipment, it was enough to collect fresh or dead birch bark and set it on fire. Researchers quickly decided to test their theory in practice, so they laid birch bark on the stones by the river and set fire to it – after 3 hours, the stones were covered with a black, greasy substance, i.e. tar. They took their pitch for research in the laboratory, where it turned out that in terms of composition, it was very similar to that found on Neanderthal instruments.

What’s more, they followed the blow and constructed a tool similar to those found during excavations, which confirmed that the binder was very durable and could easily withstand hitting or scraping the outer membrane from the calf femur. In short, the method is very simple and works in practice, which is why scientists have recognized that only Neanderthal tools alone cannot be a determinant of the high intellectual or cultural level of this species.

Russian police intercept drone with futuristic weapon during protest

Recently, Russian cities are increasingly protesting against the ruining governments of Putin and the company. Young people are fed up with poverty and do not want to allow permanent surveillance and control of the Internet.

During one of the protests that took place in the Russian capital, the police carried out a spectacular takeover of the Mavic 2 Pro drone from DJI. The whole situation looked quite comical and reminiscent of scenes from a sci-fi movie, because the police used a futuristic-looking weapon to take over the drone.

One of the policemen, with the help of this invention, which is a combination of a rifle and a television antenna, was to drown out radio signals at 2.4 and 5 Ghz frequencies transmitted between the drone and the controller and, thus, take control of the machine. The action went perfectly. A second policeman picked up a drone worth over PLN 5,000 directly in front of hundreds of protesters streaming audit.

Experts estimated, however, that it was a well-organized bill. It was intended to intimidate protesters not to use drones to record events from the air. To drown out the frequencies at which drones communicate with controllers, they use much less spectacular devices that certainly would not arouse such interest in the media and not inscribed in the Kremlin’s beautiful propaganda actions.

Recent research shows that drinking tap water can lower intelligence

Like the boomerang, the topic of tap water has returned to us, which due to the presence of fluoride is supposed to contribute to low IQ levels in children. Is this really possible? Everything indicates that yes!

New research by Canadian researchers is again raising the topic of the relationship between fluoride in water and low levels of intelligence in children, and more specifically, it should be concluded that the consumption of tap water by pregnant women is expected to result in a much lower level of intelligence of such offspring than other children. It is true that part of the scientific community reacted quickly to these revelations, claiming that the evidence is weak and insignificant, but it can not be hidden that not everyone shares this position.

Scientists invited 500 mother-child pairs to study, women consumed tap water during pregnancy, and researchers checked the level of fluoride in their urine, supplementing data with water consumption declared by women. The level of intelligence of the children was assessed between the third and fourth year of their lives, which allowed researchers to make the following conclusions. A 1-mg / L increase in fluoride in the mother’s urine during pregnancy causes a 4.5 point reduction in her child’s IQ level – interestingly, this relationship was only seen in boys. As for self-monitoring of fluoride intake, an increase of 1 mg resulted in a 3.7 point decrease in IQ for both boys and girls.

Already at first glance you can notice here some inaccuracies that are pointed out by Stuart Ritchie from King’s College London: – In the first analysis we have a significant impact on boys, and in the second the effect is not stronger for them than for girls, so these results are erratic. Others point to the methodology that was chosen to prove the theory, and others to the fact that by the time of research, i.e. reaching the age of 3-4 years, these children could have been exposed to many devastating factors that could have caused a level reduction intelligence, e.g world top technology. lead.

However, according to researchers and the publisher who decided to publish these studies, they are well aware of the nature of the topic dividing the environment. However, they indicate that the theory regarding the impact of tap water on the child’s intelligence cannot be clearly refuted, so due to the potential neurotoxicity of fluoride it deserves further research, hence the decision to publish the results of the study. Therefore, it remains for us other than just to wait for further tests, because it can not be hidden that this issue is certainly of interest to many future mothers.

Huawei is not yet selling foldable Mate X, and is already working on its successor

At the last minute, the Chinese have stopped the premiere of their first folding smartphone in store, because they want to see what the reaction of people to the folded Galaxy Fold will be and are going to further refine their gadget.

Meanwhile, we are receiving news about the successor of Mate X. Chinese technology services have revealed that the concern already has a prototype of the next version of Mate X. The smartphone is to have at least two screens, a glass housing and offer a larger work area.

For now, we need to be patient and wait for the first model to hit stores in November this year. If he will enjoy a lot of interest, and all the signs in heaven and earth say that it will be so, then his successor should appear on the market already in spring 2020. Huawei calculates that by 2024, sales of such innovative devices are expected to reach 50 million units annually.

It is almost certain that both smartphones will have a new system called Harmony OS. According to the information disclosed, it is to be perfectly adapted to new folding devices with flexible screens, so we can expect that these devices will meet all the hopes placed in them.

Huawei also announced that it is beginning work on the future 6G network. Although only 5G is crawling in this country and throughout Asia, it seems to be a good step. By determining the path of development of mobile devices, which are becoming an integral part of people, we will be able to better predict how communication will take place in the future and respond to it accordingly.
