Bursts FRB dreaded astronomers for nearly 20 years. Unfortunately, today failed to explain their origin. They last a millisecond, but bring with them the energy that the sun generates throughout the month.

For years, under investigation over an attempt to explain the source and nature of these mysterious phenomena, but the more we know about them, the farther we are from knowing the whole truth. At this time it is believed that it may be signals generated by black holes, pulsars implosions, the collision of neutron stars, or magnetars, and even the effect of travel in space aliens or one of their methods to establish contact with other civilizations.

Recently, scientists from the University of California at Berkeley, decided to use the technology of artificial intelligence to search FRB flashes on the basis of those registered so far. During the experiment, lasting five hours, we were able to identify as many as 72 new high-speed radio flashes from one source away from Earth three billion years of light, increasing their number up to 300. Despite the knowledge that the source is 3 billion light years from Earth, still we do not know its exact location, and the more we can not identify what the object generates these flashes.

It is worth noting that not all the flashes come from the same place and are so energetic. In April this year detected 30 new FRB flashes that lasted just 2 milliseconds. But it was enough, he would have been immediately recognized by astronomers as unique, as are characterized by much lower frequency of recorded so far.

Most of them were in the 580 MHz and dozens of us have known the 700-900 Mhz. Recent FRB flashes were recorded by a brand new radio telescope CHIME (Canadian Hydrogen Intensity Mapping Experiment) located in Canada. Although the detection of more and more FRB, they are still a mystery to us. Soon, however, this may change, and this is thanks to the world’s largest radio telescope.

Chinese FAST so far specialized in detecting pulsars, which is highly zmagnetyzowanych, rotating neutron stars that emit a beam of electromagnetic radiation. Now, astronomers want to use it to discover new FRB flashes. FAST in the past few weeks, several dozens of detected signals coming from the same place, and in a very short time. First detected flare was defined as the FRB 121,102.

It seems that the Chinese giant called FAST is designed for this type of projects. Astronomers intend to so with his help detect hundreds or even thousands of new FRB. It is estimated that every second of the Earth there is a lot of such signals, but we are not able to detect them. Now he has to change for the better. The entire project will last nearly a decade, but it has resulted in a final solution of one of the greatest astronomical mysteries of mankind best tech advices. Fingers crossed for the success of the whole project.

The Chancellery of the President of the Republic of Poland has just announced that on September 6, 2019, President Andrzej Duda signed the Act on the development of telecommunications services and networks, it will enter into force 30 days after being announced.

The Act on the development of telecommunications networks and services is also often referred to as the mega-act, because it introduces changes to as many as 14 existing ones. As we learn from its justification, the goal is to remove existing administrative and legal barriers that constitute an obstacle to the construction of broadband networks. This reduction of administrative, legal, procedural and financial burdens is to be a condition for Poland to achieve the objectives set out in the National Broadband Plan and commitments to provide access to modern telecommunications services resulting from membership of the European Union.

So what changes should you expect? Expanded among others definition of telecommunications infrastructure with a slight impact on the above-ground cable line, the possibility of local governments financing investment costs, a Broadband Fund was created as an instrument to support the development of broadband Internet access services from domestic funds, and a chapter was added that contains regulations regarding the creation of an Information System for Radiation Generating Installations Electromagnetic, which will be a public, free database containing information about the electromagnetic field in the environment technologi.

Rates for occupying the road lane were also reduced in relation to telecommunication infrastructure facilities and equipment, and the possibility for the local government unit to conclude the so-called investment agreement, under which, in exchange for the investor’s implementation of an investment meeting the community’s collective needs, the rate stipulated in the Act can be further reduced (such investments desired by the local government may not only be broadband networks, but also electricity, water and gas networks). Moreover, access to forest areas for placing telecommunications infrastructure in these areas has been greatly facilitated.

The modifications to the environmental protection law, where the regulation on permissible levels of electromagnetic fields in the environment has changed, cannot be omitted. In addition, from the entry into force of the Act, measurements of electromagnetic fields around installations or devices will be carried out immediately before commissioning of the installation or device, and the manager or owner of the property on which there has been a change in the existing state of development and development of the property, resulting in changes in the occurrence of places available for people around the installation or device, will be able to apply in writing for new measurements.

The Act also increases the possibilities of building infrastructure in areas where until now there was a ban or significant restrictions in this area, such as: health resorts, national parks, nature reserves (e.g. by lifting the bans and restrictions on locating non-linear telecommunications infrastructure in spa areas and enabling – in strictly defined cases and after meeting certain requirements – the construction of non-linear telecommunications infrastructure installations in the area of ​​national parks or nature reserves).

Of course, the word air conditioning is a kind of abuse here, but as scientists have just discovered, this dinosaur was able to regulate its body temperature in a very interesting way.

Thermal photos of alligators taken by a team of scientists led by Casey Holliday from the University of Missouri School of Medicine suggest that Tyrannosaurus rex may have had blood vessels in the skull that helped this giant predator regulate body temperature, in other words it had biological conditioning in it. So it seems that although we have been trying to unravel the mysteries of this iconic dinosaur, which is constantly arousing the imagination of scientists and children around the world, it still hides many secrets.

T. rex lived in the Cretaceous period, some 68-66 million years ago and could boast of really impressive dimensions – it was up to 12.3 meters long and weighed up to 14 tons, and its first skeleton was discovered in 1900. Since then, staffs of researchers have been studying it piece by piece, trying to learn as much as possible about its anatomy, physiology and habits. Unfortunately, despite this more than 100 years of experience in this field, the brief still has not been able to solve all puzzles, e.g. related to his body temperature.

Until the sixties of the last century, scientists claimed that, as befits a reptile, T. rex was cold-blooded, but later there was evidence to suggest otherwise, i.e. both he and the other dinosaurs were probably warm-blooded. How was it actually? The first, the second, or maybe something completely in between? To this day it is difficult to say, but as recent experiments show, it certainly had a mechanism that made sure that the predator did not overheat or did not freeze too much.

Researchers from the University of Missouri School of Medicine believe that these are cranial blood vessels located in two large holes in the head of T. rexa, which acted as an internal thermostat – so far scientific circles have said that these holes are places for muscles Jaws: It’s very strange for muscles to come out of the jaw, make a 90-degree turn, and continue to the skull vault web alpha directory. Either way, we have a lot of convincing evidence for the theory of blood vessels in this place, based on our work with alligators and other reptiles, “says Casey Holliday.

To learn more about these holes, the team used thermal photos taken by alligators in St. Augustine Alligator Farm Zoological Park, Florida. – Alligator body temperature depends on the environment. However, we noticed that when it was getting cold and the reptiles wanted to warm up, the thermal image showed large hot spots in said skull holes, indicating a rise in temperature. When it got warmer, the points became dark, as if someone had turned them off to keep the temperature low. This corresponds well with earlier evidence suggesting that alligators have internal thermostats.

And since there are many similarities between the skull of the alligator and T. rex, researchers believe that the dinosaur had the same mechanism. What is interesting, however, still does not answer the question whether the tyrannosaur was stable or cold-blooded, because in nature we observe similar solutions not only in reptiles, but also mammals. For example, dogs also have cranial blood vessels that protect their brains from overheating, which would be very useful for a warm-blooded predator, because it might suggest that it would be able to chase its prey until the same one died from overheating. In short, we still have many questions, but there is no guarantee that we will ever get answers to them.

Most of us without our smartphone in sight feel practically like without a hand, but at the same time it is difficult for us to admit that we have a problem with addiction to new technologies.

However, if we notice a problem and want to repair our relationship with a smartphone and other mobile devices a bit, then Light Phone II will help us. Of course, no one expects us to completely cut off contact with the world, but limiting communications to the necessary minimum may prove beneficial in many cases. So what is Light Phone II? All in all a basic smartphone, but designed with the aim of reaching for it as rarely as possible.

All to cut off the flood of overwhelming amounts of information from social media that put pressure on us and force us to spend long hours with eyes gazing at the screen – as recent studies show, we often break our sleep just to look at the notifications! And here the minimalist Light Phone phones come into action, which only offer basic communication options, i.e. conversations and text messages, and several other functions.

With the help of Light Phone II, we can call and write messages, we have a calendar, calculator, alarm, notebook and the option to listen to music (3.5 mm jack) and as the originators of the project say: – Light Phone II will never have social media , channels, ads, news and emails. As for the specification, we are talking primarily about a small 2.84-inch E Ink touch screen, battery providing up to 13 days of standby time, a microUSB port for charging and Bluetooth connectivity.

In short, components from the previous era that have no chance in the clash even with the most budget smartphones recently hit the market, but that was the concept of the manufacturer darknethub. And everything would be fine if it wasn’t for the prohibitive price of as much as $ 350 – of course we all understand the idea of ​​the project, but if you can have a decent smartphone for the same amount of money, it will be difficult to convince anyone to buy. Or maybe we are wrong and the manufacturer will initiate a new trend with his solution? We’ll find out in October, because then the device will officially hit the market.

Someone had to make money from the trade war between the United States and China, and the latest reports suggest that it will be Foxconn, who wants to use India for this purpose, which is growing to the next power.

Foxconn believes that this will be the best place to assemble all future iPhones, and the local government confirms the concern in this belief, believing that his country will win something for themselves and eventually become a global electronics production center 1337 directory. Will this work out? It is hard to say, but given that Apple must be ready for a 10-15% tariff imposed by the Donald Trump administration on goods imported from China, it will certainly be looking for a cheaper alternative, which may be India.

Until now, the American giant was looking around in Brazil and Vietnam (following the example of Google, which wants to assemble its Pixel smartphones in the latter country), but everything indicates that India may be a better option. Foxconn has already built two factories there and is waiting for building permits for another two to gradually increase its share in the production of new iPhones. And why India? According to Bloomberg, the matter is simple, there is a lot of very cheap labor there, and we are talking about a level comparable with China.

The Indian government had previously been rather reluctant to cooperate with major manufacturers, but now it has apparently changed its mind and intends to make a solid profit from the war between the US and China. What’s more, the necessary actions have already been taken to adapt local regulations to new conditions and encourage manufacturers to build factories – but it is worth remembering that a lot has to happen on the spot, because even now road and rail infrastructure is not ready for an increased number of producers and implementation of huge supply chains. Either way, the government’s plan is to increase India’s manufacturing value from $ 25 billion to $ 400 billion by 2024.

According to Anshul Gupta, a researcher from Gartner India: – Everything is starting to shape. India can increase its production capacity and help the world become independent of China. It took China 30 years to reach its current position, but now many large concerns, such as Amazon, Apple, Google or Dell have expressed interest in India, so it can go much faster.

Unfortunately, there are also less pleasant sides of the whole process, namely the current Foxconn factories employ mainly women who get $ 4 a day for assembling such equipment as iPhone X, XS or alternatives from Xiaomi. For many women, this is an opportunity to take up their first job away from home, for which they are paid and a chance to live above the poverty line, but it can not be hidden that $ 130 a month is not very impressive, and Foxconn has a lot of employment controversy minors and poor working conditions, so it would be good if someone had their finger on the pulse.

Some time ago, we learned that the Federal Trade Commission (FTC) has initiated an investigation against the media giant regarding violations of the Children’s Online Privacy Protection Act. And now the consequences are coming.

We remind you that this is an act that entered into force on April 1, 2000, and its main purpose is to protect the privacy and collection of personal data of children under the age of thirteen who are users of websites directly addressed to them or other services, if they have they know that they collect the personal data of children under the age of thirteen. It cannot be hidden that YouTube must have known that some of its users are children who meet these criteria, so now it must bear the relevant consequences.

The first is the penalty imposed by the commission, the exact amount of which is not yet known, but will probably amount to USD 150-200 million. In addition, the service must make some changes to avoid similar situations in the future, but we will probably know more details in the next week, when the FTC will present its official position on the matter. It is worth emphasizing, however, that most of the committee’s requirements will certainly be met by the new YouTube Kids service, which has just started, but on the other hand, this one before the debut aroused the opposition of some creators best web guides.

It has appropriate filters and records in the privacy policy to protect young recipients (and creators) and cut them off from violent and inappropriate content, including advertisements targeted at them. Hence the Google idea of ​​transferring content for minors to YouTube Kids, which the creators are afraid of, because it may mean smaller ranges and profits. And according to recent research from the Pew Research Center, every video with a child under the age of 13 collects nearly 3 times more views than material on a different topic, despite the fact that YouTube requires its users to be more than 13 years old:

– This small subcategory of movies that were created for children or appeared in children, especially up to 13 years of age, was more popular in terms of the number of page views than any other topic examined by us in this report – we read in the report. No wonder that the authors of these channels are hostile, especially since the new regulations do not guarantee that children will not find a workaround to use the site on the existing basis. On the other hand, we have organizations dealing with privacy on the web, which claim that the FTC has treated the next giant too gently, while legalizing its new empire.

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 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.

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.
