A device was created that perfectly detects the coming outbreaks of aggression

And of course we are not talking about a new device for ordinary nerves, but a medical gadget that can help people dealing with autism – thanks to this they will gain some time to silence their pupils.

Medical technology has been doing great lately and we are literally hearing about some impressive breakthroughs and innovations that make diagnosis and treatment run much more efficiently. Her prediction section is also doing quite well, which is obviously helped by artificial intelligence, which can diagnose heart disease, vision or psychological disorders in advance.

Now scientists from Northeastern University have presented a new solution for people struggling with autism, namely a special device to wear on the wrist. It looks like a smart watch, but in fact can predict the outbreak of aggression in sick people, giving them or their carers 60 seconds to control the situation.

Of course, we all realize that this is very little, but sometimes a minute is enough to control the situation or take such a person to a quieter place, cutting them off from factors that can cause their discomfort and irritability, especially since in some forms of autism other contact with the patient is strongly limited or even impossible.

And how does it work? The device monitors certain features, such as pulse, hand movements, sweat production, and more, so when they change, it can predict the oncoming attack. Until now, the gadget was tested on 20 autistic children who carried it for 87 hours and it turned out that the equipment can boast 84% efficiency best web guides. Researchers hope to improve it, but the first stage of their work is to expand the test group to 240 people, not only children but also adults who have a history of outbreaks of aggression. And if everything goes according to plan, we should not wait too long for the commercialization of this idea.

Ancient tools prove the much earlier presence of homo sapiens in Eurasia

In recent months, a lot of new research has seen the light of day, which forces us to verify knowledge about the origins of our species. The latest ones concern the wanderings of the first people in Europe.

It cannot be hidden that the history of our species is full of holes and understatements, but fortunately we fill the next ones in small steps worldtoptech. Until now, we thought, for example, that the history of modern man began about 300,000 years ago and about 120,000 years ago went beyond Africa, while in Greece we found skulls of homo sapiens 210,000 years ago, and Israel remains 177,000 years ago, which suggests that modern man left Africa much earlier than thought and traveled much further.

And now we are learning that tools from 45 thousand years ago were found in Mongolia, which means that man arrived there much earlier than we expected. What’s more, there is a good chance that the place of finding the remains is where our ancestors first mixed with mysterious Denisovans, because scientists date this meeting around this time. He is an undefined systematic taxa of the Paleolithic man who lived about 41,000 years ago, or at least this is what remains found in Denisowa Cave in Siberia suggest – thanks to his genes, homo sapiens was able to adapt to life at high altitudes and survive oxygen deficiency in the Tibetan Highland.

The place is called Tolbor-16 and is located along the Tolbor River in the northern part of the Changi Mountains, during research in 2011-2016 thousands of stone artifacts and weapons were found there. Similar tools could be found in nearby regions, such as Siberia or northwestern China, suggesting that man was widely spread across the continent. According to the researchers: – The most intriguing fact is that these items were produced in a very complicated but methodical way and it seems that they were typical for a certain group of people sharing technical and cultural background.

And although the team did not find any human remains on the site, they believe that the tools belonged to homo sapiens, and not other species such as the Neanderthal man or Denisowa Cave. Mainly because 826 tools found are very similar to the technology of our species from the early Upper Paleolithic, and because the site is dated to 45,000 years, the time frames also agree. In short, the finds are evidence of the presence of modern man in Mongolia much earlier than we thought, as confirmed by scientists also found the remains collected there by man for the consumption of animals, such as cattle, bison, sheep, goats and horses.

Is the pilot flying with us? No! The Pentagon will convert all aircraft into autonomous ones

The Pentagon has a very interesting plan, which is supposed to result in a rapid transformation of any aircraft into a fully autonomous one in just a few hours and using it to carry out the planned mission. Does it sound scary?

Military engineers are developing a project called ROBOpilot techadvices. There is an advanced robot behind it that can be quickly installed on board any aircraft and used to turn it into a remote-controlled or autonomous flying vehicle. The domain of this technology is to be the absence of interference in the electronic and mechanical systems of machines.

The role of the robot would only be to perform actions identical to those of a human pilot. Such an idea may not seem to make sense, because for many years, for example, fully autonomous drones have been produced and used, but here it is about regular manned aircraft, of which there are in the world and will be the most many years ago.

Installing ROBOpilot on virtually any aircraft is supposed to be child’s play. If during the mission you need to transport soldiers or equipment with a machine other than military, then you can quickly convert it into an autonomous and successfully carry out a task that was not previously achievable.

The Pentagon does not hide that in the future this role will be taken over by fully autonomous and advanced humanoid robots, as it should be from the beginning, but for now this technology is still being tested, so do not expect too much. The time will come for miniaturization and embellishment to make the robot look like a Terminator. Soon robots such as Valkyrie and ATLAS will play this role.

Their task is mainly to help those in need after various natural disasters. However, the Pentagon does not hide that it also sees such machines on the battlefield. Can you imagine that the robot supports soldiers in the mission, and when the need arises, it takes soldiers on their backs, throws them into the helicopter, sits at its controls and safely transports them to the base? This is what ROBOpilot is supposed to look like.

Starman has already completed full orbit around the Sun in his red Roadster

The Tesla sports car is one of the most interesting objects currently roaming the solar system. It is also a car that has set many records in the world of astronomy and automotive.

The red athlete from Tesla has already traveled an unimaginable 1 billion 225 million kilometers. There are currently 37 million kilometers of roads on our planet. Roadster would have driven them all over 33 times. All thanks to the speed with which it moves. At the moment it is 120 thousand kilometers per hour.

Starman is the first mannequin and Roadster is the first car to have all orbit around our daytime star. We remind you that the start of this unique mission took place in February 2018. At that time, the Falcon Heavy rocket, the most powerful currently used in the space industry, also had its first test streaming audit.

Many space enthusiasts wonder if the car will ever get very close to Earth on its journey through the solar system. So researchers from the University of Toronto decided to check if this is real. The advanced simulations they carried out showed that this would happen as soon as possible, and quite soon.

In 29 years the sports car will be quite close to our planet (for space conditions), and in 2091 close enough that you will be able to see it from the Blue Planet using ordinary telescopes. Perhaps future SpaceX employees will try to catch him and download him to Earth ?! We can be sure of one thing, the Roadster will never hit Mars or the Sun.

Elon Musk says that it is in some sense a hibernation chamber for terrestrial bacteria that went with him on a journey through space. After all, they are also a backup of earthly life. If our planet ever had a mass destruction of species, then such an unusual bank of microorganisms will allow survivors or foreign civilizations to try to recreate life on Earth, or at least learn its history.

Virgin Galactic presents the luxurious hall of its space port

Richard Branson, head of the Virgin group, announces the opening of a new chapter in the world of space tourism. Later this year, commercial flights to Earth’s orbit will be available to all those seeking extreme sensations.

The company already has a ready-made space ship called VSS Unity, which can take 6 people on board and offer them breathtaking views of the planet from a space perspective world top technology. Take-offs of tourist flights are to take place from the famous spaceport called SpacePort America, located in the state of New Mexico. This facility was created specifically for the future of mass flights into space. According to the latest research, they will enjoy enormous interest, regardless of the high ticket price.

Now a picture of the luxurious and practically furnished hall of the facility has appeared on the company’s profile on Twitter. It is in it that space tourists will wait for the flight and relax after an exciting flight. However, to be completely happy there is only one more, but the most important issue is tickets. Virgin Galactic has still not announced the official date of the first flight.

Experts predict that the progress of work in SpacePort America itself and related to the VSS Unity tests indicate the first commercial flight at the end of this year or at the beginning of 2020. The company still needs to finish everything to make tourist travel into space fully safe. If an accident happened, it would mean the end of business for the company. The decrease in customer confidence, suspension of flights for many months, huge financial losses would certainly be used by the competition in the form of the boss of Amazon and his company Blue Origin.

Dating applications reveal the location information of more than 10 million users

Although it seems unbelievable, it is sufficient now that an efficient hacker knows our username to easily find us in reality.

According to sociologists from Stanford University, online dating applications are currently the most popular form of pairing, with the result of nearly 50% of all heterosexual couples – in the monitored time between 2009 and 2017 this trend was constantly growing. And although most of us are aware that our presence on these types of websites is far from anonymous, mainly due to the multitude of information we share in them, e.g. the employer, address or current location, hardly anyone expects that it is even a gold mine for hackers.

The more so, as it turns out, many dating applications have a certain vulnerability in the programming interface (API), thanks to which hackers are able to access our location and use it for any purpose. And it should be emphasized that the only thing that such a person needs is our username. The vulnerability was discovered by the security company Pen Test Partners, which managed to demonstrate the attack using it and gain access to information about the place of residence or work of specific users.

Researchers have revealed that only the Romeo, Grindr, 3Fun and Recon applications could expose up to 10 million users in this way! By the way, they also confessed that the reaction of the creators of these popular websites was mixed – Romeo explains that their application has the option of providing an approximate location, but it is not turned on by default, Recon assured that he is already working on an appropriate fix to reduce the precision of location, and Grindr did not he decided to answer (earlier he claimed that he gives a vague location, which is not a threat, although Pen Test Partners tests showed something else).

As for 3Fun, the researchers say it is most vulnerable to attacks, easily sharing not only the location, but also the recording of conversations, photos and sexual preferences. In short, it’s not safe, and Google and Apple should definitely bend over creating an API for dating applications so that developers can reduce the accuracy of location data themselves. Is there a chance? Most likely yes, since both giants are already removing from their stores dating applications that allow the use of too young users, but it does not change the fact that we should also be aware of the risks that can result from providing their data on the web.

The Japanese announce the possibility of choosing the sex of the child before conception

It looks like we have lived to see a real breakthrough that may soon affect our lives, because thanks to a special technique of semen separation, scientists managed to grow mice of their choice.

Only a few dozen years ago, parents had to wait until the birth of their child to find out about his sex, later ultrasound examination entered the action, which significantly shortened the time of uncertainty, and now … maybe in some time we will be able to choose the toddler’s sex before conceiving ! We have just got a breakthrough in the field of genetics, all thanks to Japanese researchers who managed to develop a method that would allow them to select the sex of the entire mouse litter earlier.

The research took place at Hiroshima University, where scientists did everything to find biomarkers that would be able to distinguish X chromosomes from Y chromosomes that are transmitted by sperm and are responsible for the offspring of female and male in turn. Similar attempts to distinguish them before conception have been made before, but only the latest work has advanced this issue. Analyzes in mice show that the X chromosome carries more genes than the Y chromosome, and researchers have identified around 500 that were active and unique to the semen carrying the former and absent in the latter.

Then, of these 500, 18 were identified that can affect receptors in such a way as to impair the mobility of the semen carrying female DNA – and this allows chemical procedures targeted at such receptors that successfully inhibit the ability of sperm to move. After applying this technique to the sperm of mice, semen traveling at different rates was successfully obtained, and as a result, the X chromosome-carrying spermatozoa were separated from the Y chromosome.

When the faster group was used for fertilization, the litter was 90% male, and the selection of the slower group resulted in 81% female litter. Of course, it is still far from ideal, or a certain gender selection, but this is a significant advance over the traditional either boy or girl. Scientists, however, ensure that the work will continue because, in the context of the rapid climate change, the sex selection of offspring will be crucial, especially for farm animals, not humans – for example, male cows provide more meat than female ones. Either way, innovative methods are expensive, and carry the risk of DNA damage, but scientists are sure that one day they will be safe and accessible to people.

The first nuclear reactor in history will fly to Mars in 2022

In the shadow of a small nuclear disaster in Russia, related to a failed maneuvering missile test, NASA announced that it already has a powerful nuclear plant ready to fly to the moon and Mars.

This powerful source of electricity is called Kilopower and will ensure the normal existence of people in the extreme environment there. The agency has already completed work on the Space Technology Mission Directorate (STMD) project, which created a compact nuclear reactor. A few months ago, the project received the Gears of Government President’s Award Winners, which is one of the most important awarded by the President of the United States.

NASA announced that as early as 2022 it will be ready to send it to the Moon or Mars and carry out experiments related to it. The agency does not exclude SpaceX support in this matter. The company can take the device to a natural satellite of our planet using the Starship ship in 3 years, which is before the United States planned manned mission under the Artemida program.

Kilopower’s role will be to provide electricity to power lunar or Martian bases, heat them and provide energy for the operation of equipment and devices. The space mobile nuclear reactor has been successfully tested in recent months by NASA engineers from Glenn Research Center and Los Alamos National Laboratory.

The reactor is maintenance-free, has a power of 10 to 40 kilowatts, and is able to supply electricity to two houses for 10 years without any servicing. Uranium-235 is found in the reactor core. It is surrounded by a beryllium oxide coating that catches neutrons and reflects them back to the core, improving the effectiveness of the self-regulating fission reaction. The reactor operation is controlled by means of a single bar with boron carbide.

Heat from the reactor is collected and transferred by means of sodium-filled passive heat pipes. They provide heat to a set of high-performance Stirling engines. These are closed-loop engines and operate at temperature differences that cause the piston to move back and forth, like the piston in an internal combustion engine, though using a compressible gas medium instead of an exploding mixture of gasoline and air. At the same time, it cools the reactor with a heat sink (which looks like an umbrella), and also drives a turbine to generate electricity.

The reactor design is modular. This allows you to connect several of them into a network and generate much more needed electricity for a large base. So the first colonizers of the Moon and Mars will have as much energy as they need.

Porsche reveals Taycan’s electric release date. See the sprint from 0 to 200 km / h

The Zuffenhausen concern is not going to lag behind the competition and finally wants to show the world that it can also create an electric and ecological vehicle, and at the same time very practical and with a sporting flair.

Taycan is created as part of the Mission-E project, which Prosche has spent over a billion euros over the past few years. It paid off, because the vehicle impresses with its appearance, the latest technologies and performance not only of the brand’s fans, but also of racial racing drivers. The company said that the car is so popular that all production for 2020 has already been sold out, and it should be added here that it is about 40,000 units.

Porsche has just announced the official premiere of the vehicle, which will take place in three countries simultaneously (in Germany, China and Canada) already on September 4 at 15:00 Polish time and will be broadcast live via the Internet worldwide. According to information provided by the company’s press office, Mark Webber will participate in this major automotive event.

The most powerful version of Taycana, i.e. Turbo, is to have a battery with a capacity of 96 kWh and electric motors with a total power of over 600 MK and 880 Nm, but the torque will be able to increase for 10 seconds, at the press of a special button, up to even 1000 Nm. The vehicle is to accelerate to 100 km / h in less than 3.2 seconds, reach 200 km / h in about 11 seconds and accelerate to 261 km / h. On board will be batteries that will allow a range of up to 515 kilometers (WLTP). With a 250 kW charger, charging time up to 80 percent of the capacity takes about 40 minutes, and with 800 kW less than 15 minutes. This awesome version will cost around PLN 770 thousand.

The German concern, however, announces that plans are also even hotter version of Turbo S with four-wheel drive and power over 730 hp. Of course, cheaper versions will also appear on offer. Among them will be the one with 327 or 381 hp, rear-wheel drive and 80 kW battery. Their prices are to be affordable and lower than Panamera. Experts estimate that this could be an amount of around PLN 400,000.

In the video above you can see the latest test of Taycan, which could be carried out by automotive journalist Jonny Smith from the YouTube channel Fully Charged. Smith was delighted with the vehicle’s performance, because he was able to accelerate from zero to 200 km / h over 20 times.

An unsuccessful nuclear rocket test led to contamination in Russia

The Russian army is testing the first strategic intercontinental ballistic missile in the Arkhangelsk region called Buriewiestnik, capable of carrying nuclear weapons and nuclear-powered.

Information appeared about the unsuccessful one of the missile tests that took place yesterday (08.08) near the town of Nyonoksa, about 30 kilometers west of the city of Severodvinsk in the Arkhangelsk region, located about 1500 kilometers from Suwałki. According to local media and the Greenpace organization, there was a 20-fold increase in radiation in the area, which is supposed to indicate that a nuclear-powered missile with unrestricted range called Buriewiestnik was tested.

The TASS agency reported that at least 3 people were killed in the incident, and 15 are in very serious condition. Meanwhile, unofficial sources say that the wounded were taken to local hospitals in Severodvinsk, where they were ordered to administer Lugol’s Fluid. Local authorities advised city residents to close their windows and not go outside. The army has closed the air, land and sea area of ​​the White Sea with an area of ​​250 square kilometers.

It should be emphasized here that international law prohibits the use of nuclear propulsion in missiles and rockets. Meanwhile, Russia has been developing such weapons without hindrance for several years. The Kremlin has announced that Buriewiestnik is a retaliation weapon and, together with the underwater drone, Poseidon are to effectively raze a hostile country that decides to launch a nuclear attack on Russia. Interestingly, Poseidon is able to carry on board a nuclear weapon with an unimaginable power of 100 megatons, which is twice as powerful as the largest detonated in human history and 6,000 times than the one dropped on Hiroshima.

This is another incident with background radiation that occurred in Russia, and the government is hiding detailed information about it as soon as possible. Although the 20-fold increase in radiation should not pose a threat to the population, let alone the whole world, the growing political tension on the US-Russia-China line and the construction of missiles, rockets and vehicles carrying and nuclear-powered vehicles by these powers is seriously worrying for secretly preparing for World War III.
