after a space flight The ball for the opening match of the 2018 World Cup returned to Earth on Sunday

The ball for the opening match of the 2018 World Cup returned to Earth on Sunday after a space flight.

The ball was flown to the International Space Station in March and returned to Earth aboard the Soyuz 07 spacecraft.

Along with Russian astronaut Anton Shakapelerov, Scott Tengel and Japanese Norrisheji Kanai landed in Kazakhstan near the town of Gizkazagan.

The World Cup begins on June 14 at Moscow's Luzhniki Stadium, which will be the scene of the opening match between Russia and Saudi Arabia.

The 21 matches of the World Cup will be held on 12 venues in 11 Russian cities with 32 teams from 14 June to 15 July.

more dangerous than nuclear weapons WARNING !!

It’s hard to believe how far we’ve come. We launched just a few years ago with our surveillance drones, and in this short amount of time, we’ve retooled cutting-edge artificial intelligence and machine learning techniques, such as deep learning and convolution neural networks, into hardware systems that governments and peace-keeping agencies can use to keep their troops safe. No more sending our brave patriots home in coffins. Now the artificial intelligence does all of the work. Our autonomous weapons are small, fast, accurate, and unstoppable.

And they are just the beginning. Smart swarms. Adaptive adversarial learning. On-the-field robust target prioritization. AI-powered tactics and strategy a Go master would envy. This is the future of peacekeeping.

About the technology
Our Autonomous anti-Personnel Systems (APS) employ an array of cutting edge AI technology, including:
Obstacle avoidance: the neural network copied into every APS has been trained through the equivalent of millions of hours in varied simulated environments to avoid obstacles, even when they are in motion.
Stochastic movements: trained on thousands of movies of mosquitoes and other flying insects, our drones will defeat any attempt to anticipate their flight patterns.
Efficient munitions: using precise targeting, we are able to drive the size of a projectile and propellant to a bare minimum.
Facial recognition: it’s in your iPhone and it’s in APS, along with parallel networks to identify targets by gait, gender, uniform, even ethnicity.
Multiple self-location protocols: along with GPS, our APSs use a variety of proprietary technologies to locate themselves in space.
Incommunicado and EMP hardened: once an APS gets flying, there is no way to stop it electromagnetically by jamming, spoofing, zapping, or anything else.
Big data links: we’ve acquired and consolidated a host of data sets. Using our servers you can reliably tie individuals to their individual characteristics for later targeting. We’d tell you more, but as the joke goes, then we’d have to kill you. (And of course, since you’ve visited this site we know exactly who you are.) Again, just kidding!
The Stinger anti-Personnel System
The Stinger is our first mass-produced mini-weapon. It’s fully autonomous with wide-field cameras, tactical sensors, facial recognition, processors that can react 100 times faster than a human, and its stochastic motion is an anti-sniper feature. Inside it are three grams of shaped explosives that offer just enough power to penetrate the skull and kill the target with surgical precision.
All About Teamwork
Vanguard Delivery and Breaching System
Each delivery system can carry 18 Stingers. The delivery system arrives at a building or some other enclosed space (car, train, plane, you name it), releases its cargo, attaches to the barrier, and blows a hole in the wall or window. The Stingers can then enter the building and find their targets. These systems are virtually unstoppable. Target terrorist cells, infiltrate enemy compounds — the bad guys will not be able to defend against them.
Identify and Target Only the Bad Guys
The EyeFire Target Identification System
All of our systems can use facial recognition to identify a predetermined target, but what about threatening underground movements or secret terrorists cells? It’s not like there are public hashtags that terrorists use to identify themselves. The EyeFire Target Identification System isn’t just the little bot, but an entire big-data processing system that can scan billions of tweets, posts, pages, videos, and anything else you can find online to identify patterns indicative of terrorist activity. The system then crawls that data to identify IP addresses and GPS locations to identify the suspect posting the dangerous messages. It can also track down who the suspect is collaborating with. We’ll help you weed out the bad guys.
SoftTouch Bot
A new form of regime change. The world is full of deadly leaders who are harming their citizens and threatening global security. Until recently, it’s been hard to oust these bad actors: they’re hard to get to and even if someone can get close enough for the kill, an obvious murder can lead to greater unrest. But these little bots are about the size of a bee, they can fly anywhere, get inside any building, hide inside any vent, and strike while the target sleeps. The question literally becomes: what’s your poison? The bots can be filled with a lethal dose of the poison of your choice, and the mark left on the body will be barely noticeable, looking like nothing more than a bug bite.

Top 10 Most Powerful Waterfall in The World

I can't belive this, clothing that 'grows' at the same time your son.

Children grow seven sizes during their first two years and this amounts to a large amount of wasted 


Now, the recent graduate of the Royal College of Art in London, Ryan Mario Yasin, has created a range of children's clothing which he named: Petit Pli. It is a system of folds that allows garments to stretch to adapt even after body growth. Your clothes are designed to adapt from 6 to 36 months of age, which translates to at least 6 different sizes. The idea arose after Yasin realized that his nephew was not wearing his clothes for very long, and thanks to his training as an aeronautical engineer specialized in deployable structures, he was able to create clothes with folds similar to the covers of
some spacecraft, as small satellites.


 The structures expand and contract in synchrony with the child's movement. Yasin expressed. Later he experimented with different types of fabrics in his own home, including the addition of folds and literally baking fabrics in his kitchen oven. So far the materials made by him are still pending patent. Technically Yasin has created the most advanced children's clothing in the world.

 Petit Pli garments are made with ultralight materials that resist climatic adversities such as wind and water, as well as perspiration. The clothes are comfortable and functional, and adapt to the movement of the child. In addition, they are easy to pack and clean.


In its initial form, the pleated shirts and pants are quite small, since they serve to dress a baby for 6 months. As children grow, the material can unfold, expanding to a small size of 2 and a half years or 3. You could not miss a demonstration video where you can see how this type of clothing is stretched, observe:

The first fight of giant robots between The United States and Japan. there is already a winner!

Voltron Vs. Mazinger Z, Robotech Vs. Macross, giant robot fights ... did you ever imagine something similar in your childhood? Well, we are getting closer. Finally, the first fight between giant robots piloted from inside was carried out.

Two teams, one US and one in Japan, with robots created at both ends of the world: Kuratas Vs . Eagle Prime and Iron Glory. That's right, the Japanese had to fight against two Americans. The challenge was launched two years ago by the United States and the creator of Kuratas accepted.

For two years both teams prepared their megabots to face death. The science fiction fantasies became reality when the robots piloted by their creators fought in Japan. The Japanese defeated the first but lost with the second.

The duel was in an abandoned metallurgical, the perfect scenario. It was broadcast on Twitch in real time but MegaBots Inc. , the US team, posted 26 minutes of the show on YouTube.

The United States lost with its first robot and was the winner of the confrontation between Kuratas and Eagle Prime.

In the fight, the Iron Glory robot of the USA. UU was knocked out by the Japanese Kuratas almost beginning hostilities.

His paintball cannon was no match for his 13-foot, half-ton fist. In the second round , the MegaBots pilots returned with Eagle Prime, with a mechanical claw and a machine gun.

They battled to deliver a death blow, got stuck and the Kuratas drone made life more difficult for them. In the final round things got more complicated for Kuratas. This was a better fight. There were punches, shots and strategy but they got caught in a hug and had to pause.

When the fight restarted, the Americans armed themselves with a saw to cut rocks and Kuratas attacked with a machine gun. They almost crushed the commentators and finally Eagle Prime used a mechanical saw to dismember the Suidobashi Heavy Industry robot . Everything ended in butchery.

The fight that was cooked for two years had simple rules. The three ways to win were: knock out the opponent, disable the opponent and let the pilot give up.

The people on the Internet saw the Americans as Montoneros and complained that a single Japanese had to fight with two Americans. Although Americans believe they won, many consider it a draw.

Also, it seems that there were more differences in the weights. Eagle Prime was a robot of another category because of its weight. It was like facing a featherweight with a full weight, like Pacquiao against Myke Tyson. Either way, we hope that this fight is just the beginning of a new championship.

This is the video that gives the technical cards of the robots and a summary of the fight:

I can't belive this Extremely Powerful F-22 Raptor

The Lockheed Martin F-22 Raptor is a fifth-generation, single-seat, twin-engine, all-weather stealth tactical fighter aircraft developed for the United States Air Force (USAF). The result of the USAF's Advanced Tactical Fighter program, the aircraft was designed primarily as an air superiority fighter, but also has ground attack, electronic warfare, and signal intelligence capabilities.The prime contractor, Lockheed Martin, built most of the F-22's airframe and weapons systems and conducted final assembly, while Boeing provided the wings, aft fuselage, avionics integration, and training systems.

The aircraft was variously designated F-22 and F/A-22 before it formally entered service in December 2005 as the F-22A. After a protracted development and despite operational issues, the USAF considers the F-22 critical to its tactical air power, and says that the aircraft is unmatched by any known or projected fighter. The Raptor's combination of stealth, aerodynamic performance, and situational awareness gives the aircraft unprecedented air combat capabilities.

The high cost of the aircraft, a lack of clear air-to-air missions due to delays in Russian and Chinese fighter programs, a ban on exports, and development of the more versatile F-35 led to the end of F-22 production.[N 1] A final procurement tally of 187 operational production aircraft was established in 2009, and the last F-22 was delivered to the USAF in 2012.

British submarine shows the moment it breaks the ice and emerges into the Arctic

A Royal Navy submarine has demonstrated its ability to emerge by successfully breaking ice in the Arctic Ocean in North America.

The HMS Trenchant , an attack submarine, led his five weeks of exercises on Ice 2018, said Darryl Wood of Dvidshub in a video statement.

According to  the British Royal Navy on April 19, the ship emerged at the top of the world with freezing temperatures at approximately 4,425 km from its base in Plymouth, southwest England.

Trenchant joined US submarines USS Connecticut and USS Hartford to conduct combat drills coordinated by the US Navy's underwater Arctic laboratory. He broke the ice at the North Pole five times, according to the Navy.
All three conducted rigorous tests designed to "test the skills of divers in exploiting the Arctic Arctic's cold climate" .
