      "body": "https://hi-news.ru/wp-content/uploads/2018/05/file-20180523-51095-61ehpp.jpg\n\nPeople who consider physics boring are enormously mistaken. It is able to explain everything in the world, from terrible interactions on tiny atomic and particle scales to the behavior of entire universes. And if this is not enough, with the help of physics you can estimate how realistic the technologies of the future in science fiction are. Martin Arker, an expert in the physics of cosmic plasma, can explain many of the nuances of the work of lightsabers and the Death Star in the \"Star Wars\" universe, for example.\n\nNow he is working on assessing the realism of blaster weapons, which, among others, Khan Solo used - and how blasters can be compared to light swords. In fact, real versions of these weapons have long been developed. Therefore, when the prequel film about Solo came out, it's time to tell more about this.\n\nThe key to understanding the technology of Star Wars will be plasma - the so-called \"fourth state of matter\" (in addition to solid, liquid and gaseous). These are freely flowing electrically charged particles, which naturally interact with electric and magnetic fields. Plasma is common in space but is rarely found in nature on Earth. However, it can be created in the laboratory.\n\n<h1><b>Power Plasmoids </b></h1>\n\nA common misconception about blasters will be that it is a laser weapon. But according to the canon of \"Star Wars\" this would not make sense. Instead, the authors stated that the blaster was \"any type of long-range weapon that fired clots of intense plasma energy, often mistakenly accepted as lasers,\" and that it converted \"energy-enriched gas into a glowing particle beam that could burn the target.\" It turns out that the blaster clusters (glowing projectiles) are just drops of plasma, something like a light sword flying through the air.\n\nThe coherent masses of the plasma and the associated magnetic fields are known as plasmoids. Within the protective shield of the Earth - the magnetosphere - plasmoids are usually formed in a poorly understood process of magnetic reconnection. This is an explosive reconfiguration of the magnetic field lines, which occurs in the presence of a plasma, in particular at the place of plasma pooling. When this occurs within our magnetosphere, charged particles are accelerated toward the upper part of the atmosphere, giving birth to a polar aurora. A huge amount of material is also ejected from the Earth in the form of plasmoids.\n\nhttps://hi-news.ru/wp-content/uploads/2018/05/file-20180523-51130-seshj4.jpg\n\nHowever, creating a plasmoid on Earth is not so easy. We can demonstrate only structures that rapidly expand and dissolve in the air. The solution to this problem is to use magnets that hold the hot plasma.\n\nNevertheless, blaster clusters are shells, so they can not be supported by magnets externally throughout their movement. Fortunately, there is a solution. Since the plasma is highly conductive, it is possible to adjust the electric current in the plasmoid itself. This current will generate magnetic fields that hold the plasma. These mechanisms are known as spheromaks, and over the past twenty years they have attracted additional interest in experiments in the field of plasma physics.\n\n<h1>Real versions</h1>\nOne way to create a spheromak is to use a \"plasma railgun,\" a device that uses an external magnet to induce currents in the plasma, and also accelerates the projectile to high speeds. In fact, spheromak, living several hundred microseconds, allowed to develop a speed of up to 200 km / s. This is quite impressive and definitely allows them to be used as a weapon.\n\nIn the 1970s, the US Air Force Research Laboratory in Albuquerque established the SHIVA Star program (named after the multi-armed god in Hinduism), within which various branches of the practical application of plasma physics were developed. One of them - MARAUDER - formed the basis of one of several US initiatives to create projectiles based on plasma.\n\nThis weapon was capable of producing donut-shaped rings from plasma and lightning balls that exploded with destructive thermal and mechanical effects when hit at the target, creating a pulse of electromagnetic radiation capable of turning off electronics. But since 1993, the status of this weapon remains uncertain.\n\nThe temperatures that could be achieved in such devices were a thousand times higher than the solar ones. Having enough plasma, each clot would cause huge damage, so the blaster from Star Wars looks quite realistic.\n\nBut how could this real blaster weapon compete with another sign weapon from the Star Wars, a light sword? The blaster cluster is essentially equivalent to the blade of a light sword without a handle. But when two plasma-limited plasmas meet, a magnetic reconnection will be inevitable. That is, in the collision of two lightsabers, an explosive effect would be created, destroying both the weapon and its carriers. But with the blaster you would be far from the explosion and completely unscathed.",

The tests, recognized as successful, were held May 29, 2018 at the training ground in the Mojave Desert (California).\n\nDuring the tests, the ship separated from the carrier aircraft WhiteKnightTwo, after which it switched on the rocket engine for 31 seconds, developing a speed of 1.9 Mach numbers (2267 km / h) and gaining a height of about 35 kilometers.\n\nThe purpose of the VSS Unity tests was to test the ship's flight control systems in a supersonic mode. In recent tests, passenger seats and related equipment were integrated into the spaceplane.\n\nhttps://www.youtube.com/watch?v=AIzx6X3ub2I\n\nThe first tests of VSS Unity in supersonic mode took place on April 5, 2018. Then the ship managed to develop a speed of 1.87 Mach numbers (2231 km / h). The previous 11 flights of the spaceplane, conducted since February 2016, passed without the inclusion of a rocket engine.\n\nThe VSS Unity suborbital manned spacecraft was introduced in February 2016 as an advanced model of VSS Enterprise, which crashed in October 2014 due to a pilot error. VSS Unity and VSS Enterprise are models of the second and first generations of SpaceShipTwo, respectively.\n\nDeveloped by Scaled Composites and the spacecraft built by The Spaceship Company, the Virgin Galactic spacecraft is designed for suborbital tourist flights. The cost of such a trip for each of the six passengers is estimated at 200 thousand dollars. Virgin Galactic is hoping to begin commercial use of VSS Unity as early as 2018.",

But most robots lack tactile sensitivity, which is extremely important when interacting with various objects. However, soon everything can change because a group of engineers from Switzerland has created ultra-thin flexible cables that can transmit electronic signals when touched.\n\nFor the development are responsible engineers of the Federal Polytechnic School of Lausanne (EPFL), and, according to the publication Advance Materials, the principle of the action of flexible wires is much like the work of sensitive human nerve tissues. The basis is the fiber, within which several tens of rows of electrodes are located from the periphery to the center. Due to this, the device can react to pressure, touch and even damage. The \"synthetic nerve\" itself can distinguish the load due to the fact that different tactile electrodes are located at different depths. As the head of the project, Fabien Sorin,\n\n\"The human nervous system is very similar to a fiber-optic network, where each nerve is a cable, and inside it are electrodes. The same principle we use when creating our artificial nerves. The conductor elements are connected by plastic blocks, which have a high elasticity and are resistant to heat. \"\n\nThe creators have already filed a patent for their technology and hope that the creators of robotics are interested in their development, but even if this does not happen, scientists say that their material can easily be integrated into any field. For example, in smart clothes and wearable electronics.\n\nhttps://www.youtube.com/watch?v=KXbnV6WJJ-s",

Especially for this purpose, an algorithm was created that disrupts the recognition system, not allowing it to intrude into privacy.\n\nThe new system is built on the basis of deep machine learning, which means it is capable of self-improvement in the future. The algorithm itself uses dynamic methods of destroying the recognition algorithms. To develop a counteraction system, scientists used two AIs that fought each other. One worked to identify individuals, and another tried to break it. The result of this \"war\" was the creation of a special filter (so far only for photos) that replaces certain pixels in images in such a way that the human eye can not see the difference, but the face recognition system fails.\n\nProfessor Aarabi tested his invention on photographs of 600 people of different ethnic and gender backgrounds. As a result, it turned out that the system is able to reduce the proportion of recognized individuals from 100% to 0.5%. But that is not all. In the course of the study, a rather pleasant bonus was found: the system does not just prevent the algorithm from recognizing faces, but also does not allow you to read skin color, ethnicity, sex, facial expressions, etc., making the photo \"just a picture\" for the recognition algorithm.",

That’s more than double the cost of utility-scale solar systems, which range from 4.4 to 6.6 cents.\n\nAs it is, it’s going to be incredibly expensive and difficult to overhaul the energy system, so researchers stress that it’s crucial to follow the most cost-effective paths possible.\n\n“I think there are indeed limited political resources that can be mustered against climate change,” Borenstein said in a follow-up e-mail. “By demonstrating a very expensive way to reduce greenhouse gases, I think this could very likely be used in other states and countries as an argument against moving toward renewable energy.”\n\nThe new rule could add <a href=\"https://www.nytimes.com/2018/05/09/business/energy-environment/california-solar-power.html\">more than $10,000 </a> to the costs of building a home, raising the price tag in what’s already one of the most expensive states to purchase housing. But buyers are expected to pay lower monthly energy bills as a result of this change and eventually save money over time.\n\nBorenstein notes that these savings are effectively subsidized by other ratepayers without solar panels, net metering, and solar tax credits.\n\nCalifornia has already made <a href=\"https://www.sfchronicle.com/business/article/California-may-reach-50-renewable-power-goal-by-12354313.php\">giant strides</a>  in adding renewable-energy generation, which has started to create its own set of problems. On very sunny days, the state’s solar plants can generate more energy than the system is able to use, pushing prices into negative territory.\n\nEffectively integrating a growing supply of intermittent solar and wind energy will require adding far more storage, transmission, and smart grid systems. As it stands, the state’s grid operator lacks basic tools for monitoring, communicating, and reacting to a continually shifting supply of rooftop solar.\n\nCalifornia estimates that the new rule will cut emissions by 1.4 million metric tons over three years, which is a small fraction of the 440 million tons the state generated in 2015. As others have pointed out, policies requiring higher residential density would do far more to cut emissions, largely by discouraging people from driving cars.\n\nBut such proposals are far more controversial than solar panels. Last month, California legislators killed a bill that would have overridden local rules to allow five-story housing development along transit centers.\n\n“While additional distributed renewable electricity will be helpful, California’s climate elephant in the room remains the greenhouse gases from people driving cars,” said Costa Samaras, an assistant professor of environmental engineering at Carnegie Mellon University, in an e-mail. “Increasing the density of housing near employment centers and encouraging housing near transit, as well as the continued electrification of transportation, are essential to deep decarbonization in California.”",

The company will also show a prototype of a flying taxi at the Uber Elevate Summit, which will be held in Los Angeles this week.\n\nIn general, the design of the device is more like a large quadrocopter, rather than a flying car. A few rotors of a flying taxi will allow vertical takeoff and landing. The body of the apparatus is closer to the aircraft fuselage than to the helicopter. The flying Uber taxi will work on electricity, therefore, as the journalists of the TV channel note, the device will be quieter, more efficient and more economical than an ordinary helicopter.\n\nhttps://www.youtube.com/watch?v=-XFbyWAUwp4\n\nAccording to Uber CEO Dara Khosrovshakhi, people will be able to order a flying taxi through a mobile application, and then head to the nearest airport on the roof of one of the buildings. In addition, the company plans to offer a separate payment service: each unit will be able to take on board up to four passengers, which will reduce the final cost of the flight.\n\nAccording to various sources, the company's early prototype demonstration probably decided to divert public attention from the incident that occurred in Arizona in March of this year. Recall that an unmanned vehicle Uber knocked a bicyclist crossing the road in the wrong place in the dark.\n\nThe investigation of this incident is still ongoing, and as it became known, new details emerged in it. According to the latest data, the accident was caused by the fault of \"incorrectly configured software\". It's about software, which, based on the received data from sensors and cameras, gives the computer a command to \"ignore obstacles on the road.\"\n\nThe software should have been programmed to stop the car in front of really serious obstacles. As representatives of the company explained, this measure was forced, since otherwise the drone would have braked before every flying on the road a package. Unfortunately, a mistake in programming led to a tragedy - the car at full speed rode into the bicyclist.",

The company Rare Bits literally does it. Their new product is the digital goods market, built on blockbuster technology. Employees of the company consider modern days the heyday of virtual goods.\n\n\n\nThree of the four employees of Rare Bits in the past worked in Zynga - the company that developed FarmVille. FarmVille is an incredibly popular game on Facebook. At the peak of its popularity, it had over 80 million active users a month. For the game, Farm Cash's own payment system was developed, where users could spend money on buying virtual things for a virtual farm.\n\nIn other words, a virtual goods store is not the newest idea, but Rare Bits is not just a store. The co-founder of the company Daniel Lee said that if before all the virtual values ​were stored on the developer's server, which at any time could deprive you of them, then with the technology of the blockade everything changes. Blocking provides a digital registration pointing to virtual property, which creates interest not only in the purchase of virtual goods but also in their sale.\n\nIn other words, now, if you own something on the Internet, it really means something.

      "body": "https://americarichest.com/wp-content/uploads/2017/12/facebook-messenger-boss-david-marcus-joins-coinbases-board-1280x640.jpg\n\nLast Tuesday, the head of Facebook Messenger, a popular service from the creators of a well-known social network, announced that he was leaving his post. David Marcus will remain with Facebook, but will take on a new direction for the company. His task will be to find the use of blockchain technology in Facebook.\n\nAt the disposal of Marcus is a small team of people who will help him find the best application of the blockchain inside Facebook. Earlier, Mark Zuckerberg, CEO of the company, said that he was studying the use of crypto-currency within the social network. The technology of blockchain lies at the heart of bitcoin and many other crypto-currencies.\n\nThe news also came amid reorganization inside Facebook. Messenger is now part of what the company called \"Family of Apps\" along with Instagram, WhatsApp and Facebook. All this unit will be headed by the Chief Product Officer Chris Cox. Team Messenger will pass under the direction of the executive director Stan Chudnovsky.\n\nDavid Marcus started working for Facebook four years ago. He joined the company from PayPal, where he served as president. He is a big fan of crypto currency. Marcus did not disclose details about what ideas currently exist on the subject of using blockchain , but it is clear that the potential is very large.",
