Created underwater robot octopus - VIDEO
In Stock from nature there are many clever ways efficient movement across the expanses of the World Ocean. For example, cephalopods fill the cavity inside the body with water and then with force pushed back the liquid, while developing a significant speed while moving forward.

That octopus inspired a team of researchers from the University of Southampton, Massachusetts Institute of Technology (MIT) and the Alliance SMART to create a robot that moves the same way.

The length of the body of the first prototype of the device was 30 centimeters. Article published his description of the developers in the publication Bioinspiration and Biomimetics.

Polycarbonate skeleton robot developers printed on 3D-printer. The only moving part of the device - a flexible outer shell, which is also a "stored energy".

Water enters into the robot by an external pump casing and inflates. Once the injection is stopped, it just shoots out, propelling the device forward. Fins in the rear of the robot allow it to move in a straight line, and the hard skeleton does not allow the outer shell to lose the necessary streamlining after the next breakthrough.

This simple scheme is very effective, despite the fact that the water-filled robot as octopus and live in the same position is not streamlined. After the device is capable of overclocking less than a second to overcome to 10 of her hull lengths.



During the last test robot dispersed one kilogram payload up to 9.7 kilometers per hour. Nothing like this could not be achieved before any underwater vehicles.

"Man-submersibles have always been so streamlined as possible, but not one of them failed to reach the speed of movement in at least one of his body for a second, except torpedo, which are equipped with a huge amount of fuel, - says the head of the study, Dr. Gabriel Weymouth (Gabriel Weymouth) in a press release the University of Southampton. - Solids always give energy to the surrounding water, but rapidly shrinking form our robot allows you to use it for a powerful move forward. "Scientists have calculated that an increase in the size of the robot, they will be able to improve its performance.

The researchers believe that their development will sooner or later will be used in the construction of underwater vehicles for various purposes. Moreover, the results allow for a fresh look to other engineering areas where resistance is crucial, for example, the design of an airplane wing.

Prospects of artificial intelligence in the near future - VIDEO
We live in a world of "smart" objects; smart phones, watches, cars continue to grow and spread. But while the term smart (smart) originally belonged to the more advanced features of these devices, rather than to their cognitive abilities, change is coming.


Before we begin, let us denote what is artificial intelligence (AI) in its broadest definition. AI refers to a computer program designed to perform complex tasks that have historically required the presence of the human intellect. This can be anything from speech recognition and decision-making to visual perception. Great goal of AI is superior to man in any field, but companies like Google and Facebook are also working on the practical aspects of daily and future of AI. For Example.

Smartphones will become even smarter

Even with a status update on social networks and self, text set to be the main function of mobile phones. And until now messaging remained in the shadows. The emergence of new messaging applications (for example, Emu), the text of correspondence can become more efficient. In fact, the application comes with a built-in assistant that gives you relevant information to your conversation. This means that you do not have to constantly copy and paste information or else constantly switch between applications to perform basic tasks.

By now, most of us are already familiar with mobile assistant Siri from Apple, built in the most recent models of the iPhone and iPod. Innovative, but is rapidly losing popularity in the service allows users to ask questions, look on the Web and set reminders simple voice dialing. However, many problems have Siri.

Microsoft, for its part, is developing a competitor to Siri as Cortana (named in honor of the AI of the popular game Halo). The company hopes to have a conversation with Cortana will not be anything different from talking to a real person. Users will be able to maintain a conversation with AI, and if Cortana will make a mistake, it will be corrected immediately and adapt gradually getting better and better. With all this, it is hardly Cortana will be the endgame for the development of AI at Microsoft.

Greater recognition of the photo

Like it to our grandparents or not, social media is not going anywhere. There are new platforms seeking to chop off a bit of our attention; old looking for new ways to make their services even better.

Facebook does not only huskies. In fact, the company employs a surprising number of artificial intelligence researchers, some of them are involved in software development for face recognition, which will recognize people more accurately than other people. This software DeepFace uses a process called verification front. It does not compare with the name of a person, but rather to determine when the two pictures shows the same person. Very soon you will be able to upload photos, and soon Facebook will suggest someone for him to specify.

At the same time (though with slightly different objectives) Google is working on a similar project. Instead, the company is engaged in face recognition software that can exact phrase to describe the scene in the photos.

For example, if you take pictures at the zoo, the software can distinguish lions tigers and bears. Description will be about the "bear sleeps on his back" and "two lions play under a tree." All this amount represents a revolutionary combination of natural language and machine vision capabilities and clearly shows that may follow this. Machines that can surely understand the content of photos and videos, and to describe it in a natural way, become powerful tools, and open the door to the world of machine intelligence - through our cameras on smartphones. This is an important step forward for artificial intelligence, and it may be fundamental to its future development.

Machine learning and the search string


Artificial intelligence, of course, is not limited to mobile and social media. There are plenty of opportunities to improve our devices and facilitate our lives. Artificial intelligence can be equipped with robots that will be safe for the people; advanced program that will be useful in business and daily affairs; first improvements will be visible on the search line, to which we are accustomed.

Again, we turn to Google, which is looking for opportunities to improve their search services with AI. For years, Google uses machine learning to understand the needs and provide the best search results. Now Google is looking for ways to better implementation of new algorithms and output into a new era of research.

Although all of these improvements has huge potential, and growing concern on the background of the development of AI. Perhaps the most active supporters of the secure AI is Elon Musk, he is so concerned about the potential of AI that is willing to pay money for something "not to release the demon out of the bottle." He recently donated $ 10 million to support research aimed at preserving AI safe for mankind.

Whatever it was, masks, as well as high profile executives from Google, Microsoft, Facebook and other large companies are included in the list of people who aspire to the future of AI. Advantages of AI in any case outweigh the risks. These people are passionate about the development of technology, software, machines that improve our lives. And although we do not know when there will be a true artificial intelligence, superior to man, we are moving in that direction every day.

Engine VASIMR (electromagnetic accelerator with variable specific impulse) would get to Mars in 39 days - VIDEO
The US space agency NASA has selected a number of companies to work on 12 projects of advanced space technologies, including the development of faster ways to travel in space.

Many of these projects are also aimed at creating conditions for living on other planets and on the development of small satellites that will study space. The projects will be implemented under the program Next Space Technologies for Exploration Partnerships, or "Next Space Technology Partnerships for further exploration" (in the English version abbreviated as "next step").

Thus, the company Ad Astra Rocket, based in Texas, has announced its work on the engine that could deliver humans to Mars in 39 days. Engine VASIMR (Variable Specific Impulse Magnetoplasma Rocket - electromagnetic accelerator with variable specific impulse, which uses plasma as a fuel, developed since 1999. About him speak for several years, as it can reduce the travel time to Mars from a few months to a few weeks though the device may be in need of a nuclear power source.



Successful testing of the prototype took place in 2013, so now NASA is considering the use of this engine in a future mission to the Red Planet.

"We are delighted with these plans and are proud to join forces with NASA in the final stages of preparation of missions, - says Dr. Franklin Chang Diaz (Franklin Chang Diaz), executive director of the Ad Astra Rocket, physicist and astronaut. - And we look forward to successful outcome of this partnership. "

Over the next three years, NASA plans to select the company about $ 10 million to improve and bring the engine until it is ready to fly into space. It is expected that after this period will be shown a new prototype device, VX-200-SS, which will be capable of continuous operation over a hundred hours.

Previous version VASIMR made 10,000 runs at high power, but they lasted less than a minute. If the engine has run for more than 100 hours, it means that developers are on the right track, and one day they will be able to install his invention to the spacecraft, experts say.

About him speak for several years, as it can reduce the travel time to Mars from a few months to a few weeks though the device may be in need of a nuclear power source.

It is expected that plasma VASIMR rocket engine will consume a relatively small amount of fuel (figure Ad Astra Rocket Company).

Successful testing of the prototype took place in 2013, so now NASA is considering the use of this engine in a future mission to the Red Planet.

"We are delighted with these plans and are proud to join forces with NASA in the final stages of preparation of missions, - says Dr. Franklin Chang Diaz (Franklin Chang Diaz), executive director of the Ad Astra Rocket, physicist and astronaut. - And we look forward to successful outcome of this partnership.

With this and some other technologies, NASA plans to develop the possibilities of exploration of the Moon and Mars.

"Commercial partners were chosen for their technical ability to create important technologies, as well as on their previous developments, many of which are used by the government - says the head of one of the departments of NASA William Gerstenmaier (William Gerstenmaier). - In the end, these developments will help us to develop strategies traveling man in the solar system. "

Three projects will develop innovative engines that will work with a capacity from 50 to 300 kW (for comparison, the power of electric current in the ion propulsion of spacecraft NASA is less than 5 kW).
More seven companies will develop space habitats for astronauts who will fly to Mars in 2030-ies.

Capsule Orion multipurpose spacecraft designed to deliver astronauts to Earth, but it also can support a crew of four people for 21 days.

However, as the journey to Mars, as long as expected, will take from several months to three years, astronauts have at this time to live in some other structure. NASA hopes that one of the funded projects will help to find a way to accommodate the astronauts during a grueling flight to a new world.



One of the companies selected Space Agency Bigelow Aerospace will build residential units, a prototype of which will be attached to the ISS in 2018.

And finally, the two companies chosen for the development of small satellites (the so-called kubsatov). They will be a secondary payload during the first rocket launch Space Launch System in 2019. This rocket powerful enough to give kubsatam opportunity to explore the distant reaches of space, rather than remain in Earth orbit. Most of these small satellites now operate there.

Time is a phenomenon, a side effect of the quantum entanglement of particles - VIDEO
Physicists say: time - a phenomenon occurring side effect of the quantum entanglement of particles. And now they were the world's first experimental results that confirm this. In 1983, theoretical physicists Don Page and William Wouters offer innovative theory based on the phenomenon of quantum entanglement. This exotic property allows two quantum particles have a common existence, even if they are physically separated. Quantum entanglement - a deep and powerful connection, and Page and Wouters demonstrated that it can be used to measure time. Their idea was that the manner in which a pair of entangled particles has evolved, is some kind of hours that can be used to measure time. But it turns out in their conception results depended on how the monitoring was carried out. One way is to compare the change in the entangled particles using an external clock, which is completely independent of the Universe. This is equivalent to a godlike observer outside of the Universe, which measures the evolution of the particles by means of an external clock. In this case, Page and Wouters showed that the particles are completely the same - time in such a scenario would not exist. But there is another method that gives a different result. In it is an internal observer and compares the evolution of particles by the rest of the Universe. In this case, the inner observer will see a change, and this difference in the evolution of particles in comparison with the rest of the time is an important measure. This is an elegant and powerful concept. It suggests that time - is occurring phenomenon that occurs in reality due to the nature of quantum entanglement. And it exists only for the observer within our Universe. Any godlike observer abroad will see a static immutable Universe as first predicted earlier quantum Wheeler-DeWitt equation. Of course, no experimental confirmation of the idea Page and Wouters no more than a philosophical curiosity. And because we have no opportunity to receive an observer outside of the Universe - it seems we do not have, and no chance of ever confirm this theory. At least it was until today. A few days ago Catherine Moreva of Istituto Nazionale di Ricerca Metrologica in Turin, Italy, and several of her colleagues were able for the first time experimentally test the ideas Page and Wouters. And they have demonstrated that the time is indeed emerging phenomenon for domestic observers, but it does not exist outside observers. This experiment involves the creation of toy Universe, consisting of a pair of entangled photons and the observer, who can measure their status in one of two ways. In the first observer measures the evolution of the system, snarling himself with it. In the second godlike observer measures the evolution in comparison with the external clock, which is completely independent of the toy Universe. The experiment itself is straightforward. Each of entangled photons has a polarization that can be changed by passage through a birefringent plate. In the first case, the observer measures the polarization of a single photon, thereby snarling with it. He then compares the result with the polarization of the second photon. The resulting difference and it will be a measure of time. In the second case, both photons and passes through the birefringent plate, which change their polarization. However, in this case, the observer measures only global properties of both photons, by comparing them with independent clocks. In this case, the observer can not notice any difference between the photons, without coming to a state of confusion with one of them. And if there is no difference, the system appears before them static. In other words - the time it occurs. "Although it is incredibly simple, our model incorporates two contradictory as it seemed before Page's properties mechanism-Wouters," says Moreva. This is a very impressive experiment. The emergence of something is a popular concept in science. In particular, recently, physicists are interested in the idea that gravity is also emerging in this phenomenon. And from here to the idea of ​​a similar mechanism of time was only one step. What's missing gravity arises - is, of course, the experimental demonstration that would show how it works in practice. That is why the work Moreva is so important - it is the first time in the world and puts an abstract exotic idea of ​​the sustainable experimental basis. But perhaps the most important result of this work is that the first time she was able to demonstrate that quantum mechanics and general relativity are not so incompatible. The next step is the further development of the idea, in particular - on a macroscopic level. It is one thing to show how the time appears in photons, and another - to understand how it occurs in humans.
